Introduction: Hip fractures are one of the major disability causes associated with a high morbidity and mortality rate. Early surgery and stable fixation could be associated with better pain control, possibly lower mortality rates, and early recovery of autonomy., (This is an open access article distributed under the terms of the Creative Commons Attribution License (CC BY 4.0), which permits unrestricted use, distribution, and reproduction in any medium, provided the original author and source are credited.)

Background: Falls are common adverse events in acute care hospitals, and about 25-50% of fallers suffer injuries. In acute care, fall rates range from 0.4-9 falls per 1000 patient days, varying among unit types, patient characteristics, and diseases. Several risk factors have been identified, including recent falls, age, reduced mobility, cognitive ability and polypharmacy. Several countries have become an aging society in which an increasing number of older patients need acute care. Therefore, the prevention of falls has become one of the most important aspects of patient safety., Aim and Design: This retrospective study aimed to explore adults' inpatient falls in a Finnish university hospital with several specialties. The objectives were to draw an overall picture of fall rates in Finnish acute care, and to model risk factors for falls including secondary diagnoses., Methods: The study was conducted in a large university hospital in Finland. The data consisted of patients' electronic health records from 2014-2016 and included a total of 114,951 adult patients. Univariable and multivariable binary logistic regression model analysis was used to identify risk factors for falls and multiple imputation was used to missing data. The study reporting followed the STROBE guidelines., Results: A total of 841 falls were recorded, totalling 1.5 falls per 1000 patient days, and the rate of falls with injury was 0.4 per 1000 patient days. The regression model included the following risk factors: increasing old age, prolonged hospital stays, specialty of neurology, mode of arrival (emergency care and hospital transfer), no operation during hospital stays and secondary diagnoses such as dementia, pneumonia and alcohol abuse., Conclusions: In acute care, falls occur most in patients with neurological diagnoses and least in surgical patients. Risk factors for falls include increasing age, emergency arrival, hospital transfer and prolonged hospital stay., Relevance to Clinical Practice: Educational interventions to improve healthcare professionals' competence and preventive interventions to avoid inpatient falls need to be prioritized in medical specialties with high fall rates., (© 2022 John Wiley & Sons Ltd.)

Background: There remains a question of whether graduates trained internally are different than those trained elsewhere. We examine the difference between physicians trained within our Graduate Medical Education (GME) programs versus physicians trained elsewhere. Our large integrated healthcare system is unique in addressing this objective due to its large physician labor hiring needs across different specialties of GME graduates., Methods: A retrospective review was performed from Jan 2000 to August 2020 of Kaiser Permanente Southern California (KPSC) physicians hired: KPSC GME trained versus non-KPSC GME trained. We examined five variables: retention, leadership (current or historical), physician relations cases, member appraisal of physician and provider services survey (MAPPS) scores, and rate of board certification. Chi-square test of proportions was used for comparison, p < 0.05 was significant., Results: From Jan 2000 to August 2020, 2940 residents and fellows graduated from KPSC GME programs, of which 1127 (38%) were hired on at KPSC as full time attendings. Across all five metrics (Retention 82% vs 76% (p =  < 0.01), Leadership [current 13% vs 10% (p =  < 0.01)or historical 17% vs 14% (p = 0.01)], Physician Relations 23% vs 26% (p = 0.04), MAPPS 75% vs 69% (p =  < 0.01), and Board Certification 81% vs 74% (p =  < 0.01)), KPSC outperformed non-KPSC GME-trained physicians to a statistically significant degree., Conclusions: We have shown that an internally sponsored GME program can represent an opportunity for recruitment of physicians that may have higher retention rates, higher probability of being physician leaders, decreased likelihood of physician relations issues, improved patient satisfaction, and increased rates of board certification., (© 2023.

