Prevalence of unqualified sources of antimalarial drug prescription for children under the age of five: A study in 19 low- and middle-income countries.

BACKGROUND: Antimalarial drug resistance poses a severe danger to global health. In Low- and Middle-Income Countries (LMICs), there is a lack of reliable information on antimalarial prescriptions for recent malarial fever in children under five. Our study aims to determine the prevalence of unqualified sources of antimalarial drug prescription for children under the age of five in 19 low- and middle-income countries. METHODS: We performed a cross-sectional study of the Malaria Indicator Survey (MIS) datasets (n = 106265) across 19 LMICs. The recent MIS datasets were used, and the study only included children under five who had taken an antimalarial drug for a recent malarial fever. The outcome variable was classified into two distinct categories: those who had taken antimalarial drugs for malarial fever from qualified sources and those who did not. FINDINGS: Among LMICs, we found that 87.1% of children under five received an antimalarial prescription from unqualified sources who had recently experienced malarial fever. In several LMICs (Tanzania, Nigeria, and Ghana), a substantial portion of recent antimalarial prescriptions for malaria was taken from unqualified sources (about 60%). Some LMICs (Guinea (31.8%), Mali (31.3%), Nigeria (20.4%), Kenya (2.6%), and Senegal (2.7%)) had low rates of antimalarial drug consumption even though children under five received a high percentage of antimalarial prescriptions from qualified sources for a recent malarial fever. Living in rural areas, having mothers with higher education, and having parents with more wealth were frequently taken antimalarial from qualified sources for recent malarial fever in children under five across the LMICs. INTERPRETATION: The study draws attention to the importance of national and local level preventative strategies across the LMICs to restrict antimalarial drug consumption. This is because antimalarial prescriptions from unqualified sources for recent malarial fever in children under five were shockingly high in most LMICs and had high rates of unqualified prescriptions in certain other LMICs.

Percutaneous coronary intervention before transcatheter aortic valve implantation: A propensity score matched analysis.

BACKGROUND: The role of percutaneous coronary intervention (PCI) in patients with stable coronary artery disease (CAD) who subsequently undergo transcatheter aortic valve replacement (TAVR) remains uncertain. Therefore, we conducted this study to assess the association of PCI before TAVR with mortality and cardiovascular outcomes. METHODS: We used the TriNetX database (Jan 2012 - Aug 2022) and grouped patients into PCI (3 months or less) before TAVR and no PCI. We performed propensity score matched (PSM) analyses for outcomes at 30 days and 1 year. RESULTS: Of 17,120 patients undergoing TAVR, 2322 (14 %) had PCI, and 14,798 (86 %) did not have PCI before TAVR. In the PSM cohort (2026 patients in each group), PCI was not associated with lower all-cause mortality at 30 days (HR: 1.25, 95 % CI: 0.82-1.90) or 1 year (HR: 1.02, 95 % CI: 0.83-1.24). Frequency of repeat PCI after TAVR was low in both no PCI vs. PCI (2.4 % vs. 1.2 %) at 1 year; PCI was associated with a lower rate of repeat PCI (HR: 0.49, 95 % CI: 0.30-0.80). Sensitivity analysis revealed an E-value of 3.5 for repeat PCI (E-value for lower CI for HR: 1.81). PCI was not linked to reductions in MI, heart failure exacerbation, all-cause hospitalization, major bleeding, or permanent pacemaker/implantable cardioverter defibrillator. CONCLUSION: This analysis showed that PCI prior to TAVR was not associated with improvement in all-cause mortality. However, PCI was associated with a reduced rate of repeat PCI at 1 year.

Examining the disparities of anti-malarial drug consumption among children under the age of five: a study of 5 malaria-endemic countries.

