Authors: Dufo-López Rodolfo , Lujano-Rojas Juan M. , Artal-Sevil Jesús S. , Bernal-Agustín José L.
Published: November 2024

This study introduces a novel method for optimising the size and control strategy of grid-connected, utility-scale photovoltaic (PV) systems with battery storage aimed at energy arbitrage and frequency containment reserve (FCR) services. By applying genetic algorithms (GA), the optimal configurations of PV generators, inverters/chargers, and batteries are determined, focusing on maximising the net present value (NPV). Both DC- and AC-coupled systems are explored. The performance of each configuration is simulated over a 25-year lifespan, considering varying pricing, solar resources, battery ageing, and PV degradation. Constraints include investment costs, capacity factors, and land use. A case study conducted in Wiesenthal, Germany, is followed by sensitivity analyses, revealing that a 75% reduction in battery costs is needed to make AC-coupled PV-plus-battery systems as profitable as PV-only systems. Further analysis shows that changes in electricity and FCR pricing, as well as limits on FCR charging, can significantly impact NPV. The study confirms that integrating arbitrage and FCR services can optimize system profitability.

Introduction: The COVID-19 pandemic prompted a global shift to distance learning, profoundly affecting children's mental health. In Saudi Arabia, remote education was implemented on March 8, 2020, impacting students across various factors, such as age, vaccination status, and school system. This shift lasted between 1.5 to 2.5 years, influencing students’ experiences differently. This study explores the psychological impact of distance learning on children and adolescents, with the goal of informing mental health advocacy and guiding educational strategies in scenarios where distance learning becomes essential. Methods: We conducted a cross-sectional study using an online survey distributed to parents of children aged 6 to 18 in the major metropolitan areas of Jeddah and Riyadh. The survey collected demographic information and included the validated Arabic version of the Vanderbilt ADHD Diagnostic Rating Scale. This tool assesses behavioral challenges, anxiety, and symptoms of attention deficit hyperactivity disorder (ADHD). Results: The study found that 71.6% of families reported a positive experience with distance learning. A significant correlation was identified between parents' marital status and children's ability to cope with remote education. Interestingly, students without ADHD symptoms experienced three times more negative outcomes than those with ADHD. However, despite reporting fewer negative experiences, children with ADHD symptomatology faced heightened symptom severity and academic difficulties. The results further indicated that 5.4% of students were classified with ADHD predominantly inattentive presentation, 1.8% with predominantly hyperactive/impulsive presentation, and 3.9% with combined ADHD presentation. Additionally, 7.2% of students screened positive for oppositional defiant disorder, 1.5% for conduct disorder, and 6.6% for anxiety or depression. Conclusion: This study is the first comprehensive, multi-city investigation in Saudi Arabia to analyze the relationship between distance learning experiences, sociodemographic factors, and mental health symptoms in children. The findings provide essential insights for future research and offer a foundation for developing targeted interventions to support children’s mental health and education in the region.

Published: November 2024

Recent interest in breath methane has demonstrated considerable growth, with a 400% increase in publications per year between 2010 and 2020 compared to the previous decade. This surge has been facilitated by advancements in measurement techniques that have improved both the precision and ease of breath methane analysis. Consequently, there has been a growing appreciation for both the routes of production as well as the physiological effects of methane within the human body, shifting from a perspective of methane as an end-product of GI microbiota to viewing it as a potentially biologically active molecule with exciting potential implications for endogenous processes. The breath methane field stands at a pivotal juncture, where new technologies enable real-time, repeated measures of breath methane for the first time, paving the way for novel insights into personalized methane levels and their interplay with health. This review explores the origins, physiological effects, and measurement techniques of breath methane, highlighting potential pathways for future research.

