The Eye as the Window to the Heart: Optical Coherence Tomography Angiography Biomarkers as Indicators of Cardiovascular Disease

Alterations in microvasculature represent some of the earliest pathological processes across a wide variety of human diseases. In many organs, however, inaccessibility and difficulty in directly imaging tissues prevent the assessment of microvascular changes, thereby significantly limiting their translation into improved patient care. The eye provides a unique solution by allowing for the non-invasive and direct visualization and quantification of many aspects of the human microvasculature, including biomarkers for structure, function, hemodynamics, and metabolism. Optical coherence tomography angiography (OCTA) studies have specifically identified reduced capillary densities at the level of the retina in several eye diseases including glaucoma. This narrative review examines the published data related to OCTA-assessed microvasculature biomarkers and major systemic cardiovascular disease. While loss of capillaries is being established in various ocular disease, pilot data suggest that changes in the retinal microvasculature, especially within the macula, may also reflect small vessel damage occurring in other organs resulting from cardiovascular disease. Current evidence suggests retinal microvascular biomarkers as potential indicators of major systemic cardiovascular diseases, including systemic arterial hypertension, atherosclerotic disease, and congestive heart failure.

Evaluation of the District Health Information System in District Kotli, Azad Jammu and Kashmir: A Retrospective Analysis.

It is essential to implement a high-quality electronic database for keeping important information. The District Health Information System (DHIS) is an active data-keeping system in Pakistan. This study aimed to evaluate the patients' data from the DHIS dashboard for the District Headquarters Hospital, Kotli, Azad Jammu and Kashmir (AJK). The data was requested from the hospital administration at District Headquarters Hospital, Kotli, AJK, and the data was analyzed after permission was granted. The data was given in two forms; one was a hard copy of the data for August and September and the other was a comma-separated values file for October and November, 2023. The highest frequency of patients was received in the department of emergency and trauma and the patient's median age was between 15 and 49 years. The second department was medicine with the >50 years of age. Common conditions that needed more attention were chronic obstructive pulmonary disease, acute respiratory infection, diarrhea, pneumonia, diabetes mellitus, hypertension, and ischemic heart disease. For nations with constrained healthcare systems and funds, primary health care (PHC) is the only viable approach for managing non-communicable diseases (NCDs). However, PHC systems intended for infectious diseases have not sufficiently adapted to the growing requirement of chronic care for NCD. Research using health information databases offers numerous benefits, such as the evaluation of large data sets and unexpected prevalence of disease in certain populations, such as a higher prevalence of disease in one gender or age group. Health information system-based data analysis or studies are less expensive and faster but lack scientific control over data collection.

Effect of chronic lung diseases on angina pectoris among Indian adults: longitudinal ageing study in India

The study aimed to evaluate the effect of chronic lung diseases, namely chronic obstructive pulmonary diseases (COPD) and asthma, on angina pectoris in individuals aged 45 years and above. Identifying vulnerable subpopulations suffering from COPD and asthma at higher risk of future cardiovascular events using the rose angina questionnaire is imperative for tailored primary and secondary prevention approaches. The present study utilizes the data from the Longitudinal Ageing Study in India, wave 1, conducted during 2017–2018. The sample size included 58,830 individuals aged 45 years and above. Angina was measured based on seven questions from Rose's questionnaires. Descriptive statistics and bivariate analysis were employed to examine the prevalence of angina among individuals with COPD and asthma. Further, multivariable logistic regression and propensity score matching (PSM) methods were used to assess the independent effect of COPD and asthma on angina after controlling the selected background characteristics. We employed PSM in two different models and included various additional factors in model 2, such as smoking, chewing tobacco, alcohol use, ADL, IADL, body mass index, physical activity, high cholesterol, hypertension, diabetes, and chronic heart disease. The current study shows that the prevalence of angina pectoris, COPD and asthma was 6.0%, 2.3% and 4.7%, respectively, among individuals aged 45 years and above in India. The prevalence of angina pectoris was higher among individuals with COPD (9.6% vs. 5.8%) and asthma (9.9% vs. 5.7%) than those without COPD and asthma, respectively. Additionally, angina pectoris was more prevalent among females and rural respondents with COPD (10.8% and 11.0%) and asthma (10.3% and 10.3%) compared to males and urban respondents with COPD (8.0% and 5.7%) and asthma (8.9% and 7.9%). Moreover, in the adjusted model, individuals with COPD (AOR 1.43, 95% CI 1.03 1.98) and asthma (AOR 1.44, 95% CI 1.17 1.77) had nearly 1.5-fold higher odds of having angina pectoris than those without COPD and asthma. The PSM estimates showed that individuals with COPD had 8.4% and 5.0% increased risk of angina pectoris compared to those without COPD in model 1 and model 2, respectively. We observed that, after adjusting to lifestyle, health-related and morbidity factors in model 2, both average treatment effect on untreated (ATU) and average treatment effect (ATE) values decreased by nearly 3.5%. Additionally, the PSM estimates demonstrated that individuals with asthma had a 3.4% and 2.9% increased risk of angina pectoris compared to those without asthma in model 1 and model 2, respectively. The study suggests that COPD and asthma are significantly associated with angina pectoris, and individuals with COPD and asthma have a higher risk of developing angina pectoris. Additionally, angina pectoris was more prevalent among females, rural respondents and adults aged 45–54 with COPD compared to males, urban respondents and those aged 65 and above, respectively, with COPD. Moreover, the findings of our study underscore the targeted primary and secondary interventions and team-based care approach among individuals with COPD and asthma to reduce the risk of CVD events in future.

