ABSTRACT

BACKGROUND: Complementary and alternative medicine (CAM) has played a critical role in ensuring universal access to basic health care services around the world. In Bangladesh, conventional medicine is a common approach for health care practices, yet, due to Bangladesh’s high out-of-pocket payment, millions of people utilise CAM-based healthcare services for illnesses. In Bangladesh, there is a scarcity of data on how CAM is perceived and utilised. The goal of this study was to determine the proportion and correlates of the utilisation of CAM among patients visiting a tertiary level hospital, in Bangladesh.

METHODS: A cross-sectional survey involving 1,183 patients who received health care from a hospital in Bangladesh was interviewed for this study. The associated factors on utilising CAM were identified using multivariable logistic regression analysis.

RESULTS: Thirty-three percent of patients utilised CAM exclusively to treat their illnesses, whereas the rest utilised conventional medicine before CAM. Young adult patients aged 26 to 45 years (AOR = 6.26, 95% CI:3.24-12.07), patients without education (AOR = 2.99, 1.81-4.93), and married patients (AOR = 1.79, 1.08-2.97) were the most likely to be only CAM users. The most common reasons for using CAM were belief in its effectiveness, less adverse effects, affordability and lower costs.

CONCLUSION: In Bangladesh, CAM plays a significant role in health care delivery, with high-levels of patient satisfaction and health benefits. Patients who are older and have a higher level of education are more hesitant to use CAM for their illness, yet CAM has the potential to play a significant role in reducing hospitalisation by providing high reliability and low costs.

ABSTRACT

BACKGROUND: Minimally invasive aortic surgery is growing in popularity among surgeons. Although many clinical reports have proven both the safety and efficacy from a surgical point of view, there are few data regarding its impact on patients’ quality of life and whether there is a difference between ministernotomy and minithoracotomy from the patient perspective.

METHODS: This prospective, questionnaire-based, nonrandomized study included 189 patients who underwent aortic valve replacement via a minimally invasive incision between May 2014 and December 2020 and completed at least 1 year of follow-up. The study uses the RAND SF 36-Item Health Survey 1.0 to assess and compare health-related quality of life between ministernotomy and minithoracotomy.

RESULTS: There was a statistically significant improvement in the minithoracotomy group with regard to physical functioning, role limitation due to a physical problem, and social functioning (79.69 ± 20.72, 75.28 ± 26.52, 87.91 ± 16.98) compared to the ministernotomy group (70.31 ± 22.88, 58.59 ± 31.17, 66.15 ± 27.32) with p values (0.0036, 0.0001, < 0.0001), respectively.

CONCLUSIONS: Both minimally invasive aortic valve incisions positively impacted patient quality of life. The minithoracotomy incision showed significant improvements in physical capacity and successful patient re-engagement in daily physical and social activities. This, in turn, positively improved their general health status compared to the 1-year preoperative status.

TRIAL REGISTRATION: This study was approved by the Research Ethics Committee (REC) at the Faculty of Medicine, Ain Shams University, under the number code (FWA 000017585, FAMSU R 91 /2021).

ABSTRACT

BACKGROUND: Diagnostic errors constitute an important medical safety problem that needs improvement, and their frequency and severity are high in emergency room settings. Previous studies have suggested that diagnostic errors occur in 0.6-12% of first-time patients in the emergency room and that one or more cognitive factors are involved in 96% of these cases. This study aimed to identify the types of cognitive biases experienced by physicians in emergency rooms in Japan.

METHODS: We conducted a questionnaire survey using Nikkei Medical Online (Internet) from January 21 to January 31, 2019. Of the 159,519 physicians registered with Nikkei Medical Online when the survey was administered, those who volunteered their most memorable diagnostic error cases in the emergency room participated in the study. EZR was used for the statistical analyses.

RESULTS: A total of 387 physicians were included. The most common cognitive biases were overconfidence (22.5%), confirmation (21.2%), availability (12.4%), and anchoring (11.4%). Of the error cases, the top five most common initial diagnoses were upper gastrointestinal disease (22.7%), trauma (14.7%), cardiovascular disease (10.9%), respiratory disease (7.5%), and primary headache (6.5%). The corresponding final diagnoses for these errors were intestinal obstruction or peritonitis (27.3%), overlooked traumas (47.4%), other cardiovascular diseases (66.7%), cardiovascular disease (41.4%), and stroke (80%), respectively.

