Covid-19 and Its Impact on Colorectal Cancer Diagnosis in Romania: A Single-Centered 5-year Retrospective Cohort Study

Chirurgia (Bucur). 2023 Oct;118(5):487-501. doi: 10.21614/chirurgia.2023.v.118.i.5.p.487.

ABSTRACT

Background: Colorectal cancer, 3rd in incidence and 2nd in mortality among cancers worldwide, represents the most common malignant tumor of the digestive tract. In Romania, it is the most frequently diagnosed type of cancer (approximately 0.06% of the population/year). During the COVID-19 pandemic the legislation preventing the SARS-CoV-2 viral transmission impairing access to outpatient healthcare services combined with patients fear of SARS-CoV-2 infection had consequences on the diagnosis and treatment of all other pathologies. Methods: A 5-year retrospective cohort study was conducted in a tertiary hospital in Arad, Romania, and included 1329 newly diagnosed colorectal cancer patients. For statistical analysis, Fisher’s exact test was used for categorical data and the unpaired test with Welch’s correction for continuous data. Results: The age on diagnosis decreased during the early COVID-19 pandemic to 68.50 (95% CI [67.90 69.11]) years, with the highest percentage (7.41%) of early onset colorectal cancer patients, a steady post-pandemic increase in the percentage of male (52.71% in 2019 to 62.20% in 2022) and urban (54.18% in 2018 to 70.10% in 2022) patients, admitted to the hospital due to an emergency presentation (peaking at 83.95% in 2020) and requiring a longer hospitalization period (10.03 [95% CI (8.76-11.30)] days in 2020 to 8.37 [95% CI (7.44-9.30)] days in 2022). The most common colo-rectal cancer diagnosis of patients in our reference population was malignant neoplasm of the rectum (ICD-10 code C20.0), while the most common complications were peritumoral adherence-related disorder, occlusion, and perforation, encountered in patients with comorbidities such as arterial hypertension, ischemic cardiomyopathy, diabetes mellitus, obesity, and non-alcoholic steatohepatitis. Conclusions: Regional particularities should be analyzed to better target the population at risk and to better direct the necessary healthcare resources towards the reference population, especially during crisis periods similar to the COVID-19 pandemic.

Tips and Tricks for a Successful Literature Review as Part of Medical Career Development

Chirurgia (Bucur). 2023 Oct;118(5):445-454. doi: 10.21614/chirurgia.2023.v.118.i.5.p.445.

ABSTRACT

The literature review is a direct consequence of the increased volume of scientific information, becoming a necessity not only for the medical field. Such material, properly done, is of great use to any professional who wishes to keep abreast of the latest knowledge and concepts. The proposed goal is to help and guide resident doctors, doctoral students, and young researchers in understanding the concepts that are the basis of conducting a literature review and acquiring the generally accepted methodology for conducting it. The selection of information sources, accessing databases, the concept of peer-review, indexing and the impact factor are clearly presented as elements that cannot be neglected in the valorisation of scientific information sources. The structure of a literature review must consider the generally accepted format for such an article, with each chapter having its own importance. Depending on the quality and heterogeneity of the results obtained after analysing the collected data, the review can be structured narratively or systematically, the homogeneity of the results allowing the application of statistical study methods (meta-analysis). Although it seems difficult, conducting a literature review is easier and faster than developing an original study based on experimental or clinical scientific research. The literature review can be carried out in comfortable conditions, online, regardless of location and is a welcome support in the development of the professional and scientific career.

Early antenatal risk factors for births before arrival: An unmatched case-control study

Acta Obstet Gynecol Scand. 2023 Nov 15. doi: 10.1111/aogs.14720. Online ahead of print.

ABSTRACT

INTRODUCTION: Birth before arrival is associated with maternal morbidity and neonatal morbidity and mortality. Yet, timely risk stratification remains challenging. Our objective was to identify risk factors for birth before arrival which may be determined at the first antenatal appointment.

MATERIAL AND METHODS: This was an unmatched case-control study involving 37 348 persons who gave birth at a minimum of 22+0 weeks’ gestation over a 5-year period from January 2014 to October 2019 (IRAS project ID 222260; REC reference: 17/SC/0374). The setting was a large UK university hospital. Data obtained on maternal characteristics at booking was examined for association with birth before arrival using a stepwise multivariable logistic regression analysis. Data are presented as adjusted odds ratios with 95% confidence intervals. Area under the receiver-operator characteristic curves (C-statistic) were employed to enable discriminant analysis assessing the risk prediction of the booking data on the outcome.

