ROLE OF FUNGI IN COVID-19 PATIENTS WITH CHRONIC LUNG DISEASE IN RANI DURGAVATI MEDICAL COLLEGE, BANDA (FORMERLY GOVERNMENT ALLOPATHIC MEDICAL COLLEGE, BANDA 210001 (UP) INDIA.)

Background: Fungal infections of the lung have gained increasing recognition in the field of infectious disease and they are difficult to diagnosis. Advances in modern treatment like antibiotics corticosteroids, Immunosupressants and anticancer drugs have lead to increase in opportunistic fungal infections including bronchopulmonary Candidiasis and Bronchopulmonary aspergillosis has also increased, commonly occurs in COVID-19 patients of pre existing bronchial asthma. In India there is high prevalence of chronic lung diseases including bronchial Asthma, yet the diagnosis of aspergillosis and Candidiasis. An association between asthma and aspergillosis was noted and confirmed by isolation of Aspergillus species more commonly in sputum of Asthma patients (Lum et al., 2020 Singla, N. et al., 2019). Subject and Methods: To find out the role of fungi in 50 Corona virus (RTPCR test) positive patients of chronic lung disease (non tubercular) like COPD, Chronic Bronchitis with or without emphysema, Broncheichtasis, Bronchial Asthma were included. Patients were attended and admitted in Rani Durgavati Medical College (RDMC) and Hospital, Banda (UP) India, in a one year period was taken up from December 2020 till December 2021. The diagnosis of these cases v/as established by clinical features, radiological examination of chest, ECG, pulmonary function tests. Laboratory procedure for isolation and identification of fungi in bronchoalveoiar lavage. Each specimen of Bronchoalveloar Lavage (BAL) was subjected to various laboratory procedures for isolation and identification of fungi. Result: Different fungal species were cultured in 26% total cases. 20% isolates were positive for fungi alone whereas rest 6% cases showed both bacterial and fungal pathogens amongst fungi Candida was the predominant isolate in 16% cases followed by Aspergillus in 8% cases and Histopfasms capsulatum in just1(2%) case. Fungal isolates in bronchial aspirates were sensitive to Amphotericin B, Fluconazole, etc. Conclusion: COVID-19 Patients which are already containing chronic lung diseases especially COPD, bronchiectasis is more common in elderly males. The Bronchiectatic patients are also at risk of getting, fungal infections Patients of chronic lung disease who are on long-term antibiotic therapy, and or steroids are more predisposed to get these opportunistic infections. Another conclusion from it is clear that there is great need better and judicious use of antibiotics in patients to prevent drug resistance, to prevent further progression of the diseases.

Radiological Assessment of Pulmonary Vascular Changes and Gastrointestinal Changes in COVID-19 Patients Referred to a Tertiary Health Care Centre in Chennai, India: A Prospective Cross-Sectional Study

Background: The COVID-19 pandemic, caused by the SARS-CoV-2 virus, has led to significant morbidity and mortality worldwide since its emergence in 2019. While primarily a respiratory illness, COVID-19 can also affect other organ systems, including the vascular and gastrointestinal systems. COVID-19 infection is linked to both venous and arterial thrombosis, with numerous studies indicating a heightened risk of pulmonary embolism (PE) among patients. Autopsies have revealed pulmonary vasculature thrombosis and bowel ischemia in COVID-19 cases. Aim: This prospective cross-sectional study aimed to assess radiological pulmonary vascular changes, specifically pulmonary embolism (PE), and gastrointestinal changes in COVID-19 patients referred to a tertiary healthcare center in Chennai, India. Methods: CT pulmonary angiography (CTPA) and contrast-enhanced CT of the abdomen were conducted in 100 COVID-19 positive patients meeting the inclusion and exclusion criteria. Evaluation of pulmonary vascular changes and bowel changes was performed by a radiologist with five years of experience. Subsequently, statistical analysis was carried out to determine the significance of the relationship between COVID-19 patients and the occurrence of pulmonary vascular and bowel changes. Results: In our study, 11 patients exhibited pulmonary thromboembolism, and 7 patients showed significant bowel changes. There is a positive correlation between the prevalence of PE in COVID-19 patients. PE was diagnosed at a mean of 11 days from the onset of the disease. Out of 24 patients with severe acute respiratory illness (SARI), 7 showed PE in CTPA. Additionally, out of 10 mechanically ventilated patients, 7 had PE in CTPA. Among the 7 patients with bowel changes, 4 had PE in CTPA, indicating a significant association with PE. The observed bowel changes were attributed to intravascular thrombosis. Conclusion: Based on our findings, individuals with COVID-19 often develop pulmonary emboli and bowel changes. Multivariate analyses revealed a connection between invasive mechanical ventilation and PE. Our results suggest that patients with severe clinical manifestations of COVID-19 may also have concurrent acute PE. Thus, for these patients, utilizing contrast-enhanced CT scans instead of standard non-contrast CT scans may aid in treatment decision-making.

