Asprosin levels in patients with type 2 diabetes mellitus, metabolic syndrome and obesity: A systematic review and meta-analysis.

BACKGROUND & AIMS: Asprosin is a promising candidate for novel treatments for metabolic-endocrine disorders. The objective of this systematic review and meta-analysis was to consolidate the existing evidence regarding asprosin levels in patients diagnosed with type 2 diabetes (T2D), metabolic syndrome (MetS), and obesity. METHODS: Scopus, Embase, PubMed, Ovid/Medline, and Web of Science were systematically searched without restrictions. We only used the standardized mean differences (SMD) with their 95 % confidence intervals (95 % CI) as the effect measure. A random-effects model (DerSimonian and Laird method) was used for the meta-analysis. Risk of bias was assessed with the Newcastle-Ottawa Scale and Newcastle-Ottawa Scale for Cross-Sectional Studies. RESULTS: Twenty-six studies (n = 3,787) were included in the meta-analysis. Participants with T2D had higher asprosin values than those without T2D (SMD: 1.64; 95 % CI: 1.08-2.21; I2 = 97 %). Patients with MetS had higher asprosin levels compared to those without MetS (SMD: 0.99; 95 % CI: 0.34-1.64; I2 = 96 %). Patients with obesity had higher asprosin levels than participants without obesity (SMD: 1.49; 95 % CI: 0.23-2.76; I2 = 98 %). CONCLUSIONS: Asprosin is significantly higher in patients with either T2D, MetS, or obesity, compared with controls.

Proof of concept for a nonadditive stochastic model of supercooled liquids.

The recently proposed nonadditive stochastic model (NSM) offers a coherent physical interpretation for diffusive phenomena in glass-forming systems. This model presents nonexponential relationships between viscosity, activation energy, and temperature, characterizing the non-Arrhenius behavior observed in supercooled liquids. In this work, we fit the NSM viscosity equation to experimental temperature-dependent viscosity data corresponding to 25 glass-forming liquids and compare the fit parameters with those obtained using the Vogel-Fulcher-Tammann (VFT), Avramov-Milchev (AM), and Mauro-Yue-Ellison-Gupta-Allan (MYEGA) models. The results demonstrate that the NSM provides an effective fitting equation for modeling viscosity experimental data in comparison with other established models (VFT, AM, and MYEGA), characterizing the activation energy in fragile liquids, presenting a reliable indicator of the degree of fragility of the glass-forming liquids.

Mexican consensus about surgical treatment in early-stage cervicouterine cancer.

Introduction: Cervical cancer is a public health problem in our country and worldwide. Less than 25% of cases are diagnosed in the early stages, where survival is more remarkable than 90% at five years. Here, we review surgical treatment in the early stages of cervical cancer. Methodology: A literature review was carried out in the MEDLINE database. The search was mainly limited to the English language, with priority given to systematic reviews with or without meta-analysis and randomized studies. However, only retrospective or observational evidence was found for some topics. Results: The standard treatment for early-stage cervical cancer is hysterectomy, and its radical nature will depend on the tumor size, lymphovascular permeation, and tumor-specific prognostic factors. Furthermore, the type of surgery (hysterectomy or trachelectomy) will rely on the patient's desire to preserve fertility. Nodal evaluation is indicated as part of the treatment from stage IAI with PLV. However, the sentinel lymph node is more relevant in the treatment. The incidental finding of cervical cancer after a hysterectomy requires a multidisciplinary evaluation to determine the therapeutic approach. Less radical surgery has been described as oncologically safe in low-risk groups. Conclusion: Surgical treatment in its early stages has evolved in recent decades, making it more individualized and seeking less morbidity in patients without compromising their survival.

Histoplasmosis Beyond Human Immunodeficiency Virus (HIV): Clinical Characteristics and Outcomes in a Non-HIV Population.

