Differences in toxicology reports and hospital emergency care for patients suspected of experiencing drug-facilitated crimes: an analysis according to gender. / Atención de pacientes con sospecha de sumisión química en un servicio de urgencias hospitalario y resultados del análisis toxicológico: diferencias según el sexo.

OBJECTIVE: To analyze gender-related differences in patient and care characteristics and in toxicology findings in suspected cases of drug facilitated crime (DFC). METHODS: Observational cross-sectional study of all patients in suspected DFC cases attended in the emergency department of Hospital Clínico San Carlos and of their blood or urine samples analyzed by the National institute of Toxicology and Forensics in Madrid between March 1, 2015, and March 1, 2023. We analyzed variables from patient records and the toxicology reports according to gender. RESULTS: A total of 514 suspected DFC episodes were studied; 101 (19.6%) were proactive crimes, 61 (11.9%) opportunistic, and 352 (68.5%) mixed. The median (interquartile range) age was 25 years (21-34 years), and 370 (72%) were women. Eighty-three percent of the patients had amnesia, and 48% of the cases involved sexual assault or robbery. Toxicology identified substances in 78% of the patients (alcohol, 53%; street drugs, 37%; and/or psychopharmaceuticals or opioids, 23%). Independent variables associated with female gender in the multivariate analysis, according to adjusted odds ratio (aORs) were age less than 25 years (aOR, 2.73; 95% CI, 1.75 4.24; P < .001); physician-referred emergency (aOR, 1.77; 95% CI, 1.12-2.80; P = .03); robbery (aOR, 0.25; 95% CI, 0.15-0.41; P < .001); alcohol-positive test result (aOR, 1.91; 95% CI, 1.21-3.00; P = .01); and a drug-positive result (aOR, 0.43; 95% CI, 0.28-0.64; P < .001). Police and a forensic physician intervened in 13% of the cases, and in such cases the victim was more likely to be female (aOR, 3.97; 95% CI, 1.41-11.13; P < .001). Toxicology identified the presence of an unknown substance in 39%, and a woman was less likely to be involved in such cases (aOR, 0.43; 95% CI, 0.28-0.67; P < .001). CONCLUSIONS: The majority of victims of DFCs were female, and the crimes were mixed, involving involve alcohol, psychopharmaceuticals or street drugs. Female victims were more likely to be under the age of 25 years, be referred to the emergency service by a physician, be attended by a forensic physician for sexual assault, and have an alcoholpositive toxicology report. Women were also less likely to report a robbery or have a toxicology report identifying drugs or an unknown substance.

OBJETIVO: Analizar las diferencias en las características de los pacientes atendidos por sospecha de sumisión química (SQ) y en los resultados del análisis toxicológico (AT) en función del sexo. METODO: Estudio observacional transversal retrospectivo que incluyó a todos los casos con SQ atendidos en el servicio de urgencias del Hospital Clínico San Carlos y las muestras (sangre o orina) para el AT en el Instituto Nacional de Toxicología y Ciencias Forenses de Madrid entre el 1 de marzo de 2015 y el 1 de marzo de 2023. Se analizan variables de la historia clínica y del AT según el sexo. RESULTADOS: Se incluyeron 514 episodios con sospecha de SQ [101 (19,6%) proactiva, 61 (11,9%) oportunista y 352 (68,5%) mixta] en pacientes con una mediana de 25 años (RIC: 21-34), 370 (72%) de sexo femenino. El 83% presentó amnesia y el 48% asoció agresión sexual o robo. En el 78% se identificó alguna sustancia en el AT (53% alcohol etílico, 37% drogas y/o 23% psicofármaco u opiáceos). En el análisis multivariado las variables que se asociaron de manera independiente con el sexo femenino fueron la edad menor de 25 años con ORa de 2,73 (IC 95%: 1,75-4,24; p < 0,001), con médico deriva a urgencias con ORa de 1,77 (IC 95%: 1,12-2,80; p = 0,03), delito de robo con de ORa 0,25 (IC 95%: 0,15-0,41; p < 0,001), alcohol etílico en el AT con ORa 1,91 (IC 95%: 1,21-3,00; p = 0,01) y alguna droga en el AT con ORa 0,43 (IC 95%: 0,28-0,64; p < 0,001). En el 13% de casos hubo intervención policial y médico-forense y fue más probable que fuera a una mujer, con ORa 3,97 (IC 95%: 1,41-11,13; p < 0,001). En el 39% de AT se identificó alguna sustancia desconocida y fue menos probable que fuera mujer, con ORa de 0,43 (IC 95%: 0,28-0,67; p < 0,001). CONCLUSIONES: La mayoría de casos registrados fueron mujeres con sospecha de SQ mixta por alcohol, psicofármacos o drogas de abuso. Las mujeres presentaron mayor probabilidad de tener menos de 25 años, ser derivada a urgencias por un médico, de intervención médico-forense por agresión sexual y encontrar alcohol etílico en el AT.

