Temporal changes of vascular plant diversity in response to tree dieback in a mediterranean lowland forest

Palo Laziale wood is a small biotope of about 129 ha situated along the north coast of Rome. It is one of the last remaining patches of an ancient lowland floodplain forest that once covered the coastal area of the Lazio region. It contains several habitats and species of high conservation interest which has been included in the Natura2000 network. The forest suffered an impressive dieback event in 2003, coinciding with a particularly hot and dry summer. In the framework of an ecological restoration project (LIFE PRIMED LIFE17 NAT/GR/000511), a preliminary assessment of the biotic and abiotic components of the ecosystem was carried out, including a floristic analysis. This analysis was compared with that conducted in 1990 to assess whether there was any change in the species composition also following the forest dieback. Comparisons between biological forms, chorotypes and the Ellenberg indicators were also made in the analysis. The total flora of the site increased from 462 to 490 species. Moreover, there has been a turnover of species with the disappearance of some grassland and halophytic species and the appearance of allochthonous/ruderal and freshwater habitat species. Despite this, the flora remained unchanged in ecological terms, demonstrating a certain resilience of the plant species, confirming this approach to identify declining processes and support ecosystem-based restoration actions elsewhere

Pepper mild mottle virus in different water matrices

Abstract Background Pepper mild mottle virus (PMMoV), a plant virus belonging to Virgoviridae, has recently been suggested as a potential viral indicator for faecal pollution in aquatic environments, since it has been found to be abundantly excreted from healthy human subjects. Methods The occurrence, amount and diversity of PMMoV was investigated in water environments by nested RT-PCR and TaqMan based quantitative PCR. During 2017-2019, 251 water samples (92 urban wastewaters, 32 treated effluents, 16 surface water samples, 9 estuarine samples, 20 seawater samples, 67 groundwater samples, and 15 drinking waters) were analysed. Results PMMoV was detected in 73/92 (79%) wastewater samples, 22/32 (69%) treated sewages, 11/16 (69%) river samples, 6/9 (67%) estuarine samples, 5/20 (25%) bathing waters, and 9/67 (13%) groundwaters, whilst drinking water samples tested always negative. Mean viral concentrations (genome copies/L) were: raw sewage 4.2 × 106, treated sewage 7.4 × 105, river 3.2 × 103, estuarine waters 9.6 × 102, seawaters 3.0 × 102, groundwaters 7.7 × 101. Conclusions This study highlights the significant occurrence of PMMoV in aquatic environment in Italy, and a clear gradient of viral prevalence and concentrations from polluted to clean waters (wastewaters to drinking waters). Key messages PMMoV is ubiquitous throughout the water cycle in Italy with different concentrations. Studies are needed to evaluate the suitability of PMMoV as a viral indicator for human fecal pollution in waters

Differences in attitudes towards mental illness and psychiatry among medical students, before and after the academic course of psychiatry

BackgroundStigma towards mental illness and psychiatry have a major impact on psychiatric patients’ quality of life; in particular, prejudicial beliefs make it more difficult for future doctors to send patients to mental health services, leading to a delay of necessary care.AimsOur aim is to evaluate the stigma towards mental illness and psychiatry, in a sample of Italian medical students. We studied the differences between the first-year students who have not attended the academic course in psychiatry, compared to the senior students who have attended the psychiatric lectures.MethodsWe tested 113 medical students, using the following questionnaires:– Attitudes Towards Psychiatry (ATP 30);– Community Attitudes Towards Mental Ill (CAMI);– Perceived Discrimination Devaluation Scale (PDD), to assess the discrimination towards mental illness perceived in society;– Baron-Cohen's Empathy Quotient (EQ), to measure empathy.ResultsAmong the 113 students, 46 have already attended the academic course of psychiatry and CAMI scores were less stigmatizing as total score (P = 0.014) and in authoritarianism subscale (P = 0.049), social restriction (P = 0.022) and ideology of mental health in the community (P = 0.017). However, there were no statistically significant differences in empathy, perceived discrimination in the society and stigmatization of psychiatry.ConclusionsThe 67 students who have not attended the academic course of psychiatry are more stigmatizing, considering psychiatric patients as inferior people that require coercive attitudes, socially dangerous and that should be treated faraway from the community. Studying psychiatry is therefore useful to reduce, in the future doctors, these prejudices toward mentally ill patients.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec

Different attitudes toward psychiatry and psychiatric patients in nursing students: Can personal experiences reduce stigma?

