Partial replacement of mineral fertilisers with animal manures in an apple orchard: Effects on GHG emission. JOURNAL OF ENVIRONMENTAL MANAGEMENT 2024; 356:120552. [PMID: 38531128 DOI: 10.1016/j.jenvman.2024.120552] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/07/2023] [Revised: 02/27/2024] [Accepted: 03/04/2024] [Indexed: 03/28/2024]
Abstract
Partial replacement of mineral fertilisers (MF) with animal manures is a good alternative to reduce MF use and increase both nutrient cycling in agriculture and soil organic matter. However, the adoption of this practice must not lead to increased environmental impacts. In this two-year study conducted in an apple orchard, MF were partially replaced with various animal manures, including cattle slurry (CS), acidified cattle slurry (ACS), solid cattle manure (CsM), or poultry manure (PM), and their impacts on greenhouse gas emission (GHG: CO2, N2O and CH4) were examined. A control (CTRL) receiving only MF served as the baseline, representing the conventional scenario in orchard fertilisation. Overall, replacing MF with manures increased GHG emissions, with the magnitude of the impacts depending on the specific characteristics of the manures and the amount of nutrients and organic matter applied. Comparing to the CTRL, application of ACS and CS led to higher CH4 and N2O emissions, while PM application increased both N2O and CO2 emissions. In contrast, replacement with PM and CsM decreased CH4 emissions. Nevertheless, results varied between the two years, influenced by several factors, including soil conditions. While acidification showed potential to mitigate CH4 emissions, it also led to increased N2O emissions compared to CS, particularly in 2022, suggesting the need for further investigation to avoid emission trade-offs. Replacement with CS (20.49 t CO2-eq ha-1) and CsM (20.30 t CO2-eq ha-1) showed comparable global warming potential (GWP) to the conventional scenario (CTRL, 19.49 t CO2-eq ha-1), highlighting their potential as viable MF substitutes.

Emergency department contribution to HCV elimination in the Iberian Peninsula. Int J Emerg Med 2024; 17:5. [PMID: 38178000 PMCID: PMC10768527 DOI: 10.1186/s12245-023-00570-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/04/2022] [Accepted: 12/01/2023] [Indexed: 01/06/2024] Open
Abstract
BACKGROUND Undiagnosed cases of hepatitis C virus (HCV) infection result in significant morbidity and mortality, further transmission, and increased public health costs. Testing in emergency departments (EDs) is an opportunity to expand HCV screening. The goal of this project was to increase the proportion of eligible patients screened for HCV in urban areas. METHODS An opportunistic automated HCV screening program was implemented in the EDs of 4 public hospitals in Spain and Portugal at different periods between 2018 and 2023. HCV prevalence was prospectively evaluated, and single-step or reflex testing was used for confirmation in the same sample. RESULTS More than 90% of the population eligible for testing were screened in the participating centers. We found HCV antibody seroprevalence rates ranging from 0.6 to 3.9%, with between 19 and 53% of viremic individuals. CONCLUSIONS Opportunistic HCV screening in EDs is feasible, does not disrupt ED activities, is highly effective in increasing diagnosis, and contributes to WHO's HCV elimination goals.

PRO-Act: a healthcare provider workshop outlining the added value of implementing PROs in routine HIV practice. J Patient Rep Outcomes 2023; 7:50. [PMID: 37261556 DOI: 10.1186/s41687-023-00584-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Accepted: 04/24/2023] [Indexed: 06/02/2023] Open
Abstract
Patient Reported Outcomes (PROs) are an evidenced way of adding value to routine clinical care. As a source of unique information on the effect of a medical condition and its treatment from the patients' perspective (Mercieca-Bebber et al. in Patient Relat Outcome Meas 9: 353-367, https://doi.org/10.2147/PROM.S156279 , 2018), PROs allow for an improved assessment in routine clinical care of symptoms, side effects, functional outcomes (physical, sexual, social, emotional, cognitive functioning), and health-related quality of life (HRQoL). By helping to align healthcare providers' interventions with what matters most to the patient, PROs contribute to the individualized choice of Anti-Retroviral Therapy (Carfora et al. in PLoS ONE 17(4): e0267030, https://doi.org/10.1371/journal.pone.0267030 , 2022) as a paramount component of tailored and person-centred care management, in routine clinical practice. This article outlines a practical framework and process tested in Portugal to raise awareness of PROs' added value, and to help guide first steps in the implementation and seamless integration of PROs, in routine HIV care.