Background Diuretic resistance is associated with increased mortality in patients with heart failure (HF). Qi Li Qiang Xin Jiao Nang, a Traditional Chinese Medicine, are used in the treatment of HF. However, clinical evidence of their effectiveness in improving diuretic resistance is lacking. Objective To investigate whether Qi Li Qiang Xin Jiao Nang can reduce the risk of diuretic resistance and improve prognosis in patients with acute decompensated chronic heart failure (ADCHF) . Methods This study included 374 HF patients treated in the CICU ward of Tianjin University Chest Hospital from January 2018 to June 2022. Patients were divided into diuretic resistance (118 patients) and non-diuretic resistance groups (256 patients) based on the occurrence of diuretic resistance. Patient data and laboratory results were collected. A 12-month follow-up was conducted to observe rehospitalization due to cardiovascular events or all-cause mortality. Kaplan-Meyer survival curves were plotted for each group, and the Log-rank test was used for comparison. Multivariate Logistic regression analysis was performed to explore factors influencing diuretic resistance. Multivariable Cox regression analysis was used to explore factors affecting the occurrence of endpoint events in ADCHF patients. Results The diuretic resistance group showed higher age, body mass, NT-proBNP, blood urea nitrogen, creatinine, uric acid, and international normalized ratio (INR) but lower 24-hour fluid intake, estimated glomerular filtration rate (eGFR), lymphocyte count, and usage of Qi Li Qiang Xin Jiao Nang. Multivariate Logistic regression analysis indicated that the use of Qi Li Qiang Xin Jiao Nang (OR=0.363, 95%CI=0.186-0.708, P=0.003) and increased 24-hour fluid intake (OR=0.286, 95%CI=0.177-0.461, P

Objectives: To evaluate the success rate of bone grafts and implants carried out at the Latin American Institute for Research and Dental Education (ILAPEO), considering the following: (i) the different pure bone substitutes (autogenous, xenogeneic, and alloplastic), (ii) the presurgical bone height, and (iii) how the treatment is compromised when membrane perforation occurs during sinus lift in maxillary sinus surgeries. Material and Methods . The initial sample comprised 1040 records of maxillary sinus lifting surgeries. After evaluation, the final sample retained 472 grafts performed using the lateral window technique with a total of 757 implants. The grafts were divided into 3 groups: (i) autogenous bone ( n = 197), (ii) xenogenous bovine bone ( n = 182), and (iii) alloplastic material ( n = 93). One calibrated examiner classified the sample into two groups based on the residual bone height (<4 mm and ≥4 mm) of the area of interest measured on parasagittal sections of tomographic images. Data on membrane perforation occurrences in each group were collected; qualitative variables were described using frequency, expressed as percentages. The Chi-square test was used to analyze the success of the graft types and the survival rate of the implants as a function of the grafted material and the residual bone height. The Kaplan-Meier survival analysis was used to calculate the survival rate of bone grafts and implants according to the classifications adopted in this retrospective study., Results: The success rate of grafts and implants was 98.3% and 97.2%, respectively. There was no statistically significant difference in the success rate among the different bone substitutes ( p = 0.140). Only 8 grafts (1.7%) and 21 implants (2.8%) failed. There was a greater success rate for both grafts (96.5%) and implants (97.4%) when the bone height was ≥4 mm. The success rate in the 49 sinuses in which the membrane was perforated was 97.96% for the grafts and 96.2% for the implants. The follow-up periods after rehabilitation ranged from 3 months to 13 years., Conclusions: Within the limitations of the data analyzed in this retrospective study, maxillary sinus lift was a viable surgical technique that enabled implant placement with a predictable long-term success rate, regardless of the type of material used. The presence of membrane perforation did not interfere with the success rate obtained for grafts and implants., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2023 Vanessa Helena Jamcoski et al.)