CONCLUSIONS: A comparison of the initial and final diagnoses of cases with diagnostic errors shows that there were more cases with diagnostic errors caused by overlooking another disease in the same organ or a disease in a closely related organ.

ABSTRACT

BACKGROUND: Postpartum depression is a common condition in the pregnancy and postpartum cycle. The development of this condition is multifactorial and can be influenced by previous traumas. This study sought to verify whether there is an association between having been exposed to mistreatment during childbirth and presenting symptoms suggestive of postpartum depression.

METHODS: This is a cross-sectional study, with the inclusion of 287 women without complications in childbirth, randomly selected from two maternity hospitals of Porto Alegre, southern Brazil, in 2016. Four weeks after delivery, the postpartum women answered a face-to-face interview about socioeconomic aspects, obstetric history, health history, and childbirth experience (practices and interventions applied) and completed the Edinburgh Postnatal Depression Scale (EPDS). From the perception of women regarding the practices performed in the context of childbirth care, a composite variable was created, using item response theory, to measure the level of mistreatment during childbirth. The items that made up this variable were: absence of a companion during delivery, feeling insecure and not welcome, lack of privacy, lack of skin-to-skin contact after delivery, not having understood the information shared with them, and not having felt comfortable to ask questions and make decisions about their care. To define symptoms suggestive of postpartum depression, reflecting on increased probability of this condition, the EPDS score was set at ≥ 8. Poisson Regression with robust variance estimation was used for modeling.

RESULTS: Women who experienced mistreatment during childbirth had a higher prevalence of symptoms suggestive of postpartum depression (PR 1.55 95% CI 1.07-2.25), as well as those with a history of mental health problems (PR 1.69 95% CI 1.16-2.47), while higher socioeconomic status (A and B) had an inverse association (PR 0.53 95% CI 0.33-0.83).

CONCLUSIONS: Symptoms suggestive of postpartum depression seem to be more prevalent in women who have suffered mistreatment during childbirth, of low socioeconomic status, and with a history of mental health problems. Thus, qualifying care for women during pregnancy, childbirth and postpartum and reducing social inequalities are challenges to be faced in order to eliminate mistreatment during childbirth and reduce the occurrence of postpartum depression.

ABSTRACT

Only a few meta-analyses evaluated the effect of finerenone on cardiovascular events in type 2 diabetes mellitus (T2DM) with chronic kidney disease (CKD). The main aim of this meta-analysis was to gain more reliable assessments of the efficacy and safety of finerenone for prevention of cardiovascular events in diabetic kidney disease. We searched for finerenone in the treatment of diabetic kidney disease from database (PubMed, Embase and ClinicalTrials.gov) until December 30, 2021. Relative risks (RRs) with 95% confidence intervals (CIs) calculated by the Mantel-Haenszel random-effects model were used as summary statistics for the categorical data. We included four studies that met the inclusion criteria with 13,943 participants. The finerenone group demonstrated a great benefit in reducing the incidence of major adverse cardiac events (MACEs) (RR: 0.88; 95% CI 0.80 – 0.96; P = 0.003), all-cause mortality (RR: 0.89; 95% CI 0.80 – 0.99; P = 0.04), myocardial infarction (RR: 0.79; 95% CI 0.67 – 0.92; P = 0.003) and new-onset hypertension (RR: 0.71; 95% CI 0.62 – 0.81; P < 0.00001). No difference was found in adverse events between the finerenone and placebo groups (RR: 1.00; 95% CI [0.98, 1.01], P = 0.59), whereas, a higher risk of hyperkalemia was observed in the finerenone group than in the placebo group (RR = 2.04, 95% CI 1.80 – 2.32; P < 0.00001). Besides, cerebrovascular events and new-onset atrial fibrillation did not increase in patients taking finerenone. Overall, finerenone treatment showed a great benefit of reducing the risk of MACEs, all-cause mortality, myocardial infarction, and new-onset hypertension events in patients with T2DM and CKD.

