A survey on hydration and use of plastic water bottles among Italian health sector workers.

Background: Modena's Local Health Authority (AUSL) is a public service with more than 5,000 employees. In its facilities, drinking water is available as tap water. However, disposable plastic bottles are also widely used, thus increasing plastic waste. Study design and methods: In the present study, we aimed to investigate employees' drinking habits through an ad hoc 10-item online questionnaire, which was administered in spring 2023. Results: Of the 584 participants (10.8% response rate), 75% of workers reported drinking less than 1.5 liters of water per day. In addition, 74% of workers brought water from home, while 62% used disposable plastic containers bought in the workplace or outside. When asked if they would appreciate a water refilling station in the workplace, whether that would induce them to consume less plastic and to drink more water, 91%, 82%, and 72% of workers said "yes", respectively. By installing water coolers, the estimated mean number of plastic bottles spared every day at the AUSL would be about 6,000. Conclusions: Our data shed light on most employees' perceived need for alternative sources of drinking water, not only in order to drink more for health benefits, but also to reduce plastic usage in favor of reusable, more environmentally friendly materials.

Training in infection prevention and control: survey on the volume and on the learning demands of healthcare-associated infections control figures in the Emilia-Romagna Region (Northern Italy).

Background: In the context of Infections Prevention and Control activities, the training of healthcare-associated infection control figures is crucial; the COVID-19 pandemic further emphasized the necessity of ensuring a widespread and stable level of skills over time for such professionals. The present work aims to identify the number and training needs of the personnel working in the Emilia-Romagna Region's healthcare facilities as "healthcare-associated infection control figures". Methods: Data were collected through a survey created by experts from the Regional Group "Training in the prevention and control of antibiotic resistance". The questionnaire explored the number, professional and educational background, and training requirements of Healthcare-associated infections control figures in Emilia-Romagna. Results: With 73 figures dedicated to Healthcare-associated infections control, the Emilia-Romagna Region appears to be in line with the European standard ratio (1 professional every 125 beds). Professionals with a nursing background, over 50 years old and of female sex prevail in the group, while the training needs expressed include both theoretical and practical aspects. Conclusions: Healthcare assistants and nursing staff represent a fundamental resource for the implementation of infection prevention and control programs in our healthcare facilities; continuous, multidisciplinary and targeted training of these professionals is confirmed as necessary.

The key role of public health in renovating Italian biomedical doctoral programs.

Background: A key renovation of doctoral programs is currently ongoing in Italy. Public health and its competencies may play a pivotal role in high-level training to scientific research, including interdisciplinary and methodological abilities. Methods: As a case study, we used the ongoing renovation of the Clinical and Experimental Medicine doctoral program at the University of Modena and Reggio Emilia. We focused on how the program is designed to meet national requirements as well as students' needs, thus improving educational standards for scientific research in the biomedical field, and on the specific contribution of public health and epidemiology in such an effort. Results: The renovation process of doctoral programs in Italy, with specific reference to the biomedical field, focuses on epidemiologic-statistical methodology, ethics, language and communication skills, and open science from an interdisciplinary and international perspective. In the specific context of the doctoral program assessed in the study and from a broader perspective, public health appears to play a key role, taking advantage of most recent methodological advancements, and contributing to the renovation of the learning process and its systematic quality monitoring. Conclusions: From a comparative assessment of this case study and Italian legislation, the key role of public health has emerged in the renovation process of doctoral programs in the biomedical field.

Colorectal cancer risk and nitrate exposure through drinking water and diet.

