Abstract
BACKGROUND Stretching has garnered significant attention in sports sciences, resulting in numerous studies. However, there is no comprehensive overview on investigation of stretching in healthy athletes. OBJECTIVES To perform a systematic scoping review with an evidence gap map of stretching studies in healthy athletes, identify current gaps in the literature, and provide stakeholders with priorities for future research. METHODS Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 and PRISMA-ScR guidelines were followed. We included studies comprising healthy athletes exposed to acute and/or chronic stretching interventions. Six databases were searched (CINAHL, EMBASE, PubMed, Scopus, SPORTDiscus, and Web of Science) until 1 January 2023. The relevant data were narratively synthesized; quantitative data summaries were provided for key data items. An evidence gap map was developed to offer an overview of the existing research and relevant gaps. RESULTS Of ~ 220,000 screened records, we included 300 trials involving 7080 athletes [mostly males (~ 65% versus ~ 20% female, and ~ 15% unreported) under 36 years of age; tiers 2 and 3 of the Participant Classification Framework] across 43 sports. Sports requiring extreme range of motion (e.g., gymnastics) were underrepresented. Most trials assessed the acute effects of stretching, with chronic effects being scrutinized in less than 20% of trials. Chronic interventions averaged 7.4 ± 5.1 weeks and never exceeded 6 months. Most trials (~ 85%) implemented stretching within the warm-up, with other application timings (e.g., post-exercise) being under-researched. Most trials examined static active stretching (62.3%), followed by dynamic stretching (38.3%) and proprioceptive neuromuscular facilitation (PNF) stretching (12.0%), with scarce research on alternative methods (e.g., ballistic stretching). Comparators were mostly limited to passive controls, with ~ 25% of trials including active controls (e.g., strength training). The lower limbs were primarily targeted by interventions (~ 75%). Reporting of dose was heterogeneous in style (e.g., 10 repetitions versus 10 s for dynamic stretching) and completeness of information (i.e., with disparities in the comprehensiveness of the provided information). Most trials (~ 90%) reported performance-related outcomes (mainly strength/power and range of motion); sport-specific outcomes were collected in less than 15% of trials. Biomechanical, physiological, and neural/psychological outcomes were assessed sparsely and heterogeneously; only five trials investigated injury-related outcomes. CONCLUSIONS There is room for improvement, with many areas of research on stretching being underexplored and others currently too heterogeneous for reliable comparisons between studies. There is limited representation of elite-level athletes (~ 5% tier 4 and no tier 5) and underpowered sample sizes (≤ 20 participants). Research was biased toward adult male athletes of sports not requiring extreme ranges of motion, and mostly assessed the acute effects of static active stretching and dynamic stretching during the warm-up. Dose-response relationships remain largely underexplored. Outcomes were mostly limited to general performance testing. Injury prevention and other effects of stretching remain poorly investigated. These relevant research gaps should be prioritized by funding policies. REGISTRATION OSF project ( https://osf.io/6auyj/ ) and registration ( https://osf.io/gu8ya ).

Abstract
Background The purpose of this study is to update results of Portuguese's Report Card on Physical activity (PA) for Children and Adolescents. Methods The grades were assigned by results derived from the PA and Fitness in Portugal 2021 Portuguese Report Card and corresponds to the third report for the Portuguese children and adolescents. It includes indicators of PA and sedentary behavior (SB) that are common to the GLOBAL matrix 4.0: Overall Physical Activity, Organized Sport and Physical Activity, Active Play, Active Transportation, Sedentary Behaviors, Family and Peers, School, Community and the Environment, Government and Physical Fitness. The search focused on published national evidence/data sources (academia, NGO, governmental) from end 2018 onwards excluding data obtained during the covid-19 pandemic. Results The grades were assigned as follows: Overall PA (D-), Organized Sport Participation (C-), Active Play (D+), Active Transportation (D-), Sedentary behaviors (C+), Physical Fitness (C), Family and Peers (B), School (A), Community and Environment (B), and Government (B). Conclusion In line with previous Portuguese Report Cards, a large proportion of Portuguese children and adolescents are not sufficiently active nor fit enough setting urgency for effective strategies. Particular attention should be given to Active play, Active transport and Organized Sports Participation has their grades have decreased. Some actions in selected indicators as Governmental and policy seems promising however results weren't seen yet. Despite the strong support of schools with mandatory curricula in PE no correspondent change is observed in fitness or PA, so more research is needed to find why.