Efficacy of Methylprednisolone in Acute Respiratory Distress Syndrome- COVID-19 Middle Euphrates Patients

Background: The coronavirus disease 2019 was initially identified in Wuhan, the Chinese province of Hubei, in December 2019, and it quickly spread to other parts of the world. Objective: To assess the efficacy of MP in ARDS COVID-19 patients who admitted to ICU. Patients and Methods: Prospective cohort study, the data collection was among COVID 19 positive patients with severe acute respiratory syndrome attending the Intensive care unit One-hundred patients were included in this study: MP treated group included forty patients who exposed to high doses of MP 1 gm first day then 500 mg for other 4 days with standard treatment for COVID 19.Non MP treated group included sixty patients with standard care for COVID 19 alone. Results: A total of 100 patients with ARDS-COVID 19 positive were included in this study (40 MP treated and 60 non MP treated control group). The outcome for both group after 5 days has shown that; in exposed group: (27) 67.5 % of patients were improved, (7) 17.5 %of patients were worsen and (6) 15 %of patients died. In non MP treated group: 21.7 %of patients were improved, ( 40) 66.7 %of patients were worsen and(7) 11.7 %of patients were died and there were a significant association in the outcome and MP expose. Conclusion: In patients with ARDS COVID 19 positive, early administration of pulse dose of methylprednisolone was associated with remarkable improvement of general condition, vital signs and SPO2 ,and inflammatory markers .

The Impact of IgG Fc-Glycosylation on Disease Dynamics in Primary Sjögren's Disease- Insights from the Belgian Sjögren's Syndrome Transition Trial.

Glycans attached to the fragment crystallizable region (Fc) of IgG antibodies influence their pro- or anti-inflammatory effector function. We aimed to explore the interrelation between the Fc-glycosylation profile and disease transition, disease activity and outcome in patients with suspected and confirmed primary Sjögren's Disease (SjD). IgG Fc-sialylation and IgG Fc-galactosylation serum levels were determined in 300 patients from the Belgian Sjögren's Syndrome Transition Trial (BeSSTT). This cohort includes both suspected and confirmed SjD patients meeting the 2016 ACR/EULAR criteria. Salivary gland involvement was evaluated through ultrasonography (Hocevar score 0-48) and histopathology (focus score). The relative amount of sialylated and galactosylated IgG was determined by capillary electrophoresis after using the endoS endoglycosidase based assay. SjD patients exhibited significantly lower sialylation and galactosylation levels versus asymptomatic anti-SSA carriers and sicca patients. Lower sialylation and galactosylation levels were significantly associated with an increase in B-cell activation markers and distinct autoantibody profiles, particularly with multiple autoantibody reactivities. They were also linked to histopathological salivary gland alterations, higher Hocevar scores and importantly with risk factors for non Hodgkin lymphoma (NHL) development. In contrast, mono-anti-Ro60 positive and anti-SSA negative SjD patients had normal IgG Fc-glycosylation. This study points to a novel role of IgG Fc-glycosylation in SjD in predicting disease transition, monitoring disease activity, and risk stratification for NHL development.