Ingested nitrate leads to the endogenous synthesis of N-nitroso compounds (NOCs), animal carcinogens with limited human evidence. We aimed to evaluate the risk of colorectal cancer (CRC) associated with nitrate exposure in drinking water and diet. A case-control study in Spain and Italy during 2008-2013 was conducted. Hospital-based incident cases and population-based (Spain) or hospital-based (Italy) controls were interviewed on residential history, water consumption since age 18, and dietary information. Long-term waterborne ingested nitrate was derived from routine monitoring records, linked to subjects' residential histories and water consumption habits. Dietary nitrate intake was estimated from food frequency questionnaires and published food composition databases. Odd ratios (OR) were calculated using mixed models with area as random effect, adjusted for CRC risk factors and other covariables. Generalized additive models (GAMs) were used to analyze exposure-response relationships. Interaction with endogenous nitrosation factors and other covariables was also evaluated. In total 1,869 cases and 3,530 controls were analyzed. Average waterborne ingested nitrate ranged from 3.4 to 19.7 mg/day, among areas. OR (95% CIs) of CRC was 1.49 (1.24, 1.78) for >10 versus ≤5 mg/day, overall. Associations were larger among men versus women, and among subjects with high red meat intake. GAMs showed increasing exposure-response relationship among men. Animal-derived dietary nitrate was associated with rectal, but not with colon cancer risk. In conclusion, a positive association between CRC risk and waterborne ingested nitrate is suggested, mainly among subgroups with other risk factors. Heterogeneous effects of nitrate from different sources (water, animal and vegetables) warrant further research.

ECMO for pulmonary rescue in an adult with amiodarone-induced toxicity.

Amiodarone is a highly effective antiarrhythmic agent. Unfortunately amiodarone-induced pulmonary toxicity is described for medium-long term therapy. We describe a case of a 65-year-old man admitted to our department for breathlessness and with a history of recurrent episodes of atrial fibrillation for which he had been receiving amiodarone (200 mg/day) since 2008. Despite diuretic therapy, along with aspirin, statins and antibiotics the patient continued to complain of severe dyspnea and had a moderate fever. Thus, diagnostic hypotheses different from acute cardiac failure were considered, in particular non-cardiogenic causes of pulmonary infiltrates. Following suspicion of amiodarone-induced pulmonary toxicity, the drug was discontinued and corticosteroid therapy was initiated. Due to the deterioration of the clinical picture, we proceeded to intubation. After few hours from intubation we were forced to institute a veno-venous extracorporeal membrane oxygenation due to the worsening of pulmonary function. The patient's clinical condition improved which allowed us to remove the ECMO after 15 days of treatment. Indications for use of ECMO have expanded considerably. To our knowledge this is the first successful, reported article of a veno-venous ECMO used to treat amiodarone-induced toxicity in an adult. In patients with severe but potentially reversible pulmonary toxicity caused by amiodarone, extracorporeal life support can maintain pulmonary function and vital organ perfusion at the expense of low morbidity, while allowing time for drug clearance.

Prevention of healthcare-associated infections: knowledge among dental students in seven Italian universities.

BACKGROUND: Lack of knowledge is the major reason for non-compliance with correct healthcare-associated infections (HAI) prevention procedures. The aim of this study was to evaluate knowledge of the Dental School (DSS) and Dental Hygiene (DHS) students with regard to the prevention of HAI, as basic knowledge for improving and harmonizing the educational content in the different Italian Universities. METHODS: A cross-sectional study was carried out using an anonymous questionnaire that was completed by DSS (I, II, III, IV, and V year) in seven Universities and DHS (I, II, and III year) in three Universities. The questions dealt with three specific areas: healthcare-associated infections, standard precautions and hand hygiene. Factors associated with an unacceptable level of knowledge (score <17.5) were analyzed using a logistic regression model. A p value <0.05 was considered to be significant. RESULTS: Five hundred and four questionnaires were collected: 81.5% for DSS and 18.5% for DHS. Mean overall score (±DS) achieved by the total number of students was 18.2±2.93 on an overall perfect score of 25; 18.2±3.04 for DSS and 17.8±2.31 for DHS. Stratifying by area, the average score 2.7±1.07 (53%) for HAI, 10.3±1.61 (85.9%) for standard precautions, and 5.2±1.44 (64.8%) for hand hygiene was observed. A significantly different level of knowledge (p<0.001) between DSS and DHS was observed only for HAI (2.8±1.07 for DSS vs 2.1±0.96 for DHS). Significant differences among the academic years were found only for DSS concerning HAI and standard precautions. The logistic regression model showed that an age <23 years was a risk factor for lack of knowledge on HAI, but a protective factor for lack of knowledge about standard precautions and hand hygiene; attending DH degree course was associated with lack of knowledge on HAI. CONCLUSIONS: Although the overall score obtained both by DSS and DHS indicated an acceptable level of knowledge, lack of knowledge was highlighted, in particular, for hand hygiene. Therefore, it is necessary to implement and validate effective teaching models in undergraduate courses in order to provide the scientific basis and the theoretical and practical preparation for the prevention and control of HAI.

