Wolbachia in Aedes koreicus: Rare Detections and Possible Implications.

The emerging distribution of new alien mosquito species was recently described in Europe. In addition to the invasion of Aedes albopictus, several studies have focused on monitoring and controlling other invasive Aedes species, as Aedes koreicus and Aedes japonicus. Considering the increasing development of insecticide resistance in Aedes mosquitoes, new control strategies, including the use of bacterial host symbionts, are proposed. However, little is known about the bacterial communities associated with these species, thus the identification of possible candidates for Symbiotic Control is currently limited. The characterization of the natural microbiota of field-collected Ae. koreicus mosquitoes from North-East Italy through PCR screening, identified native infections of Wolbachia in this species that is also largely colonized by Asaia bacteria. Since Asaia and Wolbachia are proposed as novel tools for Symbiotic Control, our study supports their use for innovative control strategies against new invasive species. Although the presence of Asaia was previously characterized in Ae. koreicus, our study characterized this Wolbachia strain, also inferring its phylogenetic position. The co-presence of Wolbachia and Asaia may provide additional information about microbial competition in mosquito, and to select suitable phenotypes for the suppression of pathogen transmission and for the manipulation of host reproduction in Ae. koreicus.

Presence of Known and Emerging Honey Bee Pathogens in Apiaries of Veneto Region (Northeast of Italy) during Spring 2020 and 2021

A progressive honey bee population decline has been reported worldwide during the last decades, and it could be attributed to several causes, in particular to the presence of pathogens and parasites that can act individually or in synergy. The health status of nine apiaries located in different areas of the Veneto region (northeast of Italy) was assessed for two consecutive years (2020 and 2021) in spring, during the resumption of honey bee activity, for determining the presence of known (Nosema spp., Varroa mite and viruses) and less known or emerging pathogens (Lotmaria passim and Crithidia mellificae) in honey bees. After honey bees sampling from each of the nine apiaries, Nosema apis, Nosema ceranae, L. passim, C. mellificae, ABPV, CBPV, IAPV, KBV, BQCV, SBV, DWV-A, DWV-B and V. destructor were investigated either by microscopic observation or PCR protocols. The viruses BQCV, SBV, CBPV followed by N. ceranae and L. passim were the most prevalent pathogens, and many of the investigated hives, despite asymptomatic, had different degrees of co-infection. This study aimed to highlight, during the resumption of honey bee activity in spring, the prevalence and spreading in the regional territory of different honey bee pathogens, which could alone or synergistically alter the homeostasis of bees colonies. The information gathered would increase our knowledge about the presence of these microorganisms and parasites in the territory and could contribute to improve beekeepers practice.

Anatomy of Anthropically Controlled Natural Lagoons through Geophysical, Geological, and Remote Sensing Observations: The Valli Di Comacchio (NE Italy) Case Study

Newly collected morphobathymetric and seismic reflection data from the Valli di Comacchio coastal lagoons, south of the Po River delta (Northeast Italy), combined with historical, remote sensing, and geodetic data highlight a complex geological evolution during the Holocene, strongly affected by anthropic control. All data allowed us to define the present-day depositional environment of the lagoons and reconstruct their recent (late Pleistocene/Holocene) geo-history. We focused on the effects of the anthropic impacts in modifying the pristine environments created by the Holocene transgression along the Adriatic Sea coast, at the mouth of a major river. They include land reclamation works, artificial damming, channel excavations, fluvial diversions, and a recent (last decades) increase in subsidence rate due to gas and water withdrawals. Despite the development of economic activities, which promoted occupation and exploitation of this area in the last millennia, the post-Glacial evolution of the lagoons shows the important role of inherited morphological features, such as sand ridges and barriers. This complex and relatively well-documented evolution makes the Comacchio lagoons a unique example of deep connections between natural processes and long-term human controls, offering insights into the management policies of these important and delicate environments challenged by global changes.

