RESUMO

BACKGROUND: Patients with haemophilic arthropathy suffer chronic pain that affects and restricts their quality of life. Visualization of movement through immersive virtual reality is used for pain management. AIM: To evaluate the efficacy of 180-degree immersive VR motion visualization therapy in patients with haemophilic ankle arthropathy. METHODS: Prospective, multicentre pilot study. Fifteen adult patients with bilateral haemophilic ankle arthropathy were recruited (mean age: 42.73 ± 12.36 years). The intervention lasted 4 weeks, with daily home sessions of 180-degree immersive motion visualization. The patients were given virtual reality glasses to use with their smartphones. From the YouTube mobile app® they accessed the recorded video with access from the He-Mirror App®. The study variables were joint state (Haemophilia Joint Health Score), pressure pain threshold (pressure algometer), muscle strength (dynamometry) and range of motion (goniometry). Three evaluations were performed: at baseline (T0), after the intervention (T1) and at the end of a 16-week follow-up period (T2). RESULTS: No patient developed ankle hemarthrosis during the experimental phase. In the repeated measures analysis we found statistically significant differences in joint state (F = 51.38; η2 p = .63), pressure pain threshold of the lateral malleolus (F = 12.34; η2 p = .29) and range of motion (F = 11.7; η2 p = .28). CONCLUSIONS: Therapy using immersive motion visualization does not cause hemarthrosis. This intervention can improve joint condition, pressure pain threshold and range of motion in patients with ankle arthropathy. Changes greater than the MDC were reported in more than 40% of patients for the variables pressure pain threshold, anterior tibialis strength and range of motion, which were considered clinically relevant.

RESUMO

This study examines the injuries suffered by players (n=166) of the Spanish national men's under-18 and under-20 rugby teams between 2015 and 2017, and identifies the actions involved in their occurrence. All injuries (total n=78) sustained during matches and training were recorded as recommended by World Rugby, and injury incidence rates per 1000 player-hours (ph) calculated for both types of activity. Injuries occurred more commonly during matches than during training (incidence 105.3 [95% CI: 78.7-131.9] per 1000 [ph] of match play, vs 1.16 [95% CI: 0.69-1.62] per 1000 ph of training), and most days absent per 1000 ph during matches with<3 days rest since the previous match (4209.2 [95% CI: 3516.2-4902.1] per 1000 ph of match play, vs 1947.4 [95% CI: 1511.8-2382.9] per 1000 ph of match play in matches with>3 days rest). These results provide information that may be useful in the development of strategies aimed at reducing the incidence of injuries.

RESUMO

Stomata allow CO2 uptake by leaves for photosynthetic assimilation at the cost of water vapor loss to the atmosphere. The opening and closing of stomata in response to fluctuations in light intensity regulate CO2 and water fluxes and are essential for maintaining water-use efficiency (WUE). However, a little is known about the genetic basis for natural variation in stomatal movement, especially in C4 crops. This is partly because the stomatal response to a change in light intensity is difficult to measure at the scale required for association studies. Here, we used high-throughput thermal imaging to bypass the phenotyping bottleneck and assess 10 traits describing stomatal conductance (gs) before, during and after a stepwise decrease in light intensity for a diversity panel of 659 sorghum (Sorghum bicolor) accessions. Results from thermal imaging significantly correlated with photosynthetic gas exchange measurements. gs traits varied substantially across the population and were moderately heritable (h2 up to 0.72). An integrated genome-wide and transcriptome-wide association study identified candidate genes putatively driving variation in stomatal conductance traits. Of the 239 unique candidate genes identified with the greatest confidence, 77 were putative orthologs of Arabidopsis (Arabidopsis thaliana) genes related to functions implicated in WUE, including stomatal opening/closing (24 genes), stomatal/epidermal cell development (35 genes), leaf/vasculature development (12 genes), or chlorophyll metabolism/photosynthesis (8 genes). These findings demonstrate an approach to finding genotype-to-phenotype relationships for a challenging trait as well as candidate genes for further investigation of the genetic basis of WUE in a model C4 grass for bioenergy, food, and forage production.

