Patients with COVID-19 present a broad spectrum of clinical presentation. Whereas hypoxaemia is the marker of severity, different strategies of management should be customised to five specific individual phenotypes. Many intubated patients present with phenotype 4, characterised by pulmonary hypoxic vasoconstriction, being associated with severe hypoxaemia with “normal” (>40 mL·cmH 2 O −1 ) lung compliance and likely representing pulmonary microvascular thrombosis. Phenotype 5 is often associated with high plasma procalcitonin and has low pulmonary compliance, Which is a result of co-infection or acute lung injury after noninvasive ventilation. Identifying these clinical phenotypes and applying a personalised approach would benefit the optimisation of therapies and improve outcomes.

BACKGROUND: We performed quantitative real-time polymerase chain reaction (Q-PCR) to monitor the evolution of Brucella melitensis DNA load from initial diagnosis through post-therapy follow-up in patients with brucellosis. METHODS: On the basis of real-time fluorometric quantification of PCR products, we used the ultra-rapid LightCycler system (Roche Diagnostics). We collected 180 peripheral blood samples from 18 patients with brucellosis. Analysis of bacterial DNA loads was performed for 2 groups: 11 patients who did not experience relapse and 7 patients who experienced relapse in the follow-up phase. RESULTS: Q-PCR was 100% specific for B. melitensis and showed an analytical sensitivity of 15 fg. Sensitivity of Q-PCR for both initial infections and relapses was 100%. There were no statistically significant differences between groups with respect to bacterial DNA load from initial diagnosis to the end of post-treatment follow-up (P > .05). Evolution of the bacterial DNA load throughout the treatment phase was similar among patients who relapsed and did not relapse. Despite positive response to treatment and a sharp decrease in bacterial DNA load after initiating therapy, the results of Q-PCR on finalizing treatment for 50% of the patients (7 from the relapse group and 2 from the nonrelapse group) were low-level positive. At the conclusion of follow-up, almost 40% of the patients (4 from the relapse group and 3 from the nonrelapse group), most of them asymptomatic, still maintained low bacterial DNA loads. CONCLUSIONS: Using Q-PCR techniques, we consistently detected B. melitensis DNA in the blood samples of patients with brucellosis throughout treatment and follow-up, despite apparent recovery from infection. These findings may have diagnostic, pathogenic, and therapeutic implications.

BACKGROUND: Knee osteoarthritis is a disease that affects a third of the population over 65 years of age, and it is increasingly becoming a motive for consultation and a source of pain and disability. The gold standard surgical treatment is a total knee arthroplasty; however, 15% to 30% of patients who have undergone surgery continue to experience pain and functional limitation. METHODS: A double-blind, randomized clinical study compared neurolysis using traditional radiofrequency (RF) to local anesthetic and corticosteroid block of the superolateral, superomedial, and inferomedial branches of the knee genicular nerves in patients who had total knee arthroplasty but still experience pain. RESULTS: Twenty-eight patients, 14 on each treatment arm, were followed for over a 1-year period. A reduction in pain and significant joint function improvement during the first 3 to 6 months was shown, with similar results using both techniques. No adverse effects were noted. An improvement in both disability and quality of life was observed, as well as a reduction in the need for analgesics in both treatment groups. CONCLUSIONS: Further clinical trials need to be undertaken, with a larger sample size, in order to demonstrate the efficacy of this technique and to detect the possible appearance of any long-term adverse effects.

Epididymoorchitis is a focal form of human brucellosis described in 2%-20% of patients with brucellosis. We assessed 59 cases of Brucella epididymoorchitis (BEO) between 1991 and 1999. The median age of patients was 34 years (range, 15-75 years). The onset of symptoms was acute in 46 patients (78%). Scrotal pain and swelling (100% of patients), fever (88%), and sweating (73%) were the most common symptoms. Brucella species was isolated from blood cultures in 41 patients (69%) and from epididymal aspiration in 4 patients. Treatment consisted of a combination of a doxycycline and an aminoglycoside (n=39) or rifampin (n=10); trimethoprim-sulfamethoxazole with rifampin (n=3); or trimethoprim-sulfamethoxazole as monotherapy (n=7). The median duration of therapy was 45 days (range, 21-90 days). The infections of 9 patients (15%) failed to respond to therapy, and 15 patients relapsed (25%). Three patients with necrotizing orchitis whose infections were unresponsive to antibiotics required an orchiectomy. In general, classical brucellosis therapy is adequate for BEO.

