Glioma tectal pediátrico con hidrocefalia y ventriculomegalia. Dos casos clínicos / Pediatric tectal glioma presented with acute hydrocephalus and ventriculomegaly. Two case reports

Los gliomas tectales representan un subtipo de tumores de bajo grado que se desarrollan en la región tectal, en la parte superior del tronco encefálico. Los síntomas incluyen los causados por el aumento de la presión intracraneal por hidrocefalia obstructiva. Son comunes la cefalea, la visión borrosa o doble, las náuseas y los vómitos. El tratamiento de la hidrocefalia es la ventriculostomía endoscópica del tercer ventrículo o la derivación ventrículo-peritoneal. Los gliomas tectales se diagnostican habitualmente en la infancia, pero son frecuentes también en adultos. En general son benignos y de progresión lenta; es suficiente el seguimiento ambulatorio clínico y radiológico. Se presentan dos pacientes pediátricos con tumores de la placa tectal mesencefálica. Un niño de 11 años y una niña de 15 años concurrieron al Departamento de Emergencias con diferentes síntomas. El niño fue tratado con derivación ventrículo-peritoneal por hidrocefalia aguda.

Tectal gliomas represent a subset of low-grade tumors that arise in the tectal region at the roof of the brainstem. Symptoms of tectal glioma include those caused by increased intracranial pressure due to obstructive hydrocephalus. Headache, blurred vision, double vision, nausea and vomiting are common symptoms. In the treatment, ETV (endoscopic third ventriculostomy) or VP-shunt (ventriculoperitoneal) can be applied to treat hydrocephalus. Tectal gliomas are usually diagnosed in childhood and often occur in adults. They are often benign, slowly progressing lesions; outpatient clinical and radiological followup is sufficient. We present two cases of pediatric patients with mesencephalic tectal plate tumors. An 11-year-old boy and a 15-year-old girl applied to the Emergency Department with different complaints. The 11 year-old-boy was treated with VP-shunt due to acute hydrocephalus.

[Factors associated with normal leukocyte count and C-reactive protein in adults with acute appendicitis: a retrospective cohort study]. / Faktory, svyazannye s normal'nym kolichestvom leikotsitov i urovnem S-reaktivnogo belka u vzroslykh bol'nykh s ostrym appenditsitom: retrospektivnoe kogortnoe issledovanie.

OBJECTIVE: To identify the factors associated with normal leukocyte count and C-reactive protein (CRP) in adults with acute appendicitis. MATERIAL AND METHODS: A retrospective cohort study included patients aged 18-60 years after surgeries for acute appendicitis. Convenience sampling was used to select medical records, and variables such as age, sex, weight, height, origin, self-medication, diabetes (DM2), high blood pressure (HBP), type of appendicitis, duration of illness, preoperative time, type of appendectomy, operative time, and hospital stay were analyzed. Patients were categorized into those with normal and abnormal inflammatory parameters. The SPSS version 28 software was used for analysis. RESULTS: We included 333 patients; 11.11% ones had normal inflammatory parameters. Both groups had mean age of approximately 33 years. Men comprised 56.76% and 57.43%in both groups, respectively. The abnormal group had shorter mean preoperative time, and catarrhal appendicitis was more common in the normal group. Multivariate analysis revealed that rural origin and self-medication were significantly associated with normal inflammatory parameters. CONCLUSION: The prevalence of normal inflammatory parameters in acute appendicitis patients was 11.11%. Rural origin, self-medication, shorter preoperative time, and catarrhal appendicitis were significantly associated with normal inflammatory parameters in this context.

[Right-sided acute appendicitis in situs inversus totalis. Case report]. / Apendicitis aguda del lado derecho en situs inversus totalis. Reporte de caso.

