Abstract Klebsiella spp. is an opportunistic pathogen which poses a significant threat to public health, especially due to antimicrobial resistance and biofilm formation. This study aimed to determine the antibiotic resistance profile, biofilm formation and β-lactamases production in Klebsiella spp. strains from clinical samples obtained from hospitalized patients, health professionals and hospital environment of intensive care units (ICUs) in Brazilian Amazon. The strains were obtained from clinical samples in different hospitals and identified using molecular techniques. The antimicrobial susceptibility was investigated via disk diffusion and microdilution. Biofilm formation was evaluated using a microtiter plate assay, while the extended-spectrum β-lactamases (ESBL) and carbapenemases production was assessed via disk approximation tests and combined disk tests, respectively. A total of 226 Klebsiella spp. strains were identified, with 141 coming from patients hospitalized in ICUs, 54 from healthcare workers, and 31 from hospital structures. Collection sites that showed the highest frequencies of isolated bacteria were the armpit (43,3%), oral cavity (42.6%), nasal cavity (70.4%), beds (54.8%) and mechanical ventilation (19.4%). Klebsiella spp. isolates from hospitalized patients and hospital ICU environments showed a high frequency of resistance (>50%) to the antibiotics, cefuroxime, cefotaxime, ceftriaxone, ciprofloxacin and aztreonam, and greater sensitivity (>70%) to carbapenems, amikacin and polymyxin B. Samples obtained from hospital structures (74.2%) and patients (51.8%) exhibited a high rate of multidrug resistant (MDR) isolates. In addition, 29% of Klebsiella isolates were found to produce ESBL and 15.5% carbapenemases. Biofilm formation was observed in 58.4% (132/226) of the isolates, with percentages of 64.5% (91/141) in hospitalized patients, 51.6% (16/31) on hospital structures, and 46.3% (25/54) among healthcare professionals. These results indicated a high percentage of antibiotics resistance and MDR in isolates from hospital structures and patients, which also showed ability to produce biofilms, ESBL and carbapenemases. Our findings reinforce the need to monitor resistance and adopt measures aimed at preventing the spread of MDR bacteria in ICUs.

Published: February 2025

Resumo O presente artigo analisa as disputas discursivas em torno da mobilidade urbana em Belo Horizonte. Partindo de antecedentes e contextos da proposta de tarifa zero e apoiando-se em bases pragmatistas para compreensão da construção discursiva de políticas públicas, seus problemas, públicos e arenas, o estudo tem caráter exploratório e articula a seguinte pergunta: quais são os distintos discursos sobre o transporte coletivo e como contribuem para a conformação da política de mobilidade urbana em Belo Horizonte? O artigo analisa o contexto de crise do financiamento do transporte público e a solução do subsídio tarifário, evidenciando os sentidos em tensão em tal política de financiamento. Segue, então, para a análise qualitativa de matérias jornalísticas no período de disputa para a adoção do subsídio tarifário em BH, compreendendo os fóruns midiáticos como instrumentos de discussão política e de justificação da ação pública. Os discursos revelam ao menos dois projetos políticos subjacentes ao conflito: um primeiro, sustentado em premissas técnicas e neoliberais, e articulado a partir da eficiência dos gastos públicos; e um segundo, amparado por uma noção de “vida sem catracas” e articulado a partir das premissas do direito à cidade.

The burrow structure of Minuca osa (Brachyura: Ocypodidae) from the eastern Montijo Gulf, Panamanian Pacific
Authors: Lombardo Roberto C.
Published: February 2025

Abstract Between November 2022 and March 2023, thirty-seven Minuca osa burrow plaster casts were poured while simultaneously collecting biometric data of the occupants in Ponuga, eastern Montijo Gulf, Panamanian Pacific. Casts revealed a highly variable structure with straight and spiral sections, reaching depths down to 122 cm (mean ± SD = 73.20 ± 28.66 cm). Burrow depth and length did not differ between sexes; however, males exhibited larger burrow diameter (25.9 ± 4.61 mm) compared to females (19.48 ± 1.65 mm; Mann-Whitney, P < 0.001). Male carapace width (23.4 ± 2.15 mm) surpassed that of females (18.42 ± 1.73 mm; Mann‐Whitney, P < 0.001). Female carapace length (r 2 = 0.793) and male chela length (r 2 = 0.769) were correlated to diameter. This study presents the first description of M. osa burrow structure, providing valuable insights into this understudied species.

