FTIR monitoring of the 13-valent pneumococcal conjugate vaccine for lung cancer patients: Changes in amides vibrations correlated with biochemical assays

Lung cancer is one of the most lethal cancers. Unfortunately, respiratory tract infections are very common in lung cancer patients, delaying appropriate anticancer therapy. To increase therapy efficiency, in this study we examined the effect of 13-Valent Pneumococcal Conjugate Vaccine on the immune response in lung cancer patients, which indirectly affects the success of anticancer therapy. The study was done using biochemical tests and Fourier Transform InfraRed (FTIR) spectroscopy. For this purpose, serum from lung cancer patients aged 52 ± 9 years (III and IV clinical stage; 79 %; n = 103) before and seven as well as 30 days after vaccination was collected. Obtained results showed increasing concentrations of immunoglobulin IgG and IgG2 groups in patients after vaccination in comparison with group before vaccination. This result was confirmed by FTIR spectroscopy, where higher absorbances of amides vibrations were observed after vaccination. Interestingly, lack of differences in the amides absorbances between patients 7 and 30 days after vaccination were noticed. FTIR spectra also showed changes in the ratio between amide I and amide III as well as between amide II and amide III in the groups of patients after vaccination. From deconvolution of made I range (1600 cm−1–1700 cm−1) decrease of the ratio between α-helix and β-sheet around 0.05 was noticed in serum collected from patients after vaccination in comparison with patients before vaccination. Using Principal Component Analysis (PCA) analysis of FTIR data it was observed that serum collected from all three analyzed groups of samples was possible to differentiate. The highest accuracy in differentiation group of samples before and 7 days after vaccination was visible in amide I, while before and 30 days after vaccination using amide II. Correlation between immunoglobulin IgG and IgG2 concentrations obtained by biochemical assays and FTIR were noticed only in the group of serum collected 30 days after vaccination, which suggested that FTIR spectroscopy reflects biochemical data.

Phenotypic and oncological insights in ANNA1 autoimmunity: Age stratification and biomarker analysis

AbstractObjectiveTo describe the phenotypes, oncological associations, biomarker profiles, and outcomes across different age groups in patients with ANNA1 (anti‐Hu) autoimmunity.MethodsA retrospective review of patients with ANNA1‐IgG in serum/CSF between January 1, 2001, and December 31,2019 was performed. Patients were classified into three groups based on the age of symptom onset. Phage immunoprecipitation sequencing (PhIP‐Seq) and neurofilament light chain (NfL) measurements were done in patient sera/CSF with archived samples.ResultsOf 122 patients, 81 (66%), 20 (16%), and 21 (17%) patients belonged to older adults, young adults, and pediatric groups, respectively. Lung cancer and neuromuscular presentations were more common in older adults (p < 0.001), while limbic encephalitis and neuroblastoma were more common in pediatric patients (p < 0.005). Most young adults (75%) did not have cancer identified. Proportions of patients with a favorable response to immunotherapy were 20%, 30%, and 52% among older adults, young adults, and pediatric groups, respectively. PhIP‐Seq demonstrated significant enrichment for ELAVL4 peptides especially for amino acids 240–289, in the majority of samples evaluated (36/67, 54%). ZIC and SOX2 peptides were significantly enriched in those with central nervous system presentations. Serum NfL levels were elevated in patients with cancer and those with poor long‐term outcomes.InterpretationYoung adults with ANNA1 autoimmunity phenotypically resembled older adults but rarely had an underlying cancer. Pediatric patients frequently presented with limbic encephalitis and neuroblastoma and often responded favorably to immunotherapy. Distinct antigenic signatures may underlie differences in clinical presentations. Serum NfL levels may be a biomarker of poor long‐term outcomes in ANNA1 autoimmunity.

Expression Levels of PF4, ALOX12, ITGA2B, F131A in Pregnant COVID-19 Survivors.

