RESUMO

OBJECTIVES: To detect the presence of unsuspected and/or undeclared cathinone and piperazine-type designer drugs in methamphetamine (METH) and amphetamine users treated in emergency departments, and to compare clinical and toxicologic profiles. MATERIAL AND METHODS: Retrospective observational study of emergency department patients treated for confirmed acute intoxication by recreational drugs (METH and amphetamines) between March 2019 and December 2020. We ordered high-performance liquid chromatography with tandem mass spectrometry to detect cathinones (methylone, fluoromethcathinone, mexedrone, fluoromethamphetamine, mephedrone, methylenedioxypyrovalerone) and synthetic piperazines (meta-chlorophenylpiperazine and trifluoromethylphenylpiperazine). Demographic, clinical, and toxicologic variables were analyzed with SPSS software (version 23). RESULTS: Thirty-nine patients were included: 24 (61.5%) had used METH and 15 (38.5%) an amphetamine. Synthetic cathinones were detected in samples from 11 patients (28.2%), 10 (90.9%) in the METH group and 1 (9.1%) in the amphetamine group (P = .028). The METH users had taken mephedrone (8 patients) or methylone (2 patients); the amphetamine user had taken mephedrone. None of the patients had declared use of a cathinone; nor was use suspected. The mean (SD) number of substances involved was higher among users of cathinones (3.5 [1.13] vs 2.5 [1.40] in those who took no cathinones; P = .036). Among the cathinone users, 90.9% were men, 90.9% had used METH, and 45.5% had practiced chemsex. HIV positivity was significantly associated with cathinone use (in 45.5% vs 10.7% of those not using cathinones; P = .028). All 5 of the patients who had taken cathinones and also practiced chemsex were HIV positive. Significantly more patients who had taken cathinones presented with anxiety (72.7% vs 21.43%; P = .007). No differences in clinical management were found. CONCLUSION: Detection of METH in intoxicated patients should raise suspicion of probable use of a synthetic cathinone. Patients in whom new psychoactive substances are detected should be kept under observation, and clinical protocols should include referring them to addiction treatment centers.


OBJETIVO: Determinar la incidencia de catinonas y piperazinas, no sospechadas y/o declaradas en consumidores de metanfetamina (MANF) y anfetamina (ANF) atendidos en servicios de urgencias hospitalarios (SUH) y comparar los perfiles clínicos y toxicológicos. METODO: Estudio retrospectivo de pacientes con intoxicación aguda por drogas recreativas con MANF y ANF confirmadas analíticamente atendidos en 3 SUH entre marzo de 2019 y diciembre de 2020. Se detectaron por HPLC-MS/MS las catinonas [metilona, fluorometcatinona, mecedrona, fluorometanfetamina, mefedrona, metilendioxipirovalerona (MDPV)] y las piperazinas sintéticas [meta-clorofenilpiperazina (mCPP), trifluorometilfenilpiperazina (TFMPP)]. RESULTADOS: Se incluyeron 39 pacientes: 24 (61,5%) en el grupo MANF y 15 (38,5%) en el ANF. En 11 (28,2%), se detectaron catinonas sintéticas (grupo CAT), 10 en el grupo MANF (8 mefedrona, 2 metilona) y 1 en el grupo ANF (1 mefedrona) (90,9% vs 9,1%; p = 0,028). Ninguno de los pacientes declaró consumo de catinonas. El número de drogas implicadas en la intoxicación fue superior en el grupo CAT (3,5 [1,13] vs 2,5 [1,40]; p = 0,036). El perfil clínico del grupo CAT fue: varón (90,9%), consumidor de MANF (90,9%) y usuario de chemsex (45,5%). El diagnóstico de VIH se asoció significativamente al grupo CAT (45,5% vs 10,7%; p = 0,028). Los pacientes del grupo CAT presentaron mayor ansiedad (72,7% vs 21,4%; p = 0,007). No se hallaron diferencias en su manejo clínico. CONCLUSIONES: La detección de MANF debería considerarse un dato de sospecha de consumo de catinonas sintéticas, y en esos casos debería contemplarse la detección de nuevas sustancias psicoactivas de abuso.