Published: November 2024

We introduce a fully differentiable end-to-end audio transformation network designed to convert the style of one audio sample to another. This method offers three significant advantages: (a) it operates without the need for parallel utterances, transcriptions, or time alignment processes; (b) it utilizes a global conditioning mechanism, making it vocabulary agnostic and capable of transforming audio styles regardless of the target identity; and (c) it performs one-shot audio transformations without intermediate phonetic representations, thus eliminating the necessity for phonetic alignments and speaker-independent ASR networks. We assess our method against existing approaches in voice conversion and musical style transfer tasks. Subjective evaluations demonstrate the superiority of our approach. The network employs an encoder-decoder architecture that integrates neural network models known for their explainability in natural language processing tasks.
Controversial Anti-Obesity Actions of Epicatechin in Male and Female Mice Kept at Thermoneutrality
Authors: Otton Rosemari , Silva Victoria , Sousa-Filho Celso Batista Pereira , França Caroline de Paula
Published: November 2024

Recent reports have highlighted the potential anti-obesity effects of epicatechin (EC) in regulating metabolism. Most studies have primarily used rodent models housed at standard temperatures (ST) 22°C ± 2°C. However, these mice may experience chronic cold exposure at ST, which can influence energy metabolism. Housing mice at thermoneutrality (TN) 28°C ± 2°C could provide a more accurate representation of human temperature conditions. Additionally, many studies focus solely on male animals, overlooking the significance of considering sex differences in the investigation of physiological and metabolic dysregulation. In our trial, we used both male and female C57Bl/6 mice, including lean and obese individuals. The mice were treated with either 12 mg or 20 mg of EC/kg of body weight (administered by gavage) over 12 weeks, five days a week, and were housed at either ST or TN. Contrary to previous reports, we found no anti-obesity effects from EC in either male or female mice at both doses. The mice exhibited similar weight gain, adipose tissue sizes, biochemical profiles, and liver fat accumulation when compared to obese, untreated animals. Furthermore, obese male mice supplemented with 20 mg of EC and housed at TN showed increased subcutaneous white adipose tissue (scWAT) weight and worsened glucose tolerance compared to their non-EC-treated counterparts. In conclusion, epicatechin administered by gavage did not improve obesity, liver steatosis, or insulin resistance in either male or female obese mice housed at ST or TN. This suggests that the route of administration and the EC dosage could influence its anti-obesity effects.
Current Account Sustainability. A Non Linear Approach. The Cases of Germany, China, and the USA
Authors: Poulakis Thanos , Kyrkilis Dimitrios
Published: November 2024

This paper examines the sustainability of the current account balances for three leading economies that play significant roles in global financial and geopolitical developments: China, the US, and Germany. Specifically, the alignment of the US, German, and Chinese current accounts with their intertemporal budget constraints is analyzed. The stationarity of the current account is considered a sufficient condition for defining sustainability. However, it is argued that the common assumption of a linear process for the current account under the alternative hypothesis of stationarity may not accurately reflect reality, as the current account may exhibit nonlinear behavior. Therefore, both linear and nonlinear unit root tests are employed to investigate current account sustainability. The objective is to determine whether the current account balances of China, Germany, and the US are sustainable independently or if achieving sustainability necessitates government intervention.

Field crops such as wheat, alfalfa, ryegrass, and corn play a vital role in agriculture and livestock production, particularly in the Kahramanmaras plain, irrigated by the Aksu River and the Sır Dam. Given the critical importance of irrigation water quality for optimal crop production, this study aimed to assess the impact of Karasu, Erkenez, and Oklu creeks on the water quality of the Aksu River and Sır Dam, and its subsequent effects on the germination and seedling growth of key field crop species grown in the region. The experiment was conducted in 2017 at the Field Crops Laboratory, Faculty of Agriculture, Kahramanmaras Sutcu Imam University, Turkey, using a completely randomized design (CRD) with four replications. Seeds were germinated using water samples collected from various locations within the dam basin, with tap water serving as the control. Before germination, the water samples were analyzed for concentrations of heavy metals, including copper (Cu), iron (Fe), lead (Pb), chromium (Cr), arsenic (As), nickel (Ni), and cadmium (Cd). Seeds exposed to different water treatments were germinated in a climate chamber at 20 ± 1°C. Over two weeks, daily germination counts were recorded, and at the end of the experiment, total germination and seedling growth were measured. The results demonstrated that irrigation water contaminated with heavy metals significantly affected seed germination and seedling growth. Notably, water from Karasu Creek exhibited the most pronounced negative impact on all germination and growth parameters in the tested crops.

