ABSTRACT

Vein diseases are one of the most common civilization diseases. The most advanced form chronic venous insufficiency are venous leg ulcers. The study included 40 patients, 20 male (50%) and 20 female (50%) in age between 52 and 88 years (mean age: 68.00 ± 8.55 years) with venous leg ulcers lasting 12.50 ± 5.45 months. Patients were distributed randomly in a double-blind study into two equal groups including 20 patients each (group 1-polarized light therapy and group 2-sham exposure). Patients from both groups received routine pharmacological treatment, specialistic medical dressings and compression therapy. In addition, patients were exposed to a cycle of polarized light therapy procedures or to sham exposures (30 procedures performed in two series of 15 procedures). Wound surface area was evaluated by computerized planimetry and pain intensity was assessed with the use of Visual Analog Scale (VAS) before and after therapy (2.5 months). The analysis showed a statistically significant reduction of surface ulcers area between groups 1 and 2. The median (IQR) size of wounds in group 1 was 2.4 (1.95-2.9) cm², in group 2; 2.8 (2.6-3.1) cm² (p = 0.038). The level of pain (VAS) after treatment was assessed in group 1, median (IQR): 2 (2-3) points, in group 2 4.5 (4-5) points; and the observed difference was also statistically significant (p < 0.001). In group 1, after treatment, the area of ulcers decreased-median (IQR): 33.05 (28.7-41.48) %, in group 2 by 18.99 (15-24.4) % (p < 0.001). In group 1, the pain intensity measured using the VAS scale decreased with a median (IQR): 71.42 (61.25-71.42) %, in group 2: 37.5 (28.57-50) % (p < 0.001). Complex therapy with polarized light therapy added to standard care was more effective than standard care alone in reducing of ulcers surface area and intensity of pain ailments in patients with chronic venous leg ulcers.

ABSTRACT

PURPOSE: Social rehabilitation of aggression following an Acquired Brain Injury (ABI) is critically important for persons with ABI due to increased vulnerability of criminal behaviour related to post-injury changes in functioning. This review presents findings from studies that evaluated aggression interventions in both community and forensic populations of people with ABI.

METHODS: We searched PsycINFO, EMBASE, SocINDEX, CINAHL and Medline databases for studies published between 1^st January 2000 and 15^th October 2023.

RESULTS: There were 15 studies (14 community-based, one forensic) that met inclusion criteria. Pharmacological management (6) was largely ineffective and anger management interventions (6) presented with inconsistent effectiveness. Emotion regulation (1) may be effective for externalised aggression. Both mindfulness and transcranial direct current stimulation (1) were effective, and the results of a forensic peer group approach (1) were not tested for statistical significance. There was variability in the measurement of aggression, injury severity, and cognitive impairment.

CONCLUSIONS: Whilst community interventions for aggression in persons with ABI are prevalent, findings for effectiveness have been mixed and there is a paucity of evaluated interventions in forensic samples. Further research is needed to unravel the complex interplay of factors contributing to aggression and develop effective social rehabilitation for persons with ABI.

ABSTRACT

Spinal bone lesions encompass a wide array of pathologies, spanning from benign abnormalities to aggressive malignancies, such as diffusely localized metastases. Early detection and accurate differentiation of the underlying diseases is crucial for every patient’s clinical treatment and outcome, with radiological imaging being a core element in the diagnostic pathway. Across numerous pathologies and imaging techniques, deep learning (DL) models are progressively considered a valuable resource in the clinical setting. This review describes not only the diagnostic performance of these models and the differing approaches in the field of spinal bone malignancy recognition, but also the lack of standardized methodology and reporting that we believe is currently hampering this newly founded area of research. In line with their established and reliable role in lesion detection, this publication focuses on both computed tomography and magnetic resonance imaging, as well as various derivative modalities (i.e. SPECT). After conducting a systematic literature search and subsequent analysis for applicability and quality using a modified QUADAS-2 scoring system, we confirmed that most of the 14 identified studies were plagued by major limitations, such as insufficient reporting of model statistics and data acquisition, a lacking external validation dataset, and potentially biased annotation. Although we experienced these limitations, we nonetheless conclude that the potential of these methods shines through in the presented results. These findings underline the need for more stringent quality controls in DL studies, as well as model development to afford increased insight and progress in this promising novel field.

