There is a growing number of studies on the association between ambient air pollution and adverse pregnancy outcomes, but their results have been inconsistent. Consequently, a comprehensive review of ...this research area is needed. There was a wide variability in studied pregnancy outcomes, observed gestational windows of exposure, observed ambient air pollutants, applied exposure assessment methods and statistical analysis methods
Gestational duration, preterm birth, (low) birth weight, and small for gestational age/intrauterine growth restriction were most commonly investigated pregnancy outcomes. Gestational windows of exposure typically included were whole pregnancy period, 1st, 2nd, 3rd trimester, first and last gestational months. Preterm birth was the outcome most extensively studied across various gestational windows, especially at the beginning and at the end of pregnancy.
Particulate matter, nitrogen dioxide, ozone, and carbon monoxide were the most commonly used markers of ambient air pollution. Continuous monitoring data were frequently combined with spatially more precisely modelled estimates of exposure.
Exposure to particulate matter and ozone over the entire pregnancy was significantly associated with higher risk for preterm birth: the pooled effect estimates were 1.09 (1.03–1.16) per 10 μg/m3 increase in particulate matter with an aerodynamic diameter of 10 µm or less (PM10),1.24 (1.08–1.41) per 10 μg/m3 increase in particulate matter with an aerodynamic diameter of 2.5 µm or less (PM2.5), and 1.03 (1.01–1.04) per 10 ppb increase in ozone. For pregnancy outcomes other than PTB, ranges of observed effect estimates were reported due to smaller number of studies included in each gestational window of exposure.
Further research is needed to link the routine pregnancy outcome data with spatially and temporally resolved ambient air pollution data, while adjusting for commonly defined confounders. Methods for assessing exposure to mixtures of pollutants, indoor air pollution exposure, and various other environmental exposures, need to be developed.
The open access book discusses human health and wellbeing within the context of built environments. It provides a comprehensive overview of relevant sources of literature and user complaints that ...clearly demonstrate the consequences of lack of attention to health in current building design and planning. Current designing of energy-efficient buildings is mainly focused on looking at energy problems and not on addressing health. Therefore, even green buildings that place environmental aspects above health issues can be uncomfortable and unhealthy, and can lead to public health problems. The authors identify many health risk factors and their parameters, and the interactions among risk factors and building design elements. They point to the need for public health specialists, engineers and planners to come together and review built environments for human wellbeing and environmental sustainability. The authors therefore present a tool for holistic decision-making processes, leading to short- and long-term benefits for people and their environment.
Hymenoptera venom–triggered anaphylaxis (HVA) affects up to 8.9% of the general population and is the most frequent cause of anaphylaxis in adults, accounting for approximately 20% of all fatal ...anaphylaxis cases. Quite often, a fatal reaction is a victim’s first manifestation of HVA. Mastocytosis represents one of the most important risk factors for severe HVA. We analyzed patients with documented fatal HVA for the presence of underlying clonal mast cell disorder (cMCD). Here, we report three cases of fatal HVA, with undiagnosed underlying cMCD identified by the presence of the peripheral blood and/or bone marrow KIT p.D816V missense variant postmortem. In the first case, anaphylaxis was the initial episode and was fatal. In the other two cases, both patients were treated with specific venom immunotherapy (VIT), nevertheless, one died of HVA after VIT discontinuation, and the other during VIT; both patients had cardiovascular comorbidities and were taking beta-blockers and/or ACE inhibitors. Our results point to the importance of screening all high-risk individuals for underlying cMCD using highly sensitive molecular methods for peripheral blood KIT p.D816V variant detection, including severe HVA and possibly beekeepers, for proper management and the need for lifelong VIT to prevent unnecessary deaths. Patients at the highest risk of fatal HVA, with concomitant cardiovascular and cMCD comorbidities, might not be protected from field stings even during regular VIT. Therefore, two adrenaline autoinjectors and lifelong VIT, and possibly cotreatment with omalizumab, should be considered for high-risk patients to prevent fatal HVA episodes.
IntroductionSystemic allergic reaction (SAR) to a Hymenoptera venom is a potentially life-threatening disorder. The rate of SAR between beekeepers in comparison with a healthy individual is ...different. The risk for an SAR is particularly high in beekeepers due to their persistent or seasonal exposure to the stinging Hymenoptera. We aim to provide a critical appraisal and a synthesis of evidence-based data from epidemiological observational studies, focusing on SARs to a Hymenoptera venom and the associated risk factors for SARs in beekeepers worldwide.Methods and analysisSearching will include seven electronic databases for published studies without language restrictions, from inception up to 3 August 2021, and it will be rerun for all electronic databases prior publication. Only epidemiological observational studies in beekeepers will be included. The risk of bias in the included studies will be appraised by using the Joanna Briggs Institute Critical Appraisal Checklist for Analytical Cross-Sectional Studies and the Newcastle-Ottawa Scale, adapted for cross-sectional studies. For the certainty of evidence, the Grading of Recommendations Assessment, Development and Evaluation approach will be used. Qualitative synthesis will be presented in a tabulated format with the selected characteristics across primary studies and the main outcome of interest. A meta-analysis is planned to be performed if there will be a sufficient number of homogeneous studies with complete data. The Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols 2015 statement will guide the reporting of this systematic literature review.Ethics and disseminationNo ethics approval is needed to conduct the systematic literature review since it will be solely based on the published literature. Findings will be disseminated through the relevant conferences, peer-review and open-access journals.PROSPERO registration numberCRD42021260922.