Dental general anesthesia (DGA) can be a preferred approach for treating children with special health needs (CSHCN). It has many benefits, most importantly, the support of the anesthesia team to control the medical status and treat the patient safely. The aim of this study was to evaluate the dental treatment provided to (CSHCN) under (DGA) in a tertiary-care hospital. Moreover, to compare the dental procedures between different medical conditions. This retrospective study involves a sample of 730 children aged between (1–16 years) with complex medical conditions treated under DGA between January 2009 until April 2022. The results show that 4.93 % of these patients had DGA twice. For those children who had DGA only once, the most frequent medical conditions were neuro-developmental disorders (31.8 %), pediatric oncology (17.4 %), and behavioral disorders (autism, ADHD, etc.) (15.1 %). The average age was 6.9 years; almost half were preschool children (4–6 years old, 48.41 %) followed by younger school children (7–9 years old, 28.82 %). The most common dental procedures done were extractions followed by restorative procedures. The use of fissure sealant was significantly higher in neuro-developmental and behavioral disabilities patients than other medical conditions.

Abstract Tuberculosis (TB) remains a significant public health concern, particularly in low-resource settings. The treatment outcome is a crucial indicator of the effectiveness of TB treatment programs. Assessing the current treatment outcome and its associated factors is essential for improving patient care and reducing the spread of TB. Therefore, this study aimed to assess TB treatment outcomes and their associated factors among TB patients who received treatment at public healthcare facilities in Motta Town, Northwest Ethiopia. A facility-based retrospective cross-sectional study design was employed in two TB treatment centers in Motta town from January 2017 to December 2021. The study participants were all patients diagnosed with TB who received treatment. A p-value of 0.05 with a 95% confidence interval (CI) was used to determine statistical significance. A total of 362 TB patients were included in the study. The overall treatment success rate was 88.4% (95% CI 85.1, 91.7). Male gender (AOR = 2.40, 95% CI 1.16, 4.98), normal nutritional status (AOR = 3.11, 95% CI 1.33, 7.25), HIV negative status (AOR = 3.35, 95% CI 1.31, 8.60), and non-presumptive drug resistance to TB (AOR = 3.72, 95% CI 1.74, 7.98) were significantly associated with successful TB treatment outcomes (p

Abstract Dupilumab is a biologic medication that is used for the treatment of moderate-to-severe atopic dermatitis (AD). Long-term data on dupilumab drug survival in Asia patients with AD are limited. A single-center, retrospective study was performed to assess drug survival between March 2019 and March 2023. Drug survival and associated characteristics were analyzed using Kaplan–Meier survival curves and multivariate Cox regression analysis, respectively. A total of 124 patients with AD (Mean age [standard deviation], 26.0 [8.6] years) with a 4 years-overall dupilumab drug survival rate of 87.9%, were included in this study. Characteristics associated with shorter drug survival were the low eczema area and severity index (EASI) scores at baseline (hazard ratio [HR] 0.84; 95% confidence interval [CI] 0.75–0.94, p-value = 0.003) and non-insurance coverage of dupilumab (HR 11.87; 95% CI 3.28–42.99, p-value = 0.001). This retrospective study demonstrated good overall 4-year dupilumab survival (87.6%) in South Korea. Patients with low baseline EASI scores and those who did not have insurance for dupilumab treatment discontinued the therapy frequently. To the best of our knowledge, this is the first long-term dupilumab drug survival study conducted in Asia with predictors.

