Authors: Leal Fuentes Ingrid , Molina González Temístocles , Carstens Riveros Carolina
Published: October 2024

Objetivo Analizar variables de salud sexual y reproductiva de mujeres adolescentes y jóvenes migrantes y chilenas.
Métodos Estudio transversal, analítico de la Novena Encuesta Nacional de la Juventud. La muestra correspondió a 3 140 mujeres de 24 años y menos, extranjeras y chilenas. Se realizó un análisis descriptivo y de asociación mediante prueba Rao-Scott. La asociación se midió calculando Odds ratio. Se ajustaron modelos de regresión lineal múltiple y logística múltiple.
Resultados Las jóvenes migrantes correspondieron al 3,47%. En promedio llegan a Chile a una edad de 17,58 años. Estas jóvenes presentaron mayor porcentaje de convivencia (21,49% vs. 10,67%, p=0,002), hijos (45,28% vs. 23,69%, p=0,002), mayor edad para embarazo no planificado (18,92 años vs. 17,67 años, p=0,033) y primera pareja sexual esposo o conviviente (19,47% vs. 6,09%, p=0,017). La razón entre las jóvenes que no practican sexo anal versus las que sí lo practican, es 2,6 (1/0,38) veces mayor en extranjeras (OR: 0,38; IC 95%: 0,16–0,91). La razón entre jóvenes que usaron un anticonceptivo menos efectivo en la primera y en la última relación sexual versus aquellas que usaron uno efectivo o más efectivo, es 2,19 y 2,40 veces mayor en las jóvenes migrantes que en las chilenas (OR: 2,19; IC 95%:1,03-4,64 vs. OR: 2,40; IC 95%:1,16-4,97).
Conclusiones Las jóvenes extranjeras son un grupo pequeño de la población joven que vive en Chile. Existen similitudes entre jóvenes migrantes y chilenas para acceder a anticonceptivos y diferencias en el tipo de pareja y el estado civil al iniciar su actividad sexual, el número de hijos, las prácticas sexuales y el tipo de anticonceptivo usado.

Published: October 2024

Objetivo Se buscó identificar las experiencias de afrontamiento de la enfermedad en pacientes de los servicios de hospitalización en piso y la unidad de cuidados intensivos coronaria de una clínica en Ibagué (Tolima).
Métodos Con una aproximación cualitativa, se aplicaron dos instrumentos a 15 pacientes masculinos y femeninos, entre las edades de 25 y 78 años que vivenciaron diferentes patologías de carácter crónico.
Resultados Las experiencias de afrontamiento de los pacientes dan cuenta de la existencia de repertorios de acción y omisión en torno al afrontamiento y el cuidado de la enfermedad, así como prácticas de bienestar. Se explicitaron categorías acerca de las preocupaciones, lo difícil, lo bonito, lo que ayuda a llevar la enfermedad, lo que ayuda al bienestar y las proyecciones de deseo al superar la crisis de hospitalización.
Discusión La ruptura con las formas de vida es una de las principales dificultades que, sumado a la enfermedad, la incertidumbre y la calidad del servicio hospitalario genera condiciones favorables o no para el afrontamiento.
Conclusiones Poder identificar las estrategias de afrontamiento de los pacientes dentro del tiempo de hospitalización puede llegar a influir de manera positiva o negativa en su recuperación. Se hace relevante reconocer y dar lugar a los saberes y las prácticas desde la voz de los propios pacientes, para generar acciones coherentes y respetuosas con distintas formas de vivir, cuidar y morir.

Published: October 2024

Objetivo La tuberculosis, enfermedad curable y prevenible, es una de las diez primeras causas de morbimortalidad en la población mundial. Según los boletines epidemiológicos de la Alcaldía de Riohacha, se observa un aumento inexplicable de casos de la enfermedad en los últimos cinco años.
Métodos Este trabajo analiza los factores asociados a la incidencia de casos de tuberculosis desde el 2018 al 2022 notificados en el Sivigila. Fueron analizadas diferentes variables entre los años mediante la comparación de proporciones y en conjunto con un análisis de componentes principales usando la plataforma R.
Resultados La enfermedad se presentó con mayor frecuencia en hombres y en personas sin seguridad social. La distribución etárea fue la misma en los años evaluados; en relación con la pertenencia étnica, el 90% de los positivos fueron indígenas o migrantes. La ocupación fue la variable que mayormente explica la presentación de los casos; ama de casa y “no aplica” fueron las más importantes (48%). No hay diferencias en la forma de diagnóstico en los casos evaluados.
Conclusiones Se concluye que la migración y la falta de seguridad social contribuyen al aumento de los casos de tuberculosis observados. Es paradójico que siendo los hombres los más afectados, la ocupación con más frecuencia de presentación fue ama de casa.
About el2d2m on Line 4 of the E-45 Köžeelig-Xovu Inscription
Authors: Gulcali Zemire
Published: October 2024