BackgroundBeekeepers represent a high-allergic risk population group due to their unavoidable seasonal or persistent exposure to the elicitors of Hymenoptera venom allergy, bees in particular. A ...systematic literature review and meta-analysis aimed to estimate the prevalence of self-reported systemic allergic reaction to Hymenoptera venom among beekeepers worldwide.MethodsWe rigorously reviewed and conducted meta-analysis on observational studies retrieved from seven electronic databases (MEDLINE via PubMed, Web of Science Core Collection, Scopus, Academic Search Complete, ScienceDirect, Cumulative Index to Nursing and Allied Health Literature, Zoological Record), spanning data from inception to August 1, 2023. The Joanna Briggs Institute Prevalence Critical Appraisal Tool was employed to assess the risk of bias. A meta-analysis was conducted to synthesize evidence.ResultsOut of 468 studies, eight original articles met the inclusion criteria. The estimated overall lifetime and one-year prevalence of self-reported systemic allergic reaction to bee venom were 23.7% (95% CI: 7.7-53.4) and 7.3% (95% CI: 5.8-9.2), respectively. The estimated lifetime prevalence of self-reported systemic allergic reaction to bee venom for grades III-IV (severe systemic allergic reaction) was 6.0% (95% CI: 3.0-11.7). In general, substantial heterogeneity and a high risk of bias were observed across the majority of studies. The impact of geographical location and climate differences on the estimated lifetime prevalence is suggestive for severe systemic allergic reaction.ConclusionsFuture observational cross-sectional studies should employ rigorous study designs, using validated questionnaires, and thoroughly report the observed health outcomes, verified by physicians.
Speleotherapy is one of the non-pharmacological methods for the treatment and rehabilitation of patients with chronic respiratory diseases, especially those with chronic obstructive pulmonary disease ...(COPD) and asthma. On the one hand, one of the alleged main advantages of speleotherapeutic caves is the low microbial load in the air and the absence of other aeroallergens, but on the other hand, due to the lack of comprehensive air monitoring, there is little information on the pristine and human-influenced aerobiota in such environments. The aim of this study was to assess the anthropogenic effects of speleotherapy on the air microbiota and to investigate its potential impact on human health in Sežana Hospital Cave (Slovenia). From May 2020 to January 2023, air samples were collected in the cave before and after speleotherapeutic activities using two different volumetric air sampling methods—impaction and impingement—to isolate airborne microbiota. Along with sampling, environmental data were measured (CO2, humidity, wind, and temperature) to explore the anthropogenic effects on the aerobiota. While the presence of patients increased microbial concentrations by at least 83.3%, other parameters exhibited a lower impact or were attributed to seasonal changes. The structure and dynamics of the airborne microbiota are similar to those in show caves, indicating anthropization of the cave. Locally, concentrations of culturable microorganisms above 1000 CFU/m3 were detected, which could have negative or unpredictable effects on the autochthonous microbiota and possibly on human health. A mixture of bacteria and fungi typically associated with human microbiota was found in the air and identified by MALDI-TOF MS with a 90.9% identification success rate. Micrococcus luteus, Kocuria rosea, Staphylococcus hominis, and Staphylococcus capitis were identified as reliable indicators of cave anthropization.
The objective of our study was to evaluate vitamin D status and its predictors in Slovenian premenopausal and postmenopausal women. A cross-sectional study was carried out between 1 March 2021 and 31 ...May 2021. A total of 319 healthy women from the Central Slovenian region aged between 44 and 65 were recruited; 176 were included in the final analysis. The vitamin D status was determined by measuring the total 25-Hydroxycholecalciferol (25(OH)D) concentration, vitamin D binding protein (DBP), and albumin and calculating the bioavailable 25(OH)D and free 25(OH)D. For the calculation of bioavailable and free 25(OH)D, we developed a new online calculator. The Endocrine Society’s thresholds for vitamin D deficiency and insufficiency were used; 29.0% of premenopausal and 24.4% of postmenopausal subjects were found to be vitamin D deficient (total 25(OH)D < 50 nmol/L); 76.8% of the premenopausal and 61.7% of postmenopausal subjects were found to have insufficient levels (total 25(OH)D < 75 nmol/L). Premenopausal women had 11.8% lower total 25(OH)D, 32.2% lower bioavailable 25(OH)D, and 25.2% higher DBP than postmenopausal women. The most important predictors of vitamin D status were vitamin D supplementation and time spent in the sun. Contrary to similar studies, the vitamin D status in Slovenian postmenopausal women was significantly better than in premenopausal women. In postmenopausal women, the measurement of free or bioavailable 25(OH)D instead of the total 25(OH)D could be advantageous.