COVID-19 is viral illness caused by SARS-CoV-2. The immediate complications of COVID-19 are well defined and associated with increased mortality. A global effort is required to determine its effects on implantation, fetal growth and labor. Post COVID-19 recovery period presents a further challenge regarding service provision, prevention, and management. To assess the expression of Platelet Factor 4 (PF4), Arachidonate 12-lipoxygenase (ALOX 12), Integrin alpha-IIb (ITGA2B) & Coagulation Factor XIII A Chain F13A1 in post-acute COVID-19 survivors pregnant women. Prospective case control study, conducted on 400 pregnant women. Case group consists of 200 singleton pregnancies who had recovered from COVID-19 since 4-6 weeks before conception. Control group consists of 200 singleton pregnancies with no history for COVID-19. Expression levels of ALOX12, PF4, ITGA2B, and F13A1genes were determined using quantitative reverse transcription polymerase chain reaction method (qRT-PCR). Expression levels of ALOX12, ITGA2B, and F13A1, were significantly higher in the patients group (3.82±9.6, 6.63±8.45, and 8.9±9.1, respectively) (p < 0.05) compared to those in the control group (1.0±6.0, 1.0±8.1, and 0.6±7.6, respectively). No significant difference in PF4 expression between patients and control group (p = 0.3). Results obtained from enrichment analysis have also supported the above findings. Relative expression levels of these candidate genes could be distinguished between post-acute COVID-19 survivors' pregnant women and control group, significant relative gene expression of ALOX12, ITGA2B, and F13A1 may be associated with an increased risk of placenta-mediated adverse pregnancy outcomes.

Comparative characteristics of minimally invasive and classical (median sternotomy) methods of coronary artery bypass grafting

Objective. To analyze the results and comparative characteristics of minimally invasive and classical coronary artery bypass grafting in multivessel coronary artery disease and the presence of critical stenosis. Materials and Methods. Over the past two years, the National Scientific Center of Surgery and Transplantation named after O. O. Shalimov performed mini­invasive coronary artery bypass grafting for multivessel lesions of the coronary arteries in 27 patients (group 1). The comparative study also included 27 patients operated on using the classical method (group 2). The average age of patients was (53.1 ± 3.9) years. There were 46 men (85.2%) and 8 women (14.8%). According to the main indicators, including the number of affected coronary arteries, age, physiological parameters, etc., the groups did not differ statistically significantly. The main methods of the study were coronary angiography, multislice computed tomography of the coronary arteries with 3D reconstruction of the architecture of the great vessels, chest and heart. Results. During the follow­up of patients in both groups for up to a year after the operation, no clinical manifestations of angina and heart failure were noted, which gives reason to state the good function of the shunts. Intra­ and postoperative complications in group 1 occurred in 2 patients: the need for conversion due to cardiac rhythm and hemodynamics (1) and repeated thoracotomy due to bleeding from the arterial shunt (1). In group 2, complications also occurred in 2 patients: sternal diastasis requiring sternoplasty (1) and surgical wound exudation requiring the installation of a vacuum device for 4 days with subsequent secondary suturing (1). Conclusions. Minimally invasive coronary artery bypass grafting is a safe method of myocardial revascularization in multivessel coronary artery disease and critical stenosis. The technique allows for rapid rehabilitation and shorter hospital stays, which is economically beneficial for the hospital. Minimally invasive coronary artery bypass grafting can be considered as an alternative to the classical method of coronary artery bypass grafting with midline sternotomy.

An adaptive decision support system for outpatient appointment scheduling with heterogeneous service times.

Appointment scheduling (AS) plays a crucial role in outpatient clinic management. Traditional methods involve patient grouping using pre-defined rules and scheduling based on these groups. However, pre-defined rules may not adequately capture the heterogeneity in patients' service times (i.e., consultation duration). Advanced machine learning (ML) methods can address individual-level heterogeneity but pose challenges for practical scheduling. To strike a balance, we propose a data-driven AS decision support system, Cluster-Predict-Schedule (CPS), integrating both supervised and unsupervised ML for efficient patient grouping and scheduling. The novelty of CPS lies in its adaptability to service time heterogeneity through a data-driven approach, determining patient groups based on data rather than pre-defined rules. Additionally, CPS includes a generic and efficient algorithm for generating appointment templates adaptable to any number of patient groups. Our system's efficacy is demonstrated using a real-world dataset. Evaluated by the weighted sum of patient wait times, physician idle time, and overtime, CPS achieves up to 15.0% cost reduction compared to the FCFA (first-call, first-appointment) scheme and over 4.7% savings against the common New/Return classification with traditional sequencing candidate (TSC) rules. In addition, CPS enhances outpatient operational efficiency without compromising fairness.

