Key considerations: Outbreak of Marburg virus disease in Rwanda, October 2024
Authors: Lamarque Hugh
Published: October 2024

This brief summarises key considerations regarding the outbreak of Marburg virus disease (MVD) in Rwanda, including national response capabilities, local governance structures and regional and economic implications. It is based on a rapid review of existing published and grey literature, news reports, previous research in Rwanda and informal conversations with national and international colleagues, and those involved in the response. The outbreak was officially declared on 27 September 2024, and is the first occurrence of MVD in Rwanda. At the time of writing (14 October 2024), there have been 62 reported: 15 people have died, 21 people are in isolation and receiving treatment, and 26 people are reported to have recovered. Most confirmed cases have been healthcare workers. Confirmed cases have been reported in seven of Rwanda’s 30 districts: Gasabo, Gatsibo, Kamonyi, Kicukiro, Nyagatare, Nyarugenge and Rubavu. The presence of the disease in multiple districts raises serious concerns about intercommunal spread. Testing efforts have expanded, with the Ministry of Health reporting that over 3,797 tests had been conducted as of 14 October 2024.

Authors: Anato Lognidé Serge Eunock , Ahehehinnou Mahugnon Armelle , Dako Sidoine Aude Sèdami , Anato Judivie Calgène
Published: October 2024

Contexte : Face au besoin croissant en aliments sains et nutritifs d’une part non négligeable de la population au Bénin, le développement de la chaîne de valeur des oeufs de caille devient une sérieuse option pour couvrir la demande en oeufs. Objectif : Cette étude visait à analyser l’efficacité technique des producteurs d’oeufs de caille, la rentabilité économique de cette production et la relation entre ces deux paramètres. Méthodes : Les données utilisées ont été obtenues par une enquête réalisée auprès d’un échantillon de 37 producteurs d’oeufs de caille du département de l’Atlantique. Les scores d’efficacité technique ont été estimés grâce à une fonction frontière de production stochastique de type Cobb-Douglas. L’analyse de la rentabilité a été réalisée en adoptant la méthode des marges. Résultats : Le score moyen d’efficacité technique obtenu est de 71,8 % et varie de 18,2 % à 97,4 %. Si les producteurs étudiés sont en majorité techniquement performants, il existe toutefois d’importants écarts que certains pourraient combler en apprenant à mieux allouer les ressources productives. En outre, les charges réelles de production s’élèvent à 2 722 FCFA par caille et représentent 73,6 % des charges globales de production. Avec une marge brute de 3 900,5 FCFA par caille, une marge nette de 2 567 FCFA par caille, un revenu agricole de 3 543 FCFA par caille en six mois et un taux de rentabilité financier de 78,0 %, la production d’oeufs de caille est rentable. Ces quatre indicateurs sont positivement corrélés aux niveaux de performance technique. Conclusion : Il existe de réelles opportunités d’augmentation des gains des producteurs techniquement faibles à travers l’amélioration de leur performance technique grâce à des formations sur les bonnes pratiques de production.

Authors:   , Schwartz Ivonne
Published: October 2024

The goal of this cumulative dissertation is two-folded. The first two chapters are dedicated to foster the research on agent-based financial market models by studying two newly developed models that aim at explaining a broad number of stylized facts of financial markets. Chapters 2 and 3 seek to answer how behavioral patterns of speculators may help to explain complex phenomena of financial markets. The second aim of this thesis is to deepen the understanding of estimation and validation approaches when applied to agent-based financial market models. With the rise of computational power, simulation-based methods have become a popular choice. Chapters 4 and 5 of this thesis are going to shed light on the potential difficulties when applying simulated moment estimators to validate agent-based financial market models.