Cardiac arrest following sugammadex administration. Anaesth Rep 2023; 11:e12233.

Abstract
A 68-year-old man underwent elective surgical repair of an abdominal wall hernia under general anaesthesia. The operation required muscle relaxation, for which we used rocuronium. Following completion of surgery, 180 mg sugammadex was administered intravenously. Shortly afterwards, the patient became severely bradycardic with hypotension, refractory to treatment with ephedrine. This progressed to a pulseless electrical activity cardiac arrest. After 4 min of cardiopulmonary resuscitation, there was return of spontaneous circulation and, following a period of haemodynamic stability in which general anaesthesia was maintained, the patient emerged from anaesthesia without incident. He remained haemodynamically stable until discharge. Post-resuscitation investigations including the serum tryptase level were unremarkable except for a mild respiratory acidosis and slightly elevated D-dimers. Sugammadex-induced bradycardia has previously been described, but its mechanism remains unknown. We believe that sugammadex was the cause of cardiac arrest in this case because of the timing and sequence of events, the evolution to pulseless electric activity and the relatively uneventful post-arrest clinical course. We hope that our report will help to promote awareness about this potential complication of a now commonly-used drug.

Abstract
INTRODUCTION Late HIV diagnosis is associated with increased morbidity, mortality and risk of onward transmission. Increasing HIV early diagnosis is still a priority. In this observational study with historical control, we determined the impact of an opportunistic HIV screening strategy in the reduction of late diagnosis and missed opportunities for earlier diagnosis. METHODS The screening programme was implemented in the emergency department (ED) of the Hospital de Cascais between September 2018 and September 2021. Eligible patients were aged 18-64 years, with no known HIV diagnosis or antibody testing performed in the previous year, and who required blood work for any reason. Out of the 252 153 emergency visits to the ED, we identified 43 153 (17.1%) patients eligible for HIV testing. Among the total population eligible for the screening, 38 357 (88.9%) patients were ultimately tested for HIV. Impact of the ED screening was determined by analysing late diagnosis in the ED and missed opportunities at different healthcare settings 3 years before and 3 years after the start of the ED screening. RESULTS After 3 years of automated HIV ED testing, we found 69 newly diagnosed HIV cases (54% male, 39% Portuguese nationals, mean age 40.5 years). When comparing the characteristics of HIV diagnoses made in the ED, we observed a significant reduction in the number of people with late HIV diagnosis before and after implementation of the screening programme (78.4% vs. 39.1%, respectively; p = 0.0291). The mean number of missed opportunities for diagnosis also fell (2.6 vs. 1.5 annual encounters with the healthcare system per patient, p = 0.0997). CONCLUSIONS People living with HIV in Cascais and their providers miss several opportunities for earlier diagnosis. Opportunistic screening strategies in settings previously deemed to be unconventional, such as EDs, are feasible and effective in mitigating missed opportunities for timely HIV diagnosis.

Abstract
OBJECTIVES HIV outcomes centre primarily around clinical markers with limited focus on patient-reported outcomes. With a global trend towards capturing the outcomes that matter most to patients, there is agreement that standardizing the definition of value in HIV care is key to their incorporation. This study aims to address the lack of routine, standardized data in HIV care. METHODS An international working group (WG) of 37 experts and patients, and a steering group (SG) of 18 experts were convened from 14 countries. The project team (PT) identified outcomes by conducting a literature review, screening 1979 articles and reviewing the full texts of 547 of these articles. Semi-structured interviews and advisory groups were performed with the WG, SG and people living with HIV to add to the list of potentially relevant outcomes. The WG voted via a modified Delphi process - informed by six Zoom calls - to establish a core set of outcomes for use in clinical practice. RESULTS From 156 identified outcomes, consensus was reached to include three patient-reported outcomes, four clinician-reported measures and one administratively reported outcome; standardized measures were included. The WG also reached agreement to measure 22 risk-adjustment variables. This outcome set can be applied to any person living with HIV aged > 18 years. CONCLUSIONS Adoption of the HIV360 outcome set will enable healthcare providers to record, compare and integrate standardized metrics across treatment sites to drive quality improvement in HIV care.