Dry grasslands on fluvial terraces of the middle reaches of river Piave in the North East Italy

Abstract Dry grassland vegetation on fluvial terraces along middle reaches of river Piave and river Brenta in Northeastern high Po plain were investigated through a phytosociological approach. Comparisons with ecologically analogous communities described from neighbouring territories lead to the description of a new association belonging to Centaureion dichroanthae alliance: Astragalo onobrychidis-Koelerietum pyramidatae. Residual fragments of Chrysopogon gryllus-dominated grassland on slighly deeper soils are refered to Chamaecytiso hirsuti-Chrysopogonetum grylli.

A Figurative Roman Period Monument Recently Recorded into the Collection of the National Union Museum Alba Iulia. Considerations Regarding its Significance

The scope of this scientific endeavour is the analysis of the Roman funeral monument, recently recovered by the judicial bodies from a certain individual from Alba Iulia. Upon the presentation of the method of recovery of the monument, the authors refer to an unfortunate implications’ phenomenon for the cultural heritage, which is occurring in Alba Iulia, where under lies the largest urban concentration within the former Roman province, namely Dacia. We are referring to the urban centre Apulum where, each year, numerous vestiges come to light, because of archaeological exploitations. Unfortunately, in numerous courtyards of the inhabitants, there still are Roman monuments which should belong into a museum. It would not be unproductive for the competent institutions to identify, inventory and take the required steps to bring and enter them into the museum related circuit. The idea is to prevent the trend of owning Roman monuments from Alba Iulia, which was also observed amid highly educated families. The topic is a funeral limestone document, kept in a fragmented state, in the shape of a truncated pyramid, which has a relief sculpture in the image of the hero Hercules. From the iconographic standpoint is part of the Farnese type, depicting the hero upon the completion of one of his twelve deeds, the killing of the lion from Nemeea. Within his cult also arose the funeral element, depicted by numerous sculptural monuments. According to the mythology, upon taming Cerberus, the famous dog of Hades, the lord of the Inferno, the hero becomes a role model for every mortal. By such” deed” Hercules defeated Death, and the deed turned out to be an example which perpetuated into the conscience of the people. Thereafter, after this special action he was entered among the deities. The iconographic analysis found that the stonemason failed to accurately represent part of the anatomical features of the character (lack of gender, bent legs, poor representation of the hair and beard), the monument remaining unfinished (the sculptural relief is not finished on the left side). Moreover, there are interventions after the Roman era, probably from the Middle Ages or the modern age, when a channelling was engraved around the head that would mark a halo of the Christian Saints, and within the pubic area a clumsy incision which could render a vulva. The images of Hercules on the Roman funerary monuments are numerous throughout the entire Empire, as well as into the North Danube Province. But on this type of sepulchral monument – pyramidal crowning or in the shape of a truncated pyramid – this representation of the hero is unique within the Province of Dacia. In general, such crowning is found in Dacia Superior and Porolissensis, originating into the North-East of Italy, better said, Aquileea city, wherefrom it spread in Pannonia, Noricum, Dalmatia, Moesia Superior and Germania Superior.

Venetoclax in combination with hypomethylating agents in previously untreated patients with acute myeloid leukemia ineligible for intensive treatment: a real-life multicenter experience

The addition of venetoclax to hypomethylating agents (HMA-V) improved the outcome of patients with newly diagnosed acute myeloid leukemia (AML) ineligible for intensive treatment. The aim of our study was to confirm data reported in literature, in a real-life multicenter experience. We retrospectively evaluated 56 naïve AML patients who received HMA-V at 8 different collaborating Hematology Units in the North-East of Italy, from September 2018 to October 2020. Patients received azacitidine or decitabine at standard dose, adding venetoclax starting from cycle 1–3. The median time-to-response was 2 cycles and composite complete remission rate (CCR) was 67.9%. Thirteen out of 38 responders (34.2%) relapsed, with a median response duration of 13.7 months. Transfusion independence (TI) was obtained in 27 (87.0%) and 28 (90.3%) out of 31 patients for red blood cells and platelets, respectively. Median OS was 12.3 months (95% CI, 8.1–16.5), and median PFS was 11.3 months (95% CI, 4.6–17.9). Cytogenetic risk was the only variable impacting on survival, while no differences were observed stratifying patients by age, bone marrow blasts, WHO classification or type of HMA. In conclusion, our real-life multicenter experience indicates that HMA-V treatment allows achieving good response rates in naïve AML patients, ineligible for intensive chemotherapy.

