ABSTRACT

BACKGROUND AND AIM: The aim was to investigate the association between sarcoidosis and anxiety and/or depression (A/D) in patients with sarcoidosis and comparators matched on age, gender, residency, and cohabitation status.

METHODS: Patients with newly diagnosed sarcoidosis between 2001 and 2015 were identified in the Danish National Patient Register. Cases were matched 1:4 with non-sarcoidosis comparators. We estimated the cumulative incidence of A/D using the Cumulative Incidence Function and the subdistribution hazard ratio (sHR) for A/D using the Fine-Gray subdistribution hazard model. Estimates were adjusted for socio-economic status and Deyo-Charlson Comorbidity Index.

RESULTS: We identified 7.302 cases and 26.145 matched comparators. The cumulative incidence of A/D after five years was 6.0% (95%CI 5.5-6.4) for cases and 4.2% (95%CI 4.0-4.4) for matched comparators. The cumulative incidence was higher among cases for both males and females and in all age-groups compared with the matched comparators. The adjusted-sHR for A/D was 1.38 (95%CI 1.24-1.53). The adjusted-sHR for A/D was 1.51 (95%CI 1.30-1.75) for male cases and 1.25 (95%CI 1.08-1.45) for female cases compared with the matched comparators. The adjusted-sHR for A/D was higher for cases in all age-groups compared with the matched comparators, although not statistically significant among cases aged 30-39 years (a-sHR 1.15; 95%CI 0.92-1.44).

CONCLUSIONS: Sarcoidosis cases had a higher risk of A/D compared with matched comparators during 18 years of follow-up. The risk of developing A/D was greater for male and female cases and within all age-groups compared with the matched comparators.

ABSTRACT

BACKGROUND: The Fontan operation is a palliative technique for patients born with single ventricle heart disease. The superior vena cava (SVC), inferior vena cava (IVC), and hepatic veins are connected to the pulmonary arteries in a total cavopulmonary connection by an extracardiac conduit or a lateral tunnel connection. A balanced hepatic flow distribution (HFD) to both lungs is essential to prevent pulmonary arteriovenous malformations and cyanosis. HFD is highly dependent on the local hemodynamics. The effect of age-related changes in caval inflows on HFD was evaluated using cardiac magnetic resonance data and patient-specific computational fluid dynamics modeling.

METHODS: SVC and IVC flow from 414 patients with Fontan were collected to establish a relationship between SVC:IVC flow ratio and age. Computational fluid dynamics modeling was performed in 60 (30 extracardiac and 30 lateral tunnel) patient models to quantify the HFD that corresponded to patient ages of 3, 8, and 15 years, respectively.

RESULTS: SVC:IVC flow ratio inverted at ≈8 years of age, indicating a clear shift to lower body flow predominance. Our data showed that variation of HFD in response to age-related changes in caval inflows (SVC:IVC, 2, 1, and 0.5 corresponded to ages, 3, 8, and 15+, respectively) was not significant for extracardiac but statistically significant for lateral tunnel cohorts. For all 3 caval inflow ratios, a positive correlation existed between the IVC flow distribution to both the lungs and the HFD. However, as the SVC:IVC ratio changed from 2 to 0.5 (age, 3-15+) years, the correlation’s strength decreased from 0.87 to 0.64, due to potential flow perturbation as IVC flow momentum increased.

CONCLUSIONS: Our analysis provided quantitative insights into the impact of the changing caval inflows on Fontan’s long-term HFD, highlighting the importance of SVC:IVC variations over time on Fontan’s long-term hemodynamics. These findings broaden our understanding of Fontan hemodynamics and patient outcomes.

ABSTRACT

A timely response to patient-initiated telephone calls can affect many aspects of patient health, including quality of care and health equity. Historically, at a family medicine residency clinic, at least 1 out of 4 patient calls remained unresolved three days after the call was placed. We sought to explore whether there were differential delays in resolution of patient concerns for certain groups and how these were affected by quality improvement interventions to increase responsiveness to patient calls. A multidisciplinary team at a primary care residency clinic applied Lean education and tools to improve the timeliness of addressing telephone encounters. Telephone encounter data were obtained for one year before and nine months after the intervention. Data were stratified by race, ethnicity, preferred language, sex, online portal activation status, age category, zip code, patient risk category, and reason for call. Stratified data revealed consistently worse performance on telephone encounter closure by 72 hours for Black/African American patients compared to Hispanic and non-Hispanic White patients pre-intervention. Interventions resulted in statistically significant overall improvement, with an OR of 2.9 (95% CI: 2.62 to 3.21). Though interventions did not target a specific population, pre-intervention differences based on race and ethnicity resolved post-intervention. Telephone calls serve as an important means of patient communication with care teams. General interventions to improve the timeliness of addressing telephone encounters can lead to sustainable improvement in a primary care academic clinic and may also alleviate disparities.