The complexity of the clinical management of neuroendocrine neoplasia (NEN) is exacerbated by limitations in imaging modalities and a paucity of clinically useful biomarkers. Limitations in currently available imaging modalities reflect difficulties in measuring an intrinsically indolent disease, resolution inadequacies and inter-/intra-facility device variability and that RECIST (Response Evaluation Criteria in Solid Tumors) criteria are not optimal for NEN. Limitations of currently used biomarkers are that they are secretory biomarkers (chromogranin A, serotonin, neuron-specific enolase and pancreastatin); monoanalyte measurements; and lack sensitivity, specificity and predictive capacity. None of them meet the NIH metrics for clinical usage. A multinational, multidisciplinary Delphi consensus meeting of NEN experts (n = 33) assessed current imaging strategies and biomarkers in NEN management. Consensus (>75%) was achieved for 78% of the 142 questions. The panel concluded that morphological imaging has a diagnostic value. However, both imaging and current single-analyte biomarkers exhibit substantial limitations in measuring the disease status and predicting the therapeutic efficacy. RECIST remains suboptimal as a metric. A critical unmet need is the development of a clinico-biological tool to provide enhanced information regarding precise disease status and treatment response. The group considered that circulating RNA was better than current general NEN biomarkers and preliminary clinical data were considered promising. It was resolved that circulating multianalyte mRNA (NETest) had clinical utility in both diagnosis and monitoring disease status and therapeutic efficacy. Overall, it was concluded that a combination of tumor spatial and functional imaging with circulating transcripts (mRNA) would represent the future strategy for real-time monitoring of disease progress and therapeutic efficacy.

BACKGROUND: Myocardial injury is a common finding in COVID-19 strongly associated with severity. We analysed the prevalence and prognostic utility of myocardial injury, characterized by elevated cardiac troponin, in a large population of COVID-19 patients, and further evaluated separately the role of troponin T and I. METHODS: This is a multicentre, retrospective observational study enrolling patients with laboratory-confirmed COVID-19 who were hospitalized in 32 Spanish hospitals. Elevated troponin levels were defined as values above the sex-specific 99th percentile upper reference limit, as recommended by international guidelines. Thirty-day mortality was defined as endpoint. RESULTS: A total of 1280 COVID-19 patients were included in this study, of whom 187 (14.6%) died during the hospitalization. Using a nonspecific sex cut-off, elevated troponin levels were found in 344 patients (26.9%), increasing to 384 (30.0%) when a sex-specific cut-off was used. This prevalence was significantly higher (42.9% vs 21.9%; P < .001) in patients in whom troponin T was measured in comparison with troponin I. Sex-specific elevated troponin levels were significantly associated with 30-day mortality, with adjusted odds ratios (ORs) of 3.00 for total population, 3.20 for cardiac troponin T and 3.69 for cardiac troponin I. CONCLUSION: In this multicentre study, myocardial injury was a common finding in COVID-19 patients. Its prevalence increased when a sex-specific cut-off and cardiac troponin T were used. Elevated troponin was an independent predictor of 30-day mortality, irrespective of cardiac troponin assay and cut-offs to detect myocardial injury. Hence, the early measurement of cardiac troponin may be useful for risk stratification in COVID-19.

The main source of vitamin D is synthesis in the skin during exposure to ultraviolet radiation. The existence of photoaggravated diseases and the increasing incidence of skin cancer have prompted recommendations to avoid the sun. Here, we study the status of vitamin D in a healthy population and its relation to their habits of sun exposure. To do so, we designed a cross-sectional study that included 177 healthy people. We analyzed parameters about demographic data, sun exposure, and protection habits and estimated vitamin D dietary intake. We performed blood tests to measure serum 25-hydroxyvitamin D [25(OH)D], calcium, phosphorus, and intact parathyroid hormone. Mean levels (± standard deviation) of 25(OH)D were 24.0 (± 8.5) ng/ml. Seventy-six percent of the population did not reach recommended levels of vitamin D (30 ng/ml), including 4.5% who were vitamin D deficient (< 10 ng/ml). Levels were higher in young people (P = 0.04) and those with more sun exposure (P = 0.04). Smoking was associated with an increased risk of hypovitaminosis D (odds ratio, 1.8; 95% confidence interval, 1.00-3.35). On the basis of our findings, we should consider the risk of hypovitaminosis when we recommend sun avoidance, especially in some risk groups, because the sun is the most important source of this vitamin.