Are Small Animal Practitioners Occupationally Exposed to Leptospirosis? Results of a Serological Survey.

Leptospirosis is a worldwide zoonosis frequently responsible for clinical disease in dogs and rarely reported in human people. The risk of human exposure to Leptospira has been investigated in a sample population working in the northeast of Italy, a geographical area with high endemicity of canine leptospirosis. Two-hundred twenty-one human serum samples were analyzed for Leptospira microagglutination test (MAT): 112 clinical freelance small animal practitioners (exposed subjects) and 109 people not occupationally exposed to Leptospira-infected animals (unexposed subjects) were voluntarily enrolled. Despite the previously reported serological detection of antibodies vs. Leptospira in people in different Italian regions, this study did not detect any reactivity in the investigated population. This study shows that veterinarians do not appear to be at a greater risk of leptospirosis than the reference population. This may be due to both veterinarian awareness of the Leptospira zoonotic risk and the efficiency of the preventive measures and management of patients. Moreover, it could be the result of the relatively low excretion of Leptospira in symptomatic dogs, which can be considered as an environmental sentinel for Leptospira presence rather than a vehicle of transmission.

The impact of the use of treatments not included in the reimbursement classes in the care of rare patients: a real world study.

Rare disease (RD) patients present complex therapeutic needs. When there are therapeutic options available, orphan drugs (OD) represent only a limited proportion of prescribed treatments. This study aims at investigating the real-world use of treatments considered not replaceable and essential for the care of RD patients, besides their reimbursement status, using data from a RD population-based registry. The study is based on data derived from the Veneto region RD registry. For the period 2019-2020, we have analyzed the prescriptions of treatments defined as essential and not replaceable, besides their reimbursement status, included in therapeutic plans issued by RD expert Centres for patients resident in the Veneto region (north-east of Italy, 4.9 million inh.). The correspondent pharmaceutical costs have been estimated as well. In the study period there have been 22.186 prescriptions, included in 9,197 therapeutic plans issued for RD patients resident in the monitored area. The plans present a high level of complexity in terms of number and type of prescribed treatments, with 11% of the plans containing 5 or more prescriptions. 3,041 medicinal products have been prescribed in the study period, of whom 41% are drugs. Although these prescriptions are distributed among all the groups of RD patients, only a limited proportion of products (n=10) is responsible of the 50% of all the costs attributable to these treatments. Overall, the annual cost attributable to essential treatments not directly reimbursed by the national health system is quantifiable in 1 million euros per million inhabitants. This real-world study offers a snapshot of the complexity of treatments defined as essential, besides their reimbursement status, in therapeutic plans issued by RD expert Centres for a consistent group of RD patients monitored by a population-based registry. It highlights the complexity of the therapeutic approaches put in place for the care of RD patients, including drugs and a variety of other treatments. Population-based registries collecting data on prescribed treatments can contribute to understand the therapeutic needs of RD patients, treatments' accessibility and the impact of prescriptions on the global pharmaceutical costs.

Short-term and long-term effects of antimicrobial use on antimicrobial resistance in broiler and turkey farms