Background: Patient-clinician secure messaging is an important function in patient portals and enables patients and clinicians to communicate on a wide spectrum of issues in a timely manner. With its growing adoption and patient engagement, it is time to comprehensively study the secure messages and user behaviors in order to improve patient-centered care., Objective: The aim of this paper was to analyze the secure messages sent by patients and clinicians in a large multispecialty health system at Mayo Clinic, Rochester., Methods: We performed message-based, sender-based, and thread-based analyses of more than 5 million secure messages between 2010 and 2017. We summarized the message volumes, patient and clinician population sizes, message counts per patient or clinician, as well as the trends of message volumes and user counts over the years. In addition, we calculated the time distribution of clinician-sent messages to understand their workloads at different times of a day. We also analyzed the time delay in clinician responses to patient messages to assess their communication efficiency and the back-and-forth rounds to estimate the communication complexity., Results: During 2010-2017, the patient portal at Mayo Clinic, Rochester experienced a significant growth in terms of the count of patient users and the total number of secure messages sent by patients and clinicians. Three clinician categories, namely "physician-primary care," "registered nurse-specialty," and "physician-specialty," bore the majority of message volume increase. The patient portal also demonstrated growing trends in message counts per patient and clinician. The "nurse practitioner or physician assistant-primary care" and "physician-primary care" categories had the heaviest per-clinician workload each year. Most messages by the clinicians were sent from 7 AM to 5 PM during a day. Yet, between 5 PM and 7 PM, the physicians sent 7.0% (95,785/1,377,006) of their daily messages, and the nurse practitioner or physician assistant sent 5.4% (22,121/408,526) of their daily messages. The clinicians replied to 72.2% (1,272,069/1,761,739) patient messages within 1 day and 90.6% (1,595,702/1,761,739) within 3 days. In 95.1% (1,499,316/1,576,205) of the message threads, the patients communicated with their clinicians back and forth for no more than 4 rounds., Conclusions: Our study found steady increases in patient adoption of the secure messaging system and the average workload per clinician over 8 years. However, most clinicians responded timely to meet the patients' needs. Our study also revealed differential patient-clinician communication patterns across different practice roles and care settings. These findings suggest opportunities for care teams to optimize messaging tasks and to balance the workload for optimal efficiency., (©Ming Huang, Jungwei Fan, Julie Prigge, Nilay D Shah, Brian A Costello, Lixia Yao.

Aim: To investigate the clinical features, diagnosis and treatment of lymphoepithelioma-like carcinoma (LELC).Materials & methods: The clinical data of 114 LELC patients were retrospectively analyzed.Results: Ninety-eight patients (86.0%) were Epstein-Barr virus-encoded small RNA (EBER) positive detected by situ hybridization. A 67.1% (51/76) patients had PD-L1 expression. The 5-year overall survival rate of EBER negative patients was 51.6% while the rate of positive patients was 84.8% (p = 0.015). The 5-year progression free survival rate of EBER negative patients was 40.2% while the rate of positive patients was 70.2% (p = 0.004).Conclusion: The progression of LELC is relatively slow and present a better prognosis. The occurrence of tumor is closely related to Epstein–Barr virus infection and PD-L1 is highly expressed in tumor cells.

Abstract Pediatric trauma plays a crucial role in pediatric mortality, with traffic injuries and falls frequently cited as leading causes of significant injuries among children. A comprehensive investigation, including geographical factors, is essential for developing effective strategies to prevent injuries and alleviate the burden of pediatric trauma. This study involved a retrospective analysis of clinical data from pediatric patients admitted to our hospital’s intensive care unit (ICU) due to trauma over a 10-year period. Comprehensive analyses were conducted to elucidate trends, demographics, injury patterns, and risk factors associated with these admissions. This retrospective study included 951 pediatric patients (mean age: 4.79 ± 3.24 years; mean weight: 18.45 ± 9.02 kg; median time to ICU admission post-injury: 10.86 ± 14.95 h). Among these patients, 422 (44.4%) underwent emergency surgery, and 466 (49%) required mechanical ventilation support, with a mean duration of 70.19 ± 146.62 h. The mean duration of ICU stay was 6.24 ± 8.01 days, and the overall mean hospitalization duration was 16.08 ± 15.56 days. The predominant cause of unintentional injury was traffic accidents (47.9%), followed by falls (42.5%) and burns/scalds (5.3%). Most incidents involved children aged 0–6 years (70.7%), with males comprising 60.0% of patients. Injury incidents predominantly occurred between 12 and 6 PM (44.5%) and on non-workdays (37.6%). The most common locations where injuries occurred were roadsides (49%) and rural areas (64.35%). Single-site injuries (58.78%) were more prevalent than multiple-site injuries (41.22%), and head injuries were the most common among single-site injuries (81.57%). At ICU admission, the mean injury severity score was 18.49 ± 8.86. Following active intervention, 871 patients (91.59%) showed improvement, while 80 (8.41%) succumbed to their injuries. Traffic injuries remain the primary cause of pediatric trauma leading to ICU admission, underscoring the importance of using appropriate child restraint systems and protective gear as fundamental preventive measures. The increased incidence of injuries among children aged

