ABSTRACT

BACKGROUND & AIMS: Objectives of this retrospective cohort study were to assess differences in patient survival between etiologies of cirrhosis while on the waitlist for liver transplantation (LT), and to identify cardiac risk factors that predict survival failure while on the waitlist for LT.

METHODS: This single-center retrospective cohort design included adult patients who were listed for LT at a tertiary academic hospital with a high-volume liver transplant center.

RESULTS: Of the 653 patients listed for LT during the study period, 507 (77.6%) survived to transplant and 146 (22.4%) died or clinically deteriorated prior to transplant. Cumulative incidence of death or clinical deterioration did not differ statistically between patient groups (log rank p = .11). In multivariate analysis, compared to patients with NAFLD, there were no significant differences between patients with alcoholic cirrhosis (HR .95, 95%, CI, .62-1.45), cryptogenic cirrhosis (HR 1.31, 95%, CI, .77-2.23), or hepatitis C cirrhosis (HR 1.12, 95%, CI, .66-1.90). However, higher MELD scores (HR = 1.52, 95% CI, 1.12-1.19), severe coronary artery disease (HR = 2.09 95% CI, 1.23-3.55), and tricuspid regurgitation (HR = 2.62, 95% CI, 1.31-5.26) were independently associated with increased risk for survival failure to LT.

CONCLUSIONS: The presence of severe coronary artery disease and tricuspid regurgitation at the time of listing for transplant are associated with survival failure while on the LT waitlist across etiologies of liver disease. Diagnostic assessment of coronary and valvular disease should be considered in all patients undergoing evaluation for LT, such as cardiac catheterization and/or stress echocardiogram.

ABSTRACT

OBJECTIVES: Several studies have investigated that anticholinergic drugs cause cognitive impairment. However, the risk of dementia associated with anticholinergics has not been extensively investigated in the super-aging society of Japan. We conducted this study to assess the association between anticholinergic drugs and the risk of dementia in older adults in Japan.

METHODS: This nested case-control study used data from the Longevity Improvement & Fair Evidence Study, which includes claim data in Japan from 2014 to 2020. We included 66,478 cases of diagnosed dementia and 328,919 matched controls aged ≥65 years, matched by age, sex, municipality, and cohort entry year. Primary exposure was the total cumulative anticholinergic drugs prescribed from cohort entry date to event date or matched index date, which was the total standardized daily doses for each patient, calculated by adding the total dose of different types of anticholinergic drugs in each prescription, divided by the World Health Organization-defined daily dose values. Odds ratios for dementia associated with cumulative exposure to anticholinergic drugs were calculated using conditional logistic regression adjusted for confounding variables.

RESULTS: The mean (standard deviation) age at index date was 84.3 (6.9), and the percentage of women was 62.1%. From cohort entry date to event date or matched index date, 18.8% of the case patients and 13.7% of the controls were prescribed at least one anticholinergic drug. In the multivariable-adjusted model, individuals with anticholinergic drugs prescribed had significantly higher odds of being diagnosed with dementia (adjusted odds ratio, 1.50 [95% confidence interval, 1.47-1.54]). Among specific types of anticholinergic drugs, a significant increase in risk was observed with the use of antidepressants, antiparkinsonian drugs, antipsychotics, and bladder antimuscarinics in a fully multivariable-adjusted model.

CONCLUSIONS: Several types of anticholinergic drugs used by older adults in Japan are associated with an increased risk of dementia. These findings suggest that the underlying risks should be considered alongside the benefits of prescribing anticholinergic drugs to this population.

ABSTRACT

INTRODUCTION: The community health agent plays an essential role as a link between the community and health institutions; the effectiveness of their work is crucial in promoting health, prevention, and detection of diseases. Motivation and empowerment could affect the performance of the community agent in carrying out his work.

OBJECTIVE: To determine if work motivation and empowerment are factors associated with the self-efficacy of the community health agent.

METHODOLOGY: Observational and cross-sectional study. The study included community health agents in the Non-Governmental Organization ADRA in Imbabura and Pichincha, Ecuador. The sample selected by the census method corresponds to 300 agents. The instruments were the Motivation at Work Scale (R-MAWS), the Psychological Empowerment Scale, and the Professional Self-efficacy Questionnaire (AU10). Descriptive statistical analyses were performed using dispersion and summary measures-a comparative analysis with chi-square. The inferential analysis was done through logistic regression where the B coefficient and the odds ratio (OR) with 95% confidence intervals (CI) were evaluated, P < .05. The theoretical and adjusted model of the structural model allowed us to corroborate the association of the variables.