Abstract
ABSTRACT The present study aimed to evaluate the occurrence of polymorphisms in Diacylglycerol acyltransferase (DGTA-1 and 2), Fatty acid synthase (FASN), Stearoyl-CoA desaturase (SCD) genes and the Thioesterase domain of FASN (TE-FASN) gene that may be related to the lipid profile. In the experiment, a total of 84 sheep from different genetic groups were used. For the evaluation of the polymorphism of the genes, PCR-Single Strand Conformation Polymorphism (SSCP) technique and subsequent sequencing were used. In DGAT-2 gene, four genotypes were identified with the presence of 6 polymorphisms, with two (c.229T> C; c.255T> C) that resulted into the exchange of phenylalanine by leucine. In FASN gene, two genotypes were identified. In TE-FASN gene, three genotypes and 17 polymorphisms were identified. DGAT-1 and SCD genes did not reveal the occurrence of polymorphism. There was difference in relation to C14: 0, C18: 0 fatty acids and Δ9-desaturase C18 for DGAT-2 gene and of C18: 2ω6t for TE-FASN. There were differences among the genetic groups for C10: 0, C12: 0, C17: 0, C18: 2ω6t, C18: 3ω3, C20: 2, total of ω3, ω3/ω6 and atherogenicity index. There is occurrence of polymorphism of DGAT-2 and TE-FASN genes and these should be further studied in sheep since they revealed influence of the genotypes on the fatty acid profile.

Abstract
ABSTRACT The purpose was to evaluate the effects of gender and of different genotypes of chickens on the physicochemical parameters and centesimal composition, related to the quality of meat. The design was completely randomized arranged in 5x2 factorial scheme, five genotypes (Índio Gigante - IG; New Hampshire - NHS; Gigante Negra de Jersey - GNJ; poultry from the crossing between the IG and NHS breeds - IG x NHS; and between the IG and GNJ breeds - IG x GNJ) and two genders, with five repetitions and each one represented by three poultry, totaling 150 animals, slaughtered at 105 days. The parameters evaluated on the breast and thigh were: centesimal composition (moisture, ether extract - EE, protein and ash), ultimate pH, color (L*- luminosity, a*- redness, b* -yellowness, C* - chroma index and h* - hue angle), weight loss by cooking (WLC) and shear force (SF). The IG genotype had the highest average of ultimate pH of the breast (6.03). The NHS and IG x NHS genotypes showed, respectively, higher average of L * (58.93) and a* (1.92) of the breast. The IG, IG x NHS and IG x GNJ showed the highest values of b* of the breast (12.53, 13.37 and 12.69, respectively). The IG poultry showed high average of SF of the breast and thigh (4.79 and 5.01kgf, respectively). The IG x NHS and IG x GNJ genotypes showed the lowest ultimate pH values of the thigh (6.13 and 6.02, respectively). The IG x GNJ genotype showed a high average of b* of the thigh (14.94) and the NHS had a high average of WCL (24.65%). The females showed higher averages of EE on the breast and ash on the thigh (1.03 and 1.11%, respectively). The IG x NHS and IG x GNJ poultry showed higher averages of EE of the breast (1.21 and 1.38 %, respectively). The poultry of IG breed and those from the crossing with NHS and GNJ presented meat quality characteristics more desirable by the consumer in relation to physicochemical parameters and centesimal composition, while genders showed no influence on these aspects.

Abstract
A sensitive nanocalorimetric technology based on microcantilever sensors is presented. The technology, which combines very short response times with very small sample consumption, uses the bimetallic effect to detect thermal transitions. Specifically, abrupt variations in the Young's modulus and the thermal expansion coefficient produced by temperature changes have been employed to detect thermodynamic transitions. The technology has been used to determine the glass transition of poly(3-thiophene methyl acetate), a soluble semiconducting polymer with different nanotechnological applications. The glass transition temperature determined using microcantilevers coated with ultra-thin films of mass = 10(-13) g is 5.2 °C higher than that obtained using a conventional differential scanning calorimeter for bulk powder samples of mass = 5 × 10(-3) g. Atomistic molecular dynamics simulations on models that represent the bulk powder and the ultra-thin films have been carried out to provide understanding and rationalization of this feature. Simulations indicate that the film-air interface plays a crucial role in films with very small thickness, affecting both the organization of the molecular chains and the response of the molecules against the temperature.