BACKGROUND: Malaria is one of the most prominent illnesses affecting children, ranking as one of the key development concerns for many low- and middle-income countries (LMICs). There is not much information available on the use of anti-malarial drugs in LMICs in children under five. The study aimed to investigate disparities in anti-malarial drug consumption for malaria among children under the age of five in LMICs. METHODS: This study used recent available cross-sectional data from the Malaria Indicator Survey (MIS) datasets across five LMICs (Guinea, Kenya, Mali, Nigeria, and Sierra Leone), which covered a portion of sub-Saharan Africa. The study was carried out between January 2, 2023, and April 15, 2023, and included children under the age of five who had taken an anti-malarial drug for malaria 2 weeks before the survey date. The outcome variable was anti-malarial drug consumption, which was classified into two groups: those who had taken anti-malarial drugs and those who had not. RESULTS: In the study of LMICs, 32,397 children under five were observed, and among them, 44.1% had received anti-malarial drugs. Of the five LMICs, Kenya had the lowest (9.2%) and Mali had the highest (70.5%) percentages of anti-malarial drug consumption. Children under five with malaria are more likely to receive anti-malarial drugs if they are over 1 year old, live in rural areas, have mothers with higher education levels, and come from wealthier families. CONCLUSION: The study emphasizes the importance of developing universal coverage strategies for anti-malarial drug consumption at both the national and local levels. The study also recommends that improving availability and access to anti-malarial drugs may be necessary, as the consumption of these drugs for treating malaria in children under the age of five is shockingly low in some LMICs.

A rare presentation of idiopathic small bowel diaphragm disease - A case report.

INTRODUCTION: Diaphragm disease, typically associated with long-term non-steroidal anti-inflammatory drug (NSAID) use, manifests as diaphragm-like small bowel strictures, often resulting in bowel obstruction. CASE DESCRIPTION: A 75-year-old male presented with features of recurrent subacute intestinal obstruction, later diagnosed with multiple small bowel strictures via CT imaging. Surgical intervention, including resection and anastomosis, was performed to alleviate the obstruction. Histopathological examination of the resected specimen confirmed diaphragm disease, challenging its traditional association with NSAID use. DISCUSSION: Diaphragm disease, characterized by mucosal and submucosal diaphragm-like strictures, is typically attributed to NSAID usage. However, this case underscores the possibility of diaphragm disease in the absence of NSAID exposure. Pathological findings supported the presence of diaphragm-like strictures, despite the patient's denial of NSAID use. CONCLUSION: This case emphasizes the importance of considering diaphragm disease as a differential diagnosis in patients with intermittent bowel obstruction, even in the absence of NSAID history.

Association of serum beta hCG levels in women with palpable malignant breast lesions.

This study aims to determine whether serum Beta hCG can be used as a tumour marker in Breast malignancies. The objective of this study is to evaluate the serum Beta hCG in various stages of breast carcinoma and to correlate its level with disease severity and prognosis. Cross sectional analytical study of assessing serum Beta hCG in 200 patients with palpable breast malignancies at hospitals in urban Mangalore, India. In our study there was No increase in serum Beta hCG, in women with breast malignancies, but there was a pattern amongst the negative results. A Beta hCG of < 5mIU/mL is taken as negative, but in our study of 200 individuals, a mean value of 2mIU/mL was used as differentiation between low and high risk individuals. With our study we tried to correlate the value of Beta hCG with malignant breast lesions, and even though women with such lesions did not have a value of > 5mIU/mL, we found substantial evidence that women who had a value of > 2mIU/mL had a more advanced disease, be it in terms of staging, and comparing it with markers like ki67. A direct correlation between Beta hCG and severity of the disease in terms of staging was proved, hereby directly affecting the outcome of patients. Higher the level of Beta hCG, graver the prognosis. Even though Beta hCG cannot be used as tumour marker, it can be used to prognosticate the severity in women with palpable breast malignancies.

Antibiotic prescription from qualified sources for children with fever/cough: cross-sectional study from 59 low- and middle-income countries.

Background: Children in low and middle-income countries (LMICs) receive a staggering number of antibiotic prescriptions, many of which are inappropriate. We aimed to explore the proportion of antibiotic prescriptions from qualified sources of children under five who had a fever/cough in the two weeks prior to the survey in LMICs. Methods: We used data from cross-sectional studies of the latest Demographic and Health Survey (DHS) datasets (n = 43,166) in 59 LMICs covering Sub-Saharan Africa, North Africa-West Asia-Europe, Central Asia, South & Southeast Asia, Oceania, and Latin America & the Caribbean regions. The study was conducted from March 2, 2020 to October 15, 2022. We only included the latest available surveys by country, and children under five who had taken antibiotics for fever/cough were included in the study. Finally, the outcome variable was classified into two distinct categories: those who had taken antibiotics from qualified sources and those who did not. Findings: About three in four children (74.0%) received antibiotics from qualified sources. Tanzania (22.4%) and Malawi (99.9%) had the lowest and highest percentages of antibiotic prescriptions by qualified sources, respectively. Oceania had the highest percentage of qualified antibiotic prescriptions with 88.9% and Central Asia had the lowest percentage with 56.3%. Interpretation: As unqualified sources of antibiotics for fever/cough in children under five were alarmingly high in some of the LMICs, the study emphasises the importance of nationwide efforts to regulate antibiotics prescriptions. Funding: None.