For a more accurate interpretation of the Yenisei Inscriptions, Uyghur texts are as important a source of reference as the Khaganate Inscriptions. Especially in the analysis of words that do not appear in the inscriptions or are rare, the vocabulary of Uyghur can be a determining factor. For instance, in this article, I will focus on the word M𐌗Le el2d2m, which occurs in the E-45 Köžeelig-Xovu inscription but has been interpreted in different ways since its first publication. In order to read and interpret the word correctly, it will be reconsidered together with its examples in Old Uyghur texts.
Páciensspecifikus implantátumok használata arckoponya-rekonstrukció során
Authors: Csókay Gergely , Würsching Tamás , Szentpéteri Szófia , Nolden Elias-Leon , Vaszilkó Mihály , Bogdán Sándor
Published: October 2024

Az arckoponya-defektusok rekonstrukciója napjainkban is komoly kihívást jelentő
feladat. Ez a terület a komplex anatómiája és sokrétű, összetett funkciói
mellett esztétikailag is kiemelt szereppel bír. A helyreállítás során minden
esetben törekedni kell az anatómiai vagy azzal funckionálisan egyenértékű
rekonstrukcióra, illetve az arc harmóniájának visszaadására. A modern képalkotó
eszközök, tervezőszoftverek és 3D nyomtatók elterjedése következtében a
maxillofacialis traumatológiában használt hagyományos titán minilemezek és
-csavarok helyét egyre inkább átveszik a páciens egyedi viszonyaira digitálisan
tervezett és additív gyártási technológiával legyártott egyedi protézisek. 2010
és 2022 között összesen 11 alkalommal végeztünk arckoponya-, illetve
homlokcsont-rekonstrukciót páciensspecifikus implantátum segítségével. A
tervezési folyamatot, illetve a klinikai alkalmazás lehetőségeit 2 saját eseten
keresztül mutatjuk be. A beültetett implantátumok minden esetben
szövődménymentesen gyógyultak, sebgyógyulási zavar vagy kilökődés nem volt
tapasztalható. A rekonstrukció a virtuális tervnek megfelelő volt, jelentős
esztétikai javulást eredményezve. Eddigi tapasztalataink alapján a
páciensspecifikus implantátumok megbízható megoldást jelentenek a
maxillofacialis defektusok rekonstrukciójára Orv Hetil. 2024; 165(40):

A derékfájdalom kezelési lehetőségei: a betegoktatás jelentősége
Authors: Kupovits Tünde Rita
Published: October 2024

A derékfájdalom világszerte a leggyakoribb mozgásszervi probléma. Kutatások
szerint 2020-ban globálisan 619 millió embert érintett. A munkahelyről való
hiányzások és az orvoshoz fordulások nagy százalékáért felelős. 1990 óta több
mint 50%-kal nőtt a derékfájás okozta rokkantsággal eltöltött évek száma,
nagyrészt a világ népességének elöregedése és a népességszám emelkedése miatt. A
legnagyobb növekedés az alacsony és közepes jövedelmű országokban tapasztalható,
ahol nem feltétlenül állnak rendelkezésre megfelelő források a probléma
kezelésére. Ma már a derékfájdalom világszerte a rokkantság vezető oka. Akut
ellátásában fontos elkülöníteni a specifikus és a nem specifikus derékfájdalmat.
Általános prognózisa jó, azonban nagy a prevalenciája, ami miatt jelentős
népegészségügyi problémává válik. A krónikussá válás megelőzése kiemelten
fontos. Kezelésének célja a fájdalom csökkentése, a fizikai aktivitás
fenntartása és a munkaképesség mielőbbi visszaállítása. A rendelkezésre álló
evidenciákon alapuló terápiás módszerek és a klinikai gyakorlat között sokszor
széles a szakadék. Az ajánlások közé tartozik az önmenedzselés, a hétköznapi
tevékenységek újrakezdését támogató, oktatást és testmozgást is tartalmazó
programok, valamint a pszichológiai tanácsadás is. A mozgásprogramot és a
betegoktatást is tartalmazó kezelési módszerek a legeredményesebbek a krónikus
derékfájdalom kezelésében. Orv Hetil. 2024; 165(40): 1562–1569.
Az acromegalia kezelésének nehézségei 12 év próbálkozás tükrében
Authors: Gulyás Erna , Molnár Krisztián , Kajtár Béla , Radics Barbara , Dóczi Tamás , Mezősi Emese , Nemes Orsolya
Published: October 2024

