Left atrial strain evaluation to assess left ventricle diastolic dysfunction and heart failure with preserved ejection fraction: a guide to clinical practice : Left atrial strain and diastolic function.

Although frequently unrecognized, left atrium (LA) function plays a key role in global cardiac performance as it modulates left ventricle (LV) filling through three main functions: the LA reservoir, conduit and booster pump. Given the interdependence between the LA and the LV, it is known that LA dimension and/or LA function can be used as a surrogate for LV diastolic function.Recently, LA deformation analysis using 2-dimensional (2D) speckle tracking echocardiography (STE) strain emerged as a promising non-invasive technique that can help to estimate LV filling pressures (LVFP) and diagnose heart failure with preserved ejection fraction (HFpEF), as recently proposed in the recent 2022 European Association of Cardiovascular Imaging (EACVI) consensus which included LA reservoir strain as an additive parameter to estimate LVFP.This article aims to review the latest evidence regarding the role of LA strain in the assessment and management of LV diastolic dysfunction (LVDD) and HFpEF, providing a clinical guide with tips and tricks to use LA strain as a new technique to help to estimate LVFP.

A Systematic Review and Meta-analyses of Longitudinal Studies on Drug Treatments for Gaucher Disease.

OBJECTIVE: Gaucher disease (GD) is a rare disorder linked to the absence/deficiency of glucocerebrosidase. GD can be treated by enzyme replacement therapy (ERT) and substrate reduction therapy (SRT). The aim of this systematic review (SR) is to assess the effectiveness of drugs used for GD treatment. DATA SOURCES: Searches were conducted in PubMed and Scopus, in April 2021. The search strategies encompassed the name of the disease and of the drug treatments. Manual search was also conducted. STUDY SELECTION AND DATA EXTRACTION: Observational and interventional longitudinal studies evaluating ERT and SRT for GD were included. Single mean meta-analyses were conducted for each drug using R. DATA SYNTHESIS: The initial search retrieved 2246 articles after duplicates were removed. Following screening and eligibility assessment, 68 reports were included. The studies evaluated imiglucerase, velaglucerase alfa, taliglucerase alfa, miglustat, and eliglustat. The results showed that ERT is effective as a treatment in both naïve and experienced patients. Miglustat did not significantly improve blood outcomes in naïve patients and resulted in a decrease in the platelet levels of experienced patients. Eliglustat was mainly assessed for experienced patients and resulted in stable outcome values. RELEVANCE TO PATIENT CARE AND CLINICAL PRACTICE: This extensive SR confirms the effectiveness of GD treatments in short- and long-term follow-ups. CONCLUSIONS: The results were favorable for all ERTs and for eliglustat. Based on the assessed evidence, miglustat did not achieved expressive results. However, all evidence should be interpreted considering its limitations and does not replace well-conducted randomized trials.

Catastrophic presentation of peripartum cardiomyopathy: a case report of a challenging diagnosis.

Background: Peripartum cardiomyopathy (PPCM) usually affects women in the last month of pregnancy or in the first months following delivery and typically presents with signs and symptoms of heart failure (HF), although catastrophic presentations may be the initial manifestation. Case summary: A 36-year-old woman reported intense fatigue that began after delivery. Three months following delivery, she suffered a cardiac arrest at home, in shockable rhythm, with a total estimated time of 70 min before return of spontaneous circulation. Electrocardiogram presented diffuse ST-segment depression and transthoracic echocardiography showed severe left-ventricle (LV) dysfunction with global hypokinesis. In the catheterization laboratory, she underwent a triple rule out (no aortic, coronary, or pulmonary vascular disease); ventriculography was not suggestive of Takotsubo syndrome. She was transferred to the cardiac intensive care unit, under invasive mechanical ventilation and vasopressor support. A presumptive diagnosis of PPCM was made and bromocriptine and heparin were started. In three days, she was weaned from haemodynamic support and extubated, with good neurologic outcome. Cardiac magnetic resonance showed no signs of inflammation or fibrosis. Cardiomyopathy genetic test was negative. PPCM diagnosis was assumed, HF therapy was introduced and a cardioverter-defibrillator was implanted. At 2.5 months follow up, she presented HF NYHA Class II and recovered LV function. Discussion: We present a case of a woman, three months after delivery, who developed a catastrophic manifestation of PPCM. This case raises awareness about atypical presentations of PPCM, whose diagnosis should be considered in the appropriate clinical context, but ultimately, remains a diagnosis of exclusion.

