RESUMO
Land-use change can alter trophic interactions with wide-ranging functional consequences, yet the consequences for aquatic food webs have been little studied. In part, this may reflect the challenges of resolving the diets of aquatic organisms using classical gut contents analysis, especially for soft-bodied prey. We used next-generation sequencing to resolve prey use in nearly 400 individuals of two predatory invertebrates (the Caddisfly, Rhyacophila dorsalis, and the Stonefly Dinocras cephalotes) in streams draining land with increasingly intensive livestock farming. Rhyacophila dorsalis occurred in all streams, whereas D. cephalotes was restricted to low intensities, allowing us to test whether: (i) apparent sensitivity to agriculture in the latter species reflects a more specialized diet and (ii) diet in R. dorsalis varied between sites with and without D. cephalotes. DNA was extracted from dissected gut contents, amplified without blocking probes and sequenced using Ion Torrent technology. Both predators were generalists, consuming 30 prey taxa with a preference for taxa that were abundant in all streams or that increased with intensification. Where both predators were present, their diets were nearly identical, and R. dorsalis's diet was virtually unchanged in the absence of D. cephalotes. The loss of D. cephalotes from more intensive sites was probably due to physicochemical stressors, such as sedimentation, rather than to dietary specialization, although wider biotic factors (e.g., competition with other predatory taxa) could not be excluded. This study provides a uniquely detailed description of predator diets along a land-use intensity gradient, offering new insights into how anthropogenic stressors affect stream communities.

Transforming growth factor ß-1, encoded by the TGFB1 gene, is a cytokine that plays a central role in many physiologic and pathogenic processes with pleiotropic effects. Regulatory activity for this gene has been shown for 3.0 kb between positions -2665 and +423 from its translational start site. At least 17 TGFB1 regulatory region and exon 1 alleles have been defined on the basis of 18 polymorphic sites. Polymorphisms in TGFB1's regulatory region have been associated with differential levels of expression of this cytokine and to genetic risk in cancer and transplantation. In this report, we present 19 novel TGFB1 regulatory region and exon 1 alleles: p018-p036. Amplification of TGFB1's regulatory region was performed with an in-house protocol, and novel alleles were defined by either allele-specific amplification and/or molecular cloning of the amplicons, followed by sequencing in isolation. Three of these novel alleles (p018, p019, and p020) are shown to be formed by novel combinations of the aforementioned known polymorphic positions. Another 16 novel alleles are shown to carry additional known and unknown single-nucleotide polymorphisms. Polymorphism in TGFB1's regulatory region could have an impact on important processes, including embryogenesis, hematopoiesis, carcinogenesis, angiogenesis, fibrosis, immune responses, and transplantation, making its characterization necessary.

Patients diagnosed with primary brain tumors such as glioma experience psychological distress throughout the illness trajectory. Determining which patient characteristics are associated with more severe mood disturbance throughout the illness trajectory can help identify patients at risk and assist in developing targeted interventions based on these factors. Adult glioma patients were eligible for participation. Data collection tools included an investigator completed clinician assessment tool, patient completed demographic form and the Profile of mood states-short form. A multiple regression model was used to describe the relationship between the patient groups and clinical factors. The study enrolled 186 glioma patients of various tumor grades, who were categorized in three groups (newly diagnosed, on-treatment, follow-up) based on disease status at time of visit. Newly diagnosed patients experienced more total mood disturbance than all the other groups. Characteristics associated with more severe mood disturbance varied by patient group: newly diagnosed patients who were not on corticosteroids and were not married were more likely to have higher mood disturbance [R(2) = 0.27, F (2, 29) = 5.31, p < 0.02]. For those on treatment, the use of concomitant medications, having more than 1 recurrence and low income predicted higher mood disturbance [R(2) = 0.417, F (4, 67) = 11.98, p < 0.001]. For those not on active treatment, female sex, anti-depressant use and having a lower income was associated with higher mood disturbance [R(2) = 0.183, F (3, 55) = 4.11, p < 0.02]. Additionally, when compared to other cancer groups, glioma patients reported similar mood disturbance to those with breast cancer. Factors other than disease characteristics are associated with higher mood disturbance and vary according to current disease status. The use of concomitant medications, demographic factors, recurrence and income are associated with mood disturbance and interventions may need to be tailored to these underlying factors.

