Published: February 2025

Antecedentes: En la presente investigación, nos remontamos a las décadas de los años 1990-2010, cuando el autor se involucró directamente por cuestiones laborales, con todos los actores del Valle de Virú, en lo referente a su agroexportación y problemática. Objetivo: Proponer un modelo predictivo estadísticamente confiable para estimar las agroexportaciones de la región La Libertad de los cuatro productos de mayor demanda y apoyar en la toma de decisiones al sector agro exportador. Método: Para la recolección de datos se utilizó la técnica del seguimiento de transacciones, recopilando la información de las agroexportaciones de paltas, espárragos, arándanos y alcachofas de los últimos doce años, es decir, desde el 2012 hasta el 2023 de las entidades formalmente acreditadas. Resultados: Dado que los valores de correlación en R (multiplicado por 100), nos arrojan los siguientes resultados: paltas 62% y alcachofas también con un 62% y que el valor propuesto en nuestra hipótesis central consigna “no menor del 60%”, esta debe ser aceptada para dichos productos, debiéndose rechazar para los espárragos y arándanos. Conclusiones: Dado que los valores de correlación en R (multiplicado por 100), nos arrojan los siguientes resultados: paltas 62% y alcachofas también con un 62% y que el valor propuesto en nuestra hipótesis central consigna “no menor del 60%”, esta debe ser aceptada para dichos productos, debiéndose rechazar para los espárragos y arándanos.

Broiler chicken is one of the major lean sources of protein. In many countries, its demand is rapidly increasing. Soybean and fishmeal are commonly used in poultry feed; however due to hype in price and decrease in production rate these feedstuffs become limited and scarce. Protein is one of the major component of poultry feed costs about 60%-70%. However due to high cost of protein, it becomes a challenging factor for farmers to supply enormous amount of protein in poultry feed. These challenging factors led to the discovery of an alternative rich source of animal based poultry feed with enormous amount of protein. Thus, this need led to the discovery an alternative source of protein for poultry that could be red worm (Eisenia fetida). The purpose of this study was the better growth and development yielded with high nutritional composition of red worms reared on cow manure and organic food waste and to introduce earthworm meal as an alternative protein source for Poultry. Red worms have a potential to be used as a protein supplement. Red worms are a good source of protein (58- 71% dry matter). In this case study, 390 red worms were reared on kitchen waste. For rearing of worms, cow manure mixed with soil (1:1) was used as a culture substrate. Cow manure was used because it has high amount of nitrogen which is more nutritious for growth and development of worms than any other culture substrate. The assay was conducted for about 3 months in winter season. Nutritional value of worms was analyzed after their rearing to determine their nutritional content. Proximate analysis was performed to determine the nutritional value of red worms. Kitchen waste was preferably used to overcome the waste pollution as well as it was a cheap and good source of organic matter.
Climate Change and Political Activism
Authors: Ali Muhammad 
Published: February 2025

Barack Obama, the former President of the United States, once stated, “We are the first generation to feel the impact of climate change and the last generation that can do something about it.” This statement thoroughly demonstrates the urgency of the climate change situation and its impact on the world. Glaciers are melting faster, losing 31% more snow and ice per year than they did 15 years earlier. As a result, low-lying areas throughout the world have increasingly experienced floods. This is only one of the many disasters and problems that climate change is posing, which only seem to increase with time. This highlights the necessity of climate political action, eyeing the dire consequences which seem to gradually tower over the globe, very rapidly. Zig Ziglar, a famous American author, aptly said, “The first step in solving a problem is to recognize that it does exist.”, and political activism serves that very purpose, to make people aware of the dire climate situation.