The Role of the Occupational Therapist in Case Management in South Africa
Authors: Govender Kreshnee , Christopher Chantal , Lingah Thanalutchmy
Published: February 2025

Â 
Introduction: Case Management is fundamental in managed healthcare and has been identified as an established practice delivered by varied health professionals. The aim of the study was to identify the occupational therapist's role and scope of practice in case management in South Africa.
Method: A questionnaire was developed and distributed via Surveymonkey which yielded quantitative and qualitative data.
Results: Occupational therapists are in involved in case manager functions and the extent and intensity of involvement depends on the practice area. More than half the respondents (n=43 i.e. 64%) indicated frequent involvement in case management. The majority of respondents indicated that academic preparation in case management would be beneficial at post-graduate level (64%).
Conclusions: Case management has been implemented by occupational therapists operationally in disability management and as a component of vocational rehabilitation. A high percentage are involved in advocacy for the client, collaboration with the employer in transitioning the client back to work and the coordination of services to enable a work reintegration which are all recognised as case manager functions with an emphasis on occupational performance.  Further research is suggested for formalised training in the field to strengthen the occupational therapist as case manager and for the use of a standard practice in vocational rehabilitation.
Digital apartheid and the effect of mobile technology during rural fieldwork
Authors: Barnard-Ashton Paula , Adams Fasloen , Rothberg Alan , McInerney Patricia
Published: February 2025

Fourth year occupational therapy students at the University of the Witwatersrand attend a three-week rural fieldwork placement. During this time, they are in a resource-limited environment with limited access to their usual Virtual Learning Environment (VLE) in a blended learning curriculum, thereby contributing to 'digital apartheid' between students from different socioeconomic backgrounds.
This study investigates the effect of mobile technology during rural fieldwork to address 'digital apartheid'.
A self-reporting pre-test post-test survey design was used. Students self-evaluated their understanding of fieldwork learning objectives at the start of the year and again midyear. Rural fieldwork marks were collected mid-year. The experimental group (n1=13) accessed the VLE via the mobile technology, whereas the control group (n0=7) did not. Data were analysed for significance and effect size.
While there was no significant difference in the student marks (p=0.27), there was a significant effect on self-evaluated knowledge gain for the experimental group's rural fieldwork learning objectives (d=2.02) which was a notably larger effect size than their other fieldwork learning objectives (d=1.36) and that of the control group's learning objectives. The use of mobile technology during rural fieldwork was a successful strategy towards 'digital democracy' by allowing students equal access to access the VLE.
Hand health for all: do undergraduate occupational therapy hand curricula respond to the call?
Authors: Van Stormbroek Kirsty , Buchanan Helen
Published: February 2025

Introduction:  The call for higher education curricula to be responsive to the South African context is growing louder. Injuries to the hand are common in South Africa and intervention is often provided by novice occupational therapists who may work in complex practice contexts with limited supervision. Comprehensive hand health practice addresses both the biomedical and occupational dimensions of the human hand. Undergraduate education programmes should be responsive to this reality in preparing graduates adequately for hand practice. This article describes the content of hand curricula within occupational therapy undergraduate programmes in South Africa with the purpose of considering how they prepare graduates for the practice realities they may face during community service.
Methods:  A descriptive cross-sectional survey design was used with an online questionnaire aimed at determining the nature and extent of hand curricula presented in South African undergraduate occupational therapy programmes (n=8). Data were analysed using Stata 12.
Results: Time allocated to hand impairments varied considerably across universities. While assessment of biomedical performance components were taught by all universities, the occupational perspective was limited. The range and number of hand conditions and treatment modalities that were taught also varied.
Findings are discussed against the contextual realities of practice in South Africa, primary health care policy, and national and international minimum standards for the education of occupational therapists. Core aspects of a hand curriculum are proposed as a means to enhance comprehensive hand health practice.