One-Year Changes in Optic Nerve Head Parameters in Recovered COVID-19 Patients.

BACKGROUND: The main purpose was to evaluate the changes in peripapillary retinal nerve fiber layer (RNFL) thickness and vessel density (VD) in post-COVID-19 patients during 12-month follow-up. METHODS: In this prospective study, patients with COVID-19 who were attended in the Hospital Clinico San Carlos (Madrid, Spain) were included. All patients underwent a complete ophthalmological examination, optic nerve head optical coherence tomography (OCT), and OCT angiography (OCTA) using the Cirrus HD-OCT 5,000 with AngioPlex OCTA 1, 3, and 12 months after laboratory-confirmed diagnosis. Sociodemographic data, medical history, disease severity, and laboratory workup were registered. RESULTS: A total of 180 eyes of 90 patients with SARS-CoV-2 infection were included; the mean age was 55.5 ± 8.9 years, and 46 patients (51%) were females. The mean visual acuity was 0.76 ± 0.16, and no abnormalities attributable to SARS-CoV-2 were detected in the ocular or fundus examination. No differences in the OCT and OCTA data were found between severity groups in each visit (all P > 0.05). Overall, there was a decrease in RNFL global thickness ( P < 0.001) from the first to the last visit, and an increase in VD and flux index was noted in some sectors at the 12-month examination. A significant correlation was detected at 12 months between vascularization parameters and RNFL thickness. CONCLUSIONS: One year after SARS-CoV-2 infection, changes in peripapillary RNFL thickness and vascularization occur, possibly indicating a recovery in such parameters.

Optic Nerve Head Vessel Density Assessment in Recovered COVID-19 Patients: A Prospective Study Using Optical Coherence Tomography Angiography.

PRECIS: Vascular diseases have been linked to alterations in optic nerve head perfusion. PURPOSE: The main objective was to investigate the changes in peripapillary vessel density (VD) in post coronavirus disease (COVID-19) patients. METHODS: In this prospective pilot exploratory study, patients with COVID-19 that were attended in the Emergency Department of Hospital Clinico San Carlos (Madrid) were included. All patients underwent optic nerve head optical coherence tomography angiography using the Cirrus HD-OCT 500 with AngioPlex OCTA (Zeiss, Dublin, CA) 4 and 12 weeks after diagnosis by positive reverse transcriptase-polymerase chain reaction test from nasopharyngeal swab at the Emergency Department. Sociodemographic data, medical history, disease severity, and laboratory work-up were collected. RESULTS: One hundred and eighty eyes of 90 patients with severe acute respiratory syndrome-coronavirus-2 (SARS-CoV-2) infection were included. None of the patients reported visual changes. Severe patients were older, more frequently hispanic, dyslipidemic, and presented lower lymphocytes counts, as well as increased ferritin, D-dimer, fibrinogen, and international normalized ratio levels. No changes in optic nerve head vascularization were observed when both visits were compared. No correlation was found between VD and clinical parameters, disease severity and laboratory work-up. CONCLUSIONS: Changes to peripapillary VD were not observed in patients with COVID-19 in the early months following diagnosis.

Diabetic ketoacidosis inducing myocardial infarction secondary to treatment with dapagliflozin: a case report.

Sodium-glucose cotransporter 2 (SGLT2) inhibitors are able to provoke diabetic ketoacidosis (DKA) with absence or low levels of ketone bodies in urine and slightly elevated blood glucose levels, which could delay the diagnosis; however, the presence of high urine output, due to the excretion of glucose, can help to identify the true cause.

Functional status and inflammation after preseason training program in professional and recreational soccer players: a proteomic approach.

