RESUMO

In this research, a molecularly imprinted polymer (MIP) was synthesized by precipitation polymerization using oxazepam (OZ) as a template molecule and was subsequently applied as a selective sorbent for the extraction of diazepam (DZP) and its metabolites in urine samples using an SPE cartridge. OZ, temazepam (TZ), nordiazepam (NZ) and DZP were analyzed in the final extracts by high-performance liquid chromatography with diode array detection (HPLC-DAD). The SPE extraction steps were optimized, and the evaluation of an imprinting factor was carried out. The selectivity of the method for OZ versus structurally related benzodiazepines (BZDs), such as bromazepam (BRZ), tetrazepam (TTZ) and halazepam (HZ), was investigated. Under the optimum conditions, the proposed methodology provided good linearity in the range of 10-1500 ng/mL, with limit of detection values between 13.5 and 21.1 ng/mL and recovery levels for DZP and its metabolites from 89.0 to 93.9% (RSD ≤ 8%) at a concentration level of 1000 ng/mL. The proposed method exhibited good selectivity, precision and accuracy and was applied to the analysis of urine samples from a real case of DZP intake.

RESUMO

The information and subsequent expression of will, so-called informed consent, have become the essential element of health right, understood as the right to autonomous choice in health, based on the fiduciary relationship between physician and patient. This gradually leads European Countries to adopt special legislations and to issue frequent judgments on the subject. However, new challenges in daily clinical practice call for further study of legal solutions. The authors analyse and compare the regulations on informed consent in health care of Italy, France, the United Kingdom, the Nordic Countries, Germany, and Spain. The health and legal contexts, existence of special regulations on informed consent and their characteristics are discussed. Informed consent resulted a mandatory requirement. Clear communication about treatment, therapeutic alternatives, and major risks, discussed in conversation, but preferably documented in writing, are agreed upon. The possibility of dissent and withdrawal of consent are also included. There is a growing interest in involving and regulating the entire health team in information and consent. Lowering the age of consent for minors or analysing the maturity of minors are attempts to increase their participation in health decisions. On another side, the protection of adult incapables persons requires greater involvement of family and fiduciaries to better adapt to changing health needs. Health policy must take responsibility for training health professionals and citizens about the value of health information and communication as a shared choice in care planning, to strengthen the bond of trust with the healthcare system and users.

RESUMO

BACKGROUND: With more than 7500 cases reported since April 2022, Spain has experienced the highest incidence of mpox in Europe. From 12 July onward, the modified vaccinia Ankara-Bavaria Nordic (MVA-BN) smallpox vaccine was offered as pre-exposure prophylaxis for those receiving pre-exposure prophylaxis for human immunodeficiency virus (HIV-PrEP). Our aim was to assess the effectiveness of 1 dose of MVA-BN vaccine as pre-exposure prophylaxis against mpox virus (MPXV) infection in persons on HIV-PrEP. METHODS: National retrospective cohort study between 12 July and 12 December 2022. Individuals aged ≥18 years receiving HIV-PrEP as of 12 July with no previous MPXV infection or vaccination were eligible. Each day, we matched individuals receiving a first dose of vaccine and unvaccinated controls of the same age and region. We used a Kaplan-Meier estimator, calculated risk ratios (RR) and vaccine effectiveness (VE = [1 - RR]x100). RESULTS: We included 5660 matched pairs, with a median follow-up of 62 days (interquartile range, 24-97). Mpox cumulative incidence was 5.6 per 1000 (25 cases) in unvaccinated and 3.5 per 1000 (18 cases) in vaccinated. No effect was found during days 0-6 post-vaccination (VE, -38.3; 95% confidence interval [CI], -332.7 to 46.4), but VE was 65% at ≥7 days (95% CI, 22.9 to 88.0) and 79% at ≥14 days (95% CI, 33.3 to 100.0) post-vaccination. CONCLUSIONS: One dose of MVA-BN vaccine offered protection against mpox in most-at-risk population shortly after the vaccination. Further studies need to assess the VE of a second dose and the duration of protection over time.

