Global cross-cultural validation of a brief measure for identifying potential suicide risk in 42 countries.

OBJECTIVES: This study aimed to examine the psychometric properties of the P4 suicide screener in a multinational sample. The primary goal was to evaluate the reliability and validity of the scale and investigate its convergent validity by analyzing its correlation with depression, anxiety, and substance use. STUDY DESIGN: The study design is a cross-sectional self-report study conducted across 42 countries. METHODS: A cross-sectional, self-report study was conducted in 42 countries, with a total of 82,243 participants included in the final data set. RESULTS: The study provides an overview of suicide ideation rates across 42 countries and confirms the structural validity of the P4 screener. The findings indicated that sexual and gender minority individuals exhibited higher rates of suicidal ideation. The P4 screener showed adequate reliability, convergence, and discriminant validity, and a cutoff score of 1 is recommended to identify individuals at risk of suicidal behavior. CONCLUSIONS: The study supports the reliability and validity of the P4 suicide screener across 42 diverse countries, highlighting the importance of using a cross-cultural suicide risk assessment to standardize the identification of high-risk individuals and tailoring culturally sensitive suicide prevention strategies.

Removal of malachite green from water: Comparison of adsorption in a residue-derived AC versus photocatalytic oxidation with TiO2 and study of the adsorption-photocatalysis synergy.

The literature rarely compiles studies devoted to the removal of pollutants in aqueous media comparing adsorption and photocatalytic degradation, and does not pay enough attention to the analysis of combined adsorption-photocatalytic oxidation processes. In the present manuscript, the removal of malachite green (MG) from aqueous solutions has been investigated in three different sustainable scenarios: i) adsorption on activated carbon (AC) derived from a residue, luffa cylindrica, ii) photocatalytic oxidation under simulated solar light using titanium dioxide (TP) and iii) combined adsorption-photocatalytic oxidation using TP-AC (70/30 wt./wt.) under simulated solar light. The study has revealed that in the three scenarios and studied conditions, the total removal of this endocrine-disrupting dye from the solution takes place in the assayed time, 2 h, in some cases just in a few minutes. MG adsorption in the AC is a very fast and efficient removal method. MG photocatalytic oxidation with TP also occurs efficiently, although the oxidized MG is not totally mineralized. MG removal using the TP-AC composite under simulated solar light occurs only slightly faster to the MG adsorption in the AC, being adsorption the dominating MG removal mechanism for TP-AC. Thus, more than 90% of the removed MG with TP-AC under simulated solar light is adsorbed in this carbon-containing composite. The obtained results highlight the interest in adsorption, being the selection of the most suitable removal method dependent on several factors (i.e., the cost of the AC regeneration, for adsorption, or the toxicity of the intermediate oxidation species, for photooxidation). Paying attention to MG photooxidation with TiO2, comparison of two working photodegradation schemes shows that the direct photodegradation of MG from solution, avoiding any initial dark equilibrium period, is more efficient from a time perspective. The use of scavengers has proved that MG photodegradation occurs via an oxidation mechanism dominated by superoxide anion radicals.

Diabetes tipo 1 y Miastenia Gravis / Type-1 Diabetes and Myasthenia Gravis

Introducción: El desarrollo de la tolerancia inmunológica frente a los autoantígenos se denomina autotolerancia. La Diabetes Mellitus tipo 1A (1ADM) es un trastorno metabólico secundario a la destrucción autoinmune de las células beta pancreáticas e insulitis. La miastenia grave (MG) es una enfermedad autoinmune causada por el bloqueo postsináptico de la placa mioneural por AAcs contra los receptores de acetilcolina (ACRA) o contra moléculas de la membrana postsináptica. La asociación entre DM1A y MG se puede observar en el síndrome poliglandular tipo III, caracterizado por enfermedad autoinmune de la glándula tiroides asociada con otras entidades autoinmunes. Método: Reporte de Casos, cuatro pacientes entre 7-19 años, con asociación de MG y DM1A atendidos en el Hospital Garrahan. Conclusión: La Tiroiditis de Hashimoto y la Enfermedad Celíaca son las enfermedades autoinmunes relacionadas más frecuentemente con DM1A en nuestra población. La bibliografía describe la asociación de MG y Tiroiditis de Hashimoto y su coexistencia con DM1A se describe en el Síndrome Poliglandular III. En este trabajo presentamos 4 casos de DM1A asociado con MG fuera de dicho síndrome (AU)