RESUMO

Sorghum (Sorghum bicolor) is a model C4 crop made experimentally tractable by extensive genomic and genetic resources. Biomass sorghum is studied as a feedstock for biofuel and forage. Mechanistic modeling suggests that reducing stomatal conductance (gs) could improve sorghum intrinsic water use efficiency (iWUE) and biomass production. Phenotyping to discover genotype-to-phenotype associations remains a bottleneck in understanding the mechanistic basis for natural variation in gs and iWUE. This study addressed multiple methodological limitations. Optical tomography and a machine learning tool were combined to measure stomatal density (SD). This was combined with rapid measurements of leaf photosynthetic gas exchange and specific leaf area (SLA). These traits were the subject of genome-wide association study and transcriptome-wide association study across 869 field-grown biomass sorghum accessions. The ratio of intracellular to ambient CO2 was genetically correlated with SD, SLA, gs, and biomass production. Plasticity in SD and SLA was interrelated with each other and with productivity across wet and dry growing seasons. Moderate-to-high heritability of traits studied across the large mapping population validated associations between DNA sequence variation or RNA transcript abundance and trait variation. A total of 394 unique genes underpinning variation in WUE-related traits are described with higher confidence because they were identified in multiple independent tests. This list was enriched in genes whose Arabidopsis (Arabidopsis thaliana) putative orthologs have functions related to stomatal or leaf development and leaf gas exchange, as well as genes with nonsynonymous/missense variants. These advances in methodology and knowledge will facilitate improving C4 crop WUE.

RESUMO

BACKGROUND: Prophylactic treatment is the gold standard in the treatment of patients with haemophilia. Prophylaxis with extended half-life (EHL) treatment has shown long-term safety and efficacy in patients with haemophilia. AIM: To evaluate the efficacy of prophylaxis with EHL treatment in the frequency of haemarthrosis and musculoskeletal health in adult patients with severe haemophilia A. METHODS: Prospective cohort study. Forty-six patients with severe haemophilia A were recruited. The frequency of haemarthrosis (self-reports), joint condition (Haemophilia Joint Health Score), pain intensity (visual analogue scale), range of motion (goniometry), and strength (dynamometry) and muscle activation (surface electromyography) were evaluated. Three assessments were carried out: at baseline (T0), at 6 months (T1) and at 12 months following treatment (T2). RESULTS: There were significant changes in the within-subject effect in the frequency of haemarthrosis in elbow (F(1.05;96.20) = 3.95; P < .001) and knee (F(1.73;157.99) = 9.96; P < .001). Significant within-subject effect in elbow pain intensity (F(2;182) = 63.51; P < .001) was found. The mean values of the frequency haemarthrosis in elbow (from .66±1.01 to .04±.20) and knees (from .55±.68 to .33±.53) decrease after the period study. The intensity of elbow pain and (from 3.08±1.69 to 2.67±1.73), decrease after the 12-month follow-up period. CONCLUSIONS: Prophylaxis with extended half-life treatment reduces the frequency of haemarthrosis in elbow and knee in adult patients with haemophilia. EHL treatment reduces the intensity of elbow pain in patients with haemophilic arthropathy.

RESUMO

BACKGROUND: Pain is a major characteristic in haemophilic arthropathy. Identifying the psychosocial variables affected by pain can help when addressing these patients. AIM: To assess the relationship between perceived intensity of chronic pain and joint damage, kinesiophobia, catastrophism, anxiety and perceived quality of life in adult patients with haemophilic arthropathy. METHODS: Multicentre cross-sectional descriptive study. Seventy-seven adult patients with haemophilic arthropathy were recruited. The usual and maximum pain intensity (Visual Analog Scale), joint status (Haemophilia Joint Health Score), Kinesiophobia (Tampa Scale of Kinesiophobia), catastrophism (Pain catastrophizing scale), anxiety (State-Trait Anxiety inventory) and perceived quality of life (36-Item Short Form Health Survey) were evaluated. The correlation between usual and maximum pain intensity with quantitative variables was obtained with Spearman`s correlation test. Kruskal-Wallis one-way ANOVA analysed differences in perceived pain according to the severity and type of treatment, and development of inhibitors. RESULTS: The usual intensity of perceived pain correlated positively with catastrophism, kinesiophobia, and state and trait anxiety. The same results were obtained when analysing the maximum perception of pain. We found an inverse correlation between the physical component of perceived quality of life and usual and maximum pain intensity perceived by patients. CONCLUSION: Psychosocial factors affect the painful experience of patients with haemophilic arthropathy. Pain intensity affects the quality of life of these patients.