Background: Acute appendicitis is widely recognized as the prevailing abdominal surgical emergency globally, exhibiting an annual incidence ranging from 96.5 to 100 cases per 100,000 adults. Conversely, situs inversus totalis is a rare anatomical anomaly characterized by the complete reversal of the chest and abdominal organs, occurring in approximately 1 out of every 10,000 to 50,000 individuals. Clinical case: 53-year-old female patient who presented to the emergency department with a complaint of diffuse abdominal pain of colic nature that had persisted for 5 days. The patient referred systemic hypertension, pre-diabetes mellitus type 2, and situs inversus as relevant medical history. A laparotomy procedure was conducted, revealing a perforated appendix located in the right hypochondrium. Additionally, the patient exhibited situs inversus totalis, with the colon positioned in its normal anatomical location. Conclusions: Due to the low incidence of situs inversus totalis, in cases similar to the one presented, the utilization of image studies and laboratory studies is imperative for accurate diagnosis. In the face of diagnostic suspicions and inconclusive paraclinical studies, the most effective approach is to pursue surgical examination and intervention, preferably utilizing laparoscopic techniques.

Introducción: la apendicitis aguda es la urgencia quirúrgica abdominal más frecuente en el mundo, con una incidencia anual de 96.5 a 100 casos por 100,000 adultos. Por otra parte, el situs inversus totalis es un trastorno posicional inverso de los órganos torácicos y abdominales con una incidencia de 1 en 10,000 a 50,000 personas. Caso clínico: paciente del sexo femenino de 53 años que se presentó en sala de urgencias refiriendo dolor abdominal difuso tipo cólico de 5 días de evolución. La paciente refirió hipertensión arterial sistémica esencial, prediabetes mellitus tipo 2 y situs inversus. Se realizó intervención quirúrgica (laparotomía) en la que se encontró el apéndice perforado en hipocondrio derecho y situs inversus totalis con colon en posición anatómica normal. Conclusiones: debido a la baja incidencia del situs inversus totalis, el diagnóstico en casos como el presentado representa un reto en el que el uso de estudios de imagen y laboratorio resulta indispensable. Ante la sospecha diagnóstica y estudios paraclínicos con resultados no concluyentes, la mejor estrategia consiste en la exploración y el manejo quirúrgicos, preferentemente laparoscópicos.

EPIDEMIOLOGY OF DEPRESSIVE STATES IN ACUTE AND CHRONIC CONDITIONS.

Depression is the only silent cause that mainly affects the adult population and manifests itself in this case in 4% of the world population. However, more than three quarters of those affected belong to land in urbanization without receiving any type of treatment; a situation that represents a gap in access to mental health services. Now, the hallucinatory relationships mean that this condition has a high level of competition with chronic diseases such as HIV, diabetes, lung disease, asthma, arthritis, angina pectoris and cerebral palsy; Assimilation, it has been detected that patient with affective disorders such as coronary syndrome, inflammation, malnutrition, pain, stress and even critical stages of COVID-19 infection act as risk factors for the development of the disease. In this context, as a result of concern for public health, particularly in countries following the crisis, this study presents a proposal to carry out a review regarding the prevalence of depression in the presence of aggravated cases and crises. Strategies are implemented to address this situation. For this, a systematic review of the literature was carried out, complemented with bibliometric data on scientific contributions, with a period of 10 years (2011-2021) registered in the databases: Web of Science, Scopus and PubMed. In this way, the results allowed us to identify that, in recent years, in the fight to combat this problem, various remedies were used for its treatment and prevention; in which the focus is on the modification of health behaviors and collaborative care, which seeks quality of life in cases of patients with chronic diseases. On the other hand, the bibliometric information allows us to determine that the United States, Australia and Canada are the countries with the greatest scientific production on the subject. It is concluded that, although health services have demonstrated and improved their strategies in recent years, and that part of them have been supported by technological innovation, there are bridging markets at the cultural and socioeconomic level that the treatment and primary care of these patients.

[Strategie of the "acute respiratory disease room" in two tertiary referral clinics: a retrospective multicenter cohort study]. / Estrategia de "sala enfermedad respiratoria aguda" en dos clínicas de referencia de tercer nivel de complejidad: estudio de cohorte multicéntrica retrospectiva.

