Authors: Melo de Araújo Bruno , Sousa Ribeiro Emanuela
Published: January 2025

Museus são espaços privilegiados de comunicação na sociedade contemporânea, podendo problematizar as mais diversas temáticas e questões sociais. As religiões, vivências e quadros culturais religiosos não são uma exceção, estando presentes nos museus brasileiros através das mais diversas narrativas e estratégias comunicacionais. Contudo, chama atenção na bibliografia acadêmica a escassa quantidade de estudos que abordem a relação museu – religião em uma perspectiva mais sistêmica. Assim, este artigo apresenta um estudo exploratório acerca dos museus brasileiros que abordam temáticas religiosas, a partir dos dados disponibilizados pelo Cadastro Nacional de Museus, disponíveis na Plataforma MuseusBR, mantida pelo Instituto Brasileiro de Museus, e uma das principais bases de informação para as políticas públicas de museus no Brasil. A metodologia adotada é de natureza quali-quanti, tendo em vista que os principais dados disponibilizados pela Plataforma MuseusBR são de natureza quantitativa, contudo, as análises, por seu caráter exploratório, são de natureza qualitativa, focando na descrição das matrizes religiosas, perfis institucionais e quadros de referência cultural presentes nos museus cadastrados na referida Plataforma. Conclui-se que as matrizes religiosas mais representadas são as cristãs, seguidas pelas afrobrasileiras, contudo, o aspecto mais relevante do estudo diz respeito à análise dos quadros culturais coletivos – majoritariamente católicos – que se encontram representados em museus de arte e históricos.

Authors: Moolya Rakesh , Sushant Sukumar Bargale
Published: January 2025

Jaundice is a disorder characterized by yellowish pigmentation of the skin sclerae mucous membrane and excretions due to hyperbilirubinemia and bile pigment deposition. There is a disruption in the balance between bilirubin production and clearance. There are three different forms of jaundice hemolytic hepatocellular and obstructive. Jaundice is referred to as lsquoKamala rogarsquo in Ayurveda. Excessive intake of Ushna hot Tikshna or Pitta Prakopaka aggravating diet is the primary cause of Kamala. This results in increased pitta dosha along with the vitiation of the Mamsa muscles and Rakta blood Dhatus. The present case report discusses the details of a 28-year-old female patient who complained of Peeta yellowish discoloration of her eyes nails and urine as well as a decreased appetite fever increased liver function test values SGPT- 525 UL and SGOT- 719 UL and a total bilirubin content of 15.2 mgdL. Based on the physical examination and liver functional test results a diagnosis of Kosthashritha Kamala was made. This condition bears a striking resemblance to hepatocellular jaundice. According to Ayurveda Virechaka a purgative Rasayana a rejuvenator and Dhatuvardhaka which nourishes bodily tissues are the next steps in the treatment of Kamala Roga after Virechana. Herbomineral formulations such as Agnitundi Vati Nirocil Bhumyalaki capsule Patolokaturohindyadi Kashaya and Avipattikara Choorna should be administered internally for 30 days together with Pathya Palana. In the case presented all the parameters including the liver function test showed improvement SGOT - 39.3 UL SGPT-21 UL and total bilirubin 1.8 mgdL.

Authors: . Suraksha , Nagesh K A Sri
Published: January 2025

Respiratory distress is a condition in which the person experiences difficulty in breathing due to various infective or obstructive pathologies involving the respiratory system. Respiratory distress is often a final common pathway for various life-threatening conditions regardless of underlying cause. Hence understanding the pathology behind the presentation of respiratory distress is crucial as it is a common presenting symptom prior to death and analyzing it promptly can make a significant difference in providing high quality care for improving patientrsquos outcome. Decoding of respiratory distress is done by using Yogatantrayukti which is one of the study tools used to understand the concept of shvaasa explained in Hikkashvaasachikitsitam Adhyaya of Charaka samhita in Ayurveda. Yogatantrayukti offers structured learning approach to understand the pathology of respiratory distress which is termed as lsquoshvaasarsquo in Ayurveda. A complex and diverse perspective of shvaasa as primary disease and as a secondary symptom to any systemic disease is simplified by Yogatantrayukti. An obstructive pathology in digestive system or excretory system causes respiratory distress. Hence keen observation of these systems is also necessary while managing respiratory system. Molecular and clinical pathology of shvaasa is understood by applying yogatantrayukti to different types of shvaasa and anatomical pathology is understood by studying verses related to the causes of shvaasa.