Introduction: The development of immune tolerance to autoantibodies (AAbs) is referred to as self-tolerance. Type 1A Diabetes Mellitus (1ADM) is a metabolic disorder secondary to autoimmune destruction of pancreatic beta cells and insulitis. Myasthenia gravis (MG) is an autoimmune disease caused by postsynaptic blockade of the myoneural plate by AAbs against acetylcholine receptors (Acra) or against postsynaptic membrane molecules. The association between 1ADM and MG may be observed in polyglandular syndrome type III, characterized by autoimmune disease of the thyroid associated with other autoimmune conditions. Methods: Case report; four patients between 7-19 years old, with an association of MG and 1ADM seen at the Garrahan Hospital. Conclusion: Hashimoto's thyroiditis and celiac disease are autoimmune diseases most frequently related to 1ADM in our population. In the literature, the association of MG and Hashimoto's thyroiditis has been described and its coexistence with 1ADM is reported in polyglandular syndrome III. In this study we present 4 cases of 1ADM associated with MG unrelated to this syndrome. (AU)

Surface-Enriched Boron-Doped TiO2 Nanoparticles as Photocatalysts for Propene Oxidation.

A series of nanostructured boron-TiO2 photocatalysts (B-X-TiO2-T) were prepared by sol-gel synthesis using titanium tetraisopropoxide and boric acid. The effects of the synthesis variables, boric acid amount (X) and crystallization temperature (T), on structural and electronic properties and on the photocatalytic performance for propene oxidation, are studied. This reaction accounts for the remediation of pollution caused by volatile organic compounds, and it is carried out at low concentrations, a case in which efficient removal techniques are difficult and costly to implement. The presence of boric acid during the TiO2 synthesis hinders the development of rutile without affecting the textural properties. X-ray photoelectron spectroscopy analysis reveals the interstitial incorporation of boron into the surface lattice of the TiO2 nanostructure, while segregation of B2O3 occurs in samples with high boron loading, also confirmed by X-ray diffraction. The best-performing photocatalysts are those with the lowest boron loading. Their high activity, outperforming the equivalent sample without boron, can be attributed to a high anatase and surface hydroxyl group content and efficient photo-charge separation (photoelectrochemical characterization, PEC), which can explain the suppression of visible photoluminescence (PL). Crystallization at 450 °C renders the most active sample, likely due to the development of a pure anatase structure with a large surface boron enrichment. A shift in the wavelength-dependent activity profile (PEC data) and the lowest electron-hole recombination rate (PL data) are also observed for this sample.

Are there differences between ceftolozane/tazobactam and ceftazidime/avibactam in treating patients with complicated abdominal infections? Evidence from clinical trials.

Ceftolozane/tazobactam (C/T) and ceftazidime/avibactam (CZA) are new possibilities of antimicrobial treatment that combined a ß-lactam with a ß-lactamase inhibitor. The United States (US) and European regulatory agencies approved their clinical use in adults with complicated intra-abdominal infections. This study aims to know if one of the two antibiotics obtain better efficacy in adults with complicated intra-abdominal infections and by specific pathogens such as P. aeruginosa or E. coli. A search of all trials in MEDLINE, Scopus, and Web of Science comparing a C/T or CZA based antimicrobial regimen with other treatments in patients with intraabdominal infections until August 2021 was performed. To make indirect comparisons, we used a frequentist approach using the R package netmeta.The effects have been expressed through the relative risk (RR) with its confidence interval. Considering the clinical cure and failure rates between the different trial populations (mMITT, CE, ME) and the mortality at the end of the study, we have not found significant differences between CZA and C/T. In the case of Pseudomonas, the RR of treatment failure between these two antibiotics is 1 (95% CI 0.55-1.18). In the case of E. Coli, although it seems that CZA would have a worse result than C/T, differences did not reach statistical significance (RR1.06; 95% CI 0.9-1.14). In conclusion, we have not found statistically significant differences between ceftolozane-tazobactam and ceftazidime-avibactam in treating cIAI. In regards to E. Coli, our results do not reach significance, but it would be possible that C/T and meropenem had better results than CZA. Perhaps new trials would allow a better profile of the role in different types of patients or infections caused by specific microorganisms in the future.