Az acromegaliás betegek várható túlélése, életminősége rosszabb, mint az
egészséges populációé. Ennek hátterében a diagnózis késése és a műtét után is
sokszor megmaradó acromegalia-aktivitás áll. Így esetükben különösen fontos a
gyors, hatékony és egyénre szabott endokrinológiai kezelés és gondozás. 1965-ös
születésű nőbetegünket 2008 óta gondozták tenziós jellegű fejfájás miatt.
2012-ben sella-MR-vizsgálat 13 mm-es hypophysis-macroadenomát igazolt, melynek
teljes, transsphenoidalis műtéti eltávolítása megtörtént. A szövettani vizsgálat
somatrotrop adenomát mutatott. Posztoperatív orális glükóztolerancia-teszt során
biokémiailag aktív acromegaliát észleltünk negatív sella-MR-kép mellett, így
dopaminagonista kezelés indult, majd az inzulinszerű növekedési faktor-1
emelkedő szintje és fokozódó fejfájás miatt első generációs
szomatosztatinreceptorligand (SRL)-kezelésre tértünk át. Új keletű cukorbetegség
miatt a beteg biguanid-, majd izulinterápiát igényelt. Progrediáló panaszok
miatt növekedésihormonreceptor-antagonista kezelésre váltottunk, mely részleges
betegségkontrollt eredményezett, és nem változtak a páciens életminőségét
jelentősen rontó fejfájásos panaszok sem. Ezért egy évtizednyi terápiás
próbálkozás után a fennálló diabetes mellitus ellenére második generációs
SRL-kezelés mellett döntöttünk, mely a fejfájást azonnal megszüntette, és az
addig aktív acromegaliát kontrollálta. A szomatosztatin-receptor (SSTR)
altípusának utólagos vizsgálata domináns SSTR5-expressziót igazolt. Diabetes
mellitusszal szövődött acromegalia esetén is lehet optimális terápia a
pazireotid, amennyiben a daganat SSTR5-expressziót mutat. Orv Hetil. 2024;

Exploring interfacial tension role in the laminar morphology development in reactive compatibilized PP/EVOH
Authors: Staffa Lucas H. , Veroneze Isabelly B. , Cruz Sandra A.
Published: October 2024

Laminar-like structures in PP/EVOH (80/20 wt%) blends were developed by in situ reactive compatibilization using a co-rotating intermeshing twin-screw extrusion without the imposition of post-die-forming elongation flows, i.e., draw ratio (DR) = 0. For that, a maleic anhydride-grafted homopolymer polypropylene (PP-g-MA) was added at 1, 1.5, and 3 wt% using a simple mixing protocol. The correlation between the laminar morphology observed via SEM with interfacial parameters was conducted by nonlinear regression of PP/EVOH viscoelastic response (Gʹ and Gʹʹ) applying the Monomodal Palierne Model to estimate interfacial tension. Uncompatibilized PP/EVOH formed a droplet-matrix morphology with high interfacial tension, indicating incompatibility. As PP-g-MA is added, a laminar-like structure is developed. The remaining droplets become smaller at higher content, with lower interfacial tension between the phases. This scenario hampers the stratification of the dispersed phase. At 3 wt% of PP-g-MA, the morphology returns to being a droplet-matrix, although with high adhesion between the phases.

Fracture Injuries in Adult Korean Taekwondo Sparring Athletes
Authors: Song Munku , Yoo Sangcheul
Published: October 2024

PURPOSE: Fractures are common among Taekwondo-sparring athletes, yet little research has been conducted on these injuries in adult athletes. This study aimed to examine fracture injuries and post-fracture management practices in Taekwondo sparring athletes, with an emphasis on comparing lightweight and heavyweight classes.METHODS: Data were collected through interviews with 182 adult taekwondo sparring athletes in Korea (95 males and 85 females). The athletes were divided into lightweight and heavyweight groups based on the weight class in which they competed.RESULTS: Approximately 58.3% of the participants experienced taekwondo-related fractures, with heavyweight players having a significantly higher rate than lightweight players (χ²=3.987, p=.036). Overall, Taekwondo-related fractures occurred most frequently in the hand region during defensive maneuvers, and were caused by contact mechanisms. Fractures were more common among heavyweight athletes during competition and among lightweight athletes during training (χ²=6.395, p=.011). Heavyweight players were more likely to undergo surgery after fractures, whereas lightweights were more likely to receive conservative treatment (χ²=4.270, p=.039). Approximately half of the players (51.4%) returned to play after their fractures without a confirmed diagnosis of bone union, and the most common post-fracture psychological distress was fear of reinjury (57.2%).CONCLUSIONS: The current findings suggest that the fracture injury characteristics among elite Taekwondo-sparring athletes vary according to weight class, emphasizing the importance of injury prevention and management programs tailored to each specific weight class.

