RESUMO

BACKGROUND: Ischemic cardiomyopathy (ICM) accounts for more than 60% of congestive heart failure cases and is associated with high morbidity and mortality rates. Myocardial revascularization in patients with left ventricular dysfunction (LVD) and a left ventricular ejection fraction (LVEF) ≤35% aims to improve survival and quality of life and reduce complications associated with heart failure and coronary artery disease. The majority of randomized clinical trials have consistently excluded those patients, resulting in evidence primarily derived from observational studies. MAIN BODY: We performed a scoping review using the Arksey and O'Malley methodology in five stages: 1) formulating the research question; 2) locating relevant studies; 3) choosing studies; 4) organizing and extracting data; and 5) compiling, summarizing, and presenting the findings. This literature review covers primary studies and systematic reviews focusing on surgical revascularization strategies in adult patients with ischemic left ventricular dysfunction (LVD) and a left ventricular ejection fraction (LVEF) of 35% or lower. Through an extensive search of Medline and the Cochrane Library, a systematic review was conducted to address three questions regarding myocardial revascularization in these patients. These questions outline the current knowledge on this topic, current surgical strategies (off-pump vs. on-pump), and graft options (including hybrid techniques) utilized for revascularization. Three independent reviewers (MAE, DP, and AM) applied the inclusion criteria to all the included studies, obtaining the full texts of the most relevant studies. The reviewers subsequently assessed these articles to make the final decision on their inclusion in the review. Out of the initial 385 references, 156 were chosen for a detailed review. After examining the full articles were examined, 134 were found suitable for scoping review. CONCLUSION: The literature notes the scarcity of surgical revascularization in LVD patients in randomized studies, with observational data supporting coronary revascularization's benefits. ONCABG is recommended for multivessel disease in LVD with LVEF < 35%, while OPCAB is proposed for older, high-risk patients. Strategies like internal thoracic artery skeletonization harvesting and postoperative glycemic control mitigate risks with BITA in uncontrolled diabetes. Total arterial revascularization maximizes long-term survival, and hybrid revascularization offers advantages like shorter hospital stays and reduced costs for significant LAD lesions.

RESUMO

La dismenorrea es una afección menstrual común en mujeres de edad reproductiva, caracterizada por dolor pélvico durante el ciclo menstrual. En este artículo, se revisan los factores de riesgo, la clínica y el diagnóstico de la dismenorrea primaria con el objetivo de proponer un enfoque de tratamiento multimodal para esta condición. La dismenorrea primaria es el dolor pélvico asociado al período menstrual sin una patología pélvica subyacente. La dismenorrea secundaria es el dolor pélvico que se presenta como síntoma de otras afecciones ginecológicas. El diagnóstico se basa en la historia clínica, la exploración física y ginecológica, y se pueden realizar pruebas complementarias en casos específicos. El tratamiento de la dismenorrea primaria es multimodal y tiene como objetivo aliviar el dolor y mejorar la calidad de vida de las pacientes. Los fármacos antiinflamatorios no esteroideos son la primera línea de tratamiento, aunque se pueden utilizar otros enfoques terapéuticos(AU)

Dysmenorrhea is a common menstrual condition in women of reproductive age, characterized by pelvic pain during the menstrual cycle. This article reviews the risk factors, clinic and diagnosis of primary dysmenorrhea to propose a multimodal treatment approach for this condition. Primary dysmenorrhea is pelvic pain associated with the menstrual period without underlying pelvic pathology. In contrast, secondary dysmenorrhea refers to pelvic pain that presents as a symptom of other gynecologic conditions. Diagnosis is based on detailed clinical history, physical and gynecological examination, and complementary tests may be performed in specific cases. Treatment of primary dysmenorrhea is multimodal and aims to relieve pain and improve the patient's quality of life. Nonsteroidal anti-inflammatory drugs are the first line of treatment, although other therapeutic approaches can be employed(AU)