ABSTRACT

BACKGROUND: Pain management of sedated and ventilated patients in intensive care units lacks consistency.

OBJECTIVES: To investigate nurses’ training, governance, practices, knowledge and attitudes relating to pain management in consideration of published guidelines and explore nurses’ perspectives.

METHODS: A survey design, using an online questionnaire with free text responses, was employed. Quantitative and qualitative data from nurses working across different hospitals were collated and saved on Qualtrics platform. Quantitative data were analysed non-parametrically and narrative responses thematically. CROSS and SRQR reporting guidelines were adhered to.

OUTCOME MEASURES: Demographics, training, governance, clinical practice, knowledge, and attitudes.

RESULTS/FINDINGS: 108 nurses participated with ninety-two completed surveys analysed. Analgesia was used to complete nursing tasks regardless of comfort needs (n = 49, 53.3 %). Changes in vital signs prompted opioid administration (n = 48, 52.1 %). Choice of analgesia depended on doctor’s preference (n = 63, 68.5 %). Non-opioid therapy was administered before opioids (n = 42, 45.7 %). Sedatives were used to alleviate agitation(n = 50,54.3 %). No statistically significant difference in nurses’ knowledge existed between hospitals. Weak positive relationship: r = [0.081], p = [0.441] between “knowledge scores” and “years of ICU experience” and weak negative relationship r = [-0.119], p = [0.260] between “knowledge scores” and “hours of clinical practice” was detected. Lack of training, resources, policies, high patient acuity and casual employment were acknowledged barriers to pain management. Two overarching themes emerged from narrative responses: “Pain assessment, where is it?” And “Priorities of critical illness.”

CONCLUSION: The study uncovered pain management situation and examined nurses’ demographics, training, governance, practices, knowledge and attitudes. Narrative responses highlighted barriers to pain management.

IMPLICATIONS FOR CLINICAL PRACTICE: Health organisations should provide education, institute governance and develop policies to inform pain management. Nurses’ role encompasses updating knowledge, adhering to interventions and overcoming biases. This subsequently manifests as improvement in patient outcomes.

ABSTRACT

BACKGROUND: Inflammation plays a crucial role in tumor development and progression, with inflammatory markers showing promise in predicting cancer prognosis. However, their significance in muscle-invasive bladder cancer (MIBC), especially in the context of neoadjuvant chemotherapy (NAC), remains poorly understood. This study aims to evaluate the prognostic utility of neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), systemic immune inflammation index (SII), and derived neutrophil-to-lymphocyte ratio (dNLR) for overall survival (OS) in bladder cancer (BC) patients undergoing radical cystectomy (RC) in the NAC era.

PATIENTS AND METHODS: A retrospective review analyzed prospectively-collected data from our institutional BC registry, covering patients with MIBC undergoing RC with curative intent from March 1st, 2016, to December 31st, 2022. Blood samples were collected preoperatively to calculate NLR, PLR, SII, and dNLR. OS was defined from surgery to last follow-up or death. Statistical analyses included ROC curves, Kaplan-Meier Curves, and Cox proportional hazards regression models.

RESULTS: A total of 187 patients with median duration follow-up of 14.7 month were included in this study and 50.8% experienced death. NAC was administered in 50.3% of cases. The ideal cut-off for dichotomizing NLR, PLR, SII, and dNLR was 1.76, 104.30, 410.66, and 1.30, respectively. In multivariable analysis each of these biomarkers emerged as an independent prognostic factor for predicting OS. The results showed a correlation between higher NLR, PLR, SII, and dNLR levels and a deterioration in OS.