RESUMO

Patients with chronic diarrhoea or ileostomies suffer from electrolyte and urinary disorders and are prone to developing uric acid or calcium oxalate stones. Evidence is lacking regarding the management of uric acid stones in patients with inflammatory bowel diseases. We present the case of a male patient with Crohn's disease and carrying an ileostomy. He was diagnosed with uric acid urolithiasis (stone size of 11 mm located in the left pyeloureteral junction) after presenting to the emergency room during an episode of left renal colic. Results of the 24-hour urinalysis showed an acidic pH (pH <5), consistent with hyperuricosuria. The suspicion of uric acid lithiasis was confirmed after performing an X-ray diffraction analysis of a lithiasic fragment that passed during acute renal colic. The patient was prescribed with urinary alkalinisers (medical treatment) and dietary recommendations. After 12 months of treatment and urine pH monitoring, the patient achieved complete chemolysis while maintaining the stability of his underlying Crohn's disease. The patient had no complications during follow-up, referring adequate gastrointestinal tolerance to treatment and denying side effects. The patient remains asymptomatic and is being followed-up on an outpatient basis. He continues on prophylactic treatment (Lit-Control® pH Up) to maintain the pH in the non-acidic range.

RESUMO

BACKGROUND: Post-mortem imaging has been suggested as an alternative to conventional autopsy in the prenatal and postnatal periods. Noninvasive autopsies do not provide tissue for histological examination, which may limit their clinical value, especially when infection-related morbidity and mortality are suspected. METHODS: We performed a prospective, multicentre, cross-sectional study to compare the diagnostic performance of post-mortem magnetic resonance imaging with computed tomography-guided biopsy (Virtopsy®) with that of conventional autopsy in foetuses and infants. Cases referred for conventional autopsy were eligible for enrolment. After post-mortem imaging using a computed tomography scanner and a magnetic resonance imaging unit, computed tomography-guided tissue sampling was performed. Virtopsy results were compared with conventional autopsy in determining the likely final cause of death and major pathologies. The primary outcome was the proportion of cases for which the same cause of death was determined by both methods. Secondary outcomes included the proportion of false positive and false negative major pathological lesions detected by virtopsy and the proportion of computed tomography-guided biopsies that were adequate for histological examination. RESULTS: Overall, 101 cases (84 fetuses, 17 infants) were included. Virtopsy and autopsy identified the same cause of death in 91 cases (90.1%, 95% CI 82.7 to 94.5). The sensitivity and specificity of virtopsy for determining the cause of death were 96.6% (95% CI 90.6 to 98.8) and 41.7% (95% CI 19.3 to 68.0), respectively. In 32 cases (31.7%, 95% CI 23.4 to 41.3), major pathological findings remained undetected by virtopsy, and in 45 cases (44.6%, 95% CI 35.2 to 54.3), abnormalities were diagnosed by virtopsy but not confirmed by autopsy. Computed tomography-guided tissue sampling was adequate for pathological comments in 506 of 956 biopsies (52.7%) and added important diagnostic value in five of 30 cases (16.1%) with an unclear cause of death before autopsy compared with postmortem imaging alone. In 19 of 20 infective deaths (95%), biopsies revealed infection-related tissue changes. Infection was confirmed by placental examination in all fetal cases. CONCLUSIONS: Virtopsy demonstrated a high concordance with conventional autopsy for the detection of cause of death but was less accurate for the evaluation of major pathologies. Computed tomography-guided biopsy had limited additional diagnostic value. TRIAL REGISTRATION: ClinicalTrials.gov (NCT01888380).

RESUMO

Microplastic (MP) ingestion, along with accumulated plasticizers such as bisphenol A (BPA), bisphenol F (BPF), and bisphenol S (BPS), and phthalates represented by diethyl phthalate (DEP), dibutyl phthalate (DBP) and bis (2-ethylhexyl) phthalate (DEHP), were quantified in bivalves, fish, and holothurians collected from a coastal pristine area at the western Mediterranean Sea. MP ingestion in sediment-feeders holothurians (mean value 12.67 ± 7.31 MPs/individual) was statistically higher than ingestion in bivalves and fish (mean 4.83 ± 5.35 and 3 ± 4.44 MPs/individual, respectively). The main ingested polymers were polyethylene, polypropylene, and polystyrene. The levels of BPS, BPF, and DEHP were highest in bivalves' soft tissue; BPA and DBP had the highest levels in the holothurians' muscle. In addition, the levels of all plasticizers assessed were lowest in fish muscle; only BPA levels in fish were higher than in bivalves, with intermediate values between those of bivalves and holothurians. This study provides data on exposure to MPs and plasticizers of different species inhabiting Cabrera Marine Protected Area (MPA) and highlights the differences in MP ingestion and levels of plasticizers between species with different ecological characteristics and feeding strategies.