RESUMO

BACKGROUND: Haemophilic knee arthropathy presents functional and structural alterations and chronic pain. Self-induced myofascial release aims to treat fascial restrictions and improve functionality. AIM: This study investigated the safety and effectiveness of a self-induced myofascial release protocol in patients with haemophilic knee arthropathy. METHODS: Twenty-five patients with bilateral haemophilic knee arthropathy were recruited (n = 50 knees). The patients followed an intervention protocol, with daily exercises for 8 weeks. The dependent variables were: safety of the technique (periodic telephone monitoring), joint state (Haemophilia Joint Health Score), pain intensity (visual analogue scale), pressure pain threshold (pressure dynamometer), range of motion (universal goniometer) and hamstring flexibility (Fingertip-To-Floor test). The resulting values were measured at baseline (T0) and after the intervention (T1). Paired t-test compared the means between the assessments. Effect size was obtained using Cohen's d mean difference formula. The minimum detectable change of each variable was calculated. RESULTS: There were no cases of joint bleeding either during or after the procedure. The results showed improvements after the experimental period in joint state (Mean difference [MD]: 1.38; 95% confidence interval [95%CI]: .94;1.81), pain intensity (MD: 1.19; 95%CI: .70;1.67), pressure pain threshold (MD: -23.25; 95%CI: -26.25;-19.84), flexion (MD: -4.36; 95%CI: -5.70;-3.01), loss of extension (MD: 4.10; 95%CI: 3.01;5.18) and hamstring flexibility (MD: 3.54; 95%CI: 2.61;4.46). CONCLUSIONS: Myofascial self-release using a foam roller is safe in patients with haemophilic knee arthropathy. A myofascial self-release protocol can improve perceived pain, range of motion and knee joint status, as well as hamstring flexibility in patients with haemophilic knee arthropathy.

RESUMO

BACKGROUND: Recurrent hemarthrosis that begin in childhood lead to progressive joint deterioration. Patients with haemophilia have chronic pain, functional disability and a reduced perception of health-related quality of life. PURPOSE: To analyse the perceived quality of life of adult patients with haemophilic arthropathy and its relationship with pain, joint condition, kinesiophobia and catastrophism. METHODS: Eighty-three adult patients with haemophilia were included in this multicentre, cross-sectional, descriptive study. Perceived quality of life (36-Item Short Form Health Survey), perceived usual and maximum pain (visual analogue scale), joint condition (Haemophilia Joint Health Score), kinesiophobia (Tampa Scale of Kinesiophobia) and catastrophism (Pain Catastrophizing Scale) were assessed. Sociodemographic, clinical and therapeutic variables and drug consumption for pain control were collected. Descriptive statistics used means and standard deviations. The correlation of quality of life with the dependent variables was calculated with the Pearson correlation test. The differences in quality of life as a function of the binomial variables were calculated with Student's t-test for independent samples. RESULTS: Physical component of quality of life perceived by patients with hemophilia is lower than Spanish population (30.51 VS 48.85). Regarding the mental component, patients with hemophilia showed higher values (56.07 VS 49.97). Catastrophism correlated (p < .05) with all items of quality of life questionnaire. Kinesiophobia correlated (p < .05) with all items of quality of life except to role-emotional (r = -.18; p > .05). Habitual and maximal joint pain correlated with all items except to role-emotional (r = - .19 and r = - .09, respectively) and mental component score (r = - .16 and r = - .07, respectively). Catastrophism and weekly drug intake were inversely correlated with quality of life. Age was positively correlated with perceived quality of life. There were differences in quality of life as a function of the severity of haemophilia and the intake of drugs for pain control. CONCLUSIONS: The perceived quality of life of adult patients with haemophilia is worse than that of the Spanish population. Pain, kinesiophobia, catastrophism, haemophilia severity and the intake of pain-control medication influence the quality of life of these patients.

RESUMO

Potato (Solanum tuberosum L.) is the world's most important non-grain food crop and is central to global food security. It is clonally propagated, highly heterozygous, autotetraploid, and suffers acute inbreeding depression. Here we use a homozygous doubled-monoploid potato clone to sequence and assemble 86% of the 844-megabase genome. We predict 39,031 protein-coding genes and present evidence for at least two genome duplication events indicative of a palaeopolyploid origin. As the first genome sequence of an asterid, the potato genome reveals 2,642 genes specific to this large angiosperm clade. We also sequenced a heterozygous diploid clone and show that gene presence/absence variants and other potentially deleterious mutations occur frequently and are a likely cause of inbreeding depression. Gene family expansion, tissue-specific expression and recruitment of genes to new pathways contributed to the evolution of tuber development. The potato genome sequence provides a platform for genetic improvement of this vital crop.