Respiratory diseases are one of the main causes of morbidity and mortality in children under 5 years of age. The acute respiratory disease (ERA in Spanish) room strategy implemented in Colombia is an important tool to reduce hospitalization and mortality rates in this population. OBJECTIVE: To describe the health outcomes of the implementation of the ERA room strategy in two health institutions in Bogota. PATIENTS AND METHOD: Multicenter descriptive study including 1785 patients admitted to the ERA rooms of two institutions in Bogota, between December 2019 and 2022. Data on sex, age, admission diagnosis, length of stay in ERA room, education provided, and post discharge follow-up were collected. The main outcomes were evaluated through hospitalization requirement, ICU requirement, and post discharge improvement. RESULTS: 1785 patients were included during the study period. 57% were male; median age was 26.6 months (IQR: 11.8 to 40.6); length of stay in ERA room was 2.62 hours (IQR: 1.73 to 4.88); 91.65% of family members and/or caregivers received educational measures. CONCLUSIONS: This study describes the results of the implementation of the ERA room strategy; the low proportion of patients requiring hospitalization is evident. Additionally, the education provided to parents and caregivers on home management is relevant, as well as the post discharge follow-up of this cohort of patients with acute respiratory disease.

Epidemiology and molecular detection of human adenovirus and non-polio enterovirus in fecal samples of children with acute gastroenteritis: A five-year surveillance in northern Brazil.

Acute gastroenteritis (AGE) is a common pediatric infection that remains a significant cause of childhood morbidity and mortality worldwide, especially in low-income regions. Thus, the objective of this study was to detect human adenovirus (HAdV) and non-polio enterovirus (NPEV) in fecal samples from the Gastroenteritis Surveillance Network, and to identify circulating strains by nucleotide sequencing. A total of 801 fecal samples were tested using qPCR/RT-qPCR, and 657 (82.0%) were inoculated into HEp-2C and RD cell lines. The HAdV and NPEV positivity rates obtained using qPCR/RT-qPCR were 31.7% (254/801) and 10.5% (84/801), respectively, with 5.4% (43/801) co-detection. Cytopathic effect was observed in 9.6% (63/657) of patients, 2.7% (18/657) associated with HAdV, and 6.2% (41/657) associated with NPEV after testing by ICC-PCR. A comparison of the two methodologies demonstrated an agreement of 93.5% for EVNP and 64.4% for HAdV. These two viruses were detected throughout the study period, with HAdV positivity rates ranging from 41% in Amapá to 18% in Pará. The NEPV varied from 18% in Pará/Rondônia to 3% in Acre. The most affected age group was over 60 months for both HAdV and NPEV. Samples previously positive for rotavirus and norovirus, which did not show a major difference in the presence or absence of diarrhea, fever, and vomiting, were excluded from the clinical analyses of these two viruses. These viruses circulated over five years, with a few months of absence, mainly during the months corresponding to the waves of SARS-CoV-2 infection in Brazil. Five HAdV species were identified (A, B, C, D, and F), with a greater predominance of HAdV-F41 (56.5%) followed by HAdV-C (15.2%). Three NPEV species (A, B, and C) were detected, with serotypes E14 (19.3%) and CVA-24 (16.1%) being the most prevalent. The present study revealed a high diversity of NPEV and HAdV types circulating in children with AGE symptoms in the northern region of Brazil.

Efficacy of routine second-look endoscopy after endoscopic hemostasis in patients with acute peptic ulcer bleeding: systematic review and meta-analysis.