Histoplasmosis is an endemic and invasive mycosis caused by Histoplasma capsulatum. We conducted a retrospective study comparing immunosuppressed patients without human immunodeficiency virus (HIV) with a historical cohort of people with HIV and histoplasmosis. We included 199 patients with proven or probable histoplasmosis, of which 25.1% were people without HIV. Diabetes mellitus, chronic kidney disease, hematologic neoplasms, rheumatologic diseases, and transplantations were more frequent among people without HIV (P < .01). Forty-four percent of immunocompromised patients without HIV died within the first 6-week period following their diagnosis. A high suspicion index for histoplasmosis should be kept in immunosuppressed patients.

Fungal infections in patients after recovering from COVID-19: a systematic review.

Background and aims: The presence of fungal infections has been described in patients after recovering from COVID-19. This study aims to conduct a systematic review of studies that reported fungal infections (Mucor spp., Pneumocystis jirovecii, or Aspergillus spp.) in adults after recovering from COVID-19. Methods: We performed a systematic review through PubMed, Web of Science, OVID-Medline, Embase, and Scopus. The study selection process was performed independently and by at least two authors. We performed a risk of bias assessment using the Newcastle-Ottawa Scale for cohort and case-control studies, and the Joanna Briggs Institute's Checklists for Case Series and Case Reports. Results: The systematic search found 33 studies meeting all inclusion criteria. There was a total population of 774 participants, ranging from 21 to 87 years. From them, 746 developed a fungal infection. In 19 studies, Mucor spp. was reported as the main mycosis. In 10 studies, P. jirovecii was reported as the main mycosis. In seven studies, Aspergillus spp. was reported as the main mycosis. Regarding the quality assessment, 12 studies were classified as low risk of bias and the remaining studies as high risk of bias. Conclusion: Patients' clinical presentation and prognosis after recovering from COVID-19 with fungal infection differ from those reported patients with acute COVID-19 infection and those without COVID-19 infection.

Medial tab-type fasciocutaneous flap as an alternative for the management of soft tissue defects of the leg. / Colgajo fasciocutáneo tipo lengüeta medial como alternativa para el manejo de defectos de tejidos blandos en la pierna.

BACKGROUND: Selecting the right technique for lower limb soft tissue reconstruction is a therapeutic challenge. Despite having several reconstruction options, it's important to choose a technique that is effective and with the least possible donor site morbidity. OBJECTIVE: Demonstrate the therapeutic efficacy of the medial tab flap in soft tissue reconstruction on the leg, compared to conventional flaps. MATERIALS AND METHODS: Cohort study matched by age. 64 patients with soft tissue defects were selected and according to the intervention divided in: group 1)medial tab flap, and group 2)conventional flaps (sural, soleus, gastrocnemius) followed up to one year postoperatively. OUTCOME VARIABLES: surgical time in minutes, healing, healing time in days, complications. RESULTS: The patients who underwent surgery with medial tab flap and with conventional flaps healed completely. The healing time was 16.2±11.2 days in the tab flap and 16.1±11.2 days in conventional flaps, no statistically significant differences were found between the groups (P=.89). The surgical time for tab flaps was 225.2±117.8minutes, and 191.3±117.2minutes for the comparison flaps (P=.65), there were no statistically significant differences. There were no complications in the medial tab flaps. CONCLUSION: The findings suggest that the medial tab flap technique is as effective as the conventional flap technique, with complete flap survival and healing, and without any major complications in this studied group.

Choice of molecular marker influences spatial patterns of phylogenetic diversity.

Spatial patterns of phylogenetic diversity (PD) are increasingly becoming relevant for conservation decisions. PD measures are based on phylogenies estimated from molecular data. This paper addresses the question of how different molecular markers impact PD spatial patterns. We first conducted a simple simulation to explore the effect of deep and shallow changes in topology (simulating variations in molecular markers), using ultrametric and non-ultrametric trees, and then used a dataset of Chilean flora with four sets of markers to assess potential differences in spatial patterns of PD ranks using different markers and types of trees. The simulation consistently showed that the difference in PD rank was lower for ultrametric trees than for phylograms. A similar trend was observed using the Chilean flora dataset, with among-markers variability in spatial patterns of the PD metrics lower for ultrametric than for non-ultrametric trees, depicted as top 2.5 and 5% hotspots. Frequency distribution of PD values differed among markers as well, with this variation less apparent for ultrametric trees. We conclude that the choice of markers impacts spatial patterns of PD, and these results vary more strongly for phylograms, suggesting that ultrametric trees are more robust to the choice of marker.