Abstract Colonoscopies are widely available, but there are cases where insertion can be difficult, even for experienced endoscopists. EC-760XP/L, a new ultrasmall-diameter long scope, may be useful in such cases. This single-center retrospective study included 39 cases where colonoscope insertion was difficult even when previously conducted by an experienced endoscopist. The primary outcome was the cecal intubation time using EC-760XP/L compared to the time used in a previous examination with a standard scope. The secondary outcomes were the cecum intubation rate, intestinal cleanliness level, adenoma detection rate, polyp detection rate, sedative use rate, occurrence of adverse events, and pain experience. A comparison of cecal intubation times between EC-760XP/L and the standard scope showed that insertion times were significantly lower with EC-760XP/L (9.5 min) compared to the standard scope (19 min) (p

Background: Data on balloon-assisted techniques (BAT) for transcatheter closure (TCC) of ostium secundum atrial septal defect (ASD-II) is scarce. The objective was to study the outcomes of the balloon-assisted technique (BAT) for transcatheter closure (TCC) of ostium secundum atrial septal defect. A single-centre retrospective study of patients with ostium secundum ASD who underwent balloon-assisted TCC. Results: This study included 36 patients. Thirty-three out of 36 patients with ASD-II and complex morphological features underwent successful BAT TCC. Our cohort of patients had a high prevalence of inadequate/floppy Aortic (90%), Posterior (40%) and Superior/Right upper pulmonary vein (25%) rims. Procedural success was defined as stable device position on post-procedure echocardiogram at 24-48 hours with no residual shunt. BAT was successful in 33 out of 36 patients (91.6%). The mean ASD size with BAT success was 27 mm. BAT was unsuccessful in 3 out of 36 patients. The combined deficiency and floppy nature of the Aortic, Superior, and Posterior rims was the reason for the failure of the Balloon-assisted technique along with the large size of ASD-II. BAT-failed patients were referred for emergent surgical device retrieval and closure of the atrial septal defect. No procedure-related mortality was encountered. Conclusions: Balloon-assisted device closure of ASD had a 90% success rate. BAT is a safe and effective technique in patients with large ASD-II. This technique enables controlled device delivery and alignment when conventional techniques fail.

Abstract The aim of this study was to compare the changes in the sagittal pharyngeal airway dimension (SPAD) in adolescents with Class II mandibular retrusion treated with Invisalign Mandibular Advancement (IMA), prefabricated Myobrace (MB), and Twin block (TB). For this retrospective study, the pre-treatment and post-treatment lateral cephalograms of 60 patients who underwent myofunctional treatment, using either one of the tested appliances were gathered from the files of treated patients. Changes in the SPAD were measured in each group, and comparisons were carried out between the three study groups. Additionally, sagittal skeletal measurements were carried out. Comparisons of the study variables at T0 and T1 between the three groups were performed using one-way ANOVA, while comparisons of the difference (T1–T0) were performed using Kruskal Wallis test. A significant SPAD increase has been reported using the three tested appliances (p 0.05). The IMA, MB, and TB generated significant SPAD and sagittal changes, with both IMA and TB surpassing MB in the airway area improvement post-treatment. Moreover, the three tested Class II functional appliances did not affect the vertical dimension.

