The interplay of sex/gender and migration: implications for health and healthcare access.

This intervention explores the intricate relationship among sex, gender, migratory status, and health outcomes in migrant populations. It emphasizes the distinction between sex (biological characteristics) and gender (socially constructed roles), highlighting how they intersect throughout the migration journey. The impact of gender dynamics on migration decisions, experiences, and outcomes is examined, with specific attention to sex/gender differences in the health and lifestyles of immigrant populations. Furthermore, it underscores how sex and gender disparities may affect access to healthcare. The importance of sex- and gender-inclusive healthcare services and cultural sensitivity in addressing these disparities is emphasized. Additionally, the intervention calls for research that considers diverse gender identities and country-specific factors. Ultimately, it asserts the need for sex- and gender-sensitive policies, collaborative efforts, and tailored interventions to promote health equity, gender equality, and human rights in migrant populations, aligning with global policy goals.

The association between perfluoroalkyl substances and lipid profile in exposed pregnant women in the Veneto region, Italy.

BACKGROUND: Residents of a large area of North-Eastern Italy were exposed for decades to high concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS) via drinking water. Serum PFAS levels have been consistently associated with elevated serum lipids, but few studies have been conducted among pregnant women, and none has stratified analyses by trimester of gestation. Elevated serum lipid levels during pregnancy can have both immediate and long-lasting effects on pregnant women and the developing fetus. We evaluated the association between perfluorooctane sulfonate (PFOS), perfluorooctanoic acid (PFOA), and perfluoro-hexanesulfonate (PFHxS) levels in relation to lipid profiles in highly-exposed pregnant women. METHODS: A cross-sectional analysis was conducted in 319 pregnant women (age 14-48 years) enrolled in the Regional health surveillance program. Non-fasting blood samples were obtained in any trimester of pregnancy and analyzed for PFOA, PFOS and PFHxS, total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C). Low-density lipoprotein cholesterol (LDL-C) was calculated. The associations between ln-transformed PFAS (and categorized into quartiles) and lipids were assessed using generalized additive models. Analyses were adjusted for potential confounders and stratified according to pregnancy trimester. RESULTS: The geometric means of PFOA, PFOS and PFHxS were 14.78 ng/mL, 2.67 ng/mL and 1.89 ng/mL, respectively. The plasma levels of TC, HDL-C and LDL-C increased steadily throughout the trimesters. In the 1st trimester, PFOS was positively associated with TC and PFHxS with HDL-C. In the 3rd trimester, instead, an inverse relationship was seen between PFOA and PFHxS and both TC and LDL-C. CONCLUSIONS: Results suggest the associations between PFAS concentrations and lipid profiles in pregnant women might differ by trimesters of pregnancy. In the first trimester, patterns are similar to those of non-pregnant women, while they differ late in pregnancy. Different independent behavior of PFAS and lipid levels throughout the pregnancy might explain our observations. These findings support the ubiquitous exposure to PFAS and possible influence on lipid metabolisms during pregnancy and suggest a careful evaluation of the timing of PFAS measurement, when examining effects of PFAS during pregnancy on gestational outcomes related to serum lipids amounts.

Avoidable hospitalisation for diabetes mellitus among immigrants and natives: Results from the Italian Network for Longitudinal Metropolitan Studies.

BACKGROUND AND AIMS: Italy has experienced a relevant increase in migration inflow over the last 20 years. Although the Italian Health Service is widely accessible, immigrants can face many barriers that limit their use of health services. Diabetes mellitus (DM) has a different prevalence across ethnic groups, but studies focusing on DM care among immigrants in Europe are scarce. This study aimed to compare the rates of avoidable hospitalisation (AH) between native and immigrant adults in Italy. METHODS AND RESULTS: A multi-centre open cohort study including all 18- to 64-year-old residents in Turin, Venice, Reggio-Emilia, Modena, Bologna and Rome between 01/01/2001 and 31/12/2013-14 was conducted. Italian citizens were compared with immigrants from high migratory pressure countries who were further divided by their area of origin. We calculated age-, sex- and calendar year-adjusted rate ratios (RRs) and 95% confidence intervals (95% CIs) of AH for DM by citizenship using negative binomial regression models. The RRs were summarized using a random effects meta-analysis. The results showed higher AH rates among immigrant males (RR: 1.63, 95% CI: 1.16-2.23), whereas no significant difference was found for females (RR: 1.14, 95% CI: 0.65-1.99). Immigrants from Asia and Africa showed a higher risk than Italians, whereas those from Central-Eastern Europe and Central-Southern America did not show any increased risk. CONCLUSION: Adult male immigrants were at higher risk of experiencing AH for DM than Italians, with differences by area of origin, suggesting that they may experience lower access to and lower quality of primary care for DM. These services should be improved to reduce disparities.

Potentially avoidable hospitalization for asthma in children and adolescents by migrant status: results from the Italian Network for Longitudinal Metropolitan Studies.