RESUMO

In December 2019, 27 cases of pneumonia were reported in Wuhan. In 2020, the causative agent was identified as a virus called SARS-CoV-2. The disease was called "coronavirus disease 2019" (COVID-19) and was determined as a Public Health Emergency. The main measures taken to cope with this included a state of lockdown. The aim of this study was to assess how the unhealthy lifestyles that ensued influenced different parameters. A prospective study was carried out on 6236 workers in a Spanish population between March 2019 and March 2021. Anthropometric, clinical, and analytical measurements were performed, revealing differences in the mean values of anthropometric and clinical parameters before and after lockdown due to the pandemic, namely increased body weight (41.1 ± 9.9-43.1 ± 9.9), BMI (25.1 ± 4.7-25.9 ± 4.7), and percentage of body fat (24.5 ± 9.1-26.9 ± 8.8); higher total cholesterol levels, with a statistically significant increase in LDL levels and a reduction in HDL; and worse glucose levels (90.5 ± 16.4-95.4 ± 15.8). Lockdown can be concluded to have had a negative effect on health parameters in both sexes in all age ranges, causing a worsening of cardiovascular risk factors.

RESUMO

INTRODUCTION: Vitamin D has known effects on the immune system, and its deficiency has been associated with allergen sensitization. MATERIAL AND METHODS: A retrospective study was performed to evaluate the association between 25(OH)vitamin D (25(OH)D) and specific IgE for the most frequent allergens in our area in children and adolescents. All subjects under 15 years of age with a determination of Phadiatop® or Phadiatop Infant® and close serum 25(OH)D determination were included, from 2012 to 2019. From this sample, demographic and analytical variables were collected: specific IgE to Dermatophagoides pteronyssinus; dog and cat dander; grass, olive, and pellitory pollens; egg white; and cow milk; as well as complete blood count analysis and immunoglobulins. RESULTS: A total of 749 subjects were recruited. Clusters according to deficiency, insufficiency, or sufficiency of 25(OH)D showed an association with age, Phadiatop® , D. pteronyssinus, cat and dog dander specific IgE, and a higher frequency of positive allergen sensitization (P < .05). Logistic regression, compared with vitamin D levels of greater than 30 ng/mL after age adjustment, showed that deficient 25(OH)D was associated with D. pteronyssinus (OR 1.90; 95% CI, 1.25-2.90) and dog dander (OR, 2.10; 1.10-4.02); whereas insufficient 25(OH)D was associated with cat dander (OR, 2.46; 1.15-5.28) and also with D. pteronyssinus (OR, 1.55; 1.06-2.29) (P < .05). No associations were found between 25(OH) D levels and other analytical parameters. CONCLUSION: Vitamin D status is associated with sensitization to D. pteronyssinus, and cat and dog dander in children and adolescents, and also with a higher number of positive specific IgE.

RESUMO

BACKGROUND: Information on the characteristics of patients with nosocomial influenza and associated complications is scarce. This study compared epidemiological and clinical characteristics of patients admitted with hospital-acquired influenza (HAI) to those with community-acquired influenza (CAI) and analyzed risk factors associated with complications. METHODS: This retrospective, observational study included all adult patients with confirmed influenza virus infection admitted to Son Espases University Hospital during the influenza season in Spain (October to May) from 2012-2013 to 2015-2016. Symptom onset before admission was included as CAI, and 2 days after admission or within 48 hours after previous discharge were considered as HAI. RESULTS: Overall, 666 patients with laboratory-confirmed influenza were included; 590 (88.6%) and 76 (11.4%) had CAI and HAI, respectively. Baseline characteristics and vaccination rates were similar in both groups. Patients with HAI had significantly fewer symptoms, less radiological alterations, and earlier microbiological diagnosis than those with CAI. Eighty-five (14.4%) and 20 (27.6%) CAI and HAI patients, respectively, experienced at least one complication, including septic shock, admission to the intensive care unit, mechanical ventilation or evolution to death (any one, P = .003). Univariate and multivariate binary logistic regression was performed to assess independent risk factors associated with the occurrence of complications: nosocomial infection, diabetes, oseltamivir treatment, having received no vaccination, microbiological delay, dyspnea, and the state of confusion were the most important significant factors. CONCLUSIONS: Our study shows the need to implement microbiological diagnostic measures in the first 48 hours to reduce HAI frequency and associated complications.