Authors: V Naveen , Veena Mullur MS
Published: January 2025

Classification of dravyas based on karma and scientific rationality of assigning them into particular vargas or groups is one of the hallmarks of our Acharyas in Ayurveda. Shonitasthapana varga dravyas mentioned by Charaka and Vagbhata is a distinctive group for the diversity of its sources as well as actions. A critical analysis of Shonitasthapana varga dravyas based on literature review of classical texts commentators research works etc. revealed varied actions of the dravyas which can be categorized into raktavardhana raktaprasadana and raktasthambana karmas. The group includes sthavara five drugs jangama one drug oudbida two drugs and ahara dravyas two dravyas which add to the uniqueness of being used as oushada as well as pathya. The judicious use of these dravyas after ascertaining their qualities and pharmacological activities offer a wide scope for utility of these drugs in various hematological disorders.
Comparative Critical Analysis of Charakokta Yoga and Vagbhatokta Yoga for Vamini Yonivyapath with Special Reference to Luteal Phase Defect
Authors: Ural Shubha , KV Mamtha
Published: January 2025

Vamini Yonivyapath is characterised by expulsion of Shukra along with Artava from Garbhashaya six to seven days after its entry. The expulsion may be associated with Vataja Lakshanas like Ruja or Pittaja Lakshanas like Osha Chosha etc. depending on the involvement of Doshas. Luteal phase defect LPD which occurs due to inadequate progesterone response has the features of epimenorrhoea with or without dysmenorrhoea along with failed implantation or recurrent early pregnancy loss. Vatadosha Vaishamya can be correlated to increased peristalsis and Pitta Dosha Vaishamya can be related to defective secretory phase which are the pathognomonic features of LPD. Charaka and Vagbhata have explained Uthkarika and Sneha Pichu respectively as the treatment. On analysing Rasapanchaka of Yogas it is found that both the Yogas have the drugs with Doshahara property and Garbhasthapana Guna. Both the Yogas are told in the form of Sthanika Chikitsa. Vaginal administration of Yogas will have direct action on the uterus along with minimal or no systemic effects due to first pass effect. So both the Yogas might act on the uterus in the presence of LPD and help in conception.

The most common investigative action, interrogation, is presented. The article analyzes the content of this investigative action and the main strategies of its production. The main stages of production are considered and special emphasis is placed on such an important element as “psychological contact”. The ambiguity of approaches to this definition is noted, as well as the variety of ways and techniques to achieve this state and its consistency. The features of achieving psychological contact within the framework of the main typical interrogation strategies and the prospects of maintaining it throughout the investigative action are considered. The author’s attitude to understanding the essence of psychological contact and its significance for the realization of the purposes of interrogation is being formed. Some tactical techniques are analyzed to improve the effectiveness of interrogation. The authors note the need for further study of the investigative action in question from the point of view of the psychological foundations and rules of its implementation.
Problems of development of retrospective statement of outstanding universal value of the world heritage property “lake Baikal”
Authors:   Irkutsk State University, Kolobov R. Yu. ,   Irkutsk Scientific Centre of Siberian Branch of Russian Academy of Sciences
Published: January 2025

The concept of a retrospective Statement of Outstanding Universal Value of Natural World Heritage properties is critically examined using Lake Baikal as an example. The need to prepare such a statement is determined by the decisions adopted at the forty-sixth session of the World Heritage Committee. It is shown that the absence of such a declaration hinders the preparation of a management plan for Lake Baikal as a World Heritage property and an environmental impact assessment in accordance with the guidelines developed by the advisory bodies of the World Heritage Committee. The range of legal texts to be interpreted in the preparation of the retrospective wording is identified and their detailed analysis is carried out. The necessity of using the nomination documents and their evaluation prepared by the International Union for Conservation of Nature in 1996 for the preparation of the retrospective statement is demonstrated. The concept of the “attribute of a World Heritage property” and its role in the preparation of the formalisation of the outstanding universal value of Lake Baikal is examined. The deficit of scientific attention to the concept of integrity of World Heritage properties is compensated, its role in the protection of World Heritage properties is determined. It is proposed to consider in a retrospective statement the possibility of creating a transnational World Heritage property “Lake Baikal” at the expense of Lake Khubsugul and the Tunka Depression on the principle of geological integrity. One of the possibilities to implement the recommendations of the World Heritage Committee to formalise the buffer zone of the World Heritage Site “Lake Baikal” by including the territories of five settlements, which were not included in its territory according to the inscription decision, is considered. The need for systematic improvement of the legislation on the protection of World Heritage Sites is noted.
Controversial issues of the legal regulation of first aid by medical professionals