BACKGROUND: Global migration toward Europe is increasing. Providing health assistance to migrants is challenging because numerous barriers limit their accessibility to health services. Migrants may be at a greater risk of developing asthma and receiving lower quality healthcare assistance than non-migrants. We aim to investigate whether immigrants as children and adolescents have higher rates of potentially avoidable hospitalization (PAH) for asthma compared to Italians. METHODS: We performed a retrospective longitudinal study using six cohorts of 2-17-year-old residents in North and Central Italy from 01/01/2001 to 31/12/2014 (N = 1,256,826). We linked asthma hospital discharges to individuals using anonymized keys. We estimated cohort-specific age and calendar-year-adjusted asthma PAH rate ratios (HRRs) and 95% confidence intervals (95%CIs) among immigrants compared to Italians. We applied a two-stage random effect model to estimate asthma PAH meta-analytic rate ratios (MHRRs). We analyzed data by gender and geographical area of origin countries. RESULTS: Three thousand three hundred four and 471 discharges for asthma PAH occurred among Italians and immigrants, respectively. Compared to Italians, the asthma PAH cohort-specific rate was higher for immigrant males in Bologna (HRR:2.42; 95%CI:1.53-3.81) and Roma (1.22; 1.02-1.45), and for females in Torino (1.56; 1.10-2.20) and Roma (1.82; 1.50-2.20). Asthma PAH MHRRs were higher only among immigrant females (MHRRs:1.48; 95%CI:1.18-1.87). MHRRs by area of origin were 63 to 113% higher among immigrants, except for Central-Eastern Europeans (0.80; 0.65-0.98). CONCLUSION: The asthma PAH meta-analytic rate was higher among female children and adolescent immigrants compared to Italians, with heterogeneity among cohorts showing higher cohort-specific PAH also among males, with some differences by origin country. Access to primary care for children and adolescent immigrants should be improved and immigrants should be considered at risk of severe asthma outcomes and consequently targeted by clinicians.

A Systematic Review of Case-Identification Algorithms Based on Italian Healthcare Administrative Databases for Two Relevant Diseases of the Endocrine System: Diabetes Mellitus and Thyroid Disorders.

BACKGROUND: diabetes mellitus (DM) and thyroid disorders (TDs) are two of the most prevalent and relevant endocrine disorders worldwide, and determining their occurrence and their follow-up pathways is essential. In Italy, due to the presence of a universal health care system, administrative data can be effectively used to determine these measurements. DM is an ideal model for surveillance with administrative data, due to its specific pharmacologic treatment, high rate of hospitalization, and specific care units. The identification of TDs, conversely, is more challenging: they are less frequently managed in a hospital setting, and even if the treatment is highly specific, subclinical forms often do not need any pharmacological treatment. OBJECTIVES: to identify and to describe all DM and TD caseidentification algorithms by means of Italian Healthcare Administrative Databases (HADs), through the review of papers published in the past 10 years. METHODS: this study is part of a project that systematically reviewed case-identification algorithms for 18 acute and chronic conditions by means of HADs in Italy. PubMed was searched for original articles, published between 2007 and 2017, in Italian or English. The search string consisted of a combination of free text and MeSH terms with a common part that focused on HADs and a disease-specific part. All identified papers were screened by two independent reviewers. Pertinent papers were classified according to the objective for which the algorithm had been used, and only articles that used algorithms for "primary objectives" (I disease occurrence; II population/cohort selection; III outcome identification) were considered for algorithm extraction. The HADs used (hospital discharge records, drug prescriptions, etc.), ICD-9 and ICD-10 codes, ATC classification of drugs, follow-back periods, and age ranges applied by the algorithms have been reported. Further information on specific objective(s), accuracy measures, sensitivity analyses and the contribution of each HAD, have also been recorded. Algorithms were divided between those identifying type 2/not specified DM and type 1 DM, and those created to identify hypo- and hyperthyroidism. RESULTS: of the 780 articles identified for DM, 77 were included and a further 14 papers were added by screening the references. For TD, 65 articles were identified through the search string and 5 of them were included. Of the selected articles, 64% and 80% were published after 2014 for DM and TD, respectively, and 33% (for DM) and 20% (for TD) used multicentric national or international data. Forty original algorithms for DM (29 for type 2 DM/not-specified DM, and 11 for type 1 DM) and 9 for TD (6 for hypo- and 3 for hyperthyroidism) were extracted. In 6 algorithms, specific selections were made so as not to include gestational diabetes. With regard to type 2 DM, the most commonly used sources were the drug prescription database (DPD, 27 cases), hospital discharge record database (HDD, 23 cases), and exemption from healthcare co-payment database (ECD, 19 cases). Other sources were the ambulatory care services database (ACD), birth register, and mortality record database (MRD). Among the 11 algorithms to identify type 1 DM, 9 used DPD, 7 ECD, and 6 HDD; in one case ACD codes were added, and all 11 algorithms but one was applied to a population of young people (always <35 years old). With regard to TDs, 2 algorithms from one paper for hypo and hyperthyroidism relied on DPD as the only source, the other 7 original algorithms combined DPD with HDD (5 cases), ECD (3 cases), and ACD (1 case). One paper identified autoimmune/iodine deficiency hypothyroidism by subtracting iatrogenic hypothyroidism cases (identified through records of previous procedures from HDD and ACD) from the whole hypothyroid population (identified through DPD). External validation was performed for two algorithms for DM and none for TD. The first algorithm for DM was obtained through HDD only and its sensitivity ranged from 61% to 70%, the second had a sensitivity of 71%. CONCLUSION: Italian literature on the use of administrative healthcare data for case identification of diabetes is vast; the proposed algorithms are quite similar to one another, and the differences between them are rarely accompanied by clinical justification. On the contrary, the literature concerning thyroid disorders is relatively poor. Further validations of the proposed algorithms, as well as their further implementation, are needed.