Tricuspid Regurgitation Related Mortality in United States, 1999-2019.

Tricuspid regurgitation (TR) is being increasingly recognized in patient population. We aimed to investigate the long-term mortality due to TR in the United States (US) and demographic disparities in TR-related mortality using "Multiple Cause of Death data" via the Centers for Disease Control and Prevention Wide-Ranging On-line Data for Epidemiologic Research datasets, 1999 to 2019. The results from present analysis suggest that TR related deaths in the US may have increased over the last 20 years. This trend may justify greater focus on timely diagnosis and management of TR.

Extensive Painless Aortic Dissection in a Patient With Breast Cancer.

The Year in Cardio-oncology 2022.

Cardiovascular disease and cancer are the leading causes of death worldwide. With advent of novel and improved cancer therapies, a growing population of cancer patients with cardiac complications is seen. Taking this into consideration, the clinical studies have also shifted their focus from the study of a single disease to the interdisciplinary study of oncology and cardiology. This current review article provides a comprehensive review of all major articles and guidelines from the year 2021-2022 in the field of cardio-oncology.

Trigger related outcomes of takotsubo syndrome in a cancer population.

Background: Takotsubo syndrome (TTS) occurs more frequently in cancer patients than in the general population, but the effect of specific TTS triggers on outcomes in cancer patients is not well studied. Objectives: The study sought to determine whether triggering event (chemotherapy, immune-modulators vs. procedural or emotional stress) modifies outcomes in a cancer patient population with TTS. Methods: All cancer patients presenting with acute coronary syndrome (ACS) between December 2008 and December 2020 at our institution were enrolled in the catheterization laboratory registry. Demographic and clinical data of the identified patients with TTS were retrospective collected and further classified according to the TTS trigger. The groups were compared with regards to major adverse cardiac events, overall survival and recovery of left ventricular ejection fraction (LVEF) and global longitudinal strain (GLS) after TTS presentation. Results: Eighty one of the 373 cancer patients who presented with ACS met the Mayo criteria for TTS. The triggering event was determined to be "cancer specific triggers" (use of chemotherapy in 23, immunomodulators use in 7, and radiation in 4), and "traditional triggers" (medical triggers 22, and procedural 18 and emotional stress in 7). Of the 81 patients, 47 died, all from cancer-related causes (no cardiovascular mortality). Median survival was 11.9 months. Immunomodulator (IM) related TTS and radiation related TTS were associated with higher mortality during the follow-up. Patients with medical triggers showed the least recovery in LVEF and GLS while patients with emotional and chemotherapy triggers, showed the most improvement in LVEF and GLS, respectively. Conclusion: Cancer patients presenting with ACS picture have a high prevalence of TTS due to presence of traditional and cancer specific triggers. Survival and improvement in left ventricular systolic function seem to be related to the initial trigger for TTS.

Percutaneous coronary intervention in patients with cancer using bare metal stents compared to drug-eluting stents.

Background: Management of coronary artery disease (CAD) is unique and challenging in cancer patients. However, little is known about the outcomes of using BMS or DES in these patients. This study aimed to compare the outcomes of percutaneous coronary intervention (PCI) in cancer patients who were treated with bare metal stents (BMS) vs. drug-eluting stents (DES). Methods: We identified cancer patients who underwent PCI using BMS or DES between 2013 and 2020. Outcomes of interest were overall survival (OS) and the number of revascularizations. The Kaplan-Meier method was used to estimate the survival probability. Multivariate Cox regression models were utilized to compare OS between BMS and DES. Results: We included 346 cancer patients who underwent PCI with a median follow-up of 34.1 months (95% CI, 28.4-38.7). Among these, 42 patients were treated with BMS (12.1%) and 304 with DES (87.9%). Age and gender were similar between the BMS and DES groups (p = 0.09 and 0.93, respectively). DES use was more frequent in the white race, while black patients had more BMS (p = 0.03). The use of DES was more common in patients with NSTEMI (p = 0.03). The median survival was 46 months (95% CI, 34-66). There was no significant difference in the number of revascularizations between the BMS and DES groups (p = 0.43). There was no significant difference in OS between the BMS and DES groups in multivariate analysis (p = 0.26). In addition, independent predictors for worse survival included age > 65 years, BMI ≤ 25 g/m2, hemoglobin level ≤ 12 g/dL, and initial presentation with NSTEMI. Conclusions: In our study, several revascularizations and survival were similar between cancer patients with CAD treated with BMS and DES. This finding suggests that DES use is not associated with an increased risk for stent thrombosis, and as cancer survival improves, there may be a more significant role for DES.

