Trace gases detection by photoacoustic technique based on a lineal chirp excitation scheme

En este trabajo se presenta un nuevo esquema de medición para espectroscopía fotoacústica de gases traza basado en un esquema de excitación up-chirp. Esta forma combina las ventajas de los esquemas resonante y pulsado. Para mostrar el potencial de esta técnica se la comparó con un esquema de excitación resonante sobre la medición de muestras de dióxido de nitrógeno en aire contenidas en una resonador acústico de alumnio. Los resultados mostraron que la técnica chirp permite realizar mediciones de corta duración con muy buena relación señal a ruido.We present a new photoacoustic gas-trace measurement setup, based on a chirped optical chopper. This method combines features of the resonant and pulsed techniques. To show the advantages of this setup, we carried out a comparison with the resonant method in samples of NO2 contained in a one-dimensional acoustic resonator. The results show the chirped technique allows carrying out short-term acquisitions with good signal-to-noise ratio.Fil: Carreño Romano, Carlos Germán. Universidad de Buenos Aires.

Pseudopterygium : An Algorithm Approach Based on the Current Evidence

Publisher Copyright: © 2022 by the authors.Pseudopterygium is a non-progressive conjunctival adhesion to the peripheral cornea secondary to a corneal-limbus damage. According to the literature, the main etiology is a previous eye trauma. Nevertheless, this could be biased by the existence of other underdiagnosed causes of pseudopterygium, some of which may have severe consequences for the integrity of the eye and patient’s life. This comprehensive literature review was performed based on a search on the PubMed and Google Scholar databases of relevant pseudopterygium published papers according to our current knowledge and seeks to gather the existing evidence about its diverse etiologies and clinical features, as well as to propose a diagnostic algorithm to simplify its correct approach.publishersversionPeer reviewe

Intraperitoneal drain placement and outcomes after elective colorectal surgery: international matched, prospective, cohort study

Despite current guidelines, intraperitoneal drain placement after elective colorectal surgery remains widespread. Drains were not associated with earlier detection of intraperitoneal collections, but were associated with prolonged hospital stay and increased risk of surgical-site infections.Background Many surgeons routinely place intraperitoneal drains after elective colorectal surgery. However, enhanced recovery after surgery guidelines recommend against their routine use owing to a lack of clear clinical benefit. This study aimed to describe international variation in intraperitoneal drain placement and the safety of this practice. Methods COMPASS (COMPlicAted intra-abdominal collectionS after colorectal Surgery) was a prospective, international, cohort study which enrolled consecutive adults undergoing elective colorectal surgery (February to March 2020). The primary outcome was the rate of intraperitoneal drain placement. Secondary outcomes included: rate and time to diagnosis of postoperative intraperitoneal collections; rate of surgical site infections (SSIs); time to discharge; and 30-day major postoperative complications (Clavien-Dindo grade at least III). After propensity score matching, multivariable logistic regression and Cox proportional hazards regression were used to estimate the independent association of the secondary outcomes with drain placement. Results Overall, 1805 patients from 22 countries were included (798 women, 44.2 per cent; median age 67.0 years). The drain insertion rate was 51.9 per cent (937 patients). After matching, drains were not associated with reduced rates (odds ratio (OR) 1.33, 95 per cent c.i. 0.79 to 2.23; P = 0.287) or earlier detection (hazard ratio (HR) 0.87, 0.33 to 2.31; P = 0.780) of collections. Although not associated with worse major postoperative complications (OR 1.09, 0.68 to 1.75; P = 0.709), drains were associated with delayed hospital discharge (HR 0.58, 0.52 to 0.66; P < 0.001) and an increased risk of SSIs (OR 2.47, 1.50 to 4.05; P < 0.001). Conclusion Intraperitoneal drain placement after elective colorectal surgery is not associated with earlier detection of postoperative collections, but prolongs hospital stay and increases SSI risk

Las consecuencias del estigma en familiares de pacientes: un estudio en establecimientos, servicios y programas de salud mental