V. ,   Nizhny Novgorod Institute of Management – Branch of the Russian Academy of National Economy and State Service under the President of the Russian Federation,   Volga Region Research Medical University
Published: January 2025

It has been established that the current state of the question of the obligation to provide first aid in medical organizations and outside of them for persons with medical education is characterized by uncertainty. On the one hand, this is due to the absence of a provision in the basic law on health care that defines medical workers as subjects who are obliged to provide first aid, on the other – to the fact that subordinate normative acts assign this responsibility only to certain categories of specialists within the framework of their official duties. A comprehensive analysis of the current normative legal acts, regulating activities in the field of citizen health protection, was carried out, with the aim of correlating the concepts of “first aid” and “medical aid” in the context of the professional activity of medical workers. It has been established that there is a lack of juridical terminology in governmental normative legal acts when defining the concept of “first aid”. It also revealed the lack of a single approach when determining the duties of the categories of workers with higher and secondary medical education in terms of providing first aid as a labor function. A conclusion was made about the necessity of enshrining at the legislative level the obligation of medical workers to provide first aid when performing professional functions and introducing this obligation into the qualification characteristics of the positions of workers in the field of health care, used in the development of job instructions.
The history of the development of the right to equal access for public service in the USSR
Authors:   Irkutsk State University, Fedoseev G. D.
Published: January 2025

The article examines the development of the right to equal access to public service during the existence of the USSR, based on the general principle of equality of Soviet citizens. It is established that the Constitutions of the USSR established the general principle of equality of rights of Soviet citizens in all spheres of public life, including political life, and therefore in the field of public service. It is noted that the Soviet legislation in the field of public service activities did not have a system-forming, complex character; it was significantly characterized by a fragmentary, fragmentary nature. Attention is focused on the ideologization of the civil service, its nomenclature formation. It is established that the presence of a plurality of normative acts of various departmental orientation did not contribute to the streamlining of the public administration system and the passage of public service. It is revealed that in Soviet times, the Imperial Table of Ranks continued to operate in its methodological basis, but was gradually recognized as outdated, however, since the middle of the twentieth century, some of its provisions in the field of military service have been accepted. It is noted that during the passage of public service, employees acquired knowledge and skills of managerial activity, moral qualities; employees were tasked with a high level of service discipline, striving for loyalty party ideals. It is concluded that the regulated constitutional equality of Soviet citizens in all spheres of life formally existed in a declarative form, because the existing political regime based on prohibitive and permissive legal means did not contribute to the development of the right to equal access to public service; the established political Soviet system laid in every civil servant lawful behavior, discipline, careful attitude to documents, a sense of patriotism. It is recommended to take into account the positive experience in the field of service discipline in the activities of the modern state apparatus.

Published: January 2025

The issues of law enforcement practice of various forms and types of liability to a public partner in the framework of his participation in the implementation of projects of public-private and municipal-private partnerships in the Russian Federation in the modern period were investigated. On the basis of the analyzed judicial practice materials, the authors concluded about the features and problems of applying administrative and civil legal liability for committed offenses under Russian legislation in the field of public-private partnerships. Proposals for improving the legislation regarding the specification of forms and types of liability applied to a public partner as a participant in public-private partnership, including the need to consolidate the concept of social responsibility for both parties as participants in the type of legal relationship, have been formulated.
Features of the legal regulation of the tourist tax in the Russian Federation
Authors:   Irkutsk State University, Kolosov N. V.
Published: January 2025