CONCLUSION: Elevated values of these inflammatory markers indicate poorer survival, highlighting their potential as indicators of disease aggressiveness. Identifying patients with elevated markers can help healthcare providers personalize treatment strategies, improving patient outcomes and survival rates.

ABSTRACT

INTRODUCTION: The renin-angiotensin system (RAS) has been demonstrated to modulate cell proliferation, desmoplasia, angiogenesis and immunosuppression. We examined the association of RAS inhibitors (RASi)-namely angiotensin converting enzyme inhibitors (ACEi) and angiotensin receptor blockers (ARB)-with neoadjuvant chemotherapy (NAC) for muscle-invasive bladder cancer (MIBC) preceding radical cystectomy (RC).

PATIENTS AND METHODS: We retrospectively investigated concurrent RASi use with NAC prior to RC in 302 patients with MIBC from 3 academic institutions. Outcomes included pathologic complete response (pCR) and overall survival (OS). Pathologic features, performance status (PS), clinical stage, type/number of cycles of NAC, and toxicities were collected.

RESULTS: Overall pCR rate was 26.2% and 5-year OS was 62%. Concurrent ACEi intake with NAC approached significance for association with pCR (odds ratio [OR] = 1.71; 95% CI, 0.94-3.11; P = .077). Patients with cT3/4N0-N1 disease receiving ACEi had higher pCR rates (30.8% vs. 17.7%, P = .056) than those not on ACEi. Female sex had a statistically significant favorable interaction for pCR with ACEi intake (P = .044). ACEi intake was not associated with OS, while pCR, PS and lower clinical stage were significantly associated with improved OS.

CONCLUSION: ACEi intake is potentially associated with increased pCR in patients with MIBC receiving NAC prior to RC, and this association is more pronounced in patients with higher clinical stage of disease at the initiation of therapy and female sex. Our data suggest the potential relevance of the RAS as a therapeutic target in aggressive MIBC.

ABSTRACT

There is a lack of knowledge about the health consequences of politically initiated forced permanent rehousing (FPR) of residents in social housing areas. This study investigates if FPR is associated with the contact frequency with general practitioner (GP) and the proportion of residents who use antidepressants. The study included 432 rehoused residents matched 1:2 with remaining residents and residents from a comparable neighbouring area without exposure to rehousing. For GP contact frequency, we conducted a difference-in-difference analysis while the proportion of residents who used antidepressants was investigated through descriptive statistics. We found high GP contact frequency in the three groups, but no significant differences. Further, we found a low proportion of residents who used antidepressants in all groups, but a small increase from baseline to follow-up. Our results thus suggest that FPR neither affected the rehoused residents’ GP contact frequency nor the proportion who used antidepressants.

ABSTRACT

On November 4, 2008, Barack Obama was elected the first Black President of the United States. His campaign and electoral win served as a symbol of hope for a more just future, fostering an “Obama effect” that appears associated with improved well-being among non-Hispanic (NH) Black communities. Situating the Obama election within the symbolic empowerment framework, we consider the potentially protective role of the Obama election on NH Black fetal death, an important but understudied measure of perinatal health that has stark racial disparities. Using restricted-use natality files from the National Center for Health Statistics, we proxy fetal death using the male twin rate (number of twins per 1000 male live births). Male twins have a relatively high risk of in utero selection that is sensitive to maternal and environmental stressors, making the twin rate an important marker of fetal death. We then estimate interrupted time-series models to assess the relation between the Obama election and male twin rates among NH Black births across monthly conception cohorts (February 2003-October 2008). Greater-than-expected male twin rates signal less susceptibility to fetal loss. Results indicate a 4.5% higher male twin rate among all NH Black cohorts exposed in utero to the Obama election, after accounting for historical and NH white trends (p < 0.005). The greater-than-expected rates concentrated among births conceived in the months preceding Obama’s nomination at the Democratic National Convention and Obama’s presidential win. These results suggest a salutary perinatal response to election events that likely reduced NH Black fetal loss. They also indicate the possibility that sociopolitical shifts can mitigate persisting NH Black-NH white disparities in perinatal health.