Trauma Presentations To The ED, Are We Improving With Frailty Initiatives?

Abstract Background An emergency department serving as a regional Trauma Centre for the Midlands, now has a Rapid Access Frailty Team (RAFT) which provides timely assessments of all Frail patients over 75. The department has an approximate trauma attendance of 111 (2023 figures) annually within this age cohort. In line with our NOCA guidelines we performed a retrospective review of our trauma presentations since the introduction of the RAFT initiative, looking at the patient’s presentations and how interventions can improve our Trauma management. Methods This was a retrospective review of FRAIL positive patients in from January/February 2023 and January/February 2024 based on NOCA 2021 subsets of trauma data. Data was collected using examination of IPIMS and ED notes obtained for review. We compared both years to see we could see if RAFTT interventions improved our trauma triage and care. Results The predominant mechanism of injury remains to be a fall (85% in 2023 and 74% in 2024), and the majority of traumas being in the home setting (70% in 2023 and 78% in 2024). By the early involvement of a nurse specialist, physio/OT and doctor, time to be seen has reduced by 23% since the introduction of the team, time to imaging has improved by 51% and time to bed if admitted has improved by 19%. Pre alerts remain low, similar to national data findings (10% in 2023, but up to 15% in 2024). Conclusion Data points to the team’s provision of timely, patient-focused assessments and interventions for the older person are improving outcomes. The unique assessment skills that the team deliver aids rapid assessment, supports timely decision-making and referral as appropriate; improving the patient’s journey by either facilitating early discharge or providing early goal-setting therapy interventions at the start of the hospital journey.

Frequency of Group A Streptococcus Infection and Analysis of Antibiotic Use in Patients with Pharyngitis-A Retrospective, Multicenter Study.

Streptococcus pyogenes is responsible for 20-30% of pharyngitis in children and 5-15% in adults. The ineffective treatment of group A Streptococcus (GAS) infections can result in postinfectious sequelae. This study aims to evaluate the frequency of GAS pharyngitis and assess the management of patients with pharyngitis and antibiotic use. We conducted a multicenter, retrospective analysis of medical records from nine primary care centers in Poland. The study enrolled 1949 medical records of patients (children 67.4%, adults 32.6%). An infection of Streptococcus pyogenes, based on a rapid strep test, was diagnosed in 830 patients (42.6%). In the comprehensive study group of 1949 patients, 1054 (54.1%) were given antibiotics. Notably, 224 patients had a negative rapid strep test result but still received antibiotic treatment, underscoring the complexity of treatment decisions. The most commonly used antibiotics were oral penicillin V in 431 cases (41%) and amoxicillin in 219 cases (20.8%). We observed no significant difference between positive rapid strep test results and patients' sociodemographic data and comorbidities. The prevalence of GAS was 42.6% in the analyzed records of patients with pharyngitis, and 54.1% were prescribed antibiotics. Antibiotics were overprescribed for sore throats. Strategies are needed to promote rational antibiotic use.

Cognitive impairments in autoimmune encephalitis: the role of autoimmune antibodies and oligoclonal bands.