The features of the legal regulation of the tourist tax in Russia are investigated. This tax was preceded by another payment – a resort fee. The article identifies and examines the differences between the tourist tax and the resort fee. The funds from the payment of the tourist tax do not have a targeted orientation, but can be spent on the development of tourist infrastructure. In this regard, it is concluded that the name of the tax is largely related not to the direction of expenditure of the income received, but to the type of economic activity subject to taxation. The article suggests that revenues from the payment of tourist tax in Russia due to the possible expansion of the geography of application, changes in the procedure for calculating the tax, and a reduction in the number of benefits may potentially be higher than from the resort fee. The analysis of the legislation on tourist tax has shown that the funds from the payment of tourist tax can really strengthen the financial base of local government, become a new significant source of formation of local budgets. At the same time, it was noted that certain elements of taxation under the tax in question need to be adjusted. For example, there is a need to expand the list of persons for whom the cost of temporary residence services is excluded from the tax base. It is proposed to include citizens who left their place of residence for reasons beyond their control (natural disasters, other circumstances of force majeure) and were forced to settle in a hotel or other place of temporary stay. Such an approach will contribute to the implementation of the general legal principle of justice.
To the issue of holding business entities administratively liable based on the results of control and supervisory activities
Authors:   Irkutsk State University, Chagin I. B.
Published: January 2025

The article analyzes the problems of law enforcement practice associated with changes in the state’s approach to the issue of administrative liability of business entities, namely, reducing the administrative burden on business through changes in the state’s approach to imposing administrative penalties and through the establishment of special grounds for initiating cases on administrative offenses against business entities. The main attention is paid to two aspects: the ambiguity of interpretation of the norms of the Code of Administrative Offenses of the Russian Federation and the impact of this uncertainty on the business environment. It is emphasized that differences in law enforcement are associated with defects in regulatory legal acts and the wrong choice of methods for interpreting the law. The variability of practice is due to the use by courts of a literal or expansive interpretation of the norms of the Code of Administrative Offenses of the Russian Federation. The solution to these problems requires a comprehensive approach that takes into account the interests of all stakeholders and a timely response from the legislator to changes in practice.
Reservations in Russian contract law: general characteristics
Authors:   Irkutsk State University, Baturina A. A.
Published: January 2025

An analysis of Russian legislation, contractual practice and doctrinal approaches regarding the use of various clauses when drawing up agreements was carried out. The most popular contractual clauses are summarized and classified into two groups depending on the presence of a particular industry in them. Reservations that have a civil legal nature and reservations that have a non-civil legal (diversified) nature are identified. The proposed division of reservations into types according to their legal nature is conditional and does not entail a categorical distinction between them. The features of certain types of reservations are clearly examined and their legal nature is analyzed. Legislative prohibitions and the limits of dispositivity in determining the content of reservations are analyzed. The conclusion is made about the universality of contractual clauses when reaching compromises between counterparties and their impact on the legal nature of the contract as a whole.
On the legal status of the russian self-employed in the labor market and in the field of social security
Authors:   Irkutsk State University, Paryagina O. A.
Published: January 2025

It is established that the Russian legislation on the special tax regime “Professional Income Tax” predetermines the specifics of the status of the self-employed in the labor market, prohibiting their participation in labor relations and restricting their entry into civil law relations with former employers within two years after the termination of the employment contract with them. Relations on the implementation of entrepreneurial activities by the self-employed are implemented within the framework of a non-standard form of employment, tend to converge with labor relations, since, in accordance with the law, the self-employed performs work or provides services, like an employee, personally. In the new legislation on employment, the employment of citizens aimed at generating income, which does not contradict the law, is correctly called labor, but the self-employed are not quite consistently classified as employed citizens. It is shown that the introduction of a tax on professional income has led to a significant reduction in shadow employment, however, business allows the substitution of civil law relations with self-employed labor relations. In this regard, the measures provided for by law to counter illegal employment were approved. Taking into account the position of the International Labor Organization on the need to ensure decent work and social protection of all categories of working citizens, as well as foreign experience in ensuring the social and labor rights of the self-employed, it is concluded that it is possible to endow the Russian self-employed primarily with labor rights in the field of collective protection – to unite, collective bargaining, strike. In order to ensure the right of the self-employed to an old-age pension, it was proposed to divide the burden of expenses on insurance pension contributions between the self-employed and their counterparties.

Published: January 2025

The analysis of the housing law on the overhaul of the common property of apartment buildings has been carried out. The important positions of the Constitutional Court of the Russian Federation are given. The new norms on the obligation to pay contributions in houses with block sections being phased in, on monitoring the technical condition of houses, on requirements for contractors, and on construction control were evaluated. The conclusion is made about the too rapid change in the Housing Code of the Russian Federation, about the unsystematic and situational nature of the changes being made. It is proposed to adopt a separate federal law or a decree of the Government of the Russian Federation and preserve in the Housing Code of the Russian Federation only the most important norms on major repairs.