[Immigrants' health and socioeconomic inequalities of overall population residing in Italy evaluated through the Italian network of Longitudinal Metropolitan Studies]. / Salute degli immigrati e disuguaglianze socioeconomiche nella popolazione residente in Italia valutate attraverso la rete degli Studi Longitudinali Metropolitani.

INTRODUCTION: Describing and monitoring socioeconomic inequalities in health are the prerequisite for planning equity policies. In Italy, some cities have integrated personal information from the municipal registries with Census data and with data from healthcare information systems to set up Longitudinal Metropolitan Studies (LMS). Under the coordination of the Italian National Institute for Health, Migration, and Poverty (NIHMP), six cities in the LMS network have contributed to the present monograph: Turin, Venice, Reggio Emilia, Modena, Bologna, and Rome. MORTALITY RESULTS. Significant socioeconomic differences by level of education were seen in all the participating centres. People who live alone or in single-parent households are more likely to die, as are those living in a substandard dwelling. Immigrants resident in the six cities included in the study showed lower all-cause mortality than Italians (males: MRR 0.83; 95%CI 0.78-0.90 - females: MRR 0.70; 95%CI 0.64-0.77). Sub-Saharan Africans experienced a significant higher mortality than Italians (males: MRR 1.33; 95%CI 1.12-1.59 - females: MMR 1.69; 95%CI 1.31-2.17). Immigrants had a neonatal and post-neonatal mortality risk about 1.5 times higher than Italians (neonatal: OR 1.71; 95%CI 1.22-2.39 - post-neonatal: OR 1.63; 95%CI 1.03-2.57). A difference between Italians and immigrants was also observed for mortality in children aged 1-4 years, though less marked (OR 1.24; 95%CI 0.73-2.11). Excesses concerned particularly immigrants from North Africa and from sub-Saharan Africa as well as those residing in Italy for >5 years. HOSPITALISATION RESULTS. Hospitalisation rates are lower for immigrants than for Italians, except when due to infectious diseases, blood disorders, and, among women, for reasons linked to pregnancy and childbirth. Avoidable hospitalisation rates of adults from low migratory pressure Countries are lower than or equal to those of Italians. On the contrary, adults from low migratory pressure Countries show higher avoidable hospitalisation rates compared to Italians in every cohort, with the exception of Rome (RR 0.81; 95%CI 0.78-0.85), with RR ranging from 1.08 (95%CI 0.96-1.22) in Venice to 1.64 (95%CI 1.47-1.83) in Modena. CONCLUSIONS: Maternal and child health is the most critical area of health for immigrant population. Considering the importance that the issue of health equity has taken on in the political agenda, the data presented in this volume are a great asset, particularly in light of the long recession and the social crisis that have impacted the Country.

A Systematic Review of Case-Identification Algorithms for 18 Conditions Based on Italian Healthcare Administrative Databases: A Study Protocol.

