Impact of COVID-19 pandemic on cardiometabolic patients without SARS CoV-2 infection in Latin America
No full textA cross-sectional survey including 38 questions about demography, clinical condition, changes in health habits, and medical treatments for cardiometabolic patients in outpatient follow-up was conducted. From June 15 to July 15, 2020, a total of 13 Latin-American countries participated in enrolling patients. These countries were divided into 3 geographic regions: Region 1 including North, Central, and Caribbean Regions (NCCR), Region 2 including the Andean Region (AR), and Region 3 including the Southern Cone Region (SCR). 4.216 patients were analyzed, resulting in a coefficient of 33.82%, 32.23%, and 33.94% for NCCR, AR, and SCR, respectively. Significant differences were found between the AR, SCR, and NCCR regions. The analysis of habitual medication usage showed that discontinued use of medication was more present in AR, reaching almost 30% (p < 0.001). The main finding of this study was the negative impact that restrictive measures have on adherence to medications and physical activity: Rs = 0.84 (p = 0.0003) and Rs = 0.61 (p = 0.0032), respectively. AR was the most vulnerable region. Restrictive quarantine measures imposed by the different countries showed a positive correlation with medication discontinuation and a negative correlation with physical activity levels in patients analyzed. These findings characterize the impact of the consequences left by this pandemic. Undoubtedly, restrictive measures have been and will continue to have reverberating negative effects in most Latin-American countries.Fil: Camiletti, Jorge.

ECG Artifact by a Spinal Cord Neurostimulator: A Case Report
No full textBackground: Neurostimulator devices produce electrical oscillations that may prevent accurate diagnosis of an ECG.
The Case: We present the case of a 68-year-old man who came to the emergency department with chest pain and a spinal cord neuromodulator device in situ to treat his polymyalgia rheumatica. A 12-lead ECG was obtained to determine the cause of the chest pain, and atrial fibrillation was wrongly diagnosed.
Conclusion: This case reiterates the value of recognizing this uncommonly encountered ECG artifact to avoid unnecessary mistakes in interpretation of heart rhythms

Comparative study of maternal and perinatal outcomes between elective and emergency caesarean section in term pregnancy at a tertiary care centre
No full textBackground: One of the most common surgical procedures done worldwide is the Caesarean section. The goal of the current study is to ascertain the problems and outcomes for mothers and newborns in two groups of pregnant women who had elective and emergency caesarean sections. So that measures can be taken to reduce morbidity and mortality in near future.
Methods: A prospective comparative observational study carried out in department of Obstetrics and Gynecology, Jawaharlal Nehru Hospital and Research Centre, Bhilai, Chhattisgarh. All patients who underwent caesarean section are divided into two groups elective and emergency. Two groups were compared on the basis of different parameters like age, parity, booking status, indication, maternal and neonatal complications.
Results: The incidence of caesarean section was 51.15%. The proportion of elective and emergency CS was 39.55% and 60.44% respectively. Most of the complications were more common in emergency group.
Conclusions: The incidence of caesarean section is high in JLNH&RC, Bhilai and overall complication rate was more common in emergency group
A Blueprint for High Altitude Acclimatization Prior to High Altitude Competition for Professional Athletes
No full textIntroduction: Among professional athletes, high altitude training is a popular technique due to its documented success on improving cardiovascular health and athletic performance. Nevertheless, there is little consensus on the guidelines for high altitude training and competition. This review sought to summarize existing literature for acclimatization recommendations for competing at high altitudes and suggests a blueprint that could be followed by athletes and trainers.
Methods: This paper is part of the Altitude Nondifferentiated ECG Study (ANDES) project. A non-systematic search was conducted using Pubmed, EMBASE and MEDLINE databases.
Results: Six studies were included, all of which recommended a gradual ascent before competition. The duration of acclimatization ranged from 4 days to 2 weeks depending on the magnitude of ascent. Athletes are encouraged to have pre-ascent assessments of ferritin, transferrin, hemoglobin mass, ECG, and weight with close monitoring of adverse altitude-induced complications.
