Authors: Nagy Attila Csaba , Tóth Ágnes , Bak Natália , Ulambayar Battamir , Ghanem Amr Sayed , Sztanek Ferenc
Published: November 2024

Background: Sodium–glucose co-transporter 2 (SGLT-2) inhibitors, initially designed for type 2 diabetes, promote glucose excretion and lower blood glucose. Newer analogs like empagliflozin and dapagliflozin improve cardiovascular outcomes through mechanisms other than glycemic control, including blood pressure reduction and anti-inflammatory effects. Given the high cardiovascular risk present in diabetes, our study aims to emphasize the cardioprotective benefits of SGLT-2 inhibitors as a preventive therapy for heart failure (HF) in high-risk T2DM patients. Methods: Using data from 2542 patients identified by the ICD-10 E11 code from 2016 to 2020, this longitudinal study excluded those with E10 codes or those undergoing insulin treatment to focus on non-insulin-dependent T2DM. a multiple logistic regression model assessed HF incidence while adjusting for demographics and HbA1c. Results: SGLT-2 inhibitor use significantly lowered the odds of heart failure events (OR = 0.55, 95% CI: 0.31–0.99, p = 0.046), with a significant difference by gender (OR = 0.45, 95% CI: 0.28–0.71, p = 0.001) and eGFR (OR = 0.98, 95% CI: 0.97–0.99, p = 0.004). Conclusions: The real-world data highlight SGLT-2 inhibitors as promising for HF prevention and broader cardiometabolic health in T2DM, with potential value in managing complex comorbid profiles.

Published: November 2024

Background and aim: Patients with non-infarct-related artery chronic total occlusion (non-IRA CTO) found during percutaneous coronary intervention (PCI) in acute coronary syndromes (ACSs) are not rare and have worse clinical outcomes. We aimed to analyze their long-term clinical outcomes in regard to clinical characteristics, revascularization strategies, and adherence to medical therapy. Patients and methods: The dual-center ACS registry of patients treated from Jan 2017 to May 2023 was used to identify 1950 patients with timely PCI in ACS who survived to discharge with documented adequate demographic, clinical, and angiographic characteristics, treatment strategies, and medical therapy adherence during a median follow-up time of 49 months. Results: There were 171 (9%) patients with non-IRA CTO. In comparison to patients without non-IRA CTO, they were older, with more diabetes mellitus (DM), higher Syntax scores (median 27.5 vs. 11.5), and lower left ventricular ejection fraction (LVEF) at discharge (median LVEF 50% vs. 55%). There was also a lower proportion of patients with high adherence to medical therapy (32% vs. 46%). Patients with non-IRA CTO had significantly higher cardiovascular mortality during follow-up (18% vs. 8%, RR 1.87, 95% CI 1.27–2.75). After adjusting for relevant clinical and treatment characteristics in a multivariate Cox regression analysis, only lower LVEF, worse renal function, the presence of DM, and lower adherence to medical therapy were independently associated with higher cardiovascular mortality during follow-up, with low adherence to medical therapy as the strongest predictor (RR 3.18, 95% CI 1.76–5.75). Time to cardiovascular death was significantly lower in patients who did not receive non-IRA CTO revascularization, although CTO revascularization did not show independent association with survival in the multivariate analysis. Conclusions: Patients with non-IRA CTO found during ACS treatment have more unfavorable clinical characteristics, worse adherence to medical therapy, and higher cardiovascular mortality. They need a more scrutinized approach during follow-up to increase adherence to optimal medical therapy and to receive revascularization of the non-IRA CTO whenever it is clinically indicated and reasonably achievable without excess risks.