Abstract
Data concerning the combined effect of diet and exercise interventions on overall health in the elderly are scarce. The MED-E project's primary aim is to assess the effect of the different 3-month sustainable healthy diet (SHD) and multicomponent training (MT) interventions on several health outcomes in the elderly. A quasi-experimental study assigned older adults into four groups: (1) SHD, (2) MT, (3) SHD + MT, or (4) control group (CG). The SHD intervention included a weekly offer of a mixed food supply and individual and group nutritional sessions on the principles of an SHD. The MT groups were submitted to 50-min exercise sessions three times a week. The primary outcomes were blood biomarkers and metabolic profile alterations that were assessed pre- and post-intervention. Additionally, data on dietary intake and nutritional adequacy, physical fitness, body composition and anthropometry, cognitive function, quality of life, and geographical data were assessed at the same time points. The MED-E project's study protocol and future results will add to knowledge about the importance and beneficial contribution of combined SHD and MT interventions on healthy ageing policies.

Abstract
Introducción En el hospital de La Princesa comienza el “Código Sepsis” (CSP) en el año 2015, como un grupo multidisciplinar que dota al personal sanitario de herramientas clínicas, analíticas y organizativas, con el objetivo de la detección y el tratamiento precoz del paciente con sepsis. El objetivo de este estudio es evaluar el impacto de la implantación de CSP en la mortalidad y determinar las variables asociadas con un aumento de la misma. Material y métodos Se realizó un estudio analítico retrospectivo de los pacientes con activación de la alerta CSP de 2015 a 2018. Se recogieron variables clínico-epidemiológicas, parámetros analíticos y factores de gravedad como el ingreso en Unidades de Cuidados Críticos (UCC) y la necesidad de aminas. La significación estadística se estableció en una p < 0,05. Resultados Se incluyeron 1.121 pacientes. La estancia media fue de 16 días y un 32% requirieron ingreso en UCC. La mortalidad mostró una tendencia lineal descendente estadísticamente significativa del 24% en 2015 hasta el 15% en 2018. Las variables predictivas de mortalidad con asociación estadísticamente significativa fueron el lactato > 2 mmol/L, la creatinina > 1,6 mg/dL y la necesidad de aminas. Conclusiones La implementación de Código Sepsis disminuye la mortalidad de los pacientes con sepsis y shock séptico. La presencia de una cifra de lactato > 2 mmol/L, los niveles de creatinina > 1,6 mg/dL y/o la necesidad de administrar aminas en las primeras 24 horas, se asocian con un aumento de la mortalidad en el paciente con sepsis.

Abstract
Environmental factors play an important role in obesity-related behaviors. Evidence indicates significant associations between weight and urban green spaces in adults, but it is not clear whether this relationship applies to adolescents. Therefore, our aim was to determine the associations between urban green spaces, greenness exposure and species richness in residential environments with physical activity and body mass index. Sixty-two adolescents between 12 and 18 years of age answered a self-administered questionnaire, providing information on height, weight, age, sex and home address. Data on socioeconomic deprivation were obtained from the European Index of Deprivation for Small Portuguese Areas. Physical activity levels were assessed using accelerometers. Urban green space counts and the normalized difference vegetation index values were measured using buffers along the roads with distances of 300, 500, 1000 and 1500 m from each participant's residence. To quantify the species richness, the species richness index was used. Linear regression models were fitted to analyze whether urban green spaces, exposure to green spaces and species richness counts for each distance were associated with physical activity and self-reported body mass index. We did not find significant associations between the independent variables and the probability of overweight or obesity. The relationship between environmental variables, adolescents' physical activity and body weight seems to be complex and further studies may contribute to better understanding of the topic.