Canal shaping with WaveOne reciprocating files: influence of operator experience on instrument breakage and canal preparation time.

The aim of this study was to determine the fracture incidence of WaveOne Primary reciprocating files and the time required for shaping of curved canals based on the experience of the operator. A total of 109 mesiobuccal canals of permanent molars extracted with an angle of curvature of >25°-45° according to Schneider were randomly assigned to four groups. An experienced operator (endodontist) and an inexperienced operator (student) each shaped one of two groups: one with the instrument WaveOne Primary to WL and the other after creation of a glide path with PathFile 1, 2 and 3 at the WL. Any fractures or visible deformations of the instruments during the shaping phase and the effective time required to prepare the canals for each instrument were recorded. No visible deformation or fracture was observed. The experienced operator tended to finish their shape faster than the inexperienced operator regardless of the technique applied. For the inexperienced operator, the usage time with only WaveOne Primary was significantly lower when the canals were preliminarily instrumented with the PathFile than when these instruments were not used (average time, 22.03 vs. 36.22 s, respectively; p < 0.001). The experience of the operator did not influence fracture of the WaveOne Primary instruments. The time required to prepare the canals was instead inversely proportional to the experience of the operator. However, the creation of a glide path with PathFile instruments reduced the time required by the inexperienced operator to prepare the canal.

Differential efficacy of endodontic obturation procedures: an ex vivo study.

By means of a double-chamber model, different root canal filling materials and procedures were compared. Briefly, the root canals of single-rooted human teeth, extracted for periodontal reasons, were instrumented and obturated by gutta-percha/Pulp Canal Sealer EWT (PCS) or by Resilon, in association with different sealers (Real Seal, RelyX Unicem or Meta). Obturation was achieved by traditional continuous wave of condensation technique (TCWCT), a modified version of it (MCWCT), or single cone technique (SCT). The obturated roots, inserted in a double-chamber model, were sterilized by gamma irradiation. Next, Enterococcus faecalis was added to the upper chamber and the specimens were incubated at 37 °C for up to 120 days; the development of turbidity in the lower chambers' broths indicated bacterial leakage through the obturated root canals. The kinetics of leakage were analyzed in different groups by means of Kaplan-Meier statistics and compared by log-rank test. The results showed that root canals obturated with either gutta-percha/PCS using the MCWCT, Resilon/Real Seal SCT or Resilon/RelyX Unicem using the TCWCT displayed significantly better performance than the remaining groups (p < 0.01). Histological evaluation, performed to investigate microbial localization inside specimens, confirmed that this parameter varied according to the obturation procedures and materials employed. This ex vivo study indicates that gutta-percha/PCS, if used with the MCWCT, is as effective as Resilon when coupled to Real Seal with the SCT or, interestingly, to RelyX Unicem with the TCWCT. These data suggest that further improvement of the currently employed root canal filling procedures is achievable, depending on both the filling materials and the technique employed, thus encouraging clinical studies in this direction.

Conditioning factors in the spreading of Covid-19 - Does geography matter?