The purpose of the study was to determine if an intensive pre- season training program modifies the inflammatory status in professional soccer players and if this inflammatory profile may be associated with the physical state. We compared plasma protein biomarkers, using proteomics, and the physiological state and cardiac function in 12 professional soccer players and 9 recreational soccer players. Reduced cardiac low frequency [LF] after the pre- season training program previous competition with respect to recreational soccer players was found. No differences were found in cardiac high frequency, cardiac high frequency/low frequency ratio, tension index and oxygen volume consumption. Alpha-1-antitrypsin isotype-3, fibrinogen-gamma isotypes-1, 2 and 3 and vitamin-D-binding protein isotype-1 were reduced in professionals players compared with those in recreational players. However, an increased content of alpha-1-antitrypsin isotype-6 and alpha-1-antichymotrypsin 1 and 4 were found in professional soccer players. Spearman's analysis showed a positive correlation between LF and fibrinogen-gamma chain isotype 3; but LF was negatively correlated with alpha-antichymotrypsin isotype 4. Professional soccer players submitted to an intensive training showed differences in the content of plasma proteins associated with inflammatory/oxidative stress and thrombosis with respect to recreational soccer players. Proteomics analysis in combination with the analysis of cardiac function assessment may be useful to know more in depth molecular processes associated with sport and intensive exercise. Key pointsProteomics allow us to find differences in the plasma protein content in sportsmen.Just after pre-season training program, professional soccer players showed lower content of circulating proteins associated with inflammation compared to recreational soccer players.Proteomic analysis in combination with the analysis of cardiac function may be useful to know more in depth molecular inflammatory and oxidative processes associated with the sport.

Different protein expression in normal and dysfunctional platelets from uremic patients.

Although many uremic patients show platelet dysfunctionality, there are others with normal platelet functionality and even with thrombotic tendencies. Our aim was to evaluate changes in the expression of proteins in functional and dysfunctional uremic platelets. Using the platelet function analyzer (PFA-100) assay, uremic patients were divided according to their platelet functionality into normal (n=7) and dysfunctional (n=8). There were no significant differences in the number of circulating platelets and hematocrit and hemoglobin levels. Two-dimensional electrophoresis and mass spectrometry were used to determine and identify changes in protein expression. The closure time (CT) in the PFA-100 assay was significantly prolonged in the dysfunctional uremic platelets. In the dysfunctional platelets, actin-interacting protein-1 isotype 1 was down-regulated, while integrin IIb was up-regulated. Glutathione-S-transferase isotypes 1 and 2 and peroxiredoxin VI were up-regulated in the dysfunctional platelets. Pearson analysis showed a negative correlation between the platelet expression of integrin IIb and creatinine clearance. A positive correlation was found between creatinine clearance and glutathione-S-transferase isotype 2. Serum uric acid concentration was positively correlated with CT values and glutathione-S-transferase isotype 1. In conclusion, the analysis of the protein expression in uremic platelets with normal and dysfunctional activity revealed differences which may occur at the megakaryocyte level.

Effect of parathyroid-hormone-related protein on human platelet activation.

Evidence suggests that PTHrP [PTH (parathyroid hormone)-related protein] can act as an inflammatory mediator in several pathological settings including cardiovascular disease. The aim of the present study was to determine whether PTHrP might be involved in human platelet activation. We used a turbidimetric method to determine platelet aggregation. The expression of PTH1R (PTH type 1 receptor) in human platelets was analysed by Western blot and flow cytometry analyses. PTHrP-(1-36) (10(-7) mol/l) by itself failed to modify the activation of platelets. However, it significantly enhanced ADP-induced platelet activation, and also increased the ability of other agonists (thrombin, collagen and arachidonic acid) to induce platelet aggregation. H89 (10(-6) mol/l) and 25 x 10(-6) mol/l Rp-cAMPS (adenosine 3',5'-cyclic monophosphorothioate Rp-isomer), two protein kinase A inhibitors, and 25 x 10(-9) mol/l bisindolylmaleimide I, a protein kinase C inhibitor, partially decreased the enhancing effect of PTHrP-(1-36) on ADP-induced platelet activation. Meanwhile, 10(-6) mol/l PTHrP-(7-34), a PTH1R antagonist, as well as 10(-5) mol/l PD098059, a MAPK (mitogen-activated protein kinase) inhibitor, or a farnesyltransferase inhibitor abolished this effect of PTHrP-(1-36). Moreover, 10(-7) mol/l PTHrP-(1-36) increased (2-fold over control) MAPK activation in human platelets. PTH1R was detected in platelets, and the number of platelets expressing it on their surface in patients during AMI (acute myocardial infarction) was not different from that in a group of patients with similar cardiovascular risk factors without AMI. Western blot analysis showed that total PTH1R protein levels were markedly higher in platelets from control than those from AMI patients. PTH1R was found in plasma, where its levels were increased in AMI patients compared with controls. In conclusion, human platelets express the PTH1R. PTHrP can interact with this receptor to enhance human platelet activation induced by several agonists through a MAPK-dependent mechanism.