COVID-19 y embolia pulmonar: una nueva entidad / Covid-19 and pulmonary embolism: a new entity

El SARS-CoV-2 es un virus emergente que se extendió por todo el mundo desde China a finales de 2019, generando en el individuo una respuesta inflamatoria sistémica con afectación severa de los principales órganos (pulmón, corazón, sistema nervioso central, etc.). A la enfermedad causada por el mismo, la denominamos COVID-19. Una de las complicaciones descritas en la literatura, más frecuentemente asociadas a la infección, es la enfermedad tromboembólica venosa (embolismo pulmonar y trombosis venosa profunda). Se cree que la causa es debida a la inflamación excesiva y un estado de hipercoagulabilidad, con activación plaquetaria, disfunción endotelial y estasis sanguínea, que favorece la adhesión plaquetaria y formación de trombos. Presentamos dos casos clínicos diagnosticados en nuestro centro durante el periodo de pandemia en los que se observó esta complicación (AU)

SARS-CoV-2 is an emerging virus spread over the world from China in late 2019, generating in the patient a systemic inflammatory response with severe involvement of the main organs (lung, heart, central nervous system, etc.). The disease produced by this virus is called COVID-19. Previous studies show that one of the most commonly associated complications with COVID-19 is venous thromboembolic disease (pulmonary embolism and deep vein thrombosis). The cause is thought to be due to excessive inflammation and hypercoagulability, with platelet activation, endothelial dysfunction and blood theses, which promotes platelet adhesion and thrombus formation. We present two clinical cases reported during the pandemic period in which this complication was reported (AU)

Opsoclonus-myoclonus-ataxia syndrome associated with central nervous system HIV-1 escape phenomenon. / Síndrome opsoclono-mioclono-ataxia asociado a fenómeno de escape viral por virus de la inmunodeficiencia humana en el sistema nervioso central.

INTRODUCTION: Opsoclonus-myoclonus-ataxia (OMA) syndrome is a rare neurological disorder characterized by involuntary conjugate saccadic eye movements, myoclonus, and ataxia. Few reports exist on patients with HIV and OMA. CASE REPORT: A 41-year-old man diagnosed with HIV-1 infection in 1997 coursed with multiple anti-retroviral schemes as a consequence of poor adherence. In 2008 he presented an HIV-1 viral load of 100,000 copies/mL and a CD4+ T cell count of 10 cells/mm3. In 2013 our patient arrived with an 11-month history of progressive opsoclonus and ataxia. He had undetectable plasma HIV-1 RNA load and CD4+ of 606 cells/mm3. No opportunistic infections were found. Cerebrospinal fluid analysis showed mildly elevated protein concentration and HIV-1 viral load of 534 copies/mL. Cerebrospinal fluid co-receptor tropism test showed selective CCR5 usage. A brain magnetic resonance imaging showed hippocampal atrophy and T2-weighted hyperintensities. Our patient exhibited a dramatic recovery and cerebrospinal fluid HIV clearance after adjustment of anti-retroviral treatment based on genotyping resistance and tropism analyses. CONCLUSIONS: In patients with HIV presenting cengral nervous system dysfunction without opportunistic infections, cerebro-spinal fluid and plasma HIV-1 viral load, resistance and tropism tests should be performed to assess a potential viral escape and to design the appropriate anti-retroviral therapy in an individual patient basis.