BACKGROUND: Triclosan-coated sutures have been shown to reduce surgical-site infection (SSI) in emergent operation for fecal peritonitis. Barbed sutures provoke a homogeneous distribution of tension throughout the suture, implying better blood supply to the wound edges and healing. The aim of this study was to evaluate the effect, on SSI and evisceration, of using triclosan-coated and barbed sutures for fascial closure in patients undergoing emergent surgery. STUDY DESIGN: A prospective, randomized clinical trial was performed. Patients were randomized into 3 groups: those undergoing aponeurotic closure with triclosan-coated barbed suture (Stratafix Symmetric [Johnson & Johnson]), patients undergoing closure with triclosan-coated polydioxanone loop suture (PDS plus [Johnson & Johnson]), and patients undergoing closure with polydioxanone loop suture (PDS [Johnson & Johnson]). Primary investigated outcomes were SSI and evisceration rates during a follow-up period of 30 days. The primary analysis plan was based on a per-protocol approach. RESULTS: Incisional SSI was 6.4% (3 of 47) in the Stratafix Symmetric group, 8.9% (4 of 45) in the PDS plus group, and 23.4% (11 of 47) in PDS group (p = 0.03). The evisceration rate was 0% in Stratafix Symmetric, 8.9% (4 of 45) in PDS plus, and 12.8% (6 of 47) in PDS (p = 0.05). Median hospital stay was 4 days (range 2 to 14 days) in Stratafix Symmetric, 5 days (range 2 to 21 days) in PDS plus, and 8 days (range 2 to 60 days) in PDS (p = 0.012). The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) was associated with a lower risk of incisional SSI (p = 0.009), and the use of barbed suture was associated with a lower risk of evisceration (p = 0.019). Comparing Stratafix Symmetric with PDS plus, there were no significant differences in SSIs, but the evisceration rate was significantly higher in the PDS plus group (p = 0.036). CONCLUSIONS: The use of triclosan-coated sutures (Stratafix Symmetric and PDS plus) in emergent surgery reduces the incidence of incisional SSIs. The use of barbed sutures reduces the incidence of evisceration.

OBJECTIVE: The link between brain function and cardiovascular dynamics is an important issue yet to be elucidated completely. The insula is a neocortical brain area that is thought to have a cardiac chronotropic regulatory function, but its role in cardiac contractility is unknown. We aimed to analyze the variability in heart rate and cardiac contractility after functional activation of different insular regions through direct electrical stimulation (E-stim) in humans. METHODS: This was an observational, prospective study, including patients admitted for stereo-electroencephalographic recording because of refractory epilepsy, in whom the insular cortex was implanted. Patients with anatomical or electrophysiological insular abnormalities and those in whom E-stim produced subjective symptoms were excluded. Variations in heart rate (HR), stroke volume (SV), and cardiac output (CO) were analyzed during insular E-stim and compared with control E-stim of non-eloquent brain regions and sham stimulations. RESULTS: Ten patients were included, 5 implanted in the right insula (52 E-stim) and 5 in the left (37 E-stim). Demographic and clinical characteristics of both groups were similar. E-stim of both right and left insulas induced a significant decrease of the CO and HR, and an increase of the SV. E-stim of control electrodes and sham stimulations were not associated with variations in cardiac function. Blood pressure and respiratory rate remained unaltered. INTERPRETATION: Our results suggest a direct chronotropic and inotropic cardiac depressor function of the right and left insulas. The evidence of an insular direct cardiac regulatory function might open a path in the prevention or treatment of heart failure, arrhythmias, and sudden unexpected death in epilepsy.