RESULTS: Multivariable analysis identified significant independent predictors of birth before arrival that were detectable at booking: parity, ethnicity, multiple deprivation, employment status, timing of booking, distance from home to the nearest maternity unit, and safeguarding concerns raised at booking by clinical staff. Our model demonstrated good discrimination for birth before arrival; together, the predictors accounted for 77% of the data variance (95% confidence interval 0.74-0.80).

CONCLUSIONS: Information gathered routinely at booking may discriminate individuals at risk for birth before arrival. Better recognition of early factors may enable maternity staff to direct higher-risk women towards specialized care services at an early point in their pregnancy, enabling time for clinical and social interventions.

ConSpaS: a contrastive learning framework for identifying spatial domains by integrating local and global similarities

Brief Bioinform. 2023 Sep 22;24(6):bbad395. doi: 10.1093/bib/bbad395.

ABSTRACT

Spatial transcriptomics is a rapidly growing field that aims to comprehensively characterize tissue organization and architecture at single-cell or sub-cellular resolution using spatial information. Such techniques provide a solid foundation for the mechanistic understanding of many biological processes in both health and disease that cannot be obtained using traditional technologies. Several methods have been proposed to decipher the spatial context of spots in tissue using spatial information. However, when spatial information and gene expression profiles are integrated, most methods only consider the local similarity of spatial information. As they do not consider the global semantic structure, spatial domain identification methods encounter poor or over-smoothed clusters. We developed ConSpaS, a novel node representation learning framework that precisely deciphers spatial domains by integrating local and global similarities based on graph autoencoder (GAE) and contrastive learning (CL). The GAE effectively integrates spatial information using local similarity and gene expression profiles, thereby ensuring that cluster assignment is spatially continuous. To improve the characterization of the global similarity of gene expression data, we adopt CL to consider the global semantic information. We propose an augmentation-free mechanism to construct global positive samples and use a semi-easy sampling strategy to define negative samples. We validated ConSpaS on multiple tissue types and technology platforms by comparing it with existing typical methods. The experimental results confirmed that ConSpaS effectively improved the identification accuracy of spatial domains with biologically meaningful spatial patterns, and denoised gene expression data while maintaining the spatial expression pattern. Furthermore, our proposed method better depicted the spatial trajectory by integrating local and global similarities.

Long Term Effects of a Social Capital-Based Exercise Adherence Intervention for Breast Cancer Survivors With Moderate Fatigue: A Randomized Controlled Trial

Integr Cancer Ther. 2023 Jan-Dec;22:15347354231209440. doi: 10.1177/15347354231209440.

ABSTRACT

OBJECTIVES: This study reports on the long-term effects of the Better Life After Cancer: Energy, Strength, and Support (BLESS) program, a 12-week social capital-based exercise adherence program for breast cancer survivors (BCS), implemented using a randomized controlled trial design. The study investigated outcomes related to cancer-related fatigue (CRF), quality of life (QOL), physical activity, depression, anxiety, sleep quality, and social capital.

METHODS: Participants who had moderate or greater CRF were randomly assigned to the intervention (n = 24), consisting of supervised and home-based exercise, or the control (n = 26), who received exercise leaflets. Generalized estimating equations models were fitted for the outcome variables. The assessment points were baseline (M1), immediately after completing the intervention at 12 weeks (M2), 1 month (M3), and 6 months post-intervention (M4).

RESULTS: A significant reduction in the total CRF score was found for both groups. We observed a significant time by group effect at M2, indicating a reduction of behavioral/severity CRF scores and a higher increase of physical activity. Also, there was an increase in the QOL score of both groups at M2, M3, and M4, compared to M1. Both groups had reduced anxiety at M3 and M4 compared to M1. The time by group effect for depression, sleep quality and social capital was not statistically significant.

CONCLUSION: This 12-week exercise adherence program improved behavioral/severity CRF and physical activity post-intervention. Both the experimental group and control group showed significant improvements in CRF, QOL, and anxiety domains compared to the baseline, which extended to 6 months post-intervention.

TRIAL REGISTRATION: Korean Clinical Research Information Service (KCT0005763).

The mental health toll of service: an examination of self-reported impacts of public safety personnel careers in a treatment-seeking population

Eur J Psychotraumatol. 2023;14(2):2269696. doi: 10.1080/20008066.2023.2269696. Epub 2023 Nov 15.

