Complementary and Alternative Medicine (CAM) Practices: A Narrative Review Elucidating the Impact on Healthcare Systems, Mechanisms and Paediatric Applications.

While research on complementary and alternative medicine (CAM) for the general population is expanding, there remains a scarcity of studies investigating the efficacy and utilisation of CAM practices, specifically in the paediatric population. In accordance with the World Health Organization (WHO), the prevalence of the parental utilisation of CAM in their dependents is estimated to reach up to 80%. This literature review identified broad, heterogeneous, and inconclusive evidence regarding CAM's applications and effectiveness, primarily attributed to variance in sociodemographic factors and differences in national healthcare systems. Additionally, the review identified a lack of consensus and polarised positions among mainstream professionals regarding the mechanisms of action, applications, and effectiveness of CAM. This narrative review presents varied results concerning the efficacy of most CAM therapies and their applications; however, some evidence suggests potential benefits for acupuncture, yoga, tai chi, and massage in improving physical and mental health. Moreover, the available evidence indicates that meditation may enhance mental health, while reiki may only influence patients' perceptions of comfort. In light of the intricate and multifaceted nature of herbal medicine, it is imperative to assess its efficacy on a case-by-case basis, taking into account the specific compounds and procedures involved. This comprehensive review serves as a valuable resource for health professionals, offering guidance for personalised healthcare approaches that consider the values and beliefs of patients, thereby facilitating integrated, evidence-based practices aimed at enhancing the quality of healthcare services and patient satisfaction.

A Look at Plant-Growth-Promoting Bacteria.

Bacteria have been used to increase crop yields. For their application on crops, bacteria are provided in inoculant formulations that are continuously changing, with liquid- and solid-based products. Bacteria for inoculants are mainly selected from natural isolates. In nature, microorganisms that favor plants exhibit various strategies to succeed and prevail in the rhizosphere, such as biological nitrogen fixation, phosphorus solubilization, and siderophore production. On the other hand, plants have strategies to maintain beneficial microorganisms, such as the exudation of chemoattractanst for specific microorganisms and signaling pathways that regulate plant-bacteria interactions. Transcriptomic approaches are helpful in attempting to elucidate plant-microorganism interactions. Here, we present a review of these issues.

Cardiac computed tomography assessment of congenital aortic diseases: a case series.

Background: Congenital aortic diseases (CAoD) encompass a wide variety of disorders that range from asymptomatic findings to life-threatening conditions. Multiple imaging techniques are available for the assessment of CAoD. Case summary: We present seven case reports of congenital aortic diseases, including obstructions in the aortic arch (coarctation, hypoplasia, and interruption) and vascular rings, in which the clinical manifestations throughout the cases are discussed, highlighting the heterogeneity of the symptoms. Discussion: Multi-imaging techniques are indispensable for the assessment of CAoD, where cardiac computed tomography angiography is the main modality for rapid acquisition of three-dimensional volume-rendered images for optimal surgical planning.

Coronary Artery Disease in Women: Getting to Know Gender Related Disparities

Abstract Coronary artery disease (CAD) and ischemic heart disease (IHD) are often indistinctly used terms. Both combined have generated, over the past years, concerns about sex disparities in their presentation. From an epidemiological perspective, females have several disadvantages regarding the prevention, diagnosis, and treatment of CAD. Most of the general cardiovascular risk factors affect women more frequently, or with a higher morbidity and mortality association. Besides, atypical manifestations of the disease and uncommon forms of CAD represent a diagnostic challenge for clinicians. Even if current treatments for CAD have no apparent sex bias, women representation in clinical trials and treatment patterns analyzed in clinical practice refuse this statement. Several disparities are caused by inevitable sex-particularities, but many of them are more social, cultural, and dogmatic beliefs that have to be addressed and overhaul.

Immune checkpoint inhibitors-associated thrombosis in patients with lung cancer and melanoma: a study of the Spanish society of medical oncology (SEOM) thrombosis and cancer group.

PURPOSE: Immune Checkpoint Inhibitors (ICI) can be associated with thrombotic events, both venous and arterial (VTE/AT). However, there is a paucity of information regarding patients in routine clinical practice. METHODS/PATIENTS: Retrospective, multicenter study promoted by the Thrombosis and Cancer Section of the Spanish Society of Medical Oncology (SEOM). Patients with melanoma and lung cancer who initiated ICI between 01/01/2015 and 31/12/2019 were recruited. Minimum follow-up was 6 months (unless it was not possible because of death). The primary objective was to calculate the incidence of ICI-associated VTE/AT and the secondary objectives included to analyze its impact on survival and to identify predictor variables for VTE/AT. RESULTS: 665 patients with lung cancer were enrolled. The incidence of VTE/AT during follow-up was 8.4%. Median overall survival (OS) was lower in the VTE/AT group (12 months 95% CI 4.84-19.16 vs. 19 months 95% CI 16.11-21.9; p = 0.0049). Neutrophil/lymphocyte ratio (NLR) and anemia upon initiation of IT, as well as a history of thrombosis between cancer diagnosis and the start of ICI, were predictive variables for developing of VTE/AT (p < 0.05). 291 patients with melanoma were enrolled. There was a 5.8% incidence rate of VTE/AT during follow-up. Median OS was lower in the VTE/AT group (10 months 95% CI 0.0-20.27 vs. 29 months 95% CI 19.58-36.42; p = 0.034). NLR and lactate dehydrogenase (LDH) at the beginning of ICI were predictor variables for VTE/AT (p < 0.05). CONCLUSIONS: ICI increases the risk of VTE/AT in patients with lung cancer and melanoma, which impact OS.