Authors: Choi Eun-hye , Han Mi-ock , Jun Hyung-pil
Published: October 2024

PURPOSE: To identify the characteristics of injuries among male collegiate athletes in combat and ball sports during the 2021 season and to propose strategies for injury prevention.METHODS: A total of 143 participants (67 combat and 76 ball sports athletes) registered with the Korean Sports & Olympic Committee in 2021 participated in this study. Each athlete responded to a questionnaire based on the injury survey developed by the International Olympic Committee. The questionnaire collected information on four demographic characteristics and three aspects of sports injuries: injury location, type, and cause. The Chi-squared test was used to compare injuries and determine the association between the two types of sports.RESULTS: The practice injuries and athlete exposures (AEs) recorded were 328 and 141,076 in combat sports and 384 and 142,054 in ball sports, respectively. The injury incidence rates (IRs) were 2.14/1,000 AEs (95% confidence interval [CI], 1.89-2.39) and 2.02/1,000 AEs (95% CI, 1.75-2.29) in combat and ball sports, respectively. Furthermore, the most common location, type, and cause of injury associated with both combat and ball sports were the ankles (combat: n=105, 34.8%; ball: n=60, 20.9%), sprain/ligamentous ruptures (combat: n=83, 26.4%; ball: n=96, 28.3%), and overtraining (combat: n=133, 41.7%; ball: n=94, 27.3%), respectively. Combat and ball sports were significantly associated in terms of injury location (Chi-squared =334.771, p<.001), type (Chi-squared=205.099, p<.001), and cause (Chi-squared=40.278, p<.05).CONCLUSIONS: Based on the results of this study, implementing an injury surveillance system is crucial for identifying risk factors and developing strategies to prevent injuries in both combat and ball sports. Additionally, coaches, supervisors, and trainers can incorporate specific exercise programs into their training regimens to strengthen anatomy frequently affected by injuries.

Authors: Lee Sang-Hwa , Park Saejong , Kim Kwangjun , Sung Joohon , Park Soo Hyun
Published: October 2024

PURPOSE: This study aimed to investigate the association between Sport-for-All (SFA) Condition and Healthcare utilization.METHODS: Using data from the National SFA survey (2019 and 2021) and the National Fitness Award100 (n=313) linked to the National health insurance sharing service, we examined associations between SFA condition and healthcare utilization.RESULTS: Hierarchical regression analysis indicated that demographic and health factors, individual-level factors, social and environmental factors of SFA participation, and physical fitness were associated with healthcare utilization. These factors uniquely explained 16.5%, 19.4%, 3.4%, and 0.2% of healthcare costs, and 11.5%, 11.8%, 8.5%, and 0.6% of healthcare services, respectively. Eight factors were associated with healthcare utilization. For healthcare costs, the significant factors were as follows: age (β=0.279, p<.05), chronic disease (β=0.396, p<.05), frequency of SFA (β=0.309, p<0.05), Intensity of exercise (β=-0.180, p<.05), self-related fitness (β=-0.291, p<.01), awareness of sports facilities (β=-0.178, p<.05), Experience with courses related to Sport-for-All (β=-0.195, p<.05), and certification of physical fitness (β=-0.117, p<.05). For healthcare service, the factors are as follow: age (β=0.349 p<.05), chronic disease (β=0.393, p<.05), frequency of SFA (β=0.302, p<.05), Intensity of exercise (β=-0.157, p<.05), self-related fitness (β= -0.286, p<.01), awareness of sports facilities (β=-0.194, p<.05), Experience with courses related to SFA (β=-0.153, p<.05), and certification of physical fitness (β=-0.134, p<.05). Additionally, participation in SFA exhibited a J-shaped pattern of healthcare utilization.CONCLUSIONS: We confirmed an association between SFA condition and healthcare utilization. Future studies should adopt a systematic, sports data-driven cohort approach to better understand and enhance the effectiveness of SFA participation.

Authors: Lee Mihyun , Lee Seunghee , Park Saejong
Published: October 2024

PURPOSE: This study aimed to assess the validity of a physical activity tracking device by comparing physical activity data from older adults, including the number of steps, energy expenditure, and heart rate (HR), with data obtained from research accelerometers, wearable watches, and mobile apps.METHODS: A total of 24 healthy older adults (aged 65-79 years) wore a wearable tracking device and used a respiratory gas analyzer while walking and running on a treadmill at speeds of 3.8 km/h, 4.8 km/h, 5.6 km/h, 6.4 km/h, and 8.0 km/h, in a randomized order. This study evaluated seven wearable devices: one research accelerometer (ActiGraph GT3X+), five smartwatches/fitness trackers (Samsung Galaxy Watch Active 2, Fitbit Versa 2, Xiaomi Mi Band 4, Garmin Forerunner 945, and Apple Watch Series 2), and one mobile application. Step counts were measured directly, HR was compared using a Polar H7 HR Sensor, and energy expenditure was assessed using a Quarkb2 respiratory gas analyzer.RESULTS: Commercial wearable watches and mobile applications were more accurate than research-grade accelerometers for monitoring steps during walking and running in older adults. HR measurements from wearable watches were more accurate than those from reference devices. Although energy expenditure measurements from mobile applications and wearable watches were less accurate than measurements of steps and HRs their accuracy was comparable to that of research-grade accelerometers.CONCLUSIONS: This study provides insights into the strengths of using wearable devices in healthcare and fitness fields, which seek to monitor and actively manage the physical activity of older adults using wearable trackers.
Analysis of the Moderating Effect of Walk Ratio on the Relationship Between Bone Mineral Density and Fall Efficacy and Balance Confidence in Elderly
Authors: Kim Min-Jun , Lee Inhwan
Published: October 2024