OBJECTIVE: To evaluate the efficacy of scheduled second-look endoscopy in patients with acute peptic ulcer bleeding (PUB). MATERIALS AND METHODS: We systematically search in four databases for randomized controlled trials (RCTs) that evaluated the usefulness of scheduled second-look endoscopy vs. single endoscopy in patients with PUB. Our primary outcome was rebleeding. Secondary outcomes were surgery, mortality, and the number of units of blood transfused (NUBT). All meta-analyses were performed using a random-effects model. Pooled risk ratio (RR) and mean difference (MD), with their 95% confidence intervals (CIs) were calculated for categorical and continuous outcomes, respectively. The risk of bias was assessed using the Cochrane RoB 2.0 tool, and the quality of evidence (QoE) was rated with the GRADE approach. RESULTS: Eight full-text RCTs and two RCT abstracts were included (n=1513). We did not find differences in rebleeding (RR, 0.78; 95% CI, 0.53-1.14, moderate QoE), surgery (RR, 0.58; 95% CI, 0.29-1.15, moderate QoE), mortality (RR, 0.89; 95% CI, 0.46-1.71, moderate QoE) or NUBT (MD, -0.01 units; 95% CI, -0.3 to 0.28, low QoE) between second-look and single endoscopy. Sensitivity analyses had similar results to the main analyses. CONCLUSIONS: Routine second-look endoscopy was not more efficacious than single endoscopy in patients with PUB.

FASTING INCREASES THE SEVERITY OF ACUTE PANCREATITIS IN A MOUSE MODEL: IMPLICATIONS FOR PREOPERATIVE INTERVENTIONS TO REDUCE COMPLICATIONS OF PANCREATIC SURGERY.

BACKGROUND: Acute pancreatitis following surgical or endoscopic procedures on the pancreas can compromise the outcome and lead to severe complications and even death. The aim of this study was to determine whether prolonged fasting affects the severity of acute pancreatitis (AP). METHODS: Male mice were divided into 4 groups: Group CF (n=5) control animals that fasted for 24 hours; Group CNF (n=5) control animals that did not fast; Group APF (n=7) that fasted for 24 hours and underwent induction of acute pancreatitis (AP) and Group APNF (n=7) that did not fast and underwent AP. Eight hours after AP blood was collected for evaluation of cytokines: IL-1ß, IL-6, IL-10, TNF-α and MCP-1. Liver tissue was collected for determination of Malondialdehyde, pancreatic tissue for determination of enzyme content and lung tissue for determination of myeloperoxidase. RESULTS: Significant increase in pancreatic amylase content was observed in group CF and increased serum levels of IL -6, Il-10 and MCP-1 were in group APF. Liver malondialdehyde was also increased in APF animals. APF group showed much more necrosis of the pancreatic acinar cells. CONCLUSION: In the present study, we observed an increase in the severity of acute pancreatitis with prolonged fasting in a severe acute pancreatitis model. These results suggest that in clinical practice, the preoperative fasting time should be shortened before pancreatic procedures.

Molecular Characterization of Enteric Viruses Causing Acute Gastroenteritis among Children under 5 Years Old in Distrito Central, Honduras.

INTRODUCTION: Diarrheal diseases constitute a significant public health problem in terms of mortality and morbidity. In Honduras and around the world, RVs have consistently emerged as the single most important etiologic agent in acute childhood diarrhea. However, other viruses, such as NoVs and HAstVs, have also been shown to be responsible for viral gastroenteritis. Unfortunately, the country has limited information concerning the etiologic role of these viral agents in acute gastroenteritis. This study investigated the frequency, genotypes, and epidemiological characteristics of RV-A, NoVs, and HAstVs among children under 5 years old in Distrito Central, Honduras. METHODS: Stool samples and their corresponding epidemiological data were collected from children with acute gastroenteritis in three healthcare centers in Distrito Central. All samples were screened by immunoassays for RV-A and HAstVs. RV-A-positive samples were molecularly characterized by RT-PCR and genotyping assays. RT-PCR was also applied to confirm HAstVs positivity and to detect NoVs, followed by nucleotide sequencing to assign their genotypes. RESULTS: Our results show that at least one viral agent was detected in 31% of the children. The frequency of RV-A, NoVs, and HAstVs was 14%, 13%, and 5%, respectively. The most frequent RV-A genotype was G2P[4], occurring in 93% of cases. 92.3% of NoVs-positive samples belonged to genogroup II, with GII.4 and GII.16 being the most common. HAstVs were clustered into three genotypes: HAstV-1, HAstV-2, and HAstV-8. Only one sample showed coinfection with NoVs and HAstVs. CONCLUSION: This comprehensive molecular and epidemiological characterization of enteric viruses demonstrates the vast diversity of these agents and describes for the first time NoVs and HAstVs as causative agents of acute childhood gastroenteritis in Distrito Central, Honduras. This suggests that further in-depth studies of the pediatric population are necessary to develop and implement effective preventive and control measures in the country.

