ABSTRACT

OBJECTIVE: We aimed to predict the risk of hypotension due to spinal anesthesia (HSA) by measuring the diameter and area of the inferior vena cava (IVC-D, IVC-A) through ultrasound and pleth variability index (PVI) in patients who underwent endovenous radiofrequency ablation under spinal anesthesia (SA).

METHODS: This cross-sectional, observational, and prospective study was completed with 64 patients. Before SA, PVI IVC-D, and IVC-A were measured. Patients were divided into two groups as hypotension group (Group 1) and patients who did not developed hypotension after SA (Group 2). Shapiro-Wilk normality test and student’s t-test were used for statistical analysis.

RESULTS: The mean PVI of Group 1 was higher than Group 2, whereas the mean IVC-D and IVC-A in Group 2 was significantly higher than Group 1 (p = 0.000, p = 0.000, p = 0.001). Cutoff values for hypotension PVI > 15% and IVC-A ≤ 2.98 mm2 (p = 0.001, p < 0.05).

CONCLUSION: PVI and IVC-D and IVC-A measurements are effective and reliable methods that should be used to predict the risk of developing HSA in patients who will undergo surgery under SA.

ABSTRACT

OBJECTIVE: This study aimed to investigate serum metabolomic biomarkers associated with incident type 2 diabetes mellitus (T2DM) and evaluate their performance in improving T2DM risk prediction.

METHODS: Untargeted proton nuclear magnetic resonance (1H NMR) spectroscopy-based metabolomics analyses were conducted in the Multi-Ethnic Study of Atherosclerosis (MESA; n=3460; discovery cohort) and Rotterdam Study (RS; n=1556; replication cohort). Multivariable cause-specific hazards models were used to analyze the associations between 23,571 serum metabolomic spectral variables and incident T2DM. Replicated metabolites required an FDR-adjusted P<0.01 in MESA, P<0.05 in RS, and consistent direction of association. Pathway and network analyses were conducted to elucidate biological mechanisms underlying T2DM development. Utility of the replicated metabolites in improving T2DM risk prediction was assessed based on the Framingham Diabetes Risk Score. A 2-sample Mendelian randomization was conducted to assess causal associations.

RESULTS: Nineteen metabolites were significantly associated with incident T2DM. Pathway analyses revealed disturbances in aminoacyl-tRNA biosynthesis, metabolism of branched-chain amino acids (BCAAs), glycolysis/gluconeogenesis, and glycerolipid metabolism. Network analyses identified interactions with upstream regulators including p38 MAPK, c-JNK, and mTOR signaling pathways. Adding replicated metabolites to the Framingham Diabetes Risk Score showed modest to moderate improvements in prediction performance in MESA and RS, with Δ c-statistic of 0.05 (95% CI, 0.04-0.07) in MESA and 0.03 (95% CI, 0.01-0.05) in RS. Genetically increased BCAAs and mannose were associated with T2DM.

CONCLUSIONS: 1H NMR measured metabolites involved in aminoacyl-tRNA biosynthesis, BCAA metabolism, glycolysis/gluconeogenesis, and glycerolipid metabolism were significantly associated with incident T2DM and provided modest to moderate predictive utility beyond traditional risk factors.

ABSTRACT

This study aims to provide an investigation of the containment and mitigation strategies encompassing the entirety of the pandemic in Taiwan. This descriptive, observational study used COVID-19 data from Taiwan, Japan, and South Korea, and analysed news releases from the Taiwanese health authority. Statistics provided evidence of outbreak severity through infection and mortality rates, while qualitative results from the document review offered insights on the actions taken by the government chronologically from 2 February 2020 to 31 December 2022. All three countries experienced significant infection peaks in 2022. Taiwan had two distinct peaks, one in late May and another in October. South Korea had a single, high peak in late March, while Japan experienced multiple smaller waves, the biggest wave in August. Similarly, weekly mortality rates peaked in 2022 for all three countries after a surge in their infected cases, with Taiwan (5.15/100 000) and South Korea (4.69/100 000) having higher rates than Japan (1.65/100 000). Results from qualitative analysis showed that Taiwan’s early containment measures might have delayed the epidemic curve, allowing time for better preparation and proactive responses. However, the lack of a clear transition plan and the vulnerability of the elderly population contributed to higher mortality and infection rates. Despite ongoing challenges, Taiwan avoided nationwide lockdowns and relied on targeted restrictions to control transmission of the virus. Results of this article offer the narratives, reflections, and experiences from the case of Taiwan which may potentially present promising opportunities for impact in other settings and for future pandemics.