Caregiver-centred empowerment for families raising autistic children: A qualitative case study from Argentina.

LAY ABSTRACT: Caregivers of children with developmental disabilities, including autism, often struggle to access services, information and resources in Argentina. Little is known about how caregivers can be empowered to support their children as they wish to in the Argentinian setting. We spoke with 32 people online to understand existing and potential practices of supporting caregivers. The people we spoke with included caregivers, health service providers, non-governmental organisations' representatives providing services or technical support, special education teachers and policy representatives. Participants said that poverty, and inequalities in accessing support, impact how caregivers can support their children. They mentioned examples that help caregivers feel empowered, such as peer support groups and caregiver training. Many caregivers spoke about how they became advocates for their children and how they developed initiatives such as advocacy campaigns and well-being support groups. Caregivers in Argentina may be empowered in various ways, and the following strategies can improve empowerment: strengthening collaboration between professionals and caregivers; focusing on caregiver mental health; and addressing the profound impact of poverty on the quality of life of families.

Borolatonin limits cognitive deficit and neuron loss while increasing proBDNF in ovariectomised rats.

BACKGROUND: Borolatonin is a potential therapeutic agent for some neuronal diseases such as Alzheimer's disease (AD). Its administration exerts ameliorative effects such as those induced by the equimolar administration of melatonin in behavioral tests on male rats and in neuronal immunohistochemistry assays. OBJECTIVE: In this study, motivated by sex differences in neurobiology and the incidence of AD, the ability of borolatonin to induce changes in female rats was assessed. METHODS: Effects of borolatonin were measured by the evaluation of both behavioral and immunohistopathologic approaches; additionally, its ability to limit amyloid toxicity was determined in vitro. RESULTS: Surprisingly, behavioral changes were similar to those reported in male rats, but not those evaluated by immunoassays regarding neuronal survival; while pro-brain-derived neurotrophic factor (BDNF) immunoreactivity and the limitation of toxicity by amyloid in vitro were observed for the first time. CONCLUSION: Borolatonin administration induced changes in female rats. Differences induced by the administration of borolatonin or melatonin could be related to the differences in the production of steroid hormones in sex dependence. Further studies are required to clarify the possible mechanism and origin of differences in disturbed memory caused by the gonadectomy procedure between male and female rats.

Factors Associated with Parametrial Involvement in Endometrial Carcinoma in Patients Treated with Radical Hysterectomy.

INTRODUCTION: Describe factors associated with parametrial involvement, and how these factors modify the prognosis of patients with endometrial carcinoma treated with radical hysterectomy. METHODS: Observational study in which categorized patients according to those with and without parametrial involvement. A descriptive analysis and comparative analysis were performed for associations between parametrial spread and clinical, surgical, and pathology variables. RESULTS: We analyzed 85 patients, which 18 (21%) had parametrial involvement. Pathology factors associated with parametrial involvement were the endometrioid subtype, grade 3, and variants of poor prognosis (odds ratio (OR) 3.41, 95% CI 1.09-10.64; P = 0.035), myometrial invasion of over 50% (OR 7.76, 95% CI 1.65-36.44; P = 0.009), serosal involvement (OR 17.07, 95% CI 3.87-75.35; P < 0.001), ovarian metastasis (OR 5.15, 95% CI 1.36-19.46; P = 0.016), positive peritoneal cytology (OR 3.9, 95% CI 1.04-14.77; P = 0.044), and lymph node metastasis (OR 3.4; 95% CI 1.16-9.97; P = 0.026). Five-year disease-free survival was 74% (95% CI 57.4-85.4) for the group without parametrial spread and 50.8% (95% CI 22.7-73.4) for the group with parametrial spread (P = 0.001). Similarly, 5-year overall survival was 85.2% (95% CI 67.9-93.6) for the group without parametrial spread and 47.5% (95% CI 8.1-80.2) for the group with parametrial spread (P = 0.002). CONCLUSION: Factors associated with parametrial involvement were histologies of poor prognosis, tumors affecting uterine serosa, cervix, or spread beyond the uterus. Additionally, parametrial involvement directly affects prognosis by reducing overall survival, disease-free survival and increasing odds for recurrence.