Abstract
Pines are the dominant conifers in Mediterranean forests. As long-lived sessile organisms that seasonally have to cope with drought periods, they have developed a variety of adaptive responses. However, during last decades, highly intense and long-lasting drought events could have contributed to decay and mortality of the most susceptible trees. Among conifer species, Pinus pinaster Ait. shows remarkable ability to adapt to different environments. Previous molecular analysis of a full-sib family designed to study drought response led us to find active transcriptional activity of stress-responding genes even without water deprivation in tolerant genotypes. To improve our knowledge about communication between above- and below-ground organs of maritime pine, we have analyzed four graft-type constructions using two siblings as rootstocks and their progenitors, Gal 1056 and Oria 6, as scions. Transcriptomic profiles of needles from both scions were modified by the rootstock they were grafted on. However, the most significant differential gene expression was observed in drought-sensitive Gal 1056, while in drought-tolerant Oria 6, differential gene expression was very much lower. Furthermore, both scions grafted onto drought-tolerant rootstocks showed activation of genes involved in tolerance to abiotic stress, and is most remarkable in Oria 6 grafts where higher accumulation of transcripts involved in phytohormone action, transcriptional regulation, photosynthesis and signaling has been found. Additionally, processes, such as those related to secondary metabolism, were mainly associated with the scion genotype. This study provides pioneering information about rootstock effects on scion gene expression in conifers.

Abstract
BACKGROUND Dementia is a leading cause of death and disability that was declared as one of the greatest health and social care challenges of the twenty-first century. Regular physical activity and exercise have been proposed as a non-pharmacological strategy in disease prevention and management. Multicomponent Training (MT) combines aerobic, strength, balance and postural exercises and might be an effective training to improve both functional capacity and cognitive function in individuals with dementia (IwD). Nevertheless, data on the effects of MT in IwD are still limited and the extent to which IwD can retain improvements after an exercise intervention still needs to be elucidated. The aim of "Body & Brain" study is to investigate the effects of a 6-month MT intervention and 3-month detraining on the physical and cognitive function of IwD. Additionally, we aim to explore the impact of this intervention on psychosocial factors and physiologic markers related to dementia. METHODS This study is a quasi-experimental controlled trial using a parallel-group design. The study sample consists of community-dwelling individuals aged ≥60 years who are clinically diagnosed with dementia or major neurocognitive disorder. Participants will be either allocated into the intervention group or the control group. The intervention group will participate in MT biweekly exercise sessions, whereas the control group will receive monthly sessions regarding physical activity and health-related topics for 6 months. The main outcomes will be physical function as measured by the Short Physical Performance Battery (SPPB) and cognitive function evaluated using the Alzheimer Disease Assessment Scale - Cognitive (ADAS-Cog) at baseline, after 6-months and 3-months after the end of intervention. Secondary outcomes will be body composition, physical fitness, daily functionality, quality of life, neuropsychiatric symptoms and caregiver's burden. Cardiovascular, inflammatory and neurotrophic blood-based biomarkers, and arterial stiffness will also be evaluated in subsamples. DISCUSSION If our hypothesis is correct, this project will provide evidence regarding the efficacy of MT training in improving physical and cognitive function and give insights about its impact on novel molecular biomarkers related to dementia. This project may also contribute to provide guidelines on exercise prescription for IwD. TRIAL REGISTRATION ClinicalTrials.gov - identifier number NCT04095962 ; retrospectively registered on 19 September 2019.

Abstract
Advances in flow monitoring are crucial to increase our knowledge on basin hydrology and to understand the interactions between flow dynamics and infrastructures. In this context, image processing offers great potential for hydraulic monitoring, allowing acquisition of a wide range of measurements with high spatial resolution at relatively low costs. In particular, the particle tracking velocimetry (PTV) algorithm can be used to describe the dynamics of surface flow velocity in both space and time using fixed cameras or unmanned aerial systems (UASs). In this study, analyses allowed exploration of the optimal particle seeding density and frame rate in different configurations. Numerical results provided useful indications for two field experiments that have been carried out with a low-cost quadrocopter equipped with an optical camera to record RGB videos of floating tracers manually distributed over the water surface. Field measurements have been carried out using different natural tracers under diverse hydraulic and morphological conditions; PTV's processed velocities have been subsequently benchmarked with current meter measurements. The numerical results allowed rapid identification of the experimental configuration (e.g., required particle seeding density, image resolution, particle size, and frame frequency) producing flow velocity fields with high resolution in time and space with good agreement with the benchmark velocity values measured with conventional instruments.