ABSTRACT

Vitamin D dysregulation can occur in people living with HIV, disrupting calcium homeostasis and bone turnover. We aimed to investigate the potential mechanisms by which vitamin D regulates bone turnover in adolescents living with perinatally-acquired HIV (ALWH) in southern Africa. A pre-planned secondary analysis was performed of baseline data from the VITALITY trial [PACTR20200989766029] which enrolled ALWH (11-19 years) taking antiretroviral therapy for ≥6 months, and recorded socio-demographic, clinical and dietary data. After over-night fasting, vitamin D metabolites [25(OH)D, 1,25(OH)2D, 24,25(OH)2D], intact parathyroid hormone (PTH) and bone turnover markers (BTMs) [CTX and P1NP] were measured. Tandem Mass Spectrometry measured vitamin D metabolites, whilst intact PTH and BTMs were analysed by electrochemiluminescence immunoassay. Stratified by 25(OH)D [<75 vs ≥75 nmol/L], associations between standardized concentrations (β = standard deviations) of vitamin D metabolites, intact PTH and BTMs were assessed using structural equations modelling (SEM) adjusted for age, sex and country (Zimbabwe/Zambia). Among the 842 ALWH enrolled, the median dietary calcium intake was 100 mg [IQR:55-145]. The SEM showed PTH was positively associated [β 0.21, 95%CI: 0.1,0.32] with 1,25(OH)2D, only when 25(OH)D was <75 nmol/L vs ≥75 nmol/L [β 0.23, 95%CI: -0.13,0.59], with evidence of an interaction [β -0.11, 95%CI: -0.20,-0.02]. A positive relationship between 25(OH)D and 24,25(OH)2D was seen irrespective of 25(OH)D concentration. 24,25(OH)2D was inversely related to BTMs, particularly when 25(OH)D was <75 nmol/L [CTX: β -0.15, 95%CI: -0.24,-0.06, and P1NP: β -0.14, 95%CI: -0.22,-0.06]. There was interaction between dietary calcium and 25(OH)D on PTH [β -0.15, 95% CI: -0.22,-0.07] suggesting an interaction between low 25(OH)D and low dietary calcium which increases PTH. In conclusion, associations between 25(OH)D, PTH, 1,25(OH)2D and BTMs in ALWH appear dependent upon 25(OH)D concentrations <75 nmol/L and calcium intake. A novel, potentially causal pathway between 25(OH)D, 24,25(OH)2D and BTMs was seen. Findings enhance understanding of vitamin D metabolism in people living with HIV.

ABSTRACT

BACKGROUND: When research and management of Dupuytren’s disease (DD) shift from symptom relief to preventing contractures, general practitioner (GP) care may become more central to treatment. However, the presentation and course of DD in GP care are underexplored and this has been recognized as a knowledge gap that hinders effective treatment decisions. This study is the first to map the trajectory of DD patients in GP care.

METHODS: Using electronic health records from Dutch general practices in a regional research network, we conducted a registration-based cohort study in a dynamic population. Descriptive statistics detailed patient demographics, number of contacts, and symptoms per contact. The time and number of contacts before diagnosis were also analysed. Sankey diagrams illustrated the relationship between management options and symptoms.

RESULTS: Over a 16-year period, 84% of patients with a DD diagnosis had visited their GP for this reason, with 73% only having one GP contact. The diagnosis was made at first contact for 93% of patients. Initial contacts often reported a lump (57.3%), but this symptom was less frequent in subsequent visits. ‘Daily life impairment’ increased after the first contact. The most common management options were referral to secondary care (37.7%) and watchful waiting (35.1%).

CONCLUSION: The diagnosis and management of DD in GP care are in line with the current guidelines. Less than half of the DD patients were referred to secondary care during follow-up. This may give room for preventive treatment that limits progression. Future studies should focus on the accuracy of diagnosis and the feasibility of effective treatments in GP care.