Preeclampsia pravastatin early VS late treatment: Effects on oxidative stress and vascular reactivity.

Early diagnosis and efficient treatment of preeclampsia remains a medical challenge and etiological factors converge in a deficient placentation that triggers oxidative stress. There is evidence that statins show antioxidant effects that can improve endothelial function without adverse perinatal effects. We aimed to compare early vs. late pravastatin treatment on the oxidative stress and cardiovascular features of an experimental model of preeclampsia. Female Wistar rats were randomly divided into preeclampsia phenotype rats (PEP) developed by sub renal aortic coarctation (SRAC) and healthy pregnant rats (C). Each group received pravastatin (5 mg/Kg) p.o. either for one week before and during the first week or during the last two weeks of gestation. Blood pressure was determined using the plethysmographic method. Phenylephrine (Phe)-induced contractility was evaluated in isolated thoracic and abdominal aortic rings with or without endothelium. Blood samples were obtained to determine anion superoxide concentration as indicator of NADPH activity. Two-way ANOVA and Bonferroni post hoc tests were used to define statistical significance. Early or late pravastatin treatment decreased hypertension of PEP animals but did not change BP of the healthy pregnant group. Thoracic and abdominal aorta from PEP rats showed increased contractility that was reverted by pravastatin early treatment in endothelium intact rings. Pravastatin did not significantly change contractility neither in the thoracic nor in the abdominal aorta segments from healthy pregnant control rats (C), and decrease anion superoxide concentration by NADPH activity. We conclude pravastatin can improve both blood pressure and endothelium-dependent Phe-induced contractility in an experimental model of preeclampsia by reducing oxidative stress.

2-Aminoethyl Dihydrogen Phosphate (2-AEH2P) Associated with Cell Metabolism-Modulating Drugs Presents a Synergistic and Pro-Apoptotic Effect in an In Vitro Model of the Ascitic Ehrlich Tumor.

The progression and maintenance of cancer characteristics are associated with cellular components linked to the tumor and non-cellular components with pro-tumoral properties. Pharmacological association with antagonists of the cellular components of the tumor, such as anti- and pro-apoptotic drugs, represents a novel adjuvant strategy. In this study, the antiproliferative, pro-apoptotic, and pharmacological effects of the combination of monophosphoester 2-AEH2P with Simvastatin, Coenzyme Q10, the chemotherapeutic drug paclitaxel, and colony-stimulating factor (GM-CSF) were evaluated. Tests were conducted to determine cytotoxic activity using the MTT method, cell cycle phases, and fragmented DNA by flow cytometry, mitochondrial membrane potential, expression of cell markers Bcl2, TNF-α/DR-4, Cytochrome c, caspase 3, and P53, and analysis of drug combination profiles using Synergy Finder 2.0 Software. The results showed a synergistic effect among the combinations, compared to individual treatments with the monophosphoester and other drugs. In addition, there was modulation of marker expression, indicating a pro-apoptotic and immunomodulatory effect of 2-AEH2P. Pharmacological analysis revealed that tumor cells treated with GM-CSF + 2-AEH2P exhibited a synergistic effect, while groups of tumor cells treated with paclitaxel, Coenzyme Q10, and Simvastatin showed additive effects. Furthermore, treatment with the paclitaxel + 2-AEH2P combination (12 h) resulted in a significant reduction in mitochondrial membrane potential. Pharmacological combinations for normal cells did not exhibit deleterious effects compared to mammary carcinomatosis tumor (EAT) cells.