ABSTRACT

Introduction: Public safety personnel (PSP), including firefighters, paramedics, and police officers, are exposed to traumatic events as part of their day-to-day jobs. These traumatic events often result in significant stress and increase the likelihood of negative mental health outcomes, including post-traumatic stress disorder (PTSD). The present study sought to develop an in-depth understanding of the lived experiences of PSPs as related to the mental health toll of their service. Through a series of targeted focus groups, Canadian PSP were asked to provide their perspectives on the PTSD-related symptoms that resulted as a by-product of their occupational service. The DSM-5-TR PSTD criteria (A-E) provided a thematic lens to map the self-described symptomatic expression of PSP’s lived experiences.Methods: The present study employed a phenomenological focus-group approach with a treatment-seeking inpatient population of PSP. Participants included PSP from a variety of occupational backgrounds. Using semi-structured focus groups, fifty-one participants were interviewed. These focus groups were audio recorded, with consent, and transcribed verbatim. Using an interpretive phenomenological approach, emergent themes within the data were inductively developed, examined, and connected across individual cases.Results: Utilizing the primary criteria of PTSD (Criteria A-E) outlined by the DSM-5-TR, we identified qualitative themes that included exposure to a traumatic event, intrusion symptoms, avoidance symptoms, negative alterations in mood and cognition, and marked alterations in arousal and reactivity.Conclusion: PSP are exposed to extreme stressors as a daily part of their occupation and are at elevated risk of developing mental health difficulties, including PTSD. In the present study, focus groups were conducted with PSP about the mental health toll of their occupations. Their experiences mapped onto the five primary criteria of PTSD, as outlined by the DSM-5-TR. This study provides crucial descriptive information to guide mental health research aims and treatment goals for PSTD in PSP populations.

Posttraumatic growth EEG neuromarkers: translational neural comparisons with resilience and PTSD in trauma-exposed healthy adults

Eur J Psychotraumatol. 2023;14(2):2272477. doi: 10.1080/20008066.2023.2272477. Epub 2023 Nov 15.

ABSTRACT

Background: Supporting wellbeing beyond symptom reduction is necessary in trauma care. Research suggests increased posttraumatic growth (PTG) may promote wellbeing more effectively than posttraumatic stress disorder (PTSD) symptom reduction alone. Understanding neurobiological mechanisms of PTG would support PTG intervention development. However, most PTG research to-date has been cross-sectional data self-reported through surveys or interviews.Objective: Neural evidence of PTG and its coexistence with resilience and PTSD is limited. To advance neural PTG literature and contribute translational neuroscientific knowledge necessary to develop future objectively measurable neural-based PTG interventions.Method: Alpha frequency EEG and validated psychological inventories measuring PTG, resilience, and PTSD symptoms were collected from 30 trauma-exposed healthy adults amidst the COVID-19 pandemic. EEG data were collected using custom MNE-Python software, and a wireless OpenBCI 16-channel dry electrode EEG headset. Psychological inventory scores were analysed in SPSS Statistics and used to categorise the EEG data. Power spectral density analyses, t-tests and ANOVAs were conducted within EEGLab to identify brain activity differentiating high and low PTG, resilience, and PTSD symptoms.Results: Higher PTG was significantly differentiated from low PTG by higher alpha power in the left centro-temporal brain area around EEG electrode C3. A trend differentiating high PTG from PTSD was also indicated in this same location. Whole-scalp spectral topographies revealed alpha power EEG correlates of PTG, resilience and PTSD symptoms shared limited, but potentially meaningful similarities.Conclusion: This research provides the first comparative neural topographies of PTG, resilience and PTSD symptoms in the known literature. Results provide objective neural evidence supporting existing theory depicting PTG, resilience and PTSD as independent, yet co-occurring constructs. PTG neuromarker alpha C3 significantly delineated high from low PTG and warrants further investigation for potential clinical application. Findings provide foundation for future neural-based interventions and research for enhancing PTG in trauma-exposed individuals.

Association of work-related psychosocial factors and day-to-day home blood pressure variation: the Finn-Home study

J Hypertens. 2023 Nov 16. doi: 10.1097/HJH.0000000000003619. Online ahead of print.

ABSTRACT

OBJECTIVES: Stress, and particularly job strain, has been found to associate with ambulatory blood pressure (BP). Moreover, BP is known to vary between days. One potential over-looked factor underlying this day-to-day BP variation could be work-related psychosocial factors. Thus, we aimed to study the association between job strain, job demands, job control and day-to-day BP variation.

