Transformación productiva e inseguridad alimentaria en zonas de conflicto armado. El caso de María la Baja, Colombia
Authors: Arrieta Flórez Rosaura , Alvis-Arrieta Jorge , Espinosa- Espinosa Aarón 
Published: December 2023

El artículo analiza la transformación productiva en el marco del conflicto armado interno co­lombiano y sus efectos sobre las dinámicas económicas, sociales y ambientales de las poblaciones campesinas de María La Baja (Montes de María). Mediante un análisis cuantitativo se verifican las relaciones intertemporales entre las manifestaciones del conflicto y la expansión y concen­tración de cultivos de palma de aceite, en detrimento de la producción y acceso de alimentos. Así mismo, se documenta el papel de los actores armados en la fase previa de la expansión agroindustrial y su incidencia en el acceso a los alimentos. Se encontró que la expansión de la producción agroindustrial en María La Baja se correlaciona con hechos violentos del conflicto armado. El trabajo pone en valor las visiones territoriales que ayudan a comprender la natura­leza de las transformaciones productivas aupadas por políticas públicas agroempresariales que redujeron la autonomía y autosuficiencia alimentaria en comunidades campesinas.
Bounds and Heuristics for Multiproduct Pricing
Authors: Gallego Guillermo , Berbeglia Gerardo 
Published: December 2023

For a large class of demand models that allow for multiple consumer types, we present performance guarantees for simple nonpersonalized pricing heuristics relative to optimal personalized pricing. Our results demonstrate that in a general setting, the effectiveness of pricing along a positive vector depends on how the price vector aligns with optimal personalized price vectors. We propose two positive direction vectors: the “economic” and “robust” directions. The economic direction is a convex combination of the optimal personalized price vectors and aims to do well on average. The robust direction offers the best worst-case performance guarantee. By judiciously selecting pricing directions, our results also provide performance guarantees of simple pricing strategies relative to more sophisticated pricing strategies. In particular, we provide performance guarantees for nonpersonalized, optimal linear pricing relative to optimal nonlinear, personalized pricing. Our research also examines the performance of common heuristics for bundle pricing relative to optimal, personalized, bundle-size pricing. Our experiments show that performance often improves when consumer types are clustered and each cluster is offered a price direction. We compared the performance of the k-means clustering heuristic and the farthest point first clustering heuristic. Our findings indicated that k-means clustering has significantly superior performance on average. This suggests that businesses could potentially benefit from implementing k-means clustering in their pricing strategies. In conclusion, our study offers valuable insights and performance guarantees for various pricing strategies and their relative effectiveness. These findings could inform pricing decisions and potentially lead to improved outcomes for firms. This paper was accepted by Chung-Piaw Teo, optimization.

Local nurse-led outpatient follow-up pathway to identify and meet the needs of ostomates: a service evaluation
Authors: Ndlovu Simekuhle 
Published: December 2023

Background: In the changing face of healthcare, the number of nurse-led clinics has increased. This is also the case for stoma clinics in the UK. Although there is no standardised pathway, ostomates (person living with a stoma) in the UK are routinely followed up either by telephone or face-to-face depending on the need to deliver timely patient care. High-quality care and experience are important determinants of patient satisfaction in healthcare and align with the government's long-term plan, which expects this as standard. Therefore, this study explored the views and needs of ostomates to better understand the experiences and wishes of ostomates that attend a nurse-led clinic at a local hospital. Background/Aims: The aim of this study was to evaluate ostomates’ experience of care delivered on the stoma care nurse-led outpatient follow-up pathway. Methods: An adapted data collection tool was used to evaluate face-to-face and telephone clinics in a 3-month period (December-February). A non-probability convenience sample of 246 patients who accessed the pathway face to face (n=122) or by telephone (n=124) were surveyed. The questionnaires were sent to consenting respondents who had either a colostomy ileostomy or urostomy. Results: A total of 117 questionnaires were returned, with a response rate of 48%. The results showed that 98% of respondents on the face-to-face pathway said the nurse had answered all their questions compared to 80% on the telephone. Nine out of 10 (90%) of respondents were very satisfied with the overall telephone consultation, while only 68% of respondents were very satisfied with the overall face-to-face consultation. Almost all (97%) of ostomates from the face-to-face clinic were happy with the length of their appointment, compared with 81% of those from the telephone clinic. Overall, the respondents are generally happy with the service offered to them and they valued the role of the stoma nurses. Conclusions: The service evaluation highlighted several good areas of practice and identified areas that need improvement, including offering preference of type of clinics to ostomates. Both options of face-to-face and telephone consultations could be presented to ostomates to ensure appropriate quality of care. In addition, an action plan has been put in place to improve identified needs.

