RESUMEN

OBJECTIVE: Simulation plays an important role in cardiopulmonary resuscitation training. Comparing postsimulation debriefing with rapid cycle deliberate practice could help determine the best simulation strategy for pediatric cardiopulmonary resuscitation training among pediatric residents. METHODS: This is a single-blind, prospective, randomized controlled study. First- and second year pediatric residents were enrolled and randomized into two groups (1:1 ratio): rapid cycle deliberate practice group (intervention) or postsimulation debriefing group (control). They participated in two rounds of simulated pediatric cardiopulmonary arrest to assess the simulated pediatric cardiopulmonary resuscitation performance gain (round 1) and retention after a 5-6 week washout period (round 2). Scenarios were video-recorded and analyzed by blinded evaluators. The main outcome was the time to initiation of chest compressions. Secondary outcomes included time to recognize a cardiopulmonary arrest, time to recognize a shockable rhythm, time to defibrillation, time to initiation of chest compressions after defibrillation, and chest compression fraction. RESULTS: Sixteen groups participated in the first round and fifteen groups in the second one. Time to intiation of chest compressions decreased from preintervention scenario to the round 1 testing scenario and increased from round 1 to round 2 testing scenario. However, no interaction effects nor group effects were observed (p=0.885 and p=0.329, respectively). There were no significant differences between the two groups regarding the secondary outcomes. CONCLUSION: Despite an overall improvement in simulated pediatric cardiopulmonary resuscitation performance, we did not observe significant differences between the two groups regarding the analyzed variables. The decline in simulated pediatric cardiopulmonary resuscitation performance after 5 weeks suggests the need for shorter time intervals between training sessions.

RESUMEN

Background: There is a lack of specific studies on the management of infections in patients receiving palliative care (PC) in the final stages of life and during the active process of death, related to specific nursing care. There is clinical and social importance as patients in PC represent a vulnerable population, and adequate management of infections is crucial to improve quality of life and the experience of comfort. Objective: This study analyzed how infections are managed in patients undergoing PC at the end-of-life and in the active process of death in two hospital health services. Design: This is an observational, analytical, and retrospective study. Settings: Data collection took place in two hospitals that assist individuals who are hospitalized under PC, located in Brazil, in a city in the interior of the state of São Paulo. Measurements and Results: The sample consisted of 113 medical records, in which the oncological diagnosis was the most prevalent. There was a predominance of infection diagnoses based on the patient's clinical symptoms, the main focus being the pulmonary, in individuals at the end-of-life. The management of infection in the study sample occurred through care and procedures that generate physical discomfort, however aiming at relieving symptoms. Such findings must be documented, as they invite us to reflect on our practical attitudes and what it means to be comfortable for these people, making it possible to incorporate this information into the design of interventions focused on enhancing the experience of comfort.

RESUMEN

Salivary glands' neoplasms are hard to diagnose and present a complex etiology. However, several viruses have been detected in these neoplasms, such as HCMV, which can play a role in certain cancers through oncomodulation. The co-infections between HCMV with betaherpesviruses (HHV-6 and HHV-7) and polyomaviruses (JCV and BKV) has been investigated. The aim of the current study is to describe the frequency of HCMV and co-infections in patients presenting neoplastic and non-neoplastic lesions, including in the salivary gland. Multiplex quantitative polymerase chain reaction was used for betaherpesvirus and polyomavirus quantification purposes after DNA extraction. In total, 50.7% of the 67 analyzed samples were mucocele, 40.3% were adenoma pleomorphic, and 8.9% were mucoepidermoid carcinoma. Overall, 20.9% of samples presented triple-infections with HCMV/HHV-6/HHV-7, whereas 9.0% were co-infections with HCMV/HHV-6 and HCMV/HHV-7. The largest number of co-infections was detected in pleomorphic adenoma cases. All samples tested negative for polyomaviruses, such as BKV and JCV. It was possible to conclude that HCMV can be abundant in salivary gland lesions. A high viral load can be useful to help better understand the etiological role played by viruses in these lesions. A lack of JCV and BKV in the samples analyzed herein does not rule out the involvement of these viruses in one or more salivary gland lesion subtypes.