PURPOSE: This study aimed to analyze the moderating effect of the walk ratio (WR), a quantitative indicator of gait pattern, on the relationship between bone mineral density (BMD), fall efficacy scale (FES) score, and activity-specific balance confidence (ABC) in the elderly.METHODS: A total of 275 participants were categorized based on BMD into normal, osteopenia, and osteoporosis groups, and based on WR levels into high 25%, middle 50%, and low 25% groups. Logistic regression analysis was performed to determine the odds ratios (OR) for decreased FES and ABC exposure based on BMD and WR levels. To examine the moderating effect of WR on the relationship among BMD, FES, and ABC, a moderation analysis using Process Macro Model 1 was performed.RESULTS: After adjusting for age and sex, individuals with osteopenia (FES, OR=2.738, p=.013; ABC, OR=4.020, p=.002) and osteoporosis (FES, OR=4.550, p=.001; ABC, OR=5.015, p=.001) showed significantly higher ORs for decreased FES and ABC compared to those in the normal group, while individuals in the high WR group (FES, OR=0.389, p=.015; ABC, OR=0.235, p<.001) and middle WR group (FES, OR=0.519, p=.040; ABC, OR=0.389, p=.004) exhibited significantly lower ORs for decreased FES and ABC compared to those in the low WR group. Furthermore, moderation analysis indicated that regardless of covariates, the impact of decreased BMD on FES and ABC varied depending on the level of WR (FES, β=3.185, p=.017; ABC, β=4.570, p=.012).CONCLUSIONS: This study suggests that the decline in FES and ABC scores due to decreased BMD can be mitigated by a high WR. These findings highlight the need for strategies to enhance the walking function and prevent fractures in elderly patients with osteoporosis.
Impairment of Multi-Finger Force Control in Adult Patients with Dyskinetic Cerebral Palsy
Authors: Song Junkyung , Kim Kitae
Published: October 2024

PURPOSE: This study aimed to investigate the impact of cerebral palsy (CP) on motor control strategies, with a focus on understanding the altered capability of multi-finger force control in adult patients with dyskinetic CP.METHODS: Eight adults with dyskinetic CP and ten age- and sex-matched healthy controls participated in this study. The participants performed three force production tasks using four fingers of the dominant hand under isometric conditions: maximum voluntary contraction (MVC) to assess maximum force production, a ramp task to evaluate finger interdependency (enslaving), and a pulse task to examine the ability to rapidly and precisely adjust force. The co-contraction index (CCI) of finger flexor and extensor was also determined during steady state and pulse force production.RESULTS: Patients with dyskinetic CP demonstrated significant impairments in finger force control compared to healthy controls. Specifically, the accuracy and consistency of force production were reduced in the CP group, and they exhibited a longer time to peak pulse force. The CP group also showed increased finger interdependency and elevated CCI during pulse force production, suggesting a greater reliance on co-contraction and less efficient motor control strategies.CONCLUSIONS: This study highlights the distinct motor control deficits in individuals with dyskinetic CP, particularly in tasks requiring rapid and precise finger force adjustment. These results have important implications for the functional rehabilitation of patients with CP. Therapies aimed at reducing excessive co-contraction and decreasing finger interdependency may be beneficial for improving muscle coordination and overall motor function.
A Comparative Study of ALDH2 rs671 Gene and Physical Characteristics and Fitness of Sports Prodigies
Authors: Min Seok-Ki , Lee Kwang-Kyu
Published: October 2024

PURPOSE: This study aimed to identify differences in physique, basic physical fitness, and specific physical fitness based on the classification of the ALDH2 gene in sports prodigies.METHODS: This study tested the ALDH2 gene in 30 sports prodigies (18 males and 12 females). The participants’ physique (height, weight, arm and leg length, arm stretch, and thigh circumference), body composition (lean body mass and body fat), basic physical fitness (grip strength, sit-ups, sit-and-reach, T-wall test, light reaction time, and standing long jump), and specific physical fitness (shuttle run, sit and throw, sprint, and graded exercise test) were measured.RESULTS: There were no significant differences between the groups classified by gene type in terms of physique, body composition, or specific physical fitness (p>.05). However, in terms of basic physical fitness, only sit-ups showed a significant difference based on the gene classification (p<.05).CONCLUSIONS: The GG genotype group demonstrated superior physical fitness compared to the A allele group when tested for ALDH2. Therefore, ALDH2 gene testing is necessary for classifying physical fitness and designing personalized training programs.

ABSTRACT Objectives: to assess the association between indicators of emotional distress and dispositional mindfulness in health students at a Brazilian federal public university. Methods: a cross-sectional study, developed with university students in the health area of a public institution from May to June 2022. In the analysis, multiple linear regression was used using SPSS software. Results: the sample was mostly female, ≤ 22 years old, non-white, studying the first semesters, with a higher prevalence for the medicine course. Students presented moderate dispositional mindfulness scores. It was observed that the variables of stress, depression and current suicide risk were associated with the capacity for mindfulness. Conclusions: knowing the indicators of emotional distress that are related to the potential of mindfulness can contribute as a situational diagnosis to better design strategies that promote the improvement of emotional indicators of health students.