Interpersonal and Community-Level Influences Across the PrEP Cascade Among Young Adult Latinx Men who Have Sex with Men Living in a US-Mexico Border Region: A Qualitative Study.

Latinx men who have sex with men (MSM) are an at-risk population for new HIV diagnoses. Pre-exposure prophylaxis (PrEP) is a suite of biomedical approaches to prevent HIV infection. Latinx MSM are less likely to take PrEP compared to non-Latinx White MSM. This qualitative study identified interpersonal- and community-level barriers and facilitators of PrEP among young adult Latinx MSM. Using stratified purposeful sampling, 27 Latinx men, ages 19-29 years and living in a US-Mexico border region, completed self-report demographic surveys and participated in semi-structured in-depth interviews assessing barriers and facilitators to PrEP. Directed content analysis was used to identify both a priori and emerging themes. Most participants reported that other people, including peers, friends, partners, and health care providers were both supportive and discouraging of PrEP use. Participants' intersectional identities as members of both Latinx and LGBTQ+ (Lesbian, Gay, Bisexual, Transgender, Queer) communities both hindered and facilitated PrEP use.

Optimization of Plasmodium vivax infection of colonized Amazonian Anopheles darlingi.

Obtaining Plasmodium vivax sporozoites is essential for in vitro culture of liver stage parasites, not only to understand fundamental aspects of parasite biology, but also for drug and vaccine development. A major impediment to establish high-throughput in vitro P. vivax liver stage assays for drug development is obtaining sufficient numbers of sporozoites. To do so, female anopheline mosquitoes have to be fed on blood from P. vivax-infected patients through an artificial membrane-feeding system, which in turns requires a well-established Anopheles colony. In this study we established conditions to provide a robust supply of P. vivax sporozoites. Adding a combination of serum replacement and antibiotics to the membrane-feeding protocol was found to best improve sporozoite production. A simple centrifugation method appears to be a possible tool for rapidly obtaining purified sporozoites with a minimal loss of yield. However, this method needs to be better defined since sporozoite viability and hepatocyte infection were not evaluated.

Adult Diaphorina citri Biocontrol Using Hirsutella citriformis Strains and Gum Formulations.

Hirsutella citriformis Speare is the only entomopathogenic fungus that has been applied to control the hemipteran Diaphorina citri Kuwayama. However, the use of available commercial products under field conditions is limited due to conidia's shelf life and short environmental persistence. We have previously reported the citrus psyllid D. citri adults' biocontrol potential using H. citriformis strains. The aim of the present study was to evaluate different formulations based on H. citriformis (OP-Hir-3, OP-Hir-10, and OP-Hir-12 strains) conidia and gums as additives to improve D. citri adults' biocontrol, under laboratory, greenhouse, and field conditions, using Hirsutella gums as conidia stabilizers to improve their viability under environmental drought conditions and as insecticide. Laboratory bioassay results showed that the highest (p < 0.05) D. citri mortality was achieved using FOP-Hir-10GH (63.5%), followed by the Hirsutella gum control (42.2%). Under greenhouse conditions, adults' mortality reached up to 84.6% with FOP-Hir-12 and 49.0% with Hirsutella gum. In addition, we applied H. citriformis formulations under field conditions in a commercial citrus grove located in Tecomán, Colima, México, at 21.5 °C and 73.3% relative humidity (RH) in March and 25.7 °C and 72.5% RH in October 2022 and observed 67.3% and 94.0% mortality of D. citri adults, respectively. Hirsutella gum alone showed significant insecticidal activity against D. citri adults. In conclusion, this study demonstrated that Hirsutella gum functioned as additive to H. citriformis conidia formulations, improving D. citri adults' mortality and showing potential for this pest biocontrol in citrus orchards.

Impact of Normal and Overweight Pregnancy in GLUT4 and Glucose-Dependent Vascular Contractility.