Randomized Clinical Trial of Water-Based Aerobic Training in Older Women (WATER Study): Functional Capacity and Quality of Life Outcomes.

BACKGROUND: The purpose of this study was to investigate the effects of 2 water-based aerobic training programs on functional capacity and quality of life (QoL) of older women. DESIGN: Randomized clinical trial. METHODS: A total of 41 women (64.3 [3.1] y) were randomized into a continuous (CTG) and an interval (ITG) water-based aerobic training group. Training programs were performed with exercise intensity based on rating of perceived exertion throughout 12 weeks (twice a week). Functional tests with and without dual-task and QoL questionnaire were applied pretraining and posttraining. Per protocol and intention to treat analysis were conducted using generalized estimating equations, with Bonferroni post hoc test (α = .05). RESULTS: The per protocol analysis showed an increase in the 30-second chair stand (6% [12%] vs 18% [13%]), 6-minute walk (4% [7%] vs 2% [8%]), and 5-m habitual gait velocity (6% [11%] vs 4% [7%]) tests after CTG and ITG training groups. In addition, the intention to treat analysis revealed an increase in the 30-second chair stand test (7% [13%] vs 12% [13%]) and physical domain of QoL (8% [26%] vs 14% [22%]) after CTG and ITG training groups, as well as an increase in the gait velocity with verbal task after CTG (6% [11%]). CONCLUSIONS: Both water-based aerobic training programs induced similar improvements in the functional capacity and maintained the QoL perception in older women.

Water-based continuous and interval training in older women: Cardiorespiratory and neuromuscular outcomes (WATER study).

The purpose of this study was to investigate the effects of two water-based aerobic programs on cardiorespiratory and neuromuscular outcomes in older women. Forty-one women (60 to 75 years old) volunteered to participate in the study. Participants were randomized into a water-based continuous (CTG; n = 21; 63.9 ± 2.5 years) or an interval (ITG; n = 20; 64.8 ± 3.6 years) aerobic training group. Both training programs were performed for 12 weeks (45-min sessions twice a week), with exercise intensity based on rating of perceived exertion (Borg's RPE 6-20 Scale). Pre and post training assessments of cardiorespiratory and neuromuscular outcomes were performed. Data analyses were conducted using Generalized Estimating Equations and Bonferroni post-hoc test (α = 0.05). After the intervention, the CTG and the ITG displayed similar improvements in time to exhaustion (8% vs. 11%), peak oxygen uptake (9% vs. 7%), maximal dynamic knee extension strength (5% vs. 6%), dynamic muscular endurance of knee extensors (10% vs. 11%), maximal vastus lateralis electromyographic signal amplitude (13% vs. 35%), as well as an increase in muscle thickness (5% vs. 6%) and decrease in muscle echo intensity (-2% vs. -3%) of the quadriceps femoris. In conclusion, older women benefited from water-based exercise training prescribed based on participants' RPE, with both the interval and the continuous training programs resulting in similar increases in the cardiorespiratory and neuromuscular parameters.

Water-based aerobic and combined training in elderly women: Effects on functional capacity and quality of life.