RESUMO

BACKGROUND: Plant resistance genes (R genes) exist in large families and usually contain both a nucleotide-binding site domain and a leucine-rich repeat domain, denoted NBS-LRR. The genome sequence of cassava (Manihot esculenta) is a valuable resource for analysing the genomic organization of resistance genes in this crop. RESULTS: With searches for Pfam domains and manual curation of the cassava gene annotations, we identified 228 NBS-LRR type genes and 99 partial NBS genes. These represent almost 1% of the total predicted genes and show high sequence similarity to proteins from other plant species. Furthermore, 34 contained an N-terminal toll/interleukin (TIR)-like domain, and 128 contained an N-terminal coiled-coil (CC) domain. 63% of the 327 R genes occurred in 39 clusters on the chromosomes. These clusters are mostly homogeneous, containing NBS-LRRs derived from a recent common ancestor. CONCLUSIONS: This study provides insight into the evolution of NBS-LRR genes in the cassava genome; the phylogenetic and mapping information may aid efforts to further characterize the function of these predicted R genes.

RESUMO

OBJECTIVE: Our aim was to determinate the acenocoumarol dose requirement in highly sensitive geriatric patients, based on a minimum of genotype (VKORC1 and CYP2C9) data. METHODS: We used a Gaussian kernel density estimation test to identify patients highly sensitive to the drug and PHARMACHIP®-Cuma test (Progenika Biopharma, SA, Grifols, Spain) to determine the CYP2C9 and VKORC1 genotype. RESULTS: All highly sensitive geriatric patients were taking ≤5.6 mg/week of acenocoumarol (AC), and 86% of these patients presented the following genotypes: CYP2C9*1/*3 or CYP2C9*1/*2 plus VKORC1 A/G, CYP2C9*3/*3, or VKORC1 A/A. CONCLUSION: VKORC1 A and CYP2C9*2 and/or *3 allelic variants extremely influence on AC dose requirement of highly sensitive geriatric patients. These patients display acenocoumarol dose requirement of ≤5.6 mg/week.

RESUMO

Objective: The aim of this investigation was to compare the thickness of the deep local muscles in the neck region, as well as local and widespread sensitivity and functionality, between individuals with migraine, Tension-Type Headache (TTH), and healthy controls. To date, we know that the onset of migraine and TTH share similar pathophysiological pathways. Nevertheless, there may be some anatomical and functional differences which would explain why clinicians may obtain variable results when treating both pathological entities with similar or equal approaches. Methods: An observational study was conducted in accordance with STROBE guidelines. The flexor longus colli and multifidus, two neck-stabilizing muscles, were measured using B-mode ultrasound imaging. The upper trapezius, masseter, temporalis, tibialis anterior, and median nerve all underwent bilateral pressure-pain threshold (PPT) assessments. Results: Ninety participants were enrolled in the study. All subjects were equally divided into TTH, migraine and control groups. The PPT values exhibited lower thresholds in patients with TTH than both migraine and healthy participants. Specifically, in the temporal muscle on both sides, patients with TTH exhibited a significantly lower threshold (p < 0.001)than both migraine and healthy participants. Patients with TTH displayed significantly lower thresholds in both upper trapezius muscles (right: p < 0.001; left: p = 0.001). Similar results were obtained for the tibialis anterior PPTs from both sides (p = 0.001 in both). However, both clinical groups exhibited lower thresholds than the healthy subjects (p < 0.001). In multifidus muscle cross-sectional area (CSA), no statistically significant differences were found between migraine patients and healthy subjects, both in relaxation and contraction (right; p > 0.05 and p > 0.05; left: p > 0.05 and p > 0.05). However, patients with TTH exhibited a smaller CSA than both migraine patients and healthy controls in multifidus relaxed and contracted state (right: p < 0.001 in both relaxed and contracted multifidus; left: p = 0.001 and p < 0.001, respectively). Similar results were obtained for the left longus colli muscle in both relaxation and contraction for patients with TTH and migraine compared with healthy subjects (p = 0.001 and p < 0.001, respectively, for muscle relaxation and p < 0.001 for muscle contraction). However, no significant differences were observed between patients with TTH and migraine (p < 0.05 in both relaxation and contraction). In the right longus colli, TTH and migraine patients had a significantly smaller CSA during contraction than healthy subjects (p < 0.001 in both comparisons). In the craniocervical flexion test, both groups of patients with TTH and migraine showed significantly lower values than healthy subjects (p < 0.001 in both comparisons). However, no significant differences were found between patients with TTH and migraineurs (p > 0.05). Conclusion: The findings provide a significant message for clinicians since anatomical and functional impairments were shown in patients with TTH and migraine. This study corroborates a lack of strength and smaller CSA in both clinical groups compared to controls. Therefore, strengthening programs may be addressed successfully for people with these pathological entities. To be more accurate, according to PPTs and CSA lower values in patients with TTH compared to migraine and controls, manual therapy approaches to desensitize craniocervical soft tissues and exercise therapy to increase endurance of deep cervical muscles may become meaningful especially in subjects with TTH. Nevertheless, in order to distinguish precisely between patients with TTH and migraine, different diagnostic strategies may be used in the future to describe these populations in further detail, which will assist health professionals in a more accurate treatment selection.