Published: February 2025

Background: The seaweed industry has experienced rapid growth, especially in the production of food, feed, biofuels, and biochemicals. Indonesia has become the largest exporter of fresh, frozen, and dried seaweed; However, carrageenan derivative products are still limited. The demand for seaweed continues to increase, but the supply of seaweed raw materials for carrageenan-derived products has not met international standards, so it has failed to meet the demand in full. Seaweed production is exported as raw materials, and its added value has not been enjoyed by farmers, producers, local governments, and other stakeholders. The demand for carrageenan, especially as a raw material for the food industry, is increasing, which emphasizes the importance of seaweed supply.Purpose: This research aims to manage the supply of seaweed as raw material for carrageenan derivative products in the seaweed production center area in Laikang Village, Takalar Regency.Design/methodology/approach: This study uses qualitative analysis of interactive models Miles, Huberman, and Saldana. Techniques used include semi-structured interviews, where the implementation is more flexible to identify problems openly. Respondents were asked to provide more detailed information and ideas, which were then observedFindings/Results: The results of the study show that the management of seaweed supply in Laikang Village is sufficient in terms of quantity but still lacks in terms of quality according to the demand of the agroindustry.Conclusion: In order to improve seaweed quality through more inexpensive seeds, improved distribution, and eco-friendly practice training, government help is essential. Strategic planning in market research and supply management is emphasized in this study, which projects the seaweed supply for carrageenan derivatives in Laikang. While downstream processing regulations can optimize economic potential by minimizing the export of raw materials, effective supplyOriginality/value (State of the art): This study makes an original contribution by investigating a problem that is not clearly defined, poorly understood, or under-investigated (exploratory), thereby gaining a better understanding of the problems that exist in the supply of carrageenan raw materials in Laikang village., so that can provide an objective picture of the real conditions of the subjects being studied.

Avoidance motivation and chinese physical education students' athletic performance: the longitudinal mediation effect of self-handicapping
Authors: Li Yaming , Saibon Jamalsafri Bin , Mo Wei Long , Xu Jing Ya
Published: February 2025

This study explores the bidirectional relationship between avoidance motivation and athletic performance in physical education students and the longitudinal mediating role of self-handicapping. We seek to reveal the mechanisms through which avoidance motivation and self-handicapping influence athletic performance in physical education students, providing empirical support for the development of outstanding athletes and sports education professionals.A longitudinal study was conducted using a questionnaire survey method with 1,147 physical education students over two years, with assessments occurring once per year. Data were analyzed using structural equation modeling.Results: (1) Athletic performance at the first measurement (T1) significantly negatively predicted avoidance motivation at the third measurement (T3) (β = -0.07, p < 0.05). Avoidance motivation at T1 did not significantly predict athletic performance at T3 (β = 0.004, p > 0.05). (2) Path analysis revealed that self-handicapping plays a longitudinal mediating role in the bidirectional relationship between avoidance motivation and athletic performance. The model showed good fit indices (χ² = 53.514, df = 7, CFI = .988, TLI = .952, RMSEA = .076, SRMR = .024).Therefore, the following conclusions are drawn:(1) Athletic performance significantly negatively predicts subsequent avoidance motivation in physical education students, while avoidance motivation does not significantly predict subsequent athletic performance. (2) Self-handicapping is a longitudinal mediator between athletic performance and avoidance motivation. Athletic performance can directly affect avoidance motivation and indirectly influence it through self-handicapping.

Authors: Rojo-Ramos Jorge , Gómez Paniagua Santiago , García-Guillen María José , Galán-Arroyo Carmen
Published: February 2025

Los últimos datos sobre inactividad física entre los jóvenes universitarios suscitan preocupación por la calidad de vida y el desarrollo de esta población. La bibliografía científica señala que la motivación para la práctica de actividad física es influenciada en gran medida por el sexo del alumnado. El objetivo de este estudio es analizar las diferencias existentes en la motivación para la práctica de actividad física en universitarios extremeños según su sexo. Para ello, se aplicó la Escala de Medición de los Motivos de Actividad Física (MPAM-R). Con el fin de explorar las posibles diferencias entre ambos sexos, se utilizó la prueba de U Mann-Whitney, junto a la g de Hedges para valorar el tamaño del efecto. Igualmente, se exploraron las posibles asociaciones existentes entre las dimensiones del cuestionario, la edad y los niveles de actividad física de los estudiantes. Los resultados mostraron diferencias significativas en las motivaciones para la actividad física entre hombres y mujeres, en los ítems de disfrute, apariencia, social, fitness y competencia, por consiguiente, la práctica de actividad física en la población universitaria parece ser una estrategia eficaz para mejorar la salud física y mental, adquiriendo vital importancia como factor protector frente a numerosos trastornos psicológicos y sociales. Las intervenciones que promueven la práctica de actividad física centrándose en las principales motivaciones del alumnado, pueden crear mayor adherencia a esta práctica y, por lo tanto, mejorar los hábitos saludables entre los estudiantes universitarios.

