El objetivo fue diseñar un programa para mejorar la condición física y evaluar su efecto sobre la intencionalidad de seguir siendo activo y autoestima general. Se diseñó un programa de 8 semanas de actividades para mejorar la condición física en Educación Física, además de actividad física deportiva en los recreos. El diseño cuasiexperimental incluyó 70 escolares (39 grupo experimental; 31 grupo control) de 6º de Educación Primaria. Como instrumentos de medida se utilizaron la batería ALPHA-Fitness de alta prioridad, la Escala de intencionalidad de ser físicamente activo en Educación Primaria, y el Cuestionario Multimedia y Multilingüe de Evaluación de la Autoestima. Se encontró efectividad del programa en todas las variables estudiadas, en especial en la mejora de la capacidad cardiorrespiratoria, la capacidad de salto y la dimensión socioafectiva de la autoestima. Se destaca la importancia de estos programas en la mejora de la salud física, psicológica y social del alumnado.
The objective was to design a program to improve physical fitness and evaluate its effect on the intent to remain active and general self-esteem. An 8-week program of activities was designed to improve physical fitness in Physical Education, in addition to sports physical activity at recess. The quasi-experimental design included 70 schoolchildren (39 experimental group; 31 control group) from 6th grade of Primary Education. The high priority ALPHA-Fitness battery, the intentionality scale of being physically active in Primary Education, and the Multimedia and Multilingual Self-esteem Evaluation Questionnaire were used as measuring instruments. The effectiveness of the program was found in all the variables studied, especially in the improvement of cardiorespiratory capacity, jumping capacity and the socio-affective dimension of self-esteem. The importance of these programs in the improvement of the physical, psychological and social health of the students is highlighted.
Editorial: Collective entanglements in the doing of research

Published: January 2021

In this final issue of RERM in 2020, no less than 20 authors have participated in the materialization of four articles, which connect to each other in various ways. All of the articles focus upon productive relations, between authors, as well as between materials and people.
All four articles illustrate the productiveness of moments in doing research that challenge the distinctions between researcher and researched, the concrete and the abstract, and the author and the text, arguably contrasting and adding humbleness to dominant academic structures centering the “researcher I” and its individual quest for qualifications.
The reliability and validity of the weight-bearing lunge test in a Congenital Talipes Equinovarus population (CTEV)
Authors: Gosse Georgia , Ward Emily , McIntyre Auburn , Banwell Helen A. 
Published: January 2021

Question
What is the intra and inter-rater reliability and concurrent validity of the weight-bearing lunge test within a Congenital Talipes Equinovarus population?

Design
Test retest design for reliability and validity. The measure was taken, following preconditioning of the participants, using distance from wall, angle at distal posterior tibia using a digital inclinometer and the iPhone level function, twice by each rater. The raters included a clinician, clinician in training and a parent/carer.

Outcome measures
Weight bearing lunge test as a measure of ankle dorsiflexion.

Results
Twelve children aged 5–10 years were eligible to participate and consented, along with their parents. Intra-reliability of distance measures for all raters were good to excellent (ICC clinician 0.95, ICC training clinician 0.98 and ICC parent 0.89). Intra-rater reliability of the iPhone for all raters was good (ICCs > 0.751) and good to excellent for the inclinometer (ICC clinician 0.87, ICC training clinician 0.90). Concurrent validity between the clinician’s and parents distance measure was also high with ICC of 0.899. Inter-rater reliability was excellent for distance measure (ICC = 0.948), good for the inclinometer (ICC = 0.801) and moderate for the iPhone (ICC = 0.68). Standard error of measurement ranged from 0.70–2.05, whilst the minimal detectable change ranged from 1.90–5.70.

Conclusion
The use of the WBLT within this CTEV population has demonstrated good to excellent reliability and validity amongst clinicians, clinicians in training and parents/carers, supporting its use as an assessment measure of dorsiflexion range of motion. There is support for parents/carers to use the WBLT at home as a monitoring assessment measure which may assist with early detection of a relapse.

Lead transfer in the soil-root-plant system in a highly contaminated Andean area
Authors: Castro-Bedriñana Jorge , Chirinos-Peinado Doris , Garcia-Olarte Edgar , Quispe-Ramos Rolando 
Published: January 2021