ABSTRACT

BACKGROUND: Biliary tract cancer (BTC) is an aggressive biliary tract cancer, arising from the bile ducts and gallbladder, with a poor prognosis. The TOPAZ-1 trial of durvalumab plus first-line chemotherapy (gemcitabine plus cisplatin) showed improved survival vs chemotherapy alone. This real-world study aimed to confirm the effectiveness of this regimen.

METHODS: This retrospective, multicenter study included patients with advanced BTC treated with first-line durvalumab plus platinum chemotherapy at the Linkou, Taoyuan, and Tucheng branches of Chang Gung Memorial Hospital as well as at Taipei Veterans General Hospital between August 2021 and June 2023.

RESULTS: Among the 45 patients with advanced biliary tree cancer treated with durvalumab plus cisplatin and gemcitabine as first-line treatment, the objective response rate was 31.1% (14 partial responses). An additional 40% (18 patients) had stable disease. The median progression-free survival was 5.6 months (95%CI, 4.4-6.9) and median overall survival was 15.8 months (95%CI, 7.9-23.8). Responders had significantly longer survival than non-responders (15.8 vs 3.3 months). Although higher durvalumab doses (1000-1500 mg) appeared to have improved efficacy compared to lower doses (<1000 mg), the difference was not statistically significant. On multivariate analysis, poor ECOG performance status (≥2) and a high neutrophil-lymphocyte ratio were independent prognostic factors for shorter overall survival.

CONCLUSION: This real-world study demonstrated the comparable efficacy of durvalumab plus chemotherapy to the TOPAZ-1 trial for patients with advanced BTC and identified prognostic factors. There was a trend toward improved efficacy with higher durvalumab dosing (1000-1500 mg) vs lower dosing, though further research is needed to confirm this relationship.

ABSTRACT

BACKGROUND: Since its introduction, telemedicine for patients with chronic diseases has been studied in various clinical settings. However, there is limited evidence of the effectiveness and medical safety of the nationwide adoption of telemedicine.

OBJECTIVE: This study aimed to analyze the effects of telemedicine on chronic diseases during the COVID-19 pandemic under a temporary telemedicine policy in South Korea using national claims data.

METHODS: Health insurance claims data were extracted over 2 years: 1 year before (from February 24, 2019, to February 23, 2020) and 1 year after the policy was implemented (from February 24, 2020, to February 23, 2021). We included all patients who used telemedicine at least once in the first year after the policy was implemented and compared them with a control group of patients who never used telemedicine. The comparison focused on health care use; the medication possession ratio (MPR); and admission rates to general wards (GWs), emergency departments (EDs), and intensive care units (ICUs) using difference-in-differences analysis. A total of 4 chronic diseases were targeted: hypertension, diabetes mellitus (DM), chronic obstructive pulmonary disease (COPD), and common mental disorders.

RESULTS: A total of 1,773,454 patients with hypertension; 795,869 patients with DM; 37,460 patients with COPD; and 167,084 patients with common mental disorders were analyzed in this study. Patients diagnosed with hypertension or DM showed increased MPRs without an increase in GW, ED, or ICU admission rates during the policy year. Moreover, patients in the DM group who did not use telemedicine had higher rates of ED, GW, and ICU admissions, and patients in the hypertension group had higher rates of GW or ICU admissions after 1 year of policy implementation. This trend was not evident in COPD and common mental disorders.

CONCLUSIONS: The temporary telemedicine policy was effective in increasing medication adherence and reducing admission rates for patients with hypertension and DM; however, the efficacy of the policy was limited for patients with COPD and common mental disorders. Future studies are required to demonstrate the long-term effects of telemedicine policies with various outcome measures reflecting disease characteristics.

ABSTRACT

BACKGROUND: The World Health Organization has set a global strategy to eliminate cervical cancer, emphasizing the need for cervical cancer screening coverage to reach 70%. In response, China has developed an action plan to accelerate the elimination of cervical cancer, with Hubei province implementing China’s first provincial full-coverage screening program using an artificial intelligence (AI) and cloud-based diagnostic system.

OBJECTIVE: This study aimed to evaluate the performance of AI technology in this full-coverage screening program. The evaluation indicators included accessibility, screening efficiency, diagnostic quality, and program cost.

METHODS: Characteristics of 1,704,461 individuals screened from July 2022 to January 2023 were used to analyze accessibility and AI screening efficiency. A random sample of 220 individuals was used for external diagnostic quality control. The costs of different participating screening institutions were assessed.