Aerosols in caves are natural tracers and, together with climatic parameters, provide a detailed insight into atmospheric conditions, responses to climatic changes and anthropogenic influences in ...caves. Microbiological air monitoring in show caves is becoming increasingly useful to understand changes in cave ecosystems and to implement and review measures for sustainable cave use and tourism development. In 2017 and 2018, air along tourist trails in caves Postojnska jama and Škocjanske jame (Slovenia) was sampled before and after tourist visits. Samples were analysed using culture-dependent methods, flow cytometry, detection of β-D-glucan and lipopolysaccharide and compared with CO2 and temperature data to measure anthropogenic influences and seasonality on aerobiota. While the presence of tourists significantly increased concentrations of airborne microorganisms (p < 0.05), β-D-glucan and CO2 did not show such a trend and were more dependent on seasonal changes. Locally, concentrations of cultivable microorganisms above 1000 CFU/m3 were detected, which could have negative effects on the autochthonous microbiota and possibly on human health. A mixture of bacteria typically associated with humans was found in the air and identified with MALDI-TOF MS. Using MALDI-TOF MS, we achieved a 69.6% success rate in identification. Micrococcus luteus, Streptococcus mitis, Staphylococcus epidermidis and Moraxella spp. were recognized as good indicators of cave anthropisation.
Abstract
Introduction
Among physiotherapists, work-related musculoskeletal disorders (WMSDs) are the most common health problem. This study aimed to provide evidence for planning evidence-based ...health promotion programmes for ensuring and maintaining adequate physical fitness (PF) to decrease WMSDs among physiotherapists which would have started already during the study.
Methods
A cross-sectional study involved the participation of a total of 100 physiotherapy students and 62 physiotherapists. Observed variables were prevalence of WMSDs in the last 12 months, lasting >3 days during physiotherapeutic activities and five PF components: body composition, cardiorespiratory and muscle endurance, muscle strength, and flexibility. A chi-square test and binary logistic regression were used as the main analytical methods.
Results
Prevalence of WMSDs in physiotherapists was 63.9% (the most common locations: lower back, shoulders, neck), while in physiotherapy students it was 46.5% (the most common locations: lower back, neck, upper back) (p=0.031). Among the PF components, the results showed statistically significantly worse flexibility among students compared to physiotherapists (about two thirds of students had poor or very poor results of flexibility testing) (p=0.002) in comparison to physiotherapists. A statistically significant positive association between WMSDs and PF was observed only between knee pain and poor cardiorespiratory endurance (OR=4.03 with 95% CI 1.12-14.58; p=0.033).
Conclusion
The study showed poor flexibility among students indicating that it is necessary to direct them to perform activities that will increase the extensibility of muscles. The awareness of this problem should be increased. A specific role should be played by staff involved in clinical practice.
Objectives: The pandemic caused by the novel coronavirus (SARS-CoV-2) affected a disproportionately high percentage of healthcare workers (HCWs). The aim of the study was to assess the seroprevalence ...of SARS-CoV-2-specific IgG antibodies in nurses and clinicians working in 2 Slovenian regional hospitals, and to identify the factors associated with seropositivity. Material and Methods: The study was designed as a cross-sectional study. Clinicians and nurses were invited to participate in November-December 2020. The respondents (813, 65.8%) completed a questionnaire and consented to provide 10 ml of blood for determining the presence of SARS-CoV-2 IgG antibodies. Results: The authors observed a seroprevalence rate of 20.4%. The results of the univariate analysis proved that the age of a nurse or clinician was the factor most strongly associated with seropositivity--in fact, the youngest nurses and clinicians were 8.33 times more likely to be seropositive than those in the oldest age group (p = 0.041). Being in contact with a family/household member who was SARS-CoV-2-positive was also a very important factor. In the work-related factors group, being in the contact with a SARS-CoV-2-positive colleague (OR = 2.35, p = 0.026) or being in contact with a COVID-19 patient (OR = 1.96, p = 0.004) correlated with seropositivity. In the primary work location/department group, the only significant association appeared among those working in surgical, ENT or ophthalmology departments. The results of the multivariate analysis further supported the thesis that the age of nurses and clinicians was the factor most strongly associated with seropositivity. The youngest nurses and clinicians were 12.5 times more likely to be seropositive than those in the oldest age group (p = 0.024). Being in contact with a SARS-CoV-2-positive family/household member remained the second most important factor. Conclusions: A significant number of clinicians and nurses working in secondary healthcare were infected in the first 9 months of the pandemic.