RESUMEN

Type 1 Diabetes Mellitus (T1DM) can generate severe complications, such as Diabetic Kidney Disease (DKD) or Diabetic Nephropathy (DN), with it emerging as the leading cause of terminal (end-stage) renal disease all over the world. For T1DM, the clinical evaluation of DKD uses markers like the Glomerular Filtration Rate (GFR) and the Urinary Albumin Excretion (UAE). However, early diagnosis of DKD is still a challenge. For this reason, investigating molecular markers, such as microRNAs (miRNAs), offers a promising perspective to an early diagnosis, highlighting the stability and the ability to reflect incipient molecular manifestations. Thus, here we investigated four miRNAs (hsa-let-7i-5p, hsa-miR-143-3p, hsa-miR-501-3p, and hsa-miR-100-5p) regarding nephropathy in patients with T1DM, considering the albuminuria (micro and macro) as a standard to evaluate the groups. As a result, we found a reduced expression of miR-100-5p in patients with MIC, indicating a protective role in nephropathy. Beyond that, expression levels between the groups (Non vs. UAE) were not significant when comparing the miRNAs miR-501-3p and miR-143-3p. Finally, miR-143-3p and miR-100-5p were linked to some target genes such as AKT1, MMP13, and IGF1R, that are connected to signal pathways and cellular metabolism.

RESUMEN

BACKGROUND: COVID-19, caused by SARS-CoV-2, was responsible for higher morbidity and mortality in renal transplant recipients (RTx). The objective of the study was to evaluate the impact of COVID-19 infection on RTx in a single center in Brazil. METHODS: A cohort of 135 RTx was evaluated between December 2019 and June 202l, and demographics, clinical, and laboratory profiles were analyzed from deceased donors with COVID-19. RESULTS: Diabetic and RTx from extended criterion donors presented more frequently the severe form of the disease. Serum creatinine (sCr) after 3 months of diagnosis of COVID-19 varied according to the severity of infection. The lethality rate was higher in the group with severe symptoms (65%) compared with those with mild infection (1.5%). CONCLUSION: The increase in sCr was associated with disease severity. The lethality rate for COVID-19 was 26.6%. These rates are 10-20 times higher than those reported in the general population and suggest that rigorous observation, early diagnosis, and disease prevention measures are crucial in RTx.

RESUMEN

We evaluated the association of cardiovascular autonomic neuropathy (CAN), blood pressure (BP) and Vitamin D (VD) levels before and after high-dose cholecalciferol supplementation (4000/10,000) UI/day) for 12 weeks in patients (N = 67) with type 1 diabetes mellitus (T1DM). Based on this prospective controlled pilot study, patients were divided into group 1 (N = 23 with CAN) and group 2 (N = 44 without CAN). At baseline, group 1 had higher systolic BP (SBP) during sleep (115 ± 14 vs. 107 ± 12 mmHg, p = 0.04) and lower nocturnal dipping (3 ± 5 vs. 8 ± 6%, p = 0.009). Among those with loss of nocturnal dipping, 45.4% (20/44) had CAN, while in normal nocturnal dipping group it occurred only in 13% (3/23) (p = 0.007). Non-dipper group had worse CAN parameters when compared to dipper group [Very low frequency (VLF) (2.5 ± 0.5vs.2.8 ± 0.4 s, p = 0.01), total power (TP) (2.9 ± 0.6 vs. 3.3 ± 0.4 s, p = 0.01), Valsalva coefficient (1.5 ± 0.4 vs. 1.8 ± 0.6, p = 0.06)]. After VD, only group 1 improved CAN parameters [TP (2.5 ± 0.4 vs. 2.8 ± 0.6, p = 0.01) and VLF (2.2 ± 0.4 vs. 2.4 ± 0.5, p = 0.03). Group 1 presented a reduction in morning SBP (120 ± 20 vs. 114 ± 17 mmHg, p = 0.038) and in morning SBP surge (13 ± 13 vs. 5 ± 14, p = 0.04). High-dose VD was associated with improved CAN parameters and reduced awake SBP and morning SBP surge. These findings suggest that VD may benefit patients with cardiovascular autonomic neuropathy.