Published: November 2024

Background: Parkinson’s disease (PD) is a neurodegenerative disorder characterised by a high prevalence of sporadic cases. Various molecular mechanisms are involved in its pathogenesis. This pilot study aimed to identify potential risk and protective human leukocyte antigen (HLA) alleles in PD, discover candidate alleles for further research, and evaluate potential blood biomarkers. Methods: A total of 43 PD patients and 79 unrelated controls were enrolled in the study. We analysed the polymorphism of HLA-DRB1, HLA-DQA1 and HLA-DQB1 alleles, and the blood levels of biomarkers such as S100 calcium-binding protein A9 (S1000A9), kynurenic acid (KYNA), neurofilament light chain (NfL), and glutamate decarboxylase (GAD1). Results: We found that the frequencies of the HLA-DRB1*04, -DQA1*02:01, and -DQA1*03:01 alleles were significantly higher in the PD patients than in the controls, suggesting that these alleles are potential risk factors. Furthermore, the HLA-DQA1*02:01 allele was detected more frequently in the PD group when the disease onset was at 60 years or older. On the contrary, the HLA-DRB1*01 and HLA-DQA1*05:01 alleles were less common in the PD patients, indicating a possible protective effect. Regarding biomarkers, the blood levels of S100 calcium-binding protein A9 were significantly higher and the kynurenic acid levels were significantly lower in the PD group. The NfL levels were also higher in the PD group but did not reach statistical significance, possibly due to the sensitivity limitations of the ELISA method used. The GAD1 levels showed no significant differences between the two groups. Conclusions: Our findings prove that the HLA-DRB1*01 and -DRB1*04 alleles and the HLA-DQA1*02:01, -DQA1*03:01, and -DQA1*05:01 alleles are associated with PD. Moreover, S100 calcium-binding protein A9 and kynurenic acid can be considered potential blood biomarkers for PD. These findings contribute to the growing body of knowledge on PD and offer new directions for further research in Latvian cohorts.

Published: November 2024

Hard yellow maize is a crucial crop in Peruvian agriculture, playing a significant role in food security and livestock production. However, intensive fertilization practices in agronomic management have negatively impacted soil health. To explore more sustainable agricultural technologies, researchers have investigated using microorganisms to enhance plant growth. This study assessed the synergistic effects of microbial inoculants and mineral fertilization on INIA 619 and Dekal B-7088 maize varieties' yield and nutritional quality. A split-plot design was employed, incorporating four inoculation treatments—no inoculant, Bacillus subtilis, Trichoderma viride, and Pseudomonas putida—combined with fertilization levels of 0%, 50%, 75%, and 100%. The findings revealed that Bacillus subtilis boosted yields by 13.1% in INIA 619 and 55.5% in Dekal B-7088. Additionally, combined with 100% fertilization, microbial inoculation increased protein content by 47% and carbohydrates by 6% in INIA 619, while maintaining nutritional quality with 75% fertilization. Similarly, in Dekal B-7088, inoculation with total fertilization enhanced protein content by 54% and fiber by 27%. These results demonstrate that microbial inoculation can reduce mineral fertilization by up to 25% while sustaining high yields and improving the nutritional quality of maize.
RHS and Quantum Mechanics: Some Extra Examples
Authors: Blazquez Maria , Gadella Manuel , Jimenez Trejo Gerardo
Published: November 2024