RESUMO

INTRODUCTION: Osteoarthritis is a disabling pathology characterized by joint pain and stiffness. A prevalence of coxarthrosis of 7.4% is reported in our country. Total hip joint replacement is indicated in advanced stages, a procedure that is not free of complications, the most frequent being prosthetic dislocation, which can be prevented with dual mobility systems. The following study aims to determine the rate of complications and clinical outcomes in dual mobility systems in primary coxarthrosis. MATERIALS AND METHODS: A retrospective study included 120 cases in 114 patients diagnosed with grade III coxarthrosis, mean age was 62.43 years, with a mean follow-up of 4.5 years. Joint replacement was performed by Hardinge approach. All cases were assessed clinically using the Harris Hip Score (HHS) and radiologically to demonstrate mid-term results. RESULTS: The preoperative value on the HHS scale had a mean of 56.45, postoperative at one month 74.23; 6 months 85.40; 1 year 94.01 and at 5 years 94.84 points, representing a functional improvement of 17.78 postoperative month; 28.95 at 6 months postoperative; 37.56 at one year postoperative and 38.39 points at 5 years postoperative. A complication rate of 3.44%; 0.86% of complications were associated with the prosthetic components. CONCLUSION: The dual mobility system should be considered as a therapeutic option in primary hip joint replacement due to excellent functional results and low complication rates. EVIDENCE LEVEL: IV. Retrospective observational case series study.

RESUMO

The current study used the McGill Illness Narrative Interview (MINI) to explore patients' (n = 6) and caregivers' (n = 3) narratives about how they identified and sought care for psychosis. Participants were recruited from an outpatient clinic at the Hospital Psiquiátrico Dr. Rafael Serrano, a public psychiatric hospital in Puebla, Mexico. All participants consented to complete semi-structured interviews in Spanish. Thematic analyses were used to inductively identify common themes in participants' narratives. The results indicated that during the initial symptom onset, most participants noticed the presence of hallucinations but did not seek help for this hallmark symptom. Participants described seeking care only when they or their ill relative exhibited escalating aggressive behaviors or physical symptoms that were interpreted as common medical problems. As participants became connected to specialty mental health services, they began to develop a conceptualization of psychosis as a disorder of aggression. For some participants, this conceptualization of psychosis as an illness of aggression contributed to their ambivalence about the diagnosis. These results can be understood using a cultural scripts framework, which suggests that cultural norms are influenced by collective understandings of normalcy and valorization of behaviors. Implications for community campaigns are discussed.

RESUMO

BACKGROUND: Information on the performance of oxygenation indices (OIs) and risk scores in patients requiring invasive mechanical ventilation (IMV) is limited. We determine the performance of the OIs and risk scores in hospitalized patients with COVID-19 to predict the requirement of IMV and death at 28 days after admission. METHODS: A retrospective study of diagnostic tests in patients admitted to the emergency department, hospitalization, and intensive care unit diagnosed with COVID-19. The receiver operating characteristic curve (ROC-curve) were built with the OIs and risk scores to predict IMV and mortality. RESULTS: A total of 1402 subjects entered the final analysis, of whom 19.5% (274/1402) received IMV and 23.0% (323/1402) died at 28 days. The ROC-curve of the delta PaO2/FiO2 ratio for the requirement of IMV and mortality at 28-day was 0.589 (95% CI: 0.546-0.632) and 0.567 (95% CI: 0.526-0.608), respectively. PaO2/FiO2 ≤ 300 shows a ROC curve of 0.669 (95% CI: 0.628-0.711) to predict IMV. PaO2/FiO2 ≤ 300 and 4 C mortality score in mortality at 28 days showed an ROC-curve of 0.624 (95% CI: 0.582-0.667) and 0.706 (95% CI: 0.669-0.742), respectively. CONCLUSION: PaO2/FiO2 ≤ 300, 4 C mortality score ≥ 8, SOFA score ≥ 4 y SaO2/FiO2 ≤ 300 were weak predictors of the IMV requirement from admission, and 4 C mortality score ≥ 8 was weak predictors of the mortality from admission in patients with pulmonary involvement by COVID-19.