Abstract Objective: To explore the feasibility of two magnetic resonance imaging (MRI) sequences—high-resolution T2-weighted (HR T2) and Look-Locker T1 (LL T1) relaxometry—for the investigation focal lung lesions (FLLs). As a secondary objective, we analyzed the diagnostic accuracy of these sequences. Materials and Methods: This was a prospective observational study involving 39 subjects with FLLs scanned in a 1.5-T MRI system with LL T1 relaxometry and HR T2 sequences focused on the FLL region, in addition to a conventional protocol. All images were evaluated by two radiologists, working independently, who were blinded to other findings. Results: Most of the examinations (31 of the LL T1 relaxometry sequences and 36 of the HR T2 sequences) were of adequate diagnostic quality. Nondiagnostic examinations were considered so mainly because of limited coverage of the sequences. Of the FLLs studied, 19 were malignant, 17 were benign, and three were excluded from the accuracy analysis because there was no definitive diagnosis. Although LL T1 relaxometry could not distinguish between benign and malignant lesions, the signal intensity at its first inversion time (160 ms) differed between the two groups. The HR T2 sequence was considered the best sequence for assessing specific morphological characteristics, especially pseudocavities and pleural tags. We found that MRI showed better accuracy than did computed tomography (86% vs. 74%). Conclusion: Both MRI sequences are feasible for the evaluation of FLLs. Images at 160 ms of the LL T1 relaxometry sequence helped distinguish between benign and malignant lesions, and the HR T2 sequence was considered the best sequence for evaluating specific morphological characteristics.
Growing by decreascing
Authors: CECHIN ANDREI , VEIGA JOSÉ ELI DA
Published: October 2024

ABSTRACT To justify the thesis under the motto “growing by decreasing,” this paper presents three arguments. First, the evolution of ideas about tackling the environmental side effects of economic growth went from “limits to growth” to the unifying concept of “beyond-growth,” with “green growth” and “degrowth” as two poles of the recent debate. Second, there are indications of important convergences regarding policy prescriptions in any “green strategy.” Third, some clues suggest that, despite the convergences, the main challenge is overcoming the inertia in production-consumption systems by destabilizing the dominant configuration and inducing a change in consumers’ preferences.
Bridging the gap between production and ecology: a multi-regional input-output analysis of current Brazilian and Chinese productive and ecological relations
Authors: KLINK JAN , CARNEIRO GABRIEL SANTOS , FONSECA BRUNO CASTRO DIAS DA
Published: October 2024

ABSTRACT The arising literature on Ecological Unequal Exchange (EUE) incorporates multiple elements of post-Keynesian strands, in particular the structuralist analysis of global economic relations and the center-periphery divide. Nevertheless, there is still little discussion in the literature on the synergies and interconnections of the productive and ecological aspects of the peripheral condition. This work intends to enter this debate by proposing a multi-regional input-output (MRIO) analysis of the recent pattern of economic relations between Brazil and China, focusing on the evolution and linkages between the productive and the ecological aspects. The results show a rising unequal exchange of biophysical resources that flows from Brazil to China which is tied to key sectors of the recent Chinese catching-up process. In conclusion, it is argued that productive and ecological hierarchies entail two sides of the same coin of the peripheral condition.

Resumo A manufatura aditiva é uma tecnologia que permite a fabricação de peças através da adição sucessiva de material em camadas. Essa técnica permite a impressão de polímeros, metais, cerâmicas, biomateriais e materiais compósitos. Os materiais depositados podem ser arame, pó ou líquido. A Manufatura Aditiva por Deposição a Arco (MADA) é uma técnica promissora no processamento de ligas metálicas, onde, o Cold Metal Transfer (CMT) é uma variação do processo MIG/MAG que proporciona menor aporte térmico durante a transferência de material, influenciando na qualidade final da peça. Sendo assim, este trabalho tem como objetivo apresentar uma revisão bibliográfica das estratégias de deposições e comparar os efeitos causados ao se utilizarem diferentes parâmetros, especificamente pela MADA. Com isso, foi possível identificar que o controle do aporte térmico é um fator decisivo para evitar defeitos e melhorar o acabamento superficial das peças. Diferentes estratégias e parâmetros alteram a microestrutura e, como consequência, as propriedades mecânicas da peça.

ABSTRACT Objective: To evaluate the incidence of injuries to the infrapatellar branch of the saphenous nerve (IPBSN) after anterior cruciate ligament reconstruction (ACLR) with an oblique incision for hamstring graft harvesting. Methods: In total, 59 knees (from 57 patients) were evaluated in the follow-up of ACLR for six months. We drew a horizontal line parallel to the ground, passing through the most medial portion of the surgical incision and another, perpendicular to the first, starting at the tibial tuberosity (TT). We measured the length and angle of the cut, the distances from its most medial point to the perpendicular line, and from the TT to the horizontal line. Skin sensitivity was tested with a brush and the altered sensitivity area was measured. Patients were asked about difficulties in activities daily of living (ADL). Results: A total of 27 knees (45.7%) had sensory disorders, which persisted until the sixth postoperative month in 92.6% of them. The ADL were compromised in one knee (3.7%). No significant differences were found between the groups with and without changes in sensitivity regarding age, affected side, incision angle, or measured distances. The incision size was larger in the group without alteration in sensitivity. Conclusions: An oblique incision did not avoid IPBSN injuries. This condition rarely compromised the ADL.