Abstract
BACKGROUND The effect of a pre-exercise meal as countermeasure to exercise induced immunodepression is poorly known. Also, sedentary behavior is associated with increased cardiometabolic risk but studies on immune changes are lacking. Therefore, we aimed to assess: 1) the impact of a pre-exercise Mediterranean meal (MdM) compared with a fast-food type meal (FFM) on exercise-induced immunological changes and 2) the impact of an induced acute period of sedentary behavior on neuro-immune-endocrine status. METHODS /Design: This is a two steps clinical trial including: (a) randomized crossover clinical trial, comparing the effect a high-fat/low-nutrient dense meal, FFM, with an isoenergetic similar high-nutrient dense meal, MdM, in the immune response to an exercise challenge (EC) and (b) a pilot trial assessing the neuro-immune-endocrine change induced by acute decreasing by half the usual physical activity level. RESULTS A total of 46 participants (26 females), median aged 25 years were included. Of those 39-completed protocol, including overweight, physical active and inactive and participants with asthma. There were no differences in the EC between interventions. Dietary factors and physical activity were closely monitored during interventions and kept similar. During physical inactivity induction, 31% reached the target of 50% reduction in mean step number and 77% reached a 30% reduction. CONCLUSION The use of a pre-exercise meal to modulate immune response and the understanding of the immunological impact of physical inactivity might help to establish future recommendations on how to practice exercise in a safer way and to recognize the potential impact of inactivity.

Abstract
BACKGROUND Inverted follicular keratosis (IFK) is an uncommon benign tumour of the follicular infundibulum, which is often misdiagnosed clinically as other keratinizing tumours, and commonly diagnosed correctly by histopathology. There are few reports about the dermoscopic findings of this lesion. AIM To evaluate the dermoscopic features of IFK. METHODS The dermoscopic structures and patterns in digital dermoscopic images of 12 histopathologically confirmed cases of IFK collected from 5 hospitals in Spain were evaluated. RESULTS A keratoacanthoma (KA)-like pattern composed of central keratin surrounded by hairpin vessels in a radial arrangement was the most common pattern in IFK (58.3%). The second most common pattern was composed of a yellowish-white amorphous central area surrounded by vascular structures in a radial arrangement (33.3%). The remaining case showed a pattern composed of a yellowish-white amorphous central area with milky red globules. Vascular structures were present in all cases, with a monomorphic pattern in seven cases and a polymorphic pattern in five, mainly with radial arrangement. Arborizing vessels, linear irregular vessels, corkscrew vessels and milky red globules were present in some cases. CONCLUSIONS We describe the two main patterns of IFK. Lesions with a KA-like pattern are clinically and dermoscopically undistinguishable from KA and squamous cell carcinoma. Cases with a polymorphic vascular pattern could be confused with malignant tumours, including basal cell carcinoma and amelanotic melanoma.

Abstract
The immunohistochemical expression of E-cadherin (E-CD) was correlated to differentiation grade, tumor size, axillary lymph node metastasis, hormone receptor status and disease outcome in 230 infiltrating ductal breast carcinomas. E-CD expression was reduced in 116 tumors (50.4%). Reduced E-CD expression was more frequently found in high histological grade and progesterone receptor negative tumors. In contrast, preserved E-CD expression was more frequently observed in tumors with axillary lymph node metastasis, particularly in the group of patients with 1 to 3 positive lymph nodes. A weak association between reduced E-CD expression and shortened overall survival was found in univariate survival analysis, that was lost when the patients were adjusted for other pathological factors in multivariate analysis. These data indicate that E-CD may be considered a differentiation marker in ductal carcinomas of non special type. However, the relationship between E-CD expression and lymph node metastasis and disease outcome remains to be established.

Abstract
BACKGROUND Glutathione S-transferases (GSTs) GSTM1, GSTT1 and GSTP1 are multifunctional enzymes involved in the detoxification of a wide range of reactive oxygen species produced during melanin synthesis and oxidative stress processes. OBJECTIVES Single nucleotide polymorphisms (SNPs) in GSTP1 and copy number variants in GSTM1 and GSTT1 may be candidate low-penetrance variants with a role in susceptibility to malignant melanoma (MM). METHODS In this case-control study, 562 Spanish patients with sporadic MM and 338 cancer-free control subjects were included, and the role of polymorphisms in these GST genes was investigated. Genotypes were established by quantitative real-time polymerase chain reaction for GSTM1 and GSTT1 while TaqMan probes were used to genotype GSTP1 SNPs. RESULTS The GSTP1 polymorphism rs1695, which encodes the amino acid change p.Ile105Val, was individually associated with MM [odds ratio (OR): 1·32, 95% confidence interval (CI): 1·06-1·63]. Furthermore, individuals carrying one or two MC1R nonsynonymous changes and GSTP1 rs1695 rare allele had an increased risk of developing MM (OR: 3·34, 95% CI: 1·42-8·09 and OR: 20·42, 95% CI: 2·80-417·42, respectively). CONCLUSIONS This is the first time that the GSTP1 rs1695 polymorphism is reported to be associated with MM. In addition, this study is one of the largest GST polymorphism studies undertaken in the Spanish population and the first time that copy number variants have been scrutinized in relation to MM.