Abstract 4141438: Predictors of Left Atrial Low Voltage Areas Were Different among Age Groups in Patients with Atrial Fibrillation Ablation

Background: Catheter ablation is a well-established treatment for atrial fibrillation (AF). Left atrial low-voltage areas (LVAs) is associated with atrial remodeling following the progression of atrial cardiomyopathy, and poor rhythm outcome after catheter ablation. However, the predictors of LVAs presence have not been fully elucidated in different age groups. Purpose: The purpose of this study was to investigate predictors of the prevalence of LVAs in different age groups. Methods: 1,488 (age, 69 ± 10 years; female, 501 [34%]) consecutive patients who underwent initial ablation were included. Age groups were divided into three groups, namely &lt;60 years old (younger age, n=272), 60-75 years old (intermediate age, n=864), ≥75 years old (older age, n=352). The definition of LVAs was areas with a bipolar voltage of &lt;0.5 mV covering ≥5 cm2 of left atrial surface. Multivariate logistic regression analysis was performed to investigate the clinical predictors of LVAs. Results: Of 1,488 patients, LVAs existed in 352 (24%) patients. In the younger age group, C-reactive protein (odds ratio [OR], 4.5; [95% confidence interval {CI}: 1.5-13], p = 0.006) and previous history of heart failure (OR, 5.6; [95% CI: 1.2-26], p = 0.027) were the independent predictors of LVAs. In the intermediate age group, female (OR, 3.8; [95% CI: 2.6-5.7], p &lt; 0.001), persistent AF (OR, 2.6; [95% CI: 1.7-4.1], p &lt; 0.001), lower body mass index (OR, 0.93; [95% CI: 0.88-0.98], p = 0.004), lower hemoglobin (OR, 0.81; [95% CI: 0.72-0.93], p = 0.002), C-reactive protein (OR, 1.4; [95% CI: 1.0 1-2.0], p = 0.047), diabetes mellitus (OR, 1.8; [95% CI: 1.1-2,8], p = 0.01), left atrial diameter (OR, 1.04; [95% CI: 1.01-1.1], p = 0.007) were the independent predictors of LVAs. In the older age group, female (OR, 2.3; [95% CI: 1.4-3.7], p = 0.01), persistent AF (OR, 3.1; [95% CI: 1.8-5.2], p &lt; 0.001) and lower hemoglobin (OR, 0.83; [95% CI: 0.71-0.97], p = 0.017) were the independent predictors of LVAs. Conclusion: In patients with atrial fibrillation ablation, the independent predictors of LVAs were different among age groups.

Abstract Su1205: The Effect of Targeted Temperature Management on Five-Year Mortality in Comatose Out-of-Hospital Cardiac Arrest Survivors: A Real-World Experience

Background: Hypothermia-Induced Targeted Temperature Management (TTM) is a neuroprotective treatment after the return of spontaneous circulation (ROSC) in comatose survivors of out-of-hospital cardiac arrest (OHCA). However, its effectiveness in all patient subpopulations is debated. While short-term survival has been well studied, the impact of TTM on long-term survival is still unknown. Methods: In a prospective cohort study, 98 comatose survivors of non-traumatic OHCA were recruited from four tertiary-level hospitals in Buffalo, Western New York and followed up for five years. Patients with active cancer, infection, cardiac pathology or surgery in three-month prior to presentation, were excluded. Cardiac arrest characteristics, demographics, comorbidities, and therapeutic interventions were recorded. According to TTM protocols, a target body temperature of 33°C was reached and maintained for 24 hours using either an intravascular cooling catheter or a surface cooling system. This was followed by gradual controlled rewarming over 12-24 hours to normothermia. Factors associated with the receipt of TTM were determined. The effect of TTM on five-year survival was studied using cox-regression analysis. Results: Among comatose patients with mean age of 60.1±14.9 years, 49% received TTM. Females were significantly less likely to receive TTM (35.1% vs 59.3%, p=0.021). In TTM group, the time to ROSC was significantly longer: median [IQR] 14.5 mins (5-19.7) vs 20 mins (12-27), p=0.018. TTM group was more likely to have a history of coronary artery disease (CAD) (12.5% vs 35.4%, p=0.009). Overall, 5-year mortality did not differ significantly between TTM vs. non-TTM: 72.9% vs 66.0%, (HR: 1.134, 95% CI: 0.705-1.826, p=0.603) in univariate and multivariate Cox-regression analysis (Table 1). Conclusion: While females are less likely to receive TTM treatment, TTM is more likely to be used in patients with a longer time to ROSC and a history of CAD. The overall five-year survival remains high in both treatment groups in all eligible patients, as well as in shockable and non-shockable rhythm groups studied separately. Larger cohort studies are needed to determine the patients who may benefit most from TTM.