La Colonia Nacional Montes de Oca es una institución neuropsiquiátrica dependiente del Ministerio de Salud de la Nación en la que se ha desarrollado un programa que comprende la externación y alojamiento de pacientes en Centros de Atención, como hogares y residencias comunitarias. Tales instituciones promueven la convivencia de un pequeño número de pacientes, brindan asistencia integral a cargo de un equipo interdisciplinario de salud y aseguran los servicios de apoyo necesarios para la rehabilitación e integración social. Los objetivos de la investigación fueron: a) caracterizar los procesos de externación asistida destinados a pacientes institucionalizados bajo modalidad de internación crónica; b) indagar diferenciass en la calidad de vida de los usuarios de dispositivos residenciales comunitarios respecto de pacientes alojados en servicios de internación crónica; c) evaluar el prejuicio hacia pacientes atendidos bajo las distintas modalidades asistenciales. El diseño metodológico, transversal y descriptivo, comprendió el empleo de instrumentos de relevamiento adaptados (instrumento GENCAT para evaluación de la calidad de vida) y elaborados por el equipo técnico (guías de relevamiento). Abarcaron a todos los centros residenciales de base comunitaria, según las siguientes variables: a) perfil de usuarios; b) cobertura de Atención; c) modalidad de tratamiento; d) utilización de servicios sociales y sanitarios; e) egresos y retornos a la Institución; e) principales barreras u obstáculos identificados. Se efectuó seguidamente la evaluación de pacientes atendidos en tales dispositivos de base comunitaria y su comparación con aquellos que continuaron recibiendo atención en servicios de internación crónica. Para tal fin, se especificaron las variables de corte para el análisis de los resultados, los cuales arrojaron las siguientes conclusiones: los dispositivos comunitarios exhiben indicadores favorables de gestión administrativa que se expresan en una reducción de los costos por paciente y un menor ausentismo registrado del personal asistencial; se observan mejor desempeño de los indicadores vinculados a la percepción de una mejor calidad de vida en los pacientes tratados bajo la modalidad de externación asistida en dispositivos residenciales comunitarios; las actitudes y conductas discriminatorias hacia los pacientes se incrementan en quienes acreditan más tiempo de internación en la Colonia y expresan mayores niveles de discapacidad funcional.Colonia Montes de Oca National is a neuropsychiatric establishment controlled by the Ministry of Health of the Nation in which it has been developed a program that includes the going out of the main institution and the accommodation of this patients in care centers such as homes and community residences. Such institutions promote the coexistence of a small number of patients, provide complete assistance by an interdisciplinary team of health and assure the necessary support services for rehabilitation and social integration. The objectives of the research were: a) To characterize the process of going out of the institution applied to chronic patients; b) To investigate the differences in quality of life between patients of residential communities and chronic patients; c) To evaluate the prejudice toward patients treated under both modalities. The research design, transversal and descriptive, was carried out by instruments of survey like GENCAT (evaluates the quality of life) and created by the technical team. This was applied to all the residential communities, characterized by the following variables: a) Users profile; b) Care Coverage; c) Outpatient or inpatient modality; d) Use of social and health services; e) Exits and returns to the institution; e) Main obstacles identified. Then, the patients that are in this community centers were evaluated comparing them with the ones who continued like chronic patients. For this purpose, they settled the cut variables for the results analysis, which threw the following conclusions: a) The community devices show a favorable indications of administrative management which are expressed in the reduction of cost per patient and a minor absenteeism registered of the assistance staff; b) A better performance of the indicators linked to the perception of a higher quality of life in patients treated under the modalityof outside-institution in residential communities; c) The attitudes and discriminatory behaviours towards patients increases in people that have more time in the institution and they have higherlevels of functional disability

Next-Generation Sequencing on Circulating Tumor DNA in Advanced Solid Cancer: Swiss Army Knife for the Molecular Tumor Board? A Review of the Literature Focused on FDA Approved Test

FDA-approved next-generation sequencing assays based on cell-free DNA offers new opportunities in a molecular-tumor-board context thanks to the noninvasiveness of liquid biopsy, the diversity of analyzed parameters and the short turnaround time. It gives the opportunity to study the heterogeneity of the tumor, to elucidate complex resistance mechanisms and to adapt treatment strategies. However, lowering the limit of detection and increasing the panels’ size raise new questions in terms of detection of incidental germline alterations, occult malignancies and clonal hematopoiesis of indeterminate potential mutations. In this review, after a technological discussion and description of the common problematics encountered, we establish recommendations in properly using these FDA-approved tests in a molecular-tumor-board context