Published: February 2025

Emotional Intelligence (EI) is a psychological factor which can increase employee’s ability and performance. Highly Emotional Intelligence employees are able to produce good quality products and services at their work environment. There is dearth of information on EI and turnover intentions of employees in family owned business in Zimbabwe which this qualitative study sought to address. However, the purpose of this research is to analyse the relationship of EI and turnover intentions of employees in small businesses. Through purposive sampling 20 respondents were interviewed to solicit the information where data was analysed and presented thematically. Findings indicated that employees with high emotional intelligence may properly balance the relationship between work and family and reduce job burnout thus resulting in less turnover intention. The findings shows that emotional intelligence (EI) improves employee engagement and these improvements can lead to lower absenteeism, higher productivity, and a decrease in employee turnover. The study also has some theoretical implications regarding employees’ perception of emotional intelligence (EI). Further study need to be done on EI and leadership commitment in small businesses in Zimbabwe

The Effect of Foot-Ankle Condition On Physical Performance in Cerebral Palsy With Spastic Equinus Deformity
Authors: Uysal İsmail , Özden Fatih , Karaman Özgür Nadiye , İmerci Ahmet 
Published: February 2025

Abstract
Background: The severity of foot disability in children with cerebral palsy (CP) should be examined with both objective and subjective assessment tools. This cross-sectional study investigated the effect of foot-ankle function on physical performance in CP with spastic equinus deformity.
Methods: A cross-sectional prospective study was performed on 61 children with cerebral palsy. Participants were evaluated by Gross Motor Function Classification System (GMFCS), Oxford Ankle Foot Questionnaire for Children (OxAFQ-C), Timed Up and Go Test (TUG), Single Leg Stance Test (SLST), 3-Meter Backward Walking Test (3MBWT) and Functional Reach Test (FRT).
Results: The mean age of the children with CP (28 female, 33 male) included in the study was 11.3±4.4 years. Individuals with higher ankle-foot function had better TUG, 3MBWT, and SLST performances (p<0.005). OxAFQ-C physical scale was moderately correlated with TUG (r=−0.474) and SLST (right extremity-eyes open) (r=0.386) (p<0.01). In addition, there was a low significant correlation between 3MBWT, SLST (right extremity-eyes closed), SLST (left extremity-eyes open), and SLST (left extremity-eyes closed) with OxAFQ-C physical scale (p<0.05). OxAFQ-C school and play scale had a moderate to weak correlation coefficient (r=0.257-0.430) with all physical performance tests (p<0.05). In addition, there were moderate and low correlations between OxAFQ-C emotional scale with TUG (r=−0.495) and 3MBWT (r=−0.298), respectively.
Conclusion: The results showed that foot-ankle performance influenced physical performance on time-based physical tasks but not better performance-based physical conditions. It was concluded that foot-ankle condition was most strongly associated with sit-to-stand and walking performance.
Morphological Characteristics of the Intrinsic Foot Muscles in Individuals With Flat Foot: A Systematic Review and Meta-Analysis
Authors: Taş Serkan , Ekici Ece , Yüzbaşioğlu Ümit , Özdemir Asena Ayça 
Published: February 2025

Abstract
Background: The purpose of this meta-analysis was to discern the changes in morphological characteristics of the intrinsic foot muscles, including changes in the cross-sectional area (CSA) and thickness of the abductor hallucis (AbH), flexor hallucis brevis (FHB), flexor digitorum brevis (FDB), and abductor digiti minimi (AbDM) in individuals with flat foot (FF).
Methods: We conducted our literature search in the PubMed, Web of Science, and Scopus electronic databases. We included English-language case-control and cross-sectional studies comparing the morphological features of the intrinsic foot muscles in adults with and without FF. The methodological quality of the five studies that met the inclusion criteria was assessed with an adapted version of the Newcastle-Ottawa Scale for cross-sectional studies. The mean difference (MD) with corresponding 95% confidence intervals (CIs) was used to quantify the effects between adults with and without FF.
Results: The study included five studies, one of which was classified as high quality, while the remaining studies were classified as moderate quality. The CSA of the FHB (MD = −0.41, 95% CI = −0.61, −0.22; p < 0.001, I2:59%) and AbDM (MD = −0.21, 95% CI = −0.32, −0.11; p< 0.001; I2=1%) and the thickness of the AbDM (MD = −1.43, 95% CI = −1.81, −1.05; p< 0.001; I2=1%) were lower in individuals with FF than in the control group. However, the CSA of the AbH and FDB, and the thickness of the AbH, FHB, and FDB exhibited no significant differences between the FF and control groups.
Conclusion: The results of our study indicate that individuals with FF exhibited significant atrophy of the FHB and AbDM muscles. However, the morphology of the AbH and FDB muscles did not appear to influence foot posture, based on the five studies that were considered.