There is evidence in literature that the spread of COVID-19 can be influenced by various geographic factors, including territorial features, climate, population density, socioeconomic conditions, and mobility. The objective of the paper is to provide an updated literature review on geographical studies analysing the factors which influenced COVID-19 spreading. This literature review took into account not only the geographical aspects but also the COVID-19-related outcomes (infections and deaths) allowing to discern the potential influencing role of the geographic factors per type of outcome. A total of 112 scientific articles were selected, reviewed and categorized according to subject area, aim, country/region of study, considered geographic and COVID-19 variables, spatial and temporal units of analysis, methodologies, and main findings. Our literature review showed that territorial features may have played a role in determining the uneven geography of COVID-19; for instance, a certain agreement was found regarding the direct relationship between urbanization degree and COVID-19 infections. For what concerns climatic factors, temperature was the variable that correlated the best with COVID-19 infections. Together with climatic factors, socio-demographic ones were extensively taken into account. Most of the analysed studies agreed that population density and human mobility had a significant and direct relationship with COVID-19 infections and deaths. The analysis of the different approaches used to investigate the role of geographic factors in the spreading of the COVID-19 pandemic revealed that the significance/representativeness of the outputs is influenced by the scale considered due to the great spatial variability of geographic aspects. In fact, a more robust and significant association between geographic factors and COVID-19 was found by studies conducted at subnational or local scale rather than at country scale.

Effectiveness of the SARS-CoV-2 Vaccination in Preventing Severe Disease-Related Outcomes: A Population-Based Study in the Italian Province of Bolzano (South Tyrol).

Objective: To investigate the effectiveness of SARS-CoV2 vaccination in preventing ordinary or intensive care unit (ICU) admissions and deaths among cases registered during a variant transitional pandemic phase in the geographically and culturally unique territory of the Province of Bolzano (South Tyrol), an Italian region with low vaccination coverage. Methods: We collected data from 93,643 patients registered as positive for SARS-CoV-2 by health authorities during the winter of 2021-22. The data were analyzed retrospectively using descriptive statistics and multiple logistic regression. Results: 925 patients were hospitalized (0.99%), 89 (0.10%) were in intensive care, and 194 (0.21%) died. Vaccinated patients had a significantly lower risk of being hospitalized: adjusted Odds Ratio (aOR): 0.39; 95% CI: 0.33-0.46, ICU admission: aOR: 0.16; 95% CI: 0.09-0.29 and death: aOR: 0.41; 95% CI: 0.29-0.58. Similar risk reductions were also observed in booster-vaccinated patients, independent of sex, age, and predominant variant. Furthermore, the median length of stay (LoS) in the ICU was significantly longer for unvaccinated individuals compared to vaccinated subjects (9 vs. 6 days; p < 0.003). Conclusion: Primary series vaccination and ongoing campaign booster doses were effective in preventing all severe disease-related outcomes and in reducing ICU Length of Stay, even during a transitional pandemic phase and in a unique territorial context.

Investigating Eating Habits of Children Aged between 6 Months and 3 Years in the Provinces of Modena and Reggio Emilia: Is Our Kids' Diet Sustainable for Their and the Planet's Health?

A healthy and balanced diet is crucial for children's well-being and aids in preventing diet-related illnesses. Furthermore, unhealthy dietary habits indirectly impact children's health, as the food industry stands as one of the primary drivers of climate change. Evidence shows the Mediterranean diet is sustainable for both children's and the planet's health. The aim of this cross-sectional study was to evaluate the eating habits of children aged between 6 months and 3 years, in the province of Modena and Reggio Emilia, in Italy, along with their adherence to the guidelines for a healthy diet, and examine the role of pediatricians in promoting knowledge about nutrition and sustainability. In our sample (218 children), most children exceeded the recommended meat and cheese intake, while consuming insufficient amounts of vegetables, fruit, and legumes. Vegetable and fruit consumption declined with the increase in age category while eating sweets, soft drinks, and processed food increased. Incorporating school meals' data into this analysis, we observed a modification in dietary compliance, characterized by an increase in meat and cheese consumption, alongside improvements in the intake of vegetables, fruits, fish, eggs, and legumes. This study suggests that supporting an integrated approach that combines social and educational initiatives is crucial. Future research should prioritize fostering sustainable eating habits within communities to facilitate dietary habits' transformation and encourage healthier lifestyles.