ABSTRACT Objectives: Osteoarthritis (OA) is a degenerative disease associated with chondrocyte injury. This study investigated the dysregulation of microRNA-650 (miR-650) in cartilage tissues of patients with OA. Its function and mechanism were also investigated in OA cell models. Methods: miR-650 levels were examined in 15 OA cartilage tissues and ten healthy cartilage tissues. SW1353 cells were used for cell function experiments and IL-1β was applied to the cells to mimic OA conditions in vitro. Cell functions such as proliferation, apoptosis, and inflammation were detected. The downstream target gene of miR-650 was identified and confirmed by bioinformatic analysis and luciferase activity assay. Rescue experiments were performed to verify the mechanism. Results: Suppressed expression of miR-650 was tested in patients with OA and cell models. Overexpression of miR-650 increased cell proliferation but suppressed apoptosis and inflammation of SW1353. As the target gene of miR-650, WNT1 overexpression counteracted the role of miR-650 in the function of SW1353. Conclusion: miR-650 can protect against articular cartilage injury in OA by targeting WNT1. Level of Evidence I, Experimental Study.

ABSTRACT The COVID-19 pandemic has triggered a global crisis in health systems worldwide. Emergency care services have been overloaded, and there have been different changes in the patient’s profile and the most frequent diagnoses. The aim of the study was to compare the number of emergency surgeries in the Hand and Microsurgery group of the quaternary hospital (IOT-FMUSP) from March 2020 to February 2022, the pandemic period, with the previous two years, March 2018 to February 2020. Two hundred and seventy-two patients were evaluated, with a mean age of 39.54 ± 17 years (range 1 to 90 years), 12.50% (n = 34) women and 87.50% (n = 238) men. Between March 2018 and February 2020, 142 (52.21%) emergency upper limb surgeries were performed; between March 2020 and February 2022, 130 surgeries were performed (47.79%). There was a reduction in upper limb surgeries in patients between 26–45 years and blunt injury surgeries. There was also an increase in surgeries in patients over 46, amputations, fractures, re-implantation procedures, and open fracture fixation. Level of evidence III, Retrospective Comparative Study.

ABSTRACT Flexible intramedullary nailing and external fixation have become the main methods to surgically treat femur fractures in children. This study aimed to search the current literature and evaluate the clinical and radiographic results of surgical treatment by comparing these methods and investigating their associated complications. This systematic review was carried out following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) recommendations. Searches were carried out on the PubMed, Embase, and Web of Science databases. The search for journals in these databases was carried out from January 2023 to August 2023, retrieving 695 studies. This systematic review included 11 articles, which encompassed 718 patients who underwent surgical external fixation and flexible nailing. The most frequently observed complications referred to late or malunion, superficial and deep infections, skin irritation, angular deformity, and length discrepancy between lower limbs. Both methods of stabilization of pediatric femoral fractures can provide good clinical and radiographic results. However, the choice of treatment with flexible nails is certainly more valid and has greater acceptance than external fixation. Level of Evidence III, Systematic Review .

ABSTRACT Objectives: Evaluate the prevalence of hospital mortality in older adult patients with femoral fracture undergoing surgical treatment during the COVID-19 pandemic period, and to evaluate whether COVID-19 infection, clinical, and orthopedic factors interfered with mortality. Material and Methods: A retrospective study was conducted by reviewing medical records. Patients over 60 years of age with proximal femoral fracture undergoing surgical treatment were included. Overall mortality was calculated, as well as mortality whose primary or secondary cause was COVID-19 infection, to determine if infection influenced patient mortality. Clinical and orthopedic factors that interfered with mortality were evaluated. Categorical variables were compared using the Chi-square test or Fisher’s exact test. Both unpaired t-test (parametric variables) and Mann-Whitney test (non-parametric variables) were used. The Kaplan-Meier mortality curve was constructed. Conclusion: The mortality of older adult patients with femoral fracture undergoing surgical treatment during the COVID-19 pandemic was 4.2%. Male sex, older age, and those who underwent blood transfusion had higher mortality rates. COVID-infected patients had ten times more chance of death and died twice as fast as the non-infected population. Level of Evidence II, Retrospective Study.