Possibly more favorable short‐term outcomes with minimally invasive surgery than with open surgery in total gastrectomy for locally advanced gastric cancer: A single high‐volume center study

AbstractBackgroundMinimally invasive total gastrectomy (MTG) requires advanced surgical skills and is still associated with a higher rate of postoperative complications than other types of gastrectomy. Additionally, the short‐term outcomes of MTG compared to open total gastrectomy (OTG) for locally advanced gastric cancer have yet to be demonstrated.MethodsWe retrospectively compared short‐term outcomes between MTG and OTG for locally advanced gastric and esophago‐gastric junctional cancer, performed at the Cancer Institute Hospital, Tokyo, during the period from January 2017 to March 2024. Propensity score matching (PSM) was conducted to adjust for potential confounders.ResultsIn total, 359 patients were included, with 190 remaining after PSM, resulting in 95 in each group. The MTG group experienced a significantly lower incidence of postoperative complications of Clavien–Dindo classification (C‐D) ≥3 than the OTG group (3.2% vs. 11.6%, p = 0.026). Moreover, the rate of postoperative intra‐abdominal infectious complications (IAIC) was significantly lower in the MTG than in the OTG group (C‐D ≥ 2; 7.4% vs. 17.9%, p = 0.029 and C‐D ≥ 3; 2.1% vs. 9.5%, p = 0.030, respectively). Subgroup analyses showed the odds ratios for IAIC with C‐D ≥ 2 to be more favorable for the MTG than the OTG group in male patients, those ≥70 years of age, patients without esophageal invasion, those without neoadjuvant chemotherapy, those diagnosed with cT≥3, and patients not undergoing combined resection of other organs except for the gallbladder or spleen.ConclusionsMTG for locally advanced gastric cancer may provide improved short‐term outcomes compared to OTG, when performed or supervised by surgeons with high proficiency in laparoscopic techniques.

Evaluation of pseudoexfoliation syndrome patients with systemic immune indexes.

The aim of this study was to investigate the level of peripheral blood systemic immune indexes in pseudoexfoliation syndrome (PXS) patients and to compare the results with healthy controls. This study included 143 healthy controls (group 1) and 100 patients (group 2). Peripheral blood samples were collected from all participants. Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), monocyte to lymphocyte ratio (MLR), systemic immune inflammation index (SIII), systemic inflammation response index (SIRI), systemic inflammation modulation index (SIMI) and aggregate systemic inflammation index (AISI) were calculated. According to complete blood count, leukocyte, monocyte and platelet counts showed a statistically significant difference between the two groups (p < 0.001 for all). Systemic immune indexes (NLR, PLR, SIII, SIRI, SIMI and AISI) in group 2 were statistically significantly higher compared to group 1 (PLR for p = 0.011, others p < 0.001). In conclusion, systemic immune indexes (NLR, MLR, PLR, SIII, SIRI, AISI and SIMI) were elevated in PXS patients compared to healthy controls. These indexes may serve as an easy, simple and cost-effective tool to assess the degree of systemic inflammation in patients, playing an important role in recognizing the underlying mechanisms of diseases and thus potentially guiding treatment.

Serum level of myostatin and type I interferon-inducible gene expression in dermatomyositis patients and its relation to insulin resistance

Abstract Background Data regarding the relation between serum myostatin level, type I interferon-inducible gene expression and insulin resistance in dermatomyositis patients are limited. This study aimed to assess serum myostatin level, homeostatic model assessment of insulin resistance (HOMA-IR) and type I interferon-inducible gene expression in dermatomyositis patients. We evaluated the role of serum myostatin level, and type I interferon-inducible gene expression in the pathogenesis of dermatomyositis as well as the relation of serum myostatin level and type I interferon-inducible gene expression to the occurrence of insulin resistance. We evaluated serum levels of myostatin and HOMA-IR utilizing ELISA as well as IFIT1 and Mx1(MxA) gene expression with RT-PCR in 25 dermatomyositis patients (group A) and 25 obviously sound subjects as controls (group B). Results Among group A, body mass index, serum levels of myostatin, fasting insulin, HOMA-IR, IFN-inducible genes Mx1 and IFIT1 were more significantly increased as well as; serum level of myostatin was positively correlated with age, gender, fasting insulin level, body mass index, and HOMA-IR. Conclusions Serum level of myostatin, Mx1 and IFIT1 gene expression act as hazard factors of insulin resistance in group A.

