Role of arbuscular mycorrhizal fungi in lead translocation from Bidens pilosa L. plants to soil.

Bidens pilosa frequently forms a symbiotic association with arbuscular mycorrhizal fungi (AMF). This plant species can grow in Pb-polluted soils, accumulating Pb in its tissues. The aims of the study were to determine whether Pb accumulated in the tissues of B. pilosa can be transferred to the soil through AMF and to compare the role of AMF communities that have a history of exposure to the contaminant with those that have never been exposed. The experiment combined plants with and without Pb accumulated in their tissues, and inoculated with AMF collected from the rhizosphere of B. pilosa in soils contaminated and not contaminated with Pb. The results showed that AMF participate in the removal of Pb that had entered the plant and release it into the soil, as evidenced by the presence of Pb in the AMF spores and in the glomalin produced by AMF. We propose that Pb accumulation in AMF spores would be a protection mechanism that interrupts Pb uptake by the plant; however, that mechanism would not be fully exploited in detoxification, whereas the production of Pb-enriched glomalin could be an important detoxification mechanism to eliminate Pb already taken up by plants. AMF with a history of Pb exposure achieved only higher rates of root colonization, while AMF without previous exposure showed higher Pb concentration in the spores and higher glomalin production, and successfully removed Pb from both the roots and aboveground parts of the plant. The use of AMF communities not adapted to Pb may be a more effective option for microbe-mediated phytoremediation methods in which detoxification mechanisms are desirable.

[Consequence of hypertensive disorders during pregnancy (THE) on women's cardiovascular health]. / Consecuencia de los trastornos hipertensivos durante el embarazo (THE) sobre la salud cardiovascular de la mujer.

Patients with hypertensive disorders of pregnancy (HDP) are at increased risk of maternal-fetal complications and represent the third leading cause of maternal mortality. To date, it is known that women experiencing this condition during pregnancy have a higher future risk of cardiovascular events (CVD). Our objective was to report the incidence of new-onset hypertension in the postpartum period. We conducted a cohort study in high-risk pregnant patients who underwent ambulatory blood pressure monitoring (ABPM) between weeks 20-30. Patients were categorized as normotensive (NT) or gestational hypertensive (GH), excluding those with chronic hypertension, and were followed until the end of pregnancy with a postpartum assessment after 3months. Patients with HDP (39%) had a higher incidence of preeclampsia and newborns with low birth weight and preterm birth. A total of 177 pregnant women were analyzed for the primary outcome. Among those with GH, 33.3% vs 17.2% of NT (P=.014) reported new-onset hypertension. The odds ratio for developing new-onset hypertension was 2.3 (95%CI: 1.20-4.77), for those with GH. In conclusion, pregnant patients with GH assessed by ABPM between 20-30weeks are at higher risk of developing new-onset hypertension in the postpartum period, emphasizing the need for closer monitoring and control to prevent future cardiovascular complications.

[Prevalence, knowledge and control of arterial hypertension in vulnerable neighborhoods of Argentina: A Cross-sectional Study]. / Estudio de prevalencia, conocimiento y control de la hipertensión arterial en barrios vulnerables de Argentina.

INTRODUCTION: Hypertension (HTN) represents the primary individual risk factor, contributing significantly to the global burden of cardiovascular diseases (CVD). In our country, epidemiological research has highlighted substantial variations in the prevalence of these risk factors across different populations. However, there is a lack of epidemiological studies assessing exclusive cardiovascular risk factors within vulnerable neighborhoods characterized by extremely limited economic resources, sociocultural challenges, and inadequate healthcare access. METHODS: A multicenter cross-sectional observational study was conducted among individuals residing in economically deprived and marginalized communities, including informal settlements and underprivileged neighborhoods. Simple random sampling of households was employed. Blood pressure measurements, anthropometric assessments, and epidemiological, economic, and sociocultural questionnaires were administered. Results encompass prevalence rates, awareness levels, and blood pressure control across diverse regions. Logistic regression was utilized to identify independent variables influencing primary outcomes. RESULTS: A total of 989 participants were analyzed. The overall prevalence of hypertension was 48.2%. About 82% had a body mass index (BMI) >25. Approximately 45.3% had less than 6 years of formal education. Independent association was established between education levels below 6 years and higher hypertension prevalence. Among hypertensive individuals, 44% were unaware of their condition, with only 17.2% achieving control, correlated with having health insurance and a higher educational background. Merely 24% were receiving combined therapy. CONCLUSION: The prevalence of hypertension within vulnerable neighborhoods is alarmingly high, surpassing rates in other social strata. Knowledge, treatment, and control levels of hypertension are suboptimal, comparable to other populations. Inadequate use of combination therapy was observed. This study underscores the urgent need for targeted interventions addressing cardiovascular risk factors in poor areas to mitigate the burden of CVD.