RESUMEN

Ticks are obligate hematophagous parasites that can transmit to vertebrate hosts several pathogens, including viruses, bacteria, protozoa and helminths. Among these agents, some Borrelia species some Borrelia species cause disease in humans and other vertebrate hosts; therefore, they have medical and veterinary health importance. To gather additional information on Borrelia species in Brazil, the current study aimed to detect the presence of these species in Ornithodoros cavernicolous ticks collected in September 2019 from cement pipes that are used by bats as shelter in a farm located in the midwestern region of Brazil. DNA samples obtained from 18 specimens of O. cavernicolous were subjected of two polymerase chain reactions, targeting a segment of the Borrelia fla B gene. Of the samples tested, only one (6 %, 1/18) showed amplification. The nucleotide sequence of the amplified DNA showed more than 97 % (293/300) identity with a sequence of a Borrelia sp. detected in blood collected from a bat from Macaregua Cave, Colombia, and more than 97 % (292/300) detected in lungs from vampire bats from northeastern Brazil. The deduced amino acid sequences were identical to each other. Phylogenetic analysis indicated that these sequences formed a group of Borrelia species (putatively associated with bats) that is closely related to sequences of Borrelia species of the Lyme borreliosis group. Further investigations should be carried out in order to determine whether the sequence of the Borrelia sp. we found belongs to a new taxon. It will also be of great importance to determine which vertebrate hosts, besides bats, O. cavernicolous ticks can parasitize in order to investigate whether the Borrelia sp. we found may be transmitted and cause disease to the other vertebrate hosts.

RESUMEN

Aging is characterized by significant physiological changes, with the degree of decline varying significantly among individuals. The preservation of intrinsic capacity over the course of an individual's lifespan is fundamental for healthy aging. Locomotion, which entails the capacity for independent movement, is intricately connected with various dimensions of human life, including cognition, vitality, sensory perception, and psychological well-being. Notably, skeletal muscle functions as a pivotal nexus within this intricate framework. Any perturbation in its functionality can manifest as compromised physical performance and an elevated susceptibility to frailty. Magnesium is an essential mineral that plays a central role in approximately 800 biochemical reactions within the human body. Its distinctive physical and chemical attributes render it an indispensable stabilizing factor in the orchestration of diverse cellular reactions and organelle functions, thereby rendering it irreplaceable in processes directly impacting muscle health. This narrative review offers a comprehensive exploration of the pivotal role played by magnesium in maintaining skeletal muscle integrity, emphasizing the critical importance of maintaining optimal magnesium levels for promoting healthy aging.

RESUMEN

PURPOSE: The aim of this study was to evaluate whether sleep deprivation can induce degenerative changes in rat sublingual glands. METHODS: For this purpose, a total of 24 males were distributed into three groups: control (n = 8), in which the animals were not subjected to any procedure; sleep deprivation (n = 8) in which the animals were submitted to sleep deprivation for 96 h; recovery (n = 8), in which the animals were subjected to paradoxical sleep deprivation for 96 consecutive hours followed by 96 h without intervention. Morphological changes in sublingual glands as well as the immunoexpressions of some proteins, such as Ki-67, p16, cleaved caspase-3 and BCL-2 were investigated in this setting. RESULTS: The results showed that paradoxical sleep deprivation induced tissue degeneration as a result of the presence of pyknosis, vacuoles and areas of salivary retention, in the experimental groups. Expression of cleaved caspase 3 and BCL-2 were increased in both sleep deprivation and recovery groups. The analysis of Ki-67 showed an increase in expression only in the recovery group, associated with a decrease in p16 levels. CONCLUSION: Sleep deprivation can induce a degenerative process in the parenchyma of sublingual gland by means of dysregulation of apoptosis associated with proliferative activity.

RESUMEN

Bisphosphonates are a class of drugs that induce bone cancer cell death and favor bone regeneration, making them suitable for bone cancer treatment. However, when combined with bioactive glasses to enhance bone regeneration, a chemical bond between biphosphonates and the glass surface inactivates their mechanism of action. A new colloidal hydrogel-based drug delivery system could overcome that limitation once bisphosphonates, such as zoledronic acid (ZA), are incorporated into hydrogel micelles, avoiding their interaction with the glass surface. In this work, we proposed formulations based on a poloxamer 407 thermo-responsive hydrogel matrix containing holmium-doped bioactive glass nanoparticles and different concentrations (0.05 and 5 mg/mL) of ZA. We characterized the influence of the glass and the ZA on the hydrogel properties. In addition, a drug concentration screening was performed, and biological characterizations evaluated the best result. The biological characterization consisted of evaluating cytotoxicity and in vitro bone regeneration ability through cell migration and quantification of genes related to osteogeneses through RT-PCR. The results suggest that the addition of glasses and ZA to the poloxamer did not significantly influence the sol-gel transition of the hydrogels (around 13 °C) regardless of the ZA content. However, the ZA at high concentration (PL-ZA100) decreased the enthalpy of gel formation from 68 to 43 kJ.mol-1 when compared with the pure hydrogel formulation (PL), suggesting a water structurer role of ZA, which is withdrawn when glass particles are added to the system (PL-BG5Ho-ZA100). Solid-state 31P nuclear resonance spectroscopy results showed that part of the ZA is chemically bonded to the glass surface, which explains the withdrawal in the water structurer role of ZA when the glasses were incorporated into the hydrogel. Besides, based on the drug release results, we proposed a model where part of the ZA is "free," encapsulated in the hydrogel matrix, while another part of the ZA is bonded to the glass surface. Finally, considering the in vitro results and our proposed model, the ratio between "free" and "bonded" ZA in our drug delivery systems showed in vitro evidence of a cancer treatment that selectively kills osteosarcoma cells while still favoring an osteogenic microenvironment. By overcoming the limitation of combining bisphosphonates with bioactive glasses, hydrogel-based drug delivery systems can be a solution for the development of new formulations proposed for bone cancer treatment in conjunction with bone regeneration.