RESUMO

INTRODUCTION: The association between preeclampsia and coronavirus disease 2019 (COVID-19) is under study. Previous publications have hypothesized the existence of shared risk factors for both conditions or a deficient trophoblastic invasion as possible explanations for this association. The primary aim of this study was to examine baseline risk factors measured in the first-trimester combined screening for preeclampsia in pregnant women with COVID-19 compared with the general population. A secondary aim of this study was to compare risk factors among patients with mild and severe COVID-19. MATERIAL AND METHODS: This was an observational retrospective study conducted at Vall d'Hebron Hospital Campus (Catalonia, Spain). Study patients were 231 pregnant women undergoing the first-trimester screening for preeclampsia and positive for severe acute respiratory syndrome coronavirus 2 between February 2020 and September 2021. The reference cohort were 13 033 women of the general population from six centers across Catalonia from May 2019 to June 2021. Based on the need for hospitalization, patients were classified in two groups: mild and severe COVID-19. First-trimester screening for preeclampsia included maternal history, mean arterial blood pressure, mean uterine artery pulsatility index (UtAPI), placental growth factor (PlGF), and pregnancy-associated plasma protein-A (PAPP-A). RESULTS: The proportion of cases at high risk for preeclampsia was significantly higher among the COVID-19 group compared with the general population (19.0% and 13.2%, respectively; p = 0.012). When analyzing risk factors for preeclampsia individually, women with COVID-19 had higher median body mass index (25.2 vs 24.5, p = 0.041), higher UtAPI multiple of the median (MoM) (1.08 vs 1.00, p < 0.001), higher incidence of chronic hypertension (2.8% vs 0.9%, p = 0.015), and there were fewer smokers (5.7% vs 11.6%, p = 0.007). The MoMs of PlGF and PAPP-A did not differ significantly between both groups (0.96 vs 0.97, p = 0.760 and 1.00 vs 1.01, p = 0.432; respectively). CONCLUSIONS: In patients with COVID-19, there was a higher proportion of women at high risk for preeclampsia at the first-trimester screening than in the general population, mainly because of maternal risk factors, rather than placental signs of a deficient trophoblastic invasion.

RESUMO

Marine aquaculture is considered a potential source of microplastics (MPs). MPs can induce oxidative stress and damage in marine species. In this study we evaluated the impact of MPs intake in the commercial fish, Sparus aurata, from aquaculture facilities and the antioxidant response associated to this MPs ingestion in caged specimens for 120 days. Sampling was carried out at the beginning of the study (T0), at 60 days (T60) and at 120 days (T120). At each sampling stage, gastrointestinal tract, blood, plasma, liver and muscle samples were obtained to analyse MPs intake (gastrointestinal tract), oxidative stress markers (blood, plasma and liver) and plasticizers bioaccumulation (muscle). Fish sampled at T60 presented the highest MPs intake and plasticizers accumulated in muscle over time, but with a different pattern according to type: bisphenols and phthalates. This indicates MPs ingestion induces a differential tissue response in S. aurata. Similarly, stress biomarkers presented a differential response throughout the study, depending on the analysed tissue. In the case of oxidative damage markers, for malondialdehyde (MDA) an increase throughout the study was observed both in liver and blood cells but with a progressive decrease in plasma. In the case of phase I detoxifying enzyme activities in liver, 7-ethoxyresorufin O-deethylase (EROD), 7-benzyloxy-4-[trifluoromethyl]-coumarin-O-debenzyloxylase (BFCOD) and carboxylesterases (CE), showed a comparable decrease at T60 with a slight recovery at T120. In contrast, glutathione-S-transferase (GST) activity was significantly enhanced at T60 compared to the other sampling stages. In conclusion, MPs ingestion occurs in aquaculture reared seabream where potentially associated plasticizers accumulate in the muscle and both could be responsible for plasma and liver oxidative stress damage and alterations on detoxifying biomarkers responses.