Published: November 2024

Background: Patients with recreational drug and ethanol poisoning often present with reduced consciousness, coma, or disorientation. It is often unclear if there was recent head trauma. Algorithms to perform cranial computed tomography (cCT) like the Canadian CT Head Rule (CCHR), the National Emergency X-Radiography Utilization Study Head CT Decision Instrument (NEXUS DI), or the New Orleans Criteria (NOC) exist for patients with head trauma. It is unclear whether these algorithms can be applied to this patient collective. Methods: This is a retrospective data analysis of patients admitted to our emergency department with drug or ethanol poisoning in 2019. Minors < 16 years were excluded. The primary outcome was fracture/bleeding in cCT, the secondary outcome was neurosurgical intervention. These results were calculated: 1. Sensitivity and negative predictive value (NPV) of the CCHR, NEXUS DI, and NOC. 2. Uni- and multivariate analysis of risk factors for critical findings. 3. The Munich cCT Rule sensitivity and NPV. Results: A total of 420 patients were included. cCT was performed in 120 patients. Eight patients had fracture/bleeding in cCT, two required neurosurgical intervention. The number of patients at risk, sensitivity, and NPV for critical cCT findings were as follows: CCHR 57/25%/98.3%, NEXUS DI 239/100%/100%, NOC 420/100%/100%. The sensitivity and NPV for neurosurgical intervention were as follows: CCHR 50%/99.7%, NEXUS DI 100%/100%, NOC 100%/100%. In univariate analysis, these findings correlated significantly with the following critical findings: accident, injury, injury above clavicle, head wound, anisocoria, ethanol in serum > 2 g/L, hypotension, drug ingestion, GCS < 8, focal neurological deficit, age > 60, and cerebellar symptoms. Via chi-square recursive partitioning analysis, we created the Munich cCT Rule which is positive for intoxicated patients if both an accident and an ethanol level > 2 g/L are present. This identified 70 patients at risk. It excluded fracture/bleeding and neurosurgical intervention with a sensitivity and NPV of 100%. Conclusions: Fracture/bleeding in cCT in intoxicated patients is rare. Performing unnecessary cCTs should be avoided. The Munich cCT Rule for patients with recreational drug and ethanol poisoning may help rule out critical findings and is superior to the NEXUS DI and NOC. It also has a 100% sensitivity which the CCHR (25%) is lacking.

Published: November 2024

Background: For patients undergoing abdominal surgery, postoperative pulmonary complications (PPCs) are a major source of morbidity and mortality. The use of point-of-care ultrasonography (POCUS), and specifically POCUS of the lungs, has seen many advancements in recent years. Objectives: We hypothesize that perioperative lung ultrasonography can be used as a predictor for PPCs. Methods: In a Single, 1000 beds, trauma level I medical center, patients presenting for elective intra-abdominal surgery with no severe pulmonary or cardiac diseases were evaluated preoperatively with a standardized 12-point lung ultrasound exam. A second identical exam was performed after surgery in the post-anesthesia care unit. PPCs were also documented. All lung ultrasound exams were presented to a blinded researcher and a lung ultrasound score (LUS) was calculated. Statistical analysis comparing pre- and postoperative LUS and PPC scores were performed. Results: A total of 61 patients were evaluated. The pre-surgery median LUS was 0 (in the range of 0–6) and the post-surgery median LUS was 3 (in the range of 0–14). The pre- to postsurgical LUS delta was 3.4 (standard deviation of 3.3). A postoperative LUS of 6 or more was defined as “high.” A High LUS did not correlate with prolonged post-anesthesia care unit or hospital stay, prolonged oxygen support, or number of desaturation events. Conclusion: For elective abdominal surgery in relatively healthy patients, preoperative LUS usually begins at a normal level and becomes worse after general anesthesia. However, this difference in LUS is not significantly associated with clinically relevant postoperative pulmonary complications such as prolonged oxygen therapy, pneumonia, and noninvasive or invasive mechanical ventilation. Trial registration: Clinicaltrials.gov identifier: NCT05502926. Summary: This paper explores the use of point-of-care ultrasonography as a predictor for postoperative pulmonary complications. The findings suggest that while the lung ultrasound score worsens with general anesthesia, the differences are not significantly associated with postoperative pulmonary complications.
The Efficacy of Multiwavelength Red and Near-Infrared Transdermal Photobiomodulation Light Therapy in Enhancing Female Fertility Outcomes and Improving Reproductive Health: A Prospective Case Series with 9-Month Follow-Up
Authors: Phypers Ruth , Berisha-Muharremi Venera , Hanna Reem
Published: November 2024

Background/Objectives: Female infertility due to unexpected causes exhibits a great challenge for both clinicians and women who are trying to conceive. The present clinical case series study aimed to evaluate the efficacy of multiple wavelengths of red and near-infrared (NIR) laser photobiomodulation (PBM) for increasing the potential of fertility in women and improving reproductive health in unexplained infertility issues. The objectives were to assess the following: (1) any adverse effects; (2) the possibility of producing an effective PBM protocol; (3) and healthy live birth. The inclusion criteria were to related to females who failed to conceive naturally beyond two years, multiple miscarriages, molar pregnancy, non-viable embryos from in vitro fertilisation (IVF) cycles, and failure to complete successful implantation of viable pre-implantation genetic tested (PGT-A) embryos. Methods: Case series of three female subjects with unexplained age-related infertility issues, which included a failure to conceive naturally beyond two years, multiple miscarriages, molar pregnancy, non-viable embryos from IVF cycles, and failure to complete successful implantation of viable pre-implantation genetic tested (PGT-A) embryos. In each case, previous conditions were recorded and then compared with outcomes after the patient received a course of PBM treatments. In every case, fertility outcomes improved. Three cases resulted in a full-term pregnancy and the birth of a healthy baby. PBM treatments were given at weekly and/or at two-week intervals using IR and NIR wavelengths between 600 nm and 1000 nm in the lead up to natural conception, IVF oocyte retrieval, blastocyst/embryo implantation, and/or the production of viable embryos. Results: In every case, fertility outcomes improved. Improvements in reproductive health outcomes in each case give reason to suggest that PBM may help to improve unexplained age-related infertility. Conclusions: Our study demonstrated that multiwavelength of red and NIR PBM with either an LED or laser, or a combination, improved female fertility and reproductive health and contributed to healthy live births in females diagnosed with unexplained age-related infertility. Extensive studies with robust data are warranted to validate our PBM dosimetry and treatment protocols. Moreover, understanding the genetic and phenotype biomarkers is important to standardise a range of PBM light dosimetry.