BACKGROUND: there has been a long-standing, consistent use worldwide of Healthcare Administrative Databases (HADs) for epidemiological purposes, especially to identify acute and chronic health conditions. These databases are able to reflect health-related conditions at a population level through disease-specific case-identification algorithms that combine information coded in multiple HADs. In Italy, in the past 10 years, HAD-based case-identification algorithms have experienced a constant increase, with a significant extension of the spectrum of identifiable diseases. Besides estimating incidence and/or prevalence of diseases, these algorithms have been used to enroll cohorts, monitor quality of care, assess the effect of environmental exposure, and identify health outcomes in analytic studies. Despite the rapid increase in the use of case-identification algorithms, information on their accuracy and misclassification rate is currently unavailable for most conditions. OBJECTIVES: to define a protocol to systematically review algorithms used in Italy in the past 10 years for the identification of several chronic and acute diseases, providing an accessible overview to future users in the Italian and international context. METHODS: PubMed will be searched for original research articles, published between 2007 and 2017, in Italian or English. The search string consists of a combination of free text and MeSH terms with a common part on HADs and a disease-specific part. All identified papers will be screened for eligibility by two independent reviewers. All articles that used/defined an algorithm for the identification of each disease of interest using Italian HADs will be included. Algorithms with exclusive use of death certificates, pathology register, general practitioner or pediatrician data will be excluded. Pertinent papers will be classified according to the objective for which the algorithm was used, and only articles that used algorithms with "primary objectives" (I disease occurrence; II population/cohort selection; III outcome identification) will be considered for algorithm extraction. The HADs used (hospital discharge records, drug prescriptions, etc.), ICD-9 and ICD-10 codes, ATC classification of drugs, follow-back periods, and age ranges applied by the algorithms will be collected. Further information on specific accuracy measures from external validations, sensitivity analyses, and the contribution of each source will be recorded. This protocol will be applied for 16 different systematic reviews concerning eighteen diseases (Hypothyroidism, Hyperthyroidism, Diabetes mellitus, Type 1 diabetes mellitus, Acute myocardial infarction, Ischemic heart disease, Stroke, Hypertension, Heart failure, Congenital heart anomalies, Parkinson's disease, Multiple sclerosis, Epilepsy, Chronic obstructive pulmonary disease, Asthma, Inflammatory bowel disease, Celiac disease, Chronic kidney failure). CONCLUSION: this protocol defines a standardized approach to extensively examine and compare all experiences of case identification algorithms in Italy, on the 18 abovementioned diseases. The methodology proposed may be applied to other systematic reviews concerning diseases not included in this project, as well as other settings, including international ones. Considering the increasing availability of healthcare data, developing standard criteria to describe and update characteristics of published algorithms would be of great use to enhance awareness in the choice of algorithms and provide a greater comparability of results.

Avoidable hospitalization among migrants and ethnic minority groups: a systematic review.

Background: The numbers of migrants living in Europe are growing rapidly, and has become essential to assess their access to primary health care (PHC). Avoidable Hospitalization (AH) rates can reflect differences across migrant and ethnic minority groups in the performance of PHC. We aimed to conduct a systematic review of all published studies on AH comparing separately migrants with natives or different racial/ethnic groups, in Europe and elsewhere. Methods: We ran a systematic search for original articles indexed in primary electronic databases on AH among migrants or ethnic minorities. Studies presenting AH rates and/or rate ratios between at least two different ethnic minority groups or between migrants and natives were included. Results: Of the 35 papers considered in the review, 28 (80%) were conducted in the United States, 4 in New Zealand, 2 in Australia, 1 in Singapore, and none in Europe. Most of the studies (91%) used a cross-sectional design. The exposure variable was defined in almost all articles by ethnicity, race, or a combination of the two; country of birth was only used in one Australian study. Most of the studies found significant differences in overall AH rates, with minorities (mainly Black and Hispanics) showing higher rates than non-Hispanic Whites. Conclusions: AH has been used, mostly in the US, to compare different racial/ethnic groups, while it has never been used in Europe to assess migrants' access to PHC. Studies comparing AH rates between migrants and natives in European settings can be helpful in filling this lack of evidence.

[Contribution of amenable mortality to the decrease of overall mortality in Piedmont Region (Northern Italy), 1980-2011]. / Il contributo della mortalità amenable alla diminuzione della mortalità generale in Piemonte dal 1980 al 2011.

OBJECTIVES: to describe overall and amenable mortality trends over the last 30 years in the Local Health Authorities (LHAs) of Piedmont Region (Northern Italy). By comparing these trends, it is possible to analyse intraregional variability in the performance of the healthcare system. DESIGN: descriptive study. SETTING AND PARTICIPANTS: mortality data from the Italian National Institute of Statistics (Istat) for the population between 0 and 74 years resident in Piedmont Region for the period 1980-2011. MAIN OUTCOME MEASURES: overall and amenable age-standardised death rates, by gender and health unit; ratio of the differences in amenable and in all-cause mortality (standardised rate difference - SRD: SRDamenable/SRDall-cause) over the observation period. RESULTS: between 1980 and 2011, overall mortality in Piedmont has decreased from 425.8 x100,000 to 205.5 x100.000 among women, and from 891.6 x100,000 to 390.7 x100,000 among men. The rate of amenable mortality on overall mortality decreased from 40% to 32% among women, and from 33% to 21% among men. Furthermore, amenable mortality contributed to 48% of the overall mortality reduction among women and to 35% among men. Regional results show heterogeneity between health units. This heterogeneity decreased over the three decades and was higher in men than in women. CONCLUSION: although Piedmont is one of the Italian Regions with the highest amenable mortality rate, a considerable decrease of its contribution to the overall mortality was seen in the last three decades. This improvement was not equally among LHAs, and substantial intraregional differences are still present, probably due to different timing and way of introduction of healthcare innovations for prevention and care for amenable to healthcare diseases. The proportion of amenable mortality on overall mortality is much higher among women than men, and it probably depends on the diseases considered in the definition itself.