HOSPITAL READMISSION AND MORTALITY RATES IN PATIENTS WITH CONCURRENT DEPRESSION AND INFLAMMATORY BOWEL DISEASE: INSIGHTS FROM THE NATIONAL READMISSIONS DATABASE, 2016–2019

Abstract BACKGROUND Inflammatory Bowel Disease (IBD) is a proinflammatory condition that is known to be associated with depression. Research examining causality suggests that Crohn's disease (CD) or ulcerative colitis (UC) patients are vulnerable to triggering pre-existing mental health conditions and that conversely, a pre-existing disorder such as depression may have an effect on the disease process and course of IBD. There is a paucity of comprehensive studies examining the downstream effects of depression on patients with IBD such as readmission rates and mortality. The complexity of the interaction between depression and IBD remains a fertile ground for further investigations in terms of pathological reciprocity and downstream consequences. METHODS In this retrospective observational study, patients were queried from the National Readmissions Database from 2016 to 2019. ICD-10 codes were used to identify patients with Crohn’s disease, ulcerative colitis, and depression. Primary outcomes were mortality and readmission rates at 30 days and 90 days. Secondary outcomes were index admission mortality, hospital length of stay (LOS), and total hospitalization charges (TOTHC) at 30 and 90 days respectively. The top 10 readmission diagnoses in each subgroup were also identified. RESULTS For patients with CD and depression, the mean age at readmission was 51.6 years with a high readmission and mortality rate at 30 days (readmission rate 5.2%, p<0.01; mortality rate 2.8%, p<0.01) which increased significantly at 90 days (readmission rate 8.4%, p<0.01). Hospital LOS and TOTHC remained relatively the same compared to the index admission for both 30-day and 90-day readmissions (Table 1,2). A similar trend was seen for UC and depression as well: mean age at readmission was 51.4 years with a high readmission rate and mortality at 30 days (readmission rate 5.0%, p<0.01; mortality rate 2.6%, p<0.01) which increased significantly at 90 days (readmission rate 8.4%, p<0.01; mortality rate 2.9%, p<0.01). Sepsis, hypertensive heart disease accompanied by heart failure and/or chronic kidney disease, acute kidney injury, hypoxia, and acute depressive episodes were the top primary associated readmission etiologies at 30 days and 90 days when correlated with a diagnosis of UC or CD. (Table 1, 2). CONCLUSION Our investigation revealed that patients affected by both depression and either UC or Crohn’s disease exhibited elevated readmission rates and a notably amplified mortality risk at 30 days post-readmission, with a more substantial increase observed at the 90-day mark. These findings underscore the significance of healthcare providers routinely screening for depression, addressing the management of mental health, and acknowledging the considerable impact it has on patients with co-occurring chronic diseases like UC or CD as an integral facet of comprehensive care.

Clinical characteristics of obstructive sleep apnea in patients with heart failure