TITLE: Síndrome opsoclono-mioclono-ataxia asociado a fenómeno de escape viral por virus de la inmunodeficiencia humana en el sistema nervioso central.Introducción. El síndrome opsoclono-mioclono-ataxia (OMA) es un trastorno neurológico infrecuente caracterizado por movimientos oculares conjugados sacádicos involuntarios, mioclonías y ataxia. Existen pocos casos en la bibliografía de pacientes con virus de la inmunodeficiencia humana (VIH) y OMA. Caso clínico. Varón de 41 años y diagnóstico de infección por el VIH-1 desde 1997, que cursó con múltiples esquemas antirretrovirales debido a una pobre adhesión al tratamiento. En 2008 presentó una carga viral de 100.000 copias/mL y una cuenta linfocitaria CD4+ de 10 células/mm3. En 2013 sufrió un cuadro progresivo de 11 meses de evolución caracterizado por opsoclonía y ataxia. En ese momento, su carga viral era indetectable, y la cuenta de CD4+, de 606 células/mm3. Se descartaron infecciones oportunistas. El examen del líquido cefalorraquídeo demostró hiperproteinorraquia leve y una carga viral de 534 copias/mL. El examen del tropismo de correceptor en el líquido cefalorraquídeo demostró un uso selectivo de CCR5. La resonancia magnética cerebral objetivó atrofia hipocámpica e hiperintensidades en las secuencias ponderadas en T2. El paciente mostró una recuperación clínica franca y un aclaramiento de la carga viral en el líquido cefalorraquídeo tras el ajuste de antirretrovirales basado en la resistencia de genotipo y el análisis de tropismo. Conclusiones. En pacientes con infección por el VIH y disfunción del sistema nervioso central sin infecciones oportunistas, debería llevarse a cabo una determinación de la carga viral en el plasma y el líquido cefalorraquídeo para descartar un potencial fenómeno de escape viral, así como exámenes de resistencia y tropismo para diseñar el tratamiento antirretroviral adecuado.

Molybdenum Cofactor Deficiency: Mega Cisterna Magna in Two Consecutive Pregnancies and Review of the Literature.

The molybdenum cofactor deficiency is an autosomal recessive disease, characterized by rapidly progressive and severe neurological damage that mimics a hypoxic-ischemic encephalopathy due to the accumulation of toxic metabolites that cause rapid neurodegeneration after the delivery. It is eventually lethal, in a similar way to the rare isolated sulfite oxidase deficiency. This serious pathology usually causes death in the immediate neonatal period in the more severe variants. We report a case of two consecutive pregnancies with enlarged cisterna magna as the only prenatal pathological finding since 26 weeks of gestation (WG) and the subsequent death of the newborns in the first week after birth. After the second pregnancy, we reached the diagnosis of molybdenum cofactor deficiency due to MOCS1 gene mutation. According to the cases reported in the literature, this is the case with the earliest neuroimage prenatal findings.

Randomized clinical trial of intracorporeal versus extracorporeal anastomosis in laparoscopic right colectomy (IEA trial).

BACKGROUND: Several non-randomized and retrospective studies have suggested that intracorporeal anastomosis (IA) has advantages over extracorporeal anastomosis (EA) in laparoscopic right colectomy, but scientific evidence is lacking. The aim was to compare short-term outcomes and to define the possible benefits of IA compared with EA in elective laparoscopic right colectomy. METHODS: An RCT was conducted from May 2015 to June 2018. The primary endpoint was duration of hospital stay. Secondary endpoints were intraoperative technical events and postoperative clinical outcomes. RESULTS: A total of 140 patients were randomized. Duration of surgery was longer for procedures with an IA than in those with an EA (median 149 (range 95-215) versus 123 (60-240) min; P < 0·001). Wound length was shorter in the IA group (median 6·7 (4-9·5) versus 8·7 (5-13) cm; P < 0·001). Digestive function recovered earlier in patients with an IA (median 2·3 versus 3·3 days; P = 0·003) and the incidence of paralytic ileus was lower (13 versus 30 per cent; P = 0·022). Less postoperative analgesia was needed in the IA group (mean(s.d.) weighted analgesia requirement 39(24) versus 53(26); P = 0·001) and the pain score was also lower (P = 0·035). The postoperative decrease in haemoglobin level was smaller (mean(s.d.) 8·8(1·7) versus 17·1(1·7) mg/dl; P = 0·001) and there was less lower gastrointestinal bleeding (3 versus 14 per cent; P = 0·031) in the IA group. IA was associated with a significantly better rate of grade I and II complications (P = 0·016 and P = 0·037 respectively). The duration of hospital stay was slightly shorter in the IA group (median 5·7 (range 2-19) versus 6·6 (2-23) days; P = 0·194). CONCLUSION: Duration of hospital stay was similar, but IA was associated with less pain and fewer complications. Registration number: NCT02667860 ( http://www.clinicaltrials.gov).