Acetazolamide therapy in patients with acute heart failure: a systematic review and meta-analysis of randomized controlled trials.

Acute heart failure (AHF) often leads to unfavorable outcomes due to fluid overload. While diuretics are the cornerstone treatment, acetazolamide may enhance diuretic efficiency by reducing sodium reabsorption. We performed a systematic review and meta-analysis on the effects of acetazolamide as an add-on therapy in patients with AHF compared to diuretic therapy. PubMed, Embase, and Cochrane databases were searched for randomized controlled trials (RCT). A random-effects model was employed to compute mean differences and risk ratios. Statistical analysis was performed using R software. The GRADE approach was used to rate the certainty of the evidence. We included 4 RCTs with 634 patients aged 68 to 81 years. Over a mean follow-up of 3 days to 34 months, acetazolamide significantly increased diuresis (MD 899.2 mL; 95% CI 249.5 to 1549; p < 0.01) and natriuresis (MD 72.44 mmol/L; 95% CI 39.4 to 105.4; p < 0.01) after 48 h of its administration. No association was found between acetazolamide use and WRF (RR 2.4; 95% CI 0.4 to 14.2; p = 0.3) or all-cause mortality (RR 1.2; 95% CI 0.8 to 1.9; p = 0.3). Clinical decongestion was significantly higher in the intervention group (RR 1.35; 95% CI 1.09 to 1.68; p = 0.01). Acetazolamide is an effective add-on therapy in patients with AHF, increasing diuresis, natriuresis, and clinical decongestion, but it was not associated with differences in mortality.

Role of green banana consumption in the treatment of acute and persistent diarrhea in children: a systematic review and meta-analysis of randomized controlled trials.

Green banana Musa paradisiaca (GB) has been traditionally used to aid in the treatment of diarrhea. This systematic review and meta-analysis aimed to evaluate current evidence of the effect of GB consumption as a complement to standard treatment in the population with acute or persistent diarrhea. We searched PubMed, Scopus, Web of Science, and LILACS from inception to January 2024; there was no language restriction. Only randomized controlled trials using GB as an intervention were included, and studies using antidiarrheal medication were excluded. A meta-analysis was performed to compare the effect of GB on the resolution of acute and persistent diarrhea. To measure the certainty of evidence, the GRADE assessment was used. Nine randomized controlled trials (seven open and two blinded) were included. Studies were conducted in the pediatric population comprising a total of 3996 patients aged 8 to 34 months, eight studies were written in English and one in Spanish. GB-based food consumption significantly increased the hazard of resolution of diarrhea compared to standard treatment (HR 1.96, 95% CI [1.62; 2.37], p < 0.01; I2 = 52%). The subgroup analysis showed a higher hazard of resolution of diarrhea for children with persistent diarrhea (HR 2.34, 95% CI [1.78; 3.08] compared to acute diarrhea (HR 1.74, 95% CI [1.45; 2.09]).Conclusions: The use of green banana-based foods as a complement to standard treatment in children is probably associated with a faster resolution in acute diarrhea and may aid in the treatment of persistent diarrhea. More clinical trials are necessary to assess if a synergistic effect between GB and other foods exists and proves to be better than GB alone. These findings need to be confirmed in diverse socioeconomic contexts, within the adult population, and under varying health conditionsTrial registration: CRD42024499992.

HIV acute infection and long-term undisclosed HIV status among blood donors from the highly endemic Amazonas state, located in the Brazilian Amazon.