RESUMO

The growing plastic production and its continuous use is a significant problem. In addition, aquaculture practices have experienced a considerable growth and plastic is widely used in these activities, hence plasticizers must be considered due to their potential ecotoxicological impacts on species. Mussels placed inside an Integrated Multi-Trophic Aquaculture (IMTA) system and at two control locations were employed to quantify the ingestion of anthropogenic particles and associated chemical plasticizers, such as bisphenol A (BPA) jointly to bisphenol F (BPF) and bisphenol S (BPS), and phthalates represented by diethyl phthalate (DEP), dibutyl phthalate (DBP) and bis(2-ethylhexyl) phthalate (DEHP). In addition, some metabolism and oxidative stress related parameters were measured in mussels' whole soft tissue. Anthropogenic particle ingestion of mussels increased over time at the three locations and the following order of abundance of pollutants was observed: BPA> BPF> DEHP> DBP> BPS> DEP. Even though no differences according to location were found for pollutants' occurrence, time trends were evidenced for BPA and DEHP. On the other hand, a location effect was observed for biomarkers with highest values detected in mussels located at the vicinities of the aquaculture facility. In addition, a reduced detoxification activity was observed over time parallel to BPA decrease.

RESUMO

In Spain, health competencies are decentralized, and each autonomous community implements its own plans. Our aim is to determine if the existence of regional palliative care plans implies an improvement in health care coverage. We reviewed regional palliative care plans published in Spain and analyzed the following variables: number and profile of palliative care resources, guidelines and objectives of implementation of resources of these plans, and compliance with European standards. The publication of regional plans is associated with an increase in specific resources in the following years. From 2004 to 2009, the implementation of plans in 6 autonomous communities was associated with an increase in palliative care resources compared to those without a strategy (odds ratio: 1.58, P = .02) or with a settled plan (odds ratio: 1.40, P = .07). The same phenomenon was observed between 2009 and 2015 in 4 autonomous communities and 2 autonomous cities compared with those without a strategy (odds ratio: 2.49, P = .001) and those that implemented a plan before 2009 (odds ratio: 2.62, P < .001). Updating and evaluating these regional plans are also associated with the growth of palliative care resources.

RESUMO

El absceso hepático piógeno es una patología que aún en nuestros días supone un reto médico, ya que su curso clínico suele ser grave, el diagnóstico frecuentemente tardío y la mortalidad elevada. En las últimas décadas hemos asistido a diversos avances, como la introducción de los antibióticos de amplio espectro y el desarrollo de técnicas de imagen e intervencionistas que han mejorado la eficacia diagnóstica y el pronóstico de esta patología. Pese a ello, la presencia de abscesos hepáticos piógenos múltiples no es una patología superada y presentamos un caso clínico que ilustre esta patología y justifique que ha de tenerse en cuenta en el arsenal diagnóstico para poder tratarlo precozmente y disminuir así su alta morbimortalidad.

Pyogenic liver abscess is a pathology that still poses a medical challenge today, since its clinical course is usually severe, diagnosis is often late, and mortality is high. In recent decades we have witnessed several advances, such as the introduction of broad-spectrum antibiotics and the development of imaging and interventional techniques that have improved the diagnostic efficacy and prognosis of this pathology. Despite this, the presence of multiple pyogenic liver abscesses is not a pathology that has been overcome and we present a clinical case that illustrates this pathology and justifies that it must be considered in the diagnostic arsenal in order to treat it early and thus reduce its high morbimortality.