Massive enlargement of gastric pouch as a complication of gastrojejunal anastomotic stenosis following one anastomosis laparoscopic gastric bypass: A case report.

INTRODUCTION AND IMPORTANCE: By 2030 it is predicted that 1 in 5 women and 1 in 7 men will be living with obesity. The only long-term effective strategy for achieving significant weight loss over time is surgical treatment. One Anastomosis Gastric Bypass (OAGB) has been proposed as an effective therapeutic option. Stenosis of Gastro-Jejunal Anastomosis (GJA) is one of the most common long-term complications and its cause recognized as multifactorial. CASE PRESENTATION: We present the case of a patient with a history of progressive postoperative oral intolerance after OAGB with 60 kg weight loss (BMI 20.7 kg/m2). Severe stenosis of the GJA and massive dilation of the gastric remnant was documented, treated multiple times with endoscopic balloon dilation. He was referred to our unit due to persistent symptoms. Revision surgery to a Gastric Bypass was programmed, ultimately performed via an open approach with resection of 80 % of the gastric remnant. CLINICAL DISCUSSION: Endoscopic dilatation and surgical revision are the two primary treatment options for GJA stricture. In refractory cases to pneumatic dilation, laparoscopic revision surgery is indicated, however an open approach is frequently required, as surgeries are technically demanding due to distorted anatomy in this population. CONCLUSION: Operations to correct chronic complications are tailored to the patient's anatomy as well as the symptoms or pathologies they are intended to correct. Whilst revision surgeries are associated with an increased risk of conversion, complications and longer hospital stay, they can be performed safely in experienced centers.

Evaluación de riesgos y mejora de la seguridad biológica y radiológica en la toma de radiografía torácica a pacientes con COVID-19.

INTRODUCTION: Health workers are at high risk of becoming infected with COVID-19. The objective of the study was to evaluate the risks and improve the biological and radiological safety measures for taking chest X-rays in patients with COVID-19 in a Social Security hospital in Utcubamba (Peru). MATERIAL AND METHODS: Quasi-experimental intervention study type before and after without a control group, carried out between May and September 2020. A process map and an analysis of failure modes and effects (FMEA) of radiological care were prepared. The gravity (G), occurrence (O), and detectability (D) values ??were found and the risk priority number (RPN) was calculated for each failure mode (FM). FM with RPN ≥ 100 and G ≥ 7 were prioritized. Improvement actions were implemented based on the recommendations of recognized institutions and the O and D values ??were re-evaluated. RESULTS: The process map consisted of 6 threads and 30 steps. 54 FM were identified, 37 of whom had RPN ≥ 100 and 48 had G ≥ 7. Most of the errors occurred during the examination 50% (27). After entering the recommendations, 23 FM had RPN ≥ 100. CONCLUSIONS: Although none of the measures applied through the FMEA made the failure mode impossible, they made it more detectable and less frequent and reduced the RPN for each failure mode; however, a periodic update of the process is necessary.

Prediabetes is more than a pre-disease: additional evidences supporting the importance of its early diagnosis and appropriate treatment.