RESULTS: Cervical cancer screening services were extended to all administrative districts, especially in rural areas. Rural women had the highest participation rate at 67.54% (1,147,839/1,699,591). Approximately 1.7 million individuals were screened, achieving a cumulative coverage of 13.45% in about 6 months. Full-coverage programs could be achieved by AI technology in approximately 1 year, which was 87.5 times more efficient than the manual reading of slides. The sample compliance rate was as high as 99.1%, and compliance rates for positive, negative, and pathology biopsy reviews exceeded 96%. The cost of this program was CN ¥49 (the average exchange rate in 2022 is as follows: US $1=CN ¥6.7261) per person, with the primary screening institution and the third-party testing institute receiving CN ¥19 and ¥27, respectively.

CONCLUSIONS: AI-assisted diagnosis has proven to be accessible, efficient, reliable, and low cost, which could support the implementation of full-coverage screening programs, especially in areas with insufficient health resources. AI technology served as a crucial tool for rapidly and effectively increasing screening coverage, which would accelerate the achievement of the World Health Organization’s goals of eliminating cervical cancer.

ABSTRACT

Importance: Little is known about differences between Black and White women with respect to the prevalence of postpartum mood disorders or symptom presentations.

Objective: To determine the prevalence and characteristics of postpartum major mood disorders in Black and White women at 4-6 weeks after birth.

Methods: This is a secondary analysis of a large-scale study designed to screen women for postpartum depression with the Edinburgh Postnatal Depression Scale (EPDS) and collect symptom data. Data were collected at an urban maternity hospital in an academic setting in Pittsburgh, Pennsylvania. Of the 2,019 women who screened positive and accepted a psychiatric diagnostic interview, 163 and 85 Black women had major depressive and bipolar disorders, respectively, and 508 and 177 White women had major depressive and bipolar disorders, respectively. Those with an EPDS score greater than or equal to 10 were offered a psychiatric assessment (in-person at home or by telephone) with the Structured Clinical Interview for DSM IV using the Structured Interview Guide for the Hamilton Rating Scale for Depression, Atypical Depression Version symptom inventory, a questionnaire related to childhood and adulthood physical and sexual abuse, and the Short Form Survey 12. Participants who self-identified as Black or White were included in this analysis.

Results: Among screen-positive participants, no significant difference in the rate of major depressive disorder (40% Black and 35% White) was observed. However, bipolar disorder significantly differed between Black (19.2%) and White (11.5%) women. Additionally, symptom profiles differed between Black and White participants with major depressive disorder, and a high rate of traumatic experiences was reported by participants with major depression and bipolar disorder in both racial groups.

Conclusion: An understanding of the different presentations of postpartum mood disorders between Black and White women, as well as trauma-informed care, can optimize postpartum health care through supporting advocacy efforts for resource allocation and health care delivery.

ABSTRACT

About 5%-10% of pregnancies in the US are exposed to cannabis with highest use reported during the first trimester. Two recent meta-analyses presented estimates of the risk of birth defects associated with prenatal exposure to cannabis; the larger and more recent meta-analysis pooled data from 18 cohort and 18 case-control studies with a total sample size of >19 million subjects. The meta-analyses found that prenatal exposure to cannabis was associated with a small but statistically significant increased risk of any birth defect (pooled odds ratios [ORs], 1.25-1.33); ORs were also significantly elevated for cardiovascular, gastrointestinal, nervous system, genitourinary, and musculoskeletal but not orofacial birth defects. The ORs were smaller and less likely to be statistically significant in adjusted analyses. These meta-analyses had strengths but also shortcomings. The strengths and shortcomings are explained in detail so that readers obtain a better understanding of how to critically assess findings in meta-analyses. One strength was the presentation of both unadjusted and adjusted pooled estimates; the former allow an understanding of risks in the average real world patient and the latter allow an understanding of the unique contribution of the exposure to the outcomes. Another strength was the presentation of cumulative meta-analyses which demonstrated from which calendar year onwards a finding became consistently statistically significant in the scientific literature. One shortcoming, in analyses of subcategories of birth defects, was the repeated representation of the same sample in the same forest plot; the many reasons why this is problematic are explained. Another shortcoming was the pooling of ORs obtained from cohort studies with those obtained from case control studies; conceptual and numerical reasons why this is problematic are also explained.