BACKGROUND: The Amazonas state/AM and Manaus rank among the highest AIDS detection rates in Brazil. High proportion of HIV infected blood donors and transmission clusters of multidrug antiretroviral/ARV resistant viruses were described in HEMOAM blood donors, a main Amazonas public blood bank. Recent and long-term infections among previously genotyped donors are reported. METHODS/MATERIALS: The recency immunoassay Lag Avidity EIA (Maxim, USA) was employed. Clinical/CD4/viral load medical file data of the main local HIV management center (FMT-HVD) and ARV treatment/ART data were reviewed. RESULTS: Among 142 HIV-blood donors, chronic infection predominated (n = 87; 61.3 %), 79 based on LAg EIA and 8 undisclosed HIV identified in FMT-HVD records, mostly young adult, single males, 4 repeat donors, all ART-naive. Recent infections represented 30.3 % (n = 43), 39 identified by LAg EIA and 4 immunologic windows (antibody negative/NAT/RNA positive). The overall profile of recent and long-term infections was similar, including moderate rate of transmitted drug resistance/TDR, however with multiple resistance mutations to more than one ARV-class, suggesting ART/failure. DISCUSSION: Recent/acute and undisclosed/long-term HIV infections represent blood safety alerts suggesting test-seeking behavior of at-risk populations. Early ART use in Brazil, can turn HIV diagnosis more challenging representing a blood transfusion risk in the highly endemic Brazilian Amazon.

Evaluation of different cut-off points for IgG avidity and IgM in the diagnosis of acute toxoplasmosis in pregnant women participating in a congenital toxoplasmosis screening program.

The main social impact of toxoplasmosis stems from its ability to be vertically transmitted. Postnatally acquired infection is generally asymptomatic in approximately 70-90% of cases, making diagnosis often dependent on laboratory tests using serological methods to search for anti-T. gondii antibodies. This study aimed to investigate the ability of the VIDAS TOXO IgG avidity and VIDAS TOXO IgM assays to confirm recent toxoplasmosis. In total, 341 pregnant women with suspected acute toxoplasmosis were systematically monitored in the Program for Control of Congenital Toxoplasmosis in Minas Gerais State, Brazil. We conducted an observational analytical-descriptive cross-sectional study and grouped according to clinical and laboratory criteria as having acute or chronic toxoplasmosis. The VIDAS TOXO IgG avidity and VIDAS TOXO IgM assays were evaluated to investigate the capacity to identify acute infection. IgG avidity showed good performance in identifying acute toxoplasmosis when the IgG avidity index was lower than or equal to 0.1. Values greater than or equal to 3.16 according to the TOXO IgM kit were associated with a greater chance of acute infection. These results may contribute to a more adequate diagnosis of acute gestational toxoplasmosis and, consequently, the avoidance of inadequate or unnecessary treatments.

Seasonality of the incidence of bronchiolitis in infants - Brazil, 2016-2022: An interrupted time-series analysis.

OBJECTIVE: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020-2022 season and compare it with the previous seasons. METHODS: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. RESULTS: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 - August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 - December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020-2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. CONCLUSIONS: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

The Effect of Early Administration of Hypertonic Saline Solution In Acute Decompensated Heart Failure. / O Efeito da Administração Precoce de Solução Salina Hipertônica na Insuficiência Cardíaca Descompensada Aguda.