Environmental, climatic, socio-economic factors and non-pharmacological interventions: A comprehensive four-domain risk assessment of COVID-19 hospitalization and death in Northern Italy.

INTRODUCTION: Up to now, studies on environmental, climatic, socio-economic factors, and non-pharmacological interventions (NPI) show diverse associations, often contrasting, with COVID-19 spread or severity. Most studies used large-scale, aggregated data, with limited adjustment for individual factors, most of them focused on viral spread than severe outcomes. Moreover, evidence simultaneously evaluating variables belonging to different exposure domains is scarce, and none analysing their collective impact on an individual level. METHODS: Our population-based retrospective cohort study aimed to assess the comprehensive role played by exposure variables belonging to four different domains, environmental, climatic, socio-economic, and non-pharmacological interventions (NPI), on individual COVID-19-related risk of hospitalization and death, analysing data from all patients (no. 68472) tested positive to a SARS-CoV-2 swab in Modena Province (Northern Italy) between February 2020 and August 2021. Using adjusted Cox proportional hazard models, we estimated the risk of severe COVID-19 outcomes, investigating dose-response relationships through restricted cubic spline modelling for hazard ratios. RESULTS: Several significant associations emerged: long-term exposure to air pollutants (NO2, PM10, PM2.5) was linked to hospitalization risk in a complex way and showed an increased risk for death; while humidity was inversely associated; temperature showed a U-shaped risk; wind speed showed a linear association with both outcomes. Precipitation increased hospitalization risk but decreased mortality. Socio-economic and NPI indices showed clear linear associations, respectively negative and positive, with both outcomes. CONCLUSIONS: Our findings offer insights for evidence-based policy decisions, improving precision healthcare practices, and safeguarding public health in future pandemics. Refinement of pandemic response plans by healthcare authorities could benefit significantly.

Collaborative outcomes study on health and functioning during infection times (COH-FIT): Insights on modifiable and non-modifiable risk and protective factors for wellbeing and mental health during the COVID-19 pandemic from multivariable and network analyses.

There is no multi-country/multi-language study testing a-priori multivariable associations between non-modifiable/modifiable factors and validated wellbeing/multidimensional mental health outcomes before/during the COVID-19 pandemic. Moreover, studies during COVID-19 pandemic generally do not report on representative/weighted non-probability samples. The Collaborative Outcomes study on Health and Functioning during Infection Times (COH-FIT) is a multi-country/multi-language survey conducting multivariable/LASSO-regularized regression models and network analyses to identify modifiable/non-modifiable factors associated with wellbeing (WHO-5)/composite psychopathology (P-score) change. It enrolled general population-representative/weighted-non-probability samples (26/04/2020-19/06/2022). Participants included 121,066 adults (age=42±15.9 years, females=64 %, representative sample=29 %) WHO-5/P-score worsened (SMD=0.53/SMD=0.74), especially initially during the pandemic. We identified 15 modifiable/nine non-modifiable risk and 13 modifiable/three non-modifiable protective factors for WHO-5, 16 modifiable/11 non-modifiable risk and 10 modifiable/six non-modifiable protective factors for P-score. The 12 shared risk/protective factors with highest centrality (network-analysis) were, for non-modifiable factors, country income, ethnicity, age, gender, education, mental disorder history, COVID-19-related restrictions, urbanicity, physical disorder history, household room numbers and green space, and socioeconomic status. For modifiable factors, we identified medications, learning, internet, pet-ownership, working and religion as coping strategies, plus pre-pandemic levels of stress, fear, TV, social media or reading time, and COVID-19 information. In multivariable models, for WHO-5, additional non-modifiable factors with |B|>1 were income loss, COVID-19 deaths. For modifiable factors we identified pre-pandemic levels of social functioning, hobbies, frustration and loneliness, and social interactions as coping strategy. For P-scores, additional non-modifiable/modifiable factors were income loss, pre-pandemic infection fear, and social interactions as coping strategy. COH-FIT identified vulnerable sub-populations and actionable individual/environmental factors to protect well-being/mental health during crisis times. Results inform public health policies, and clinical practice.