Hematopoietic stem cell transplantation (HSCT) is a medical procedure used to treat malignant and nonmalignant haematological diseases, congenital immunodeficiency syndromes, solid tumours and metabolic diseases. Despite its usefulness, several major complications, such as graft-versus-host disease, can negatively affect patients treated with HSCT. Apart from clinical factors well known to affect the outcome of HSCT, patient and donor genetics have been shown to play an important role in the susceptibility to post-transplant complications. Histocompatibility as determined by the human leucocyte antigen (HLA) system has been a major genetic determinant of the success of HSCT. Non-HLA immunogenetics are increasingly recognized to play a part in the events related to transplantation. Cytokine genes, and their receptors, bear a considerable amount of polymorphism. One of the genes that may play an important role on the outcome of allogeneic HSCT is TGFB1, which encodes transforming growth factor, ßeta 1 (TGF-ß1). TGF-ß1 is a pleiotropic cytokine, which plays a central role in the development, homeostasis and responses of the immune system. Several functional polymorphisms in TGFB1 have been identified, and these are known to cause alterations in cytokine secretion in several settings. The present review will focus on the current knowledge surrounding the effect of polymorphisms within TGFB1 on the outcome of HSCT.

The fruits and seeds of Cucurbita ficifolia Bouché are sources of minerals, vitamins, and functional compounds with nutraceutical and preventive potential against cardiovascular diseases and diseases derived from eating disorders. C. ficifolia is native from Mesoamerica and is currently cultivated in temperate zones from Mexico to South America and Asia. This study evaluated the fruit mesocarps of C. ficifolia for physicochemical parameters, antioxidant activity, and phenolic compound contents in a collection of farmers' landraces. Germplasm is cultivated by traditional farmers in the temperate zones of two municipalities from Oaxaca, Mexico. The results show that the content of soluble solid contents (SSC), pH, total sugars (TS), and flavonoids are influenced by the fruit geographical origin (municipalities) and implicitly by their agroecological cultivation conditions (Huamelúlpam: SSC = 6.22 °Brix, pH = 5.44, TS = 0.52 mg G g-1, flavonoids = 1.24 mg CE g-1; Yanhuitlán: SSC = 6.69, pH = 5.33, TS = 0.55, flavonoids = 1.30). Among populations preserved by traditional farmers, significant differences, and wide variability were found for all parameters evaluated (Huamelúlpam: SSC = 4.9-7.3, pH = 5.5-5.8, TS = 0.4-0.7, protein = 5.8-11.4, polyphenols = 1.9-4.8, flavonoids = 1.0-1.5, DPPH = 4.3-10.6, and FRAP = 4.8-11.8; Yanhuitlán: SSC = 4.3-8.9, pH = 4.8-5.6, TS = 0.4-0.7, protein = 5.0-15.3, polyphenols = 1.9-4.9, flavonoids = 0.8-1.9, DPPH = 5.3-10.5, and FRAP = 4.5-12.6). Eight compounds were identified by UPLC-MS: L-phenylalanine, an amino acid that is regularly associated with proteins; vanillin, a phenolic aldehyde with its functional groups including aldehyde, hydroxyl, and ether; and six phenolic acids: 4-hydroxybenzoic acid, 4-hydroxyphenylacetic acid, vanillic acid, 4-coumaric acid, ferulic acid, and salicylic acid, all with potential health effects. The C. ficifolia fruit mesocarp has bioactive compounds with high antioxidant activity with the potential to both improve diet and to obtain other benefits against nontransmissible diseases derived from food and its associated risk factors.
RESUMO
Haemophilia is the most frequent hereditary haemorrhagic illness and it is due to the deficiency of coagulation factors VIII (haemophilia A, HA) or IX (haemophilia B, HB). The prevalence of this disease varies according to the country, those having better survival rates having also higher prevalences. Specifically in Costa Rica, there are around 130 HA and 30 HB families. This study reports the prevalence and a spatial distribution analysis of both types of the disease in this country. The prevalence of haemophilia in this country is 7 cases per 100000 men, for HA it is 6 cases per 100000 and for HB it is 1 case per 100000 male inhabitants. The prevalence of this disease is low when compared with other populations. This low prevalence could be due to the many patients that have died because of infection with human immunodeficiency virus during the 1980s. The prevalence of haemophilia in Costa Rica is almost one half of that present in developed countries. Nevertheless, the ratio between HA and HB follows world tendency: 5:1. In this study, nationwide geographical distribution maps were drawn in order to visualize the origin of severe cases and how this influences the pattern of distribution for both types of haemophilia. By means of these maps, it was possible to state that there is no association between the sites of maximum prevalence of mutated alleles and ethnicity. With this study, haemophilia prevalence distribution maps can be used to improve efforts for the establishment of hemophilia clinics or specialized health centers in those areas which hold the highest prevalences in this country. Also, this knowledge can be applied to improve treatment skills and offer the possibility of developing focused genetic counseling for these populations.