Abstract
Congenital malignant melanoma within a pre-existing large congenital melanocytic naevus (CMN) is exceedingly rare. Its incidence is difficult to determine due to the small number of reported cases and because of problems associated with diagnosis. Some benign nodular proliferations (called proliferative nodules) arising in CMN, while rare, are significantly more common and can mimic malignant melanoma clinically or histologically. There are no reported cases of congenital melanoma or benign proliferative nodules in CMN in patients who also had eruptive disseminated Spitz naevi. We describe a girl who was noted to have a dark-brown plaque with several large erythematous nodules affecting the scalp at delivery, in addition to multiple erythematous dome-shaped papules that developed in a disseminated manner over several months, beginning at 10 days of age. It was difficult, not only clinically but also histologically, to determine the benign or malignant nature of all of these lesions. As primary cutaneous melanoma, atypical proliferative nodules in CMN, bland CMN or CMN with foci of increased cellularity and Spitz naevi show clear differences in the genetic aberration patterns, comparative genomic hybridization (CGH) could be a diagnostic help in ambiguous cases such as this. CGH performed on this patient showed multiple DNA copy number changes in the most atypical nodule, but such alterations could not be found in the remainder of the lesions. CGH showed differences between the nodular lesions that occurred in the CMN and helped us in supporting the diagnosis of this unique case of benign proliferative nodules and a possible congenital melanoma arising in a large CMN, associated with multiple widespread eruptive Spitz naevi.

Abstract
BACKGROUND The incidence of malignant melanoma has increased over recent decades. Early diagnosis continues to be essential for effective treatment. Our objective was to analyze cutaneous malignant melanomas diagnosed over a 15-year period in a tertiary hospital for trends towards earlier diagnosis and to identify subgroups with poorer prognosis. MATERIAL AND METHODS Retrospective analysis of primary cutaneous melanomas analyzed in the pathology department of Hospital La Paz, Madrid, Spain, between 1990 and 2004. RESULTS In total, 526 melanomas were diagnosed. The mean (SD) Breslow thickness was 2.63 (4.84) mm and the median thickness was 0.98 mm (range, 0-65 mm). The mean size (widest point) was 16.59 (12.11) mm. The most common histological type was surface-spreading melanoma and the most common site was the trunk. Melanomas detected in men were generally larger and thicker than in women (P=0.05). Individuals aged over 60 years consulted for significantly thicker and larger tumors than younger individuals. The incidence of malignant melanomas has increased steadily over the years whereas the mean Breslow thickness and size have decreased. CONCLUSIONS Diagnosis of melanoma in Spain is made increasingly earlier, although locally advanced tumors are still sometimes seen in men and in individuals aged over 60 years.

Abstract
The association of specific genetic disturbances with the development of hereditary cancer helps us to understand the risk of suffering from it, the possibility of an earlier diagnosis, and the treatment and prevention of this disease. Familial adenomatous polyposis (FAP) is a pre-neoplastic syndrome characterized by the presence of hundreds of adenomatous polyps in the colon, which develop into a carcinoma. FAP can be diagnosed using sequencing techniques to detect mutations in the germinal line of the APC (adenomatous polyposis coli) gene. The genetic diagnostic approach in families with FAP, previously followed up in the Gastrointestinal Clinic, has both advantages and disadvantages, and places us nearer the disease and patient. Disclosing the results of this genetic test entails relevant problems in clinical practice, which affect the health field and raise legal and ethical issues, along with the familial, occupational, and social implications that knowing the genetic status can have on the patient. Genetic analysis is rare in normal clinical practice, which involves errors in the interpretation of the results obtained, and during the process of genetic counselling. Specialized multidisciplinary units are necessary for the management of patients with FAP undergoing analysis and appropriate genetic counselling, thus providing an individualized service. The creation of FAP registers and protocols for this healthcare process should optimize the management of these patients and their families.