Global and risk-group stratified well-being and mental health during the COVID-19 pandemic in adults: Results from the international COH-FIT Study.

International studies measuring wellbeing/multidimensional mental health before/ during the COVID-19 pandemic, including representative samples for >2 years, identifying risk groups and coping strategies are lacking. COH-FIT is an online, international, anonymous survey measuring changes in well-being (WHO-5) and a composite psychopathology P-score, and their associations with COVID-19 deaths/restrictions, 12 a-priori defined risk individual/cumulative factors, and coping strategies during COVID-19 pandemic (26/04/2020-26/06/2022) in 30 languages (representative, weighted non-representative, adults). T-test, χ2, penalized cubic splines, linear regression, correlation analyses were conducted. Analyzing 121,066/142,364 initiated surveys, WHO-5/P-score worsened intra-pandemic by 11.1±21.1/13.2±17.9 points (effect size d=0.50/0.60) (comparable results in representative/weighted non-probability samples). Persons with WHO-5 scores indicative of depression screening (<50, 13% to 32%) and major depression (<29, 3% to 12%) significantly increased. WHO-5 worsened from those with mental disorders, female sex, COVID-19-related loss, low-income country location, physical disorders, healthcare worker occupations, large city location, COVID-19 infection, unemployment, first-generation immigration, to age=18-29 with a cumulative effect. Similar findings emerged for P-score. Changes were significantly but minimally related to COVID-19 deaths, returning to near-pre-pandemic values after >2 years. The most subjectively effective coping strategies were exercise and walking, internet use, social contacts. Identified risk groups, coping strategies and outcome trajectories can inform global public health strategies.

Feasibility and safety of endovascular treatment for chronic cerebrospinal venous insufficiency in patients with multiple sclerosis.

OBJECTIVE: Chronic cerebrospinal venous insufficiency (CCSVI) is a recently discovered syndrome mainly due to stenoses of internal jugular (IJV) and/or azygos (AZ) veins. The present study retrospectively evaluates the feasibility and safety of endovascular treatment for CCSVI in a cohort of patients with multiple sclerosis (MS). METHODS: From September 2010 to October 2012, 1202 consecutive patients were admitted to undergo phlebograpy ± endovascular treatment for CCSVI. All the patients had previously been found positive at color Doppler sonography (CDS) for at least two Zamboni criteria for CCSVI and had a neurologist-confirmed diagnosis of MS. Only symptomatic MS were considered for treatment. Percutaneous transluminal angioplasty was carried out as an outpatient procedure at two different institutes. Primary procedures, regarded as the first balloon angioplasty ever performed for CCSVI, and secondary (reintervention) procedures, regarded as interventions performed after venous disease recurrence, were carried out in 86.5% (1037 of 1199) and 13.5% (162 of 1199) of patients, respectively. Procedural success and complications within 30 days were recorded. RESULTS: Phlebography followed by endovascular recanalization was carried out in 1999 patients consisting of 1219 interventions. Balloon angioplasty alone was performed in 1205 out of 1219 (98.9%) procedures, whereas additional stent placement was required in the remaining 14 procedures (1.1%) following unsuccessful attempts at AZ dilatation. No stents were ever implanted in the IJV. The feasibility rate was as high as 99.2% (1209 interventions). Major complications included one (0.1%) AZ rupture occurring during balloon dilatation and requiring blood transfusion, one (0.1%) severe bleeding in the groin requiring open surgery, two (0.2%) surgical openings of the common femoral vein to remove balloon fragments, and three (0.2%) left IJV thromboses. The overall major and minor complication rates at 30 days were 0.6% and 2.5%, respectively. CONCLUSIONS: Endovascular treatment for CCSVI appears feasible and safe. However, a proper learning curve can dramatically lower the rate of adverse events. In our experience, the vast majority of complications occurred in the first 400 cases performed.

