Telemedicine technologies are successfully implemented and will be used in a global perspective to optimize and improve the quality of diagnostic radiology. On the basis of teleradiology, the concept of centralized radiological reporting has been implemented. The centralization of expertise within the Reference Center provides a complete solution to the issues of staff shortage, uninterrupted research, the maximum level of accessibility and quality of diagnostic radiology. At the same time, the quality and effectiveness of the independent performance of X-ray technicians using telemedicine technologies without the direct presence of a radiologist remain unexplored.The aim of the study. To evaluate the quality and reliability of remote interaction between primary health care X-ray technicians and radiologists of the Reference Center for diagnostic radiology.Materials and methods. The study includes data on the performance of the Reference Center and pilot Moscow city medical facilities providing primary health care (city clinics, n = 12) from January 01, 2019 to March 31, 2021. The number and structure of X-ray technician requests to doctors of the Reference Center for consultations during conducting examinations, as well as a proportion and structure of defects in the performance of X-ray technicians have been relatively studied; satisfaction assessment has been conducted. The following methods were used: analytical, sociological, statistical.Results and discussion. In the conditions of remote performance, the proportion of studies which require communication between X-ray technicians and radiologists is only 0.38 % on average. The share of requests for assistance is decreasing by 35.0 %, while a total number of radiological studies reporting remotely is increasing by 10.0 % monthly. Leading reasons for requests are organizational issues – 45.0 %, admission of an unscheduled patient – 26.0 %. Critical questions on the study methodology are only 11.0 %. Under the working conditions of the Reference Center, the need of X-ray technicians for a doctor’s assistance during the study performance has decreased (p < 0.0001), the pace of getting a consultation if it is required, increased significantly, and time delays have been completely eliminated (p < 0.0001). A satisfaction rate of X-ray technicians with their professional activities has increased (p < 0.0001). In the conditions of remote interaction, the number of technological defects during radiological studies significantly decreased (p < 0.05).Conclusions. A concept of the Reference Center for diagnostic radiology based on the systemic application of telemedicine technologies has been successfully implemented in practice and proven its positive impact on the quality and safety of the performance of primary health care X-ray technicians.

Justification and purpose of the study. The high social significance of diabetic retinopathy (DR), the complexity of early diagnosis and monitoring of the disease determine the urgency of developing a system for diagnosing diabetic changes in the fundus using artificial intelligence (AI) methods. The aim of the work is to build a demo prototype of a WEB service for recognizing signs of DR from fundus images using machine learning methods using the Python language and the Django framework.Materials and methods. The study used the Messidor dataset (1200 eyes), which is publicly available on the Internet and includes photos of healthy fundus (546 eyes) and fundus with pathology (654 eyes). With the help of the augmentation method, this set for the study is increased several times. The fundus image recognition system is based on the trained neural network ResNet50. The web service with a connected neural network model was developed on the Django framework.Results. The main result of the research is the development of a test prototype of a service for the diagnosis of diabetic fundus changes based on photos using machine learning tools, demonstrating the great potential of using AI to improve the effectiveness of decisions. The sensitivity of the neural network model during the diagnosis of DR, even on a small test sample and limited training time, was 85 %.Conclusion. The high efficiency and potential of AI methods in the construction of a system for automatic detection of fundus pathology in the framework of the developed in the Helmholtz National Medical Research Center of Eye Diseases automated medical decision-making system. In the future, this service can be used to improve the effectiveness of early diagnosis and monitoring of diabetic changes in the fundus in conditions of reduced availability of primary ophthalmological care in parts of the Russian Federation, including at the pre-medical stage.
Por “Emergencias y urgencias en Reumatología clínica”
Authors: Dubinsky Diana 
Published: February 2022

Estimado Editor: hasta hace algunos años, no muchos, se decía que la Reumatología no tenía emergencias. Como excepción, se mencionaba la pérdida visual súbita de la arteritis temporal e incluso se sostenía que se diagnosticaba y trataba por teléfono.
Actualmente, al priorizar en la formación del reumatólogo el abordaje clínico del paciente, se aprende a conocer las emergencias de cada enfermedad autoinmune, detectarlas y, más aún, anticipar su eventual presentación (“tenerlas en mente”) para optimizar su manejo rápido y adecuado.