The rigged Hilbert spaces (RHS) are the right mathematical context which includes many tools used in quantum physics, or even in some chaotic classical systems. It is particularly interesting that in RHS coexist discrete and continuous basis, abstract basis along basis of special functions and representations of Lie algebras of symmetries by continuous operators. This is not possible in Hilbert spaces. In the present paper, we study a model showing all these features, based on the one dimensional P\"oschl-Teller Hamiltonian. Also, RHS support representations of all kinds of ladder operators as continuous mappings. We give an interesting example based on one dimensional Hamiltonians with an infinite chain of SUSY partners, in which the factorization of Hamiltonians by continuous operators on RHS plays a crucial role.

Published: November 2024

Maize productivity has remained low and has worsened in the wake of a changing climate, resulting in new invasive pests, with earlier designated minor pests becoming major and pathogens transported by pests and/or entering their feeding sites. A study was conducted in 2021 in Kisumu and Makueni counties, Kenya, to determine how different maize cropping systems affect insect diversity, insect damage to maize, and their ability to spread Aspergillus spores in pre-harvest maize. The field experiments used a randomized complete block design with the four treatments maize monocrop, maize intercropped with beans, maize-bean intercrop with Trichoderma harzianum, and push-pull technology. The fall armyworm Spodoptera frugiperda (J.E Smith) (Lepidoptera: Noctuidae) was the most damaging pest in the two regions. The push-pull and the maize-bean intercropping technologies significantly reduced the maize foliage and ear damage caused by the Fall armyworm. Beetles passively spread mycotoxigenic Aspergillus spp. and Fusarium verticillioides on pre-harvest maize. Maize weevils, Sitophilus zeamais Motschulsky, 1855 (Coleoptera: Curculionidae) and Carpophilus dimidiatus Fabricius, 1792 (Coleoptera: Nitidulidae), earwigs, Forficula spp. L. (Dermaptera: Forficulidae) and carpenter ants, Camponotus spp. L. (Hymenoptera: Formicidae) carried the highest number of spores on their exoskeletons. The study stresses the role of insects in the spread of fungi on pre-harvest maize and their possible control by intercropping and other cropping technologies.
Self-Supervised Foundation Model for Template Matching
Authors: Hristov Anton , Dimov Dimo , Nisheva-Pavlova Maria
Published: November 2024

Finding a template location in query image is a fundamental problem in many computer vision applications, such as localization of known objects, image registration, image matching and object tracking. Currently available methods fail when not enough training data is available or big variations in the textures, different modalities and weak visual features exist in the images, leading to limited applications on real-world tasks. We introduce Self-Supervised Foundation Model for Template Matching (Self-TM), a novel end-to-end approach for self-supervised learning template matching. The idea behind Self-TM is to learn hierarchical features incorporating localization properties from images without any annotations. As going deeper in the convolutional neural network (CNN) layers, their filters begin to react to more complex structures and their receptive fields increase. This leads to loss of localization information in contrast to the early layers. The hierarchical propagation of the last layers activations back to the first layer results in precise template localization. Due to its zero-shot generalization capabilities on tasks such as image retrieval, dense template matching and sparse image matching our pre-trained model can be classified as a foundation one.

Published: November 2024

The article discusses the current problem of reducing power dissipation in global communication lines while maintaining high performance. With the increasing complexity of system on chip, power consumption has become a major issue in system design. The main source of dynamic power dissipation in digital circuits is buses. Bus switching activity accounts for a significant portion of the total power dissipation. One effective method for reducing switching activity during device-to-device or on-chip communication is the use of low-power encoding techniques. Encoding and decoding methods have been studied to reduce the number of switching on buses. The purpose of the article is to develop a method for constructing a set of unit distance codes, determining the types of code transformations, and criteria for assessing the effectiveness of codes. Research results. A method for constructively enumerating unit distance codes has been developed, based on an invariant approach and the construction of a system of various representatives. Estimates of their number were obtained, characteristics were determined, and catalogs of typical representatives were generated. Conclusion. Application of the developed method will allow us to analyze and select codes with the best properties and, as a result, obtain better results in terms of network delays, energy costs and other design limitations for computer systems.