Authors: Смілянець Ф.
Published: October 2024

У даному дослідженні розглянуто можливість побудови розширюваного методу класифікації зображень із використанням згорткової нейронної мережі генерації вкладених представлень для подальшого використання з простішими алгоритмами машинного навчання. Можливість використання цього підходу для додавання нових класів шляхом додаткового навчання без зміни топології мережі векторизації була продемонстрована на двох наборах даних: MNIST та Fashion-MNIST. Для цього було навчено звичайну класифікаційну згорткову нейронну мережу на обох наборах даних з використанням перших трьох класів. Відповідні натреновані мережі були модифіковані для генерації вкладених представлень. Додаткові шари для генерації ембеддингів в обох мережах були натреновані з використанням триплетної функції втрат з метою видобування ознак з виходу згорткових шарів, при цьому зберігаючи розрізнення між класами. Декілька простіших алгоритмів машинного навчання були натреновані для класифікації на основі отриманих вкладених представлень. Для перевірки гіпотези розширюваності, до навчальних наборів мереж було додано четвертий клас, мережі дотреновано та інші алгоритми навчено з нуля. Було виміряно точність класифікації на основі вкладених представлень мереж з 3 та 4 класами. Додатково було проведено аналіз витрат часу для звичайних класифікаційних мереж і запропонованого методу. Результати дослідження свідчать про те, що цей підхід може зменшити час і складність повторного навчання, особливо для більш складних завдань класифікації зображень, а також пропонує додаткові можливості, такі як пошук схожості у векторних базах даних. Однак для простіших завдань звичайні класифікаційні мережі залишаються більш ефективними з точки зору часу.

Published: October 2024

The Ultra-Cold Neutron (UCN) source being commissioned at North Carolina State Universityâs PULSTAR reactor is uniquely optimized for UCN production in the former graphite-filled thermal column outside of the reactor pool. The source utilizes a remote moderation design which is particularly well suited to the PULSTAR reactor on account of its large thermal and epithermal neutron leakage from the core face. This large non-equilibrium flux from the core is efficiently transported to the UCN source through the specially designed beam port in order to optimize UCN production at any given reactor power. The increased distance to the source from the core also greatly limits the heat load on the cryogenic system. A MCNP model of this system was developed and is in good agreement with gold foil activation measurements using a mock-up setup as well as with the real UCN source heavy water moderator. These results established a firm baseline for estimates of the cold neutron flux available for UCN production and prove that remote moderation in a thermal column port is a valuable option for future designs of cryogenic UCN sources.
On the Salient Regularities of Strings of Assembly Theory
Authors: Bieniawski Wawrzyniec , Masierak Piotr , Tomski Andrzej , Łukaszyk Szymon
Published: October 2024

Using assembly theory of strings of any natural radix b we find some of their salient regularities. In particular, we show that the upper bound of the assembly index depends on the radix b both quantitatively and qualitatively, and the longest length N of a string that has the assembly index of N-k is given by N(N-k)=b2+b+3k-2 for k={1,2,3,4}. We also provide particular forms of such strings. For k=1 such odd length strings are nearly balanced and there are four such different strings if b=2 and seventy-two if b=3. The assembly depth of a string has a value between the minimum assembly index for the length of this string and the assembly index of this string. Since these results are valid also for b=1, assembly theory subsumes information theory.
Predicting Marshall Stability and Flow Parameters in Asphalt Pavements Using Explainable Machine-Learning Models
Authors: Asi Ibrahim , Alhadid Yusra , Alhadidi Taqwa
Published: October 2024

The traditional method for determining the Marshall stability (MS) and Marshall flow (MF) of asphalt pavements is laborious, time consuming, and costly. This study aims to predict these parameters using explainable machine-learning techniques. A comprehensive database comprising 721 hot mix asphalt (HMA) data points was established, including variables such as aggregate percentage, asphalt content, and specific gravity. Models were constructed using the PyCaret Python library, and their performance was assessed using metrics such as the mean absolute error (MAE) and coefficient of determination (R²). The CatBoost regression model outperformed the other models, achieving R² values of 0.835 and 0.845 for MS and MF, respectively. Additionally, Shapley values were used to quantify the variable effects on the predictions. This approach enables the efficient preselection of design variables, reducing the need for extensive laboratory testing and promoting sustainable construction practices.