Published: November 2024

Background: Pulmonary arterial elastance (Ea) is a helpful parameter to predict the risk of acute postoperative right ventricular failure (RVF) after left ventricular assist device (LVAD) implantation. A new method for calculating Ea, obtained by the ratio between transpulmonary gradient and stroke volume (EaB), has been proposed as a more accurate measure than the Ea obtained as the ratio between pulmonary artery systolic pressure and stroke volume (EaC). However, the role of EaB in predicting acute RVF post-LVAD implantation remains unclear. Methods and Results: A total of 35 patients who underwent LVAD implantation from 2018 to 2021 were reviewed in this retrospective analysis. Acute RVF after LVAD implantation occurred in 12 patients (34%): 5 patients with moderate RVF (14% of total) and 7 patients with severe RVF. The EaB was not significantly different between the “severe RVF” vs. “not-severe RVF” groups (0.27 ± 0.04 vs 0.23 ± 0.1, p < 0.403). However, the combination of arterial elastance and central venous pressure was significantly different between the “not-severe RVF” group (central venous pressure < 14 mmHg and EaC < 0.88 mmHg/mL or EaB < 0.24 mmHg/mL; p < 0.005) and the “severe RVF” group (central venous pressure > 14 mmHg and EaC > 0.88 mmHg/mL or EaB > 0.24 mmHg/mL; p < 0.005). Conclusions: Ea is a reliable parameter of right ventricular afterload and helps discriminate the risk of acute RVF after LVAD implantation. The combined analysis of Ea and central venous pressure can also risk stratify patients undergoing LVAD implantation for the development of RVF.

Published: November 2024

Background/Objectives: Transthyretin amyloid (ATTR) cardiomyopathy mimics left ventricular hypertrophy (LVH) and has been identified as a specific cause of heart failure (HF). The aim of this study was to assess the prevalence of ATTR among patients presenting to the Emergency Department (ED) with acute HF (AHF) and LVH and explore their clinical characteristics and outcomes. Methods: Of 127 AHF patients with LVH, 95 completed the diagnostic protocol, which included monoclonal paraprotein testing and technetium-99 m pyrophosphate scintigraphy. Patients were followed for 6 months, and adverse events, including mortality and HF-related hospitalizations, were recorded. Results: ATTR was diagnosed in 8.4% of patients. The mean left ventricular ejection fraction (EF) was 46 ± 7% in ATTR subjects, with 25% classified as HF with reduced EF, 37.5% HF with mildly reduced EF, and 37.5% HF with preserved EF. N-terminal pro b-type natriuretic peptide (NT-proBNP) and high sensitivity troponin T (hs-TnT) were higher in ATTR compared to the non-ATTR group [NT-proBNP: 5863 (6519–12382) pg/mL versus 3586 (1393.5–6322) pg/mL, p = 0.007; hs-TnT: 35.9 (47.9–83.8) pg/mL versus 30.0 (19.4–49.5) pg/mL, p = 0.0006]. During follow-up, twenty-three patients from the cohort died: six in the ATTR and seventeen in the non-ATTR group. The estimated survival rate was significantly lower in ATTR versus non-ATTR patients (log-rank p < 0.0001). Conclusions: In this cohort of AHF patients with LVH presenting to the ED, ATTR cardiomyopathy was detected in 8.4%. Using routinely used cardiac biomarkers and basic echocardiography allows for the raising of suspicion of the disease from the ED setting, potentially facilitating earlier diagnosis in this population.