ABSTRACT

Anatomical Therapeutic Chemical (ATC) classification for compounds/drugs plays an important role in drug development and basic research. However, previous methods depend on interactions extracted from STITCH dataset which may make it depend on lab experiments. We present a pilot study to explore the possibility of conducting the ATC prediction solely based on the molecular structures. The motivation is to eliminate the reliance on the costly lab experiments so that the characteristics of a drug can be pre-assessed for better decision-making and effort-saving before the actual development. To this end, we construct a new benchmark consisting of 4545 compounds which is with larger scale than the one used in previous study. A light-weight prediction model is proposed. The model is with better explainability in the sense that it is consists of a straightforward tokenization that extracts and embeds statistically and physicochemically meaningful tokens, and a deep network backed by a set of pyramid kernels to capture multi-resolution chemical structural characteristics. Its efficacy has been validated in the experiments where it outperforms the state-of-the-art methods by 15.53% in accuracy and by 69.66% in terms of efficiency. We make the benchmark dataset, source code and web server open to ease the reproduction of this study.

ABSTRACT

Nanoparticle (NP) internalization by cells is complex, highly heterogeneous, and fundamentally important for nanomedicine. We report powerful probabilistic statistics from single-cell data on quantitative NP uptake of PEG-coated transferrin receptor-targeted gold NPs for cancer-derived and fibroblast cells according to their cell size, receptor expression, and receptor density. The smaller cancer cells had a greater receptor density and more efficient uptake of targeted NPs. However, simply due to fibroblasts being larger with more receptors, they exhibited greater NP uptake. While highly heterogeneous, targeted NP uptake strongly correlated with receptor expression. When uptake was normalized to cell size, no correlation existed. Consequently, skewed population distributions in cell sizes explain the distribution in NP uptake. Furthermore, exposure to the transferrin receptor-targeted NPs alters the fibroblast size and receptor expression, suggesting that the receptor-targeted NPs may interfere with the metabolic flux and nutrient exchange, which could assist in explaining the altered regulation of cells exposed to nanoparticles.

ABSTRACT

PURPOSE: Hormone receptor-positive (HR+) human epidermal growth factor receptor 2-negative (HER2-) endocrine-resistant metastatic breast cancer is treated with sequential single-agent chemotherapy with poor outcomes. Sacituzumab govitecan (SG) is a first-in-class antibody-drug conjugate with an SN-38 payload targeting trophoblast cell-surface antigen 2, an epithelial antigen expressed in breast cancer.

METHODS: In this global, randomized, phase III study, SG was compared with physician’s choice chemotherapy (eribulin, vinorelbine, capecitabine, or gemcitabine) in endocrine-resistant, chemotherapy-treated HR+/HER2- locally recurrent inoperable or metastatic breast cancer. The primary end point was progression-free survival (PFS) by blinded independent central review.

RESULTS: Patients were randomly assigned to receive SG (n = 272) or chemotherapy (n = 271). The median age was 56 years, 95% had visceral metastases, and 99% had a prior cyclin-dependent kinase 4/6 inhibitor, with three median lines of chemotherapy for advanced disease. Primary end point was met with a 34% reduction in risk of progression or death (hazard ratio, 0.66 [95% CI, 0.53 to 0.83; P = .0003]). The median PFS was 5.5 months (95% CI, 4.2 to 7.0) with SG and 4.0 months (95% CI, 3.1 to 4.4) with chemotherapy; the PFS at 6 and 12 months was 46% (95% CI, 39 to 53) v 30% (95% CI, 24 to 37) and 21% (95% CI, 15 to 28) v 7% (95% CI, 3 to 14), respectively. Median overall survival (first planned interim analysis) was not yet mature (hazard ratio, 0.84; P = .14). Key grade ≥ 3 treatment-related adverse events (SG v chemotherapy) were neutropenia (51% v 38%) and diarrhea (9% v 1%).

CONCLUSION: SG demonstrated statistically significant PFS benefit over chemotherapy, with a manageable safety profile in patients with heavily pretreated, endocrine-resistant HR+/HER2- advanced breast cancer and limited treatment options.