RESUMEN

BACKGROUND: This study aimed to examine factors associated with postpartum depression (PPD) symptoms during the COVID-19 pandemic among postpartum women in five countries, a subject that has not been investigated thus far. METHODS: A multi-country, cross-sectional, online survey was conducted with a convenience sample of 3,523 postpartum women in Brazil, South Korea, Taiwan, Thailand, and the United Kingdom, from July to November 2021. Sociodemographic and obstetric data, food insecurity, COVID-19 positive status, COVID-19 vaccination, infant feeding, breastfeeding belief score, and social support were investigated. PPD and social support were measured using the Edinburgh Postnatal Depression Scale and Maternal Social Support Scale, respectively. Descriptive statistics, chi-squared tests, and t-tests were used to identify associations with PPD symptoms. A binary logistic regression model was used to identify explanatory factors associated with PPD and adjusted odds ratios (OR) and 95% confidence intervals (CIs) were calculated. RESULTS: Women in Taiwan (AOR = 0.5; 95%CI 0.34, 0.73) and Thailand (AOR = 0.68; 95%CI 0.46, 0.99) had a lower risk of PPD symptoms than those in Brazil. In addition, women with planned pregnancies had a lower risk of PPD (AOR = 0.74; 95%CI 0.60, 0.91). Younger women (AOR = 1.62; 95%CI 1.05, 2.51), health problems during pregnancy, delivery, or postpartum (AOR = 1.71; 95%CI 1.42, 2.06), and no change or worse food insecurity during COVID-19 (AOR = 1.66; 95%CI 1.21, 1.27 for no change and AOR = 1.68; 95%CI 1.27, 1.23, respectively) presented a higher likelihood of having PPD. Feeding babies with expressed human milk (AOR = 1.25; 95%CI 1.03, 1.50) and/or complementary food (AOR = 1.51; 95%CI 1.17, 1.94) were associated with PPD symptoms. Women who received low (AOR = 7.74; 95%CI 5.43, 11.03) or medium support (AOR = 3.25; 95%CI 2.71, 3.88) had higher likelihoods of PPD. CONCLUSION: PPD symptoms during the pandemic were high in young women, particularly Brazilian women, with health problems in the puerperal pregnancy cycle who fed their babies expressed breast milk and/or complementary food. Low social support also impacted PPD symptoms. This study highlights the need for the professional screening for PPD and provision of virtual or personal support.

RESUMEN

OBJECTIVES: To assess the prevalence of burnout, anxiety and depression symptoms, and posttraumatic stress disorder (PTSD) in PICU workers in Brazil during the first peak of the COVID-19 pandemic. To compare the results of subgroups stratified by age, gender, professional category, health system, and previous mental health disorders. DESIGN: Multicenter, cross-sectional study using an electronic survey. SETTING: Twenty-nine public and private Brazilian PICUs. SUBJECTS: Multidisciplinary PICU workers. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Self-reported questionnaires were used to measure burnout (Maslach Burnout Inventory), anxiety and depression (Hospital Anxiety and Depression Scale), and PTSD (Posttraumatic Stress Disorder Checklist for Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition [PCL-5]) in 1,084 respondents. Subjects were mainly young (37.1 ± 8.4 yr old) and females (85%), with a median workload of 50 hours per week. The prevalence of anxiety and depression was 33% and 19%, respectively, whereas PTSD was 13%. The overall median burnout scores were high in the emotional exhaustion and personal accomplishment dimensions (16 [interquartile range (IQR), 8-24] and 40 [IQR, 33-44], respectively) whereas low in the depersonalization one (2 [IQR, 0-5]), suggesting a profile of overextended professionals, with a burnout prevalence of 24%. Professionals reporting prior mental health disorders had higher prevalence of burnout (30% vs 22%; p = 0.02), anxiety (51% vs 29%; p < 0.001), and depression symptoms (32.5% vs 15%; p < 0.001), with superior PCL-5 scores for PTSD ( p < 0.001). Public hospital workers presented more burnout (29% vs 18.6%, p < 0.001) and more PTSD levels (14.8% vs 10%, p = 0.03). Younger professionals were also more burned out ( p < 0.05 in all three dimensions). CONCLUSIONS: The prevalence of mental health disorders in Brazilian PICU workers during the first 2020 peak of COVID-19 was as high as those described in adult ICU workers. Some subgroups, particularly those reporting previous mental disorders and younger professionals, should receive special attention to prevent future crises.