Published: January 2025

This article examines the points of view of Russian pre-revolutionary scientists on the institution of joint commission of crime in the early twentieth century. During this period of time, not only works are published that are of a general commentatorial nature or include attempts at comparative analysis with the subsequent development of their own original point of view on the institution, but also works appear in which the institution of joint commission of a crime is considered from a slightly different perspective. Such research is carried out from the historical, criminological, penitentiary, criminal-sociological and criminal-statistical points of view. The institute of joint commission and the aspect of a special part of criminal law, in relation to certain types of crimes, is being investigated. Separate issues of the institution of joint commission of a crime are also being analyzed, and this is beginning to be implemented at the monographic level. The authors conclude that in recent years there has been.

Petroleum-derived plastics are widely used but pollute the environment significantly. The development of biodegradable plastics is urgently needed to be replaced. The mechanism for making bioplastic films from cassava starch-chitosan/glycerol uses a double-screw extruder process. The film took into account the multi-hydroxyl capacity of starch by combining glycerol (in a ratio of 3:1 w/w) and chitosan (at concentrations of 0.5, 1.0, and 1.5% (w/w). The impact of chitosan involvement on the characteristics of the bioplastic material was studied, including physical, thermal, mechanical, and biodegradability properties. The findings showed that using chitosan as a filler in cassava starch bioplastics resulted in bioplastic films with high compressive capacity and water resistance. The resulting biopolymer’s contact angle was increased by including C-O functional groups in the molecule, as evidenced at a wavelength of 1028 cm-1 of the FTIR spectra. The contact angle was increased from theta = 65.3059 ± 2.7936◦ to theta = 68.6047 ± 3.2391◦. An increase in tensile strength was also observed, indicating increased stiffness compared to chitosan-free bioplastics. The best bioplastic blend was the formulation of cassava starch and glycerol containing 0.5% chitosan. Bioplastic has physical properties of density 0.8625 ± 0.0277 g/mL; contact angle 68.6046 ± 3.2391◦; water uptake 11.0660 ± 0.3709%; tensile strength 2.0181 ± 0.0594 MPa; elongation 54.2243 ± 3.2623%; thermal 137.5◦C; moisture content 4.9464 ± 0.1172%; and the fastest biodegradation rate. The bioplastic synthesized in this study is readily biodegradable in the natural environment, making it highly sustainable and more environmentally friendly, and it can be a viable substitute to reduce the use of petroleum-based bioplastic.

This study explores the micromagnetic behaviour of MnFe2O4 derived from natural iron sand through the coprecipitation method, without the need for calcination. Using manganese chlo-ride and iron sand as precursors, one can create MnFe2O4. Through the utilisation of X-ray Diffraction (XRD), Scanning Electron Microscope-Energy Dispersive X-Ray (SEM-EDX), and Vibrating Sample Magnetometer (VSM), one can effectively analyse and understand the crystal structure, morphology, and magnetic properties. The crystal size was reduced by a fac-tor of 0.40 nm, as revealed by XRD crystal structure analysis. Additionally, the XRD results indicated the absence of impurities, confirming the presence of a single phase. In addition, the SEM analysis revealed that samples 1, 2, and 3 underwent agglomeration. The particles have a cubic shape. The analysis using EDX indicates that there are no other elements present in the Mn, Fe, and O. Additionally, the VSM analysis confirms that the sample exhibits magnetic hardness. Sample 1 exhibits exceptional magnetic properties, with Ms values of 217.53 emu/g, Mr 34.27 emu/g, and Hc 127.42 emu/g. Photoluminescence (PL) spectroscopy was used to observe the optical properties of MnFe2O4. Sample 1 exhibits a distinct emission spectrum at 440 nm, representing the purple band. Sample 2 displays a sharp emission spectrum at 448 nm, indicating the blue band. Lastly, Sample 3 demonstrates a clear emission spectrum at 427 nm, signifying the purple band.