METHODS: The home BP of 754 regularly working participants (mean age 50.9 ± 4.8, women 51%) of the Finn-Home Study was measured twice in the morning and twice in the evening over seven days. Average SBP and DBP were calculated for each day. Work-related psychosocial factors were measured with survey. Multivariable-adjusted generalized linear models were used for statistical analysis.

RESULTS: We found a greater SBP/DBP decrease between weekdays and weekend among participants with high job strain (-1.8 [95% confidence interval, 95% CI, -2.7 to -0.8]/-1.7 [95% CI, -2.3 to -1.1] mmHg) compared to participants with low job strain (-0.7 [95% CI, -1.1 to -0.2]/-0.7 [95% CI, -1.0 to -0.4] mmHg). The participants with high job demands showed a higher BP decrease between weekdays and weekend (-1.4 [95% CI, -2.0 to -0.8]/-1.3 [95% CI, -1.6 to -0.9] mmHg) than the participants with low job demands (-0.5 [95% CI, -1.1 to 0.0]/-0.6 [95% CI, -1.0 to -0.3] mmHg). We did not find BP differences regarding job control.

CONCLUSION: High job strain and high job demands were associated with a greater BP reduction from weekdays to the weekend. Work-related psychosocial factors should be considered when assessing day-to-day BP variation.

Impact of post-implantation syndrome on outcomes in acute type B aortic syndrome patients undergoing endovascular repair

Vasa. 2023 Nov 15. doi: 10.1024/0301-1526/a001102. Online ahead of print.

ABSTRACT

Background: The aim of this study was to explore the impact of post-implantation syndrome (PIS) on prognosis outcomes in individuals with type B acute aortic syndrome (AAS) undergoing thoracic endovascular aortic repair (TEVAR). Patients and methods: Data from type B AAS individuals who underwent TEVAR from January 2014 to April 2021 were retrospectively reviewed. Study subjects were divided into PIS and non-PIS (nPIS) groups and postoperative clinical outcomes were analyzed. Results: Our study cohort of 74 individuals with type B AAS included 40 aortic dissection (AD), 30 intramural hematoma (IMH), 4 penetrating aortic ulcer (PAU). The incidence of PIS was 14.9%. No statistically significant differences were found in baseline characteristics. The left subclavian artery (LSCA) reconstruction was performed more frequently among the PIS group (45.5% vs 9.5%, p=.008). Major adverse events (MAE) tended to be more frequent in the PIS group, but the difference was not significant (27.3% vs 22.2%, p=.707). At 2-year follow-up, results were comparable between the two groups. Kaplan-Meier analysis showed that PIS was not associated with a higher incidence of mortality, endoleak, new-onset AD, or stroke. A baseline neutrophil-to-lymphocyte ratio (NLR) >10.3 was associated with greater incidence of MAE. In individuals with IMH, better aortic remodeling evaluated by lower total aortic diameter/true lumen diameter (TAD/TLD) was achieved in the nPIS group (1.23±0.10 vs 1.43±0.07, p<.001), and a TAD/TLD ratio >1.32 was associated with significantly more MAE. Cox multivariate regression analysis also showed that a postoperative TAD/TLD ratio >1.32 was an independent risk factor for MAE (OR, 11.36; 95% CI, 1.53-84.26; p=.017). Conclusions: PIS was associated with a trend toward a higher incidence of MAE after TEVAR. In individuals with IMH, a TAD/TLD ratio >1.32 was an independent predictor of postoperative MAE.

Exploring Vaccination Sentiments: A Population-Centric Examination

J Prim Care Community Health. 2023 Jan-Dec;14:21501319231210615. doi: 10.1177/21501319231210615.

ABSTRACT

Vaccine hesitancy has, for a considerable time, been a significant risk to global health. As an integral part of disease prevention, vaccines have become a public health matter which is often debated among the community in spite of proven scientific evidence of their efficiency. A questionnaire was designed to evaluate the perception and knowledge of a population and compare it with behavior in order to assess a demographic within a sample population of 245 individuals selected at random within the United States, Here, we aim to clarify the difference between vaccine opinion among the general public as compared to vaccination status. Chi-squared analysis was done with the categorical data showing a statistically significant result when comparing parents versus non-parents, and Asian/Asian Americans against other ethnicities. All other comparisons were statistically insignificant. When looking at participant responses, PCPs did not discuss vaccines at all with 32% of the sample. The need for PCPs to provide educational information to certain ethnicities may play an important role in public health.