BackgroundPsychiatric patients often do not receive the same health treatment reserved for patients with no mental disorders. Stigma in mental-health nurses can worsen the patients’ healing time and quality of care.ObjectiveTo explore the different attitudes towards mental illness and psychiatry in nursing students (NS) of the first and the final year of university, and the importance of having visited a psychiatric ward and having known a psychiatric patient.MethodsFifty NS completed the following tests:– Community attitudes towards mental ill (CAMI);– Attitudes towards psychiatry (ATP-30);– Empathy quotient (EQ).ResultsNS of the final year differ significantly from those of the first year in 4 CAMI items, in Authoritarianism subscale (P = 0.041), Social Restrictiveness (P = 0.029) and Community Mental Health Ideology (P = 0.045), indicating a more mature and responsible approach to psychiatric patients, without considering them a threat to be secluded. EQ does not show a significant difference in empathy, not even considering the individual items. Final year NS also have more positive attitudes toward Psychiatry in 3 ATP-30 items and total score (P = 0.01). Those who visited a psychiatric ward have more positive attitudes towards mental illness and Psychiatry, in 6 CAMI items and 3 ATP-30 items. Having personally known a psychiatric patient leads to positive attitudes in only a few CAMI items.ConclusionsLast-year NS, who have had more direct relationships with patients through practical training, have more empathetic and less stigmatizing attitudes. It is also very useful to attend a psychiatric ward during the nursing training.Normal 0 14 false false false IT X-NONE X-NONE.Disclosure of interestThe authors have not supplied their declaration of competing interest.</jats:sec

Potential use of untreated wastewater for assessing COVID-19 trends in southern Italy

As a complement to clinical disease surveillance, the monitoring of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) in wastewater can be used as an early warning system for impending epidemics. This study investigated the dynamics of SARS-CoV-2 in untreated wastew-ater with respect to the trend of coronavirus disease 2019 (COVID-19) prevalence in Southern Italy. A total of 210 wastewater samples were collected between May and November 2020 from 15 Apulian wastewater treatment plants (WWTP). The samples were concentrated in accordance with the stan-dard of World Health Organization (WHO, Geneva, Switzerland) procedure for Poliovirus sewage surveillance, and molecular analysis was undertaken with real-time reverse-transcription quantitative PCR (RT-(q) PCR). Viral ribonucleic acid (RNA) was found in 12.4% (26/210) of the samples. The virus concentration in the positive samples ranged from 8.8 × 102 to 6.5 × 104 genome copies/L. The receiver operating characteristic (ROC) curve modeling showed that at least 11 cases/100,000 inhabitants would occur after a wastewater sample was found to be positive for SARS-CoV-2 (sensi-tivity = 80%, specificity = 80.9%). To our knowledge, this is the first study in Italy that has applied wastewater-based epidemiology to predict COVID-19 prevalence. Further studies regarding methods that include all variables (meteorological phenomena, characteristics of the WWTP, etc.) affecting this type of wastewater surveillance data would be useful to improve data interpretation

Wastewater surveillance of SARS-CoV-2 variants in October-November 2022 in Italy: detection of XBB.1, BA.2.75 and rapid spread of the BQ.1 lineage