This study aimed to investigate the effects of two water-based training programs (aerobic and combined) and a non-periodized physical activity program on functional capacity and quality of life (QoL) of elderly women. Forty-one elderly female volunteers (65 ±â€¯4 years) were divided into three groups: aerobic training group (WBA, n = 13), combined training (sequence: resistance/aerobic; WBC; n = 11) and a control group of non-periodized physical activity program (CG, n = 9). The participants performed the water-based trainings twice a week for 12 weeks. The resistance training sets were performed at maximal effort and the aerobic training was performed in the percentage of the heart rate corresponding to the anaerobic threshold (85-110%) determined in an aquatic progressive test. Assessments of QoL perception (WHOQOL-BREF) and functional tests 30-Second Chair Stand, 6-Minute Walk and 8-Foot Up-and-go were performed before and after training. The data were analyzed using Generalized Estimating Equations (GEE), and Bonferroni post-hoc test (α = 0.05). In CG, QoL perception in the physical domain decreased (12 ±â€¯10%) and there was no difference in the other domains. On the other hand, QoL perception was significantly increased in the water-based training groups after the training period in the physical (WBC: 13 ±â€¯16%), psychological (WBA: 9 ±â€¯16%; WBC: 10 ±â€¯11%), social relationships (WBA: 19 ±â€¯42%; WBC: 16 ±â€¯21%) and environmental (WBA: 10 ±â€¯17%; WBC: 16 ±â€¯28%) domains and overall QoL (WBA: 17 ±â€¯22%). No significant difference was observed in the physical domain for WBA and in the overall for WBC. Significant improvements were observed for all groups in the functional tests 30-Second Chair Stand (WBA: 32 ±â€¯11%; WBC: 24 ±â€¯14%; CG: 20 ±â€¯9), 6-Minute Walk (WBA: 10 ±â€¯7%; WBC: 7 ±â€¯6%; CG: 7 ±â€¯5%) and 8-Foot Up-and-go (WBA: 11 ±â€¯5%; WBC: 10 ±â€¯9%; CG: 10 ±â€¯6%). Based on the results observed in this study, it can be concluded that both water-based trainings (aerobic and combined) are effective in improving functional capacity and QoL perception of elderly women. Although non-periodized physical activities seem to be sufficient to positively modify the functional capacity of this population, they are not efficient in improving QoL perception.

Prevalence of Hypertrophic Cardiomyopathy in Fetuses of Mothers with Gestational Diabetes before Initiating Treatment.

Objective To evaluate the prevalence of hypertrophic cardiomyopathy (HCM) in fetuses of pregnant women with gestational diabetes mellitus (GDM) in the beginning of the treatment.

RESUMO Objetivo: Avaliar a prevalência de miocardiopatia hipertrófica em fetos de gestantes com diabetes mellitus gestacional antes do início do tratamento. Métodos: Foi realizado um estudo de corte transversal, no período de 1o de julho de 2013 até 20 de dezembro de 2013, em uma maternidade pública. Foram objetos do estudo 63 fetos de gestantes portadoras de diabetes mellitus gestacional (DMG), em gestação única e sem outras patologias associadas. Foi realizada ecocardiografia fetal antes do início do tratamento do diabetes. O diagnóstico de miocardiopatia hipertrófica (MH) foi realizado quando a medida do septo interventricular ou da parede ventricular estava superior a dois desvios-padrão. O desfecho primário avaliado foi presença de MH. Resultados: As gestantes apresentavam idade média de 32,32 (±6,2) anos, e a idade gestacional média no momento da avaliação foi de 30,59 (±2,27) semanas. A medida do septo interventricular estava acima de 2 desvios-padrão em 50,8% (intervalo de confiança de 95% [IC95%]: 38,1-63,5%). A parede do ventrículo esquerdo estava acima de 2 desvios-padrão em 13 fetos, totalizando 20,6% (IC95%: 11,1-30,2%). A MH estava presente em 54% dos fetos (IC95%: 41,3-65,1%). A circunferência abdominal fetal estava normal em 46 (73%) fetos, e destes, 50% apresentavam MH. Conclusão: A prevalência de MH em fetos de gestantes portadoras de DMG antes do tratamento foi de 54% (IC95% 41,3-65,1%).

[Preterm birth susceptibility: investigation of behavioral, genetic, medical and sociodemographic factors]. / Suscetibilidade à prematuridade: investigação de fatores comportamentais, genéticos, médicos e sociodemográficos.