ABSTRACT Objective: To evaluate the pregabalin adjuvant effect in patients with carpal tunnel syndrome (CTS) surgically treated, analyzing postoperative pain and the incidence of complex regional pain syndrome (CRPS). Methods: Outpatient surgical candidates with CTS were selected and followed for 12 months, divided into three groups. The Control Group received a placebo, the Pregabalin 75mg Group received a daily dose, and the Pregabalin 150mg Group received a daily dose of the medication. Patient progress was evaluated using the visual analog scale (VAS) for pain and the DN4 neuropathic pain score before surgery, one month and three months after. Results: The administration of pregabalin to surgical patients with CTS did not demonstrate significant differences in immediate postoperative pain relief. Additionally, there were no statistically significant variations in the incidence of complications, such as CRPS, among the groups. Conclusion: This study did not show a significant impact of pregabalin on postoperative pain relief or the reduction of CRPS incidence in patients undergoing surgery for CTS. These results suggest that pregabalin might not be an effective adjuvant in these surgical situations. Level of evidence II (Oxford), Prospective Comparative Study.

Resumo Introdução: Alterações fisiológicas do envelhecimento contribuem para osteoporose e fraturas relacionadas à baixa concentração sérica de 25(OH)D. Objetivo: Investigar a associação entre concentração sérica de 25(OH)D, ingestão de alimentos fonte de vitamina D e cálcio, condições de saúde e presença de osteoporose e fraturas em idosos. Método: Estudo transversal com 274 idosos do Piauí. Realizado em duas etapas: questionário sobre ingestão de alimentos fonte de vitamina D, cálcio e condições de saúde (incluindo a variável desfecho, presença de osteoporose e fraturas) e coleta de sangue para exame bioquímico de concentração sérica de 25(OH)D. Realizou-se análise descritiva, inferencial e regressão logística. Resultados: A maioria dos idosos apresentava comorbidades (86,4%). A prevalência dos desfechos foi de 23,7% e 14,6%, respectivamente. Na análise múltipla, ingerir bebidas alcoólicas (OR=6,58; IC95% 1,88–23) e reposição com cálcio (OR=2,87; IC95% 1,25–6,61) mostraram-se associados às fraturas, enquanto sexo feminino (OR=5,69; IC95% 1,12–28,9) e reposição com cálcio (OR=5,62; IC95% 1,62–19,5) mostraram-se associados à osteoporose. As maiores medianas de 25(OH)D foram encontradas naqueles que consumiam queijo e iogurte regularmente (p=0,021). Conclusão: A análise das concentrações séricas de 25(OH)D apontou insuficiência, indicando a necessidade de intervenções para a mudança do estilo de vida.

Resumo Introdução: As desigualdades sociais afetam historicamente as condições de vida e saúde das populações, e o padrão alimentar associa-se à situação socioeconômica dos indivíduos. Objetivo: Avaliar a magnitude das desigualdades sociais em indicadores de qualidade alimentar na população de Campinas-SP. Método: Estudo transversal, de base populacional, com 1.710 adultos e idosos entrevistados em 2014/15. Foram estimadas as prevalências e as razões de prevalência do consumo de alimentos avaliado por um questionário de frequência alimentar; além disso, foram verificadas as disparidades sociais segundo sexo, idade, escolaridade, renda e posse de plano de saúde. Resultados: Maior frequência de consumo de alimentos saudáveis foi verificada nas mulheres, nos idosos, nos estratos de maior nível de escolaridade e renda e no segmento social com plano de saúde. Por outro lado, paradoxalmente, os grupos sociais mais favorecidos não apresentaram menor consumo de refrigerantes, sucos artificiais, embutidos e biscoitos e bolachas nem apresentaram consumo maior de alimentos não saudáveis. Os idosos apresentam qualidade alimentar superior a todos os segmentos estudados. O segmento sem plano de saúde (usuários do SUS) teve pior perfil de consumo de alimentos, exceto para feijão e fast food. Conclusão: Expressivas desigualdades sociodemográficas foram detectadas, e os perfis combinaram o consumo de alimentos saudáveis e não saudáveis.

Abstract Yerba mate (Ilex paraguariensis) represents a culture of economic, social, and ecological importance for the cultivation regions. Due to the chemical, physical, and biological variations that occur in the different soils where yerba mate is economically exploited, the symbiotic associations with arbuscular mycorrhizal fungi (AMF) guarantee the plant's ability to absorb nutrients. The purpose of this study was to identify and quantify the occurrence of arbuscular mycorrhizal fungi in different environments of yerba mate cultivation. The research was performed in four areas located in the rural area of the municipality of Seberi/RS: Environment with production of yerba mate in the conventional system, silvopastoral system, organic system, and native forest. The normality of residuals and homogeneity of variances assumptions were verified using the Lilliefors and Chi-square tests and the averages compared by the Tukey's test at 5% probability of error. In addition to calculations of diversity, equivalent species, and evenness indices. The presence of AMF spores showed a direct relationship with the phosphorus (P) availability in each treatment, with a count reduction in the organic system, with P content lower than 3 mg kg-1 of soil. The species with the highest predominance were the Acaulosporaceae (Acaulospora colombiana, A. delicata, and A. tuberculata), followed by the Glomaceae (Glomus ambisporum and Glomus pansihalos) in the conventional and silvopastoral systems. The silvopastoral and conventional systems showed the highest levels of Shannon-Weaver diversity (H') and Pielou's evenness, demonstrating greater diversity and consequently greater richness and uniformity.