This study adds insight regarding the occurrence and spread of SARS-CoV-2 Variants of Concern (VOCs) and Var-iants of Interest (VOIs) in Italy in October and November 2022, by testing urban wastewater collected through-out the country. A total of 332 wastewater samples were collected from 20 Italian Regions/Autonomous Provinces (APs) within the framework of national SARS-CoV-2 environmental surveillance. Of these, 164 were collected in the first week of October and 168 in the first week of November. A similar to 1600 bp fragment of the spike protein was sequenced by Sanger (for individual samples) and long-read nanopore sequencing (for pooled Region/AP samples).In October, mutations characteristic of Omicron BA.4/BA.5 were detected in the vast majority (91 %) of the samples amplified by Sanger sequencing. A fraction of these sequences (9 %) also displayed the R346T mutation. Despite the low prevalence documented in clinical cases at the time of sampling, amino acid substitutions characteristic of sublineages BQ.1 or BQ.1.1 were detected in 5 % of sequenced samples from four Regions/APs. A significantly higher variability of sequences and variants was documented in November 2022, when the rate of se-quences harbouring mutations of lineages BQ.1 and BQ1.1 increased to 43 %, and the number of Regions/APs positive for the new Omicron subvariant more than tripled (n = 13) compared to October. Moreover, an increase in the number of sequences with the mutation package BA.4/BA.5 + R346T (18 %), as well as the detection of variants never observed before in wastewater in Italy, such as BA.2.75 and XBB.1 (the latter in a Region where no clinical cases asso-ciated with this variant had ever been documented) was recorded.The results suggest that, as predicted by the ECDC, BQ.1/BQ.1.1 is rapidly becoming dominant in late 2022. Environ-mental surveillance proves to be a powerful tool for tracking the spread of SARS-CoV-2 variants/subvariants in the population

Dietary patterns, foods, and food groups : relation to late-life cognitive disorders

The limited efficacy of disease-modifying therapeutic strategies for mild cognitive impairment (MCI) and Alzheimer\u2019s dementia (AD) underscores the need for preventive measures to reduce the burden of late-life cognitive impairment. The aim of the present review article was to investigate the relationship among dietary patterns, foods, and food groups and late-life cognitive disorders considering the results of observational studies published in the last three years (2014-2016). In the last decade, the association between diet and cognitive function or dementia has been largely investigated. However, more recently, the National Institute on Aging-Alzheimer\u2019s Association guidelines for AD and cognitive decline due to AD pathology introduced some evidence suggesting a direct relation between diet and changes in the brain structure and activity. Several studies focused on the role of the dietary patterns on late-life cognition, with accumulating evidence that combinations of foods and nutrients into certain patterns may act synergistically to provide stronger health effects than those conferred by their individual dietary components. In particular, higher adherence to a Mediterranean-type diet was associated with decreased cognitive decline, although the Mediterranean diet (MeDi) combines several foods, micronutrients, and macronutrients already separately proposed as potential protective factors against dementia and MCI. Moreover, also other emerging healthy dietary patterns such as the Dietary Approach to Stop Hypertension (DASH) and the Mediterranean-DASH diet Intervention for Neurodegenerative Delay (MIND) diets were associated with slower rates of cognitive decline and significant reduction in AD rate. Furthermore, some foods or food groups traditionally considered harmful such as eggs and red meat have been partially rehabilitated, while there is still a negative correlation of cognitive functions with added sugars and trans fatty acids, nutrients also increasing the cardiovascular risk. This would suggest a genesis for the same damage for aging brain

Pressure and pain In Systemic sclerosis/Scleroderma - an evaluation of a simple intervention (PISCES): randomised controlled trial protocol

Background: foot problems associated with Systemic Sclerosis (SSc)/Scleroderma have been reported to be both common and disabling. There are only limited data describing specifically, the mechanical changes occurring in the foot in SSc. A pilot project conducted in preparation for this trial confirmed the previous reports of foot related impairment and reduced foot function in people with SSc and demonstrated a link to mechanical etiologies. To-date there have been no formal studies of interventions directed at the foot problems experienced by people with Systemic Sclerosis. The primary aim of this trial is to evaluate whether foot pain and foot-related health status in people with Systemic Sclerosis can be improved through the provision of a simple pressure-relieving insole. Methods: the proposed trial is a pragmatic, multicenter, randomised controlled clinical trial following a completed pilot study. In four participating centres, 140 consenting patients with SSc and plantar foot pain will be randomised to receive either a commercially available pressure relieving and thermally insulating insole, or a sham insole with no cushioning or thermal properties. The primary end point is a reduction in pain measured using the Foot Function Index Pain subscale, 12 weeks after the start of intervention. Participants will complete the primary outcome measure (Foot Function Index pain sub-scale) prior to randomisation and at 12 weeks post randomisation. Secondary outcomes include participant reported pain and disability as derived from the Manchester Foot Pain and Disability Questionnaire and plantar pressures with and without the insoles in situ. Discussion: this trial protocol proposes a rigorous and potentially significant evaluation of a simple and readily provided therapeutic approach which, if effective, could be of a great benefit for this group of patients