Aims: To investigate the clinical characteristics of obstructive sleep apnea syndrome in patients with heart failure (HF).
 Patients and Methods: From 9/2020 to 9/2021, patients with chronic HF (European Society of Cardiology’s criteria) and obstructive sleep apnea (American Academy of Sleep Medicine’s criteria) were enrolled into the study. Clinical examination, blood test, echocardiography, polysomnography, ventilatory polygraphy were performed in all patients.
 Results: 63 patients were included: 54 male (85.7%), 9 female (14.3%), age 69.57 ± 13.08, BMI 28.63 ± 4.16 kg/m2, neck size >40 cm: 69.3%, 100% male and 88.9% female had waist circumference ≥90 cm, hypertension 78.4%, diabetes 47.6%, HFrEF 12 (18%), HFmrEF 5 (7.9%), HFpEF 46 (73%). 68.3% patients had Epworth ≥10, snoring 92.1%. Compared to patients with apnea-hypopnea index (AHI) <15 and AHI 15-30, patients with AHI>30 had thicker interventricular septum, higher left ventricular mass (LVM) and LVM index, lower e’ velocity, higher E/e’ ratio, higher left atrial volume index, higher systolic artery pulmonary pressure, p<0.05. Multivariate regression showed that age, body mass index, neck size, HbA1C were independent predictors of high AHI, p<0.05.
 Conclusions: Majority of patients with chronic HF and obstructive sleep apnea were male, old age, overweight/obesity, and had large neck size. Hypertension and diabetes and heart failure with preserved ejection fraction were prevalent. Patients with AHI>30 had higher interventricular septal thickness, higher LVM and LVM index, lower e’ velocity, higher E/e’ ratio, higher left atrial volume index, higher systolic artery pulmonary pressure, p<0.05. Age, body mass index, neck size, HbA1C were independent predictors of high AHI, p<0.05.

Negative effects of COVID-19 on the implantation rate of cardiac resynchronization therapy with defibrillator device.

COVID-19 drastically impacted the landscape of the United States' medical system. Limited data is available on the nationwide implantation trends in Cardiac Resynchronization Therapy Defibrillator (CRT-D) devices before and during the pandemic. We aimed to explore the impact of the COVID-19 pandemic on CRT-D insertion rates and adverse outcomes related to delays in care. We conducted a retrospective cross-sectional analysis using the National Inpatient Sample database between 2017 and 2020. Variables were identified using their ICD-10 codes. Inclusion criteria: age ≥ 18 years, presenting for a nonelective admission, primary diagnosis of hypertensive heart disease, hypertensive heart, chronic kidney disease, or heart failure, and underwent insertion of a CRT-D. Between 2017 and 2020, CRT-D devices were inserted during 23,635 admissions. On average, 6198 devices were implanted yearly from 2017 to 2019, with only 5040 devices being implanted in 2020. Additionally, reduced implantation rates were noted for every cohort of hospital size, location, and teaching status during this year. The year 2020 also had the highest average death rate at 1.39%, but this difference was statistically insignificant (adjusted Wald test p = .767), and COVID-19 was not associated with an increased risk of inpatient mortality (OR 0.22, 95% CI 0.03-1.82, p = .162). The COVID-19 pandemic has affected all facets of the healthcare system, especially surgical volume rates. CRT-D procedures significantly decreased in 2020. This is the first retrospective study highlighting the trend of reduced rates of CRT-D implantation as a response to the COVID-19 pandemic.

Hypertensive Heart Disease: A Narrative Review Series-Part 3: Vasculature, Biomarkers and the Matrix of Hypertensive Heart Disease.

Over the last few decades, research efforts have resulted in major advances in our understanding of the pathophysiology of hypertensive heart disease (HHD). This is the third part of a three-part review series. Here, we focus on the influence of high blood pressure on the micro- and macroalterations that occur in the vasculature in HHD. We also provide an overview of circulating cardiac biomarkers that may prove useful for a better understanding of the pathophysiology, development and progression of HHD, and may play a unique role in the diagnostic and prognostic evaluation of patients with HHD, taking into account their properties showing as abnormal long before the onset of the disease. In the conclusion, we propose an updated definition of HHD and a matrix for clinical classification, which we suspect will be useful in practice, allowing an individual approach to HHD patients.

Association of birthweight with diabetes, hypertension, and ischemic heart disease in young adulthood: a retrospective cohort study.

Birthweight has been associated with diabetes in a reverse J-shape (highest risk at low birthweight and moderately high risk at high birthweight) and inversely associated with hypertension in adulthood with inconsistent evidence for cardiovascular disease. There is a lack of population-based studies examining the incidence of cardiometabolic outcomes in young adults born with low and high birthweights. To evaluate the association between birthweight and diabetes, hypertension, and ischemic heart disease (IHD) in young adulthood, we conducted a retrospective cohort study of 874,904 singletons born in Ontario, Canada, from 1994 to 2002, identified from population-based health administrative data. Separate Cox regression models examined birthweight in association with diabetes, hypertension, and IHD adjusting for confounders. Among adults 18-26 years, the diabetes incidence rate was 18.15 per 100,000 person-years, hypertension was 15.80 per 100,000 person-years, and IHD was 1.85 per 100,000 person-years. Adjusted hazard ratios (AHR) for the hazard of diabetes with low (<2500g) and high (>4000g), compared with normal (2500-4000g) birthweight, were 1.46 (95% CI 1.28, 1.68) and 1.09 (0.99, 1.21), respectively. AHR for hypertension with low and high birthweight were 1.34 (1.15, 1.56) and 0.86 (0.77, 0.97), respectively. AHR for IHD with low and high birthweight were 1.28 (0.80, 2.05) and 0.97 (0.71, 1.33), respectively. Overall, birthweight was associated with diabetes in young adults in a reverse J-shape and inversely with hypertension. There was insufficient evidence of an association with IHD. Further evidence is needed to understand the causal mechanisms between birthweight and cardiometabolic diseases in young adults.