The development of novel culture-independent techniques of microbial identification has allowed a rapid progress in the knowledge of the nasopharyngeal microbiota and its role in health and disease. Thus, it has been demonstrated that the nasopharyngeal microbiota defends the host from invading pathogens that enter the body through the upper airways by participating in the modulation of innate and adaptive immune responses. The current COVID-19 pandemic has created an urgent need for fast-track research, especially to identify and characterize biomarkers to predict the disease severity and outcome. Since the nasopharyngeal microbiota diversity and composition could potentially be used as a prognosis biomarker for COVID-19 patients, which would pave the way for strategies aiming to reduce the disease severity by modifying such microbiota, dozens of research articles have already explored the possible associations between changes in the nasopharyngeal microbiota and the severity or outcome of COVID-19 patients. Unfortunately, results are controversial, as many studies with apparently similar experimental designs have reported contradictory data. Herein we put together, compare, and discuss all the relevant results on this issue reported to date. Even more interesting, we discuss in detail which are the limitations of these studies, that probably are the main sources of the high variability observed. Therefore, this work is useful not only for people interested in current knowledge about the relationship between the nasopharyngeal microbiota and COVID-19, but also for researchers who want to go further in this field while avoiding the limitations and variability of previous works.

OBJECTIVES: To assess whether clinical trials published in the orthodontic literature comply with the Consolidated Standards of Reporting Trials (CONSORT) statement, and whether compliance has changed over time. DESIGN: Retrospective study. SAMPLE: Clinical trials published in four orthodontic journals (American Journal of Orthodontics and Dentofacial Orthopedics, Angle Orthodontist, European Journal of Orthodontics, and Journal of Orthodontics) at three time points [1995/6 (pre-CONSORT), 2000/1 (post-CONSORT) and 2005/6 (post revised-CONSORT)]. METHODS: Trials were scored using a 36-point checklist developed from the CONSORT statement. Each item on the checklist was scored as either included, not included, or not applicable if the trial design did not allow its inclusion. The proportion of trials describing randomization, allocation concealment, and blinding was also calculated. The mean scores were compared between time points and between journals. RESULTS: A total of 151 reports were included. The mean score was 41·5% (SD 10·3). The mean post-CONSORT score was higher than the pre-CONSORT score (P = 0·01; WMD, 5·73; 95% CI, 1·64-9·82), and the mean post revised-CONSORT was also higher than the pre-CONSORT score (P = 0·01; WMD, 4·44; 95% CI, 1·02-7·87). At the post revised-CONSORT time point, the mean score in the journals which had adopted the CONSORT statement was higher than for those which had not (P<0·001; chi square, 17·78; df = 3). Reporting of randomization, allocation concealment and blinding was inadequate at all three time points. CONCLUSIONS: The reporting of clinical trials in the orthodontic literature has improved since the publication of the CONSORT statement, particularly in journals which have adopted the statement. However, the reporting of randomization, allocation concealment and blinding remains inadequate.

Low serum 25-hydroxyvitamin D [25(OH)D] levels have been associated with increased prevalence of cardiovascular diseases. A possible relation between lipids and 25(OH)D might explain this association. This investigation aimed to determine the association between vitamin D and cholesterol, as well as the influence of statins on this association. This was a cross-sectional population-based study with 177 subjects aged 18-84 years. We collected demographics and data on sun exposure, sun protection habits, current medication including lipid-lowering drugs, and estimated vitamin D intake. Serum measurements included levels of 25(OH)D, parathyroid hormone (PTH), calcium, phosphorus, total cholesterol, high-density lipoprotein (HDL) cholesterol, low-density lipoprotein (LDL) cholesterol, triglycerides, and fasting glucose. The mean 25(OH)D level was 24 ± 9 ng/ml. Young age (P = 0.04) and spending more than 1 h outdoors (P = 0.04) were independently associated with higher 25(OH)D levels. The 25(OH)D concentrations correlated negatively with total cholesterol (P = 0.01) and LDL cholesterol (P = 0.04) levels. The adjusted OR for total cholesterol > 200 mg/ml was 2.8 (range, 1.1-7.5). Receiving statins was associated with higher 25(OH)D levels (P = 0.04). In conclusion, this study supports an association between 25(OH)D levels and cholesterol. Further studies are required to explain this association.

One focus of agricultural development is climate smart agricultural technologies and practices (CSA). Development practitioners invest in scaling these to have wider impact. Ineffective targeting stymies CSA’s contribution to poverty reduction by excluding many of the poor and/or including those for whom agriculture is not a pathway out of poverty. This viewpoint proposes the need to recognise differentiated livelihood pathways within smallholder agriculture, linked to farmers’ differential capacity to engage in climate risk management. A farmer and livelihoods typology provides a framework to improved targeting of CSA and to identifying where alternative interventions, such as social protection, are more appropriate.