The presence of oligoclonal bands (OCBs) in cerebrospinal fluid (CSF) is a pivotal diagnostic marker for multiple sclerosis (MS). These bands play a crucial role in the diagnosis and understanding of a wide array of immune diseases. In this study, we explore the relationship between the cognitive profile of autoimmune encephalitis (AIE) and the presence of OCBs in CSF, with a particular emphasis on NMDA receptor antibodies. We studied a cohort of 21 patients across five tertiary centers, segregated into two distinct categories. One group comprised individuals who tested positive only for autoimmune encephalitis antibodies indicative of encephalitis, while the other group included patients whose CSF was positive for both autoimmune encephalitis antibodies and OCBs. Our investigation focused primarily on cognitive functions and behavioral alterations, supplemented by auxiliary diagnostic assessments such as CSF cell count, magnetic resonance imaging (MRI), and electroencephalogram (EEG) results, evaluated for the two patient groups. To validate our findings, we employed statistical analyses such as Fisher's exact test with Benjamini-Hochberg correction. Our study included 21 patients, comprising 14 who were presented with only autoimmune encephalitis antibodies, and 7 who were dual-positive. Among these patients, we focused on those with NMDA receptor antibodies. Of these, five were dual positive, and nine were positive only for NMDA receptor antibodies. The dual-positive NMDA group, with an average age of 27 ± 16.47 years, exhibited significantly higher CSF cell counts (p=0.0487) and more pronounced language and attention deficits (p= 0.0264). MRI and EEG results did not differ significantly between the groups. Our results point to OCBs as an additional marker of disease severity in AIE, especially in NMDA receptor-antibody positive patients, possibly indicating a broader inflammatory process, as reflected in elevated CSF lymphocytes. Regular testing for OCBs in cases of suspected AIE may aid in disease prognosis and identification of patients more prone to language and attention disorders, improving diagnosis and targeting treatment for these cognitive aspects.

Serum vitamin D levels and the severity and clinical course of COVID-19.

Low vitamin D levels are associated with different pulmonary diseases, such as chronic obstructive pulmonary disease, bronchial asthma, and obstructive sleep apnea. In this study, we aimed to assess the relation between vitamin D levels and COVID-19 severity. Positive COVID-19 patients were subjected to clinical examination, computed tomography of the chest, and laboratory investigations. Serum vitamin D level was measured and correlated with the severity and the clinical course of the disease. The study included 72 patients, classified into four groups according to the severity of the disease. There was a statistically significant difference between the four groups regarding age, lymphocyte count, serum vitamin D, C-reactive protein, and lactate dehydrogenase levels. Serum vitamin D levels can be correlated with COVID-19 severity and clinical course.

Insights into the molecular network characteristics of major HIV-1 subtypes in developed Eastern China: a study based on comprehensive molecular surveillance data.

This study aimed to conduct a comprehensive molecular epidemiology study of major HIV-1 subtypes in developed Eastern China (Zhejiang Province). Plasma samples and epidemiological information were collected from 4180 newly diagnosed HIV-1 positive patients in Zhejiang Province in 2021. Pol sequences were obtained to determine the subtypes via multiple analytical tools. HIV-1 molecular networks were constructed on the basis of genetic distances to analyze transmission patterns among major subtypes. Furthermore, the birth-death skyline (BDSKY) model was utilized to estimate the transmission risks associated with large clusters (LCs). In 4180 patients, 3699 (88.49%) pol sequences were successfully obtained and classified into four subtype groups. In the networks under an optimal genetic distance of 0.01 substitutions/site, the majority of links (74.52%, 1383/1856) involved individuals within the same city, highlighting the predominant role of local transmission in driving the HIV-1 epidemic. In the CRF07_BC, CRF01_AE, and others/URFs networks, men who have sex with men (MSM) were the primary sexual transmission population, with the younger MSM group (< 30 years old) exhibiting higher linkage frequencies. Within the CRF08_BC network, 93.98% of individuals were infected primarily through heterosexual contact and had a significantly greater risk of localized clustering than other subtypes did. Moreover, fifteen identified LCs were predominantly transmitted through commercial heterosexual contact (CHC), exhibiting localized clustering and high potential for sustained diffusion. Overall, our findings reveal a diverse and heterogeneous distribution of HIV-1 subtypes in Zhejiang Province, with noticeable variations in hotspots across different geographic areas and populations.

Screening Familial Risk for Hereditary Breast and Ovarian Cancer.