Abstract
Gene expression microarrays are a relatively new technology, dating back just a few years, yet they have already become a very widely used tool in biology, and have evolved to a wide range of applications well beyond their original design intent. However, while the use of microarrays has expanded, and the issues of performance optimization have been intensively studied, the fundamental issue of data integrity management has largely been ignored. Now that performance has improved so greatly, the shortcomings of data integrity control methods constitute a greater percent of the stumbling blocks for investigators. Microarray data are cumbersome, and the rule up to this point has mostly been one of hands-on transformations, leading to human errors which often have dramatic consequences. We show in this review that the time lost on such mistakes is enormous and dramatically affects results; therefore, mistakes should be mitigated in any way possible. We outline the scope of the data integrity issue, to survey some of the most common and dangerous data transformations, and their shortcomings. To illustrate, we review some case studies. We then look at the work done by the research community on this issue (which admittedly is meager up to this point). Some data integrity issues are always going to be difficult, while others will become easier-one of our goals is to expedite the use of integrity control methods. Finally, we present some preliminary guidelines and some specific approaches that we believe should be the focus of future research.

Abstract
OBJECTIVES Analysis of all cases of tetrabamate (Atrium)-induced hepatotoxicity reported in the Andalusian Registry of drug-induced liver disorders and comparison with cases reported in the literature. MATERIAL AND METHOD Information was gathered in a structured protocol. The causal role of tetrabamate was estimated in each case using the diagnostic scale of the Council for International Organizations of Medical Sciences (CIOMS). RESULTS Of 327 cases of hepatotoxicity, 7 (2%) were due to tetrabamate. The mean age was 57 years (4 men). In 57% of the cases, the presenting symptom was tremor. The latency period was between 15 and 730 days. Liver damage was mainly cytolytic without signs of hypersensitivity. In all cases outcome was favorable with complete recovery between 60 and 120 days. The CIOMS diagnostic scale rated a causal role of tetrabamate as highly probable in six cases and as probable in one. CONCLUSION Tetrabamate can induce hepatotoxicity, probably due to an idiosyncratic metabolic mechanism. Because of this finding and the existence of more appropriate therapeutic alternatives, tetrabamate should not be used in the treatment of alcohol withdrawal.

Abstract
OBJECTIVE Eighty-two episodes of polymicrobial bacteremia in two time periods, 1986-87 and 1996-97, were compared to assess differences in risk factors and outcome to mortality. METHODS A prospective, concurrent, anterograde study with univariate analysis of all episodes of polymicrobial bacteremia was performed in Hospital de la Princesa. Logistic regression analysis was applied to all significant variables (p < 0.05) in the univariate analysis in either of the two time periods. RESULTS Variables showing statistically significant differences in incidence between the two time periods included the following: hospital acquired bacteremia; previous use of antibiotics; genitourinary, respiratory and cardiovascular manipulations; septic metastases; and absence of leukocytosis. These factors were more frequently present during 1986-87 than during 1996-97. The overall RR of outcome to mortality was five-fold greater during the first period than the second: RR 5.6 (CI 1.76-17.56) p < 0.001. The clinical characteristics at the onset of bacteremia associated with mortality in the first period were: underlying disease - < RR 2.20 (CI 1.18-4.08), steroid treatment - < RR 4.24 (CI 0.68-26.59), hypotension - < RR 2.05 (CI 1.0-4.17), and disseminated intravascular coagulation - < RR 2.31 (CI 1.69-3.35). Clinical characteristics at the onset of bacteremia associated with mortality in the second period were: hypotension - < RR 1.44 (CI 1.01-2.08), underlying disease - < RR 1.16 (CI 1.02-1.34), and disseminated intravascular coagulation - < RR 6.40 (CI 1.15-35.69). The variables independently associated with mortality in polymicrobial bacteremia were: period - < RR 2.05 (CI 1.50-2.10), underlying disease - < RR 7.05 (CI 2.68-7.50), hypotension - < RR 7.06 (CI 3.80-7.29), and (probably) vascular manipulations - < RR 3.41 (CI 0.85-4.53). CONCLUSION Polymicrobial bacteremia-associated mortality was five-fold greater in 1986-87 than in 1996-97. The variables independently associated with mortality risk were underlying disease, hypotension, the period studied (which would include a number of variables not analyzed in this work) and, probably, vascular manipulations.