Interest in the coronavirus disease 2019 (COVID-19) has progressively decreased lately, mainly due to the great effectivity of vaccines. Furthermore, no new severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variants able to circumvent the protection of these vaccines, while presenting high transmissibility and/or lethality, have appeared. However, long COVID has emerged as a huge threat to human health and economy globally. The human microbiota plays an important role in health and disease, participating in the modulation of innate and adaptive immune responses. Thus, multiple studies have found that the nasopharyngeal microbiota is altered in COVID-19 patients, with these changes associated with the onset and/or severity of the disease. Nevertheless, although dysbiosis has also been reported in long COVID patients, mainly in the gut, little is known about the possible involvement of the microbiota in the development of this disease. Therefore, in this work, we aim to fill this gap in the knowledge by discussing and comparing the most relevant studies that have been published in this field up to this point. Hence, we discuss that the relevance of long COVID has probably been underestimated, and that the available data suggest that the microbiota could be playing a pivotal role on the pathogenesis of the disease. Further research to elucidate the involvement of the microbiota in long COVID will be essential to explore new therapeutic strategies based on manipulation of the microbiota.

BACKGROUND: The main vitamin D source is exposure to ultraviolet radiation, which aggravates cutaneous lupus erythematosus (CLE). OBJECTIVES: The aims of this study were to identify variables associated with lower serum 25-hydroxyvitamin D [25(OH)D] levels in CLE patients and assess the effect of vitamin D restoration on disease severity. METHODS: Vitamin D status in 60 CLE patients and 117 apparently healthy subjects was compared. We recommended oral vitamin D3 to 27 CLE patients. After one year of treatment, changes in disease severity were assessed and compared to 25 untreated CLE patients. Disease severity was measured by the Cutaneous Lupus Erythematosus Disease Area and Severity Index (CLASI), number of exacerbations, duration of active lesions and patient assessment. RESULTS: Presence of CLE raised the odds of having vitamin D deficiency (OR 3.47, 95% CI 1.79-6.69). Increasing age and disease duration were associated with higher odds of having vitamin D deficiency. After a one-year follow-up, disease activity improved in the treatment group (CLASI A 2.7 ± 2.9 vs. 0.9 ± 1.4) (p = 0.003), as confirmed by the patient assessment (p = 0.01). CONCLUSIONS: Vitamin D inadequacy is more prevalent in CLE participants than in healthy controls. Treating vitamin D insufficiency is associated with improved disease severity according to physician and patient assessments.

= .019). This is the first multicenter study in which an effort was carried out to adjust the results of laboratory tests measured with different methodologies to guarantee their comparability. We reported a comprehensive information about characteristics in a large cohort of hospitalized COVID-19 patients, focusing on the analytical features. Our findings may help to identify patients early at a higher risk for an adverse outcome.