The HLA system shows the most extensive polymorphism in the human genome. Allelic and haplotypic frequencies of HLA genes vary dramatically across human populations. Due to a complex history of migration, populations in Latin America show a broad variety of admixture proportions, usually varying not only between countries, but also within countries. Knowledge of HLA allele and haplotype frequencies is essential for medical fields such as transplantation, but also serves as a means to assess genetic diversity and ancestry in human populations. Here, we have determined high-resolution HLA-A, -B, -C, and -DRB1 allele and haplotype frequencies in a sample of 713 healthy subjects from three Mestizo populations, one population of African descent, and Amerindians of five different groups from Costa Rica and Nicaragua and compared their profiles to a large set of indigenous populations from Iberia, Sub-Saharan Africa, and the Americas. Our results show a great degree of allelic and haplotypic diversity within and across these populations, with most extended haplotypes being private. Mestizo populations show alleles and haplotypes of putative European, Amerindian, and Sub-Saharan African origin, albeit with differential proportions. Despite some degree of gene flow, Amerindians and Afro-descendants show great similarity to other Amerindian and West African populations, respectively. This is the first comprehensive study reporting high-resolution HLA diversity in Central America, and its results will shed light into the genetic history of this region while also supporting the development of medical programs for organ and stem cell transplantation.

INTRODUCTION: lack of evidence in most clinical situations regarding irritable bowel syndrome (IBS) enhances the importance of an expert s opinion, which will guide management and even the concept underlying the disease. OBJECTIVE: to delve into the knowledge and degree of agreement on main clinical skills for this syndrome among physicians involved in its management. MATERIAL AND METHOD: two rounds of a Delphi survey were conducted on 100 physicians: general practitioners (GPs) and gastroenterologists. The questionnaire evaluated agreement among participants in some aspects regarding the definition, diagnosis, and treatment of IBS. RESULTS: fifty-five percent of participants completed the two-round survey. Agreement was achieved regarding the definition of typical symptoms and red flags characterizing IBS. Although there was no consensus regarding the appropriate management of patients without alarm symptoms, the performance of a colonoscopy on any patient presenting red flags was suggested. Patients were thought to require a wider examination when older than 40. A well defined line of IBS treatment was not found, albeit most physicians tended to choose it depending on the main complaint. CONCLUSION: interviewed physicians showed adequate theoretical knowledge of IBS, but lack of uniformity on diagnosis and treatment approach reflects the controversial day-by-day management of this syndrome.

INTRODUCTION: Up to 5% of the population suffers from neuropathic pain (NP). A bibliographical search in several databases revealed that, to date, there are no protocols to guide physicians who are not specialists in pain that enable them to treat NP and thus improve patients' quality of life. AIMS: The aim of this study is to provide Spanish-speaking physicians who are not specialists in pain with a set of guidelines for the treatment of NP. A bibliographical search was performed in order to base the results and conclusions on the evidence-based medicine methodology. DEVELOPMENT: First, we review the most effective clinical and paraclinical methods for diagnosing NP, and the LANSS pain scale is reported as the most appropriate method of clinically evaluating NP. The anatomical paths and the physiology of pain are then described and we review the molecular variables involved. Finally, we point out the current therapeutic options and propose an algorithm for the treatment of NP. CONCLUSIONS: There is no specific set of guidelines for the treatment of NP. At the present time, the keystone of NP treatment consists in the use of antidepressant and anticonvulsive drugs. There is a need for further clinical trials to prove the effectiveness of using combined medication.