Conclusion: This study provides insight on key recommendations for athletes and trainers to consider when training and competing at high altitudes. These strategies can optimize athletic performance and mitigate deleterious altitude effects that can hinder functionality and training
Alcohol and cardiovascular disease.
No full textAlcohol's impact on cardiovascular health is biphasic: low-to-moderate intake may appear protective, but excessive or binge drinking causes significant harm. This review examines mechanisms linking overconsumption to cardiovascular disease. Acute heavy drinking can trigger "Holiday Heart Syndrome," a transient atrial arrhythmia from electrophysiological instability, autonomic imbalance, and electrolyte shifts. Chronic excess contributes to alcoholic cardiomyopathy via oxidative stress, mitochondrial dysfunction, and impaired calcium handling. Alcohol also promotes atrial fibrillation and hypertension by inducing atrial fibrosis, neurohormonal dysregulation, and endothelial injury. Excessive intake accelerates coronary artery disease and type 2 diabetes through dyslipidemia, vascular inflammation, and insulin resistance, raising risks of stroke, heart failure, and myocardial infarction. While moderate consumption was once thought cardioprotective, emerging evidence-especially for atrial fibrillation-suggests risks may outweigh benefits. In conclusion, public health guidance increasingly emphasizes moderation, individualized assessment, and avoiding binge patterns, particularly for those with underlying cardiovascular vulnerabilities
The psychological impact of implantable cardioverter defibrillators: a narrative review
No full textImplantable cardioverter defibrillators (ICDs) are critical to the prevention of sudden cardiac death caused by life-threatening arrhythmias such as ventricular tachycardia and fibrillation. While their clinical value is well-established, the psychological impact of living with an ICD remains underrecognized. Patients often experience anticipatory anxiety, depression, Post-Traumatic Stress Disorder (PTSD), and reduced quality of life. These challenges can begin before implantation, persist after both appropriate and inappropriate shocks, and be worsened by fears of device malfunction, recalls, or cybersecurity risks. Many patients alter postimplantation behaviors, avoiding physical activity and reporting diminished trust in medical technology. The burden is especially significant in children, alongside those who experience multiple or unnecessary shocks. Despite increased awareness, mental health care remains poorly integrated into cardiology. Cognitive Behavioural Therapy (CBT), structured patient education, and transparent communication around device updates and recalls have shown effectiveness. In conclusion, addressing this gap is essential to improving outcomes and quality of life.</p
Casey-Wilkins Adaptable Array: Broadband Seismic Data
No full textProgress Code: onGoingStatement: The data are generally of high quality, with many stations running overwinter. A small number of stations are impacted by recorder failure or adverse site conditions (e.g. solar panels becoming obscured by snow, or the site being impacted by melt).<b>Purpose</b><br/>Diverse passive seismic studies including, but not limited to: the background seismic wavefield of the Southern Ocean across annual cycles, the ice-bedrock interface zone in the Casey-Wilkins area, cryoseismic signals of Wilkes Land, teleseismic studies informing the upper mantle structure of East Antarctica, teleseismic studies informing deep Earth structure.
Seismic studies in Antarctica inform the structure and character of the plate tectonic foundations of the continent, including the likelihood of geothermal anomalies and relict fault zones impacting sub-ice fluid and energy flows. Given the low number of seismic stations in Antarctica, recordings at these sites enable studies of the crust and deeper Earth, in tandem with Global Seismic Network records. Such data also informs the structure and character of the ice-bedrock interface zone, including the presence of sediments, whether frozen or otherwise, and the saturation of those sediments. Seismic arrays afford the ability to make accurate appraisals of the distance and direction of diverse aspects of the global seismic wavefield, informing interdisciplinary studies of the Southern Ocean wave climate, for example.
The data are in miniseed format, which is a global standard (not proprietary). Data format information: https://ds.iris.edu/ds/nodes/dmc/data/formats/
The datafiles are time-series, and an example software to read the files would be,