Contribution of Left Ventricular Diastolic Dysfunction to Survival and Breathlessness in Systemic Sclerosis-Associated Interstitial Lung Disease.

To explore the effect of left ventricular (LV) diastolic dysfunction (LVDD) in systemic sclerosis (SSc)-associated interstitial lung disease (ILD), and to investigate SSc-specific associations and clinical correlates of LVDD. There were 102 Australian Scleroderma Cohort Study participants with definite SSc and radiographic ILD included. Diastolic function was classified as normal, indeterminate, or abnormal according to 2016 American Society of Echocardiography/European Association of Cardiovascular Imaging guidelines for assessment of LV diastolic function. Associations between clinical features and patient- and physician-reported dyspnea were evaluated using logistic regression. Survival analyses were performed using Kaplan-Meier survival estimates and Cox regression modeling. LVDD was identified in 26% of participants, whereas 19% had indeterminate and 55% had normal diastolic function. Those with ILD and LVDD had increased mortality (hazard ratio 2.4, 95% CI 1.0-5.7; P = 0.05). After adjusting for age and sex, those with ILD and LVDD were more likely to have severe dyspnea on the Borg Dyspnoea Scale (odds ratio [OR] 2.6, 95% CI 1.0-6.6; P = 0.05) and numerically more likely to record World Health Organization Function Class II or higher dyspnea (OR 4.2, 95% CI 0.9-20.0; P = 0.08). Older age (95% CI 1.0-6.4; P = 0.05), hypertension (OR 5.0, 95% CI 1.8-13.8; P < 0.01), and ischemic heart disease (OR 4.8, 95% CI 1.5-15.7; P < 0.01) were all associated with LVDD, as was proximal muscle atrophy (OR 5.0, 95% CI 1.9-13.6; P < 0.01) and multimorbidity (Charlson Comorbidity Index scores ≥ 4, OR 3.0, 95% CI 1.1-8.7; P = 0.04). LVDD in SSc-ILD is more strongly associated with traditional LVDD risk factors than SSc-specific factors. LVDD is associated with worse dyspnea and survival in those with SSc-ILD.

Perspektif Masyarakat terhadap Terjadinya Diabetes Melitus dan Hipertensi di Desa Sembahe Kecamatan Sibolangit Kabupaten Deli Serdang

Diabetes Mellitus is condition when blood glucose in the body is not controlled due to impaired sensitivity of pancreatic cells to produce the hormone insulin. Hypertension is a common public health problem in developing countries. Hypertension that is not treated immediately has an impact on the emergence of degenerative diseases, such as heart disease (Hypertension Heart Disease), end-stage renal failure (End Stage Renal Disease), and peripheral vascular disease. Risk factors such as heart disease, hypertension, dyslipidemia, Diabetes Mellitus (DM) should be monitored regularly so as not to cause more serious complications. This paper describes the implementation and evaluation of the achievement of minimum service standards and to find out how the characteristics of patients with diabetes are and to find out how the relationship between blood sugar levels and blood pressure of patients with diabetes type mellitus in health sector cases of hypertension and Diabetes Mellitus (DM) in Sembahe Village, Sibolangit District, Deli Serdang Regency. The method used is a qualitative study with a phenomenological method approach, with the focus of the research on clean and healthy living behavior towards the occurrence of hypertension and diabetes mellitus. The results of this study indicate that it is important to know and prevent hypertension and diabetes mellitus from an early age. With seminars and counseling or education regarding hypertension and diabetes mellitus, this has been carried out for 1 month with the assistance of the Field Supervisor, the village midwife of worship and colleagues-his partner. Door to door counseling, healthy gymnastics and health checks have also been carried out once a month to find out how the health condition of the worshipers is.

Global prevalence of cardiovascular diseases by gender and age during 2010-2019.