Authors: Leng Yuchen , Sanjon Cedric Wilfried , Tan Qingxiang , Groche Peter , Hauptmann Marek , Majschak Jens-Peter
Published: October 2024

The evaluation of wrinkles in deep-drawn fiber-based materials is crucial for the assessment of product quality and the optimization of manufacturing processes. Wrinkles, a common phenomenon in deep-drawing paper materials with high drawing depths, significantly impair the appearance and mechanical properties of the final product. The objective of this study is to identify the key process parameters affecting wrinkling and to deepen the understanding of their roles and interactions using wrinkle data for deep-drawn paper products. Image analysis techniques are employed, supported by a specially constructed darkroom platform to ensure uniform light intensity for capturing photographs. An automated program is developed for the detection and evaluation of wrinkle characteristics and distribution, which allows the free choice of the region to be detected and the representation of the wrinkle geometry not limited by the number. To enhance the precision of this program, the ellipticity is initially rectified for products without flanges, specifically cup-shaped deep-drawn products. The ellipticity is caused by the pronounced springback effect of the paperboard. The approach is employed to investigate the impact of material properties, blank holder force, drawing depth, drawing clearance, and punch speed on wrinkling formation after the deep drawing process. The findings reveal that the blank holder force and drawing clearance are critical factors in wrinkle formation, with higher forces generally leading to increased wrinkle numbers.
Genetic Mechanisms of Natural Short Sleep: A Review of DEC2, ADRB1, NPSR1, GRM1 Mutations and Recommended Testing for Chronic Health Implications
Authors: Gu Helene
Published: October 2024

Sleep deprivation is an increasing problem in the modern age. While molecular theories on the mechanism of sleep are still developing, sleep’s importance for cognitive function and physical health has been well reported. In the past 2 decades, major advances in the genetics of sleep have been made. Among families of natural short sleepers averaging around 4-6 hours nightly, mutations on 4 genes (DEC2, ADRB1, NPSR1, and GRM1) have been associated with significantly shorter sleep without observed cognitive or health detriments. Studies in mice have further established causality of these mutations as well as finding increased resistance to neurodegeneration. Yet, despite these promising results, there is a current lack of studies investigating potential chronic risks of sleep deprivation, particularly physical and physiological effects that may not be apparent. For circadian repressor element DEC2, circadian dysregulation risks should be evaluated further. For adrenergic receptor ADRB1, cardiovascular and heart failure risks would be of interest. For NPSR1, asthma and other immune responses, as well as mood disorders are relevant. For the currently least studied G-protein receptor GRM1, its altered regulation of the extracellular signal-regulated kinase (ERK) pathway could result in developmental and proliferation effects. While these familial natural short sleep genes hold potential for our understanding of sleep and therapeutic development, it is critical not to overdraw conclusions. By investigating the possible downstream effects, one can be aware of the potential risks of natural short-sleep genetics, better understand the mechanisms of sleep, and advance research in reducing the harms of sleep deprivation.
Effect of Cryogenic Treatment Applied to Cutting Tool on Machining Parameters and RSM Optimization
Authors: Kara Fuat , Takmaz Aysun
Published: October 2024

This study deals with the turning of AISI O2 steel, which has high machinability and dimensional stability in heat treatment and is used in the manufacture of many machine elements, with cryogenically treated and untreated and coated and uncoated cutting tools. In the first phase of the study, along with the determined cutting parameters, Fc and Ra output parameters were also optimized using the RSM method. In addition, numerical significance was obtained with ANOVA analysis, and estimated values were calculated by preparing regression equations. In the second phase, the wear performance of cutting tool tips with and without deep cryogenic treatment was explained with the support of SEM images, EDX, XRD, and microhardness analyses. Feed (F) was found to be the most influential parameter on Fc at 78.89%. The lowest optimized Fc value found with the RSM method was 339.99 N. In order to obtain this value, Vc 252.525 m/min and F 0.16 mm/rev should be selected. In addition, CVD-coated and cryogenic heat-treated cutting tools should be preferred for ideal Fc. It was shown that the most effective parameter on Ra was F, with 69.38%. For both heat treatment and coating conditions, Ra increased significantly as the feed rate increased. In the case of selecting Vc as 243.434 m/min and F as 0.16 mm/rev, the smallest Ra value optimized with the RSM method is 1.04 μm. In addition, a cutting tool without coating and cryogenic heat treatment is also needed for ideal Ra. According to the results of the analysis confirming the effect of deep cryogenic heat treatment on the wear performance of cutting tools in the second stage, coated and uncoated cutting tools had at least 16% longer life compared to the others.