Published: November 2024

Background and hypothesis: Renal anemia is linked to a decreased lifespan of red blood cells. The factors influencing red blood cell lifespan (RBCLS) in peritoneal dialysis patients, particularly the connection between inflammation and RBCLS, are still not well understood. This cross-sectional study was conducted to investigate these relationships. Methods: Patients who had been undergoing peritoneal dialysis for more than 3 months were selected for this study. The carbon monoxide exhalation method was used to detect the life span of red blood cells. The patients were then divided into two groups based on whether the RBCLS was shorter than 75 days. General information, anemia-related indicators, and other laboratory indicators along with their treatment were compared between the two groups. The different indicators were then included in a logistic regression analysis to identify independent risk factors that influence the shortening of RBCLS. Results: A cohort of 59 peritoneal dialysis patients was examined, revealing a median RBCLS of 88 days. Of these patients, 39 exhibited a normal RBCLS, while 20 had a shortened lifespan. A comparison of the two groups indicated that patients with a shorter RBCLS exhibited lower levels of PD vintage (29.5 vs. 56.0, p = 0.031), albumin (34.62 ± 3.01 vs. 37.41 ± 3.60, p = 0.004), cholesterol (4.02 ± 0.54 vs. 4.55 ± 1.21, p = 0.026), and low-density cholesterol (2.19 ± 0.43 vs. 2.75 ± 0.87, p = 0.002), and a higher neutrophil-to-lymphocyte ratio (NLR) (3.05 vs. 2.61, p = 0.026) compared to those with a normal RBCLS. The logistic regression results indicated that PD vintage (OR 0.976, CI 0.958–0.999), albumin (OR 0.668, CI 0.514–0.867), low-density lipoprotein cholesterol (OR 0.046, CI 0.002–0.953), and NLR (OR 1.792, CI 1.016–3.162) were identified as independent risk factors influencing the shortening of RBCLS. Conclusion: Hypoalbuminemia, low LDL, and high NLR in peritoneal dialysis patients are identified as independent risk factors associated with a shortened RBCLS. Key learning points: RBCLS is reduced in both peritoneal dialysis and hemodialysis patients. The neutrophil-to-lymphocyte ratio (NLR) in peripheral blood, a simple and readily available laboratory indicator, can reflect the inflammatory status. This study adds: Nutritional status (albumin and LDL) and inflammatory status (NLR) are significant factors that impact the lifespan of red blood cells in peritoneal dialysis patients. Potential impact: This study presents novel findings on the relationship between chronic inflammation and RBCLS in patients with chronic kidney disease, highlighting the need for additional research in this area.

Published: November 2024

Objectives: We aimed to examine the relationship of Dopamine transporter (DAT) and vesicular monoamine transporter (VMAT-2) gene and protein levels with psychic experiences and other clinical parameters in individuals with Methamphetamine Use Disorder (MUD). Methods: This study included 50 males diagnosed with MUD and 50 males as a smoking control (SC) and nonsmoking control (NSC). Community Assessment of Psychic Experiences (CAPE) was administered to patients and controls; Addiction Profile Index, Treatment Motivation Questionnaire, and Substance Craving Scale were administered only to the patient group. DAT and VMAT2 gene and protein levels were determined in blood obtained from the controls and patient groups. Results: CAPE positive, depressive, total, and distress scores were significantly higher in the patient group. DAT protein level and VMAT2 gene and protein levels were lower in the patient group compared to the controls. The DAT gene expression level was higher in the patient group compared to the controls. There was no correlation between any clinical variables and expression levels. A low VMAT2 gene expression level could diagnose MUD with a 5% probability when NSCs were used as a reference. A high DAT gene expression level could diagnose tobacco use disorder (TUD) with a 99.9% probability when NSCs were used as a reference. Conclusions: The patient group showed more psychic experiences than healthy people. The low expression of the VMAT2 gene was identified as a predictor of MUD, while the high expression of the DAT gene was predictive of TUD.