Abstract
Determinou-se a digestibilidade intestinal (DI) da proteína de vários coprodutos do biodiesel nas formas de farelo e torta. Foram avaliados oito coprodutos: tortas e farelos de pinhão manso, nabo forrageiro, tremoço, algodão. Os coprodutos foram incubados no rúmen por 16 horas, e os resíduos não degradados no rúmen submetidos à digestão enzimática com solução de pepsina e pancreatina para a determinação da DI. Ainda, nos resíduos da incubação ruminal, foram determinadas: degradabilidade da matéria seca (DR), proteína degradável no rúmen (PDR) e proteína não degradável no rúmen (PNDR). A digestibilidade intestinal da proteína para os coprodutos do biodiesel variou de 2,4 a 48,6%. Todos os coprodutos avaliados caracterizaram-se como alimentos de alto teor proteico, sendo considerados de alta PDR, e apresentaram baixa digestibilidade intestinal da proteína. A DI da proteína dos coprodutos do biodiesel na forma de torta foi maior em comparação com a dos farelos. A torta e o farelo de algodão apresentaram os maiores coeficientes de DI.

Abstract
This research aims to determine the relationship between the prevalence of caries and clinical and immunological classification in HIV-infected children. Ninety-two outpatients (42 male and 50 female subjects) with definitive diagnosis of HIV infection took part in this research. The patients were examined in order to determine the prevalence of caries (dmf and DMFT indexes), and medical data were collected from their medical records. The mean age of the subjects was 5.77 years. Although no statistical differences were found, young patients (up to 5 years old) had more caries when they were more clinically and immunologically compromised. The same fact was observed regarding older children.

Abstract
We developed the Multi-Track System for percutaneous mitral valvotomy and described the preliminary results in 1995. Here we report the first 100 consecutive cases after the original publication. Two separate balloon catheters are positioned on a single guidewire. The first catheter, with only a distal guidewire lumen, is introduced into the vein and then advanced into the mitral orifice. Subsequently, a rapid exchange balloon catheter running on the same guidewire is inserted and lined up with the first catheter so the two are positioned side by side. Both balloons are then inflated simultaneously. Age of the patients was 31 +/- 12.8 years and weight 50 +/- 14 kg. Valve area increased 0.75 +/- 0.22 cm(2) to 2.00 +/- 0.32 cm(2)and mean left atrial pressure dropped from 27 +/- 8 to 11 +/- 5 mm Hg. One patient had significant mitral insufficiency after dilatation, which did not require surgery. The Multi-Track System is a valid alternative to the existing procedures for the treatment of mitral stenosis and uses simpler and less costly catheters. Cathet. Cardiovasc.

Abstract
A 64-year-old woman is reported with Stage I (Rai) chronic lymphocytic leukaemia (CLL), in whom hypercalcemia developed when an increased proportion of prolymphocytic cells characterized a transformation of CLL in prolymphocytoid leukaemia (CLL/PL). Although hypercalcemia is more frequently found in T-cell leukaemia associated with human T lymphotropic lymphocyte type I, scattered reports indicate that patients with B-CLL can also be affected with this metabolic disturbance. The case described here, progressed with an indolent course of CLL for 26 months, when she was admitted with a very aggressive disease characterized by a high WBC count, splenomegaly and hypercalcemia. Despite an effort to achieve a clinical remission, she failed treatment and death was attributed to unresponsive hypercalcemia. The mechanism of hypercalcemia in such cases is unclear as no parathyroid adenoma or second malignant tumor was found ante mortem. This electrolytic disturbance would appear to be a direct consequence of the transforming leukaemia and a possible mechanism involving a secreted humoral factor that could lead to altered calcium metabolism.