[Home management of Covid-19 pneumonia in the early phases of the pandemic: analysis of real-life data of General Practitioners in the Province of Modena from the MAGMA study.] / Gestione domiciliare dei pazienti con polmonite da Covid-19 nelle fasi precoci della pandemia: analisi dei dati real-life della Medicina Generale della Provincia di Modena dallo studio MAGMA.

Primary care management of Covid-19 pneumonia in the Province of Modena in the early phases of the pandemic: data integration from MAGMA study. Retrospective study on patients affected of Covid-19 and followed by General Practitioner from March 2020 to April 2021. 5340 patients were studied, 27% of them developed pneumoniae. Among these, most of them were managed entirely at home with an elevated intensity of care. Daily remote monitoring and home visits, together with a personalized pharmacological treatment, especially for the most severe forms, appeared to be the most effective interventions in reducing hospitalizations.

Perinatal and postnatal exposure to phthalates and early neurodevelopment at 6 months in healthy infants born at term.

Background: Phthalates are non-persistent chemicals largely used as plasticizers and considered ubiquitous pollutants with endocrine disrupting activity. The exposure during sensible temporal windows as pregnancy and early childhood, may influence physiological neurodevelopment. Aims and Scope: The aim of this study is to analyze the relationship between the urinary levels of phthalate metabolites in newborn and infants and the global development measured by the Griffiths Scales of Children Development (GSCD) at six months. Methods: Longitudinal cohort study in healthy Italian term newborn and their mothers from birth to the first 6 months of life. Urine samples were collected at respectively 0 (T0), 3 (T3), 6 (T6) months, and around the delivery for mothers. Urine samples were analyzed for a total of 7 major phthalate metabolites of 5 of the most commonly used phthalates. At six months of age a global child development assessment using the third edition of the Griffith Scales of Child Development (GSCD III) was performed in 104 participants. Results: In a total of 387 urine samples, the seven metabolites analyzed appeared widespread and were detected in most of the urine samples collected at any time of sampling (66-100%). At six months most of the Developmental Quotients (DQs) falls in average range, except for the subscale B, which presents a DQ median score of 87 (85-95). Adjusted linear regressions between DQs and urinary phthalate metabolite concentrations in mothers at T0 and in infants at T0, T3 and T6 identified several negative associations both for infants' and mothers especially for DEHP and MBzP. Moreover, once stratified by children's sex, negative associations were found in boys while positive in girls. Conclusions: Phthalates exposure is widespread, especially for not regulated compounds. Urinary phthalate metabolites were found to be associated to GSCD III scores, showing inverse association with higher phthalate levels related to lower development scores. Our data suggested differences related to the child's sex.

The effects of primary care monitoring strategies on COVID-19 related hospitalisation and mortality: a retrospective electronic medical records review in a northern Italian province, the MAGMA study.

BACKGROUND: Most symptomatic SARS-CoV-2 infections produce mild to moderate symptoms. Although most patients are managed in the outpatient setting, little is known about the effect of general practitioners' (GP) management strategies on the outcomes of COVID-19 outpatients in Italy. OBJECTIVES: Describe the management of Italian GPs of SARS-CoV-2 infected adult patients and explore whether GP active care and monitoring are associated with reducing hospitalisation and death. METHODS: Retrospective observational study of SARS-CoV-2 infected adult outpatients managed by GPs in Modena (Italy) from March 2020 to April 2021. Information on management and monitoring strategies, patients' socio-demographic characteristics, comorbidities, and outcomes (hospitalisation and death due to COVID-19) were retrieved through an electronic medical record review and analysed descriptively and through multiple logistic regression. RESULTS: Out of the 5340 patients from 46 GPs included in the study, 3014 (56%) received remote monitoring, and 840 (16%) had at least one home visit. More than 85% of severe or critical patients were actively monitored (73% daily) and 52% were visited at home. Changes over time in patients' therapeutic management were observed in concordance with the guidelines' release. Active daily remote monitoring and home visits were strongly associated with reduced hospitalisation rate (OR 0.52, 95% CI 0.33-0.80 and OR 0.50, 95% CI 0.33-0.78 respectively). CONCLUSION: GPs effectively managed an increasing number of outpatients during the first waves of the pandemic. Active monitoring and home visits were associated with reduced hospitalisation in COVID-19 outpatients.