RESULTS: Motivation had a positive effect on self-efficacy (OR = 10.091, CI [5.509-18.485], P < .05), empowerment had a minimal effect (OR = 0.664, CI [0.363-1.214], P > .05), which is not significant to predict the perception of self-efficacy.

CONCLUSION: This study suggests that to improve the self-efficacy of the work of community health agents, it is necessary to intervene through strategies that keep them motivated in the exercise of their mediation work between the community and health institutions. Likewise, empowering them would contribute to self-efficacy and thus help in the fulfillment of the functions of health agents.

ABSTRACT

Radicalization to terrorism is a multifaceted process with no single theory or approach to explain it. Although research has focused on understanding the process, there is still a dearth of studies that examine an empirically driven pathway to terrorism behavior. This study examines a cross-sectional sample of incarcerated men convicted of terrorism in Iraq (N = 160). A questionnaire-guided interview included adverse childhood experiences (ACEs), conduct disorder (CD), antisocial personality disorder (ASPD), religious and political ideology, views about causes of terrorism, and the severity of terrorist acts. Path analysis was employed to examine the relationships between these factors and to identify the model with the best fit. After adjusting for age, employment, and location, results indicated that ACEs positively impacted CD, ASPD, religious guidance, and terrorism attitudes. ASPD positively affected political commitment and terrorism attitudes, but inversely affected current religious commitment. Political commitment inversely influenced terrorism attitudes. Religious commitment positively influenced the prioritization of religion in life, which subsequently impacted terrorism attitudes and behavior severity. Additionally, attitudes toward terrorism directly affected the severity of terrorism behavior. All paths in the final model were statistically significant at p < 0.05. Although these findings may be limited in generalizability due to the unique sample, results support the complex and interdependent nature of childhood and adult experiences on the development of both terrorism attitudes and the severity of terrorism behavior.

ABSTRACT

PURPOSE: High Magnification Module (HMM™, Heidelberg Engineering, Heidelberg, Germany) imaging is a novel technique, designed to visualize the retina at a cellular level. To assess the potential of HMM™-based metrics as endpoints for future trials, we evaluated correlations between structural HMM™ cone metrics, spectral-domain OCT (SD-OCT, Heidelberg Engineering, Heidelberg, Germany) and retinal sensitivity on microperimetry (MP, MAIA, CenterVue, Padova, Italy) in healthy subjects and p.(Arg142Trp) PRPH2-associated Central Areolar Choroidal Dystrophy (CACD) patients.

METHODS: We projected a default 10° MP grid on composite HMM™ images and performed automated cone density (CD), intercell distance (ICD) and nearest neighbour distance (NND) analysis at stimuli located at 3° and 5° retinal eccentricity. We manually measured intrasubject outer retinal thickness on SD-OCT in absolute and relative scotomas, located outside of focal atrophy.

RESULTS: We included 15 CACD patients and five healthy subjects. We found moderate-to-strong correlations of HMM™ metrics and MP sensitivity at 3° eccentricity from the fovea. We found the outer retina at the locations of absolute scotomas to be statistically significant thinner (p = 0.000003, one-sample t-test), as the outer retinal thickness at locations of relative scotomas. Interestingly, HMM™ metrics of these areas did not differ significantly.

CONCLUSIONS: We found significant correlations between structural photoreceptors metrics on HMM™ imaging and retinal sensitivity on MP in healthy subjects and CACD patients. A multimodal approach, combining SD-OCT, MP and HMM™ imaging, allows for detailed mapping of retinal photoreceptor integrity and restitution potential, important data that could serve as biomarkers in future clinical trials.

ABSTRACT

OBJECTIVE: Child maltreatment, dissociation and dissociative disorders have been noted in relationship to eating disorders (EDs) for decades, and their co-occurrence generally is associated with greater morbidity, self-harm and mortality. The concomitant presentation of dissociative identity disorder (DID) with an ED (ED + DID) is especially challenging, and there is limited information on approaches to and the effects of integrated treatment for this serious comorbidity, especially in higher levels of care. There are also limited treatment resources for such patients, since they are often turned away from specialty units due to lack of expertise with or bias toward one or the other disorder.

METHOD: We report our experience with a case series of 18 patients with DSM-5 defined ED + DID (mean age (SD) = 32.6 (11.8) years) admitted to residential treatment (RT) and assessed using validated measures for symptoms of ED, major depression (MD), PTSD, state-trait anxiety, quality of life (QOL), age of ED onset, and family involvement during treatment. All patients received integrated, multimodal, trauma-focused approaches including those based on DID practice guidelines, principles of cognitive processing therapy (CPT), and other evidence-based approaches. Fifteen of 18 patients also completed discharge reassessments, which were compared to admission values using paired t-tests.