The aim of this study was to evaluate the global, gender, and age-related cardiovascular disease (CVD) burden during 2010-2019. Not only the global trend in the prevalence of CVDs was studied but also whether there was a statistically significant difference between genders and ages during 2010-2019. Detailed information from 2010 to 2019, including global rates of prevalence of 11 categories of CVD, was collected from the Global Burden of Disease Study 2019. The statistical methods used to analyze the results of this study are the independent samples t-test and one-way analysis of variance (ANOVA) test. The global prevalence rate of CVDs increased from 0.061% in 2010 to 0.070% in 2019. There was a statistically significant difference in prevalence rates between genders in all cardiovascular diseases except atrial fibrillation and flutter. Females have higher prevalence rates of CVDs worldwide. Moreover, females have statistically significantly higher prevalence rates of stroke, hypertensive heart disease, rheumatic heart disease, non-rheumatic valvular heart disease, endocarditis, peripheral artery disease and other cardiovascular and circulatory diseases globally. On the other hand, males have statistically significantly higher prevalence rates of cardiomyopathy and myocarditis, and ischemic heart disease globally. Rheumatic heart disease has a statistically significantly higher prevalence rate in the age group of 25-49 years than the other age groups. The significance of this study is not only that it has succeeded in evaluating the global, gender, and age-related cardiovascular disease (CVD) burden, finding statistically significant associations, but it is also the only study to achieve this goal in the last decade.

The role of laboratory markers in predicting the effectiveness of catheter treatment for atrial fibrillation: a literature review

Atrial fibrillation (AF) is the most common cardiac arrhythmia among the adult population. There are many possible causes of AF: structural heart disease, inflammatory and autoimmune diseases, obesity, alcohol abuse, diabetes mellitus, obstructive sleep apnea and old age. The ectopic activity of pulmonary vein couplings lies in the pathogenesis of paroxysmal and persistent forms of AF. The role of AF itself in triggering the inflammatory process in the atrium myocardium has also been proven. Despite the large amount of existing data, the search for the causes of AF continues. Previously, AF was considered the outcome of prolonged hemodynamic stress, arterial hypertension and valvular heart disease. Recently, views on the pathogenesis of AF have changed, since patients with metabolic diseases, without hypertrophy and dilatation of the left ventricle, but with disturbances in the structure and function of the atria, most often the left atrium, are increasingly encountered. There is an active search for laboratory markers to identify groups of patients most susceptible to developing AF. Determining the cause of atrial fibrillation and pathogenesis in each patient is important for selecting therapy and determining treatment tactics. Currently, a search is underway for laboratory markers that may be associated with the manifestation of atrial fibrillation, with atriopathy, and the effectiveness/ineffectiveness of catheter treatment for atrial fibrillation. An analysis of clinical studies was carried out based on articles indexed in the Scopus, VAK, Russian Science Citation Index, PubMed, and Web of Science databases.

Age-Stratified Sex Differences in Heart Failure With Preserved Ejection Fraction Among Adult Hospitalizations.

There is evidence that heart failure with preserved ejection fraction (HFpEF)-related hospitalizations are increasing in the United States. However, there is a lack of knowledge about HFpEF-related hospitalizations among younger adults. The aims of this study were to perform a retrospective analysis using the Nationwide Inpatient Sample and to examine age-stratified sex differences in the prevalence, correlates, and outcomes of HFpEF-related hospitalization across the adult life span. Using the Nationwide Inpatient Sample (2002-2014), patient and hospital characteristics were determined. Joinpoint regression was used to describe age-stratified sex differences in the annual average percent change of hospitalizations with HFpEF. Survey logistic regression was used to estimate adjusted odds ratios representing the association of sex with HFpEF-related hospitalization and in-hospital mortality. There were 8 599 717 HFpEF-related hospitalizations (2.43% of all hospitalizations). Women represented the majority (5 459 422 [63.48%]) of HFpEF-related adult hospitalizations, compared with men (3 140 295 [36.52%]). Compared with men younger than 50 years, women within the same age group were 6% to 28% less likely to experience HFpEF-related hospitalization. Comorbidities such as hypertensive heart disease, renal disease, hypertension, obstructive sleep apnea, atrial fibrillation, obesity, anemia, and pulmonary edema explained a greater proportion of the risk of HFpEF-related hospitalization in adults younger than 50 years than in adults 50 years or older. Before the age of 50 years, women exhibit lower HFpEF-related hospitalization than men, a pattern that reverses with advancing age. Understanding and addressing the factors contributing to these sex-specific differences can have several potential implications for improving women's cardiovascular health.

Clinical Review of Hypertensive Acute Heart Failure.