Published: December 2023

To make the driving force of a zoom cam cylinder stable and easy to control, the correlation between the cam curves of the zoom group and the compensation group is established effectively by reasonably selecting and arranging the coordinate system. Two optimization methods of cam curve are proposed. First, the original data are processed directly by the function of the target cam curve, and then the dynamic parameter such as the pressure angle is verified again to obtain the expected cam curve. This optimization method is simple and convenient, and a variety of optimization results can be constructed. Second, a physical model of multiple cam curves and the driving force with only one variable is constructed. The step search optimization method is used to process the original data point by point, and the best cam curve matching the model is obtained. Through dynamic simulation, it is determined that the cam curves designed by this optimization method can drive the zoom group and compensation group to complete the whole continuous zoom movement with a stable torque.
Factors affecting cervical cancer screening among Yemeni immigrant women in Klang Valley, Malaysia: A cross sectional study
Authors: Al-Oseely Sarah , Abdul Manaf Rosliza , Ismail Suriani 
Published: December 2023

Introduction
Cervical cancer is a significant public health problem for women worldwide. It is the fourth most frequent cancer in women globally. While early detection of cancerous lesions through screening tests leads to a better prognosis and a better chance of being cured, the number of people who go for screening is still low, especially for groups that are marginalized, like immigrant women.

Objective
The purpose of this study was to identify cervical cancer screening practices and factors influencing screening status among Yemeni immigrant women living in the Klang Valley, Malaysia.

Method
A cross-sectional study among 355 randomly selected respondents between the ages of 20 and 65 was conducted through an online survey. A questionnaire was sent directly to the participants via WhatsApp. The analysis was conducted using SPSS 25 with a significance level of 0.05. It included descriptive analysis, chi-square and multiple logistic regression.

Results
The response rate was 59%, with the majority of the respondents being married and between the ages of 35 and 49. Screening was reported at 23.1% in the previous three years. The final model revealed that age group 50–65 years (AOR = 5.39, 95% CI: 1.53–18.93), insurance status (AOR 2.22, 95% CI = 1.15–4.3), knowledge (AOR = 6.67, 95% CI = 3.45–12.9), access to health care facilities (AOR = 4.64, 95% CI = 1.29–16.65), and perceived barriers (AOR = 2.5, 95% CI = 1.3–4.83) were significant predictors of cervical screening uptake among Yemeni immigrant women in Malaysia (p<0.05).

Conclusion
According to the results, cervical cancer screening was found to be low among Yemeni immigrant women. The predictors were age group 50–65 years, insurance status, knowledge, access to health care facilities and perceived barriers. Efforts to enhance immigrant women’s participation in cervical cancer screening must tackle barriers to access to healthcare services as well as expand cervical cancer screening education programs.
Eccentric force and electromyogram comparison between the eccentric phase of the Nordic hamstring exercise and the razor hamstring curl
Authors: Murakami Yuta , Nishida Satoru , Kasahara Kaziki , Yoshida Riku , Hayakawa Ryo , Nakamura Masatoshi 
Published: December 2023

Purpose
Nordic hamstring exercise (NHE) and razor hamstring curl (RHC) are usually performed to train hamstring eccentric contraction strength. However, it is unclear whether there are differences in the intensity of the two methods and the amount of loading on each muscle. Therefore, this study was conducted using peak eccentric force and each muscle surface electromyogram (s-EMG) to provide useful information to decide whether NHE or RHC should be prescribed for training and rehabilitation.

Methods
s-EMG electrodes were placed in the medial gastrocnemius, lateral gastrocnemius, biceps femoris, semitendinosus, gluteus maximus, and erector spinae of the dominant leg of the fifteen healthy male university students with exercise habits. Maximum voluntary isometric contractions of 3 seconds were performed on each muscle followed by NHE and RHC in random order. The outcome variables included peak eccentric force and s-EMG of each muscle calculated by means amplitude during the NHE and RHC.

Results
Peak eccentric force was significantly higher in RHC than in NHE (p = 0.001, r = 0.73). However, NHE was significantly higher in s-EMG of semitendinosus (p = 0.04, r = −0.52) than RHC. However, there were no significant differences in EMG of the medial gastrocnemius (p = 0.202, r = −0.34), lateral gastrocnemius (p = 0.496, r = 0.18), biceps femoris (p = 0.061, r = −0.48), gluteus maximus (p = 0.112, r = −0.41), erector spinae (p = 0.45, r = 0.20) between NHE and RHC.