Most patients with pathogenic or likely pathogenic (P/LP) variants for breast cancer have not undergone genetic testing. To identify patients meeting family history criteria for genetic testing in the electronic health record (EHR). This study included both cross-sectional (observation date, February 1, 2024) and retrospective cohort (observation period, January 1, 2018, to February 1, 2024) analyses. Participants included patients aged 18 to 79 years enrolled in Renown Health, a large health system in Northern Nevada. Genotype was known for 38 003 patients enrolled in Healthy Nevada Project (HNP), a population genomics study. An EHR indicating that a patient is positive for criteria according to the Seven-Question Family History Questionnaire (hereafter, FHS7 positive) assessing familial risk for hereditary breast and ovarian cancer (HBOC). The primary outcomes were the presence of P/LP variants in the ATM, BRCA1, BRCA2, CHEK2, or PALB2 genes (cross-sectional analysis) or a diagnosis of cancer (cohort analysis). Age-adjusted cancer incidence rates per 100 000 patients per year were calculated using the 2020 US population as the standard. Hazard ratios (HRs) for cancer attributable to FHS7-positive status were estimated using cause-specific hazard models. Among 835 727 patients, 423 393 (50.7%) were female and 29 913 (3.6%) were FHS7 positive. Among those who were FHS7 positive, 24 535 (82.0%) had no evidence of prior genetic testing for HBOC in their EHR. Being FHS7 positive was associated with increased prevalence of P/LP variants in BRCA1/BRCA2 (odds ratio [OR], 3.34; 95% CI, 2.48-4.47), CHEK2 (OR, 1.62; 95% CI, 1.05-2.43), and PALB2 (OR, 2.84; 95% CI, 1.23-6.16) among HNP female individuals, and in BRCA1/BRCA2 (OR, 3.35; 95% CI, 1.93-5.56) among HNP male individuals. Being FHS7 positive was also associated with significantly increased risk of cancer among 131 622 non-HNP female individuals (HR, 1.44; 95% CI, 1.22-1.70) but not among 114 982 non-HNP male individuals (HR, 1.11; 95% CI, 0.87-1.42). Among 1527 HNP survey respondents, 352 of 383 EHR-FHS7 positive patients (91.9%) were survey-FHS7 positive, but only 352 of 883 survey-FHS7 positive patients (39.9%) were EHR-FHS7 positive. Of the 29 913 FHS7-positive patients, 19 764 (66.1%) were identified only after parsing free-text family history comments. Socioeconomic differences were also observed between EHR-FHS7-negative and EHR-FHS7-positive patients, suggesting disparities in recording family history. In this cross-sectional study, EHR-derived FHS7 identified thousands of patients with familial risk for breast cancer, indicating a substantial gap in genetic testing. However, limitations in EHR family history data suggested that other identification methods, such as direct-to-patient questionnaires, are required to fully address this gap.

Two-Stage Adaptive Enrichment Designs with Survival Outcomes and Adjustment for Misclassification in Predictive Biomarkers

Biomarker enrichment clinical trial designs are versatile tools to assess the treatment effect and increase the efficiency of clinical trials. In this article, we propose a two-stage enrichment clinical trial design with survival outcomes, and consider the situation where the biomarker assay and classification are possibly subject to errors. Specifically, the first stage is a randomized design, stratified by the biomarker appeared status. Depending on the result of the interim analysis and a pre-specified futility criterion, the second stage can be either enriched with only the biomarker appeared positive patients, or remain as the stratified design with both biomarker appeared positive and biomarker appeared negative patients. Compared to continuous and binary outcomes, test statistics for survival outcomes to account for biomarker misclassification are much more complicated and require special care. We develop log-rank statistics for the interim and final analyses, with an adjustment for the sensitivity and specificity of the biomarker assay. Control of Type I error rate is achieved by considering correlations between adjusted log-rank statistics from the same and/or different stages. R code is developed to calculate critical values, global/marginal power, and sample size. Our method is illustrated with examples of a recently successful development of immunotherapy in non-small-cell lung cancer.