Published: February 2025

The shift in vertical forces on the equine hoof surface by heart-bar, egg-bar, and wooden clog shoes can significantly impact gait kinetics. Hypotheses tested in this study were that vertical, braking, and propulsion peak force (PF) and impulse (IMP) are different while shod with heart-bar, egg-bar, open-heel, and wooden clog shoes, or while unshod, and the resultant ground reaction force vector (GRFYZ) has the longest duration of cranial angulation with open-heel shoes followed by unshod, then egg-bar and heart-bar shoes, and the shortest with wooden clog shoes. Forelimb GRFs were recorded as six non-lame, light-breed horses walked across a force platform (four trials/side) while unshod or with egg-bar, heart-bar, open-heel, or wooden clog shoes. Outcomes included vertical, braking, and propulsive peak forces (PFV, PFB, PFP) and impulses (IMPV, IMPB, IMPP), percent stance time to each PF, braking to vertical PF ratio (PFB/PFV), walking speed (m s−1), total stance time (ST) and percent of stance in braking and propulsion. The magnitude and direction of the resultant GRFYZ vectors were quantified at 5% stance increments. Kinetic measures were compared among shoeing conditions with a mixed effects model (p-value < 0.05). A random forest classifier algorithm was used to predict shoeing condition from kinetic outcome measures. All results are reported as mean ± SEM. Trial speed, 1.51 ± 0.02 m s−1, was not different among shoeing conditions. The PFV was lower with wooden clog (6.13 ± 0.1 N kg−1) versus egg-bar (6.35 ± 0.1 N kg−1) shoes or unshod (6.32 ± 0.1 N kg−1); the PFP was higher with wooden clog (0.81 ± 0.03 N kg−1) versus open-heel (0.71 ± 0.03 N kg−1) or egg-bar (0.75 ± 0.03 N kg−1) shoes or unshod (0.74 ± 0.03 N kg−1), and lower with open-heel compared to heart-bar shoes (0.77 ± 0.03 N kg−1). Both IMP B and IMPV were higher with open-heel shoes (−0.19 ± 0.008 N s kg−1, 3.28 ± 0.09 N s kg−1) versus unshod (−0.17 ± 0.008 N s kg−1, 3.16 ± 0.09 N s kg−1), and IMPV was higher with wooden clog shoes (3.26 ± 0.09 N s kg−1) versus unshod. With wooden clog shoes, PFB/PFV (0.12 ± 0.004) was higher than unshod (0.11 ± 0.004). Percent time to peak PFV, PFB, and PFP, and percent braking time were highest and percent propulsion time lowest with wooden clog shoes. The magnitude of the GRFYZ vector with the wooden clog shoe was the highest among shoeing conditions during the first stance half, lowest during the second stance half, highest during late propulsion, and had the most gradual braking to propulsion transition. Vectors were angled cranially with wooden clog shoes slightly longer than the others. Wooden clog shoes was the only shoeing condition accurately predicted from kinetic measures. Distinct, predictable changes in gait kinetics with wooden clog shoes may reduce stresses on hoof structures. Study results enhance knowledge about shoe effects on equine gait kinetics and cutting-edge measures to quantify them.
Prediction of clinical deterioration within one year in chronic obstructive pulmonary disease using the systemic coagulation-inflammation index: a retrospective study employing multiple machine learning method
Authors: Hou Ling , Min Ming , Hou Rui , Tan Wei , Zhang Minghua , Liu Qianfei 
Published: February 2025

Background
Inflammatory response and the coagulation system are pivotal in the pathogenesis of clinical deterioration in chronic obstructive pulmonary disease (COPD), prompting us to hypothesize that the systemic coagulation-inflammation (SCI) index is associated with clinical deterioration in COPD.

Methods
A cohort of 957 COPD patients (mean age: 68.4 ± 7.8 years; 74.4% male) from January 2018 to December 2021 was analyzed. Six machine learning models (XGBoost, logistic regression, Random Forest, elastic net (ENT), support vector machine (SVM), and K-nearest neighbors (KNN)) were evaluated using accuracy, precision, recall, F1-score, and the area under the receiver operating characteristic curve (AUC-ROC).