RESUMO

Objetivo: Investigar si existen diferencias clínicas y toxicológicas en pacientes intoxicados por anfetamina (ANF) y metanfetamina (MANF) atendidos en servicios de urgencias. Método: Estudio observacional retrospectivo de intoxicaciones por ANF y MANF con confirmación analítica en Baleares (2013-2018). Se compararon variables clínicas, toxicológicas y de manejo clínico entre grupos. Resultados: 1) Se incluyeron 120 pacientes, 86 (71,7%) grupo ANF y 34 (28,3%) grupo MANF. 2) La confirmación de derivados anfetamínicos se realizó por cromatografía de gases-espectrometría de masas en 787 muestras de orina previamente positivas mediante un método de cribado cualitativo. Se confirmaron 154 (19,6%) muestras. De ellas, 34 fueron excluidas. 3) Se encontraron diferencias significativas entre ANF y MANF en: edad (32,3 vs 28,4 años); sexo (72,1 vs 94,1% hombres); nacionalidad española (64,0 vs 29,4%); en motivos de admisión: alteración de conducta (15,1 vs 0%) y palpitaciones (1,2 vs 20,6%); y en características clínicas: agitación (27,9 vs 8,8%). No hubo diferencias de manejo clínico. El 76,6% de casos fueron polintoxicaciones, más comunes en ANF (82,6 vs 61,8%). En estos casos se detectó principalmente cocaína (63,0%), cannabis (48,9%), MDMA (38,0%) y alcohol (35,9%). La mayor asociación del cannabis con el grupo de ANF fue estadísticamente significativa (45,3 vs 17,6%). La causa de los falsos positivos se identificó en el 78,7% de muestras, siendo el MDMA (71,2%) la principal. Conclusiones: Se observaron diferencias entre ANF y MANF en cuanto a variables demográficas y motivo de asistencia; no obstante en esta serie hubo un alto porcentaje de polintoxicaciones


Objective: To determine whether clinical and toxicologic findings differed between cases of amphetamine (AMP) and methamphetamine (mAMP) poisoning attended in 2 Balearic Island hospital emergency departments. Methods: Retrospective observational study of AMP and mAMP cases with laboratory confirmation between 2013 and 2018. We compared clinical and toxicologic variables as well as clinical management between groups. Results: 1) A total of 120 cases were found: 86 (71.7%) with AMP poisoning and 34 (28.3%) with mAMP poisoning. 2) Drug poisoning was confirmed by gas chromatography associated with mass spectrometry (GC–MS) in 787 urine samples found to be positive during screening. One hundred fifty-four (19.6%) were confirmed by GC–MS. Thirtyfour of them did not meet the inclusion criteria. 3) Significant differences between AMP and mAMP cases were found for age (32.3 vs 28.4 y, respectively); sex (72.1% vs 94.1% men); and Spanish nationality (64.0% vs 29.4%). Reasons for admission and clinical features also differed: the reasons were aberrant behavior (15.1% in the AMP group vs 0% in the mAMP group) and palpitations (1.2% vs 20.6%); agitation was observed in 27.9% and 8.8%, respectively. Clinical management was similar in the 2 groups. Multiple drug poisoning was detected in 76.6% patients and was more common in patients in the AMP group (82.6% vs 61.8%). The additional drugs in these cases were mainly cocaine (63.0%), cannabis (48.9%), 3,4-methylenedioxy-N-methamphetamine (MDMA) (38.0%), and alcohol (35.9%). Cannabis was detected in a significantly higher proportion in the AMP group (45.3%) than in the mAMP group (17.6%). False positives were found in 78.7% of the samples. The culprit drug was most often MDMA (71.2%). Conclusions: AMP poisonings were associated with age over 30 years, Spanish nationality, aberrant behavior, agitation, multiple drug findings, and the use of cannabis. Poisonings caused by mAMP abuse were associated with age under 30 years, non-Spanish nationality, palpitations, and single-drug use