RESUMO

Emotions are a fundamental part of mental health and human behavior. In the workplace, optimal performance of employees is necessary for productivity enhancements and its relation to the quality of a manufacturing product, therefore leading a company to advantages and competitiveness. This means that the workplace staff must remain in a neutral or a calm emotional state, for an adequate job performance. When an operation is not pleasant or the same task is carried out for a long period of time (repetitive), it can cause negative emotions such as stress, and this will have repercussions in poor work performance. The purpose of this research is, by means of an electroencephalogram (EEG), to identify the stress in the repetitive assembly of a manufacturing product. To measure brain waves, the Emotiv Epoc equipment was used and a manufacturing line was designed, divided into three workstations, where the assembly of product comprising a LEGO car was carried out within a manual repetitive approach. The appearance of stress was determined by employing two different methodologies, the prefrontal relative gamma marker (RG) and the valence, arousal, and dominance (VAD) emotional categories. The results obtained from the first methodology, corresponding to the RG marker, displayed a significant more change between the relaxation state and the product assembly carried out at 70% of the standard time (ST). A less significant change was observed between the relaxation state and the product assembly carried out at 100% ST, thus signaling the presence of stress. Additionally, the results from the VAD methodology resulted in moderate and low levels of stress, when the product assembly was carried out at 70% and 100% standard time, respectively.

RESUMO

Elevated plasma bilirubin levels are a frequent clinical finding. It can be secondary to alterations in any stage of its metabolism: (a) excess bilirubin production (i.e., pathologic hemolysis); (b) impaired liver uptake, with elevation of indirect bilirubin; (c) impaired conjugation, prompted by a defect in the UDP-glucuronosyltransferase; and (d) bile clearance defect, with elevation of direct bilirubin secondary to defects in clearance proteins, or inability of the bile to reach the small bowel through bile ducts. A liver lesion of any cause reduces hepatocyte cell number and may impair the uptake of indirect bilirubin from plasma and diminish direct bilirubin transport and clearance through the bile ducts. Various analytical methods are currently available for measuring bilirubin and its metabolites in serum, urine and feces. Serum bilirubin is determined by (1) diazo transfer reaction, currently, the gold-standard; (2) high-performance liquid chromatography (HPLC); (3) oxidative, enzymatic, and chemical methods; (4) direct spectrophotometry; and (5) transcutaneous methods. Although bilirubin is a well-established marker of liver function, it does not always identify a lesion in this organ. Therefore, for accurate diagnosis, alterations in bilirubin concentrations should be assessed in relation to patient anamnesis, the degree of the alteration, and the pattern of concurrent biochemical alterations.

RESUMO

Modern agriculture demands for more sustainable agrochemicals to reduce the environmental and health impact. The whole process of the discovery and development of new active substances or control agents is sorely slow and expensive. Vegetative insecticidal proteins (Vip3) from Bacillus thuringiensis are specific toxins against caterpillars with a potential capacity to broaden the range of target pests. Site-directed mutagenesis is one of the most approaches used to test hypotheses on the role of different amino acids on the structure and function of proteins. To gain a better understanding of the role of key amino acid residues of Vip3A proteins, we have generated 12 mutants of the Vip3Af1 protein by site-directed mutagenesis, distributed along the five structural domains of the protein. Ten of these mutants were successfully expressed and tested for stability and toxicity against three insect pests (Spodoptera frugiperda, Spodoptera littoralis and Grapholita molesta). The results showed that, to render a wild type fragment pattern upon trypsin treatment, position 483 required an acidic residue, and position 552 an aromatic residue. Regarding toxicity, the change of Met34 to Lys34 significantly increased the toxicity of the protein for one of the three insect species tested (S. littoralis), whereas the other residue substitutions did not improve, or even decreased, insect toxicity, confirming their key role in the structure/function of the protein.