Results
Our study encompassed 957 patients, out of which 171 were classified in the clinical deterioration of COPD (cd-COPD) cohort. Significant disparities in age, comorbidities like respiratory failure, C-reactive protein, lymphocyte count, red blood cell distribution width (RDW), SCI, procalcitonin (PCT), and D-dimer were depicted between the cd-COPD and non-cd-COPD groups. Concerning machine learning and model comparison, the SVM model showcased consistent performance and strong generalization capabilities on both the training and testing sets compared to the other five machine learning (ML) models. The SCI index, as the most influential predictor, demonstrated a median of 93.08 in cd-COPD compared to 81.67 in non-cd-COPD patients.

Conclusion
The SCI is markedly elevated in cd-COPD patients compared to COPD patients, and SVM demonstrates reliable performance in cd-COPD prediction.
Role of contrast-enhanced ultrasound with time-intensity curve analysis about thyroid nodule and parenchyma for differentiating BRAF V600E mutation status
Authors: Hu Zhipeng , Xue Rong , Liu Zhixi , Liu Liang , Gong Zheli 
Published: February 2025

Background
The BRAF V600E mutation was proven associated with papillary thyroid cancer (PTC) which has more aggressive behavior and could affect the outcome of PTC. The objective of this study was to observe more contrast-enhanced ultrasound (CEUS) time-intensity curve (TIC)—based quantitative parameters in nodules and surrounding parenchyma and analyze the association between the TIC-based quantitative parameters and BRAF V600E mutation status in patients with PTC.

Methods
A retrospective analysis of 447 PTC patients was conducted. Prior to thyroidectomy or fine needle aspiration (FNA), all patients had CEUS and had their BRAF V600E mutations examined. Based on their mutation status, the patients were split into two groups. The two groups were compared in terms of sex, age, quantitative CEUS characteristics, pathological findings, vascular invasion, capsular invasion, and cervical lymph node metastases.

Results
A total of 240 patients were in the mutation negative group and 207 patients were in the BRAF mutation positive group. The BRAF-positive group exhibited significantly higher arrival time (AT) and time to peak enhancement (TTP) of the nodules, among other direct quantitative characteristics. The BRAF-positive mutant nodules showed significantly higher arrival time change and time to peak change compared to the surrounding parenchyma for indirect quantitative metrics.

Conclusion
The time-dependent quantitative parameters of CEUS time intensity curve in nodules and surrounding parenchyma have clinical value in distinguishing BRAF V600E mutation positive nodules from gene mutation negative nodules. Quantitative CEUS characteristics may be beneficial in detecting the BRAF V600E mutation status and informing the subsequent clinical choice.
Comparison of fracture resistance between immediate and delayed composite restorations with or without fiber after root canal treatment: a field-emission-gun scanning electron microscope study
Authors: Kaynar Zeynep Buket , Akbal Dinçer Gözde , Donmez Nazmiye 
Published: February 2025

Background
This study aimed to evaluate the fracture resistance of immediate and delayed restorations after root canal treatment (RCT).

Methods
Sixty human intact premolar teeth were used. Teeth were prepared disto-occlusally. After RCT, teeth were randomly divided into two groups according to restoration times (immediate or 3 months delayed). The three month delay was imitated by thermomechanical aging. Then, samples were divided into six subgroups (n = 10). While I (Composite resin), II (Flowable bulk-fill) and III (Ribbond+Flowable bulk-fill) were restored immediately, Groups IV, V and VI were restored with temporary filling material and stored in distilled. After subjected to thermo-cycling (2,500 cycles, 5–55 °C) and exposed to 60,000 cycles in a chewing simulator, Group IV (Composite resin), V (Flowable bulk-fill) and VI (Ribbond+Flowable bulk-fill) were restored. All of the teeth were fractured on the universal testing machine. Failure modes were analyzed using scanning electron microscope. Data were analyzed using the Shapiro-Wilk and two-way ANOVA tests (p < 0.05).

Results
The highest fracture resistance was recorded in Group III while the lowest in Group VI. No statistically significant difference was observed among groups (p > 0.05). Most of the repairable fractures were seen in Groups I and II.

Conclusion
Delaying the permanent restorations of teeth for 3 months did not affect fracture resistance. However, it was suggested to avoid delaying restorations for obtaining repairable surfaces.