RESUMO

Addressing the pressing challenges in agriculture necessitates swift advancements in breeding programs, particularly for perennial crops like grapevines. Moving beyond the traditional biparental quantitative trait loci (QTL) mapping, we conducted a genome-wide association study (GWAS) encompassing 588 Vitis vinifera L. cultivars from a Chilean breeding program, spanning three seasons and testing 13 key yield-related traits. A strong candidate gene, Vitvi11g000454, located on chromosome 11 and related to plant response to biotic and abiotic stresses through jasmonic acid signaling, was associated with berry width and holds potential for enhancing berry size in grape breeding. We also mapped novel QTL associated with post-harvest traits across chromosomes 2, 4, 9, 11, 15, 18, and 19, broadening our grasp on the genetic intricacies dictating fruit post-harvest behavior, including decay, shriveling, and weight loss. Leveraging gene ontology annotations, we drew parallels between traits and scrutinized candidate genes, laying a robust groundwork for future trait-feature identification endeavors in plant breeding. We also highlighted the importance of carefully considering the choice of the response variable in GWAS analyses, as the use of best linear unbiased estimators (BLUEs) corrections in our study may have led to the suppression of some common QTL in grapevine traits. Our results underscore the imperative of pioneering non-destructive evaluation techniques for long-term conservation traits, offering grape breeders and cultivators insights to improve post-harvest table grape quality and minimize waste.

RESUMO

BACKGROUND: Hemophilia is characterized by degenerative joint damage. Patients with hemophilic arthropathy present joint damage, reduced range of motion, and decreased strength and functional capacity. Myofascial release therapy aims to decrease pain and improve tissue mobility and functionality. OBJECTIVES: To evaluate the safety and efficacy of myofascial release therapy in patients with hemophilic ankle arthropathy. METHOD: Single-blind randomized controlled trial. Fifty-eight adult patients with hemophilia were randomly allocated to the experimental group (myofascial release therapy with foam roller) or the control group (no intervention whatsoever). The daily home protocol of myofascial release therapy for the lower limbs using a foam roller lasted eight consecutive weeks. The primary variable was the safety of myofascial release therapy (weekly telephone follow-up). The secondary variables were pain intensity (visual analog scale), range of motion (goniometer), functional capacity (2-Minute Walk Test) and muscle strength (dynamometer), at baseline and at 8 and 10 weeks. RESULTS: During the experimental phase, none of the patients in the experimental group developed ankle hemarthrosis. There were statistically significant changes in time*group interaction in ankle dorsal flexion (F[1.75] = 10.72; p < .001), functional capacity (F[1.16] = 5.24; p = .009) and gastrocnemius strength (F[2] = 26.01; p < .001). The effect size of the changes after the intervention was medium-large in pain intensity (d = -1.77), functional capacity (d = 1.34) and gastrocnemius strength (d = 0.76). CONCLUSION: Myofascial release therapy is a safe form of physical therapy for patients with hemophilia. Myofascial release therapy can effectively complement prophylactic pharmacological treatment in patients with hemophilic arthropathy, improving range of motion in dorsal flexion, functional capacity and gastrocnemius strength.