ABSTRACT Antimicrobials have been widely used in poultry, promoting antimicrobial resistance (AMR) emergence and spread. Resistant bacteria selected by antimicrobial use (AMU) can contaminate the farm environment and transfer resistance genes to other bacteria, providing opportunities for persistence and (re-)colonization of subsequent flocks and potentially jeopardizing antimicrobial treatments. We investigated the effects of AMU on AMR in poultry in the long-term (due to historical AMU in the farm) and in the short-term (due to current AMU in a flock). Litter samples from 35 broiler and 35 turkey farms in North-East Italy were sampled longitudinally for AMR testing of E. coli indicator bacteria in 2019/2020. Differences in AMR as a function of historical AMU (Defined Daily Doses in 2016–2018), current AMU in the sampled flock, farm size and season were tested using Generalized Estimating Equation regression analysis. In both broilers and turkeys, the highest resistance levels were observed for sulfamethoxazole (>70%), followed by ampicillin (54–60%). Only a few positive associations between historical levels of penicillin use and the specific resistance levels to penicillin in broiler farms, and the overall historical AMU and resistance to trimethoprim in turkey flocks, were significant. Current AMU showed significant effects on resistance to sulfamethoxazole, trimethoprim, ciprofloxacin and tetracycline in turkey flocks. Significant effects of farm size on some AMR levels were also identified. We found a stronger association between current AMU and AMR compared to historical AMU and AMR. AMR persistence in the farm environment in the absence of direct AMU pressure needs to be further investigated. RESEARCH HIGHLIGHTS Sulfamethoxazole and ampicillin resistance are the highest in E. coli isolates of both broilers and turkeys. Short-term effects of antibiotic use on resistance are seen more often than long-term effects. Historical penicillin use is associated with penicillin resistance in broilers. There is an association between historical use and resistance to trimethoprim in turkeys.

Suicide mortality among psychiatric patients in Northeast Italy: a 10-year cohort study.

The present study investigated the relationship between suicide mortality and contact with a community mental health centre (CMHC) among the adult population in the Veneto Region (northeast Italy, population 4.9 million). Specifically, it estimated the effects of age, gender, time elapsed since the first contact with a CMHC, calendar year of diagnosis and diagnostic category on suicide mortality and modality. The regional mortality archive was linked to electronic medical records for all residents aged 18-84 years who had been admitted to a CMHC in the Veneto Region in 2008. In total, 54 350 subjects diagnosed with a mental disorder were included in the cohort and followed up for a period of 10 years, ending in 2018. Years of life lost (YLL) were computed and suicide mortality was estimated as a mortality rate ratio (MRR). During the follow-up period, 4.4% of all registered deaths were from suicide, but, given the premature age of death (mean 52.2 years), suicide death accounted for 8.7% of YLL; this percentage was particularly high among patients with borderline personality disorder (27.2%), substance use disorder (12.1%) and bipolar disorder (11.5%) who also presented the highest suicide mortality rates. Suicide mortality rates were halved in female patients (MRR 0.45; 95% CI 0.37-0.55), highest in patients aged 45-54 years (MRR 1.56; 95% CI 1.09-2.23), and particularly elevated in the 2 months following first contact with CMHCs (MRR 10.4; 95% CI 5.30-20.3). A sensitivity analysis restricted to patients first diagnosed in 2008 confirmed the results. The most common modalities of suicide were hanging (47%), jumping (18%), poisoning (13%) and drowning (10%), whereas suicide from firearm was rare (4%). Gender, age at death and time since first contact with CMHCs influenced suicide modality. Suicide prevention strategies must be promptly initiated after patients' first contact with CMHCs. Patients diagnosed with borderline personality disorder, substance use disorder and bipolar disorder may be at particularly high risk for suicide.

Early and midterm outcomes following open surgical conversion after failed endovascular aneurysm repair from the "Italian North-easT RegIstry of surgical Conversion AfTer Evar" (INTRICATE).