RESUMEN

The treatment of bone cancer involves tumor resection followed by bone reconstruction of the defect caused by the tumor using biomaterials. Additionally, post-surgery protocols cover chemotherapy, radiotherapy, or drug administration, which are employed as adjuvant treatments to prevent tumor recurrence. In this work, we reviewed new strategies for bone cancer treatment based on bioactive glasses as carriers of cancer-targeted and other drugs that are intended for bone regeneration in conjunction with adjuvant treatments. Drugs used in combination with bioactive glasses can be classified into cancer-target, osteoclast-target, and new therapies (such as gene delivery and bioinorganic). Microparticulated, nanoparticulated, or mesoporous bioactive glasses have been used as drug-delivery systems. Additionally, surface modification through functionalization or the production of composites based on polymers and hydrogels has been employed to improve drug-release kinetics. Overall, although different drugs and drug delivery systems have been developed, there is still room for new studies involving kinase inhibitors or antibody-conjugated drugs, as these drugs have been poorly explored in combination with bioactive glasses.

RESUMEN

Background: Considering the potential role of miRNAs as biomarkers and their interaction with both nuclear and mitochondrial genes, we investigated the miRNA expression profile in type 1 diabetes (T1DM) patients, including the pathways in which they are involved considering both nuclear and mitochondrial functions. Methods: We analyzed samples of T1DM patients and control individuals (normal glucose tolerance) by high throughput miRNA sequencing (miRNome). Next, five miRNAs - hsa-miR-26b-5p, hsa-let-7i-5p, hsa-miR-143-3p, hsa-miR-501-3p and hsa-miR-100-5p - were validated by RT-qPCR. The identification of target genes was extracted from miRTarBase and mitoXplorer database. We also performed receiver operating characteristic (ROC) curves and miRNAs that had an AUC > 0.85 were considered potential biomarkers. Results: Overall, 41 miRNAs were differentially expressed in T1DM patients compared to control. Hsa-miR-21-5p had the highest number of predicted target genes and was associated with several pathways, including insulin signaling and apoptosis. 34.1% (14/41) of the differentially expressed miRNAs also targeted mitochondrial genes, and 80.5% (33/41) of them targeted nuclear genes involved in the mitochondrial metabolism. All five validated miRNAs were upregulated in T1DM. Among them, hsa-miR-26b-5p showed AUC>0.85, being suggested as potential biomarker to T1DM. Conclusion: Our results demonstrated 41 DE miRNAs that had a great accuracy in discriminating T1DM and control group. Furthermore, we demonstrate the influence of these miRNAs on numerous metabolic pathways, including mitochondrial metabolism. Hsa-miR-26b-5p and hsa-miR-21-5p were highlighted in our results, possibly acting on nuclear and mitochondrial dysfunction and, subsequently, T1DM dysregulation.

RESUMEN

Resumo O objetivo deste artigo é analisar as evidências disponíveis na literatura sobre o processo de identificação de pessoas adultas e idosas que podem se beneficiar dos cuidados paliativos na atenção primária à saúde. Trata-se de revisão integrativa da literatura realizada nas bases de dados PubMed, CINAHL, LILACS, Web of Science e Embase. Foram selecionados oito estudos, nos quais foram distinguidos diferentes instrumentos com o propósito de identificar as pessoas que podem se beneficiar dos cuidados paliativos no contexto da atenção primária à saúde. A incorporação desses instrumentos na prática clínica é urgente, para aumentar o alcance e a efetividade dos serviços oferecidos pelos profissionais de saúde, considerando o perfil demográfico e epidemiológico atual que aponta para o aumento de pessoas com potencial necessidade de cuidados paliativos. Diferentes instrumentos têm sido utilizados com sucesso na identificação do cuidado paliativo no contexto da atenção primária à saúde. No entanto, alguns possuem fragilidades, como o fato de permitirem a identificação apenas das pessoas com doenças oncológicas, deixando de fora as demais condições de saúde, o que reforça a necessidade de mais estudos sobre esta temática.