Conclusions
For NHE and RHC, the peak eccentric force exerted during the exercise was significantly higher for RHC, and the s-EMG of semitendinosus was significantly higher for NHE.

Authors: Crowther Daniel , Curran Janet , Somerville Mari , Sinclair Doug , Wozney Lori , MacPhee Shannon , Rose Annette Elliott , Boulos Leah , Caudrella Alexander 
Published: December 2023

Background
People who use alcohol and/or drugs (PWUAD) are at higher risk of infectious disease, experiencing stigma, and recurrent hospitalization. Further, they have a higher likelihood of death once hospitalized when compared to people who do not use drugs and/or alcohol. The use of harm reduction strategies within acute care settings has shown promise in alleviating some of the harms experienced by PWUAD. This review aimed to identify and synthesize evidence related to the implementation of harm reduction strategies in acute care settings.

Methods
A scoping review investigating harm reduction strategies implemented in acute care settings for PWUAD was conducted. A search strategy developed by a JBI-trained specialist was used to search five databases (Medline, Embase, CINAHL, PsychInfo and Scopus). Screening of titles, abstracts and full texts, and data extraction was done in duplicate by two independent reviewers. Discrepancies were resolved by consensus or with a third reviewer. Results were reported narratively and in tables. Both patients and healthcare decision makers contributing to the development of the protocol, article screening, synthesis and feedback of results, and the identification of gaps in the literature.

Findings
The database search identified 14,580 titles, with 59 studies included in this review. A variety of intervention modalities including pharmacological, decision support, safer consumption, early overdose detection and turning a blind eye were identified. Reported outcome measures related to safer use, managed use, and conditions of use. Reported barriers and enablers to implementation related to system and organizational factors, patient-provider communication, and patient and provider perspectives.

Conclusion
This review outlines the types of alcohol and/or drug harm reduction strategies, which have been evaluated and/or implemented in acute care settings, the type of outcome measures used in these evaluations and summarizes key barriers and enablers to implementation. This review has the potential to serve as a resource for future harm reduction evaluation and implementation efforts in the context of acute care settings.

Published: December 2023

This manuscript describes the rationale and design of a family-based, Hispanic sexual minority youth (HSMY) specific preventive intervention, Familias con Orgullo (Families with Pride). HSMY (N = 306) and their primary caregivers will be recruited in South Florida and be randomized to Familias con Orgullo or prevention as usual. The intervention will be delivered by trained study facilitators. Outcomes will be measured at baseline and 6-, 18-, and 30-months post-baseline. The goals of this study are to evaluate whether the Familias con Orgullo intervention, compared to community practice, is effective in reducing drug use and depressive symptoms through the improvement of parent support for the youth, parent acceptance, family functioning, youth stress, and sexual minority stress. Additionally, we will explore whether gender and baseline levels of parent support for the youth, parent acceptance, family functioning, youth stress, and sexual minority stress moderate intervention effects on the youth outcomes.

From geopolitics and regional identity to geopoetics and self-identification – a trajectory of conceptualization of Central Europe?
Authors: Tobiasz Aleksandra 
Published: December 2023

The article problematizes the discourse on Central Europe following a trajectory from the twentieth-century geopolitics and region-building projects founded on identity politics to the contemporary geopoetics and literary self-identifications shaped in relation to place and time. Emphasis is put on the second geopoetic, literary pole which is nourished by negative categories and is composed of particular articulations of being a Central European shaped in time of historical discontinuities and crises. Methodologically the paper is framed by the interdisciplinary sensory studies. The article addresses several contemporary writers’ self-identifications (Andrzej Stasiuk, Robert Makłowicz, Drago Jančar) founded on “autobiographical sites” which give insight into shared articulations of certain elements of Central European myth (problematic identity, spatial in-betweenness and feeling of transience, idealized Habsburg Monarchy). Furthermore, the instances of reconfiguration of this myth are presented by paying attention to the role of somatic experience shaping sensuous topographies of Central Europe which reconfigure the region's imagined spatial coordinates by replacing the horizontal dichotomy of the desired western culture and rejected eastern politics with the vertical paradigm of southern and northern vectors. Has Central Europe present in contemporary twenty-first century literary representations replaced the twentieth-century Cold-War West-East geopolitical in-betweenness with the geopoetic meridian points of reference?