To report the early and mid-term outcomes following open surgical conversion (OSC) after failed endovascular aortic repair (EVAR) using data from a multicentric registry. A retrospective study was carried out on consecutive patients undergoing OSC after failed EVAR at eight tertiary vascular units from the same geographic area in the North-East of Italy, from April 2005 to November 2019. Study endpoints included early and follow-up outcomes. A total of 144 consecutive patients were included in the study. Endoleaks were the most common indication for OSC (50.7%), with endograft infection (24.6%) and occlusion (21.9%) being the second most prevalent causes. The overall rate of 30-day all-cause mortality was 13.9% (n= 20); 32 patients (22.2%) experienced at least one major complication. Mean length of stay was 13± 12.7days. On multivariate logistic regression, age (odds ratio [OR], 1.09; 95% confidence interval [CI], 1.01-1-19; P= .02), renal clamping time (OR, 1.07; 95% CI, 1.02-1.13; P= .01), and suprarenal/celiac clamping (OR, 6.66; 95% CI, 1.81-27.1; P= .005) were identified as independent predictors of perioperative major complications. Age was the only factor associated with perioperative mortality at 30days. Renal clamping time >25minutes had sensitivity of 65% and specificity of 70% in predicting the occurring of major adverse events (area under the curve, 0.72; 95% CI, 0.61-0.82). At 5years, estimated survival was significantly lower for patients treated due to aortic rupture/dissection (28%; 95% CI, 13%-61%), compared with patients in whom the indication for treatment was endoleak (54%; 95% CI, 40%-73%), infection (53%; 95% CI, 30%-94%), or thrombosis (82%; 95% CI, 62%-100%; P= .0019). Five-year survival rates were significantly lower in patients who received emergent treatment (28%; 95% CI, 14%-55%) as compared with those who were treated in an urgent (67%; 95% CI, 48%-93%) or elective setting (57%; 95% CI, 43%-76%; P= .00026). Subjects who received suprarenal/celiac (54%; 95% CI, 36%-82%) or suprarenal (46%; 95% CI, 34%-62%) aortic cross-clamping had lower survival rates at 5years than those whose aortic-cross clamp site was infrarenal (76%; 95% CI, 59%-97%; P= .041). Using multivariate Cox proportional hazard, older age and emergency setting were independently associated with higher risk for overall 5-year mortality. OSC after failed EVAR was associated with relatively high rates of early morbidity and mortality, particularly for emergency setting surgery. Endoleaks with secondary sac expansion were the main indication for OSC, and suprarenal aortic cross-clamping was frequently required. Endograft infection and emergent treatment remained associated with poorer short- and long-term survival.

Pilot study of home phototherapy for neonatal jaundice monitored in maternity ward during the enforced Italy-wide COVID-19 national lockdown.

In Italy, where neonatal jaundice treatment is required, it is largely carried out in hospitals. However, it is possible to safely administer home phototherapy (HPT). We report our pilot center’s experience of HPT and its potential benefits during the COVID-19-enforced national lockdown. This is an observational study performed at the Policlinic Abano Terme, a suburban hospital that covers a large catchment area near the Euganean Hills in Northeast Italy with around 1000 deliveries per year. HPT was started after regular nursery discharge, and the mothers brought the neonates back to the hospital maternity ward each day to check infants’ bilirubin levels, weight, and general state of health, until it was deemed safe to stop. The efficacy of HPT in bilirubin reduction, hospital readmission rates, and parental satisfaction were evaluated. Thirty infants received HPT. In 4 of these infants, HPT was associated with total serum bilirubin (TSB) between 75 and 95th percentile (high-intermediate-risk zone) and in 26 infants HPT was associated with TSB > 95th percentile (high-risk zone) of the Bhutani nomogram. Among these 30 infants, 27 (90%) completed the HPT with a progressive decrease of TSB levels with 4 neonates requiring a second course and 3 infants requiring a third course of 24-h HPT. Three (10%) neonates failed HPT and were readmitted after one 24-h phototherapy course. No abnormalities of breastfeeding, body weight (defined as > 10% decrease), temperature, nor COVID infections were detected following HPT consultation in the neonatal ward. Home treatment efficacy with varying degrees of parental satisfaction occurred in all but 3 cases that involved difficulties with the equipment and inconsistent lamp manipulation practices.Conclusion: Our pilot study suggests that HPT for neonatal jaundice can be carried out effectively and with parental satisfaction as supported by daily back bilirubin monitoring in the maternity ward during the enforced COVID-19 national lockdown in Italy. What is Known:• No high-quality evidence is currently available to support or refute the practice of phototherapy in patients’ own homes.What is New:• Phototherapy can be delivered at home in a select group of infants and could be an ideal option if parents are able to return with their infants to the hospital maternity ward for daily follow-up.• It can be as effective as inpatient phototherapy and potentially helps in delivering family-centered care.