Published: October 2024

Cutaneous metastases from clear cell renal carcinoma (ccRC) are uncommon and often indicate a poor prognosis. These metastases typically occur on the scalp, face, and trunk, and they can be difficult to diagnose due to their resemblance to benign dermatological tumors. We report the case of a 56-year-old patient with a history of ccRC (TNM stage 4) who was referred to our Dermatology department with two rapidly enlarging, painful lesions on the left jawline and scalp, which had developed one month and one week earlier, respectively. On examination, the lesions appeared as well-defined, round to oval plaques with a central ulceration and a peripheral red rim. Dermoscopic examination revealed a structureless pink to orange pattern, atypical central vessels, and irregular linear vessels in a corona-like arrangement. Despite the patient's stable oncological treatment for six months, pain management had recently included paracetamol, tramadol, and NSAIDs. Given the recent medication changes and the clinical presentation, differential diagnoses initially included drug-induced eruptions such as erythema multiforme or fixed drug eruption. However, a biopsy of the facial lesion revealed immunohistochemical positivity for CD10, CAIX, and PAX8, confirming the diagnosis of metastatic ccRC with sarcomatoid differentiation. Unfortunately, despite continued targeted therapies and palliative care, the patient’s condition deteriorated rapidly, leading to death two months later. This case highlights the aggressive progression and poor prognosis associated with cutaneous metastases from renal cell carcinoma, particularly once the skin is involved.

Polo-Like Kinase-1 (PLK1) is a key regulator of the G2/M cell cycle and has been linked to treatment resistance in prostate cancer (PCa). This study aimed to explore the correlation between PLK1 expression, determined through RNA-seq analysis, and clinical outcomes in PCa patients. We analyzed tumor samples from 452 patients diagnosed with prostate adenocarcinoma between 2014 and 2020, sourced from nine institutions affiliated with the Oncology Research Information Exchange Network (ORIEN). PLK1 expression levels were determined using RNA-seq data and stratified into high (≥75th percentile) vs. low (<75th percentile) expression. Univariate and multivariate Cox proportional hazard models compared overall survival between patients with low vs. high PLK1 expression, adjusting for age, race, PSA, and stage. Of the 452 tumors, 241 (53.3%) had high PLK1 and 211 (46.7%) had low PLK1 expression. Median follow-up was 2.74 years for low PLK1 and 2.71 years for high PLK1. No significant difference in overall survival was observed between low and high PLK1 groups in univariate (p=0.86; HR 1.09) or multivariate (p=1.0; HR 0.99) analyses. This study found no association between RNA-seq-based PLK1 expression and prognosis in PCa. PLK1 expression is not a prognostic marker for prostate cancer.
Thermoregulation and Soil Moisture Management in Strawberry Cultivation Mulched with Sheep Wool
Authors: Broda Jan , Gawlowski Andrzej , Rom Monika , Kukulski Tomasz , Kobiela-Mendrek Katarzyna
Published: October 2024

The application of wool as mulch in strawberry cultivation was analysed to find a so-lution for the rational use of wool from mountain sheep. In the plantation, the experimental plots mulched with wool, straw and bark were appointed. The plots were monitored during the ex-periment, while the soil temperature and moisture content were measured. The data collected in two-hour intervals were analysed, taking into account air temperature and falls registered in the local meteorological station. Additionally, the progress of mulch biodegradation was tracked. The changes in the wool morphology that occurred by biodegradation were observed during micro-scopic examinations using the Scanning Electron Microscope (SEM). It was stated that wool mulch plays an essential role in thermoregulation of the soil surface, prevents the overheating of the soil during the summer heat and protects it against excessive cooling during cold nights. The wool mulch minimises the fluctuations between the soil’s day and night temperature. The fluctuations do not exceed 2 - 3 degrees on hot summer days, which are five times smaller than for the control plot. The wool retains large amounts of rainwater several times its weight. The water is then slowly released, providing the growing plants a moist environment during a longer rainless pe-riod. Moreover, wool is difficult to biodegrade and maintain its properties for a long time, lasting longer than one vegetation season. Compared to straw and bark, the temperature fluctuations recorded for wool are two times smaller, and its effectiveness in water management is consid-erably better. The beneficial impact of the wool mulch ensuring favourable conditions for strawberry growth was explained by the specific wool structure and its unique properties.
Improving O&M Simulations by Integrating Vessel Motions for Floating Wind Farms
Authors: Dighe Vinit V. , Huang Lu-Jan , Montfort Jaume Hernandez , Serraris Jorrit-Jan
Published: October 2024