ABSTRACT

INTRODUCTION: The p53 gene mutation is one of the most common genetic alterations in many cancers. In prostate cancer (PCa), it has been associated with a poor prognosis, tumor progression and aggressiveness. P53 mutation induces an abnormal protein expression in related tissues.

AIM: This study aimed to assess p53 expression using immunohistochemistry in PCa and to discuss its prognostic value.

METHODS: We have retrospectively collected all cases of PCa diagnosed in our pathology department between 2012 and 2022. An automatized immunohistochemical analysis was performed using monoclonal p53 antibody. For each case, we assessed the proportion of positive cells and the intensity of staining. P53 expression was considered abnormal when it was totally negative or overexpressed (>=50% of positive cells).

RESULTS: Twenty-four cases have been selected. Abnormal p53 expression was found in 42% of cases (P53 was overexpressed in 6cases and totally negative in 4 cases). Mean age of patients with p53 abnormal expression was 70years old. Patients with p53 abnormal expression had Gleason score >7 in 5 cases, ISUP grade >2 in 3 cases, peri-neural invasion in 8cases, capsule invasion in 9cases. All patients with p53 overexpression developed androgen resistance (p<0.01).

CONCLUSION: An aberrant expression profile of the p53 protein was observed in 42% of cases, and a statistically significant association was found with androgen resistance. Our results suggest a potential prognostic role of p53 in PCa.

ABSTRACT

INTRODUCTION: Although glioblastoma (GBM) has a very poor prognosis, overall survival (OS) in treated patients shows great difference varying from few days to several months. Identifying factors explaining this difference would improve management of patient treatment.

AIM: To determine the relevance of diffusion restriction in newly diagnosed treatment-naïve GBM patients.

METHODS: Preoperative magnetic resonance scans of 33 patients with GBM were reviewed. Regions of interest including all the T2 hyperintense lesion were drawn on diffusion weighted B0 images and transferred to the apparent diffusion coefficient (ADC) map. For each patient, a histogram displaying the ADC values within in the regions of interest was generated. Volumetric parameters including tumor regions with restricted diffusion, parameters derived from histogram and mean ADC value of the tumor were calculated. Their relationship with OS was analyzed.

RESULTS: Patients with mean ADC value < 1415×10-6 mm2/s had a significantly shorter OS (p=0.021). Among volumetric parameters, the percentage of volume within T2 lesion with a normalized ADC value <1.5 times that in white matter was significantly associated with OS (p=0.0045). Patients with a percentage>23.92% had a shorter OS. Among parameters derived from histogram, the 50th percentile showed a trend towards significance for OS (p=0.055) with patients living longer when having higher values of 50th percentile. A difference in OS was observed between patients according to ADC peak of histogram but this difference did not reach statistical significance (p=0.0959).

CONCLUSION: Diffusion magnetic resonance imaging may provide useful information for predicting GBM prognosis.

ABSTRACT

INTRODUCTION: Considering the growing global need and the complexity of health conditions, an intensive rehabilitation in inpatient departments is fundamental. Yet, in Tunisia, the distribution of Inpatient Rehabilitation Facilities is not illustrated.

AIM: To perform an update concerning the rehabilitation’s beds-ratio /1000 Tunisian-inhabitants in 2023.

METHODS: Data were collected from the Tunisian Ministry of Health, the Eastern Mediterranean Regional Office, and the National Institute of Statistics websites.

RESULTS: The findings revealed a total number of rehabilitations’ beds 132 among a total of 20000 hospital beds with a rehabilitations’ beds-ratio equal to 0.01/1000 inhabitants. Only three Inpatient Rehabilitation Facilities were identified in Tunisia covering the Greater Tunis, North East, and Center east districts. There was inequity of distribution since the beds ratio is 1.07/1000 in the North east, 0.02/1000 in the Greater Tunis and 0 in the North West and the South of Tunisia.

CONCLUSION: This update highlighted the alarmingly low rehabilitation’s beds-ratio in Tunisia, coupled to a significant regional disparity. Increasing beds in the existing Inpatient Rehabilitation Facilities and extending outpatient rehabilitation departments with inpatient units might be considered urgent solutions.

ABSTRACT

Understanding whether and how treatment effects vary across subgroups is crucial to inform clinical practice and recommendations. Accordingly, the assessment of heterogeneous treatment effects based on pre-specified potential effect modifiers has become a common goal in modern randomized trials. However, when one or more potential effect modifiers are missing, complete-case analysis may lead to bias and under-coverage. While statistical methods for handling missing data have been proposed and compared for individually randomized trials with missing effect modifier data, few guidelines exist for the cluster-randomized setting, where intracluster correlations in the effect modifiers, outcomes, or even missingness mechanisms may introduce further threats to accurate assessment of heterogeneous treatment effect. In this article, the performance of several missing data methods are compared through a simulation study of cluster-randomized trials with continuous outcome and missing binary effect modifier data, and further illustrated using real data from the Work, Family, and Health Study. Our results suggest that multilevel multiple imputation and Bayesian multilevel multiple imputation have better performance than other available methods, and that Bayesian multilevel multiple imputation has lower bias and closer to nominal coverage than standard multilevel multiple imputation when there are model specification or compatibility issues.