RADT-09. CHEMORADIOTHERAPY WITH TEMOZOLOMIDE VS. RADIOTHERAPY ALONE IN PATIENTS WITH IDH WILD-TYPE AND TERT PROMOTER MUTATION HISTOLOGICAL GRADE 2/3 GLIOMAS: A POSTHOC ANALYSIS OF A RANDOMIZED CONTROLLED TRIAL

Abstract PURPOSE In 2016, we initiated a signal center prospective randomized trial to compare chemoradiotherapy (CRT) with temozolomide (TMZ) to radiotherapy (RT) alone in patients with IDH wild-type and TERT promoter mutation histological grade 2/3 gliomas. This study demonstrated patients who received CRT had a longer median OS than those who received RT alone and found no statistical difference in PFS between the two groups. Now, we recruited more patients in the CRT group to further explore whether there were differences in PFS between patients treated with CRT and RT. Besides, we explored the effect of MGMT promoter (MGMTp) methylation status on OS and PFS in patients receiving CRT therapy in the STUPP schedule. METHODS We expanded the scope by enrolling 21 participants in the CRT group and extending the follow-up period. OS and PFS were analyzed using the log-rank test, and high-risk factors were explored through Cox regression analysis. RESULTS Patients’ median follow-up is 21.9 months. CRT group has a longer median OS (25.3 vs 17.2 months; P = 0.029, HR = 0.443) and PFS (14.6 vs 8.3 months; P = 0.0008, HR = 0.387) than the RT group. Multivariate analysis identified CRT as a favorable prognostic variable for both OS (P = 0.003) and PFS (P = 0.002). The status of MGMTp methylation did not affect OS (P = 0.560, HR = 1.30) and PFS (P = 0.75, HR = 0.88) in patients with IDH-wt/TERTp-mut receiving TMZ chemotherapy. CRT with TMZ did not significantly increase grade 3 or higher toxicities. CONCLUSIONS The long-term results confirmed that the OS and PFS benefits of the RT plus TMZ regimen exceeded those of the RT alone group in patients with IDH-wt/TERTp-mut gliomas.

AGE-RELATED CHARACTERISTICS OF ISCHEMIC HEART DISEASE INCIDENCE IN UKRAINE: A TWO-CENTER STUDY

Purpose of this study is to investigate the age-related characteristics of the incidence of coronary heart disease in Ukraine, considering sex differences. Materials and Methods: The study included patients with coronary heart disease who underwent coronary artery bypass surgery on a beating heart (n = 3,674), comprising 3,061 males and 613 females. The average age of the participants was 60.6 ± 0.8 years. The analysis was based on data obtained from primary medical documentation, including medical histories, anamnestic information, and extracts from patients’ outpatient cards. The research design categorized participants by age group according to the World Health Organization age classification and by sex. Results: The article presents the incidence rates of coronary artery disease based on patient age groups, classified according to the World Health Organization, and sex. The distribution of patients by age groups was analyzed while considering sex, and the frequencies and average ages of the patients were determined. It was found that the incidence of coronary artery disease was highest among the most prevalent age groups in Ukraine's population: middle-aged and elderly patients. The frequency of early postoperative mortality was 0.6%, and it correlated with age-related incidence rates of coronary heart disease. Notably, early postoperative mortality was significantly higher in age groups with the highest incidence of coronary heart disease, specifically among middle-aged and elderly patients (p = 0.03, χ² = 4.69). Conclusions: In this retrospective two-center study of patients with coronary heart disease, it was determined that male patients were affected five times more frequently than female patients. The most common age groups for patients with coronary heart disease were identified as middle-aged and elderly. Early postoperative mortality following coronary artery bypass surgery on a beating heart was found to be 0.6%, with the highest rates observed in elderly (54.6%) and middle-aged (31.8%) patients. The frequency ratios demonstrated statistical significance favoring elderly patients (p = 0.03, χ² = 4.69). The frequency of early postoperative mortality was significantly higher among male patients (p = 0.0001, χ² = 40.33).

Clinical features and prognostic factors of IV combined small cell lung cancer: A propensity score matching analysis.