Published: November 2024

Topicality. IoT information processing is usually performed in a cloud environment. However, this creates problems associated with delays in data transfer to the cloud. It is especially important to reduce these delays when processing operational IoT transactions. This can be achieved by transferring part of the calculations to IoT peripheral devices. However, it is necessary to take into account the specific features of embedded IoT systems. The subject of study in the article is methods for transferring the load to IoT peripheral devices. The purpose of the article is to reduce the execution time of operational IoT transactions by increasing the efficiency of the system infrastructure by transferring part of the computing load to IoT peripheral devices. The following results were obtained. A conclusion has been made about the possibility of constructing a distributed information system based on Internet of Things devices. A model of a computing node has been formed, which made it possible to specify a separate computing node, taking into account its location and functioning features. A method for distributing tasks among the nodes of a distributed information system has been developed. The method allows taking into account the features of each computing node and the state of communication channels between them. The developed algorithm for implementing the method is based on the analysis of a stationary or non-stationary environment and changing the greedy strategy of the agent. Conclusion. Studies of the effectiveness of the proposed method have been conducted. The simulation results have shown that the proposed method can significantly reduce the processing time of operational transactions.

Authors: İnal Özgü , Tunçer Berna
Published: November 2024

Aim: The study has been conceived to investigate motivation and barriers of physical activity participation in young adults. Material and Methods: Two hundred and twenty-two university students aged 19-24 years included in this study. Demographic information form, Motivation Scale For Participation In Physical Activity (MSPPA) and Physical Activity Barriers Questionnaire (PABQ) were used in the study. Results: When the correlation between physical activity barriers and motivation to participate in physical activity was evaluated, a moderate negative correlation was found between PABQ Total and MSPPA Total (r=-0.41, p<0.01). It was found that; regular physical activity during the university period had a negative correlation with PABQ Total (r=-0.26; p<0.01) and a positive correlation with MSPPA Total (r=0.14, p=0.04). Conclusion: Findings showed that motivation to participate in physical activity was associated with physical activity barriers in many aspects. The study also demonstrated that individuals in this age group had a high motivation for physical activity, but the rates of regular physical activity were insufficient.

Gereç ve Yöntem: Palyatif bakım hastalarında fizyoterapi uygulanan çalışmalar incelenmiştir.
Bulgular: Rehabilitasyon ve palyatif bakım ekibi üyeleri hasta bakımında birçok yaklaşımı ve hedefi paylaşırlar. Fizyoterapistler, hastalık evresine bakılmaksızın ve hatta yaşamın sonuna yaklaşırken palyatif bakım alan birçok hastanın kapsamlı bakım planlarına değer katar. Fiziksel değerlendirme işlevi etkileyen yeni veya kötüleşen bozuklukları ortaya çıkarabilir. Bireysel egzersiz programları, terapiler, ekipman ve yardımcı cihaz reçeteleri ve diğer modaliteler dahil olmak üzere rehabilitasyon müdahaleleri hasta bakımında yardımcı olabilir.
Sonuç: Ciddi ve yaşamı sınırlayan hastalıkları olan hastalar genellikle yorgunluk, duygu durum bozuklukları, nefes darlığı, ağrı ve fonksiyonel düşüş gibi ortak bir semptom alt kümesi yaşarlar. Tüm bu semptomlar azalmış yaşam kalitesine katkıda bulunur. Birçok hasta mümkün olduğunca işlevsel bağımsızlığı korumak ve bakıcıları üzerindeki yükü azaltmak istemektedir. Fizyoterapi yaşam kalitesini artırmak için etkili bir stratejidir. Her ikisi de fiziksel işlevi optimize etmek ve hasta memnuniyeti sonuçları için birlikte çalıştığından bu karmaşık hasta popülasyonlarının bakımında palyatif bakım ekibi ve fizyoterapistler arasında iş birliğinin artması gerektiğini savunuyoruz.