ABSTRACT

OBJECTIVE: Hypertension is one of the most important factors for cardiovascular disease. It has been repeatedly proposed as a prognostic factor of severe COVID-19 and has been included in clinical risk scores to predict the occurrence of critical illness in ospitalised with COVID-19. Also, it has been postulated the relation between antihypertensive drugs and the severity of COVID-19. The aims of our study were to analyze whether hypertension and antihypertensive treatment represent an independent risk factor for death or intensive care unit admission in patients with SARS-COV2.

DESIGN AND METHOD: Observational, retrospective, single-center cohort study of all patients admitted to Hospital Virgen Macarena diagnosed with COVID-19 between the months of March and December 2020. A bivariate analysis was performed using Pearson’s chi-square.

RESULTS: 608 patients required admission for COVID-19. A total of 83.7% were hypertensive, specifically 75.9% were under antihypertensive treatment (35.7% with only 1 drug, 29.9% were taking two drugs, 9% with three drugs, and 1.3% with 4 drugs). 26.2% were treated with an ACEI, 24.8% with ARA-II, 16.8% with calcium-antagonists, 30.9% with diuretics, 21.2% with beta-blockers, 0, 5% with alpha-blockers). Hypertension did not show a statistically significant relationship with mortality (p = 0.34), increase in mortality and ICU admissions. Neither treatment with ACEI (p = 0.4), ARB-II (p = 0.45), calcium antagonists (p = 0.53), diuretics (p = 0.68), alpha blockers (p = 0.07) demonstrated relation with those items. Surprisingly, beta-blockers increased the mortality in patients with SARS-COV2 (p = 0.048). Probably this results can be explained as these drugs were indicated for rate control in patients with atrial fibrillation (p = 0.006). The number of antihypertensive drugs used also did not show a statistically significant relationship with an increase in mortality (p = 0.978).

CONCLUSIONS: Hypertension is a highly prevalent pathology in patients ospitalised with COVID-19 infection. However, high blood pressure was not associated with a higher risk for mortality in patients with SARS-COV-2, neither the type or the number of antihypertensive drug used. Only beta-blockers alter outcomes in hypertensive patients with COVID-19, as they were associated with more deaths.

ABSTRACT

OBJECTIVE: The Covid-19 pandemic necessitated a decrease in non-Covid-19 related diagnostic and therapeutic procedures in many countries. We explored the impact on hypertension care in the Excellence Center (EC) network of the European Society of Hypertension.

DESIGN AND METHOD: We conducted an electronic survey regarding 6 key procedures in hypertension care among our ECs.

RESULTS: Overall, 54 ECs from 18 European and 3 non-European countries participated. From 2019 to 2020, there was a significant decrease in the median number per center of ambulatory blood pressure monitorings (ABPMs; 544 vs 289), duplex ultrasound investigations of renal arteries (DUS RA; 88.5 vs 55), computed tomographic investigations of renal arteries (CT RA; 66 vs 19.5), percutaneous renal artery angioplasties (PTA RA; 5 vs 1), laboratory tests for catecholamines (2019: 116 vs 67.5) and for ennin/aldosterone (146 vs 83.5). All comparisons were statistically significant with p < 0.001, respectively (Figure). While the reduction in all diagnostic and therapeutic procedures was observed in all 3-months period comparisons between 2019 and 2020, the most profound decrease occurred from April to June 2020, which was the period of the first wave and the first lockdown in most countries. In this period, as compared to 2019, the median reduction in 2020 was 50.7% (ABPM), 47.1% (DUS RA), 50% (CT RA), 57.1% (PTA RA), 46.9% (catecholamines) and 41% (ennin/aldosterone), respectively. Based on Friedman test, overall differences in reduction between 3 months time intervals were statistically highly significant.

CONCLUSIONS: Diagnostic and therapeutic procedures related to hypertension were dramatically reduced during the first year of the Covid-19 pandemic, with the largest reduction during the first lockdown. The long-term consequences regarding blood pressure control and, ultimately, cardiovascular events remain to be investigated.