This study introduces an integrated methodology that incorporates vessel motion dynamics into the evaluation of operations and maintenance (O&M) costs for floating offshore wind turbines (FOWTs). By combining UWiSE, a discrete-event simulation tool, with SafeTrans, a voyage simulation software, the methodology accounts for vessel motion effects during offshore operations. The approach was demonstrated through a numerical case study at two wind farm sites, Marram Wind and Celtic Sea C, with a fictive wind farm layout of 100 × 15 MW NREL turbine on a UMaine VolturnUS-S platform. Three Major Component Replacement (MCR) strategies were assessed: Tow-to-Port (T2P), Floating-to-Floating (FTF), and Self-Hoisting Crane (SHC). The T2P strategy resulted in the highest O&M costs—94 k€/MW/year at Marram Wind and 97 k€/MW/year at Celtic Sea C—due to extended MCR durations (90-180 days), leading to lower availability (90%-94%). In contrast, the FTF and SHC strategies, which are still under development, demonstrate significantly lower costs and reduced downtime. The SHC strategy, in particular, has proven to be the most cost-effective, achieving up to a 64% reduction in costs while increasing availability to 97%-98%. The integrated approach incorporates vessel dynamics, accounting for factors such as wave direction, wave period, and vessel response to varying sea states. This allows for greater flexibility in setting operational limits, potentially permitting higher limits in favorable conditions where vessel motion impact is reduced. However, in scenarios where dynamic vessel responses lead to increased motions—such as when waves approach from the side or when the wave period is close to the vessel's natural roll period—more restrictive limits may be necessary, even if significant wave heights are lower. This flexibility or restriction highlights the importance of incorporating motion-based dynamics for emerging technologies in the evolving FOWT O&M market.
Clean Energy and Carbon Emissions in Mexico’s Electric Power Sector: Past Performance and Current Trend
Authors: Probst Oliver
Published: October 2024

The concept of clean energy was introduced by the Mexican authorities as part of the wholesale electricity market with the objectives of both measuring the progress in decarbonization and fostering emission-free and low-emission technologies. In the present work, the evolution of clean energy production for the period 2017-2023, corresponding to seven full years of operation of the electricity market, was analyzed and compared to official targets. Emission of greenhouse gases (GHG) was calculated from fuel consumption statistics. The consistency between electricity generation and fuel consumption data has been assessed. The projected short-term evolution of electricity generation and GHG emissions through 2026, locked in by decisions in the recent past, is modeled and discussed. The extent to which official clean energy figures can be considered a predictor for emissions from the power sector is discussed as well. The results are believed to be a relevant contribution for the assessment of Mexico’s progress with its national and international climate change mitigation goals.
Short-term Wind Power Forecasting Based on OMNIC and Adaptive Fractional Order Generalized Pareto Motion Model
Authors: Cai Fan , Chen Dong dong , Jiang Yuesong , Zhu Tong bo
Published: October 2024

With the rapid development of renewable energy, accurately forecasting wind power is crucial for the stable operation of power systems and effective energy management. This paper proposes a short-term wind power forecasting method based on the Orthogonalized Maximal Information Coefficient (OMNIC) combined with an Adaptive Fractional Generalized Pareto Motion (fGPm) model. The method quantifies the influence of meteorological factors on wind power prediction and identifies the optimal set and number of influencing factors. The model accounts for long-range dependence (LRD) in time series data and constructs an uncertainty model using the properties and parameters of the fractional generalized Pareto distribution (GPD), significantly improving prediction accuracy under nonlinear conditions. The proposed approach was validated using a real dataset from a wind farm in northwest China and compared with other models such as Convolutional Neural Network-Long Short-Term Memory (CNN-LSTM) and Convolutional Neural Network-Gated Recurrent Unit (CNN-GRU). Results demonstrate that the adaptive fGPm model significantly reduces wind power forecasting errors, offering high accuracy and robustness. This method provides practical value in alleviating peak voltage and frequency regulation challenges in power systems and in promoting the integration of wind power into the grid.