ANTECEDENTES: Varios estudios no aleatorizados y retrospectivos sugieren que la anastomosis intracorpórea (intracorporeal anastomosis, IA) tiene ventajas sobre la anastomosis extracorpórea (extracorporeal anastomosis, EA) en la colectomía laparoscópica derecha, pero no hay suficientes evidencias científicas. El objetivo del estudio fue comparar los resultados a corto plazo y definir los posibles beneficios de la anastomosis intracorpórea versus extracorpórea en la colectomía derecha laparoscópica electiva. MÉTODOS: Se realizó un ensayo clínico prospectivo y aleatorizado de mayo de 2015 a junio de 2018. El criterio de valoración principal fue la duración de la estancia hospitalaria. Los criterios de valoración secundarios fueron los eventos técnicos intraoperatorios y los resultados clínicos postoperatorios. RESULTADOS: Se aleatorizaron 140 pacientes. El tiempo quirúrgico fue más largo para la IA que para la EA (149,49 ± 27,24 versus 123,35 ± 36,56 min; P = 0,001). La longitud de la herida fue más corta en la IA (6,65 ± 1,21 versus 8,72 ± 1,44 cm; P < 0,001). La función digestiva se recuperó antes en la IA que en la EA (2,3 versus 3,3 días, P = 0,003) y la incidencia de íleo paralítico fue menor (13% versus 30%, P = 0,022). Los requisitos de analgesia postoperatoria fueron menores con la IA (39 ± 24,3 versus 53 ± 26; P < 0,001) y la puntuación de dolor (EVA) también fue menor (P < 0,035). El descenso de la hemoglobina en el postoperatorio y la hemorragia gastrointestinal baja fueron menores en la IA que en la EA (-8,83 ± 1,7 versus -17,07 ± 1,7 mg/dl; P = 0,001) y (2,8% versus 14%; P = 0,031), respectivamente. La clasificación de Clavien-Dindo mostró que la IA se asoció con resultados significativamente mejores que la EA: grado I (10% versus 27% P = 0,016); grado II (18% versus 35%, P = 0,0369). La puntuación del índice de complicación integral (comprehensive complication index, CCI) fue menor en el grupo IA (5,33 ± 9,2 versus 11,15 ± 14,34; P = 0,006). La estancia hospitalaria fue más corta en el grupo de IA pero sin diferencia significativa (5,65 ± 3,75 versus 6,58 ± 4,63 días; P = 0,194). CONCLUSIÓN: La IA presenta ventajas clínicas sobre la EA en la colectomía derecha laparoscópica.

[Patient satisfaction in the Spanish National Health System]. / Satisfacción del paciente en el Sistema Nacional de Salud español.

BACKGROUND: Determine which key indicators of the Spanish National Health Service (NHS) influence patient satisfaction with the Spanish NHS and physicians (family doctors and specialists). METHOD: The mean for each indicator for each autonomous community, published by the Ministry of Health, Social Services and Equality, corresponding to the years 2005 to 2014, was related to patient satisfaction by means of multiple linear regression. RESULTS: Patient satisfaction with the NHS was ascertained at 57.32%, with general practitioners at 54.45% and specialist doctors at 55.11%. In the three types of satisfaction, the number of specialist doctors, hospital admissions and in-hospital mortality had a positive and significant influence, while the number of surgical interventions had a negative influence. The greater use of computerized tomography equipment and the hospital infection rate had a negative effect on satisfaction with the NHS and with specialist physicians, while the percentage of outpatient surgery had a positive effect. The average hospital stay shows a negative relationship with satisfaction with family doctors and specialists. CONCLUSIONS: Health policies should consider an increase in the number of medical specialists, favour ambulatory surgery, facilitate hospital treatment, monitor the effectiveness of surgical interventions, control hospital infections and moderate the prescription of drugs through the use of alternatives in order to increase patient satisfaction.

Intracorporeal versus extracorporeal anastomosis in right hemicolectomy assisted by laparoscopy: study protocol for a randomized controlled trial.