Published: January 2025

In CO2 storage technology, particularly in coal seams, necessitates specialized research into numerous critical factors that are equivalent to coal seam characteristics, including porosity, permeability, rock strength (UCS: uniaxial compressive strength), Poisson ratio, and brittleness. Rock properties of the coal seam are responsible for the CO2 storage capacity. In this study, we have core samples from the borehole and employed four well-logs (within and area ∼ 1000 m × 875 m) that drilled in the coal mining project located in South Sumatra Basin, Indonesia. The goal of this study is to describe the coal seam C strata in the sub-surface that have the potential to be utilized for underground CO2 storage. In this study, we identified coal seams C from low density and gamma rays from log response data. Then, we predict porosity values from data density, velocity (Vp andVs), UCS values, and BI using petrophysical and rock physics approaches. The result of this study shows that the distribution of top depth coal seam C varies in depth 19 to 225 m with the porosity 0.086-0.138. The value of UCS 1150 1299 Pa and brittleness index 0.531-0.569 that are associated with a characteristic coal with low to medium strength and medium brittleness. The results of this preliminary analysis revealed that the coal seam layer in this region has a high potential for CO2 storage in Sumatra, Indonesia.

Authors: Koken Fikri , Ergun Halime , Uzun Yusuf
Published: January 2025

This paper investigates two types of altered Jacobsthal numbers, namely G(2)J(n) (a) and H(2)J(n) (a), which are obtained by adding or subtracting a specific value, denoted with {a}, from the square of the nth Jacobsthal numbers. These numbers exhibit a close relationship with the consecutive products of the Jacobsthal numbers. The study establishes consecutive sum-subtraction relations for the altered Jacobsthal numbers, and derives their Binet-like formulas. Furthermore, the greatest common divisor (Gcd) sequences of r-successive terms, represented by {G(2)J(n),r (a)} and {H(2)J(n),r (a)}, r ∈ {1, 2, 3, 4} are investigated. It is observed that these sequences display either a periodic or Jacobsthal structure.

Published: January 2025

The latest advances in science and technology have positioned nanomaterials at the vanguard of contemporary research. Nano silica (SiO2) is an illustrative example of a nanomaterial extensively utilized in concrete manufacturing due to its properties as a pozzolan. The objective of this study is to elucidate the characteristics of nano silica and its effect on the performance of polymer concrete through experimental methods. X-ray diffraction (XRD) tests indicate that nano silica exhibits a high amorphous phase. Consequently, nano silica enhances the C-S-H gel formation reaction, producing more robust and denser specimens. The maximum compressive strength reached 45.23 MPa when adding 0.4% nano-silica with a specific gravity of 1573.33 kg/m3. For comparison, concrete without nano silica had a maximum compressive strength of 40.05 MPa with a particular gravity of 1610.67 kg/m3. Observation using a scanning electron microscope (SEM) showed that the nano-silica mixture exhibited excellent particle distribution as an activating agent that could enhance the strength of the specimens. Nevertheless, the observed reduction in compressive strength might be affected by several factors, including particle clusters and the presence of compounds carried by the fine aggregates that influence the mechanical properties of polymer concrete. Integrating nano-silica is pivotal in enhancing the compressive strength and reducing the specific gravity of polymer concrete specimens. The increased strength and decreased specific gravity render nano silica a promising additive for polymer concrete applications.

BackgroundAdolescence is a critical period for growth and a second window of opportunity for catch-up growth after the first growth spurt that occurs during the first 1000 days of life. During adolescence, activities to build healthy nutrition may confer significant long-term benefits.ObjectiveThis cross-sectional study assessed dietary intake, nutrient adequacy, and diet quality of 303 public secondary school students in Abeokuta, Ogun State.MethodsRespondents’ anthropometry was measured and WHO Anthroplus was used to calculate the height-for-age and body mass index for-age z-scores. Dietary intake was assessed using a 24-hour diet recall questionnaire, and the Diet Quality Index-International (DQI-I) questionnaire was used to determine diet quality.ResultsExcessive intake of carbohydrates was observed among all respondents while inadequate intakes of calcium, vitamin C, and fibre were observed among 80.8%, 100%, 95.4%, and 66.2% of the respondents, respectively. The total mean score for diet quality was 58.7±6.73 out of 100. Compared to the total score of the DQI-I domains, the highest mean performance was in the moderation category (79.5%), followed by variety (72.8%), and adequacy (45.8%), with the lowest performance in the overall balance category (19.7%).ConclusionsIn conclusion, these adolescents had lower than the cut-off score for a good diet quality. Inadequacies in vegetables and fruit groups below the recommended levels contributed to low mean scores and likely to some of the deficient nutrient intakes. Interventions including regulating the food sold by vendors and nutrition education to encourage better consumption of fruits and vegetables are recommended in schools.