Nowadays, the characteristics and treatment of combined small-cell lung carcinoma (CSCLC) remain controversial. This study aimed to analyze the features of clinical demographics, survival outcomes and treatment modalities among IV CSCLC, IV SCLC and IV NSCLC, to provide more evidence for the study of IV CSCLC. All CSCLC, SCLC and NSCLC patient data were obtained from the SEER database (2010-2020). Pearson's χ2 test was used to compare the differences in clinical characteristics. Propensity score matching (PSM) was utilized to balance the bias of the variables between patients. Univariate and multivariate Cox proportional hazards regression analyses were performed to identify prognostic factors. KM analysis was used to calculate survival. Adjusted analyses for the primary outcome of different treatment modalities of IV CSCLC, IV SCLC and IV NSCLC were performed using Cox regression models. A total of 493 patients with IV CSCLC, 35503 patients with SCLC, 122807 patients with IV NSCLC were included in this study. The demographic characteristics and tumor characteristics of the three groups were different. Before PSM, there were significant differences in OS and CSS among IV CSCLC, IV SCLC and IV NSCLC, After PSM, there was a significant difference in OS and CSS between the IV CSCLC and IV NSCLC. Risk/protective factors for OS and CSS were different in three groups. Chemotherapy, radiotherapy, and surgery can improve IV CSCLC's survival time. The combination of surgery and chemoradiotherapy treatment group for patients with IV CSCLC demonstrated best OS compared to control treatment groups, and the surgery combined chemotherapy treatment group exhibited the best CSS. Additionally, for select patients with stage IV CSCLC who have missed the window for surgical intervention at the time of initial diagnosis, chemoradiotherapy presents a viable and effective treatment option. The clinical characteristics IV CSCLC, IV SCLC and IV NSCLC were significantly different. The prognosis for IV CSCLC is notably poorer than IV NSCLC, similar to IV SCLC. Surgery combined therapy emerged as the preferred treatment modalities and chemoradiotherapy was a good choice for patients who have lost the indication of surgery for patients diagnosed with IV CSCLC.

The Impact of the Position of the Humeral Head Relative to the Glenoid on Iatrogenic Fractures During Shoulder Dislocation Reduction

Background and Objectives: The aim of this study was to investigate the relationship between the position of the humeral head relative to the glenoid and the occurrence of iatrogenic surgical neck fractures of the humerus during anterior glenohumeral dislocation reductions. Materials and Methods: Patients with first-time anterior shoulder dislocations without generalized joint hyperlaxity were included. The humeral head displacement ratio was calculated as the distance between the medial border of the humeral head and the anterior glenoid rim divided by the diameter of the humeral head. Demographic data, concomitant tuberculum majus fractures, and the deltoid tuberosity index were recorded. Patients were divided into three groups: Group 1 (iatrogenic fracture development during closed reduction (CR)), Group 2 (failed CR), and Group 3 (successful reduction without iatrogenic fracture). Complicated dislocations were included in Groups 1 and 2, while uncomplicated dislocations were those in Group 3. Results: The study included 89 patients with a mean age of 46.44 ± 19.02 years (64 males, 25 females). Concomitant tuberculum majus fractures occurred in 37 (41.6%) cases. Iatrogenic surgical neck fractures occurred in 10 patients (Group 1), and CR was unsuccessful in 8 patients (Group 2), totaling 18 cases of complicated dislocations. Reduction without iatrogenic fracture was achieved in 71 cases (Group 3). The mean humeral head displacement ratio was higher in the complex dislocation group (92.91 ± 15.34 vs. 75.01 ± 13.80; p &lt; 0.001). Complicated dislocations were more frequent in patients with tuberculum majus fractures (p = 0.031). Subgroup analysis showed higher humeral head displacement ratios in Groups 1 and 2 compared to Group 3 (p = 0.010 and p = 0.06, respectively). Tuberculum majus fractures were more frequent in Group 1 compared to Group 3 (p = 0.013), with no significant difference between Groups 2 and 3. Conclusions: In patients experiencing first-time traumatic anterior shoulder dislocations, a greater medial displacement of the humeral head relative to the glenoid rim significantly increases the risk of iatrogenic humeral fractures and the likelihood of unsuccessful closed reduction attempts.

Efficacy of One Anastomosis Gastric Bypass Versus Sleeve Gastrectomy and Roux-en-Y Gastric Bypass for the Treatment of Type 2 Diabetes Mellitus: a Systematic Review and Meta-Analysis of Randomized Clinical Trials.