Aim: This study sought to evaluate the effectiveness of lactate/albumin ratio for ICU mortality prediction in a large cohort of patients with severe Coronavirus Disease-2019 (COVID-19) admitted to an intensive care unit (ICU). Methods: This is a single-center retrospective cohort study of prospectively collected data derived from the COVID-19 dataset for all critically ill patients admitted to an academic ICU. Data were used to determine the relation between lactate/albumin ratio and other laboratory parameters measured on the first day of the ICU stay and to evaluate the prognostic performance for ICU mortality prediction. Results: A total of 805 ICU patients were included, and the median age (IQR) was 67 (57–76) years, with 68% being male. ICU mortality was 48%, and the median lactate/albumin ratio was 0.53 (0.39–0.59). A survival analysis showed that patients with higher lactate/albumin ratio values had significantly lower survival rates (Log Rank p < 0.001). A multivariable analysis revealed that the lactate/albumin ratio was an independent risk factor for ICU mortality with a hazard ratio of 1.39 (CI: 1.27–1.52). The lactate/albumin ratio showed a receiver operating characteristics area under the curve (ROC-AUC) value to predict ICU mortality significantly higher than that of lactate alone (0.71 vs. 0.68, DeLong test p < 0.001). The optimal lactate/albumin ratio cut-off for predicting ICU mortality was 0.57, with 63% sensitivity and 73% specificity. A subgroup analysis revealed that the lactate/albumin ratio was significantly associated with mortality across different patient groups, including age and sex categories, and those with or without hypertension and coronary heart disease. Conclusions: Lactate/albumin ratio is a reliable prognostic marker in critically ill COVID-19 patients and could predict ICU mortality more accurately than lactate alone.
A Meta-Analysis of Timing of Complete Revascularization in Patients with ST-Elevation Myocardial Infarction
Authors: Kuzemczak Michał , Mahmoud Abdelrahman , Abdellatif Mohammed A. R. , Alkhalil Mohammad
Published: November 2024

Background: Recent randomized clinical trials (RCTs) of STEMI patients with multi-vessel disease (MVD) reported potential superiority of immediate (ICR) vs. staged complete revascularization (SCR). Inherently, the risk of procedural MI is less likely to be detected in ICR patients, and this may have influenced the results. Recently published meta-analyses encompassed observational studies without including STEMI data from the BioVasc trial. The aim of this meta-analysis was to perform an updated comparison of the two strategies in STEMI patients with MVD. Methods: Electronic databases were searched from their inception till August 2024 to identify RCTs assessing CR timing in STEMI patients with MVD. Only studies with an endpoint involving major adverse cardiovascular events (MACE) were included. Results: Six RCTs totaling 2023 patients were included in the analysis. The median time to staged PCI was 19 days. The incidence of MACE (as defined by each study’s protocol) was comparable between the two strategies [RR 0.86, 95% CI (0.58 to 1.27)]. There was also no difference in the risk of non-procedural MI [RR 0.91, 95% CI (0.49–1.67)], death [RR 1.47, 95% CI (0.89–2.44)] and cardiovascular death [RR 1.53, 95% CI (0.79–2.98)]. There was a significant 40% reduction in unplanned revascularization in patients undergoing ICR versus SCR [RR 0.60 (0.40 to 0.89), p = 0.01]. Conclusions: ICR reduced the risk of unplanned revascularization compared to SCR but had a comparable effect on MACE, death, cardiovascular death and non-procedural MI. Both strategies are safe in managing patients with acute MI and MVD.

Published: November 2024

Background/Objectives: Increased lipoprotein(a) [Lp(a)] level is associated with elevated possibility of atherosclerosis progression. SYNTAX score enables to grade the anatomy of coronary arteries. To identify the impact of increased Lp(a) level on SYNTAX score in individuals with acute myocardial infarction (AMI). Methods: In our analysis, we enrolled 173 consecutive adult patients hospitalized for AMI in a tertiary cardiology center from December 2022 to August 2023. Patient characteristics were compared for patients with SYNTAX score ≥ 23 (64 patients) and SYNTAX score < 23 (109 patients). The SYNTAX score was estimated based on the results of coronary angiography. Logistic regression analyses were performed to evaluate the factors associated with SYNTAX score. Results: Individuals with the SYNTAX score ≥ 23 were more likely to have arterial hypertension, diabetes mellitus, significant stenosis in the left main coronary artery, and higher Lp(a) levels than those with SYNTAX < 23 (all p < 0.05). On univariate analysis, age (OR 1.05, 95% CI 1.02–1.08, p = 0.001), Lp(a) levels (OR 1.04, 95% CI 1.01–1.06, p = 0.001), and arterial hypertension (OR 2.69, 95% CI 1.26–5.74, p = 0.011) were associated with SYNTAX score ≥ 23. Multivariable determinants of SYNTAX score ≥ 23 were as follows: Lp(a) levels (OR 1.03, 95% CI 1.01–1.08, p = 0.029), and age (OR 1.04, 95% CI 1.01–1.07, p = 0.005). The cut-off value for Lp(a) 166.16 nmol/L identifies patients with SYNTAX score ≥ 23 with 97% sensitivity and 44% specificity (area under curve 0.78, p < 0.001). Conclusions: Elevated Lp(a) concentration is associated with a higher SYNTAX score. A cut-off value of Lp(a) above 166.16 nmol/L allows us to identify subjects with SYNTAX score ≥ 23 with good specificity and sensitivity.