Determinants of change in code status among patients with cardiopulmonary arrest admitted to the intensive care unit.

BACKGROUND: Patients with cardiopulmonary arrest often have a poor prognosis, prompting discussion with families about code status. The impact of socioeconomic factors, demographics, medical comorbidities and medical interventions on code status changes is not well understood. METHODS: This retrospective study included adult patients presenting with cardiac arrest to the intensive care unit of a hospital group between 5/1/2010-5/1/2020. We extracted chart data on socioeconomic factors, demographics, and medical comorbidities. RESULTS: We identified 1,254 patients, of which 57.5% were males. Age was different across the groups with (61.2 ± 15.5 years) and without (61.2 ± 15.5 years) code status change (p= <0.0001). Code status was changed in 583 patients (46.5%). Among patients with code status change, the highest prevalence was White patients (34.8%), followed by African Americans (30.9%), and Hispanics (25.4%). Compared to patients who did not have a code status change, those with a change in code status were older (66.7 ± 14.8 years vs 61.2 ± 15.5 years). They were also more likely to receive vasopressor/inotropic support (74.6% vs 58.5%), and broad-spectrum antibiotics (70.3% vs 57.7%). Insurance status, ethnicity, religion, education, and salary did not lead to statistically significant changes in code status. CONCLUSIONS: In patients with cardiopulmonary arrest, code status change was more likely to be influenced by the presence of medical comorbidities and medical interventions during hospitalization rather than by socioeconomic factors.

Left sided Amyand hernia - A case report.

INTRODUCTION: Amyand hernia is a clinical condition wherein content of the inguinal hernial sac is formed by the vermiform appendix. CASE PRESENTATION: 1 year 3-month-old male child presented to our OPD with an irreducible left inguinal hernia for which he was taken up for an emergency herniotomy. The terminal ileum, caecum and appendix were found to be the contents of the hernial sac. DISCUSSION: As the appendix is anatomically located on the right, Amyand hernia more commonly occurs on the right, however its occurrence on the left, is a rare event and is usually associated with congenital anomalies like Intestinal malrotation, Situs inversus and mobile caecum. CONCLUSION: Amyand hernia presenting on the left is extremely rare and high index of clinical suspicion is required to manage such patients. We report one such rare case of a Left sided Amyand hernia in a young child.

Amiodarone Related Skin Toxicity -The Blue Man Syndrome; a Case Report and Review of Literature.

Amiodarone induced blue-gray syndrome is a rare condition. It develops over years of use of amiodarone and can lead to discontinuation of the drug. It tends to develop over the sun exposed areas of the body typically involving the face and neck. Published medical literature is scarce with regard to the pathogenesis, clinical implications and management of this potential association. We chronicle here the case of a patient with amiodarone induced blue-grey discoloration of skin from our clinical experience. Furthermore, a systematic literature search of the medical databases PubMed and Google Scholar was conducted. A total of 9 cases fulfilled the inclusion criteria. The data on patients' characteristics, epidemiology, clinical features, comorbid conditions, diagnosis, clinical course and outcome were analyzed. The present review outlines our current understanding of the epidemiology and risk factors for amiodarone induced-blue man syndrome, the pathophysiology of this condition and currently available management options.

Predictors of Recurrence and Survival in Cancer Patients With Pericardial Effusion Requiring Pericardiocentesis.