RESUMO

OBJECTIVES: Determine the geographic place of origin and maternal lineage of prehistoric human skeletal remains discovered in Puyil Cave, Tabasco State, Mexico, located in a region currently populated by Olmec, Zoque and Maya populations. MATERIALS AND METHODS: All specimens were radiocarbon (14C) dated (beta analytic), had dental modifications classified, and had an analysis of 13 homologous reference points conducted to evaluate artificial cranial deformation (ACD). Following DNA purification, hypervariable region I (HVR-1) of the mitogenome was amplified and Sanger sequenced. Finally, Next Generation Sequencing (NGS) was performed for total DNA. Mitochondrial DNA (mtDNA) variants and haplogroups were determined using BioEdit 7.2 and IGV software and confirmed with MITOMASTER and WebHome softwares. RESULTS: Radiocarbon dating (14C) demonstrated that the inhabitants of Puyil Cave lived during the Archaic and Classic Periods and displayed tabular oblique and tabular mimetic ACD. These pre-Hispanic remains exhibited five mtDNA lineages: A, A2, C1, C1c and D4. Network analysis revealed a close genetic affinity between pre-Hispanic Puyil Cave inhabitants and contemporary Maya subpopulations from Mexico and Guatemala, as well as individuals from Bolivia, Brazil, the Dominican Republic, and China. CONCLUSIONS: Our results elucidate the dispersal of pre-Hispanic Olmec and Maya ancestors and suggest that ACD practices are closely related to Olmec and Maya practices. Additionally, we conclude that ACD has likely been practiced in the region since the Middle-Archaic Period.

RESUMO

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical trial updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.Two years of adjuvant abemaciclib combined with endocrine therapy (ET) resulted in a significant improvement in invasive disease-free survival (IDFS) and distant relapse-free survival (DRFS) that persisted beyond the 2-year treatment period in patients with hormone receptor-positive, human epidermal growth factor receptor 2-negative, node-positive, high-risk early breast cancer (EBC). Here, we report 5-year efficacy results from a prespecified overall survival (OS) interim analysis. In the intent-to-treat population, with a median follow-up of 54 months, the benefit of abemaciclib was sustained with hazard ratios of 0.680 (95% CI, 0.599 to 0.772) for IDFS and 0.675 (95% CI, 0.588 to 0.774) for DRFS. This persistence of abemaciclib benefit translated to continuous separation of the curves with a deepening in 5-year absolute improvement in IDFS and DRFS rates of 7.6% and 6.7%, respectively, compared with rates of 6% and 5.3% at 4 years and 4.8% and 4.1% at 3 years. With fewer deaths in the abemaciclib plus ET arm compared with the ET-alone arm (208 v 234), statistical significance was not reached for OS. No new safety signals were observed. In conclusion, abemaciclib plus ET continued to reduce the risk of developing invasive and distant disease recurrence beyond the completion of treatment. The increasing absolute improvement at 5 years is consistent with a carryover effect and further supports the use of abemaciclib in patients with high-risk EBC.

RESUMO

Abstract Background: Arterial hypertension (AH) is a chronic disease distributed worldwide, and the Angiotensin II receptor type 2 (AGTR2) gene variants are potential DNA markers to study in association with this disease. Objective: This systematic review (SR) aimed to identify single nucleotide variants in the AGTR2 gene as genetic markers associated with AH. Methods: The electronic databases MEDLINE, Web of Science, SCOPUS, Cochrane Central Register, EMBASE, SciELO, and TripDatabase were searched for research up to September 2023. Case-control studies with DNA variants in the AGTR2 gene associated with AH as the outcome were included in the review. Boolean connectors and keywords were used according to each database. Results: After diverse rounds of scrutiny, a final number of eight articles were included for 8911 participants, comprising 5451 cases and 3460 controls. A significant proportion of the selected studies were performed in Asian populations and were heterogeneous. Although 238 variants were shown in the gnomAD v2.1.1 database for September 2023, only six variants were identified in all the analyzed studies. Conclusions: The results obtained were not conclusive that a specific variant located in the AGTR2 gene has a strong association with AH. The study of this gene re-emerged last year as an essential target to investigate due to its participation in the development of agonist therapy to treat mild COVID-19 cases. Future studies with better statistical power are desirable to replicate the primary findings.