Eficacy of sulfurous water from Mangalia in Helicobacter Pylori infection: a clinical study

Mangalia balneary resort is situated in the south of the Black Sea and uses sulphurous water springs for rehabilitation therapy. The purpose of this study is to demonstrate the effectiveness of Mangalia sulphurous water on Helicobacter Pylori (H. Pylori) infection. Considering that sulfurous water has a bacteriostatic effect and that most gastritis are caused by H. Pylori infection, we propose that a group of 27 H. Pylori positive patients with or without digestive symptoms ingest sulfurous water daily, for a few days. At the end of the study, 15 of the patients tested negative for H pylori antigen. The curative effects are due to the bacteriostatic effect of sulfurous water and its stimulating action on the digestive tube.

Exploring variations in dengue symptoms: a comparative study of 2013, 2019, and 2023 in a tertiary care hospital of Bangladesh

Background: Dengue fever remains a major public health issue in Bangladesh, with repeated outbreaks. This study compares dengue symptoms in a tertiary care hospital during 2013, 2019, and 2023. The purpose of this study is to evaluate the variations in dengue symptoms among Bangladeshi dengue patients from 2013 and 2019 to 2023. Methods: This was a cross-sectional study, conducted on 100 dengue positive patients, admitted between 1st January to 7th August 2023, to the Medicine Department, Holy Family Red Crescent Medical College and Hospital, Dhaka. Demographic data, sign and symptoms and laboratory investigation reports were collected. These data were compared with a previously published study from the same institute comparing dengue symptoms between 2013 and 2019 among admitted dengue patients. The study employed a convenience sampling method for participant selection, and data analysis was carried out using SPSS version 26. Results: Analysis of 100 sero-positive dengue cases reveals a predominant occurrence in the 20 to 40 age group (51%), with the mean age of patients being 34.5 years. Among these cases, a higher prevalence is observed in males (62%) compared to females (38%). Symptomatology exhibits variations over time, with fever being consistently present. Other symptoms such as headache (90%, 23% and 12%), retroorbital pain (45%, 3% and 16%), skin rash (16%, 4% and 1%) and constipation (32%, 1% and 5%) showing fluctuations, respectively in 2013, 2019 and 2023. Notably, a significant proportion of patients in 2023 exhibit normal ultrasound findings (53%). Conclusions: In conclusion, our study provides a comprehensive analysis of Dengue infection dynamics over a decade, highlighting significant variations in clinical manifestations, laboratory findings, and abdominal ultrasound results among Bangladeshi patients. The findings suggest that Dengue remains a considerable public health concern, with fluctuations observed in symptomatology, including fever and other associated symptoms, and changes in laboratory parameters over time.

Chemokine receptor CXCR4 based positron emission tomography imaging in systemic sclerosis-related interstitial lung disease.

To assess chemokine receptor CXCR4 expression in lung parenchyma and on peripheral immune cells in systemic sclerosis-related interstitial lung disease (SSc-ILD) patients. SSc-ILD patients underwent 68Ga- CPCR4 Trifluoroacetate positron emission tomography (PET) scan, SUVmean in different lung regions and architecturally abnormal areas, and receiver operating characteristic (ROC) curves were analyzed. CXCR4 expression on peripheral immune cells using flow cytometer was studied and correlated with the different lung regions. In addition, subset analysis of CXCR4 expression by clinical subset (early, progressive, stable), ILD pattern and anti-Scl-70 positivity were done. On PET, SSc-ILD patients showed higher median SUVmean uptake of CXCR4 in the whole lung (0.56; p< 0.0001), different lung regions and architecturally abnormal areas than controls. Highest area under curve (AUC) were observed in dorsobasal regions (AUC-0.91; p< 0.0001) and reticular with architecturally distorted areas (AUC-0.95; p< 0.0001). Progressive subset had higher whole lung median SUVmean (0.73) than early (0.49; p< 0.0001) and stable (0.45; p< 0.0001) subsets, and AUC than early and stable subsets. Usual interstitial pneumonia pattern ILD showed higher CXCR4 uptake compared with non-specific interstitial pneumonia (p= 0.0032). Additionally, a trend for higher uptake was noted in anti-Scl70 positive patients as compared with anti-Scl70 negative ones. SSc-ILD patients had higher CD4+CXCR4+T cells (p= 0.0003), and CD8+CXCR4+T cells (p= 0.0013), and showed moderate to strong association on correlation with the lung parenchymal regions. In SSc-ILD, CXCR4 expression is upregulated in both lung parenchyma and peripheral T cells, significantly in progressive and UIP subsets. CXCR4 expression is a potential tool for activity assessment and prognostication.