Lead (Pb) is highly toxic heavy metal that is detrimental to the food system. There are large mining and metallurgical companies in the central highlands of Peru that have been active for almost a century and contribute to air, water, and soil pollution, affecting food quality and causing damage to the environment and human health. Our study, conducted in 2018, assessed the content and transfer of lead in the soil-root-plant system in the high Andean grasslands in a geographical area near the metallurgical complex of La Oroya. Lead levels were measured in 120 samples of top soil (0–20 cm), roots, and grass shoots by flame atomic absorption spectroscopy. No significant differences were found between the soil pH, organic matter content, and lead among the samples evaluated (P > 0.05). Mean Pb concentrations decreased in the order of soil > root > shoot (P < 0.01) (212.36 ± 38.40, 154.65 ± 52.85 and 19.71 ± 2.81 mg/kg, respectively). The soil-to-root Pb bioconcentration factor, root-to-shoot translocation factor, and soil-to-shoot bioaccumulation factor values were 0.74 ± 0.26, 0.14 ± 0.06 and 0.10 ± 0.03, respectively. Lead in the soil was 3.03 times higher than the maximum limit for agricultural soil, and was 1.97 times higher than the value limit for fodder. Our findings are important and show that soils and pasture in this geographical area have high Pb levels due to metallurgical emissions that have been occurring since 1922. Such pollution negatively impacts health and the socio-economic status of the exposed populations.
A randomized, double-blind study of alpidem vs placebo in the prevention and treatment of benzodiazepine withdrawal syndrome

Published: July 2002

SummaryThe aim of the trial was to assess alpidem efficacy in preventing and treating the benzodiazepine (BZ) withdrawal syndrome (WS). A multicentre, double-blind, randomized versus placebo, parallel group study of six-week duration was carried out in outpatients suffering from generalized anxiety or adjustment disorder with an anxious mood and taking non-hypnotic BZ as continuous course of therapy of at least one-year duration. At the entry, the patients abruptly discontinued BZs and were treated with 50 mg/bid/tid of alpidem or placebo. Withdrawal syndrome diagnosis was (regarding treatment allocation) formulated by an independent psychiatrist, according to DSM-III-R and an appropriate scale, the SESSB. One hundred seventy-three patients were randomized and 148 completed the study. Withdrawal syndrome occurred in 27 patients of the alpidem group (31.0%) and in 38 patients of the placebo group (44.2%). A severe WS was diagnosed in 11.1% of the patients in the alpidem group and in 31.6% of the placebo group. If not having been withdrawn from the market, alpidem could have been useful for the prevention of BZ withdrawal syndrome.
Speculoscopy vs. the acetic acid test for cervical neoplasia
Authors: Cronjé H.S , van Rensburg E , Cooreman B.F , Niemand I , Beyer E 
Published: July 2002

AbstractObjective: To compare the specificity of speculoscopy and the acetic acid test (AAT). Methods: A randomized controlled trial was performed on 1150 women in a primary healthcare clinic. The main end‐points were the sensitivity and specificity of speculoscopy and the AAT. Results: The mean age of the patients was 37.7 years in the speculoscopy group (n=545) and 37.5 years in the AAT group (n=605). Cervicography (the golden standard) was positive in 11.3% of the participants, speculoscopy in 20.4% and the AAT in 25.1%. The sensitivity, specificity and the kappa value for speculoscopy were 53.5%, 83.6% and 0.23, respectively. For the AAT, the corresponding figures were 51.1%, 77.3% and 0.15. No statistically significant differences were found between these two groups. Of clinical importance, however, was a finding that speculoscopy did not miss a single case of high grade squamous intra‐epithelial lesion or cancer whilst the AAT missed five such lesions. Conclusion: Speculoscopy could not be shown to have an improved specificity when compared with the acetic acid test. The low specificity of both the tests will result in the referral of too many patients for colposcopy.
Women's health problems in the Arab World: a holistic policy perspective
Authors: Zurayk H. , Sholkamy H. , Younis N. , Khattab H. 
Published: July 2002

AbstractThe paper reviews key health problems of women in the Arab World. It relies on data and information from international yearbooks, regional data bases, and small scale field studies. The relevant context in which women live; of lingering illiteracy rates, lack of access to cash income, and increasing poverty is described. Reproductive health is reviewed within this context pointing to trends of delayed marriage and declining fertility in some countries while other countries maintain high levels. Similar variability is observed in contraceptive use rates and the interaction of contraception and health is discussed. Evidence points to high levels of reproductive morbidity. The socio‐cultural context is found particularly relevant to pregnancy and childbirth, seen as natural processes by women, to experiences of menopause, and to violence against women, particularly female circumcision. A holistic policy perspective is suggested to address these problems.
Ultrasound‐guided aspiration in management of cystic lesions of the ovary
Authors: Mittal S , Kumar S , Verma A 
Published: July 2002