Migrant status disparities in blood pressure: a multiple mediation analysis of modifiable factors.

BACKGROUND: We examined differences in blood pressure (BP) levels between first-generation immigrants and natives in adult residents in Northeast Italy, and investigated the role of lifestyle behaviors, body mass index (BMI), and education as potentially modifiable mediating factors. METHODS: We included 20-69-year-old participants from the Health Surveillance Program of the Veneto Region (n = 37,710). Immigrants born in a high migratory pressure country (HMPC) were further grouped into geographical macro-areas. The outcomes were systolic BP (SBP) and hypertension. Multiple mediation analyses were performed to determine the contribution of each mediator of the SBP/migrant status association. RESULTS: Of the 37,380 subjects included, 8.7% were born in an HMPC. BMI, education, alcohol, sweets and meat consumption were included as potential mediators. A small advantage in SBP was seen for immigrants compared to natives (ß = - 0.71,95%CI - 1.30; - 0.10). The direct effect (net of the covariates) of immigrant status on SBP was a reduction of 1.62 mmHg (95%CI - 2.25; - 0.98). BMI played the highest suppressive role (ß = 1.14,95%CI 0.99; 1.35), followed by education. Alcohol consumption amplified the health advantage of immigrants. The suppressing effect of BMI was particularly evident among women and North Africans compared to natives. Similar results were seen for hypertension rates. CONCLUSIONS: Although causation cannot be proven given the cross-sectional design, our findings identify BMI as the most effective target to preserve the health advantage of immigrants with respect to BP levels.

Adherence to Cervical Cancer Screening Programs in Migrant Populations: A Systematic Review and Meta-Analysis.

Organized cervical cancer screening programs to promote the early identification of precancerous lesions have proven to be effective in decreasing the burden associated with cervical cancer, but knowledge regarding screening adherence among migrant women compared to that of native women has not been summarized. A systematic search of the literature on PubMed, Scopus and Embase led to the identification of 772 papers that were published up to July 2022 and reported population-based data regarding adherence to cervical screening. The screening participation rates among migrant women, compared to native women, were pooled using a random-effects meta-analysis. A total of 18 papers were included in the review, with most of them being conducted in Europe (83.3%). Overall, migrants showed a significantly lower participation rate compared to native women (OR for screening adherence: 0.54, 95% CI = 0.42-0.70). This discrepancy was especially evident for migrant women from North Africa and Sub-Saharan Africa (OR = 0.47, 95% CI = 0.35-0.63, and OR = 0.35, 95% CI = 0.24-0.49, respectively). The results of this systematic review emphasize the importance of increasing cervical cancer screening adherence among migrant women. A significant heterogeneity in screening adherence was observed based on the country of origin. Interventions aimed at reducing the disparities in screening participation should specifically consider how to improve the recruitment of migrant women.

Adult first-generation immigrants and cardiovascular risk factors in the Veneto Region, Northeast Italy.

Introduction: The health condition of immigrants traditionally follows a transition from a low disease occurrence to the epidemiological profile of the deprived groups in the host country. In the Europe, studies examining differences in biochemical and clinical outcomes among immigrants and natives are lacking. We examined differences in cardiovascular risk factors between first-generation immigrants and Italians, and how migration pattern variables could affect health outcomes. Material and methods: We included participants between 20 and 69 years recruited from a Health Surveillance Program of the Veneto Region. Blood pressure (BP), total cholesterol (TC) and LDL cholesterol levels were measured. Immigrant status was defined by being born in a high migratory pressure country (HMPC) and subdivided by geographical macro-areas. We used generalized linear regression models to investigate differences between these outcomes among immigrants compared to native-born, adjusting for age, sex, education, BMI, alcohol consumption, smoking status, food consumption, salt consumption in the BP analysis and the laboratory in charge for cholesterol analysis. Within immigrant subjects, the results were stratified by variables of the migration pattern: age at immigration and length of residence in Italy. Results: Thirty seven thousand three hundred and eighty subjects were included in the analysis, 8.6% were born in an HMPC. Heterogeneous results were seen by the macro-areas of origin and sex, with male immigrants from CE Europe (ß = 8.77 mg/dl) and Asia (ß = 6.56 mg/dl) showing higher levels of TC than native-born, while female immigrants from Northern Africa showed lower levels of TC (ß = -8.64 mg/dl). BP levels were generally lower among immigrants. Immigrants residing in Italy for more than 20 years had lower levels of TC (ß = -2.9 mg/dl) than native-born. In contrast, immigrants who arrived <20 years ago or arrived older than 18 years had higher levels of TC. This trend was confirmed for CE Europeans and was inverted for Northern Africans. Conclusions: The large heterogeneity in the results depending on sex and macro-area of origin indicates the need for targeted intervention in each specific immigrant group. The results confirm that acculturation leads to a convergence toward the epidemiological profile of the host population that depends on the starting condition of the immigrant group.