The worldwide prevalence of type 2 diabetes mellitus (T2DM) is increasing in parallel with obesity. One anastomosis gastric bypass (OAGB) is considered effective to treat both T2DM and obesity. The aim of this study was to evaluate the efficacy of OAGB versus sleeve gastrectomy (SG) and Roux-en-Y gastric bypass (RYGB) for treatment of T2DM, analyzing data exclusively from randomized control trials (RCTs). Α systematic review of published RCTs comparing OAGB versus RYGB or SG (control groups) in T2DM patients regarding diabetes remission and weight loss was performed. Primary endpoints were T2DM remission rate and 1-year and 5-year % weight loss postoperatively. Initial search identified 39 references, of which 8 RCTs were considered eligible for meta-analysis inclusion, comprising 636 patients (311 OAGB, 122 RYGB, 203 SG patients). Main meta-analysis findings were: i) higher 1-year %EWL for OAGB than control group (p = 0.04); ii) higher 5-year %EWL for OAGB than control group (p < 0.01); iii) no difference in 1-year remission rate of T2DM between OAGB and control group (p = 0.14); iv) 28% higher 5-year remission rate of T2DM for OAGB than control group (p < 0.01). OAGB had statistically significant better outcomes compared to RYGB and SG regarding T2DM remission and %EWL at 5years. Further pathophysiologic studies are needed to indicate the most potent bariatric procedure in patients with T2DM and obesity.

Efficacy and safety of tirofiban plus recombinant tissue plasminogen activator versus recombinant tissue plasminogen activator alone in acute ischemic stroke patients: a meta-analysis

ObjectiveTirofiban plus recombinant tissue plasminogen activator (rtPA) shows good efficacy and safety in treating acute ischemic stroke (AIS) patients, but there is a lack of comprehensive assessment. This meta-analysis aimed to compare the efficacy and safety of rtPA plus tirofiban with rtPA alone in AIS patients. MethodsThis meta-analysis retrieved studies comparing rtPA intravenous thrombolysis followed by tirofiban (rtPA+T group) versus rtPA intravenous thrombolysis alone (rtPA group) for AIS patients in Excerpt Medica Database, Web of Science, Cochrane, PubMed, China National Knowledge Infrastructure, Wanfang, and SinoMed until March 2024. ResultsTwenty studies with 2048 AIS patients were enrolled in this meta-analysis. National Institute of Health stroke scale (NIHSS) score after treatment was lower in the rtPA+T group than the rtPA group [standardized mean differences (SMD)=-1.41; 95 % confidence interval (CI)=-1.83, -0.98; P<0.001]. The proportion of AIS patients achieving a favorable functional outcome (modified Rankin Scale score ≤2) was increased in the rtPA+T group versus the rtPA group [relative risk (RR)=1.13; 95 % CI=1.05, 1.21; P=0.001]. The incidence of re-occlusion was lower in the rtPA+T group than in the rtPA group (RR=0.24; 95 % CI=0.10, 0.59; P=0.002), but the incidence of intracranial hemorrhage (ICH) (RR=0.85; 95 % CI=0.51, 1.43), symptomatic ICH (RR=1.10; 95 % CI=0.43, 2.84), and mortality (RR=1.39; 95 % CI=0.53, 3.65) was not different between the two groups (all P>0.05). The stability assessed by sensitivity analysis was good, and no publication bias was found. ConclusionrtPA plus tirofiban achieves superior efficacy with comparable safety profiles compared to rtPA alone in AIS patients.

The Significance of Albumin Concentration and some of its Altered Forms in Iraqi Patients with Chronic Hepatitis B Virus