ABSTRACT

BACKGROUND: COVID-19 vaccines for public use were approved at the turn of 2020 and 2021. The level of vaccination coverage against COVID-19 in Poland is one of the lowest in Europe. Despite scientific studies there are people who are afraid of vaccinations and spread false information about them. Vaccinations against COVID-19 allowed us to learn about the attitudes of people who decided to be vaccinated, which can be used to improve the effectiveness of the infectious diseases prevention in the work and public environment. The aim of the study was to analyze the main reasons determining a decision to get vaccinated against COVID-19.

MATERIAL AND METHODS: The study was carried on among all the people who decided to be vaccinated against COVID-19 in Nofer Institute of Occupational Medicine in Łódź. All vaccinated people completed an anonymous survey containing questions related to the most important factors, which encouraged them to undergo this vaccination.

RESULTS: The study involved 945 people vaccinated against COVID-19. Statistical significance was revealed between 3 different reasons (one’s own health, stress-free work, safe travelling and easier access to entertainment) for getting vaccinated and age, gender and a form of employment. The authors also found statistical significance of the correlation between the age, gender, education and form of employment of the respondents and the reason for choosing the specific vaccine product.

CONCLUSIONS: Despite evidence presented by scientists about the effectiveness and safety of vaccinations, many people refused and still refuse to receive the vaccine. In order to increase the readiness of the population for vaccinations against COVID-19 and subsequent ones, if there is a need to limit new epidemics, the following should be done: introduce activities to raise health awareness, intensify strategies and campaigns aimed at increasing public trust in available vaccines against COVID-19, devolop individualized messages that contribute to vaccine hesitancy.

ABSTRACT

BACKGROUND: There is an ongoing debate regarding the comparative merits of splenectomy (SP) and splenic preservation in the surgical management of gastric cancer. This systematic review and meta-analysis aims to shed light on potential differences in survival outcomes and postoperative complications associated with these two procedures.

METHOD: An exhaustive literature search was conducted across multiple databases, namely PubMed, Embase, Cochrane Library, and Web of Science. We utilized a random-effects model via RevMan 5.4 software to conduct a meta-analysis of the hazard ratios (HRs) and risk ratios (RRs) associated with SP and spleen preservation. Subgroup analyses were based on various attributes of the included studies. We employed funnel plots to assess publication bias, and sensitivity analysis was conducted to gauge the stability of the combined results. Both funnel plots and sensitivity analysis were performed using Stata 12.

RESULT: Our research incorporated 23 observational studies and three randomized controlled trials, involving a total of 6,255 patients. SP did not yield superior survival outcomes in comparison to splenic preservation, a conclusion that aligns with the combined results of the randomized controlled trials. No statistically significant difference in survival prognosis was observed between SP and splenic preservation, irrespective of whether the patients had proximal gastric cancer or proximal gastric cancer invading the stomach’s greater curvature. SP exhibited a higher incidence of all postoperative complications, notably pancreatic fistula and intraabdominal abscesses. However, it did not significantly differ from splenic preservation in terms of anastomotic leakage, incision infection, intestinal obstruction, intra-abdominal bleeding, and pulmonary infection. No significant difference in postoperative mortality between SP and splenic preservation was found. Funnel plots suggested no notable publication bias, and sensitivity analysis affirmed the stability of the combined outcomes.

CONCLUSION: Despite the lack of significant differences in certain individual complications and postoperative mortality, the broader pattern of our data suggests that SP is associated with a greater overall frequency of postoperative complications, without providing additional survival benefits compared to splenic preservation. Thus, the routine implementation of SP is not advocated.

ABSTRACT

Lesbian, gay and bisexual people are disadvantaged in terms of health and socio-economic status compared with heterosexual people, yet findings pertaining to educational outcomes vary depending on the specific identity and gender considered. This study delves into these unexplained findings by applying a social-stratification lens, thereby providing an account of how intergenerational educational mobility varies by sexual identity. To accomplish this, we use representative data from five OECD countries and a regression-based empirical specification relying on coarsened exact matching. We find that gay and lesbian people have higher educational attainment than heterosexual people in all five countries and that these higher levels of education stem from greater rates of upward educational mobility among gay/lesbian people. There were, however, few differences between heterosexual and bisexual people. Variation across countries emerged when analyses were stratified by gender, with higher rates of upward mobility observed for gay men in Australia, Chile, the United Kingdom, and the United States and lesbian women in Australia and Germany. Overall, our results align with previous claims that education can be a strategy for gay/lesbian people to avoid actual or anticipated discrimination. However, variation in these patterns across groups suggests that other mechanisms may also be at play.