INTRODUCTION: Obesity during pregnancy can contribute to hypertensive complications through changes in glucose utilization. We investigated the impact of vascular glucose uptake, GLUT4 density, and endothelium on agonist-induced vasoconstriction in the aortas of overweight pregnant rats. METHODS: Isolated aortic rings with or without endothelium from pregnant or nonpregnant rats fed a standard (SD) or hypercaloric diet (HD) were contracted with phenylephrine or serotonin (10-9 to 10-4M) using standard (11 mm) or without (0 mm) glucose Krebs solution. GLUT4 density in the aortas was measured using the en face method. RESULTS: Aortas from overweight pregnant animals (PHD) showed increased Phe-induced vasoconstriction (p < 0.05 vs. pregnant standard diet [PSD]), which was endothelium-independent. The contraction decreased significantly in the absence of glucose. In contrast, vessels from pregnant SD rats maintained their contraction in glucose-free Krebs solution. 5-HT increases PHD aortic contraction only in the absence of glucose. The fetal aortas from PHD mothers showed blunted vasoconstriction. Overweight significantly reduced GLUT4 expression in maternal and fetal aortas (p < 0.05 vs. PSD). CONCLUSIONS: Aortic contractility is independent of glucose uptake during healthy pregnancy. In contrast, overweight pregnancy increases contractility. This increase depends directly on smooth muscle glucose uptake and inversely on GLUT-4 density. The increased contraction observed in the vasculature of overweight mothers was inverted in the fetal aortas.

Factors associated with emergency room readmission after elective surgery for ovarian carcinoma.

BACKGROUND: Hospital readmission is a quality metric of hospital care and has been studied in ovarian carcinoma, but its evaluation has several limitations. Also, emergency room (ER) readmission is considered an adverse effect because it represents patient costs. Therefore, our objective was to determine the rate of ER readmission, its causes, and associated factors. METHODS: A retrospective study of 592 patients with ovarian carcinoma who underwent upfront surgery, neoadjuvant therapy, or surgery for recurrent disease. An analysis of factors associated with ER readmission, hospital readmission, and surgical complications was performed, including multivariate analysis to assess for case-mix factors. RESULTS: Of 592 patients, the median age was 51 years, and the predominant type of treatment was the neoadjuvant approach (52.9%); 46% underwent upfront surgeries and six surgeries for recurrence. The ratio to ER readmission was 11.8% (70 patients), of whom 12 patients were admitted more than once. The factors associated with ER readmission were prolonged surgery, intraoperative bleeding, extended hospital stay, the time of the day when the surgery was performed, and post-surgical complications. The hospital readmissions were 4.2%, and the overall morbidity was 17.6%. In the multivariate analysis, the only factor associated with ER readmission was the presence of surgical complications (OR = 39.01). The factors independently associated with hospital readmission were the entrance to the intensive care unit (OR = 1.37), the presence of surgical complications (OR = 2.85), and ER readmission (OR = 1.45). CONCLUSION: ER readmission is an adverse event representing the presence of symptoms/complications in patients. Evaluating the ER readmission independently of the readmission to the hospital is critical because it will allow modifying medical care behaviors to prevent patients from unnecessarily returning to the hospital after a hospital discharge to manage preventable medical problems.

Seroprevalence of human toxocariasis in Latin America and the Caribbean: a systematic review and meta-analysis.

Introduction: The current study aimed to quantitatively synthesize available evidence regarding the seroprevalence of human toxocariasis in Latin America and the Caribbean. Methods: A systematic research involving six electronic databases was conducted using a research strategy that combined MeSH terms with free terms. Article selection and information extraction were performed using a double and independent approach. The Newcastle-Ottawa tool was used to assess the risk of bias in the included articles. The meta-analysis used the random-effects approach, with subgroup analysis and sensitivity analysis for risk of bias also being performed. Results: We included 101 articles with a total of 31,123 participants. The studies were conducted between 1990 and 2022, with Brazil accounting for the largest number of studies (n = 37). The overall seroprevalence of human toxocariasis was 31.0% (95% CI: 27.0-35.0%, I2 = 99%). The prevalence of the main characteristics observed in seropositive patients were as follows: ocular toxocariasis (30.0%), asymptomatic (26.0%), and presence of dogs at home (68.0%). In addition, the seroprevalence was lower in studies including only adults than in those including children or both. In contrast, no differences in seroprevalences were found between studies conducted in the community and hospital. Conclusion: The overall seroprevalence of human toxocariasis in Latin America and the Caribbean was high. Notably, our findings showed that the seroprevalence was increased among populations who kept a dog at home but was decreased in populations comprising only adults. Our findings can be used to establish epidemiological surveillance strategies for the prevention and early identification of toxocariasis.