RESUMO

INTRODUCTION: Several algorithms for first-trimester screening for preeclampsia are available; however, the Gaussian model algorithm is more likely to match the characteristics of different populations. It is recommended to validate a screening strategy before being implemented in clinical practice; unfortunately, the validation process might not be feasible in all settings. Thus, the aim of this study was to provide cut-off values for the Gaussian model for its use in clinical practice. MATERIAL AND METHODS: This prospective cohort study was conducted at Vall d'Hebron University Hospital (Barcelona) from October 2015 to September 2017. A total of 2641 women with singleton pregnancies were recruited. Recorded at the first-trimester scan were demographic characteristics, maternal obstetric history, maternal history, uterine artery Doppler and arterial blood pressure. Serum concentrations of pregnancy-associated plasma protein-A and placental growth factor were assessed from the first-trimester blood test. Detection rates and cut-off values for fixed 5%, 10 %, 15 %, 20 %, 25 % and 30 % false-positive rates were calculated for all combinations of markers. RESULTS: Ninety (3.41 %) of the 2641 women developed preeclampsia, which was early-onset in 11 (0.42 %). The cut-off values and their respective detection rates, for the screening of early-onset PE by all possible combinations of markers involved in this model, are provided. DISCUSSION: When external validation of first-trimester screening for preeclampsia before its clinical implementation is not feasible, the cut-off values from the Gaussian model algorithm provided in this study could be used and median values corrected prospectively if necessary.

RESUMO

In the present study we evaluate the population structure and potential colonization routes of the silverside Chirostoma humboldtianum through approximate Bayesian computations. Six microsatellite loci were amplified in a total of 288 individuals from six different locations covering the complete geographic distribution of the species. Additionally, two mitochondrial DNA markers, a D loop control region and cytochrome b were amplified in a subset of 107 individuals. The results found with microsatellites allow recovering well-structured populations that have experienced a drastic reduction in the effective population size. On the other hand, mtDNA sequences showed a moderate phylogeographic structure with shared haplotypes between geographic localities and signalsof a slight increase in the effective population size. Finally, the approximate Bayesian computation analysis performed with both datasets suggested a west-to-east colonization route for the species in Central Mexico.

RESUMO

PURPOSE: The detection and quantification of metabolites relevant for the diagnosis of fatal metabolic disorders by proton magnetic resonance spectroscopy (1H-MRS) was recently demonstrated. This prospective study aimed to compare the concentrations of beta-hydroxybutyrate (BHB), glucose (GLC), and lactate (LAC) derived from both biochemical analyses and 1H-MRS for the diagnosis of fatal metabolic disorders. METHODS: In total, 20 cases with suspected fatal metabolic disorders were included in the study. For the agreement based on thresholds, the concentrations of BHB and GLC in the vitreous humor (VH) from the right vitreous and in cerebrospinal fluid (CSF) from the right lateral ventricle were derived from 1H-MRS and biochemical analyses. The predefined thresholds for pathological elevations were 2.5 mmol/l for BHB and 10 mmol/l for GLC based on the literature. In addition, concentrations of the same metabolites in white matter (WM) tissue from the corona radiata of the right hemisphere were analyzed experimentally using both methods. To enable the biochemical analysis, a dialysate of WM tissue was produced. For all three regions, the LAC concentration was determined by both methods. RESULTS: The conclusive agreement based on thresholds was almost perfect between both methods with only one disagreement in a total of 70 comparisons due to the interference of a ferromagnetic dental brace. The differences in the concentrations between both methods showed high standard deviations. Confidence intervals of the bias not including 0 were found in CSF-GLC (- 3.1 mmol/l), WM-GLC (1.1 mmol/l), and WM-LAC (- 6.5 mmol/l). CONCLUSION: Despite a considerable total error attributable to both methods, MRS derives the same forensic conclusions as conventional biochemical analyses. An adaptation of the protocol to reduce the detected errors and more data are needed for the long-term validation of MRS for the diagnosis of fatal metabolic disorders. The production of WM dialysates cannot be recommended due to high glycolytic loss.