Abstract This article aims to analyze the evidence available in the literature on the process of identifying adults and elderly people who can benefit from palliative care (PC) in primary health care (PHC). This is an integrative literature review carried out in PubMed, CINAHL, LILACS, Web of Science, and Embase. Eight studies were selected, in which different instruments and methods were distinguished with the purpose of identifying people who can benefit from PC in the context of PHC. The incorporation of these instruments into clinical practice is urgent in order to increase the reach and effectiveness of the services offered by health professionals, considering the current demographic and epidemiological profile that points to the increase of people with a potential need for PC. Different instruments have been successfully used to identify PC in the context of PHC. However, some have weaknesses, such as the fact that they only allow the identification of people with oncological diseases, leaving out other health conditions, which reinforces the need for further studies on this topic.

RESUMEN

OBJECTIVE: to identify the occurrences related to peripheral venipuncture and hypodermoclysis among patients hospitalized in a general hospital and in an exclusive hospital institution for the care of patients in palliative cancer care. METHOD: an observational, descriptive and multicenter study. The consecutive and non-probabilistic sample consisted of 160 cancer patients hospitalized in Palliative Care. The outcome variable corresponded to the occurrences and complications related to each type of puncture. A questionnaire containing the sociodemographic and clinical variables and a structured script for monitoring and daily evaluation of the puncture were used. Descriptive statistics were employed for data analysis. RESULTS: the occurrences related to venipuncture at a general hospital were blood soiling at catheter insertion (17.4%) and expired use period (15.8%), while at a specific service for the care of patients under palliative care they were expired use period (32%) followed by infiltration (18.9%). As for hypodermoclysis, there were two subcutaneous punctures with phlogistic signs (1.0%) at the general hospital and a hematoma at the catheter insertion site (0.5%). At the specific service for the care of patients under palliative care there were three subcutaneous punctures with phlogistic signs (5.7%). CONCLUSION: the number of occurrences related to peripheral venipuncture was higher than those related to hypodermoclysis.

RESUMEN

BACKGROUND: Little is known about the evolution of peripheral arterial disease (PAD) since diagnosis and its association with glycemic and lipid control in patients with Type 2 Diabetes Mellitus (T2DM). OBJECTIVE: Evaluate the actual criteria to start screening PAD with ankle-brachial index (ABI) in T2DM patients and assess its progression and relationship with glycemic and lipid control since diagnosis. METHODS: We performed a 3-year prospective cohort study with two groups: group 1 (978 individuals with T2DM undergoing drug treatment) and group 2 [221 newly diagnosed drug-naive (< 3 months) patients with T2DM]. PAD diagnosis was by ABI ≤ 0.90, regardless any symptoms. RESULTS: As expected, abnormal ABI prevalence was higher in group 1 vs. Group 2 (87% vs. 60%, p < 0.001). However, abnormal ABI prevalence did not differ between patients over and under 50 years in both groups. Our drug-naive group stabilizes ABI (0.9 ± 0.1 vs 0.9 ± 0.1, p = NS) and improved glycemic and lipid control during follow-up [glycated hemoglobin (HbA1c) = 8.9 ± 2.1 vs 8.4 ± 2.3%, p < 0.05; LDL = 132 ± 45 vs 113 ± 38 mg/dL, p < 0.01, respectively]. When compared, patients who evolved with normalization or maintained normal ABI levels at the end [Group A, N = 60 (42%)] with those who decreased ABI to abnormal levels (ABI basal 1.0 ± 0.1 vs final 0.85 ± 0.1, p < 0.001) [Group B, N = 26 (18%)], an improvement in HbA1c (9 ± 2 vs 8 ± 2%, p < 0.05) and a correlation between the final HbA1c with ABI (r = - 0.3, p = 0.01) was found only in the first. In addition, a correlation was found between albuminuria variation and ABI solely in group A (r = - 0.3; p < 0.05). CONCLUSION: Our study suggests that ABI should be measured at diagnosis in T2DM patients, indicating that current criteria to select patients to screen PAD with ABI must be simplified. An improvement in albuminuria and glycemic and lipid control could be related with ABI normalization in newly diagnosed T2DM drug-naive patients.