Background:

The purpose of this study was to explore the impact of social deprivation on preoperative characteristics and postoperative outcomes following hip arthroscopy (HA) for femoroacetabular impingement syndrome (FAIS).

Methods:

Patients undergoing primary HA for FAIS were identified, and their social deprivation index (SDI) score was assigned on the basis of the provided ZIP code. Quartiles (Q1 to Q4) were established using national percentiles, with Q4 representing patients from the areas of greatest deprivation. Patient-reported outcomes (PROs) were collected preoperatively and at a minimum follow-up of 2 years. Achievement rates for clinically meaningful outcomes, including the minimal clinically important difference (MCID), patient acceptable symptom state (PASS), and substantial clinical benefit (SCB), were determined. The incidences of revision HA and conversion to total hip arthroplasty (THA) were recorded. SDI groups were compared with respect to preoperative characteristics and postoperative outcome measures. Predictors of MCID, PASS, and SCB achievement; revision HA; and conversion to THA were identified with use of multivariable logistic regression.

Results:

In total, 2,060 hips were included, which had the following SDI distribution: Q1 = 955, Q2 = 580, Q3 = 281, and Q4 = 244. The composition of the included patients with respect to race and/or ethnicity was 85.3% Caucasian, 3.8% African American, 3.7% Hispanic, 1.7% Asian, and 5.4% “other.” Patients with more social deprivation presented at a later age and with a higher body mass index (BMI), a longer duration of preoperative hip pain, and greater joint degeneration (p ≤ 0.035 for all). The most socially deprived groups had higher proportions of African American and Hispanic individuals, less participation in physical activity, and greater prevalences of smoking, lower back pain, and Workers’ Compensation (p ≤ 0.018 for all). PRO scores and achievement of the PASS and SCB were worse among patients from areas of greater social deprivation (p ≤ 0.017 for all). Age, BMI, activity status, race and/or ethnicity classified as “other,” SDI quartile, Workers’ Compensation, preoperative back pain, duration of preoperative hip pain, and Tönnis grade were independent predictors of clinically meaningful outcome achievement, revision arthroscopy, and/or THA conversion (p ≤ 0.049 for all).

Conclusions:

Individuals with more social deprivation demonstrated inferior postoperative outcome measures. This was driven primarily by preoperative characteristics such as SDI, hip pain duration, joint degeneration, and overall health at presentation. Despite differential outcomes, patients still showed clinical improvement regardless of SDI quartile.

Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
INSIGHTS INTO THE MOHO DEPTH AND CRUSTAL CHARACTERISTICS IN THE GUELMA–CONSTANTINE BASIN: A SHORT-PERIOD SEISMIC-RECEIVER-FUNCTION PERSPECTIVE (northeastern Algeria)