El Síndrome Antifosfolípidos (SAF) describe un trastorno trombofílico autoinmune caracterizado por complicaciones obstétricas. La Anexina A5 (Anx A5) es una proteína que se estudia como un nuevo autoantígeno presente en el SAF, la presencia de autoanticuerpos frente a Anx A5 podría causar trombosis placentaria y pérdida del embarazo.
El objetivo de este estudio fue analizar los niveles de IgG e IgM anti-Anx A5 en mujeres con SAF primario obstétrico y su asociación con diferentes complicaciones en una población de la ciudad de Córdoba.
Se trabajó con muestras de pacientes puérperas que asistieron al Hospital Córdoba y al Hospital Materno Neonatal durante los años 2013-2017 con diagnóstico de SAF obstétrico y un grupo control formado por pacientes con embarazos normales.
En la mayoría de las pacientes estudiadas, los niveles de IgG e IgM anti-Anx A5 se encontraron por debajo del rango de referencia, se mostró un aumento estadísticamente significativo de los niveles de IgG en pacientes con SAF respecto al grupo control. Pero no existieron asociaciones específicas entre los niveles de anticuerpo y los tres tipos de manifestaciones clínicas presentes en los criterios de clasificación.
Estos hallazgos podrían sugerir una relación entre los anticuerpos anti-Anx A5 con el SAF obstétrico.

PurposeThe aim of the study was to analyse the value of 2 different diffusion-weighted imaging (DWI) techniques (echo-planar imaging [EPI] and on-echo-planar imaging [non-EPI]) in the diagnosis of cholesteatoma.Material and methodsOur material consisted of 32 subjects suspected of cholesteatoma, who underwent magnetic resonance imaging of the temporal bone using both EPI and non-EPI DWI. Two independent readers retrospectively analysed magnetic resonance images. Intra- and interobserver agreements as well sensitivity, specificity, and negative (NPV) and positive (PPV) predictive values of both DWI sequences were assessed.ResultsUsing non-EPI DWI all cholesteatomas were correctly diagnosed by both readers with no false negative nor inconclusive cases and with only one false positive result. Non-EPI DWI revealed high interobserver agreement (κ = 1) and high correlation with histopathological results <i>(r</i> = 0.895). EPI DWI misdiagnosed 27-31% of cholesteatomas (false negative results), showing also significantly low interobserver agreement (κ = 0.373) and low correlation with histopathological results (<i>r</i> = 0.328 for reader 1 and <i>r</i> = 0.267 for reader 2). Non-EPI DWI revealed very high sensitivity (100%), specificity (83.3%), NPV (100%), and PPV (96.3%) in comparison to EPI DWI, which showed lower sensitivity (69.2%), specificity (66.6-83.3%), NPV (33.3-38.4%), and PPV (90.0-94.7%).ConclusionsNon-EPI DWI with high sensitivity, specificity, and interobserver agreement is a very reliable technique in detecting middle ear cholesteatoma regardless of the pre- or postoperative state of the ear, and it should entirely replace EPI DWI in clinical practice.