AbstractObjective: To evaluate the role of ultrasound‐guided aspiration (UGA) as an alternative therapeutic modality in patients with cystic lesions of ovary (CLO). Methods: Forty‐six patients (age 14–65 years) of CLO were managed by UGA. Patients suspected of having malignancy either clinically or on ultrasound were excluded. The aspiration was done transvaginally (11 patients) or transabdominally (35 patients). All aspirates were subjected to cytological examination. Patients have been followed up for 10–48 months. Results: The cyst size varied from 4 to 30 cm and the volume aspirated ranged from 30 to 1600 ml. There were no procedure‐related complications. No further intervention were required in 33 (71.7%) patients. Re‐aspiration was required in six (13%) and, to date, seven patients (15.3%) have been operated on for recurrence or persistence of lesion. Recurrence rate was not influenced by cyst size or volume aspirated. Mucinous or hemorrhagic aspirate correlated significantly with a higher risk of recurrence. Conclusion: Ultrasound‐guided aspiration is a simple, safe and effective alternative to surgery in management of selected patients with CLO. Simple unilocular cysts can be safely aspirated, but it should not be carried out in patients with multilocular cysts. If the aspirate is hemorrhagic or mucinous, the patient should be considered for surgical intervention.

An investigation of the relationship between global manufacturing practices and outcomes in machine tools and textile industries
Authors: Kadipasaoglu Sukran N , Hurley Simon F , Foote Jeffrey L , Khumawala Basheer M 
Published: July 2002

AbstractThis empirical research study investigates the manufacturing planning and control (MPC) practices associated with successful company performance. To form a database of global manufacturing practices, data collected from machine tools and textile industries in 12 countries around the world via the Global Manufacturing Research Survey was combined. An exploratory factor analysis was first conducted to reduce the dimensionality of the data. Three Discriminant Analyses were then performed on the factor scores of successful and non‐successful companies, between free and planned economies and among the 12 countries represented in the database, with an emphasis on the factors found to be associated with success. The results show that close coordination of several business functions with the MPC system is essential for success. Significant differences were found between state‐managed and free‐market economies and among the countries represented in the database. In general, countries with free‐market economies had high success coefficients, led by Japan, which had the most combined use of essential success factors, while countries with planned economies had low success coefficients.
Fibroblast expression of C—C chemokines in response to orthopaedic biomaterial particle challenge in vitro
Authors: Yaszay Burt , Trindade Michael C. D. , Lind Martin , Goodman Stuart B. , Smith R. Lane 
Published: July 2002

AbstractC—C chemokines are soluble mediators that occur in a periprosthetic granuloma and influence recruitment, localization and activation of inflammatory cells. This study tested effects of titanium and polymethylmethacrylate (PMMA) particles on expression of selected C—C chemokines in cultured human fibroblasts. The C—C chemokines analyzed included monocyte chemoattractant protein‐1, 2 (MCP‐1, 2), monocyte inflammatory protein‐1 alpha (MIP‐1 alpha), and regulated on activation, normal T‐cell expressed and secreted protein (RANTES). Interleukin‐1 beta (IL‐1 beta) served as a known stimulator of chemokine release while interleukin‐6 (IL‐6) expression served as a marker for fibroblast activation. Protein and mRNA signal levels were determined by ELISA and RT‐PCR, respectively. The results demonstrated that exposure of fibroblasts to titanium and PMMA particles resulted in increased release of MCP‐1 in a dose‐ and time‐dependent manner. After 24 h, titanium particles maximally upregulated MCP‐1 release 7‐fold while PMMA particles increased MCP‐1 levels 2‐fold, when compared to unchallenged fibroblasts. MCP‐2, MIP‐1 alpha and RANTES levels remained unchanged following exposure of fibroblasts to titanium or PMMA particles at any concentration or time point tested. However, IL‐1 beta stimulated release of MCP‐1, MCP‐2, and RANTES, but not MIP‐1 alpha from the fibroblasts. IL‐1 beta, not particles, exhibited the most prominent effect on MCP‐1 mRNA levels. Increased release of MCP‐1 from fibroblasts exposed to titanium and PMMA particles coincided with increased release of IL‐6. This study suggests that release of chemoattractant factors from fibroblasts localized in periprosthetic membranes enhances the chronic inflammatory process leading to bone resorption and implant loosening. © 2001 Orthopaedic Research Society.