RESULTS: Following integrated, trauma-focused RT, patients with ED + DID demonstrated statistically significant improvements in all measures, with medium (anxiety) to high (ED, PTSD, MD, QOL) effect sizes.

DISCUSSION: These results provide positive proof of concept that patients with ED + DID can be effectively treated in a specialty, trauma-focused ED program at higher levels of care.

PUBLIC SIGNIFICANCE: EDs and dissociative identity disorder (DID) are related conditions, but little is known about treating patients with both conditions. We describe the clinical features and integrated treatment of 18 such patients, 15 of whom completed discharge assessments. Significant clinical improvements were found in multiple domains (ED, PTSD, mood, anxiety, quality of life), which demonstrate positive proof of concept that ED + DID can be effectively treated in a specialty, trauma-focused ED program.

ABSTRACT

Cancer progression and treatment can be informed by reconstructing its evolutionary history from tumor cells. Although many methods exist to estimate evolutionary trees (called phylogenies) from molecular sequences, traditional approaches assume the input data are error-free and the output tree is fully resolved. These assumptions are challenged in tumor phylogenetics because single-cell sequencing produces sparse, error-ridden data and because tumors evolve clonally. Here, we study the theoretical utility of methods based on quartets (four-leaf, unrooted phylogenetic trees) in light of these barriers. We consider a popular tumor phylogenetics model, in which mutations arise on a (highly unresolved) tree and then (unbiased) errors and missing values are introduced. Quartets are then implied by mutations present in two cells and absent from two cells. Our main result is that the most probable quartet identifies the unrooted model tree on four cells. This motivates seeking a tree such that the number of quartets shared between it and the input mutations is maximized. We prove an optimal solution to this problem is a consistent estimator of the unrooted cell lineage tree; this guarantee includes the case where the model tree is highly unresolved, with error defined as the number of false negative branches. Lastly, we outline how quartet-based methods might be employed when there are copy number aberrations and other challenges specific to tumor phylogenetics.

ABSTRACT

BACKGROUND: The human papillomavirus (HPV) vaccination helps the body fight off certain types of the virus. Despite being one of the top 10 health hazards in the world, vaccination hesitancy has received little attention in Ethiopia. In Jimma Town, Ethiopia, the current study aims to identify the variables that affect HPV vaccine resistance and evaluate HPV uptake resistance and related variables among female school students.

METHODS: A mixed study of quantitative and qualitative data collection and analysis were considered. An institution-based cross-sectional study was conducted from December 2022 to June 2023. Following a thorough random sampling process, 373 respondents were selected using stratified sampling techniques. The necessary information was gathered using an in-depth interview, a structured questionnaire administered using Kobotoolbox tools, and an interviewer who had undergone training. Models of multivariable and bivariate logistic regression were both used.

RESULT: A total of 369 respondents participated in the study and the response rate was 98.9%. The hesitancy of the HPV vaccine in Jimma Town female school students was 39.02%. Female students who have a mobile phone, (OR = 0.46, 95% CI (1.16, 45.89), mothers educational status ([Formula: see text] Secondary) (OR = 0.53, 95% CI (1.11, 2.44), older sister vaccinated (OR = 0.19, 95% CI (0.004, 0.42), previously vaccinated two doses of HPV (OR=0.64, 95% CI (0.006, 0.137), Confidence (worried in safety and efficacy of vaccine) (OR = 3.42, 95% CI (0.30, 0.87), Not Belief in rumors (HPV vaccine ruins girls fertility) (OR = 0.21, 95% CI (0.43, 0.96), and Complacency (Distrust in health care information ) (OR = 0.24, 95% CI (0.37, 0.94), were found to be statistically significant with HPV Vaccine Hesitancy.

CONCLUSION: Due to widespread misinformation in the community, both schoolgirls and parents had high levels of hesitancy for the HPV vaccine in this study compared to a similar study. As a result, the HPV vaccine program, with the help of the appropriate health care professionals, should work hard to maximize community awareness in order to significantly increase the uptake of the HPV vaccine.

ABSTRACT

BACKGROUND: Patients with preoperative anemia have a higher risk of requiring blood transfusion after major orthopedic surgery due to increased blood loss and closer transfusion thresholds. Various patient blood management (PBM) policies aim to reduce transfusion rates. This observational study aimed to investigate blood loss and evaluate the effectiveness of an adjusted surgical PBM protocol in patients with anemic chronic disease (ACD) undergoing elective total knee arthroplasty (TKA).