Although acute heart failure (AHF) is a common disease associated with significant symptoms, morbidity and mortality, the diagnosis, risk stratification and treatment of patients with hypertensive acute heart failure (H-AHF) still remain a challenge in modern medicine. Despite great progress in diagnostic and therapeutic modalities, this disease is still accompanied by a high rate of both in-hospital (from 3.8% to 11%) and one-year (from 20% to 36%) mortality. Considering the high rate of rehospitalization (22% to 30% in the first three months), the treatment of this disease represents a major financial blow to the health system of each country. This disease is characterized by heterogeneity in precipitating factors, clinical presentation, therapeutic modalities and prognosis. Since heart decompensation usually occurs quickly (within a few hours) in patients with H-AHF, establishing a rapid diagnosis is of vital importance. In addition to establishing the diagnosis of heart failure itself, it is necessary to see the underlying cause that led to it, especially if it is de novo heart failure. Given that hypertension is a precipitating factor of AHF and in up to 11% of AHF patients, strict control of arterial blood pressure is necessary until target values are reached in order to prevent the occurrence of H-AHF, which is still accompanied by a high rate of both early and long-term mortality.

In-Hospital Onset of Transient Myoclonic State in Older Adults: A Case Report.

Transient myoclonic (TM) state in older adults is a neurological condition characterised by short-lived, repetitive myoclonus without consciousness disturbance. First reported in 1992, it predominantly affects older individuals with chronic diseases. Despite its clear symptomatology, TM often remains under-recognised, leading to potential misdiagnoses. We report a case of a 68-year-old woman with a history of chronic heart failure who developed TM during hospitalisation following medication adjustment for acute heart failure. The patient, who had no history of intracranial disease or epilepsy, experienced acute involuntary movements of the face and limbs three days after diuretic adjustment. She responded well to intravenous diazepam and oral clonazepam, with no recurrence of symptoms post-treatment. TM presents with bilateral, irregular, and repetitive myoclonus, mostly affecting the head, neck and upper extremities. Diagnosis is clinical, based on symptomatology and normal laboratory results. This case underscores the importance of recognising TM in differential diagnosis, especially in older patients in the acute or recovery phase of infection, or with medication changes. The potential role of fluid volume changes in TM pathophysiology in patients with underlying conditions such as hypertension or chronic heart failure is also highlighted. This case emphasises the need for heightened awareness and knowledge of TM among healthcare professionals. TM, though rare, requires awareness among clinicians for accurate diagnosis and management. It is crucial to avoid misdiagnosis and unnecessary interventions, and to provide appropriate information during care transitions, particularly in older adults with chronic conditions. Transient myoclonic (TM) state is a rare neurological condition in older adults, characterised by brief and repetitive myoclonus, primarily affecting the head, neck and upper extremities.The distinctive clinical diagnostic feature is myoclonus occurring without disturbances in consciousness, without amnesia or paralysis, while retaining the ability to perform directed movements. This condition can manifest at rest, may worsen with posture or movement, and tends to improve during sleep.Management strategies include ensuring smooth care transitions, avoiding misdiagnosis and educating patients and families about the risk of recurrence.

What have we learned from the real-world efficacy of FFA in DS and LGS? A post-marketing study in clinical practice

ObjectiveTo evaluate the effectiveness and tolerability of fenfluramine (FFA) in routine clinical practice treating real-world populations with Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS). MethodsThis was a retrospective analysis of patients with DS or LGS who initiated FFA treatment from 2018 to 2022 at a single center. Patient demographics, medical history, seizure characteristics, and treatment outcomes were collected from electronic medical records. Duration of FFA treatment, dosage regimens, seizure frequency, seizure severity, improvements in cognitive, social, and motor outcomes, and adverse events were extracted and analyzed. Effectiveness was assessed using ≥50 % sustained reduction in monthly seizure frequency vs baseline for ≥2 consecutive months at 12 months; seizure freedom was a secondary measure. ResultsSeizure frequency data was available for 56 of 68 patients included in the study. At 12 months, 50 patients (89.3 %) remained on FFA treatment; 58 % of these patients achieved a ≥50 % sustained response and 10 % experienced seizure freedom. Cognitive, motor, and social improvement were noted in 70.7 %, 36.2 %, and 27.6 % of patients, respectively. The total number of concomitant antiseizure medications was reduced by ≥1 in 29.4 % of patients. No differences were found between DS and LGS patients in these outcomes; age at start of FFA and age at the 12-month timepoint did not have an effect.At least one AE was experienced by 59.7% of patients; in 86.5% of the cases, AEs were plausibly related to treatment. While 70.3% of AEs were self-resolving and 81.8% of the remaining patients experienced mild AEs, 1 patient experienced a serious AE unrelated to FFA which resulted in the patient’s death. There were no cases of pulmonary arterial hypertension or ventricular heart disease. SignificanceThe effectiveness and tolerability of FFA treatment in patients with DS or LGS in this retrospective analysis of real-world data were consistent with those seen in randomized clinical trials.