BACKGROUND: Colorectal cancer (CRC) is the third most frequent cancer diagnosed in men and the second in women. Laparoscopic surgery has been a technical revolution in colorectal surgery, facilitating a better recovery of patients with lower morbidity and better esthetic results, compared to traditional surgery via laparotomy, without compromising safety and long-term oncological results. PURPOSE: The trial is a randomized controlled trial indented to evaluate the two interventions with thorough measurements of the postoperative variables and complications to improve the evaluation of the surgical technique. The primary endpoint is to compare the hospital stay, which will be measured in days between both groups. The purpose of the study at secondary endpoints is to compare intraoperative and postoperative events between both groups in terms of operating time, anastomotic performance time, intraoperative complications, number of harvested lymph nodes, need for blood transfusion, length of the surgical wound, start and tolerance of oral intake, beginning of digestive functionality, postoperative pain, need for analgesic administration, surgical wound infection, paralytic ileus, anastomosis leakage or dehiscence, need for surgical reintervention, and hospital readmission within the first 30 days after surgery. METHODS: This trial is a prospective, randomized, single-blind, and single-center clinical trial comparing intracorporeal anastomosis versus extracorporeal anastomosis for right laparoscopic hemicolectomy. CONCLUSIONS: Nowadays, there are several retrospective trials comparing the benefits for extracorporeal anastomosis versus intracorporeal anastomosis in right colon cancer patients. Considering the impact for laparoscopic surgery, we think it is necessary to do a randomized trial comparing extracorporeal versus intracorporeal anastomosis modalities.

[Vascular dysfunction in obstructive sleep apnoea: Implication of microparticules]. / Atteinte vasculaire associée au syndrome d'apnées hypopnées obstructives du sommeil : rôle des microparticules.

Obstructive sleep apnea (OSA) is associated with increased cardiovascular diseases, including myocardial infarction and stroke and promotes cardiovascular risk factors including diabetes and hypertension. OSA has also been proposed to have a direct proatherogenic effects. Recent studies have investigated the role of microparticles (MPs) in the atherogenic process. MPs are small plasma membrane vesicles that can be released by a variety of vascular or blood cells and that contain membrane and cytosolic elements. Case-control studies have suggested that OSA is associated with an increase in circulating platelet-, endothelial- and leukocyte-derived MPs. MPs from OSA patients injected to mice have also been shown to induce vascular inflammation and endothelial dysfunction. In this article, we provide an overview of the main characteristics of MPs expressed in OSA and their potential role in the atherogenic process.

Fertilization and connectivity in the Garrucha Canyon (SE-Spain) implications for Marine Spatial Planning.

Marine Spatial Planning is usually based on benthic georeferenced information or GPS tracked human activities, whereas the pelagic ecosystem is often ignored because of scarce and limited surface information. However, the 3-D pelagic ecosystem plays a key role connecting all the other ecosystems by physical (currents) and biological (migration) processes. According to remote sensing the Garrucha Canyon is oligotrophic, but 3-D sampling reveals subsurface upwelling, and converts it into the richest area around the Cape of Gata. Vertical connectivity by means of zooplankton migration, measured at two sampling stations, is 40 and 220 times faster than microphytoplankton settling and vertical water velocities respectively. Thus coupled physical-biological connectivity models are necessary to estimate the ecosystem connection and the fate of carbon, but also other substances (e.g. radioactivity), that might accumulate throughout the food-web. This is especially important in the Garrucha Canyon and the Coastal Areas Management Programme Levante de Almería where natural heritage and extractive fishery are important for the local economy.

Multidrug-Resistant Outbreak-Associated Salmonella Strains in Irrigation Water from the Metropolitan Region, Chile.

Salmonella enterica (S. enterica) is the main cause of foodborne diseases in the Chilean population. With the aim of characterizing the presence of S. enterica in bodies of water, samples from 40 sources were obtained, including rivers and irrigation canals used by agricultural farms in the most populated regions of Chile. As result, 35 S. enterica isolates belonging to several serotypes were detected, with the highest frequency represented by Typhimurium and Enteritidis. All strains showed phenotypic antimicrobial resistance, and most of them were multiresistant to critically important antimicrobials. In addition, the pulse-field gel electrophoresis analysis using XbaI and BlnI endonucleases showed that seven Salmonella isolates belonging to serotypes Typhimurium, Enteritidis and Infantis had identical pulsotypes to outbreak-associated clinical isolates detected in the Chilean population, suggesting a public health risk of water pollution in this region. Among sampling sites, the higher detection rates were observed in rural than urban and peri-urban areas, suggesting that the animal husbandry might contribute for environmental dispersion of this pathogen. Future efforts should address the characterization of cause-and-effect relationship between water contamination and foodborne disease, including the implementation of surveillance programmes to tackle potential risks for both human and animal populations.