BACKGROUND: There was no scientific evidence about the initial treatment of hypertonic saline solution (HSS) in acutely decompensated heart failure (ADHF). OBJECTIVES: This study assessed the impact of using HSS along with a loop diuretic (LD) as the first diuretic treatment for ADHF, focusing on renal function, electrolyte levels, and clinical outcomes. METHODS: In this retrospective case-control study, 171 adult patients (93 females/78 males) with ADHF were included between January 1, 2022, and December 31, 2022. Patients were allocated into two groups: upfront combo HSS+LD and standardized LD. The primary endpoint was worsening renal function (WRF). Hospitalization for HF and all-cause mortality were evaluated during 6 months of follow-up. The significance level adopted in the statistical analysis was 5%. RESULTS: The groups exhibited similarities in baseline characteristics.A significantly higher diuresis on the 1st day (3975 [3000-5150] vs. 2583 [2000-3250], p=0.001) and natriuresis on the 2nd hour (116.00 [82.75-126.00] vs. 68.50 [54.00-89.75], p=0.001) in the initial upfront combo HSS+LD were found in comparison with the standardized LD.When compared to the standardized LD, the utilization of HSS led to an increase in serum Na+ (137.00 [131.75-140.00] vs. 140.00 [136.00-142.25], p=0.001 for upfront combo HSS, 139.00 [137.00-141.00] vs. 139.00 [136.00-140.00], p=.0470 for standardized LD), while chloride (99.00 [94.00-103.25] vs. 99.00[96.00-103.00], p=0.295), GFR (48.50 [29.75-72.50 vs. 50.00 [35.50-63.50, p=0.616), and creatinine (1.20 [0.90-1.70] vs. 1.20 [1.00-1.50], p=0.218) remained stable in the upfront combo HSS group when compared to standardized LD group (Cl-: 102.00 [99.00-106.00] vs. 98.00 [95.00-103.00], p=0.001, eGFR: 56.00 [41.00-71.00] vs. 55.00 [35.00-71.00], p=0.050, creatinine:1.10 [0.90-1.40] vs. 1.20 [0.90-1.70], p=0.009). Worsening renal function (16.1% vs 35.5%, p=0.007), and length of stay in the hospital (4 days [3-7] vs. 5 days [4-7], p=0.004) were lower in the upfront combo HSS+LD in comparison with the standardized LD. In-hospital mortality, hospitalization for HF, and all-cause mortality were similar between the two groups. CONCLUSION: HSS as an initial therapy, when combined with LD, may provide a safe and effective diuresis without impairing renal function in ADHF. Therefore, HSS may lead to a shorter length of stay in the hospital for these patients.

FUNDAMENTO: Não houve evidência científica sobre o tratamento inicial com solução salina hipertônica (SSH) na insuficiência cardíaca agudamente descompensada (ICAD). OBJETIVOS: Este estudo avaliou o impacto do uso de SSH junto com um diurético de alça (DA) como o primeiro tratamento diurético para ICAD, com foco na função renal, níveis de eletrólitos e resultados clínicos. MÉTODOS: Neste estudo retrospectivo de caso-controle, 171 pacientes adultos (93 mulheres/78 homens) com ICAD foram incluídos entre 1º de janeiro de 2022 e 31 de dezembro de 2022. Os pacientes foram alocados em dois grupos: combinação inicial de SSH+DA e DA padronizada. O desfecho primário foi piora da função renal (PFR). A hospitalização por IC e a mortalidade por todas as causas foram avaliadas durante 6 meses de acompanhamento. O nível de significância adotado na análise estatística foi de 5%. RESULTADOS: Os grupos exibiram semelhanças nas características basais. Diurese significativamente maior no 1º dia (3975 [3000-5150] vs. 2583 [2000-3250], p=0,001) e natriurese na 2ª hora (116,00 [82,75-126,00] vs. 131,75-140,00] vs. 94,00-103,25] vs. 99,00 [96,00-103,00], p=0,295), TFG (48,50 [29,75-72,50 vs. 50,00[35,50-63,50, p=0,616) e creatinina (1,20 [0,90-1,70] vs. 1,20 [1,00-1,50], p=0,218) permaneceu estável no grupo SSH combinado inicial quando comparado ao grupo DA padronizado (Cl-: 102,00[99,00-106,00] vs. 98,00[95,00-103,00], p=0,001, TFGe: 56,00 [41,00-71,00] vs. 55,00[35,00-71,00], p=0,050, creatinina: 1,10[0,90-1,40] vs. 1,20 [0,90-1,70], p=0,009). A piora da função renal (16,1% vs. 35,5%, p = 0,007) e o tempo de internação hospitalar (4 dias [3-7] vs. 5 dias [4-7], p = 0,004) foram menores na combinação inicial SSH+DA em comparação com o DA padronizado. A mortalidade hospitalar, a hospitalização por IC e a mortalidade por todas as causas foram semelhantes entre os dois grupos. CONCLUSÃO: SSH como terapia inicial, quando combinada com DA, pode proporcionar uma diurese segura e eficaz sem prejudicar a função renal na ICAD. Portanto, a SSH pode levar a um menor tempo de internação hospitalar para esses pacientes.