Published: January 2025

BackgroundSickle cell disease (SCD) is one of the commonest single gene disorders recognized as a public health priority. Slow growth is common in children with SCD due to the vicious cycle of malnutrition and infection among them. Increasing knowledge that nutritional problems are fundamental to the severity of the disease has produced interest in promoting dietary supplementation for treating these patients.ObjectiveThe objective of the present study was to assess nutritional status and associated factors in SCD patients registered at the Sickle Cell Institute Chhattisgarh, Raipur, CG, India.MethodsWe reviewed clinical data from documents/secondary records among a cohort of 671 children with SCD 0-18 years oldat the Sickle Cell Institute.ResultsOut of all 671 children included in the study, 380 (56.6%) were male. Underweight, stunting and wasting proportions were 58%, 37.7% and 38.9% respectively. 16% children had chronic malnutrition (low height for age). 62% of the malnourished children were ≥ 11 years old and38% were ≤ 10 . 64% of the children who needed hospitalization were also in the older age group. Chronic malnutrition was significantly higher among children with an O Rh+ blood group (39.8%). 26.7% had sought care in hospital before diagnosis either for blood transfusion or for a vaso-occlusive crisis.ConclusionsA significant proportion of chronic malnutrition was seen among the study population mixed with underweight, stunting and wasting. Older children with an O+Ve blood group had increased risk of hospital admission.

Published: January 2025

Background

Medial tibial stress syndrome (MTSS) is a common overuse injury characterized by activity-induced pain along the distal medial tibial border. Current best practice includes rest and progressive resistance training. However, some patients with MTSS may be unable to tolerate the loading during exercise. Blood-flow restriction training using low loads (LL-BFR) may induce similar physiological and structural adaptations as heavy resistance training but without peak loads. This could potentially allow the athlete to continue sports activities during rehabilitation.

Purpose

The purpose of this case series was to describe an exercise program utilizing LL-BFR training for athletes with running-related MTSS.

Study design

Case series

Methods

Six recreational athletes (one handball player, one soccer player, and four runners) with MTSS were recruited. Inclusion criteria included pain along the distal two-thirds medial tibial border occurring during or after activity. Exclusion criteria were symptoms of compartment syndrome, tibial stress fracture, or contraindications for BFR training. Participants underwent a progressive six-week home-based LL-BFR training intervention with three sessions per week and were allowed to continue sports activities if pain was ≤ NRS 5. Outcome measures included change in standardized running performance (distance and pain level), pain pressure threshold (algometry), and self-reported physical function.

Results

Five athletes experienced improvements in running performance (pain and/or distance) and self-reported function. One athlete sustained an injury unrelated to the LL-BFR training, and therefore the running post-test could not be completed. Adherence to exercise was high, and post-test interviews revealed positive feedback on the training method, with no side effects reported.

Conclusion

This case series demonstrated that following a therapeutic exercise program utilizing LL-BFR training improvements in pain and function were seen in athletes with MTSS. BFR may allow clinicians to prescribe lower-load exercises, facilitating continued sports participation. Future research should compare the effectiveness of exercise programs for MTSS with and without LL-BFR training.

Posterior Medial Meniscus Root Tears: Clinical Implications, Surgical Management, and Post-operative Rehabilitation Considerations.
Authors: Monson Jill K. , LaPrade Robert F.
Published: January 2025

Tears of the posterior medial meniscus root (PMMR) are common in older patients and reportedly contribute to rapid joint degeneration over time. Recognition of these tear types and the appropriate diagnosis through clinical exam and diagnostic imaging have improved significantly in recent years, as have surgical techniques to address them. Standardized post-operative rehabilitation protocols specific to PMMR repair have not been established or well understood in the scientific literature. Thus, clinicians have little guidance for managing post-operative care. Upon diagnosis of a root tear, appropriate surgical treatment, with appreciation for native anatomy and function of the meniscus root, is a critical first step for recovery. Post-operative rehabilitation protocols should account for biomechanical considerations unique to root tears, because they can destabilize the entire meniscus and compromise its native function. Rehabilitation specialists can apply known science regarding the influence of joint motion, muscle strengthening activities, gait, squatting, and progressive loading activities on the healing meniscus to guide post-operative recovery. This knowledge, complemented with existing foundational principles for sound post-operative rehabilitation, can optimize recovery for patients following PMMR repair. The purpose of this clinical commentary is to explore clinical questions related to 1) PMMR injury epidemiology, 2) diagnosis and surgical management of PMMR tears, and 3) critical considerations for safe and effective post-operative rehabilitation.