To which extent are per-and poly-fluorinated substances associated to metabolic syndrome?

Exposure to per- and polyfluoroalkyl substances (PFAS), ubiquitous persistent environmental contaminants, has led to substantial global concern due to their potential environmental and human health effects. Several epidemiological studies have assessed the possible association between PFAS exposure and risk of metabolic syndrome (MetS), however, the results are ambiguous. The aim of this study was to assess the current human epidemiologic evidence on the association between exposure to PFAS and MetS. We performed a systematic search strategy using three electronic databases (PubMed, Scopus, and Web of Science) for relevant studies concerning the associations of PFAS with MetS and its clinical relevance from inception until January 2021. We undertook meta-analyses where there were five or more studies with exposure and outcomes assessments that were reasonably comparable. The pooled odd ratios (ORs) were calculated using random effects models and heterogeneity among studies was assessed by I2 index and Q test. A total of 12 cross-sectional studies (10 studies on the general population and two studies in the occupational settings) investigated the association between PFAS exposure and MetS. We pooled data from seven studies on the general population for perfluorooctanoic acid (PFOA) and perfluorooctanesulfonate (PFOS) and five studies for perfluorohexanesulfonate (PFHxS) and perfluorononanoic acid (PFNA). Predominately, most studies reported no statistically significant association between concentrations of PFAS and MetS. In the meta-analysis, the overall measure of effect was not statistically significant, showing no evidence of an association between concentrations of PFOA, PFOS, PFNA, and PFHxS and the risk of MetS. Based on the results of the meta-analysis, current small body of evidence does not support association between PFAS and MetS. However, due to limited number of studies and substantial heterogeneity, results should be interpreted with caution. Further scrutinizing cohort studies are needed to evaluate the association between various and less well-known PFAS substances and their mixture with MetS and its components in both adults and children in different settings.

The effectiveness of maternity waiting homes in reducing perinatal mortality: a case-control study in Ethiopia.

BACKGROUND: The 2030 Agenda for Sustainable Development aims to reduce neonatal mortality to at least 12 per 1000 live births. Most of the causes can be prevented or cured. Access to quality healthcare during pregnancy and labour is the key to reduce perinatal deaths, and maternity waiting homes (MWHs) may have an impact, especially for women who live far from the healthcare system. We conducted a case-control study to evaluate the effectiveness of MWH in reducing perinatal mortality in a secondary hospital in Ethiopia. METHODS: We did a nested case-control study from January 2014 through December 2017. The enrolled cases were mothers whose childbirth resulted in stillbirth or early neonatal death. The controls were mothers with an alive baby at 7 days or with an alive baby on discharge. We collected demographic, anamnestic, pregnancy-related and obstetric-related data. The effectiveness of the MWH on perinatal death was assessed by a logistic regression model, adjusted for all other variables investigated as potential confounders. We also did a sensitivity analysis to explore the role of twin pregnancies. RESULTS: We included 1175 cases and 2350 controls. The crude analysis showed a protective effect of the MWH towards perinatal mortality (OR=0.700; 95% CI: 0.505 to 0.972), even more protective after adjustment for confounders (adjusted OR (AOR)=0.452; 95% CI: 0.293 to 0.698). Sensitivity analyses showed a consistent result, even excluding twin pregnancies (AOR=0.550; 95% CI: 0.330 to 0.917). CONCLUSION: MWHs appear to reduce perinatal mortality by 55%. Our findings support the decision to invest in MWH to support pregnant women with higher quality and more comprehensive healthcare strategy, including quality antenatal care in peripheral primary care clinics, where risk factors can be recognised and women can be addressed for admission to MWH.

PFAS Concentrations and Cardiometabolic Traits in Highly Exposed Children and Adolescents.