Role of the Antioxidant Activity of Melatonin in Myocardial Ischemia-Reperfusion Injury.

Ischemia-reperfusion injury is a common problem in the age of interventional cardiology; it is primarily mediated by oxidative stress and reactive agents. Melatonin has antioxidative properties that make its use promising for treating ischemia-reperfusion injury. Multiple experimental studies in murine and porcine models have been performed with good results. Clinical trials have also been conducted but given their heterogeneity, no conclusive results can be made. Melatonin pharmacokinetic properties are not ideal; therefore, many analogs have been proposed with improved characteristics, and some studies have evaluated their efficacy in animal models, but clinical trials are needed to recommend their use. In this review, we expose the results of the most impactful studies regarding melatonin use in ischemia-reperfusion injury.

Right Heart Chambers Longitudinal Strain Provides Enhanced Diagnosis and Categorization in Patients With Pulmonary Hypertension.

Background: Increased systolic pulmonary arterial pressure (sPAP) could lead to the mechanical dysfunction and myocardial fibrosis of the right heart chambers. Echocardiographic strain analysis has not been adequately studied in patients with pulmonary hypertension (PH). Study design and methods: A cross-sectional cohort of patients with suspected PH and echocardiographic strain evaluation was recruited. The cut-off values of peak tricuspid regurgitation velocity (TRV) with the low probability of PH (≤2.8 m/s), intermediate probability (2.9-3.4 m/s, without other echo PH signs), and high probability of PH (2.9-3.4 m/s with other echo PH signs and >3.4 m/s) categories were studied by right ventricular and right atrial (RA) strain analysis in a sample of 236 patients. Results: The results showed that 58 (56.9%) patients had low, 15 (14.7%) had intermediate, and 29 (28.4%) had a high probability of PH. We observed a negative association between right ventricular free wall strain (RV-FWS) and atrial global strain with sPAP. With the increase in PH severity, RA reservoir, conduit, and contraction (booster) strain values decreased. The identified cut-off values of strain parameters had an adequate ability to detect PH severity categories. In addition, the post-mortem biopsies of right heart chambers from subjects with known severe PH were analyzed to quantify myocardial fibrosis. Our sample of right heart biopsies (n = 12) demonstrated an association between increased sPAP before death and right ventricular and RA fibrosis. Conclusion: Mechanical dysfunction and fibrosis in the right chambers are associated with increased sPAP. Right ventricular and atrial strain could provide enhancement in the diagnosis and categorization of subjects with suspected PH.

Computed tomography assessment of saw-tooth cardiomyopathy: a case series.

BACKGROUND: Saw-tooth cardiomyopathy (STC) is an unusual type of left ventricular dysplasia. To our knowledge, six cases have been reported in the literature. Two new cases are presented with a review of all the case reports that have been published. CASE SUMMARY: Two patients with STC were examined. The first one was a 69-year-old woman with shortness of breath on mild exertion and chest pain, and the second was a 49-year-old man with a history of myocardial infarction who required stent implantation and is now asymptomatic. Both patients revealed findings of STC in the cardiac computed tomography (CT). DISCUSSION: When analysing the cases and comparing them to the ones reported in the literature; STC is a generally benign heart disease, although the clinical spectrum can range from asymptomatic to heart failure. Imaging studies such as cardiac magnetic resonance and cardiac CT are essential for the diagnosis.

Right Atrial and Right Ventricular Function Assessed by Speckle Tracking in Patients with Inferior Myocardial Infarction.

Background: In patients with inferior myocardial infarction (MI), involvement of the right chambers has a prognostic impact. The objective of this study was to evaluate the influence of left ventricular (LV) inferior wall MI in the right atrial (RA), and right ventricular (RV) longitudinal strain (LS) by 2D speckle tracking echocardiography (STE). Methods: 60 consecutive patients who underwent myocardial perfusion (MP) gated SPECT for chest pain were included. We studied 30 patients with LV inferior MI and 30 control subjects with normal MP. RV ejection fraction was measured by 3D transthoracic echocardiography, RV-free wall LS and RA reservoir, contraction, and conduit phases strain were analyzed by 2D speckle tracking echocardiography (STE). Results: The median age in the LV inferior MI was 65 (54-70) years, 27% had a transmural myocardial infarction and 47% had residual myocardial ischemia, most of them, mild (36.7%). RV-free wall LS (-26.1 vs -30.3, p < 0.01), RA LS-reservoir phase (31.5 vs 56.2, p < 0.01), and RA-conduit phase LS (12.5 vs 35, p = 0.01) were significantly lower in the LV inferior MI patients compared to control subjects. In a logistic regression model, the MI of the LV reduced the 3D ejection fraction of both ventricles, mitral regurgitation, and pulmonary hypertension were associated with a decrease in RV LS and RA LS. Conclusions: This study shows that RV free wall LS, RA peak strain (reservoir phase), and RA conduit phase strain were significantly lower in patients with LV inferior MI vs control individuals. Subclinical extension to the RV in the inferior MI of the LV and its role in the longitudinal strain of RA could be determined using speckle tracking echocardiography.

Case Report: A Rare Case of a Ventricular Perivascular Epithelioid Cell Tumor With Histologic Characteristics That Resembled a Primary Cardiac Rhabdomyoma.

We present the case of a young male patient with an initial diagnosis of a rhabdomyoma that was surgically treated at a different hospital when he was 17. After a 2-year disease-free period, the patient presented another intra-cardiac mass. He refused surgical treatment and died 5 years later. Post-mortem immunochemistry studies of both tumors led to the diagnosis of a primary malignant cardiac PEComa with histopathologic characteristics that resembled a rhabdomyoma with abundant "spider cells."