An updated review of experimental rodent models of pulmonary hypertension and left heart disease.

Left heart disease (LHD) is the leading cause of pulmonary hypertension (PH). Its recent growth has not been matched by the design of therapeutic agents directly targeting the disease. Effective therapies approved for pulmonary arterial hypertension (PAH) have been shown to be inefficient in patients with PH-LHD. Hence, there is a need for an animal model that would closely mimic PH-LHD in preclinical experiments. The current study describes and compares a number of rodent models of left ventricular failure and their potential to induce PH. It also evaluates whether, and to what extent, common PH models could develop LV failure. Articles were identified in the Pubmed/Medline and Web of Science online electronic databases following the PRISMA Protocol between 1992 and 2022. Quality assessment was carried out using the SYRCLE risk-of-bias tool for animal studies. Publication bias across studies using Egger's regression test statistic, was performed together with sensitivity analysis. A wide spectrum of protocols-135 studies and 207 interventions, was examined, including systemic hypertensive models, pressure-overload-induced HF, model of ischemic heart failure, and metabolic approaches based on high fat diet or metabolic syndrome. The most pronounced alterations in PH-related parameters were demonstrated for the common PH models, but were also seen in animals with LV failure induced by ischemic conditions, pressure overload or metabolic conditions. Models based on aortic banding, transverse aortic constriction (TAC), or with myocardial infarction (MI) caused by coronary artery ligation, demonstrated more pronounced worsening in PH due to LV failure; however, they also demonstrated poor survival, especially the ischemic-HF model. Common PH models, excluding prolonged exposure to monocrotaline, do not promote LV hypertrophy. Prolonged exposure to a high-fat diet, or a two-hit model of an obese ZSF1 rat combined with SU5416-induced pulmonary endothelial impairment (a VEGF receptor antagonist) worsened PH and impaired diastolic dysfunction. Due to the limited number of protocols, further trials are needed to confirm the utility of such approaches for modeling PH in subjects with metabolic syndrome. This would provide a clearer insight into the complexity of LHD, PH and metabolic disorders in PH-LHD, and thus accelerate the development of new therapies in clinical trials.

Persistence of severe global inequalities in the burden of Hypertension Heart Disease from 1990 to 2019: findings from the global burden of disease study 2019

AimsAssessing the global burden and health inequalities of Hypertension Heart Disease (HHD) during the period from 1990 to 2019.MethodsSecondary analysis of the Global Burden of Disease (GBD) study in 2019, focusing on the burden of diseases, injuries, and risk factors worldwide. Disability-Adjusted Life Years (DALYs) data related to HHD are extracted from the 2019 GBD. Inequality Slope Index (SII) and Concentration Index are calculated to assess health inequalities across regions and countries.ResultsThe total DALYs for HHD reached 21.51 million, demonstrating a substantial increase of 54.25% compared to the figures recorded in 1990, while the age-standardized DALY rates per 100,000 population for HHD in 2019 showed a notable decline to 268.19 (95% UI 204.57, 298.07), reflecting a significant decrease of 26.4% compared to the rates observed in 1990. The DALYs rate of hypertensive heart disease increases with age. Countries with moderate SDI accounted for 38.72% of the global burden of HHD in terms of DALYs. The highest age-standardized DALY rates (per 100,000) are predominantly concentrated in underdeveloped areas. In 1990 and 2019, the SII (per 100,000 population) for DALYs were − 121.6398 (95% CI -187.3729 to -55.90684) and − 1.592634 (95% CI -53.11027 to 49.925) respectively. The significant decline suggests a reduction in the inequality of age-standardized burden of HHD between high-income and low-income countries during this period.ConclusionThe unequal prevalence of HHD across different populations can hinder the achievement of the “health for all” objective. Persistent disparities in HHD have been observed globally over the past thirty years. It is crucial to prioritize efforts towards reducing avoidable health inequalities associated with hypertension-related heart disease, particularly in low-income and middle-income countries.

Epidemiological survey of elderly patients diagnosed with COVID-19 at mobile field hospitals.