Occurrence and toxicity of disinfection byproducts in European drinking waters in relation with the HIWATE epidemiology study.

The HIWATE (Health Impacts of long-term exposure to disinfection byproducts in drinking WATEr) project was a systematic analysis that combined the epidemiology on adverse pregnancy outcomes and other health effects with long-term exposure to low levels of drinking water disinfection byproducts (DBPs) in the European Union. The present study focused on the relationship of the occurrence and concentration of DBPs with in vitro mammalian cell toxicity. Eleven drinking water samples were collected from five European countries. Each sampling location corresponded with an epidemiological study for the HIWATE program. Over 90 DBPs were identified; the range in the number of DBPs and their levels reflected the diverse collection sites, different disinfection processes, and the different characteristics of the source waters. For each sampling site, chronic mammalian cell cytotoxicity correlated highly with the numbers of DBPs identified and the levels of DBP chemical classes. Although there was a clear difference in the genotoxic responses among the drinking waters, these data did not correlate as well with the chemical analyses. Thus, the agents responsible for the genomic DNA damage observed in the HIWATE samples may be due to unresolved associations of combinations of identified DBPs, unknown emerging DBPs that were not identified, or other toxic water contaminants. This study represents the first to integrate quantitative in vitro toxicological data with analytical chemistry and human epidemiologic outcomes for drinking water DBPs.

Trihalomethanes, chlorite, chlorate in drinking water and risk of congenital anomalies: a population-based case-control study in Northern Italy.

BACKGROUND: Epidemiological evidence of an association between disinfection by-products (DBPs) exposure via drinking water and reproductive outcomes is still inconclusive. OBJECTIVE: The aim of this study was to investigate the association between trihalomethanes (THMs), chlorite and chlorate exposure and congenital anomalies. METHODS: A case-control study was carried out in Emilia-Romagna Region (Italy). Data on 1917 different congenital anomalies (neural tube, cardiac, diaphragm and abdominal wall, oesophagus, cleft lip and palate, respiratory, urinary tract and chromosomal anomalies) observed in the period 2002-2005 were extracted from the Regional Malformation Registry. Four controls (newborns without anomalies) were randomly selected form the Regional Birth Register and frequency matched to cases according to pregnancy period. The network supplying water during the first trimester of pregnancy was identified on the basis of mother's address: DBPs data, technical and structural information were linked to each subject. RESULTS: Overall, THMs exposure was very low (mean: 3.8±3.6 µg/l), and no risk excess was observed. Chlorite and chlorate values were fairly high (mean: 427±184 µg/l and 283±79 µg/l, respectively). Women exposed to chlorite level >700 µg/l were at higher risk of newborns with renal defects (OR: 3.30; 95% IC: 1.35-8.09), abdominal wall defects (OR: 6.88; 95% IC: 1.67-28.33) and cleft palate (OR: 4.1; 95% IC: 0.98-16.8); women exposed to chlorate level >200 µg/l were at higher risk of newborns with obstructive urinary defects (OR: 2.88; 95% IC: 1.09-7.63), cleft palate (OR: 9.60; 95% IC:1.04-88.9) and spina bifida (OR: 4.94; 95% IC:1.10-22). CONCLUSIONS: This was the first study showing an excess risk of different congenital anomalies related to chlorite and chlorate exposure via drinking water: further research is needed to confirm the observed relationships in large datasets, specifically for chlorate, an unregulated DBP.