Authors: Şahin Murat , Aksoy Songül
Published: November 2024

Objective: The aim of this study is to collect the WBT data of healthy middle ears and to examine the age-related changes in WBT results.Material and Methods: 60 individuals with normal hearing aged 20–49 years were included in the study. Three age groups comprising 20 individuals were formed for each decade. WBT measurements were performed. Results: There is no statistically significant difference between the groups in terms of WBT values (p>0.05). The WBT results are not age-dependent within the age range of 20–49 years. There is no statistically significant difference between pressurized and nonpressurized absorbance values (p>0.05).Conclusion: We concluded that there was no difference between pressurized and nonpressurized absorbance values in individuals with a healthy middle ear and the WBT results did not change with age in the 20–49 age range due to the lack of statistical significance. As it provides lot of information with a single measurement, Wideband tympanometry can be safely used in the clinic as a part of an audiological test set. Studies can be conducted to determine the specificity and sensitivity of WBT in adult and pediatric patient groups.

Published: November 2024

Objective: The aim of this study was to compare the fatigue, physical activity, sleep quality, and anxiety levels in patients with Multiple Sclerosis (PwMS) during the outbreak of COVID-19 compared to pre-COVID-19 outbreak.
Material and Methods: In this study, 48 MS patients, whom we routinely followed up, were contacted by e-mail. The participants were asked to complete an online survey that includes sociodemographic data form, the Fatigue Severity Scale (FSS), the International Physical Activity Questionnaire (IPAQ), the Pittsburgh Sleep Quality Index (PSQI), and the anxiety part of the Hospital Anxiety and Depression Scale (HADS). Also, the patients' social isolation time and with whom they lived during this period were recorded.
Results: Thirty PwMS, aged 21-58 years, volunteered to participate in the study. We found that physical activity and sleep quality decreased and fatigue increased in the COVID-19 pandemic period (p0.05).
Conclusion: The results of this cross-sectional study suggest that physical activity, sleep quality, and fatigue were more negatively compared to the pre-pandemic values, but no change was observed in anxiety status.

Authors: Sucato Daniel J. , Brabham Case E. , De La Rocha Adriana , Podeszwa David A. , Karol Lori A.
Published: November 2024

Background:

Salter osteotomy (SO) and Pemberton acetabuloplasty (PA) are procedures to treat skeletally immature patients with developmental dysplasia of the hip (DDH). The purpose of this study was to compare the radiographic results and rate of residual dysplasia (RD) after treatment with SO and with PA.

Methods:

This was a retrospective analysis of pediatric patients treated with either SO or PA for DDH between 1980 and 2013 who were skeletally mature at the time of follow-up. The preoperative and postoperative acetabular index (AI) and postoperative lateral center-edge angle (LCEA) and anterior center-edge angle (ACEA) were collected. RD was defined as an LCEA or ACEA of <20° or an acetabular inclination (AIn) of >15° at skeletal maturity. Continuous variables were compared between treatment groups with 2-sample t tests, and categorical variables were compared using chi-square tests. Multivariable analysis was used to identify risk factors for RD with p < 0.05.

Results:

The study included 113 hips in 102 patients with a mean follow-up of 10.5 years. The SO group had 73 hips treated at a mean patient age of 5.4 years, and the PA group had 40 hips treated at a mean age of 5.3 years. The preoperative AI did not differ between the treatment groups (32.2° versus 31.3°, p = 0.658), nor did the immediate postoperative AI (20.0° versus 20.2°, p = 0.459). At the time of final follow-up, the SO group had a significantly smaller AIn (8.6° versus 13.2°, p = 0.001), a trend toward a greater LCEA (26.2° versus 21.6°, p = 0.056), and a similar ACEA (24.1° versus 26.1°, p = 0.808). By the abovementioned definition, 36 hips (31.9%) had evidence of RD, with a lower rate in the SO group (26.0% versus 42.5%, p = 0.07). Patients who had a positive family history of hip dysplasia were more likely to have RD (odds ratio = 4.311, 95% confidence interval = 1.125 to 16.528).