Background: The liver synthesizes albumin, a pivotal protein with approximately 60-65% of total plasma proteins. During ischemic attacks linked to oxidative stress, reactive oxygen species, and acidosis, the properties of albumin undergo alterations. This leads to generation of ischemia-modified albumin, which is characterized by a diminished metal-binding capacity, particularly for transition metals like copper, nickel, and cobalt. Objectives: This study aimed to assess the significance of serum albumin and ischemia-modified albumin concentrations in Iraqi individuals with hepatitis B virus Methods: A case control study consisted of 50 patients with hepatitis B were recruited from Gastroenterology hospital in the Medical city/ Baghdad/ Iraq, during the period January to February in 2023, The patients group included males and females; whose ages ranged from 18 years to 77 years with a mean value 44 year. Meanwhile the study group consisted of 50 age- and sex-matched normal healthy individuals. Albumin concentration was determined in the serum samples, using a Biosystems kit, and ischemia modified albumin concentration were measured through the albumin cobalt binding test. The ischemia modified albumin/ [albumin] ratio and Ischemia modified albumin index were then calculated. Statistical Analysis: results were reported as a mean value ± standard deviation. The differences were considered highly significant if (p &lt; (0.001), and significant where (p = (0.002) and (p = (0.033) Results: lower serum albumin concentration was measured in the patients group, while the mean value of ischemia modified albumin concentration in the patients' group and healthy control were 0.466 ± 0.114 absorbance unit &amp; 0.395 ± 0.070 absorbance unit, respectively, with a statistically significant increase (P &lt; 0.001). The ischemia modified albumin ratio in the hepatitis B patients and control groups were 0.172 ± 0.073 and 0.117 ± 0.050, respectively, showing a significant increase as well (P &lt; 0.001). Additionally, the ischemia modified albumin index in the patients and the control groups were 0.491 ± 0.167 &amp; 0.390 ± 0.131, respectively, with a statically significant increase (p&lt;0.001) in the patients group. Conclusion: In the patients’ group with hepatitis B, serum albumin concentration is decreased, while the level of ischemia modified albumin, ischemia modified albumin ratio, and ischemia modified albumin index are increased. The elevation in ischemia modified albumin, ischemia modified albumin ratio, and ischemia modified albumin index were more prominent in younger patients and those with albumin concentration less than 4g/dl. Moreover, the prevalence of hepatitis B is higher in men compared to women.

Effectiveness of pulse methylprednisolone in patients with non-human immunodeficiency virus pneumocystis pneumonia: a multicentre, retrospective registry-based cohort study

BackgroundA recent database study and meta-analysis reported that adjunctive glucocorticoid therapy reduces mortality in patients with non-human immunodeficiency virus-associated (non-HIV) Pneumocystis jirovecii pneumonia (PCP), having hypoxemia. However, the optimal glucocorticoid dose remains unclear. Our study aimed to evaluate the effectiveness of pulse methylprednisolone compared with mild-to-moderate steroid doses in patients with non-HIV PCP.MethodsThis multicentre retrospective cohort study included adults with non-HIV PCP receiving adjunctive steroids at three Japanese tertiary care hospitals from June 2006 to March 2021. Patients were categorised into pulse methylprednisolone and mild-to-moderate dose groups. Pulse methylprednisolone involved an initial intravenous infusion of 500–1000 mg methylprednisolone daily, while the mild-to-moderate dose was lower. Primary and secondary outcomes were 30-day and 180-day mortality from treatment initiation. Patient characteristics were adjusted using propensity score analysis with overlap weighting. Subgroup analysis focused on patients with respiratory failure.ResultsThe study included 139 patients with non-HIV PCP: 55 in the pulse methylprednisolone group and 84 in the mild-to-moderate dose group. After adjusting for patient background, 30-day mortality (14.2% vs. 15.5%, P = 0.850) and 180-day mortality (33.5% vs. 27.3%, P = 0.516) did not differ significantly between groups. Subgroup analysis revealed no significant associations among patients with respiratory failure.ConclusionsAfter adjusting for patient characteristics, no difference in prognosis was observed between pulse methylprednisolone and mild-to-moderate dose groups in patients with non-HIV PCP. A mild-to-moderate dose of adjunctive corticosteroid may suffice for treating non-HIV PCP.

Prognostic impact of age on outcomes of hepatic decompensation in patients with compensated cirrhosis (CHESS2102): an international, multicenter cohort study.

Baveno VII criteria (B7C) and Baveno VI criteria (B6C) have been widely used to estimate the risk of hepatic decompensation. However, the impact of age on these criteria warrants further investigation. The international, multicenter cohort study included 1138 patients with compensated cirrhosis (median follow-up of 40.6 months), aiming to evaluate the value of age in predicting hepatic decompensation. We identified age as an independent predictor of hepatic decompensation, with 60 years determined as the optimal cut-off value. The occurrence of decompensation was 18.7% and 6.7% in the older (age ≥60 years) and younger (age <60 years) groups, respectively (p<0.001). We subsequently integrated age into the existing Baveno criteria. In patients not meeting Baveno criteria (defined as not meeting B6C or B7C), the older group exhibited a significantly elevated risk of decompensation compared to the younger group (p<0.05). However, no significant difference was observed between the older and younger groups in patients meeting Baveno criteria (p>0.05). In conclusion, our study demonstrated that integrating age into the Baveno criteria could enhance the assessment of hepatic decompensation. Age should be considered before discharging patients with compensated cirrhosis from the surveillance of hepatic decompensation.