Published: February 2025

This study investigates how the job stress levels of physical education and sport teachers vary according to gender, age, educational status and job position. Within the scope of the research, the data obtained from 520 teachers were used and the job stress questionnaire was evaluated under four main subheadings. The results of Bartlett's test and Kaiser-Meyer-Olkin (KMO) coefficient for the suitability of the data for factor analysis showed that the data were quite suitable for factor analysis; while the workload sub-heading explained the highest variance with 26.7%, skill use explained 14.2%, decision freedom explained 12.03% and social support explained 11.6% of the total variance. In the analyses based on gender differences, it was determined that male teachers had higher levels of workload stress, while female teachers had higher levels of skill use, decision freedom and social support stress. In the analyses conducted between age groups, no significant differences were found in the sub-dimensions. Similar results were obtained in the analyses conducted according to education levels. In the analyses conducted according to job positions, it was determined that administrators did not differ from non-administrators in all dimensions. These results show that it is important to customise job stress management strategies according to gender, age and job positions. It is emphasised that general stress management strategies should be developed to cover all demographic groups.

El tratamiento y análisis de los datos se desarrolló a partir de una lógica inductiva de categorización. Los resultados muestran que los profesores de EF en el contexto rural enfrentan dificultades por la falta de infraestructura y materiales deportivos, lo que deja en evidencia la necesidad de mejorar estos aspectos para garantizar una educación equitativa. Otro de los elementos relevantes a destacar es que la evaluación en EF en entornos rurales va más allá de la medición técnica, integrando el progreso emocional y motivacional de los estudiantes. Se concluye que es necesario incorporar enfoques educativos que combinen el desarrollo académico, personal y social que promuevan un aprendizaje significativo y equitativo.

The inclusion of some specific strength training programs could be a key strategy to reinforce the injury prevention process. This study aimed to analyze the effects of a 12-week low-load resistance training program on injury incidence, burden, and physical fitness in semiprofessional youth soccer players. Twenty male players were randomly assigned to the experimental group (EG, n = 10 players), which performed a low-load resistance training program, or to the control group (CG, n = 10 players), which performed only their usual soccer training. Injury incidence and injury burden were registered during the intervention, as well as the physical fitness attributes: jumping, repeated sprint abilities (RSA), change of direction ability (CODA), linear sprints and isometric strength, at baseline and after the training program. A significant (p < 0.05) lower injury incidence was observed in EG (CG: 9.57 vs. EG: 0.00 injuries/1000 h of exposure) and a significant (p < 0.001) lower injury burden in the EG (CG: 317.83 vs. EG: 0.00 days of absence/1000 h of exposure). The ANCOVA model revealed significant between-group differences favoring the EG, showing significant higher improvements in all physical fitness attributes (p < 0.001–0.024). This study demonstrated the effectiveness of a low-load resistance training program in preventing injuries and improving physical condition in young soccer players.

In recent years, the role of perceived responsibility in classroom climates has gained attention due to its potential impact on students’ cognitive performance. This study examined how a Responsibility-Based educational framework influenced cognitive failures—such as forgetfulness, distractibility, and false triggering—among undergraduate students in Physical Education classes at a State University in the Philippines. A sample of 617 students was used, and multiple regression analysis was performed to explore the relationship between the perceived responsibility classroom climate shaped by students and instructors and various cognitive failures. The results revealed that overall cognitive failures were significantly influenced by the perceived responsible classroom climate generated by both students and instructors. Notably, the perceived responsibility classroom climate generated by students significantly influenced forgetfulness, while the climate generated by students and instructors directly affected false triggering. Although the overall classroom climate did not influence distractibility, an independent analysis showed that the perceived responsibility climate generated solely by instructors predicted distractibility. These findings suggested that fostering a culture of accountability and support in educational environments could enhance students’ organizational skills and stress management, ultimately reducing cognitive failures. This study presented a vital advancement to educational scholarship by emphasizing the intricate link between responsibility in classroom settings and cognitive outcomes, particularly in Physical Education environments. The implications of these findings for educational practices, along with the study’s recommendations and limitations, were discussed in detail.
Music as ergogenic aid: comparative analysis of music tempos on selected physical fitness components of untrained collegiate students
Authors: Masagca Ramon Carlo
Published: February 2025