AIM: The objective of this study is to investigate the perception that people with type 2 diabetes have about the disease and about their relationship with the primary healthcare professionals. DESIGN: Qualitative research, carried out between September-November 2000. SETTING: Primary healthcare center Barrio del Pilar from Madrid. PARTICIPANTS: 15 persons with type 2 diabetes. Variables considered to design the profiles of the interviewed were: age, gender, educational level, and time since diagnosis. METHOD: Structural sampling and open interviews. RESULTS: Patients express having scarce information regarding the consequences of diabetes. As diabetes is symptom free represents a difficulty for being perceived as a severe disease. The most valued aspects of the relationship with health professionals are that they provide with clear and tailored information, build a trust context, support changes and take account their perspectives and living circumstances. CONCLUSIONS: It is essential to recognize how patients understand and shape the disease. Information provided by professionals have to be tailored to patients necessities, and take place in a trusting environment. Decisions related with diabetes management have to be aligned with patients perspectives. Effective communication could be considered as a useful tool to encourage adherence and improve healthcare quality.

RESUMO
Thirty children with lead intoxication were studied at the Hospital de Ninos Benjamin Bloom of San Salvador, during a period of eight years. Six cases were diagnosed retrospectively, whereas twenty-four were prospectively observed. Most of tham were between one to five years of age. The most common initial signs were related to the central nervous system and gastrointestinal tract. Mild and severe cases were treated with edathamil calcium disodium (Versanate), presenting successful outcome. A high incidence of muscular, neurological, bone and psychological sequels was observed. Preventive procedures and general management are emphasized.

Antisera to human oral epithelial cells were produced in rabbits and found to be specific for epithelial type cells of man, guinea-pig and rabbit. Binding of the antisera to human oral epithelial cells was not affected by pre-incubation in concanavalin A, trypsin or neuraminidase, nor by pre-incubation of the antisera with fetuin. The antisera would appear to differ from pemphigus antiserum.

Interstitial nephritis secondary to analgesic ingestion is apparently an uncommon subject in pediatric literature. Two cases are reported in this article: case 1 is a girl followed for the last fifteen years when she had lipoid nephrosis which was treated initially with corticosteroids; she responded satisfactorily, but presented frequent relapses. After 8 years, she was given cyclophosphamide plus prednisone and lately, she responded and has remained well. Further on, her urinalysis showed specific gravity of 1,033 and no proteinuria. Five years ago, because of protracted headache due to psychological disturbance, she started to ingest a variety of analgesics in progressively increasing doses. For the last 2 years, abdominal pains, paleness, polydipsia and polyuria have been observed; at present, her blood pressure, serum chemistry, and urine sediment are normal, but there is a marked failure in the renal concentration capacity, as well as marked sodium urinary losses. A percutaneous renal biopsy showed tubulo-interstitial fibrosis and edema with normal glomeruli. Case 2 is a girl with rheumatoid arthritis which appeared 3 years ago; for over one year, the patient was given 15 mg/day prednisone plus 1.5 g. acetylsalycilic acid. She was admitted to the hospital because her osteoarticular problem did not improve. Her blood pressure, blood chemistries and urinary sediment were also normal. LE tests were negative. Renal concentrating capacity was reduced and the renal biopsy showed tubular atrophy; there was intestinal edema and mononuclear infiltration. Chronic interstitial nephritis, secondary to analgesics is supported in both cases; polyuria and a marked defect of renal concentrating capacity are the earliest and most characteristic features. Normal urinary sediment is a common finding leading to erroneous assessment of a lack of renal involvement. Pathological lesions are located in the interstice of the renal medulla and sometimes in the papilla. Early arrest of analgesic ingestion may stop and even reverse the renal lesion and the renal insufficiency.

Patients with short familial stature (SFS) have a short body height, but their bone age is normal. The aim of this research was to assess dental maturity in 54 patients with SFS, aged from 4 to 15 1/2 years. Bone age was judged from radiographs of the left wrist, and dental age from orthopantomograms. Dental age was retarded in relation to chronological age and to bone age.