Conclusions:

Patients with RD could be effectively treated with either SO or PA, with overall good radiographic outcomes. However, SO achieved a better AI and may thus yield better long-term health of the affected hip.

Level of Evidence:

Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
Endoscopic Treatment of Proximal Vastus Lateralis Myo-Aponeurosis Rupture in a Professional Skier
Authors: Bonin Nicolas , Ayeni Olufemi R.
Published: November 2024

Case:

We present the case of a 33-year-old World Cup giant slalom skier treated by endoscopically assisted proximal vastus lateralis (VL) release for persistent lateral thigh pain, due to a VL proximal myo-aponeurosis rupture. At the completion of rehabilitation, he was able to return to Olympic-level competition following surgery and was still symptom free at the 3-year follow-up.

Conclusion:

The unusual location of this injury and the symptoms and physical examination are of interest. The endoscopic release of the VL proximal insertion allowed a rapid and lasting result with a return to competitive skiing at an elite level.

Published: November 2024

Case:

Fourteen-year-old boy, history of autism presented with bilateral knee instability. Imaging revealed bilateral anterior cruciate ligament (ACL) insufficiency, 20° of posterior tibial slope (PTS) on the right and 18° on the left. A guided growth technique using anterior placed tension band plates was used to correct the PTS. At 22 months, the PTS corrected to 5.5° on the right and 6° on the left. The patient's knee stability improved, and he resumed activities at 30 months.

Conclusion:

Pediatric ACL insufficiency in the setting of elevated PTS can be successfully corrected with a guided growth technique.

Objective. To investigate gender-specific patterns of sleep problems among adults residing in urban areas of Mexico City. Materials and methods. Utilizing cross-sectional analysis, data from the Tlalpan 2020 Cohort, comprising 2 859 healthy individuals, were examined. Clinical, anthropometric, sociodemographic, and socioeconomic factors were assessed, and sleep problems were evaluated using the Spanish version of the MOS-Sleep Scale. Results. Elevated rates of sleep problems were found among women, with factors such as maternity (odds ratio [OR] 1.3; 95% confidence intervals [95%CI] 1.0,1.5), passive smoking (1.4; 1.1,1.8), and educational level (1.7; 1.4,2.0) significantly increasing the likelihood of sleep problems. For men, risk factors included smoking (1.4; 1.1,1.8), and lack of access to medical attention (1.3; 1.1,1.4). Conclusion. This study exhibited significant gender disparities in sleep patterns, highlighting the impact of socioeconomic factors on women’s sleep. These findings emphasize the importance of addressing gender-specific influences in both sleep research and healthcare interventions.

Published: November 2024

Las poblaciones indígenas en México han sido invisibilizadas en las estadísticas de salud. Aunque en 1992 se reconoció la pluriculturalidad del país, sólo desde 2010 es obligatorio registrar la pertenencia étnica en el Sistema de Información en Salud. A pesar de los intentos para registrar, monitorear y evaluar la salud indígena, hace falta redoblar esfuerzos para visibilizar sus condiciones de salud, las disparidades que enfrentan respecto a la población nacional, sus determinantes y la respuesta del sistema de salud para atenderlas. En este contexto, el Instituto Nacional de Salud Pública creó, en 2022, como parte del Programa Institucional Salud de los Pueblos Indígenas, el Observatorio de la Salud de los Pueblos Indígenas, con el objetivo de responder mejor a sus necesidades y reducir las desigualdades que enfrenta este grupo poblacional.