RESUMO

OBJETIVOS: Los cuidados paliativos (CP) forman parte de las transferencias de salud que asumieron las comunidades autónomas (CCAA). Nos planteamos describir las características principales de las estrategias regionales de CP que se han publicado hasta la fecha. MÉTODO: Revisión de los planes, programas o estrategias de CP de las CCAA y las ciudades autónomas de Ceuta y Melilla publicadas desde 2002 a 2018. La búsqueda se ha llevado a cabo en los sitios web de las consejerías y planes de salud de las CCAA y se ha complementado con el Observatorio de CP de Castilla y León. Variables analizadas: fechas y versiones, cronograma, perfil de los redactores, estructura del plan, objetivos, líneas estratégicas, evaluación y organización. RESULTADOS: Hasta enero de 2018 son 15 las CCAA que han publicado su Plan Estratégico de CP, además del de Ceuta y Melilla. Cuatro han editado una actualización del Plan y en la actualidad solo están en vigor tres de las estrategias de las que definían un cronograma o periodo de aplicación. Solo dos han presentado datos de evaluación. La proporción de profesionales de CP en la composición del grupo redactor varía mucho. La estructura general de los documentos es similar y el objetivo principal es común: la mejora de la calidad de vida de los pacientes terminales y sus familias. Casi todos los planes asumen varias de las líneas estratégicas propuestas por los Planes Nacionales de 2001 y 2007. Seis CCAA incluyen también la mejora de los sistemas de información y registro y la participación de la comunidad. El modo de plantear la organización de la atención en CP presenta una gran variabilidad. Aunque la mayor parte de las CCAA diferencia equipos hospitalarios y de atención domiciliaria, se aprecia una tendencia a integrar estos recursos. CONCLUSIONES: Los objetivos generales de los planes son similares y responden a las líneas del Plan Nacional. Sin embargo, hay heterogeneidad en el diseño, planteamiento y organización de los programas de CP. Se aprecian carencias en la actualización y evaluación de los planes


OBJECTIVES: Palliative care (PC) has been taken on by the Spanish Autonomous Communities (ACs) as part of the central government's transfer of healthcare competencies to regional institutions. We describe the main characteristics of the PC strategies reported by ACs to this day. METHOD: A review of all PC plans, programs and strategies reported from 2002 through 2018 by the Spanish ACs and autonomous cities of Ceuta and Melilla. A search was performed of the websites of AC ministries and health plans, supplemented by the PC Observatory of Castilla y León. Assessed variables included: dates and versions, chronogram, author profiles, structure, objectives, strategic lines, evaluation, and organization. RESULTS: Through January 2018, 15 ACs published their PC Strategic Plans, in addition to Ceuta and Melilla. Four ACs have published updates of their Plans, and to date only three of those with a predefined period for implementation are active. Only two have reported evaluation data. The proportion of PC professionals in the composition of the drafting groups varies. The documents have similar structures and a common primary objective: improving quality of life for terminal patients and their families. Almost all Plans endorse several of the strategic lines proposed by the National Plans for 2001 and 2007. Six ACs also contemplate improvements in their information and recording systems, as well as in community participation. Organizational designs vary extensively regarding PC; while most ACs differentiate between hospital and home care teams, there is a tendency to integrate these resources. CONCLUSIONS: The primary objectives of AC Plans are similar and aligned with the National Plan. However, there is heterogeneity in the design, planning and organization of PC programs. Deficiencies in the updating and evaluation of these Plans also exist

RESUMO

Occasional case reports have described isolated cases of conducted electrical weapon (CEW) probes piercing the human skull. In an experimental setting, we examined whether these cases were just unfortunate incidents, how deeply such probes can pierce the skull, and whether firing distance and CEW probe type play a role in the skull-piercing capability.We fired 5 different CEW cartridges (XP 10.6 m, XP 7.6 m, smart 10.6 m, smart 7.6 m, and smart probe 7.6 m) from 4 different distances (0.5, 1, 2, and 4 m) at head phantoms made of either 5- or 7-mm-thick polyurethane spheres covered with a thin layer of gelatine and buckskin. The piercing depths were recorded by computed tomographic scanning.All tested cartridges managed to pierce the head phantoms. Piercing depths of up to 6.6 mm in the 5-mm heads and depths of almost 5 mm in the 7-mm heads were recorded. Deepest piercing depths were attained with firing distances of 2 m or less.Our results showed that all tested CEW probes are capable of piercing the skull and that shorter firing distances tend to lead to deeper piercing depths.

RESUMO

Postmortem CT for investigating childhood deaths is increasingly utilised as a noninvasive adjunct or alternative to standard autopsy; however there are no standardised published imaging protocols. This article describes a standardised imaging protocol that has been developed based on current practices of international postmortem imaging practitioners and experts. This recommendation is expected to be useful for postmortem imaging centres wishing to update their existing practices and for those starting paediatric postmortem CT as a new service.