Published: November 2024

Background/Objectives: We aimed to evaluate the accuracy of the artificial intelligence (AI)-based software INF-M01 in diagnosing suspected bladder tumors using cystoscopy images. Additionally, we aimed to assess the ability of INF-M01 to distinguish and mark suspected bladder cancer using whole cystoscopy images. Methods: A randomized retrospective clinical trial was conducted using a total of 5670 cystoscopic images provided by three institutions, comprising 1890 images each (486 bladder cancer images and 1404 normal images). The images were randomly distributed into five sets (A–E), each containing 1890 photographs. INF-M01 analyzed the images in set A to evaluate sensitivity, specificity, and accuracy. Sets B to E were analyzed by INF-M01 and four urologists, who marked the suspected bladder tumors. The Dice coefficient was used to compare the ability to differentiate bladder tumors. Results: For set A, the sensitivity, specificity, accuracy, and 95% confidence intervals were 0.973 (0.955–0.984), 0.921 (0.906–0.934), and 0.934 (0.922–0.945), respectively. The mean value of the Dice coefficient of AI was 0.889 (0.873–0.927), while that of clinicians was 0.941 (0.903–0.963), indicating that AI showed a reliable ability to distinguish bladder tumors from normal bladder tissue. AI demonstrated a sensitivity similar to that of urologists (0.971 (0.971–0.983) vs. 0.921 (0.777–0.995)), but a lower specificity (0.920 (0.882–0.962) vs. 0.991 (0.984–0.996)) compared to the urologists. Conclusions: INF-M01 demonstrated satisfactory accuracy in the diagnosis of bladder tumors. Additionally, it displayed an ability to distinguish and mark tumor regions from normal bladder tissue, similar to that of urologists. These results suggest that AI has promising diagnostic capabilities and clinical utility for urologists.

Published: November 2024

Background: Tracheostomy is an essential procedure in cases of respiratory failure in patients requiring long-term ventilation or showing airway obstruction. Tracheostomy has both immediate and long-term complications. Among these, tracheo-innominate fistula is an emergency that is a rare long-term complication. When it occurs, this event is catastrophic for the patient’s life, as it causes death in a very short time due to hemorrhagic shock. Therefore, it is essential to identify risk factors to prevent these cases. Methods: We describe the autopsy findings in a case of death from tracheo-innominate fistula of a patient admitted to the Intensive Care Unit. Results: The autopsy demonstrated, in addition to the large fistula, the coexistence of a malformation of the cervical spine with a significant increase in the diameter of the neck. Therefore, we emphasize in this case the importance of evaluating risk factors in subjects with tracheostomy by highlighting the role of anatomy and the size of the neck as potential predictable risks. Conclusions: The work retraces through a review the pathogenesis of this rare complication and emphasizes the need for early diagnosis and prevention of the risk of death with specific risk scales.

Published: November 2024

Anastomotic leakage (AL) remains a major complication after esophagectomy, especially in patients with esophagogastric cancers who have undergone neoadjuvant therapies, which can impair tissue healing. Endoscopic vacuum-assisted closure (EndoVAC) is an innovative approach aimed at managing AL by facilitating wound drainage, reducing infection, and promoting granulation tissue formation, thus supporting effective healing. This review explores the role and effectiveness of EndoVAC in treating AL post-esophagectomy in esophageal cancer patients. We present an overview of its physiological principles, including wound contraction, enhanced tissue perfusion, and optimized microenvironment, which collectively accelerate wound closure. In addition, we examine clinical outcomes from recent studies, which indicate that EndoVAC is associated with improved leak resolution rates and potentially shorter hospital stays compared to traditional methods. Overall, this review highlights EndoVAC as a promising tool for AL management and underscores the need for continued investigation to refine its protocols and broaden its accessibility. By optimizing EndoVACs use, multidisciplinary teams can improve patient outcomes and advance esophageal cancer care.

Background/Objectives: Many reports on orthodontic miniscrew insertion focus on insertion conditions, such as technique, but not on the insertion environment, such as the operator’s dominant hand. This study aimed to ascertain whether the operator’s dominant hand affects laterality in the success rate of manual and motorized miniscrew insertion methods. Methods: This study retrospectively investigated the medical records of 250 Japanese patients, aged ≥15 years, who underwent miniscrew implantation in the maxilla by right-handed operators with at least 3 years of experience. A cross-tabulation analysis, Chi-square test, and multiple logistic regression analysis were performed to compare the success rates of the two insertion methods. Results: A total of 454 screws were implanted (346 manual and 108 motorized), with an overall success rate of 79.2%. No significant difference was observed in the success rate between the manual (77.7%) and motorized groups (84.2%). Regarding the laterality of the overall success rate, the right-side success rate (84.1%) was significantly higher than that of the left side (75.6%). The right-side success rate in the manual group (82.7%) was significantly higher than that of the left-side (73.0%). In the motorized group, no significant difference was observed between the success rate of insertion on the right (84.6%) and left sides (83.9%). Multiple regression analysis showed that the miniscrew insertion stability was influenced by the insertion side and the operator’s years of experience. Conclusions: The manual screw insertion method was susceptible to environmental factors and less successful in left-side insertion by right-handed operators.