Abstract. Aerosol indirect radiative forcing (IRF), which characterizes how aerosols alter cloud formation and properties, is very sensitive to the preindustrial (PI) aerosol burden. Dimethyl sulfide (DMS), emitted from the ocean, is a dominant natural precursor of non-sea-salt sulfate in the PI and pristine present-day (PD) atmospheres. Here we revisit the atmospheric oxidation chemistry of DMS, particularly under pristine conditions, and its impact on aerosol IRF. Based on previous laboratory studies, we expand the simplified DMS oxidation scheme used in the Community Atmospheric Model version 6 with chemistry (CAM6-chem) to capture the OH-addition pathway and the H-abstraction pathway and the associated isomerization branch. These additional oxidation channels of DMS produce several stable intermediate compounds, e.g., methanesulfonic acid (MSA) and hydroperoxymethyl thioformate (HPMTF), delay the formation of sulfate, and,
hence, alter the spatial distribution of sulfate aerosol and radiative
impacts. The expanded scheme improves the agreement between modeled and
observed concentrations of DMS, MSA, HPMTF, and sulfate over most marine
regions, based on the NASA Atmospheric Tomography (ATom), the Aerosol and
Cloud Experiments in the Eastern North Atlantic (ACE-ENA), and the
Variability of the American Monsoon Systems (VAMOS)
Ocean-Cloud-Atmosphere-Land Study Regional Experiment (VOCALS-REx)
measurements. We find that the global HPMTF burden and the burden of sulfate produced from DMS oxidation are relatively insensitive to the
assumed isomerization rate, but the burden of HPMTF is very sensitive to a
potential additional cloud loss. We find that global sulfate burden under PI and PD emissions increase to 412 Gg S (+29 %) and 582 Gg S (+8.8 %), respectively, compared to the standard simplified DMS oxidation scheme. The resulting annual mean global PD direct radiative effect of DMS-derived sulfate alone is −0.11 W m−2. The enhanced PI sulfate produced via the gas-phase chemistry updates alone dampens the aerosol IRF as anticipated (−2.2 W m−2 in standard versus −1.7 W m−2, with updated gas-phase chemistry). However, high clouds in the tropics and low clouds in the Southern Ocean appear particularly sensitive to the additional aqueous-phase pathways, counteracting this change (−2.3 W m−2). This study confirms
the sensitivity of aerosol IRF to the PI aerosol loading and the
need to better understand the processes controlling aerosol formation in the PI atmosphere and the cloud response to these changes.

Background: Lumbosacral spinal stenosis (LSS) is one of the most common causes of back pain and disability. Its treatment varies from conservative and medical to surgical treatment, and the indications for its optimal management are not obviously defined. Epidural steroid injection is commonly used for pain relief in LSS. This study aims to compare the adjuvant efficacy of caudal epidural injection (CEI) of hyaluronidase with steroid versus hypertonic saline with steroid in patients with LSS. Methods: This clinical trial was done in a prospective, randomized, double-blind approach; it was conducted among 30 patients aged between 45 – 75 years who suffered from low back and leg pain in recent 6 months due to LSS. The patients were randomly allocated to two groups. Group A included 15 patients who received fluoroscopically guided CEI containing steroid, local anesthetic, and hyaluronidase, and Group B consisted of 15 patients who received fluoroscopically guided CEI containing steroid, local anesthetic, and hypertonic saline. The outcome measures included the Visual Analog Scale (VAS), Oswestry Disability Index (ODI), and Quebec Back Pain Disability Scale (QBPDS), which were obtained from patients before the CEI as a baseline and after the second, fourth, and eighth weeks. Results: Before injection, there were no statistically significant differences between the two studied groups, neither in demographic characteristics nor in VAS, ODI, and QBPDS parameters. After injection, the mean of ODI and QBPDS improved from the baseline to the 2nd, 4th, and the 8th weeks in both groups (p < 0.001) without any superiority between the two groups (p > 0.05). However, there was a significant improvement of the mean VAS score through the second and fourth weeks in Group A (p = 0.032, 0.050). VAS score in the eighth week was equal without any superiority in both groups (p > 0.05). Additionally, the mean social life status was significantly improved in group A in the 4th and 8th weeks after the intervention. Conclusions: In short-term follow-up, Caudal epidural injection of hyaluronidase, as well as hypertonic saline, seems to be effective in the management of LSS without any superiority in both materials. However, in the 2nd and 4th weeks after the procedure, better improvement of means VAS score was observed in the hyaluronidase group.

This study focuses on the cultural revitalization aspect as an urgent matter in the Indonesia-Malaysia border region, SajinganBesar Sub-district, Sambas Regency. The results of this study can be summarized that the main problem of cultural development in the border region is not only caused by globalization but also concerns on the condition of cultural resilience of the border communities themselves who have experienced stagnation which is from the conditions that are completely and inevitably marginal of Globalization, then it must be anticipated with cultural development that is characterized by the reinforcement of identity and local wisdom of the border community which is used as the basis for arranging strategies in preserving and developing culture. This study used a qualitative approach that was carried out by survey data, observation, analysis and FGD (Forum Group Discussion). This method is very effective for something that is urgent and important and will provide an increase in the welfare of the community whose life is generally less prosperous. Moreover, geopolitically, the cultural revitalization will further ensure the realization of the revitalization policy of the culture of the Indonesian Archipelago in the border region which can create nationalism, and maintain the border region from foreign infiltration as well as become a space for conflict resolution to create peace between countries.