Aim: This study investigated the factors predicting survival and the recurrence of pericardial effusion (PE) requiring pericardiocentesis (PCC) in patients with cancer. Materials and Methods: We analyzed the data of patients who underwent PCC for large PEs from 2010 to 2020 at The University of Texas MD Anderson Cancer Center. The time to the first recurrent PE requiring PCC was the interval from the index PCC with pericardial drain placement to first recurrent PE requiring drainage (either repeated PCC or a pericardial window). Univariate and multivariate Fine-Gray models accounting for the competing risk of death were used to identify predictors of recurrent PE requiring drainage. Cox regression models were used to identify predictors of death. Results: The study cohort included 418 patients with index PCC and pericardial drain placement, of whom 65 (16%) had recurrent PEs requiring drainage. The cumulative incidences of recurrent PE requiring drainage at 12 and 60 months were 15.0% and 15.6%, respectively. Younger age, anti-inflammatory medication use, and solid tumors were associated with an increased risk of recurrence of PE requiring drainage, and that echocardiographic evidence of tamponade at presentation and receipt of immunotherapy were associated with a decreased risk of recurrence. Factors predicting poor survival included older age, malignant effusion on cytology, non-use of anti-inflammatory agents, non-lymphoma cancers and primary lung cancer. Conclusion: Among cancer patients with large PEs requiring drainage, young patients with solid tumors were more likely to experience recurrence, while elderly patients and those with lung cancer, malignant PE cytology, and non-use of anti-inflammatory agents showed worse survival.

Applications of indocyanine green in surgery: A single center case series.

Background: Fluorescence imaging using indocyanine green (ICG) has revolutionized commonly performed general surgical procedures by providing superior anatomic imaging and enhancing safety for patients. ICG, when injected, shows a bright green fluorescence when subjected to the near infra-red (NIR) spectrum. Materials and methods: We employed the use of ICG in Laparoscopic cholecystectomy, Intestinal Colorectal Anastomosis and Hernia to assess vascularity of resected ends and bowel viability, Sentinel Lymph node mapping, Vascular surgery to assess amputation stump success and in assessing Flap Vascularity and healing. Results: ICG when administered had successfully shown bright green fluorescence in different cases thereby aiding in surgical procedures. Conclusion: Routine intraoperative use of ICG could pave the way for a more objective assessment of different surgical circumstances and thereby reduce personalized barriers to aciurgy. ICG fluorescence therefore seems to be a promising apparatus in standard general surgical procedures minimizing untoward errors and improving patient conformance.

Rare cause of thyroid enlargement: Localized AA amyloid goiter - A case report.

INTRODUCTION: Amyloidosis is extracellular deposition of fibrillary amyloid proteins in various organs. Amyloid infiltration in thyroid is common; however, the occurrence of clinically enlarged thyroid, subsequently leading to goiter, is a rare phenomenon. CASE PRESENTATION: 36 years old female presented to our OPD with multinodular goiter. She subsequently underwent total thyroidectomy. Thyroidectomy specimen revealed amyloid deposition with characteristic congophilia and birefringence. Further evaluation revealed it to be AA amyloidosis. There were no features of systemic amyloidosis. DISCUSSION: Amyloidosis is classified on the type of amyloid protein. Treatment of individual types of amyloidosis is diverse, and hence identification of the protein subtype is paramount. CONCLUSION: AA amyloidosis localized primarily to thyroid is infrequent, as it usually occurs with chronic inflammatory conditions or infections. Currently, there are no guidelines for the treatment of localized AA amyloid goiter. We have evidence demonstrating the successful treatment of such a condition with no recurrence noted.

Double Delayed Enhancement: Concomitant Cardiac Amyloidosis and Acute Coronary Embolism.

Hereditary cardiac amyloidosis (CA) is a relatively rare cause of nonischemic cardiomyopathy. The risk of intracardiac thrombi increases significantly in patients with CA. We report a case of a patient presenting with chest pain and acute myocardial infarction who was subsequently diagnosed with concomitant CA and acute coronary embolism.

Exploiting circadian memory to hasten recovery from circadian misalignment.

Recent years have seen a sustained interest in the development of circadian reentrainment strategies to limit the deleterious effects of jet lag. Due to the dynamical complexity of many circadian models, phase-based model reduction techniques are often an imperative first step in the analysis. However, amplitude coordinates that capture lingering effects (i.e., memory) from past inputs are often neglected. In this work, we focus on these amplitude coordinates using an operational phase and an isostable coordinate framework in the context of the development of jet-lag amelioration strategies. By accounting for the influence of circadian memory, we identify a latent phase shift that can prime one's circadian cycle to reentrain more rapidly to an expected time-zone shift. A subsequent optimal control problem is proposed that balances the trade-off between control effort and the resulting latent phase shift. Data-driven model identification techniques for the inference of necessary reduced order, phase-amplitude-based models are considered in situations where the underlying model equations are unknown, and numerical results are illustrated in both a simple planar model and in a coupled population of circadian oscillators.