BACKGROUND: Residents of a large area of north-eastern Italy were exposed for decades to high concentrations of perfluoroalkyl and polyfluoroalkyl substances (PFAS) via drinking water. Despite the large amount of evidence in adults of a positive association between serum PFAS and metabolic outcomes, studies focusing on children and adolescents are limited. We evaluated the associations between serum PFAS concentrations that were quantifiable in at least 40% of samples and lipid profile, blood pressure (BP) and body mass index (BMI) in highly exposed adolescents and children. METHODS: A cross-sectional analysis was conducted in 6669 adolescents (14-19 years) and 2693 children (8-11 years) enrolled in the health surveillance program of the Veneto Region. Non-fasting blood samples were obtained and analyzed for perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), perfluorohexanesulfonic acid (PFHxS), perfluorononanoic acid (PFNA), total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C) and triglycerides. Low-density lipoprotein cholesterol (LDL-C) was calculated. Systolic and diastolic BP were measured, and BMI z-score accounting for age and sex was estimated. The associations between ln-transformed PFAS (and categorized into quartiles) and continuous outcomes were assessed using generalized additive models. The weighted quantile sum regression approach was used to assess PFAS-mixture effects for each outcome. Analyses were stratified by gender and adjusted for potential confounders. RESULTS: Among adolescents, significant associations were detected between all investigated PFAS and TC, LDL-C, and to a lesser extent HDL-C. Among children, PFOS and PFNA had significant associations with TC, LDL-C and HDL-C, while PFOA and PFHxS had significant associations with HDL-C only. Higher serum concentrations of PFAS, particularly PFOS, were associated with lower BMI z-score. No statistically significant associations were observed between PFAS concentrations and BP. These results were confirmed by the multi-pollutant analysis. CONCLUSIONS: Our study supports a consistent association between PFAS concentration and serum lipids, stronger for PFOS and PFNA and with a greater magnitude among children compared to adolescents, and a negative association of PFAS with BMI.

Associations of Perfluoroalkyl Substances with Prevalence of Metabolic Syndrome in Highly Exposed Young Adult Community Residents-A Cross-Sectional Study in Veneto Region, Italy.

BACKGROUND: Studies on the association between perfluoroalkyl substances (PFAS) and metabolic syndrome (MetS) are limited, and results are inconsistent. We aimed to examine the associations between PFAS serum levels and the prevalence of MetS among highly exposed young adults (ages 20-39) residents of a large area of the Veneto Region (North-Eastern Italy) primarily stemming from PFAS water contamination before September 2013. A total of 15,876 eligible young adult residents living in the investigated municipalities were enrolled in the study from January 2017 to July 2019. METHODS: MetS was defined by using a modified harmonized definition requiring the presence of 3 of the following: obesity (body mass index ≥30), elevated triglyceride (TG), reduced high-density lipoprotein cholesterol, elevated blood pressure, and hemoglobin A1c ≥ 6.1% or self-reported diabetes mellitus or drug treatment for hyperglycemia. Multivariable generalized additive models were performed to identify the associations between four serum PFAS, including perfluorooctane sulfonic acid (PFOS), perfluorooctanoic acid (PFOA), perfluorohexane sulfonic acid (PFHxS), and perfluorononanoic acid (PFNA), and risk of MetS controlling for potential confounders. RESULTS: A total of 1282 participants (8.1%) met the criteria of MetS with a higher prevalence among men. PFOA, PFHxS, and PFNA were not associated with the risk of MetS, whereas PFOS showed a consistent protective effect against the risk of MetS (OR 0.76, (95% CI: 0.69, 0.85) per ln-PFOS). However, we found statistically significant positive associations between PFAS serum levels and individual components of MetS, mainly elevated blood pressure and elevated TG. CONCLUSION: Our results did not support a consistent association between PFAS and MetS and conflicting findings were observed for individual components of MetS.

Avoidable Hospitalization for Heart Failure Among a Cohort of 18- to 64-Year-Old Italian Citizens and Immigrants: Results From the Italian Network for Longitudinal Metropolitan Studies.

BACKGROUND: Heart failure (HF) represents a severe public health burden. In Europe, differences in hospitalizations for HF have been found between immigrants and native individuals, with inconsistent results. Immigrants face many barriers in their access to health services, and their needs may be poorly met. We aimed to compare the rates of avoidable hospitalization for HF among immigrants and native individuals in Italy. METHODS: All 18- to 64-year-old residents of Turin, Venice, Reggio Emilia, Modena, Bologna, and Rome between January 1, 2001 and December 31, 2013 were included in this multicenter open-cohort study. Immigrants from high migratory pressure countries (divided by area of origin) were compared with Italian citizens. Age-, sex-, and calendar year-adjusted hospitalization rate ratios and the 95% CIs of avoidable hospitalization for HF by citizenship were estimated using negative binomial regression models. The hospitalization rate ratios were summarized using a random effects meta-analysis. Additionally, we tested the contribution of socioeconomic status to these disparities. RESULTS: Of the 4 470 702 subjects included, 15.8% were immigrants from high migratory pressure countries. Overall, immigrants showed a nonsignificant increased risk of avoidable hospitalization for HF (hospitalization rate ratio, 1.26 [95% CI, 0.97-1.68]). Risks were higher for immigrants from Sub-Saharan Africa and for males from Northern Africa and Central-Eastern Europe than for their Italian citizen counterparts. Risks were attenuated adjusting for socioeconomic status, although they remained consistent with nonadjusted results. CONCLUSIONS: Adult immigrants from different geographic macroareas had higher risks of avoidable hospitalization for HF than Italian citizens. Possible explanations might be higher risk factors among immigrants and reduced access to primary health care services.