Bacterial Complexity of Traditional Mountain Butter Is Affected by the Malga-Farm of Production

Bacteria can play different roles affecting flavors and food characteristics. Few studies have described the bacterial microbiota of butter. In the present paper, next-generation sequencing was used to determine bacterial diversity, together with aromatic characteristics, in raw cow milk butter processed by traditional fermentation, in fourteen small farms called “Malga”, located in the Trentino province (Alpine region, North-East of Italy). The physicochemical and aromatic characterization of traditional mountain butter (TMB) showed a low moisture level depending on the Malga producing the butter. Counts of lactic acid bacteria, Staphylococci, and coliforms, as well as diacetyl/acetoin concentrations exhibited changes according to the geographical origin of Malga and the residual humidity of butter. MiSeq Illumina data analysis revealed that the relative abundance of Lactococcus was higher in TMB samples with the highest values of acetoin (acetoin higher than 10 mg/kg). The traditional mountain butter bacterial community was characterized by a “core dominance” of psychrotrophic genera, mainly Acinetobacter and Pseudomonas, but according to ANCOM analysis, a complex bacterial population emerged and specific bacterial genera were able to characterize the TMB bacteria community, with their high abundance, based on the Malga producing the butter.

The Sustained Psychological Impact of the COVID-19 Pandemic on Health Care Workers One Year after the Outbreak-A Repeated Cross-Sectional Survey in a Tertiary Hospital of North-East Italy.

This study aimed to evaluate the mental health outcomes of health care workers (HCWs) of the Verona academic hospital trust (Italy) one year after the outbreak of COVID-19 and to identify predicted risk factors. A web-based survey was conducted from mid-April to mid-May 2021 on hospital workers one year after the first evaluation performed during the lock-down phase of the COVID-19 pandemic. Post-traumatic stress, general anxiety, depression, and burnout were assessed by using, respectively, the impact of event scale (IES-R), the self-rating anxiety scale (SAS), the patient health questionnaire (PHQ-9) and the Maslach burnout inventory-general survey (MBI-GS). Multivariate logistic regression analysis was performed to identify factors associated with each of the four mental health outcomes one year after the COVID-19 outbreak. A total of 1033 HCWs participated. The percentage of HCWs scoring above the cut-off increased from 2020 to 2021 in all of the outcome domains (anxiety, 50.1% vs. 55.7, p < 0.05; depression, 26.6% vs. 40.6%, p < 0.001; burnout, 28.6% vs. 40.6%, p < 0.001; chi-square test), with the exception of post-traumatic distress. There was also an increase when stratifying by occupation and workplace, with a greater increase for depression and burnout. Multivariate analysis revealed that, one year after the COVID-19 outbreak, nurses were at the greatest risk of anxiety and depression, whereas residents were at the greatest risk of burnout (in terms of low professional efficacy). Working in intensive care units was associated with an increased risk of developing severe emotional exhaustion and a cynical attitude towards work.

The Morphological Evolution of a Step–Pool Stream after an Exceptional Flood and Subsequent Ordinary Flow Conditions

Mountain streams are frequently characterized by step–pool morphology that provides stability and energy dissipation to the channel network. Large flooding events can overturn the equilibrium of the step–pool condition by altering the entire configuration. This work focuses on the impact of the “Vaia” storm (27–30 October 2018) on a step–pool mountain stream (Rio Cordon, Northeast Italy) and on its evolution after two years of ordinary flow conditions. To achieve the aims, this work uses both remote sensing data (LiDAR and UAV) and direct field measurements (i.e., longitudinal profiles and grain sizes distributions) performed pre-event, post-event, and 2 years later (current conditions). The results show a significant widening (width +81%, area +68%) and the creation of a new avulsion after the storm and a substantial change between the number of units (51 in the pre-event, 22 post-event, and 51 in the current conditions) and characteristics of step–pool sequences between pre- and post-conditions. Furthermore, it proves the ongoing processes of morphological stabilization since the current step–pool sequences parameters are heading back to the pre-event values. Such results suggest clear susceptibility of step–pool to exceptional events and fast recovery of such setting during barely two years of ordinary flow conditions.