Background: Fine needle aspiration cytology (FNAC) is an important diagnostic modality in palpable breast lesions. This together with imaging modality is important in distinguishing benign from malignant lesions of the breast. Granulomatous/inflammatory mastitis forms a small subset of breast lesions that may present as a breast lump. Clinical and radiological features in these cases may mimic malignant breast pathology. Aims and Objectives: The aim of this study was to study the frequency of granulomatous mastitis and other inflammatory mastitis with respect to other neoplastic lesions of the breast, presented in FNAC clinics and to correlate the cytological findings with the clinical presentation of granulomatous and other inflammatory mastitis. Materials and Methods: A retrospective study was conducted in the Department of Pathology in a tertiary care center in Eastern India for duration of 4 years 5 months. Details of all patients who underwent FNAC for breast lesions during the study period were recorded in terms of their clinical presentation, cytological findings, imaging, and ancillary investigations. The findings were then tabulated in a master sheet and analysis done by descriptive statistics using SPSS 25. Results: A total of 154 cases were included with 5 cases (3.2%) of granulomatous and 12 cases (7.8%) of inflammatory mastitis. Age range for granulomatous/inflammatory mastitis was 20–70 years. Lump and pain were the most common complaints followed by inflammatory skin changes and nipple discharge. Very few cases also showed nipple retractions and very occasional systemic symptoms like fever. History of lactation was seen among five cases. Three cases showed positive acid-fast bacilli in Ziehl–Neelsen stain. Radiology was discordant with cytological findings in three cases, where the former suggested a breast neoplastic process. Conclusion: Granulomatous/inflammatory mastitis is a rarely diagnosed entity in breast cytopathology with no standard guidelines for management. Antibiotics antitubercular therapy and corticosteroids are some proposed lines of medical management. In treatment-resistant cases, wide local excision may be done depending on available resources and surveillance opportunities.

Human infections with Corynebacterium diphtheriae species complex (CdSC) bacteria were rare in French Guiana until 2016, when the number of cases diagnosed increased. We conducted an epidemiologic, multicenter, retrospective study of all human CdSC infections diagnosed in French Guiana during January 1, 2016–December 31, 2021. A total of 64 infectious episodes were observed in 60 patients; 61 infections were caused by C. diphtheriae and 3 by C. ulcerans. Estimated incidence increased from 0.7 cases/100,000 population in 2016 to 7.7 cases/100,000 population in 2021. The mean patient age was 30.4 (+23.7) years, and male-to-female ratio was 1.7:1 (38/22). Of the 61 C. diphtheriae isolates, 5 tested positive for the diphtheria toxin gene, and all results were negative by Elek test; 95% (61/64) of cases were cutaneous, including the C. ulcerans cases. The increase in reported human infections underscores the need to raise awareness among frontline healthcare practitioners to improve prevention.

Abstract We conducted a retrospective study to investigate risk factors for tuberculosis care-seeking delay and diagnostic delays among pediatric pulmonary tuberculosis cases in Zhejiang Province from 2013 to 2022. Among 1274 cases, 49.61% experienced tuberculosis care-seeking delays (> 14 days from symptom onset to first hospital visit) and 14.91% faced diagnostic delays (> 14 days from initial consultation to diagnosis). The proportion of care-seeking delays ranged from 37.42 to 64.89%, while diagnostic delay fluctuated from 6.11 to 21.02%. Urban residence (OR = 0.78, 95% CI 0.62–0.98, P = 0.030), first visiting a municipal-level hospital (OR = 0.57, 95% CI 0.45–0.72, P

Objective: Sentinel lymph node (SLN) dissection is a highly accurate surgical procedure allowing detection of lymph node invasion in patients with clinically negative axilla in early breast cancer. Superparamagnetic iron oxide (SPIO) is a marker used during SLN procedure, allowing the same detection rate as isotopes (Tc-99). A drawback of SPIO is skin staining that can occur around the injection site. The goal of this retrospective study was to assess the frequency of skin staining after oncological breast surgery with SPIO, and the impact of two different injection protocols on the rate of skin staining. Materials and Methods: Data from breast cancer patients undergoing magnetic tracer SLN detection (SLND) procedure in a single department between 2020 and 2022 was reviewed. Injection protocol P1 consisted of retro-areolar injection of Magtrace 0.8 mL. Injection protocol P2, consisted of retro-tumoral injection with 1 mL. Presence of skin staining was assessed at day 10 after surgery. The evolution and satisfaction of the patients was assessed at six and 12 months. Results: In total 175 sentinel lymph node biopsy procedures were performed (P1: 141/P2: 34), consisting of breast conservative surgery (BCS) (P1: 70%/P2: 53%) or mastectomy (P1: 30%/P2: 47%) with SLN. SLN detection rate was 97.7%. Skin staining was reported in 23% and occurred more often after BCS (31.6%) compared to mastectomy (6.8%). When BCS was performed, peritumoral injection was associated with a decreased risk of skin staining compared with retro-areolar injection (22.2% vs. 33.3%, respectively). When present skin staining persisted for 12 months, but most of the patients described only a slight discomfort. The low rate of discoloration after mastectomy, as previously reported, can be explained by the removal of skin and glandular tissue in which the tracer accumulates. Less skin staining in P2 may be because of a shorter interval between injection and surgery and the removal of the excess of SPIO during the lumpectomy. Conclusion: SPIO injection is a safe surgical technique. After mastectomy, the rate of discoloration was low. Despite the persistent skin discoloration in 58.6% in our study, patient satisfaction was high. Deeper injection, reduced doses, massage of the injection site and peritumoral injection may reduce skin staining.