Abstract
Two novel sterically hindered cisplatin derivatives with the ligand L=NH(2)C(CH(2)CH(2)COOH)(3) were prepared: cis-PtCl(2)L(2) and cis-PtCl(2)L(NH(3)). The starting compound for the syntheses was NH(2)C(CH(2)CH(2)COOtBu)(3), also known as a building block for dendrimers. cis-PtCl(2)L(2) was prepared from K(2)PtCl(4) in an unusual two-phase reaction in water-chloroform, followed by deprotection of the tert-butyl protective groups with formic acid to yield a water-soluble complex. The mixed-ligand compound cis-PtCl(2)L(NH(3)) was prepared from [PPh(4)][PtCl(3)(NH(3))] in methanol, with subsequent deprotection in formic acid. DNA-binding properties of the two compounds were investigated using the model base guanosine-5'-monophosphate (5'-GMP) and pBR322 plasmid DNA. While cisplatin [cis-PtCl(2)(NH(3))(2)] induced an unwinding of 12 degrees in pBR322 plasmid DNA, cis-PtCl(2)L(NH(3)) induced only 3 degrees unwinding, which is indicative of a monofunctional binding mode. Remarkably, cis-PtCl(2)L(2) did not induce any distortion in plasmid DNA, which strongly suggests that the compound does not bind to DNA. Test reactions with 5'-GMP, monitored by 1H and 195Pt NMR, confirmed that cis-PtCl(2)L(2) is unable to bind to DNA, whereas cis-PtCl(2)L(NH(3)) binds only one nucleotide. Apparently, binding of platinum to nucleotides at the coordination site cis with respect to the ligand L is prevented by steric crowding. Thus, cis-PtCl(2)L(NH(3)) must bind DNA monofunctionally at the trans position. Besides, both compounds have a chloride replaced by one of the carboxylate arms, forming a a seven-membered chelate ring. In theory, cis-PtCl(2)L(2) could also form a second chelate ring, but this was not observed.

Abstract
MOTIVATION AND RESULTS A relational schema is described for capturing highly parallel gene expression experiments using different technologies. This schema grew out of efforts to build a database for collaborators working on different biological systems and using different types of platforms in their gene expression experiments as well as different types of image quantification software. The tables are conceptually organized into three categories of information: Platform, Experiment (which includes image scanning and quantification), and Data. The strengths of the schema are: (i) integrating information on array elements using a gene index; (ii) describing samples using ontologies; (iii) reducing an experiment to a single RNA source for precise descriptions yet not losing the relationships between experiments done at the same time or for the same project; and (iv) maintaining both raw and processed (e.g. cleansed and normalized) data and recording how the data is processed. The result is a novel schema, which can hold both array and non-array data, is extensible for detailed experimental descriptions that are precise and consistent, and allows for meaningful comparisons of genes between experiments.

Abstract
BACKGROUND There is evidence to postulate that undernotification is the reason for the great decrease in the reported incidence of hydatidosis in Chile. AIM To develop and propose a method to assess the notification of transmissible diseases, based on observed lethality and hospital discharges. MATERIAL AND METHODS Human hydatidosis in the period 1985-1994 was used as a model to develop the method. Official reports and mortality were analyzed first, determining the first lethality rate. A second lethality rate was calculated based on hospital discharges and a third, based on all Chilean surgical series published in the last two decades. Adjusting official notification of lethality to the true lethality according to surgical series, the number of unreported cases was calculated and the true incidence of hydatidosis was calculated, summing these cases to the official notification. RESULTS According to this method, the real rates of human hydatidosis in the period 1985-1994, would fluctuate between 6.5 and 11.4 per 100,000. This figure is four times higher than the official notification in the analysed period. CONCLUSIONS The correction of under notification based on hospital discharges, with or without correction for repeated hospital admissions, or real mortality of surgical series gave similar results, suggesting that both methods are correct.