AIM: To identify Prediabetes (PreD) as early and serious diabetes step using clinical-biochemical characteristics in the population of the Primary Prevention Diabetes Buenos Aires (PPDBA) study. METHODS: PPDBA Study evaluated benefits of adopting healthy lifestyles to prevent T2D. It recruited people 45-75 years of age with PreD (impaired fasting glycaemia [IFG], impaired glucose tolerance [IGT] or both, American Diabetes Association criteria), using an opportunistic approach. They completed a FINDRISC questionnaire, and those with a score ≥13 points were invited to participate. When they accepted, we performed an oral glucose tolerance test (OGTT) with a complete lipid profile and HbA1c while physicians completed a clinical history. We recruited 367 persons, and depending on OGTT results, the sample was divided into normals (NGT), PreD, or with diabetes (last one was excluded in our analysis). Data were statistically analyzed using parametric and nonparametric tests and logistic regression to identify parameters associated with PreD. RESULTS: From the recruited (n = 367) 47.7% have NGT, 48.5% PreD and 3.8% unknown T2D (excluded). People with PreD were significantly older, with a higher percentage of overweight/obesity, BMI, and larger waist circumference than NGT. They also showed significantly higher fasting and 2 h post glucose load, HbA1c, and triglyceride levels. No significant differences were recorded in the blood pressure, lipid profile though both groups had abnormally high LDL-c values. They also had a larger percentage of TG/HDL-c ratios (insulin resistance indicator) (55% vs. 37.5%). Logistic regression analysis showed that PreD was significant associated with age, waist circumference, and triglyceride above target values. CONCLUSION: Our findings showed that clinical and biochemical parameters were significantly different between people with PreD and those with NGT. This evidence supports the concept that PreD is a serious dysfunction, which should be early diagnosed and treated properly to prevent its transition to T2D and its complications.

Low aerobic capacity in McArdle disease: A role for mitochondrial network impairment?

BACKGROUND: McArdle disease is caused by myophosphorylase deficiency and results in complete inability for muscle glycogen breakdown. A hallmark of this condition is muscle oxidation impairment (e.g., low peak oxygen uptake (VO2peak)), a phenomenon traditionally attributed to reduced glycolytic flux and Krebs cycle anaplerosis. Here we hypothesized an additional role for muscle mitochondrial network alterations associated with massive intracellular glycogen accumulation. METHODS: We analyzed in depth mitochondrial characteristics-content, biogenesis, ultrastructure-and network integrity in skeletal-muscle from McArdle/control mice and two patients. We also determined VO2peak in patients (both sexes, N = 145) and healthy controls (N = 133). RESULTS: Besides corroborating very poor VO2peak values in patients and impairment in muscle glycolytic flux, we found that, in McArdle muscle: (a) damaged fibers are likely those with a higher mitochondrial and glycogen content, which show major disruption of the three main cytoskeleton components-actin microfilaments, microtubules and intermediate filaments-thereby contributing to mitochondrial network disruption in skeletal muscle fibers; (b) there was an altered subcellular localization of mitochondrial fission/fusion proteins and of the sarcoplasmic reticulum protein calsequestrin-with subsequent alteration in mitochondrial dynamics/function; impairment in mitochondrial content/biogenesis; and (c) several OXPHOS-related complex proteins/activities were also affected. CONCLUSIONS: In McArdle disease, severe muscle oxidative capacity impairment could also be explained by a disruption of the mitochondrial network, at least in those fibers with a higher capacity for glycogen accumulation. Our findings might pave the way for future research addressing the potential involvement of mitochondrial network alterations in the pathophysiology of other glycogenoses.

Hipertensión nocturna aislada en individuos con el virus de la inmunodeficiencia humana / Isolated nocturnal hypertension in individuals with human immunodeficiency virus