Published: January 2025

Background

The United States military strives to prepare soldiers physically and mentally for war while preventing injury and attrition. Previous research has focused on physical injury risk factors but has not prospectively examined psychological risk factors.

Purpose

This study’s purpose was to investigate whether self-efficacy is a risk factor for musculoskeletal injury in an initial military training environment and compare it to other known risk factors.

Study Design

Prospective, Longitudinal Cohort Study

Materials and Methods

Shortly after starting cadet basic training, new cadets rated self-efficacy by an 11-point questionnaire. Other risk factor data including injury history, sex, height, weight, body mass index, age, aerobic fitness, upper body muscular endurance, core muscular endurance and previous military experience were collected by self-report questionnaire and military fitness testing. The primary dependent variable was musculoskeletal injury that originated during the seven-week course. Independent variables were compared between participants who were and were not injured using Chi-squared test, t-tests, Cox regression analysis and time to injury was evaluated using Kaplan-Meyer survival analyses.

Results

Seven hundred eighty-one (65.1%) new cadets were eligible and consented to participate. Injured cadets had significantly lower self-efficacy scores (p=0.003 and p=<0.001), shorter height (p=<0.001), lower weight (p=0.036), lower push-up and plank performance (p=<0.001), slower two-mile run performance (p=<0.001), and females sustained a proportionally higher number of injuries than males (p=<0.001). Cadets with low self-efficacy, shorter height, lower hand release push-up performance, lower plank performance and slower two-mile run performance were at greater risk for musculoskeletal injury. Cadets with less self-efficacy were also less likely to continue uninjured throughout cadet basic training according to a Kaplan-Meier survival analysis (log rank test<0.002). Multivariable Cox regression revealed that only aerobic fitness predicted musculoskeletal injury (HR=1.005 [1.003-1.006], p=<0.001).

Conclusions

Participants with less self-efficacy sustained injuries earlier and more often than those with greater self-efficacy. However, aerobic fitness alone predicted future injury after controlling for all risk factors. Resolved prior injury was not a risk factor for future injury.

Published: January 2025

Background and Purpose

Anterior cruciate ligament (ACL) tears often occur due to non-contact mechanisms in landing within females. Impact loading and aberrant landings may be addressed with augmented feedback training. The purpose of this study was to identify which female athletes most readily respond to a single session of augmented feedback to attenuate vGRF, by considering baseline peak vGFR and change in vGRF during training.

Design

Repeated Measures

Methods

One hundred, forty-seven female athletes landed from 50 cm onto two force platforms with and without augmented feedback of vertical ground reaction force (vGRF), vGRF symmetry, and lower extremity position. Each performed six baseline trials and two sets of six training trials with cues. Following training, athletes completed six post-feedback trials (with no feedback) and six dual-task (transfer) trials where they randomly caught a basketball during landing. Peak vGRF was measured. Mean responses were reported for the sets of six trials. Participants were grouped based on their responses to training. Linear regression was used to indicate how well initial performance and response predicted the final response.

Results

Four groups were identified, with 107 participants showing high baseline ground reaction forces and response to training. Only 23 participants (16.4%) did not respond to training. Baseline vGRF predicted post-feedback vGRF and transfer task vGRF (R2=0.508 and R2=0.400) across all participants. When change in vGRF was assessed following two blocks of augmented feedback training, prediction of responders improved with post-feedback vGRF and transfer vGRF (R2=0.911 and R2=0.761).

Conclusions

The combination of both baseline ground reaction force and response to initial training is more accurate than baseline measures alone in identifying those who respond to training. Assessing initial response to training may be necessary to more accurately identify individuals most likely to benefit from augmented feedback training and who may require further evaluation and training.