Association of Pan Immune-Inflammation Value with Long Term Outcomes of Acute Decompensated Heart Failure. / Associação do Valor Pan-Imune-Inflamatório com Desfechos de Longo Prazo na Insuficiência Cardíaca Agudamente Descompensada.

BACKGROUND: Although there have been significant improvements in the treatment of heart failure (HF) in recent decades, its prognosis remains poor. Although there are many biomarkers that can help predict the prognosis of patients with HF, there is a need for simpler, cheaper, and more easily available biomarkers. OBJECTIVE: To evaluate the predictive value of pan-immune-inflammation value (PIV) in patients with acute decompensated HF. METHODS: We analyzed 409 patients with HF with reduced ejection fraction who were hospitalized for acute decompensated HF. Patients were divided into 3 groups according to tertiles of PIV: tertile 1 (PIV < 357.25), tertile 2 (PIV ≥ 357.25 and < 834.55), and tertile 3 (PIV ≥ 834.55). P values < 0.05 were considered statistically significant. Kaplan-Meier curves and Cox proportional hazards regression models were used to evaluate the association between PIV and all-cause mortality. The primary outcome was 5-year all-cause mortality, and the secondary outcomes were in-hospital 30 days,, 180-day, and 1-year all-cause mortality. RESULTS: We showed that higher PIV value was associated with both primary and secondary outcomes. The Kaplan-Meier curve showed that patients with higher PIV values had an increased risk of short- and long-term all-cause mortality (log-rank p < 0.001). In the multivariate analysis, PIV was identified as an independent predictor of long-term all-cause mortality in patients with acute decompensated HF, and we observed a 1.96-fold increase in the hazard of an event (odds ratio: 1.96, 95% confidence interval: 1.330 to 2.908, p = 0.001). CONCLUSIONS: Our study showed that the novel biomarker PIV can be used as a predictor of prognosis in patients with acute decompensated HF.

FUNDAMENTO: Embora tenha havido melhorias significativas no tratamento da insuficiência cardíaca (IC) nas últimas décadas, seu prognóstico permanece desfavorável. Embora existam muitos biomarcadores que podem ajudar a prever o prognóstico de pacientes com IC, há necessidade de biomarcadores mais simples, menos dispendiosos e mais facilmente disponíveis. OBJETIVO: Avaliar o valor preditivo do valor pan-imune-inflamatório (PIV, do inglês pan-immune-inflammation value) em pacientes com IC agudamente descompensada. MÉTODOS: Analisamos 409 pacientes com IC com fração de ejeção reduzida internados por IC aguda descompensada. Os pacientes foram divididos em 3 grupos de acordo com os tercis de PIV: tercil 1 (PIV < 357,25), tercil 2 (PIV ≥ 357,25 e < 834,55) e tercil 3 (PIV ≥ 834,55). Foram considerados estatisticamente significativos valores de p < 0,05. Curvas de Kaplan-Meier e modelos de regressão de riscos proporcionais de Cox foram utilizados para avaliar a associação entre PIV e mortalidade por todas as causas. O desfecho primário foi mortalidade por todas as causas em 5 anos, e o desfecho secundário compreendeu a mortalidade por todas as causas intra-hospitalar em 30 dias, em 180 dias e em 1 ano. RESULTADOS: Mostramos que valores mais elevados de PIV estavam associados a desfechos primários e secundários. A curva de Kaplan-Meier mostrou que pacientes com valores mais elevados de PIV apresentaram risco aumentado de mortalidade por todas as causas em curto e longo prazo (log-rank p < 0,001). Na análise multivariada, o PIV foi identificado como um preditor independente de mortalidade por todas as causas em longo prazo em pacientes com IC aguda descompensada, e observamos um aumento de 1,96 vezes no risco de um evento (razão de chances: 1,96; intervalo de confiança de 95%: 1,330 a 2,908; p = 0,001). CONCLUSÕES: Nosso estudo mostrou que o novo biomarcador PIV pode ser usado como preditor de prognóstico em pacientes com IC aguda descompensada.