Introducción: La hipertensión nocturna aislada se asocia a mayor cantidad de eventos cardiovasculares y daño de órgano blanco por hipertensión arterial. La prevalencia en poblaciones especiales no se encuentra del todo descrita. El objetivo del siguiente estudio es describir la prevalencia de hipertensión nocturna aislada en población conviviendo con el virus de la inmunodeficiencia humana, y observar su relación con las categorías de presión arterial en el consultorio y los fenotipos de la medición ambulatoria de presión arterial de 24h. Metodología: Se realizó una cohorte retrospectiva en una población con el virus de la inmunodeficiencia humana en un hospital público de España, se registraron características clínico epidemiológicas, mediciones de presión arterial en consultorio y medición ambulatoria de presión arterial de 24h (MAPA). Se realizó un análisis en función de los diferentes fenotipos de presión arterial por MAPA, así como también en función de las diferentes categorías de presión arterial de consultorio se calcularon los riesgos para la hipertensión nocturna aislada. Resultados: Se incluyeron en el análisis 116 individuos, sin medicación antihipertensiva ni antecedentes de enfermedad cardiovascular establecida. Se describió una prevalencia de hipertensión nocturna del 23,3%. No se pudo demostrar diferencias significativas entre fenotipos por MAPA de ninguna variable propia del VIH. No hubo diferencias de riesgo ajustadas entre las diferentes categorías de normotensos en consultorio. Conclusiones: La hipertensión nocturna aislada es más frecuente en pacientes con VIH, y los valores de presión arterial de consultorio en normotensos no son suficientes para predecir HTA nocturna aislada.

Introduction: Isolated nocturnal hypertension is associated with a greater number of cardiovascular events and target organ damage due to arterial hypertension. It has been observed that patients in the general population with this entity do not have high blood pressure figures in the office; and it is necessary to perform an outpatient measurement to unmask it. The prevalence in special populations is not fully described. The objective of the following study is to describe the prevalence of isolated nocturnal hypertension in a population living with the human immunodeficiency virus and to observe its relationship with the categories of office blood pressure and the phenotypes of the 24-hour ambulatory blood pressure measurement. Methodology: A retrospective cohort was carried out in a population with human immunodeficiency virus in a public hospital in Spain, clinical epidemiological characteristics, office blood pressure measurements and 24-hour ambulatory blood pressure measurement (ABPM) were recorded. An analysis was performed based on the different ABPM blood pressure phenotypes, as well as based on the different office blood pressure categories, the risks for isolated nocturnal hypertension were calculated. Results: One hundred and sixteen individuals, without antihypertensive medication or history of established cardiovascular disease, were included in the analysis. A prevalence of nocturnal hypertension of 23.3% was described. It was not possible to demonstrate significant differences between phenotypes by ABPM of any variable specific to HIV. There were no adjusted risk differences between the different categories of office normotensives. Conclusions: Isolated nocturnal hypertension is more frequent in patients with HIV and office blood pressure values in normotensive patients are not sufficient to predict isolated nocturnal hypertension.

Effect of metabolic control on recurrent major adverse cardiovascular events and cardiovascular mortality in patients with premature coronary artery disease: Results of the Genetics of Atherosclerotic Disease study.

BACKGROUND AND AIMS: Coronary artery disease (CAD) is the leading cause of death around the world, and its rate of presentation is increasing at young ages. Despite the evidence that secondary prevention in CAD reduces the risk of recurrent major adverse cardiovascular events (MACE), no studies have analyzed the composite control of blood pressure, lipids, and glucose control in premature CAD. METHODS AND RESULTS: This was a real-world prospective cohort study of patients with premature CAD. The composite control in blood pressure <140/80 mmHg, LDL-C <70 mg/dL, non-HDL-C <100 mg/dL, and Hemoglobin A1c <8% was considered as metabolic control. The primary endpoint was the occurrence of non-fatal and fatal MACE. The data included 1042 patients with premature CAD. The mean age of the patients was 54.1 ± 8.1 years, 18.5% were women, and had a median follow-up of 59.1 ± 11.8 months. Of them, 7% had non-fatal MACE, and 4% had a fatal MACE. Overall, 21.3% achieved metabolic control, and 3.0% did not achieve any target. Cox regression analysis showed that percutaneous coronary intervention (Hazzard ratio = 1.883 [95% CI, 1.131-3.136]), C-reactive protein (1.046 [1.020-1.073]), blood pressure >140/90 mmHg (2.686 [1.506-4.791]), fibrates (2.032 [1.160-3.562]), calcium channel blockers (2.082 [1.158-3.744]) had greater risk to present a recurrent non-fatal MACE; whereas familial history of premature CAD (2.419 [1.240-4.721]), heart failure (2.139 [1.032-4.433]), LDL-C >70 mg/dL (4.594 [1.401-15.069]), and diuretics (3.328 [1.677-6.605]) were associated with cardiovascular mortality. CONCLUSIONS: The composite goal achievement in lipids, blood pressure and glucose, reduced the risk for recurrent MACE in 80%.