Evaluation of the medication reconciliation process and classification of discrepancies at hospital admission and discharge in Italy.

Background Medication errors at different transitions of care are common and potentially harmful. Medication reconciliation process should be evaluated to reduce the unintentional discrepancies. Objective This study aims to identify and classify unintentional medication discrepancies at hospital admission and discharge and associated risk factors. Setting Two general internal medicine and a pulmonology wards of an Italian non-academic hospital. Method A retrospective observational study was conducted among adult patients admitted to the wards. In order to evaluate the current medication reconciliation process of these wards, the frequency and type of unintentional chronic medication discrepancies between the physician assessment of home medication and hospital admission and discharge prescriptions were studied. Patients' characteristic associated with the presence of at least one unintentional discrepancy were evaluated. Main outcome measure Frequencies of unintentional medication discrepancies upon admission and discharge and associated patients' characteristics. Results Among the 144 patients enrolled in the study, 53 and 64 unintentional medication discrepancies were identified at hospital admission and at discharge, respectively. Both at admission and discharge a quarter of patients had at least one unintentional discrepancy. 'Medication omission' was the most frequent type of discrepancy identified and respiratory system and nervous system were the classes of medication with the highest rate of unintentional discrepancies. Unintentional discrepancies were more likely to occur in patients receiving more medicine pre-admission, longer hospitalization stays and coming from or discharged to a nursing home. Conclusion Transitions of care are critical moments for patient safety in terms of unintentional medication discrepancies and a more structured medication reconciliation process is needed. The medication reconciliation process should be considered in terms of a multidisciplinary approach involving all health professionals as well as patients and caregivers directly.

The Role of Maternal Citizenship on Pediatric Avoidable Hospitalization: A Birth Cohort Study in North-East Italy.

OBJECTIVE: Avoidable hospitalization (AH) has been widely studied as a possible measure of primary health care performance. Since studies evaluating AH in migrant children, particularly in Europe, are lacking, the aim of this study was to investigate the role of maternal citizenship on the risk of AH in children. METHODS: The cohort study included all live newborns recorded in the Medical Birth Register (MBR) of Friuli-Venezia Giulia Region (Italy) in the years 1989-2012, followed from 30 d after their birth up to the 14th year of life. Cox regression models were used to estimate Hazard Ratios (HRs) for any AH and for specific conditions. RESULTS: Among the 213,635 children included in the cohort, authors identified 23,011 AHs in 16,744 children, most of which occurred between 1 and 4 y of age. Children born to mothers from High Migration Pressure Countries had a higher risk of AH for any condition (HR 1.35; 95% CI = 1.27-1.44) than children born to Italian mothers. The risks were higher concerning gastroenteritis (HR 1.74; 1.57-1.94), upper respiratory tract infections (HR 1.58; 1.35-1.84), asthma (HR 1.53; 1.12-2.06) and bacterial pneumonia (HR 1.18; 1.01-1.37). There were no differences in urinary tract infections, short term complications of diabetes and perforated appendix. CONCLUSIONS: Despite the inclusiveness and universality of the Italian healthcare system, children born to immigrant mothers experienced more need of avoidable hospital care than children born to Italian mothers. Access barriers to primary care are plausible causes for the observed disparities.

National immunization strategies targeting migrants in six European countries.

Over the last three years an unprecedented flow of migrants arrived in Europe. There is evidence that vaccine preventable diseases have caused outbreaks in migrant holding centres. These outbreaks can be favored by a combination of factors including low immunization coverage, bad conditions that migrants face during their exhausting journey and overcrowding within holding facilities. In 2017, we conducted an online survey in Croatia, Greece, Italy, Malta, Portugal and Slovenia to explore the national immunization strategies targeting irregular migrants, refugees and asylum seekers. All countries stated that a national regulation supporting vaccination offer to migrants is available. Croatia, Italy, Portugal and Slovenia offer to migrant children and adolescents all vaccinations included in the National Immunization Plan; Greece and Malta offer only certain vaccinations, including those against diphtheria-tetanus-pertussis, poliomyelitis and measles-mumps-rubella. Croatia, Italy, Malta and Portugal also extend the vaccination offer to adults. All countries deliver vaccinations in holding centres and/or community health services, no one delivers vaccinations at entry site. Operating procedures that guarantee the migrants' access to vaccination at the community level are available only in Portugal. Data on administered vaccines is available at the national level in four countries: individual data in Malta and Croatia, aggregated data in Greece and Portugal. Data on vaccination uptake among migrants is available at national level only in Malta. Concluding, although diversified, strategies for migrant vaccination are in place in all the surveyed countries and generally in line with WHO and ECDC indications. Development of procedures to keep track of migrants' immunization data across countries, development of strategies to facilitate and monitor migrants' access to vaccinations at the community level and collection of data on vaccination uptake among migrants should be promoted to meet existing gaps.