Impact of vaccination on the spread of SARS-CoV-2 infection in north-east Italy nursing homes. A propensity score and risk analysis.

BackgroundIn the Veneto Region, 421,000 coronavirus 2019 disease (COVID-19) cases and 11,000 deaths have been reported since 21 February 2020. The pandemic spread particularly in nursing homes (NH).ObjectiveThis study estimated the impact of SARS-CoV-2 infection among NH residents, focusing on the risk of hospitalisation and death due to COVID-19 compared with the general older population. It also provided evidence of risk changes over time.MethodsOlder people, resident in Veneto, were enrolled from the regional registry of the population. We collected also information about demographic characteristics, chronic diseases, COVID-19 positivity, NH institutionalization, hospitalisation and date of death. Patients were assigned to NH or non-NH residents groups through a propensity score 1:1 matching. The follow-up period was defined as 21 February 2020 – 3 May 2021 and then divided into three waves. Risk ratios (RRs) and 95% confidence interval were estimated by using Poisson models with robust estimation of variance.ResultsNH residents showed a higher risk of COVID-19 infection (RR = 6.28; 6.03–6.54), hospitalisation for COVID-19 (RR = 2.20; 2.05–2.36) and death with COVID-19 (RR = 6.07; 5.58–6.61).ConclusionNH residents shared common spaces with other patients and healthcare professionals and were more exposed to infections. Nonetheless, in Italy from late December 2020 to May 2021, 95% of NH residents and their healthcare professionals received at least one vaccine dose and RRs for all outcomes decreased in NH.

Transnational Cross-Border Family Ties: Diasporic Lives of Bangladeshis in Italy and Beyond

The scope of this paper is to gain a better understanding of how Bangladeshi migrants in Italy maintain transnational family attachments, across multiple destinations, with the home country as well as with several host countries. The data comes from fieldwork in Northeast Italy. Research methods include in-depth interviews and participant observation. The findings reveal that a high proportion of Bangladeshi migrants maintain a variety of transnational and diasporic ties with their family and friends living in the country of origin and different European countries. These include family obligations, remittances, establishing businesses back home, visits and communication. They also preserve their national identity in this host society by maintaining cultural ways of belonging and through religious practices and involvement in Bangladeshi politics. The findings have also shown that Italian Bangladeshi families work to foster transnational family ties among the new generations born in Italy, who have little knowledge of their ancestral country. On a final note, this paper argues that transnational connections with the homeland play an important role in shaping the diasporic lives of Bangladeshis in Italy.

Assessing the impact of artificial summer drainage on the benthic macroinvertebrates in a freshwater wetland in northeast Italy

Valle Mandriole is one of the two last remaining freshwater wetlands in the coastal area of Ravenna (NE Italy). In 2011, a management technique that involves the complete drainage of the southern portion of Valle Mandriole during summer has been undertaken. In the present study, the effects of this artificial drying on the benthic macroinvertebrate fauna were assessed using a beyond before-after-control-impact (beyond BACI) sampling design. Macroinvertebrates dwelling on macrophytes and in bare sediments were sampled in the impact location and in four control locations, two times before and two times after the drying period. Simultaneously, water samples were collected to monitor chemical properties potentially affecting the studied organisms. Biological and chemical data were analysed by multivariate statistical methods. The statistical analysis did not detect any significant effect of the management action on the benthic macroinvertebrates or on the water chemical and physical properties. This contrasts with some previous results, suggesting that the effects of a management strategy based on draining completely dry and then reflooding a wetland area are site specific. However, it is necessary to consider that the present study does have some limitations, in particular, the differences between impact and control locations and the timing of the sampling. The highest biodiversity was observed in one small and isolated control location; this highlights how maintaining, protecting, restoring and even creating small ponds may play an important role in biodiversity conservation.