Portal Vein Thrombosis in COVID-19: An Underdiagnosed Disease?

Background: Multiple studies have linked COVID-19 to a higher incidence of thromboembolic disorders. However, the association of COVID-19 with other potentially life-threatening complications, such as splanchnic vein thrombosis, is less well understood. This study aims to assess the prevalence, patient characteristics, clinical presentation, and outcomes of patients with portal vein thrombosis (PVT) and COVID-19. Methods: This was a retrospective observational study. From all positive patients for a reverse-transcription polymerase chain reaction (RT-PCR) swab test from March 2020 to June 2020, we included those who were older than 18 years, had received abdominal contrast-enhanced computed tomography (CT) in the 6 months following the positive RT-PCR swab, and had no previously known splanchnic vein thrombosis. Results: A total of 60 patients with abdominal CT were selected from all those positive for SARS-CoV-2 (n = 2987). The prevalence of PVT was 3/60 (5%). The mean age was 66.1 ± 16.5 years and 51.7% were male. In two of the three patients, there was no underlying pathology as a risk factor for PVT and one of them presented cirrhosis. The number of days from the start of COVID-19 symptoms until the PVT diagnosis were 21, 12, and 10 days. Anticoagulation treatment achieved recanalization in 100% of cases. During a mean follow-up of 803 days, none of the patients experienced long-term complications. Conclusions: Portal vein thrombosis is uncommon, and its incidence may be higher in COVID-19 patients. A greater understanding of the features of this disease in the context of COVID-19 could aid towards its diagnosis and allow for early detection and management.

Additional predictors of stroke and transient ischaemic attack in BEFAST positive patients in out-of-hours emergency primary care

Introduction In patients suspected of stroke or transient ischemic attack (TIA), rapid triaging is imperative to improve clinical outcomes. For this purpose, balance-eye-face-arm-speech-time (BEFAST) items are used in out-of-hours primary care (OHS-PC). We explored the risk of stroke and TIA among BEFAST positive patients calling to the OHS-PC, and assessed whether additional predictors could improve risk stratification. Methods This is a cross-sectional study of retrospectively gathered routine care data from telephone triage tape-recordings of patients calling the OHS-PC with neurological deficit symptoms, classified as BEFAST positive. Four models–with the predictors age, sex, a history of cardiovascular or cerebrovascular disease, and cardiovascular risk factors–were fitted using logistic regression to predict the outcome stroke or TIA. Likelihood ratio testing was used to select the best model, which was subsequently internally validated. Results The risk of stroke or TIA diagnosis was 52% among 1,289 BEFAST positive patients, median age 72 years, 56% female sex. Of patients with the outcome stroke/TIA, 24% received a low urgency allocation, while 92% had signs or symptoms when calling. Only the addition of age and sex improved predicting stroke or TIA (internally validated c-statistic 0.72, 95%CI 0.69–0.75). The predicted risk of stroke or TIA remained below 20% in those aged below 40. Females aged 70 or over and males aged 55 or over, had a predicted risk above 50%. Discussion Urgency allocation appears to be suboptimal in BEFAST positive patients calling the OHS-PC. Risk stratification could be improved in this setting by adding age and sex.

Efficacy of N-acetylcysteine in reducing inflammation and oxidative stress to prevent complex regional pain syndrome type 1.