Conocer la adherencia al tratamiento en pacientes que inician fármacos antidepresivos y analizar los factores asociados al incumplimiento, tanto clínicos como sociodemográficos. Estudio observacional longitudinal prospectivo. Consultas de atención primaria y de salud mental de tres áreas sanitarias de Castilla-La Mancha. Un total de 185 pacientes mayores de 18 años que iniciaron tratamiento antidepresivo. Cumplimiento terapéutico (test Haynes-Sackett, Morisky-Green, recuento de comprimidos y MEMS), efectos adversos, intensidad de los síntomas depresivos, características sociodemográficas y otras características relacionadas con los antidepresivos o con los participantes. Tras 6 meses del inicio del tratamiento antidepresivo, el 46,9% (IC 95%: 36,5-57,3) mostró un cumplimiento inadecuado mediante el método de recuento de comprimidos, y el 28,6% (IC 95%: 19,1-38,0) con el cuestionario de Morisky-Green. A los 15 días la falta de adherencia fue del 48,5% (IC 95%: 40,6-56,4) y del 33,5% (IC 95%: 26,1-41,0), respectivamente. El 38,4% (IC 95%: 31,1-45,7) manifestó algún efecto secundario durante el seguimiento. Mediante un modelo de riesgos proporcionales de Cox las variables relacionadas con incumplimiento fueron menor edad, nivel de instrucción inferior a enseñanza secundaria, prestación farmacéutica como pensionista, no recibir tratamiento psicoterápico, consumir menor número de fármacos no antidepresivos y frecuentación ≤ 3 visitas al médico de familia los 3 meses previos al inicio del estudio. El incumplimiento del tratamiento antidepresivo es elevado en atención primaria desde las primeras semanas tras iniciarlo. Constituyen factores condicionantes del mismo los relacionados con características sociodemográficas y con otras características de los pacientes como tipo de financiación de prestación farmacéutica y frecuentación a las consultas. To know the adherence to treatment in patients who initiate antidepressant drugs and to analyze the determinant factors of non-compliance, so much clinical as sociodemographic. Prospective longitudinal observational study. Primary Health Care and Mental Health Surgeries of three Castilla-La Mancha Areas. 185 adults patients who were started in antidepressant treatment were evaluated. Treatment adherence (test Haynes-Sackett, test Morisky-Green, count of tablets and MEMS), adverse effects, intensity of depressive symptoms, sociodemographic characteristics and other characteristics related to antidepressants or participants. After 6 months of beginning antidepressing treatment, 46.9% (95% IC: 36.5-57.3) showed an inadequate fulfilment by pill count method and 28.6% (95% IC: 19.1-38.0) with Morisky-Green's questionnaire. To 15 days the lack of adherence was 48.5% (95% IC: 40.6-56.4) and of 33.5% (95% IC: 26.1-41.0). The 38.4% (95% IC: 31.1-45.7) demonstrated some side effect during the follow-up. Using proportional risk model of Cox the variables related to compliance were: younger age, level of instruction lower than secondary studies, free medicines for pensioner, no psychotherapeutic treatment, consume a fewer antidepressants drugs and a frequency ≤ 3 visits to the family doctor 3 months previous to the study. The non-compliance of antidepressant treatment in primary care is high from the first weeks after initiating it. The conditioning factors are related to sociodemographic characteristics and other patient characteristics as type of financing of pharmaceutical benefit and frequentness at primary care.

Eighteen cases of amelia in the Spanish Collaborative Study of Congenital Malformations (ECEMC) were analyzed epidemiologically. Prevalence at birth was 0.15 per 10,000 newborn infants, which is not different from that reported by other authors. Affected females outnumbered males. When compared with the control group, a lower birth weight, shorter gestation, lower placental weight, greater frequency of single umbilical artery, noncephalic presentation at birth, and more frequent maternal vaginal bleeding were observed in amelia cases. There were no significant variations of parental age. None of these patients was exposed to known teratogens, apart from 1 born to a diabetic mother; 3 patients had a genetic condition. Comparison of these variables with other studies is difficult because there is only one study that specifically analyzed amelia. Our data together with previous observations suggest that the genetic basis of amelia might be more important than has been considered previously.

Se han categorizado las 1336 especies y subespecies de la fauna ibérica de Carabidae, usando los corotipos propuestos por Vigna Taglianti et al. (1992), los cuales se han completado con algunos otros adicionales. La Península Ibérica destaca entre las diversas regiones europeas y circunmediterráneas por la elevada proporción de elementos endémicos (43,1%). La antigüedad y estabilidad de la mitad norte peninsular, el aislamiento de la región, los plegamientos alpinos y la abundancia de cuevas, son factores que probablemente han contribuido a su singularidad faunística. Los elementos de amplia distribución predominan a la escala regional; las proporciones de endemismos son mayores hacia el Norte y en las zonas de montaña; la de los elementos mediterráneos se incrementa hacia el Sur, al contrario de lo que ocurre con los elementos europeos. La adaptación al régimen climático mediterráneo y la dispersión son dos de los factores que probablemente causan estos patrones. La Península es pobre en elementos afrotropicales, posiblemente debido al aislamiento causado por la barrera natural del Sahara. Las Islas Baleares tienen altas proporciones de elementos de amplia distribución y mediterráneos, lo que sugiere el papel relevante de la dispersión en la colonización de las islas. La proporción de endemismos de Mallorca (7,8%) es intermedia entre la de Cerdeña y Sicilia; a pesar de su aislamiento las Baleares son de tamaño pequeño y tienen un abundancia moderada de medios favorables para la especiación, como ocurre con las cuevas, lo que explica que la mayoría de los endemismos se encuentren en zonas abiertas de baja altitud.