ABSTRACT

PURPOSE: This study aims to introduce modified fixed field volumetric modulated arc therapy (MF-VMAT) which manually opened the field size by fixing the jaws and comparing it to the typical planning technique, auto field volumetric modulated arc therapy (AF-VMAT) in cervical cancer treatment planning.

METHODS AND MATERIALS: Previously treated twenty-eight cervical cancer plans were retrospectively randomly selected and replanned in this study using two different planning techniques: AF-VMAT and MF-VMAT, resulting in a total of fifty-six treatment plans. In this study, we compared both planning techniques in three parts: (1) Organ at Risk (OARs) and whole-body dose, (2) Treatment plan efficiency, and (3) Treatment plan accuracy.

RESULTS: For OARs dose, bowel bag (p-value = 0.001), rectum (p-value = 0.002), and left femoral head (p-value = 0.001) and whole-body (p-value = 0.000) received a statistically significant dose reduction when using the MF-VMAT plan. Regarding plan efficiency, MF-VMAT exhibited a statistically significant increase in both number of monitor units (MUs) and control points (p-values = 0.000), while beam-on time, maximum leaf travel, average maximum leaf travel, and maximum leaf travel per gantry rotation were statistically significant decreased (p-values = 0.000). In terms of plan accuracy, the average gamma passing rate was higher in the MF-VMAT plan for both absolute dose (AD) (p-value = 0.001, 0.004) and relative dose (RD) (p-value = 0.000, 0.000) for 3%/3 and 3%/2 mm gamma criteria, respectively.

CONCLUSION: The MF-VMAT planning technique significantly reduces OAR doses and decreases the spread of low doses to normal tissues in cervical cancer patients. Additionally, this planning approach demonstrates efficient plans with lower beam-on time and reduced maximum leaf travel. Furthermore, it indicates higher plan accuracy through an increase in the average gamma passing rate compared to the AF-VMAT plan. Consequently, MF-VMAT offers an effective treatment planning technique for cervical cancer patients.

ABSTRACT

OBJECTIVES: Grotta-Riparo di Uluzzo C (Apulia, southern Italy) is a pivotal site for investigating the evolution of the Middle Paleolithic and the earliest phases of the Upper Paleolithic in southern Italy, as the extensive stratigraphic record of this site includes a thick Mousterian sequence followed by the Uluzzian. Here, we investigate the taxonomic affinity of seven unpublished deciduous human teeth retrieved from the site of Uluzzo C in 1960.

MATERIALS AND METHODS: The teeth are represented by seven plaster dental casts, which are housed at the Museo Civico di Paleontologia e Paletnologia in Maglie (Lecce, Apulia). The location of the original specimens remains unknown, rendering these casts the only human remains evidence yielded by Uluzzo C to date. Based on occlusal-view photographs and digital models of the casts, we examined the external morphology and morphometry of the teeth, comparing them to Homo sapiens and H. neanderthalensis samples. Through geometric morphometric methods and statistical analyses, we analyzed the crown outline of the deciduous molars.

RESULTS: The teeth show morphological and morphometric features that are variably found in H. neanderthalensis, H. sapiens, or both. Specifically, crown outline analysis shows that all molars fall within H. neanderthalensis variability, except for Uluzzo 853 (lower right deciduous first molar), which falls within H. sapiens variability.

DISCUSSION: This study provides the first taxonomic assessment of the hominin teeth from Uluzzo C. The results contribute additional insights into the Paleolithic peopling of southern Italy during a crucial period marked by the persistence of post-Tyrrhenian Neanderthal techno-complexes and the arrival of H. sapiens.