Association of apolipoproteins and lipoprotein(a) with metabolic syndrome: a systematic review and meta-analysis.

BACKGROUND & AIMS: Apolipoproteins and lipoprotein(a) are associated with various cardiometabolic diseases, including insulin resistance, diabetes mellitus, hypertension, dyslipidemia, among others. This systematic review and meta-analysis was conducted to evaluate the association of these markers with metabolic syndrome (MetS). METHODS: We ran a systematic search through PubMed, Scopus, Embase, Ovid/Medline, and Web of Science on March 15, 2023. No language or date restrictions were applied. The only synthesised effect measure reported was the odds ratio (OR) with its corresponding 95% confidence interval (95% CI). We utilised the random-effects model for the quantitative synthesis. RESULTS: We analysed 50 studies (n = 150 519) with different definitions for MetS. Increased ApoB values were associated with MetS (OR = 2.8; 95% CI: 2.44-3.22; p < 0.01, I2 = 99%). Decreased ApoA1 values were associated with MetS (OR = 0.42; 95% CI: 0.38-0.47; p < 0.01, I2 = 99%). Increased values of the ApoB/ApoA1 ratio were associated with MetS (OR = 4.97; 95% CI: 3.83-6.44; p < 0.01, I2 = 97%). Decreased values of Lp(a) were associated with MetS (OR = 0.89; 95% CI: 0.82-0.96; p < 0.01; I2 = 92%). CONCLUSIONS: Increased values of ApoB and ApoB/ApoA1 ratio are associated with MetS, while decreased values of ApoA1 and Lp(a) are associated with MetS. These findings suggest that these lipid markers may serve as potential indicators for identifying subjects at risk of developing MetS. However, further research is required to elucidate the underlying mechanisms of these associations.

Evolutionary diversity of the endemic genera of the vascular flora of Chile and its implications for conservation.

As a direct consequence of global change, both natural and human-induced, a high percentage of biodiversity is now under threat worldwide. This has urged conservation planners to formulate and/or improve existing strategies to preserve species and their ecosystems. In this context, the present study focuses on two strategies using phylogeny-based measures of biodiversity to account for the processes that led to the biodiversity patterns observed today. It will contribute additional information that can aid decision-making regarding the assignment of threat status for some species, thus strengthening measures currently in use and facilitate the allocation of often scarce conservation resources. The Evolutionarily Distinct (ED) index prioritises species that are on long branches of the tree of life with few descendants, and the Evolutionarily Distinct and Globally Endangered (EDGE) index integrates evolutionary history with IUCN Red List threat status of species. It has been used mostly in animal groups, but since the threats faced by many plants have not been evaluated, it has been more difficult to compile for plants worldwide. Here, we apply the EDGE metric to species of the endemic genera of Chile. However, more than 50% of the endemic flora of the country are still lacking official threat status. We thus used an alternative measure (Relative Evolutionary Distinctness-RED), based on a range-weighted phylogenetic tree, which uses geographic ranges to adjust branch lengths, and calculate ED. The RED index was shown to be a suitable measure, yielding similar results compared to EDGE, at least for this group of species. Given the urgency to halt biodiversity loss and the time it would take to evaluate all species, we propose that this index is used to set conservation priorities until we can calculate EDGE for these unique endemic species. This would allow guiding decision-making until we can gather more data to assess and assign conservation status to new species.