RESUMO

Objective: This study aimed to evaluate the influence of cigarette smoking habit on the clozapine (CLZ)-to-norclozapine (norCLZ) ratio in male patients. Methods: The sample consisted of plasma concentration of CLZ and norCLZ data set. The mean values of CLZ, norCLZ, and CLZ-to-norCLZ, between male patients who smoke versus nonsmokers were compared. Findings: CLZ mean plasma level of 142 ± 80 ng/ml and 305 ± 159 ng/ml, norCLZ mean plasma level of 93 ± 72 ng/ml and 234 ± 62 ng/ml, and mean CLZ-to-norCLZ plasma level ratio of 2.1 ± 1.1 and 1.5 ± 0.5, were obtained respectively for male patients who smoke and nonsmokers. Conclusion: This study has shown a significant decrease in CLZ and norCLZ plasma levels, and an increase in the CLZ-to-norCLZ ratio, in smokers as compared to nonsmokers, due to an increase in the clearance of CLZ and norCLZ by smoking induction of CYP 1A2 and glucuronidation by uridyl glucuronyl transferase enzymes (UGT), mainly UGT 1A4, respectively, as the most probable cause.

RESUMO

BACKGROUND: Hemophilia is a congenital coagulopathy characterized by degenerative joint damage. Self-induced myofascial therapy aims to decrease pain and improve tissue mobility, functionality and proprioception. AIM: The aim of this study was to evaluate the safety and efficacy of self-induced myofascial release in patients with hemophilic knee arthropathy. DESIGN: This is a randomized clinical study. SETTING: This study was carried out in different patient associations. POPULATION: Fifty-two patients with hemophilia were included in the study. METHODS: Patients were randomized to the experimental group (daily home protocol of foam roller-based self-induced myofascial therapy for 8 weeks) or the control group (no intervention). The variables were the frequency of hemarthrosis (self-reporting), pain intensity (visual analog scale), range of motion (goniometry) and muscle strength (dynamometry). All variables were evaluated at baseline, post-treatment and after a 10-week follow-up. RESULTS: The patients included in the experimental group showed significant improvements in terms of a decrease in frequency of hemarthrosis (mean difference [MD]=-0.61; 95% confidence interval [CI]: -0.81; -0.41) and pain intensity (MD=-0.33; 95% CI: -0.48, -0.18), increased range of motion (MD=0.88; 95% CI: 0.39; 1.37), strength in quadriceps (MD=0.88; 95% CI: 0.39; 1.37). (MD=12.39; 95% CI: 3.44; 21.34) and hamstrings (MD=7.85; 95% CI: 0.60; 15.11). There were intergroup differences in the frequency of hemarthrosis (F=14.51; P<0.001), pain intensity (F=9.14; P<0.001) and range of motion (F=13.58; P<0.001). CONCLUSIONS: Self-induced myofascial therapy can be an effective complementary technique in the treatment of patients with hemophilic arthropathy. Self-induced myofascial therapy can reduce the frequency of knee hemarthrosis in patients with hemophilia. This technique can improve pain intensity and range of motion in patients with hemophilic knee arthropathy. CLINICAL REHABILITATION IMPACT: Hemophilic knee arthropathy is characterized by chronic pain, decreased range of motion, and periarticular muscle atrophy. Foam roller-based self-induced myofascial therapy can reduce the frequency of hemarthrosis and pain intensity and improve range of motion in patients with hemophilic arthropathy. Foam roller-based self-induced myofascial therapy is safe and effective in the treatment of patients with hemophilia. The inclusion of self-induced myofascial therapy exercises in the approach to degenerative joint pathologies may be an effective and safe treatment option.

RESUMO

Objective: The objective of this study is to assess the association between exposure to atorvastatin (ATV) and low-plasma folate (PF) status. Methods: The sample consisted of patients admitted to the internal medicine service of a basic general hospital, located in Zaragoza (Spain). We adopted a pharmacoepidemiological case-control study design. For this, the number of treatment days (TDs) of all the drugs part of their treatment during the study period was obtained from each patient in the sample. The cases were comprised by the number of patient's TDs for which PF ≤3 mg/dl and the controls by the number of patient's TDs for which PF >3 mg/dl. To measure the strength of the association, the odds ratios (ORs) were calculated. The Chi-square test, using the Bonferroni correction, was used to calculate the statistical significance. Findings: The sample consisted of 640 polymedicated patients. The mean PF obtained were 8.0 ± 4.6 mg/dl and 2.1 ± 0.6 mg/dl, for the cases and controls, respectively; the total number of TDs for the cases and controls were 7615 and 57899, respectively. We obtained a U-shaped curve when representing the dose of ATV against the corresponding ORs when comparing cases with control. Conclusion: Exposure to ATV at 10 or 80 mg is associated with an augmented risk of low folate status. We recommend implementing guidelines for mandatory folic acid fortification in patients exposed to ATV doses of 10 or 80 mg.