Medical thermography is a non-invasive technique that allows the measurement of the temperature of the human body surface, exploiting the heat emitted by the body through the skin in the form of infrared electromagnetic radiation. Recently, smartphone-based thermography (ST) has drawn considerable attention. This scoping review (SR) aims to describe its current applications and reliability based on currently available research findings, also taking into account the medico-legal implications linked to its use. A search of the sources was conducted on multiple databases (PubMed, Scopus, Cochrane, Lilacs, Google Scholar). Based on a set of eligibility criteria, all articles deemed useful were included in the SR. Collected data, processed with descriptive statistics, are then discussed. From the initial 241 results, after duplicate removal and full-text reading based on inclusion/exclusion criteria, 20 articles were classified according to the main characteristics and indications and outcomes are highlighted based on clinical evidence. The most frequently documented fields of ST are wound care management and vascular surgery. Other disciplines are less explored (dentistry, ophthalmology, otorhinolaryngology, orthopedics, etc.). Practicality, operational simplicity and affordability of mobile thermographic devices are the chief strengths of this technology. Comparative studies with traditional thermal imaging methods are poor in terms of the number of patients analyzed but this technology showed high sensitivity and accuracy in the large number of patients enrolled in observational studies, encouraging the development of further operational protocols in all medical specialties. Gaining a deeper understanding of such techniques will also help settle the medico-legal issues which may arise from the clinical implementation of ST, thus appraising its reliability and safety from that perspective as well.

Background: Perinatal asphyxia is a major cause of neonatal morbidity and mortality, often resulting in hypoxic-ischemic encephalopathy (HIE) with long-term neurodevelopmental impairments. While therapeutic hypothermia has emerged as a promising intervention to reduce brain damage, its specific impact on key brain structures and long-term neurodevelopmental outcomes remains underexplored. This study aims to evaluate the effects of therapeutic hypothermia on brain volumetry, cortical thickness, and neurodevelopment in term neonates with perinatal asphyxia. Methods: This prospective cohort study enrolled 34 term neonates with perinatal asphyxia, with 12 receiving therapeutic hypothermia and 22 serving as controls without hypothermia. Brain MRI data were analyzed using Infant FreeSurfer to quantify the basal ganglia volumes, gray matter, white matter, cerebellum, cortical gyri, and cortical thickness. Neurodevelopmental outcomes were assessed at 18 and 24 months, using the Bayley Scale III, evaluating the motor, cognitive, and language domains. Genetic analyses, including next-generation sequencing (NGS) and microarray testing, were performed to investigate potential neurodevelopmental markers and confounding factors. Results: Neonates treated with hypothermia demonstrated significantly larger gray and white matter volumes, with a 3.7-fold increase in gray matter (p = 0.025) and a 2.2-fold increase in white matter (p = 0.025). Hippocampal volume increased 3.4-fold (p = 0.032) in the hypothermia group. However, no significant volumetric differences were observed in the cerebellum, thalamus, or other subcortical regions. Moderate correlations were found between white matter volume and cognitive outcomes, but these associations were not statistically significant. Conclusions: Therapeutic hypothermia appears to have region-specific neuroprotective effects, particularly in gray and white matter and the hippocampus, which may contribute to improved neurodevelopmental outcomes. However, the impact was not uniform across all brain structures. Further research is needed, to investigate the long-term benefits and to optimize therapeutic strategies by integrating advanced neuroimaging techniques and genetic insights.

Long COVID-19 (LC) is a poorly understood, multifactorial condition that persists for at least three months following SARS-CoV-2 infection. The underlying pathophysiological mechanisms responsible for the wide range of associated symptoms—including fatigue, brain fog, and respiratory issues—remain unclear. However, emerging evidence suggests that the reactivation of latent viral infections, such as Epstein-Barr virus, cytomegalovirus, and varicella-zoster virus, may significantly contribute to the complexity of LC. These latent viruses can be reactivated by SARS-CoV-2, contributing to a chronic inflammatory state that prolongs symptomatology. This review confirms the potential involvement of latent viral infections in LC and examines whether these infections play an independent role or act synergistically with other factors. In addition, recent studies have highlighted viral persistence and immune dysregulation as key elements in LC. Our findings suggest that preventative strategies, including vaccination and antiviral treatments during the acute phase of COVID-19, show potential in reducing LC risk by preventing viral reactivation. However, tailored diagnostic and therapeutic strategies targeting these latent infections are urgently needed. Identifying biomarkers of viral reactivation, particularly for high-risk populations, could be considered another effective strategy to mitigate LC severity. Further research is crucial to better understand the interactions between SARS-CoV-2 and latent infections, and to improve the prevention and treatment of LC.