PURPOSE: To investigate the association between genetic, behavioral, biological and medical risk factors and the occurrence of preterm birth. METHODS: A retrospective case-control study was conducted. The real-time polymerase chain reaction was used to analyze the influence of the rs12473815 polymorphism of the follicle stimulating hormone receptor gene (FSHR) and the rs1942836 polymorphism of the progesterone receptor gene (PGR). Other proposed risk factors were assessed using validated or specifically developed questionnaires and analysis of electronically recorded medical data. A total of 157 patients were included (45 cases who went into labor before 37 weeks of pregnancy and 112 controls who went into labor after 37 and before 42 weeks of pregnancy). RESULTS: The genotypes CT of rs12473815 and CT and CC of rs1942836 were associated with a higher chance of premature delivery. There was an association between preterm birth and alcohol intake when consumption occurred 2 or more times per month. Low pre-pregnancy body mass index was a predictor of spontaneous preterm birth, while high body mass index reduced this likelihood. CONCLUSIONS: The results suggest that excessive alcohol intake, a low level of pre-pregnancy body mass and the risk alleles of rs12473815 and rs1942836 polymorphisms of the FSHR and PGR genes, respectively, influence the occurrence of preterm birth.

[Obesity during pregnancy: gestational complications and birth outcomes.] / Obesidade durante a gravidez: resultados adversos da gestação e do parto.

PURPOSE: To evaluate the influence of maternal obesity on pregnancy, childbirth, and neonatal outcomes. METHODS: A cross-sectional study with 298 postpartum women. Information was obtained through interviews and access to patients' medical records. The patients were divided into three groups according to their pre-gestational body mass index: normal weight (18.5-24.9 kg/m2), overweight (25.0-29.9 kg/m2), and obese (≥30.0 kg/m2). Data are reported as adjusted odds ratios with 95% confidence interval (95%CI) following multinomial logistic regression analysis to account for confounding variables. RESULTS: Compared to pregnant women with normal body mass index, overweight women had greater chances of having cesarean delivery, odds ratio (OR) of 2.2 and 95%CI 1.3-3.9, and obese women even more (OR=4.2; 95%CI 2.1-8.1). The chances of gestational diabetes increased in the Overweight (OR=2.5; 95%CI 1.1-5.6) and Obese groups (OR=11.1; 95%CI 5.0-24.6). The occurrence of hypertensive syndrome was also higher in overweight (OR=3.2; 95%CI 1.2-8.1) and obese pregnant women (OR=7.5; 95%CI 2.9-19.1). Major postpartum hemorrhage only showed greater values in the obese women group (OR=4.1; 95%CI 1.1-15.8). Regarding the newborns, the probability of a low Apgar score at first minute was higher in the Obese Group (OR=5.5; 95%CI 1.2-23.7) and chances of macrosomia were higher in the Overweight Group (OR=2.9; 95%CI 1.3-6.3). Data regarding neonatal hypoglycemia were not conclusive. CONCLUSION: Excessive weight (overweight and obesity) during pregnancy increases the chance of maternal complications (gestational diabetes, hypertensive syndrome, and major postpartum hemorrhage) and neonatal outcomes (cesarean delivery, macrosomia, and low Apgar score).

Obesidade durante a gravidez: resultados adversos da gestação e do parto / Obesity during pregnancy: gestational complications and birth outcomes

OBJETIVO: Avaliar a influência do excesso de peso materno na gestação, no parto e nos desfechos neonatais. MÉTODOS: Estudo transversal e retrospectivo que incluiu 298 puérperas. As informações foram obtidas por meio de entrevistas e acesso aos prontuários das pacientes. As puérperas foram divididas em três grupos, conforme o índice de massa corpórea pré-gestacional: normal (18,5–24,9 kg/m2); sobrepeso (25,0–29,9 kg/m2) e obesidade (≥30,0 kg/m2). Foram construídos modelos de regressão logística multinominal para ajustar o efeito das variáveis de confusão. Estabeleceram-se intervalos de confiança de 95% (IC95%). RESULTADOS: Comparadas às gestantes com peso normal, pacientes com sobrepeso apresentaram chances maiores de cesariana, sendo a odds ratio (OR) de 2,2 e IC95% 1,3–3,9, e as obesas tiveram ainda maiores (OR=4,2; IC95% 2,1–8,1). As chances de desenvolvimento de diabetes gestacional aumentaram nos grupos Sobrepeso (OR=2,5; IC95% 1,1–5,6) e Obesidade (OR=11,1; IC95% 5,0–24,6). A síndrome hipertensiva na gravidez também se mostrou mais provável nas gestantes com sobrepeso (OR=3,2; IC95% 1,2–8,1) e obesas (OR=7,5; IC95% 2,9–19,1). A hemorragia de grande porte no momento do parto somente apresentou maiores valores no grupo de obesas (OR=4,1; IC95% 1,1–15,8). Quanto aos recém-nascidos, a probabilidade de Apgar baixo no primeiro minuto foi superior entre as obesas (OR=5,5; IC95% 1,2–23,7), e a ocorrência de macrossomia aumentou nas mulheres com sobrepeso (OR=2,9; IC95% 1,3–6,3). Os resultados quanto à hipoglicemia neonatal não foram conclusivos. CONCLUSÃO: As chances de intercorrências maternas (diabetes gestacional, síndrome hipertensiva, hemorragia pós-parto) e neonatais (cesariana, macrossomia e escore Apgar ...