METHODS: A consecutive cohort of patients underwent elective unilateral TKA with an adjusted PBM protocol. The protocol consisted of epoetin (EPO) alfa therapy prescribed by the surgeon, routine administration of tranexamic acid (TXA), and standardized postoperative pharmacologic prophylaxis for thromboembolism. The performance of this PBM protocol was analyzed in patients with a baseline hemoglobin level of less than 12 g/dl. Hemoglobin levels were controlled at admission, on postoperative day (POD) 1, and on POD 7 ± 1. A bleeding index (BI-7) was used as an estimate of blood loss up until POD 7. Multiple linear regression was used to assess whether there were any differences in BI-7 between ACD- and ACD + patients.

RESULTS: A total of 751 patients with complete hemoglobin monitoring were included in the study. Of these patients, 68 (9.1%) had a baseline hemoglobin concentration of less than 12 g/dl (ACD group). In this group, 28 patients (41.2%) received preoperative EPO therapy. The mean adjusted BI-7 for the study population was 3.0 (95% CI, 2.9 to 3.0) g/dl in the ACD- group and 2.3 (95% CI, 2.0-2.6) g/dl in the ACD + group. The difference in BI-7 was statistically significant (difference, 0.6 [95% CI: 0.3 to 0.9] g/dl, p < 0.001). No major complications occurred in the ACD + group, whereas there were three complications in the ACD- group (p = 1.00).

CONCLUSIONS: ACD patients undergoing TKA did not have an increased risk of bleeding or bleeding complications with the use of the adjusted PBM protocol. None of ACD patients required transfusion. ACD patients undergoing TKA experienced significantly less blood loss than patients with no preoperative anemia with the use of the adjusted PBM. We now consider the use of EPO in ACD patients with no nutritional deficiencies undergoing TKA at a baseline hemoglobin level of 11 g/dl. However, this should be validated in larger cohorts with a higher prevalence of ACD patients.

ABSTRACT

BACKGROUND: Cardiovascular disease (CVD) and diabetes mellitus are major health issues in Tonga and other Pacific countries, although mortality levels and trends are unclear. We assess the impacts of cause-of-death certification on coding of CVD and diabetes as underlying causes of death (UCoD).

METHODS: Tongan records containing cause-of-death data (2001-2018), including medical certificates of cause-of-death (MCCD), had UCoD assigned according to International Classification of Diseases 10th revision (ICD-10) coding rules. Deaths without recorded cause were included to ascertain total mortality. Diabetes and hypertension causes were reallocated from Part 1 of the MCCD (direct cause) to Part 2 (contributory cause) if potentially fatal complications were not recorded, and an alternative UCoD was assigned. Proportional mortality by cause based on the alternative UCoD were applied to total deaths then mortality rates calculated by age and sex using census/intercensal population estimates. CVD and diabetes mortality rates for unaltered and alternative UCoD were compared using Poisson regression.

RESULTS: Over 2001-18, in ages 35-59 years, alternative CVD mortality was higher than unaltered CVD mortality in men (p = 0.043) and women (p = 0.15); for 2010-18, alternative versus unaltered measures in men were 3.3/10³ (95%CI: 3.0-3.7/10³) versus 2.9/10³ (95%CI: 2.6-3.2/10³), and in women were 1.1/10³ (95%CI: 0.9-1.3/10³) versus 0.9/10³ (95%CI: 0.8-1.1/10³). Conversely, alternative diabetes mortality rates were significantly lower than the unaltered rates over 2001-18 in men (p < 0.0001) and women (p = 0.013); for 2010-18, these measures in men were 1.3/10³ (95%CI: 1.1-1.5/10³) versus 1.9/10³ (95%CI: 1.6-2.2/10³), and in women were 1.4/10³ (95%CI: 1.2-1.7/10³) versus 1.7/10³ (95%CI: 1.5-2.0/10³). Diabetes mortality rates increased significantly over 2001-18 in men (unaltered: p < 0.0001; alternative: p = 0.0007) and increased overall in women (unaltered: p = 0.0015; alternative: p = 0.014).

CONCLUSIONS: Diabetes reporting in Part 1 of the MCCD, without potentially fatal diabetes complications, has led to over-estimation of diabetes, and under-estimation of CVD, as UCoD in Tonga. This indicates the importance of controlling various modifiable risks for atherosclerotic CVD (including stroke) including hypertension, tobacco use, and saturated fat intake, besides obesity and diabetes. Accurate certification of diabetes as a direct cause of death (Part 1) or contributory factor (Part 2) is needed to ensure that valid UCoD are assigned. Examination of multiple cause-of-death data can improve understanding of the underlying causes of premature mortality to better inform health planning.