During the COVID-19 pandemic, the mobile field hospital, a rapidly deployable healthcare facility for emergency care, was effective in ensuring rapid diagnosis and treatment of patients with mild or asymptomatic SARS-CoV2 infections, effectively preventing the spread of COVID-19. We conducted a survey to gain a thorough understanding of the epidemiological traits among the elderly who contracted the Omicron variant of the SARS-CoV-2 virus at a mobile field hospital set up at the National Exhibition and Convention Center (Shanghai). A cross-sectional study approach was employed to examine various factors such as demographic characteristics, clinical features, vaccination status, and nucleic acid testing. We utilized the DezhenTech Integrated Electronic Medical Record Platform (Municipal Isolation Hospital) to collect data and focused on elderly individuals infected with COVID-19 in the fifth isolation zone of the mobile field hospital set up at the National Exhibition and Convention Center (Shanghai). The patients were categorized into different age groups for analysis. Among the 3,183 elderly patients, 54.7% were males and 45.3% were females, with an average age of 65.32 ± 4.41years. Among them, 47.8% (1523/3183) were 60-64 years old, 34.0% (1082/3183) were 65-69 years old, 14.0% (444/3183) were 70-74 years old, 3.2% (103/3183) were 75-79 years old, and 1.0% (31/3183) were ⩾ 80 years old. The majority (95.7%) of the elderly patients with chronic conditions had hypertension, diabetes, and coronary heart disease. The first viral nucleic acid screening showed a higher positive rate in the community and hospital fever clinics. The cumulative positive rate of the nucleic acid test in the mobile field hospital was 38.7%. The average CT value of the COVID-19 ORF1ab gene was 34.56 ± 5.98, while the average CT value of the N gene was 33.10 ± 6.50. The patients took an average of 3.40 ± 0.45 days to test negative, with a positive rate of 15.4% and an average hospital stay of 7.45 ± 0.53 days. The overall rate of COVID-19 vaccine coverage was 68.0%, with an enhanced coverage rate of 40% and a non-coverage rate of 29.3%. The overall prognosis for elderly patients who experienced a mild or asymptomatic SARS-CoV-2 Omicron infection at the mobile field hospital was favorable, although the vaccination rate in general was not high. By effectively managing underlying health conditions, the duration of their hospital stay in the mobile field hospital was reduced.

Trends and disparities in prevalence of cardiometabolic diseases by food security status in the United States

BackgroundPrevious studies have demonstrated the association between food security and cardiometabolic diseases (CMDs), yet none have investigated trends in prevalence of CMDs by food security status in the United States (US).MethodsSerial cross-sectional analysis of the US nationally representative data from National Health and Nutrition Examination Survey (1999–2018) was conducted among adults aged 20 years or older. Food security status was defined by the US Household Food Security Survey Module (full, marginal, low, and very low food security). We estimated the age-adjusted prevalence of CMDs including obesity, hypertension, diabetes, and coronary heart disease by food security status. Racial and ethnic disparities in age-adjusted prevalence of CMDs by food security status were also assessed.ResultsA total of 49,738 participants were included in this analysis (weighted mean age 47.3 years; 51.3% women). From 1999 to 2018, the age-adjusted prevalence of CMDs was lower in full food secure group as compared with other groups. For example, trends in hypertension decreased from 49.7% (47.5-51.8%) to 45.9% (43.8-48.0%) (P-trend = 0.002) among the full and from 54.2% (49.9-58.5%) to 49.7% (46.8-52.6%) (P-trend = 0.02) among the marginal but remained stable among the low at 49.7% (47.9-51.6%) and among the very low at 51.1% (48.9-53.3%) (P-interaction = 0.02). Prevalence of diabetes increased from 8.85% (8.15-9.60%) to 12.2% (11.1-13.5%) among the full (P-trend < 0.001), from 16.5% (13.2-20.4%) to 20.9% (18.6-23.5%) (P-trend = 0.045) among the marginal and from 14.6% (11.1-19.0%) to 20.9% (18.8-23.3%) (P-trend = 0.001) among the low but remained stable at 18.8% (17.0-20.9) among the very low (P-trend = 0.35) (P-interaction = 0.03). Racial and ethnic differences in prevalence of CMD by food security status were observed. For example, among individuals with full food secure status, the prevalence of diabetes was 9.08% (95% CI, 8.60-9.59%) for non-Hispanic whites, 17.3% (95% CI, 16.4-18.2%) for non-Hispanic blacks, 16.1% (95% CI, 15.0-17.4%) for Hispanics and 14.9% (95% CI, 13.3-16.7%) for others.Conclusions and relevancePrevalence of CMDs was greatest among those experiencing food insecurity, and food insecurity disproportionately affected racial/ethnic minorities. Disparities in CMD prevalence by food security status persisted or worsened, especially among racial/ethnic minorities.