Parâmetros a serem considerados no tratamento e controle do Diabetes Gestacional / Parameters to be considered in the treatment and control of Gestational Diabetes

O diabetes gestacional é uma doença metabólica crônica, cuja principal característica é a resistência insulínica, que repercute na morbidade materna e nos desfechos perinatais. Sua prevalência no Brasil está em torno de 7 a 10%. Quando utilizados valores glicêmicos mais baixos do que aqueles anteriormente propostos, um grupo maior de gestantes é enquadrado no diagnóstico desta doença, contribuindo para aumento de sua incidência. Diante deste fato e dos diversos efeitos adversos do diabetes, como hiperinsulinemia fetal e macrossomia, é necessário instituir uma terapêutica rápida e eficaz. A decisão em iniciar esta terapêutica baseia-se em conceitos sabidamente conhecidos, tais como valores glicêmicos de controle, estudo ecográfico fetal (medida da circunferência abdominal), idade gestacional e obesidade materna. Neste trabalho, esses conceitos foram discutidos após uma revisão dos artigos atuais e de maior relevância cientifica.(AU)

The gestational diabetes is a metabolic chronic disorder which main feature is the insulin resistance and its consequences as maternal morbidity and perinatal outcomes. The prevalence in Brazil is from 7 to 10%. When we use lower targets of glycemic control than those previously used, a greater group of pregnants fits into the diagnosis of diabetes, and thereby increasing the incidence of the disease. Towards this and the several adverse outcomes, as fetal hyperinsulinemia and macrossomia, an early and effective treatment has to be established. The decision in begin the therapy is based on elements already known, as the glycemic targets, fetal ultrasound (abdominal circumference measure), gestational age and maternal obesity. These elements are discussed in this paper after a literature review of the latest and more scientific important articles.(AU)

Objetivo: Avaliar, com base nas publicações nacionais e internacionais, as consequências da obesidade materna na gestação, no parto e nos desfechos neonatais. Métodos: Revisão sistemática da literatura sobre obesidade na gravidez nas bases MEDLINE, LILACS, Embase e Cochrane. Os desfechos avaliados foram intercorrências maternas, intercorrências no parto e desfechos neonatais. Resultados e discussão: Dentre os 10.815 artigos inicialmente selecionados entre junho e dezembro de 2013, somente 23 estavam de acordo com os critérios estabelecidos. Desses, 1 apresentou grau de evidência A, 13 apresentaram B e 9 artigos, níveis de evidência C ou D. A maior parte das publicações selecionadas era referente às intercorrências maternas e no parto. Entretanto, o maior nível de evidência foi encontrado nos trabalhos que discorreram sobre desfechos neonatais. Conclusão: A obesidade materna está associada ao aparecimento de distúrbios endócrinos, cardiovasculares e ocorrência de parto instrumental. Os desfechos neonatais incluem malformações congênitas, escore Apgar baixo, macrossomia e morte neonatal.(AU)