Plasma levels of efavirenz and frequency of the CYP2B6 516G>T polymorphism in people living with HIV-1 in Mexico.

Efavirenz (EFV) is a widely used antiretroviral, due to its safety, efficacy, and low cost. However, plasma concentrations have been related with an increased risk of virological failure and the appearance of serious adverse reactions. EFV is metabolized by Cytochrome P450, the main isoenzyme involved is CYP2B6 and the most relevant genetic polymorphisms found in several populations has been the CYP2B6 516G> T. The aim of this study was to identify the frequency of the CYP2B6 516G>T polymorphism and its effect on the plasma concentration of efavirenz (EFV) in a group of people living with HIV (PLWH) and undergoing EFV treatment in Morelos, Mexico. Ninety-six PLWH undergoing EFV treatment, at a daily dose of 600 mg orally in combination with other antiretrovirals (ARVs), were included in this study. The CYP2B6 516G>T polymorphism was detected using PCR-RFLP. The plasma concentrations of EFV were evaluated by high-resolution liquid chromatography coupled to a mass-mass detector, using a protein precipitation method. The median plasma EFV concentration was 4.6 µg/mL (IQR = 4.64) and 64.6% of the subjects had concentrations above the therapeutic range. The CYP2B6 516G>T genotype findings were as follows: 46.9% of the population presented the wild-type genotype (GG), while 45.8 % and 7.3 % showed the heterozygote (GT) and the polymorphic homozygote (TT) genotype, respectively. The homozygote G had the lowest plasma concentrations of EFV (median = 4.1 µg/mL and IQR = 1.7 µg/mL), followed by those with the GT genotype (median = 5.1 µg/mL and IQR = 3.0 µg/mL). Participants with the homozygous T genotype had the highest EFV concentrations (median = 9.7 µg/mL and IQR = 5.8 µg/mL). In conclusion, the CYP2B6 516G>T polymorphism was associated with plasma levels of EFV in PLWH undergoing ARV treatment. EFV plasma concentrations at 600mg doses were outside the therapeutic range in most subjects.

Reproductive outcomes of women with recurrent pregnancy losses and repeated implantation failures are significantly improved with immunomodulatory treatment.

This study investigated if immunomodulatory treatment improves the in-vitro fertilization (IVF) success rates of women with two or more recurrent pregnancy losses (RPL) and repeated implantation failures (RIF) with cellular immune abnormalities and thrombophilia. We performed a retrospective cohort study of 197 RPL patients who received immunomodulatory and anticoagulation treatment undergoing IVF cycles (fresh or frozen embryo transfer). Patients were divided into four groups; Group 1: women with RPL but without RIF, Group 2: women with RPL and RIF (≥3), Group 3: women with RPL after IVF cycles (>2) and without RIF, and Group 4: women with RPL after IVF cycles and RIF. Patients received immunomodulatory treatment with prednisone-only or prednisone and intravenous immunoglobulin G (IVIG) and anticoagulation treatment with low molecular weight heparin and low dose aspirin. IVF success rates of study groups were compared to those of the historical controls. The pregnancy rate of IVF cycles with immunomodulatory treatment was significantly increased in all patients (48.2 % vs. 33.0 %, P < 0.001), Group 1 (54.2 % vs. 30.5 %, P < 0.005) and Group 2 (33.3 % vs. 11.0 %, P < 0.005) as compared to historical controls. The live birth rates per ET cycle were significantly improved for all patients (1.8 % vs. 39.6 %, P < 0.001), and study groups compared to their historical controls (Group 1, 43.1 % vs. 0 %; Group 2, 33.3 % vs. 2.5 %; Group 3, 45.5 % vs. 2.3 %; and Group 4, 16.7 % vs. 1.2 %, P < 0.001, respectively). Immunomodulatory and anticoagulation treatment significantly improved the reproductive outcomes of IVF cycles in women with a history of RPL and/or RIF of immune etiologies.