This study aimed to evaluate the effectiveness of N-acetylcysteine (NAC) in preventing complex regional pain syndrome type 1 (CRPS-1) by reducing proinflammatory cytokines and oxidative stress markers in patients with distal radius fractures. A retrospective single-center study at Bursa City Hospital involves patients over 50 years of age with distal radius fractures treated between January 2021 and December 2023. A total of 60 patients (mean age, 62.8 ± 5.1 years; 26 males and 34 females) were analyzed. Patients were divided into 2 groups: the NAC group (31 patients receiving 600-mg NAC daily for 3 months) and the control group (29 patients with no prophylactic medication). CRPS-1 diagnosis was based on Budapest criteria during multiple follow-up visits. Serum levels of interleukin (IL)-1 beta, IL-6, tumor necrosis factor-alpha (TNF-α), total oxidant status (TOS), and total antioxidant status (TAS) were measured at baseline and study end point. CRPS-1 positive patients had significantly higher levels of IL-6, TNF-α, and IL-1 (P < .001 for all), higher TOS (P < .001) and oxidative stress index (P < .001), and lower TAS (P < .001) compared with CRPS-1 negatives. The incidence of CRPS-1 was significantly lower in the NAC group (9.7%) compared with the control group (31.0%; P = .039). Logistic regression indicated a 78% reduction in CRPS-1 odds ratio with NAC treatment (odds ratio, 0.219 [95% confidence interval, 0.053-0.895]; P = .0322). NAC significantly reduced end-point levels and changes in IL-6 (P < .001), TNF-α (P < .001), and IL-1 (P = .038) and improved oxidative stress markers, showing higher TAS (P < .001), lower TOS (P < .001), and oxidative stress index (P < .001) compared with controls. NAC significantly reduced the risk of developing CRPS-1 by decreasing levels of proinflammatory cytokines and oxidative stress. This study highlights NAC's potential as a preventive treatment for CRPS-1 and emphasizes the importance of early intervention.

Inetetamab combined with sirolimus and chemotherapy for the treatment of HER2‐positive metastatic breast cancer patients with abnormal activation of the PI3K/Akt/mTOR pathway after trastuzumab treatment

AbstractBackgroundWe explored the efficacy and safety of inetetamab combined with sirolimus and chemotherapy for the treatment of human epidermal factor receptor 2 (HER2)‐positive metastatic breast cancer patients with abnormal activation of the PI3K/Akt/mTOR (PAM) pathway after trastuzumab treatment.MethodsFor this prospective multicenter clinical study, HER2‐positive metastatic breast cancer patients with PAM pathway mutations confirmed by histology or peripheral blood genetic testing were enrolled from July 2021 to September 2022. Patients were randomly assigned to a trial or control group. The patients in the trial group received inetetamab combined with sirolimus and chemotherapy, while the control group patients received pyrotinib and chemotherapy. The RECIST v1.1 standard was used to evaluate efficacy. Descriptive statistics were used to summarize the clinicopathological features, and the Kaplan–Meier method was used to generate survival curves. The log‐rank test was used to compare progression‐free survival (PFS) between the two groups.ResultsA total of 59 HER2‐positive metastatic breast cancer patients with abnormal activation of the PAM pathway were included, of which 37 received inetetamab combined with sirolimus and chemotherapy treatment and 22 received pyrotinib and chemotherapy treatment. The median PFS was 4.64 months in the inetetamab group and 5.69 months in the pyrotinib group, with no statistically significant difference (p = 0.507). The objective response rates were 27.3% for the inetetamab group and 29.4% for the pyrotinib group. The safety assessment indicated that the adverse event (AE) incidences were 86.1% (31/36) in the inetetamab group and 78.9 (15/19) in the pyrotinib group, with 9 (25%) and four (21.1%) Grade 3/4 AEs in the inetetamab and pyrotinib groups, respectively.ConclusionsFor metastatic HER2‐positive breast cancer patients with abnormal PAM pathway activation and previous trastuzumab treatment, the combination of inetetamab with sirolimus and chemotherapy is equivalent to the combination of pyrotinib and chemotherapy. Therefore, this regimen could be a treatment option for PAM pathway‐activated metastatic HER2‐positive breast cancer patients.