Expressed emotion in an 8 year follow-up
Authors: Schulze Mönking H , Hornung WP , Stricker K , Buchkremer G 
Published: July 2002

SummaryThis study addresses the questions if and for which patients expressed emotion (EE) has a predictive validity in an 8 year follow-up study and if this is dependent on the residential form, especially on patients and relatives living together. Eight years after a baseline examination (Camberwell Family Interviews [CFI], global assessment scale [GAS], symptom score) 69 of 99 patients were reexamined. The number and duration of rehospitalizations as well as the symptom and GAS scores were recorded. These was no difference between outcome of high and low EE patients with a duration of illness of less than 4.5 years and for those living with partners. Patients from high EE parents with a longer duration of illness (> 4.5 years) at the outset of the study were significantly more often and longer in hospital. They had significantly higher symptom and GAS scores at the outset of the study and after 8 years. The EE effect was equal in the first and second 4 years of the follow-up and was independent from patients and parents living together. The results emphasize the significance of the EE index as a long-term predictor for the course of schizophrenic illness. The independence of the prediction from living together is an argument against a simple causal interpretation of the connection between EE and the course of schizophrenia.
Methodological issues raised by clinical trials on dysthymia: assessment instruments and response criteria
Authors: Guelfi J.D. , Corruble E 
Published: July 2002

SummaryDysthymia clinical trials raise several methodological issues. The validity of the concept remains a matter of concern, as does the need for specific instruments, the difficulties in assessment of change and long-term assessments. Diagnostic criteria for inclusion should be used in a polydiagnostic approach. This paper summarises the main assessment tools and diagnostic criteria used in clinical trials on dysthymia. Severity criterion for inclusion could be a Hamilton Depression Rating Scale score (HAMD-17) between 13 and 17. The main response criteria should be a decrease of at least 50% of the total score on this scale and a final score under a predetermined limit. However, other response criteria may be useful: depression self-ratings, global assessments, general psychopathology assessments, personality and defense mechanisms, quality of life, psychosocial and functional impairment, diagnostic criteria (presence or absence) and side-effect assessment.
Psychotic disorders among inpatients with abuse of cannabis, amphetamine and opiates. Do dopaminergic stimulants facilitate psychiatric illness?
Authors: Dalmau A. , Bergman B. , Brismar B. 
Published: July 2002

SummaryWe have studied the occurrence of dual diagnoses (psychoses as well as abuse of either amphetamine, cannabis or opiates) during a 15-year period, among patients treated at Huddinge Hospital, Stockholm, Sweden. The purpose of the study is to evaluate if the different drugs were coupled to different rates of psychiatric co-morbidity. During the period in question, 461, 425 and 371 different patients respectively had been admitted at least once due to dependency on amphetamine, cannabis and opiates. Approximately 30% of the patients with a pure abuse of amphetamine or cannabis and less than 6% of the opiate abusers had been diagnosed at least once with any of the psychoses studied. Comparing the frequency of psychoses among mixed and pure abusers of illegal drugs, with and without a concomitant abuse of alcohol, we found that the co-morbidity rate for mixed opiate abusers increased significantly from 7.2 to 20.2% when alcohol abuse was also present. For abusers of amphetamine and cannabis (both pure and mixed), no differences in co-morbidity rates were seen when an abuse of alcohol was added to that of the drugs. It is difficult to find an explanation for the significant difference between the co-morbidity of pure abuse of amphetamine or cannabis on the one hand and opiates on the other. In conclusion, our findings show that the distribution of psychotic illness is high among abusers of amphetamine and cannabis, in contrast to the generally lower co-morbidity among abusers of opiates. Although these findings are consistent with earlier studies that have shown a propensity for developing psychoses among abusers of amphetamine and cannabis, one should bear in mind that this study is based on inpatients, and is not necessarily representative for all abusers of the drugs in question.

Published: July 2002

AbstractBackground:Despite a growing body of data demonstrating the benefits of multidisciplinary care in heart failure, persistently high rates of readmission, especially within the first month of discharge, continue to be documented.Aims:As part of an ongoing randomized study on the value of multidisciplinary care in a high risk (NYHA Class IV), elderly (mean age 69 years) heart failure population, we examined the effects of this intervention on previously high (20%) 1‐month readmission rates.Methods:Unlike previous studies of this approach, both multidisciplinary (MC) and routine care (RC) populations were cared for by the cardiology service, complied with adherence to clinical stability criteria prior to discharge (100% of patients) and received at least target dose angiotensin‐converting enzyme (ACE) inhibition with perindopril prior to discharge (94% of indicated patients). We analysed death and unplanned readmission for heart failure at 1 month.Results:This early report from the first 70 patients (67% male, 71% systolic dysfunction with a mean ejection fraction of 31.0 ± 6.7%) enrolled in this study demonstrates elimination of 1‐month hospital readmission in both RC and MC groups. This unexpected result represents a dramatic improvement both for this patient cohort (20% 30‐day readmission rate prior to enrolment reduced to 0% following the index admission in both care groups) and in comparison with available data.Conclusions:Critical contributors to this improvement appear to be specialist cardiology care, adherence to clinical stability criteria prior to discharge and routine use of target or high‐dose ACE inhibitor therapy prior to discharge. Widespread application of this approach may have a dramatic improvement in morbidity of CHF while limiting the escalating costs of this condition.