RESUMO

El fitato o myo-inositol-1,2,3,4,5,6-hexakis dihidrogenofostato (InsP6) es un compuesto fosforado de origen natural que está presente en numerosos alimentos, principalmente en legumbres, cereales integrales y frutos secos. Los pacientes con enfermedad renal crónica (ERC) experimentan una mortalidad por enfermedad cardiovascular hasta 30veces mayor que la población en general. Las calcificaciones vasculares (CV) contribuyen directamente en la morbimortalidad general, y de forma especial en la ERC. Esta elevada mortalidad se debe, en parte, a la elevación en los niveles de fósforo en sangre. Por ello, el control de fósforo en la dieta es fundamental. El fósforo dietético puede clasificarse en función de su estructura en fósforo orgánico (origen vegetal y animal) e inorgánico (conservantes y aditivos). El fósforo de origen vegetal (legumbres y frutos secos), principalmente asociado a InsP6, es menos absorbible por el tracto gastrointestinal humano siendo la biodisponibilidad del fósforo procedente de estos alimentos muy baja. Datos recientes indican que la restricción impuesta de alimentos que contienen fosfatos vegetales puede comprometer el aporte adecuado de nutrientes que tienen un efecto beneficioso en la prevención de episodios cardiovasculares, como pueda ser la fibra o al propio InsP6 presente en frutos secos y legumbres. Estudios experimentales en animales y observacionales en humanos sugieren que el InsP6 puede prevenir la litiasis, las CV y proteger de la osteoporosis. En conclusión, creemos necesario realizar estudios prospectivos para elucidar los posibles beneficios y riesgos de una dieta rica en fitato (InP6) en la ERC o de su uso como fármaco intravenoso en pacientes en hemodiálisis (AU)


Phytate, or myo-inositol 1,2,3,4,5,6-hexakis dihydrogen phosphate (InsP6), is a naturally occurring phosphorus compound that is present in many foods, mainly legumes, whole grains and nuts. Patients with chronic kidney disease (CKD) have cardiovascular disease mortality up to 30times higher than the general population. Vascular calcifications (VCs) directly contribute to overall morbidity and mortality, especially in CKD. In part, this high mortality is due to elevated levels of phosphorus in the blood. Therefore, control of dietary phosphorus is essential. Dietary phosphorus can be classified according to its structure in organic phosphorus (plant and animal) and inorganic (preservatives and additives). Plant-phosphorus (legumes and nuts), mainly associated with InsP6, is less absorbable by the human gastrointestinal tract as the bioavailability of phosphorous from plant-derived foods is very low. Recent data indicate that restriction of foods containing plant phosphates may compromise the adequate supply of nutrients that have a beneficial effect in preventing cardiovascular events, such as InsP6 or fibre found in legumes and nuts. Experimental studies in animals and observational studies in humans suggest that InsP6 can prevent lithiasis and VCs and protect from osteoporosis. In conclusion, we need prospective studies to elucidate the potential benefits and risks of phytate (InsP6) through the diet and as an intravenous drug in patients on haemodialysis (AU)