The study aimed to investigate the effect of three different music tempos such as 44-77BPM, 78-120BPM, and 121-200BPM, on selected physical fitness components, which include flexibility, cardiovascular endurance, muscular endurance, muscular strength, reaction time, and agility. Specifically, it also compared the music tempos to each other based on their effectiveness as ergogenic aids on the said fitness components. The study includes 70 participants (male=47;female=23) who are untrained collegiate students through purposive sampling. Four groups were formed, assigned by different music tempos (No Music Group=17; 40-77BPM=18; 78-120BPM=18;121-200BPM=17). The pretest was conducted by administering the fitness test, which measures the physical fitness components of the participants. Before the post-test, participants listened to a playlist with a music tempo assigned to their group. After this, the post-test commenced. The data was analyzed using a paired T-test for within-group comparison and ANOVA for the group comparison. The No Music Group and the 44-77 BPM group did not demonstrate any notable enhancement in the physical fitness components. The 78-120BPM group showed a significant improvement in flexibility of the lower limbs (p=.03, t=2.44) and agility in changing direction (p=.00, t=4.76). Lastly, the 121-200BPM group demonstrated a significant increase in reaction time (p=.01,t=3.14) and agility in changing direction  (p=.00,t=3.39) . As for group comparison, cardiovascular endurance was different among groups, suggesting the 121-200BPM group to be superior compared to another group (p=.01, t=4.02). Music with a tempo of 44-77 BPM should be used as post-workout recovery, while 78-120 BPM was observed to enhance flexibility and agility. Music in the 121-200 BPM range shows potential for improving reaction time and agility. Cardiovascular endurance was superior in the 121-200 BPM music tempo. Future studies should focus on the role of slower tempos in recovery, further investigate flexibility and agility across various BPM ranges, and ensure reliable performance evaluations through replication.

Zeugodacus cucurbitae (Diptera: Tephritidae) is a major insect pest of horticultural crops, causing significant yield losses.The efficacy of Beauveria bassiana, a potential biocontrol agent, can be influenced by growth media composition. This study examined the effects of cricket and fruit fly flour on B. bassiana growth and pathogenicity against Z. cucurbitae. The methods added B. bassiana growth media with different concentrations (0%, 0.5%, 1%, and 1.5%) of cricket and fruit fly flour and assessing its pathogenicity against Z. cucurbitae at a spore density of 10⁶ and 10⁸ spores/mL. The results showed that 1% cricket flour combined with a spore density ofspores/mL resulted in the highest mortality rate (29.33%) and the fastest infection (2 days). The lowest average mortalities were found in treatments without flour addition which were 21.3%, 19.3%, and 19%, respectively. The longest time to cause infection was observed in 7 days. Infection symptoms are marked by the emergence of white fungal mycelia covering the cuticle, while infected adults exhibit deformed, wrinkled, and smaller wings. These findings highlight the potential of growth media optimization to enhance B. bassiana virulence, contributing to the development of more effective and sustainable biocontrol strategies against Z. cucurbitae.

Shallots have physiological and pharmacological effects on the human body and have been cultivated intensively using biocompost, which may be contaminated with heavy metals. Enrichment of arbuscular mycorrhizal (AM) fungi in biocompost and the addition of biological organic fertilizer (BOF) to reduce the absorption of heavy metals in shallot bulbs is the main objective of this research. The study used a Randomized Block Design with five treatments, namely: shallots cultivation method by indigenous farmers/control(B0); Dose of biocompost enriched with AM fungi 100kg plot-1(B1); 200kg plot-1(B2); 100kg plot-1+BOF(B3); 200kg plot-1+BOF(B4), has been carried out in Enrekang district, South Sulawesi by observing the components of heavy metal content in plant organs and the level of infection of AM fungi in plant roots. Results showed that a dose of biocompost enriched with AM fungi 200 kg plot-1, and 100kg plot-1+BOF could increase Cr, Cu, and Pb accumulation in roots and leaf, as well as reduce metal accumulation in shallot bulbs, with level AM fungi infection classified as very high. The novelty of this study is that organic fertilizer enriched with AM fungi can reduce the absorption of heavy metals that accumulate in shallot bulbs and is essential information for farmers.