Teleseismic receiver functions (RF) were extracted from data collected at eight short-period, three-component seismic recording stations over the Guelma–Constantine Basin, northeastern Algeria, to improve the understanding of crustal structure and geodynamic processes. The H-κ stacking method was used to determine the Moho depths and average vP/vS ratios at each station. Careful linear inversion of RF was performed to determine the most appropriate average shear-wave and P-wave velocity profiles at each site. Both methods have yielded highly congruent results, with Moho depths showing robust correlations with previous seismological and geophysical studies. The previously observed pattern of the increasing Moho depth from north to south in the Tell Atlas has been confirmed. Furthermore, the identified transitional nature of the Moho in the Constantine Basin is consistent with a recent study. In addition, we identify a low-velocity zone (LVZ) at approximately 20 km depth within the southern Guelma Basin, confirming previous results in the Constantine Basin and suggesting an eastward elongation of the LVZ, at least into the southern periphery of the Guelma Basin. Examination of data from the northern tip of the Hammam Debbagh–Roknia NW–SE fault, the western boundary of the Guelma pull-apart basin, revealed a shallow Moho depth (22 km), less than the basin average depth of 25 km. The LVZ observed in the lower crust (12 km) suggests the presence of partial melts, consistent with gravimetric and chemical analyses of hydrothermal sources in the area. The extensional tectonic activity along this boundary, coupled with the low-viscosity zone and low average vP/vS ratio, is potentially associated with delamination processes. The effectiveness of our approach underscores its potential as a viable alternative or complementary method for investigating variations in the Moho depth.
El reto de cerrar brechas y eliminar desiertos de atención
Authors: Ochoa-Torres Maria del Pilar , López-Ridaura Ruy
Published: October 2024

El análisis de brechas en salud, considerando la heterogeneidad estructural, nos orienta a enfocarnos en las sutiles, pero complejas variaciones locales que influyen en la utilización y aprovechamiento de recursos y la comprensión de dinámicas sociales que las crean. Actualmente, una de las brechas más notables es la distribución de la infraestructura en salud, así como de la organización de la atención médica individual y colectiva. Los indicadores realistas resultantes de los análisis de desiertos de atención son un elemento robusto para avanzar en objetivos tales como la planeación de infraestructura física, la asignación estratégica de unidades médicas móviles, la definición de zonas de cobertura, el despliegue territorial de acciones de salud pública y el desarrollo de regiones. Hacer esta herramienta parte del quehacer de la rectoría, hasta el nivel distrital, es clave para abordar eficazmente las disparidades en la atención médica y su vinculación con los riesgos colectivos para la salud.

Background: Personality disorders (PDs) are characterized by impairments in psychological functioning for which pharmacologic treatments have demonstrated limited efficacy. Psychedelics may offer a possible PD treatment, given preliminary evidence for their potential long-term positive effects on psychological functioning. However, little is known about safety or potential therapeutic effects of psychedelics among individuals with a PD. Therefore, we examined the effects of psychedelic use on mental health among individuals who reported a PD diagnosis.
Methods: Study 1 included three prospective observational studies where 21 individuals who reported a PD diagnosis completed mental health measures (depression symptoms, anxiety, and suicidal ideation [SI]) before, 2 weeks, and 4 weeks after psychedelic use. Study 2 was a prospective observational study where 55 individuals who reported a PD diagnosis completed mental health measures (anxiety, depressive symptoms, cognitive flexibility, expressive suppression, and cognitive reappraisal) before, 2-4 weeks, and 2-3 months after psychedelic use.
Results: In Study 1, all participants with high baseline risk of suicidal behavior (6.67%) became low-risk post-psychedelic use. Post-psychedelic increases in SI were rare (6.67%) with no increases to high risk of suicidal behavior. SI reduced at 4 weeks (Hedges’ g=0.52). There were few cases of clinically significant worsening anxiety (Study 1:0.0%; Study 2:7.7%-8.2%) and depression symptoms (Study 1:0.0%-7.1%; Study 2:0.0%). However, across both studies, psychedelic use was associated with reductions in anxiety (Study 1:g=-0.46–-0.57; Study 2:g=-0.52–-0.89) and depression (Study 1 g=-0.54–-0.59; Study 2 rs=.52–.57). In Study 2, there were transient increases in cognitive flexibility at 2-4 weeks (g=0.26) and sustained increases in cognitive reappraisal up to 2-3 months (g=0.36). Increases in cognitive reappraisal were associated with reductions in anxiety (r=-.33) and depression (rs=-.37).
Conclusion: For individuals who reported a PD diagnosis, psychedelic use was associated with improvements in mental health outcomes. There were no clinically significant post-psychedelic increases in SI but there were a few cases of clinically significant increases in anxiety and depression severity. The studies are limited by a small sample size, self-reported data, and lack of differentiation between PDs. Further research is needed to explore the safety and potential therapeutic effects of psychedelics among individuals with PD.