Abstract
The treatment of small-cell lung carcinoma (SCLC) requires the careful combination of chemotherapy and radiation therapy. To understand the factors involved in the outcome of these patients, the authors undertook a study of patients treated for limited stage SCLC. The charts of 194 consecutive patients treated at our facilities between 1986 and 1994 were reviewed. All patients underwent thoracic radiation therapy (TRT), 50% received prophylactic cranial irradiation (PCI), and all but one received chemotherapy. The probability of survival at 5 years was 14%, and the disease-free survival (DFS) was 17%. Patients receiving a combination of platinum and etoposide (PE) and Cytoxan (Bristol-Myers, Evansville, IN, U.S.A.), Adriamycin (Adria Laboratories, Dublin, OH, U.S.A.), and Vincristine (Eli Lilly, Indianapolis, IN, U.S.A.) (CAV) experienced a DFS at 3 years of 31%, versus 14% for CAV only and 18% for PE only (p = 0.004). In a multivariate survival analysis, only PCI (p = 0.001), having received PE and CAV (p = 0.01), and response to treatment (p = 0.001) were significant. Radiation dose and field size did not influence outcome. The combination of PE and CAV chemotherapy produced the best results in our series. Unanswered questions regarding the optimal TRT dose, field size, and timing of TRT await the results of ongoing randomized trials.

Abstract
Rolipram, a phosphosdiesterase type IV-specific inhibitor, prevented p24 antigen release from anti-CD3-activated human immunodeficiency virus (HIV)-infected T cells and CD4(+)-cell depletion associated with viral replication in a dose-responsive manner but minimally inhibited T-cell proliferation. Moreover, rolipram reduced the production of tumor necrosis factor alpha (TNF-alpha) and interleukin-10 (IL-10) by HIV-infected T cells. The transcriptional ability of a luciferase reporter gene under control of the HIV long terminal repeat, induced by phorbol myristic acetate plus ionomycin or by TNF-alpha, in primary T and Jurkat cells was also inhibited by rolipram. Rolipram inhibited NF-kappaB and NFAT activation induced by T-cell activation in Jurkat and primary T cells, as measured by transient transfection of reporter genes and electrophoretic mobility shift assays. Exogenous addition of TNF-alpha in the presence of rolipram restored NF-kappaB but not NFAT activation or p24 release. Addition of dibutyryl-cyclic AMP (dBcAMP) mimicked the effects of rolipram on p24 antigen release, NF-kappaB activation, and TNF-alpha secretion, but it did not affect NFAT activation or IL-10 production. The protein kinase A inhibitor KT5720 prevented the inhibition of TNF-alpha secretion but not that of HIV type 1 (HIV-1) replication caused by rolipram. Our data indicate that blockade of phosphodiesterase type IV could be of benefit against HIV-1 disease by modulating cytokine secretion and transcriptional regulation of HIV replication, and they suggest an important role of NFAT in HIV replication in primary T cells. Some of those activities cannot be ascribed solely to its ability to increase cAMP.

Abstract
The effect of exposure to 60-Hz electromagnetic fields (EMFs) on RNA coliphage MS2 replication was studied. EMF exposure commenced when the bacterial cultures were inoculated with the phage (t = 0). In 12 experiments in which the strength of the field was 5 G, a significant delay in phage yield was found in the EMF-exposed cultures 45-65 min after inoculation, compared with control cultures. However, the EMF did not alter the final phage concentration. Experiments at 25 G (N = 5) suggested that the stronger field resulted in both impeded phage replication and increased phage yield. No differences between test groups were found in experiments involving sham-EMF exposure, thereby indicating that the results obtained with the EMFs were not due to systematic error. It appears that MS2, which codes for only four proteins, is the simplest biological system in which an EMF-induced effect has been demonstrated. The MS2 system is, therefore, conducive to follow-up studies aimed at understanding the level and nature of the underlying interaction process, and perhaps to biophysical modeling of the interaction process.

Abstract
We report an unusual case of nonscarring alopecia clinically resembling patchy alopecia areata around central solitary circumscribed neuroma. Prompt and spontaneous complete hair regrowth was observed after removal of the tumor. Further knowledge of growth factor and receptor interaction in regulating the hair follicle cycle, as well as on the production of growth factors and cytokines by tumor cells and/or cells within the tumor microenvironment may contribute to better understand the pathologic mechanisms underlying certain curious phenomena such as peritumoral nonscarring alopecia.