RESUMO

Resumen Las dificultades de aprendizaje, que pueden continuar manifestándose en la adultez, han mostrado vinculación con déficit en el procesamiento sensorial. El propósito de la investigación es indagar el perfil sensorial de adultos con y sin dificultades de aprendizaje (DA) en el área de lectoescritura. El estudio es cuantitativo no experimental. El perfil sensorial se evaluó a través de un cuestionario basado en el modelo de Dunn (1997b), que define cuatro patrones sensoriales a partir de la interacción entre el umbral neurológico y las estrategias de autorregulación, junto a un autorreporte de dificultades de aprendizaje. Los resultados mostraron puntuaciones similares en tres patrones sensoriales para ambos grupos, con diferencias significativas en el patrón sensorial de 'Espectador' (p = .038, d =0.5). Este patrón caracterizaría a adultos con DA con una tendencia a estrategias de autorregulación pasiva y umbral neurológico alto. Se concluye que las características de procesamiento sensorial pueden ser relevantes para orientar la intervención y apoyo de personas con DA. Se demuestra la relevancia de analizar el perfil de procesamiento sensorial para la comprensión de las dificultades de aprendizaje. En términos aplicados, amplía las posibilidades de apoyo para adultos con DA al visibilizar la necesidad de entornos que respondan a las características sensoriales individuales.

Abstract Learning difficulties, which may continue to manifest into adulthood, are linked to deficits in sensory processing. A study focused on investigating the sensory profile of adults with and without learning difficulties (LD) in literacy is presented. Quantitative and non-experimental study. The sensory profile was assessed through a questionnaire based on Dunn's model (1997b), which defines four sensory patterns based on the interaction between the neurological threshold and self-regulation strategies. We also included a self-reporting of LD. The results showed similar scores in three sensory patterns for both groups, with significant differences in the 'Bystander' sensory pattern (p = .038, d = 0.5). This pattern would characterize adults with LD with a tendency for passive self-regulation strategies and a high neurological threshold. Sensory processing characteristics may be relevant to guide the intervention and support of people with LD. Our findings demonstrate the relevance of analyzing the sensory processing profile for understanding learning difficulties. In applied terms, it expands support possibilities for adults with LD by highlighting the need for environments that respond to individual sensory characteristics.

RESUMO

Intestinal parasites continue to be a public health problem in low- and middle-income countries. Broad use of anthelmintics during deworming programs is still necessary in many regions. However, description of the usage of these medications in general medical practice has been limited. The objective of this study was to determine the use of anthelmintic drugs and their indications in a group of Colombian patients. This was a descriptive study from a drug-dispensing database, identifying patients with prescriptions for anthelmintic drugs. A total of 381 cases were randomly selected, and their medical records were reviewed, analyzing sociodemographic, clinical, and pharmacological variables (indication of use). The lack of diagnosis registration or clinical manifestations of parasites was determined as a prescription without indication. In total, 50.9% (n = 194) of patients were female, and 67.4% of all patients were under 18 yr of age. The diagnosis of helminthiases was clearly stated in 114 (29.9%) patients, and only 4.2% (n = 16) of these had microbiological confirmation. The most commonly used anthelmintic drug was albendazole (70.4% of all prescriptions). The use of anthelmintics was not indicated in 266 cases (69.8%). Nutritional supplements or vitamin prescriptions were associated with using anthelmintics without indication (odds ratio: 2.25; 95% confidence interval: 1.26-4.03). A high proportion of patients lacked symptoms or diagnoses in their clinical records that supported the use of anthelmintic drugs.