Background: The maternal overweight occurs in 25-30% of pregnancies in Brazil. However, only recently have been evaluated the impact of obesity on pregnancy outcomes. Objective: To evaluate, based on national and international publications, the consequences of maternal obesity in pregnancy, childbirth and neonatal outcomes. Methods: A systematic review of the literature on obesity in pregnancy in MEDLINE, LILACS, Embase and Cochrane library. The outcomes assessed were maternal disorders, complications in childbirth and neonatal outcomes. Results and discussion: Among 10,815 articles initially selected between June and December 2013, only 23 were in accordance with the criteria set. Of these, 1 presented level of evidence A, 13, level of evidence B, and 9 articles, levels of evidence C or D. Most of the selected publications were referring to maternal complications and delivery. However, publications with the highest level of evidence assessed neonatal outcomes. Conclusion: Maternal obesity is associated with development of endocrine disorders, cardiovascular events and occurrence of instrumental delivery. Neonatal outcomes include congenital malformations, low Apgar scores, macrosomia and neonatal death.(AU)

Preditores de sucesso da metformina no tratamento do diabetes mellitus gestacional / Predictors of success of metformin treatment of diabetes mellitus in pregnancy

Identificar características maternas relacionadas à falha no tratamento do diabetes mellitus gestacional (DMG) com metformina. MÉTODOS: estudo retrospectivo observacional (julho/2008-setembro/ 2010), com 104 gestantes com DMG que necessitaram de terapêutica complementar a dietoterapia e utilizaram metformina. Dividiram-se em dois grupos: sucesso terapêutico (n=82), onde a droga foi mantida até o parto; outro com falha terapêutica (n=22) onde a droga foi substituída por insulina. Variáveis maternas estudadas: idade, número de partos, ganho de peso na gestação, glicemia de jejum (GJ) e 2h no OGTT75g, idade gestacional de diagnóstico de DMG (IGDMG). Variáveis do recém nascido: incidência de RNs GIG e hipoglicemia neonatal. Foram comparadas as características clínico-metabólicas maternas e os resultados perinatais, o nível de significância utilizado foi de 5 por cento. RESULTADOS: apresentaram diferença na IGDMG (27,5 vs 24,3 semanas; p=0,02), no índice de massa corporal (IMC) (27,5 vs 31,6 kg/m²; p=0,01), e GJ no OGTT75g (91,5 vs 108 mg/dL; p=0,02), nos grupos de sucesso e falha respectivamente. A falha terapêutica aumentou o índice ponderal dos RNs (2,8 vs 3 g/cm³; p=0,05), incidência de RNs GIG (4,9 vs 22,7 por cento; p=0,02) e hipoglicemia neonatal (6,1 vs 18,2 por cento; p=0,04). Os dados dos RNs foram objetivos secundários. CONCLUSÕES: o diagnóstico precoce, o maior IMC e maior GJ OGTT75g estiveram mais relacionados a falha terapêutica...

To identify characteristics of the mother related to failure of treatment of diabetes mellitus in pregnancy using metformin. METHODS: an observational retrospective study (July 2008- September 2010), with 104 pregnant women with pregnancy-related diabetes mellitus needing therapy to complement dietary treatment and using metformin. The women were divided into two groups: successful treatment (n=82), where the drug was maintained up to delivery; treatment failure (n=22) where the drug was replaced by insulin. The maternal variables studied were age, number of deliveries, weight gain during pregnancy, fasting glycaemia and two hours after OGTT75g, gestational age on diagnosis of diabetes mellitus. Variables relating to the newborn were incidence of GIG and neonatal hypoglycaemia. The clinical and metabolic characteristics of the mother and perinatal results were compared. The level of significance used was 5 percent. RESULTS: there were diferences in the gestational age on diagnosis of diabetes melittus (27.5 vs 24.3 weeks; p=0.02), body mass index (BMI) (27.5 vs 31.6 kg/m²; p=0.01), and fasting glycaemia on OGTT75g (91.5 vs 108 mg/dL; p=0.02), in the treatment success and failure groups, respectively. Treatment failure increased the weight index of newborns (2.8 vs 3 g/cm³; p=0.05), the incidence of GIG in RNs (4.9 vs 22.7 percent; p=0.02) and neonatal hypoglycaemia (6.1 vs 18.2 percent; p=0.04). The data on newborns were secondary objectives. CONCLUSIONS: early diagnosis, higher BMI and higher fasting glycaemia OGTT75g were more related to treatment failure...