Published: November 2024

Background: Low but detectable cardiac troponin (cTn) concentrations may reflect cardiovascular (CV) risk in a primary prevention setting. Using previously described thresholds for CV risk stratification, we assessed the influence of sex and cardiometabolic risk factors on the concentrations of high-sensitivity cTn in presumably healthy subjects. Methods: The prospective study included 597 presumably healthy individuals (313 women, 284 men). In all participants, hs-cTnI, hs-cTnT, lipid profile, C-reactive protein, glycated hemoglobin, estimated GFR (eGFR) and B-type naturetic peptide (BNP) were measured. Subjects were categorized into two groups of CV risk, based on hs-cTn non sex-specific cut-off of 5.0 ng/L. For hs-cTnI, sex-specific cut-off values were also used: ≥4.0 ng/L for females and ≥6.0 ng/L for males. Results: Increased CV risk, indicated by hs-cTn concentrations ≥ 5.0 ng/L, was significantly associated with age > 40 years, male sex, obesity and BNP concentrations ≥ 35 ng/L. Using the same 5.0 ng/L threshold, hs-TnT classified approximately twice as many individuals into the CV subgroup compared to hs-cTnI, particularly in males (31% vs. 13%, respectively). After applying sex-specific cut-offs for hs-cTnI, the proportion of females and males with increased risk became similar (8% vs. 9%, respectively). In contrast, using non-sex-specific cut-offs for hs-cTnI resulted in a proportion of 6% for females and 13% for males. BNP and eGFR had significant impact on CV risk stratification using sex-specific cut-offs for hs-cTnI. Conclusions: Our findings suggest the necessity of using sex-specific cut-offs for hs-cTn as a cardiovascular risk marker, in addition to other cardiometabolic factors, in the general population.

Background: Gestational diabetes mellitus (GDM) occurs in approximately 9% of pregnancies, and proper glycemic control is of utmost importance in the prevention of GDM-associated obstetric complications. Flash glucose monitoring (FGM), a subtype of continuous glucose monitoring (CGM), offers intermittent blood glucose scanning and is considered a propitious alternative to the standard method of self-monitoring of blood glucose (SMBG). Aim: The aim of this review was to systematically assess the efficacy and acceptability of FGM in in pregnancies complicated by GDM. Methods: A systematic literature search was performed in the PubMed, MEDLINE, Scopus, and Cochrane databases. The review was conducted following the PRISMA guidelines, and the study protocol has been registered in the PROSPERO database with the registration number CRD42024545874. Results: A total of 872 articles were initially identified, 141 publications underwent an in-depth full-text analysis, resulting in 133 studies being excluded from further assessment. Eventually, eight studies were included in the analysis. Conclusions: The analysis revealed that FGM is a safe and efficient method of glycemic control in GDM. The majority of the studies consider its accuracy comparable to SMBG. Furthermore, FGM is well accepted by patients with numerous advantages in user-friendliness over SMBG.

Morphea, also known as localized scleroderma, is an autoimmune chronic connective tissue disease. It is characterized by excessive collagen deposition in the dermis and/or subcutaneous tissue. The etiopathogenesis of this disease is not fully understood, with endothelial cell damage, immunological disorders, extracellular matrix disorders and factors such as infection, trauma and other autoimmune diseases being considered. As medicine advances, there is increasing evidence that genetic factors play a significant role in disease risk and progression. In addition to environmental factors and genetic predisposition, epigenetic factors may be potential triggers for morphea. Epigenetics studies changes that affect gene expression without altering the DNA sequence, such as microRNAs, long non-coding RNAs or DNA methylation. Understanding the pathogenesis of this disease is key to identifying potential new treatments. There are anecdotal reports of good therapeutic effects following the use of biological drugs such as tocilizumab, a humanized IgG monoclonal antibody; abatacept, a recombinant soluble fusion protein; JAK inhibitors, such as tofacitinib and baricitinib; and a drug used successfully in cancer treatment, imatinib, a tyrosine kinase receptor inhibitor. In this article, we aim to review up-to-date knowledge on the pathogenesis of morphea, with particular emphasis on genetic and epigenetic factors. In addition, we present the new options of morphea treatment based on several case series treated with new drugs that are potential targets for the development of therapies for this disease.