Published: December 2023

Background: Personal care products (PCPs) can contain phthalates, parabens, and other endocrine-disrupting chemicals. However, information on perception of risks from PCP use and how use varies by race and ethnicity is limited.
Objective: We evaluated differences in PCP use and risk perception in a diverse sample of participants recruited from a U.S. college campus and online.
Methods: A self-administered questionnaire captured information on sociodemographic factors, PCP use trends, and perception of risk associated with PCPs. Pearson's Chi-square and Fisher’s exact tests were used to determine differences in PCP use and risk perception by race and ethnicity. Ordered logistic regressions were performed to measure associations between PCP use frequency across racial/ethnic categories.
Results: Participant (n=770) mean age was 22.8 years (SD ± 6.0). Daily use of make-up (eye = 29.3%; other=38.0%; all=33.7%) and skincare products (55%) was most frequently reported among Middle Eastern and North African (MENA) participants. Non-Hispanic Black (NHB) participants reported the highest daily use of hairstyling products (52%) and lotion (78%). Daily make-up use was more frequently reported among females (41%) than males (24.6%). Levels of agreement were similar across racial and ethnic groups, that PCP manufacturers should be required to list all ingredients (≥87%). There were significant associations between the frequency of use of some personal care products and racial/ethnic categories when the use frequencies of participants from other racial/ethnic categories were compared to the use frequency of NHW participants.
Conclusion: There were significant differences in daily use frequency, levels of trust, perception of safety, and health risks associated with PCPs by race and ethnicity, underscoring that there may be different sources of exposure to chemicals in PCPs by race and ethnicity.
Simultaneous different mechanisms for the efficient synthesis of β-enaminones: 12-tungstocobaltic acid-supported on nano silica as an electron transfer and Brønsted acid nano catalyst
Authors: Razlansari Mahtab , Kahrizi Masoud 
Published: December 2023

Abstract
In the present study, 12-tungestocobaltic acid, H5CoW12O40, was immobilized on nano silica from rice husk (CoW@NSiO2) to develop a novel, efficient, heterogeneous and recyclable nano catalyst for the synthesis of β-enaminones. It is apparent from acidity and cyclic voltammetric measurements that, the catalyst is electroactive and undergoes reversible redox transitions, as well as it is contains strong acid sites and mobile protons. As evidenced from mechanistic investigations, CoW@NSiO2 can catalyze the synthesis of β-enaminones with two simultaneous ways: electron transfer and Brønsted acid mechanisms. In order to confirm the synthesis of enaminones through simultaneous mechanisms of electron transfer and acidity, the model reaction was carried out in the presence of K5Co as an electroactive catalyst and CoW@NSiO2 with electron scavenger as an acid catalyst. The results showed that the reaction proceeded simultaneously through both mechanisms. There is evidence that the electron transfer property of this catalyst is most pronounced in this type of organic reactions. The catalyst demonstrated outstanding performance, and the methodology proved to be versatile, yielding excellent results across a wide range of substrates. It is worth mentioning that aliphatic amines were well-tolerated in the process and produced β-enaminone compounds with excellent yields and short reaction times. Also, reactions with dimedone, a cyclic 1,3-diketone, delivered moderate product yields. Additionally, the catalyst showed remarkable recyclability, maintaining its activity for a minimum of five consecutive cycles without any noticeable decline. Notably, the cyclic voltammetric and acidity measurements revealed that the catalyst’s electron transfer property and Brønsted acidity remained unchanged after five runs.

Authors: Branstetter Joshua W. , Mantione Jill , Deangelo Alyssa , Branstetter Lindsey A. 
Published: December 2023

CONTEXT
Gabapentin has shown benefits for a variety of pain etiologies in adult patients, with off-label use as an adjunctive agent in pediatric patients occurring more frequently.

OBJECTIVES
To summarize the studies which evaluate safety and efficacy of gabapentin for the treatment of pediatric pain.

DATA SOURCES
A systematic review of the literature was conducted via PubMed query with controlled vocabulary and key terms using indexed medical subject heading.

STUDY SELECTION
Prospective studies published between January 1, 2000, and July 1, 2023, were selected utilizing a predetermined exclusion criteria independently by 2 authors, with a third independent author available for discrepancies.

DATA EXTRACTION
Data extraction was performed by 2 authors independently to include study design, patient population and characteristics, drug dosing, and outcomes. Studies were then assessed for their independent risk of bias utilizing the Grading of Recommendations, Assessment, Development, and Evaluations approach to risk of bias.

RESULTS
A total of 11 studies describing 195 pediatric patients who received gabapentin were included. Of the 11 studies, 9 were randomized controlled trials, 1 was a prospective multicenter study, and 1 was an open-label pilot study.

CONCLUSIONS
Heterogeneity of pain type and gabapentin dosing regimens within the included studies made conclusions difficult to quantify. Efficacy likely depends significantly on etiology of pain; however, per these studies, gabapentin is likely safe to use for a variety of pediatric patient populations as a multimodal agent.