Abstract This study aimed to develop and internally validate a nomogram model for assessing the risk of intraoperative hypothermia in patients undergoing video-assisted thoracoscopic (VATS) lobectomy. This study is a retrospective study. A total of 530 patients who undergoing VATS lobectomy from January 2022 to December 2023 in a tertiary hospital in Wuhan were selected. Patients were divided into hypothermia group (n = 346) and non-hypothermia group (n = 184) according to whether hypothermia occurred during the operation. Lasso regression was used to screen the independent variables. Logistic regression was used to analyze the risk factors of hypothermia during operation, and a nomogram model was established. Bootstrap method was used to internally verify the nomogram model. Receiver operating characteristic (ROC) curve was used to evaluate the discrimination of the model. Calibration curve and Hosmer Lemeshow test were used to evaluate the accuracy of the model. Decision curve analysis (DCA) was used to evaluate the clinical utility of the model. Intraoperative hypothermia occurred in 346 of 530 patients undergoing VATS lobectomy (65.28%). Logistic regression analysis showed that age, serum total bilirubin, inhaled desflurane, anesthesia duration, intraoperative infusion volume, intraoperative blood loss and body mass index were risk factors for intraoperative hypothermia in patients undergoing VATS lobectomy (P

Abstract Adjuvant oxaliplatin plus S-1 (SOX) chemotherapy for gastric cancer (GC) after D2 gastrectomy has been proven effective. There has yet to be a study that evaluates adjuvant nanoparticle albumin-bound paclitaxel (nab-paclitaxel) plus S-1. In this single-center, retrospective study, GC patients after D2 gastrectomy received either nab-paclitaxel plus S-1 (AS group) or SOX group were recruited between January 2018 and December 2020 in The First Affiliated Hospital of Zhejiang University. Intravenous nab-paclitaxel 120 mg/m2 or 260 mg/m2 and oxaliplatin 130 mg/m2 were administered as eight 3 week cycle, especially in the AS and SOX group. Patients received S-1 twice daily with a dose of 40 mg/m2 in the two groups on days 1–14 of each cycle. The end points were disease-free survival (DFS) rate at 3 years and adverse events (AEs). There were 56 eligible patients, 28 in the AS group and 35 in the SOX group. The 3 year DFS rate was 78.0% in AS group versus 70.7% in SOX group (p = 0.46). Subgroup analysis showed that the patients with signet-ring positive in the AS group had a prolonged DFS compared with the SOX group (40.0 vs. 13.8 m, p = 0.02). The diffuse-type GC or low differentiation in the AS group was associated with numerically prolonged DFS compared with the SOX group, but the association was not statistically significant (p = 0.27 and p = 0.15 especially). Leukopenia (14.3%) were the most prevalent AEs in the AS group, while thrombocytopenia (28.5%) in the SOX group. Neutropenia (7.1% in AS group) and thrombocytopenia (22.8% in SOX group) were the most common grade 3 or 4 AEs. In this study analyzing past data, a tendency towards a greater 3 year DFS was observed when using AS regimen in signet-ring positive patients. AS group had fewer thrombocytopenia compared to SOX group. More studies should be conducted with larger sample sizes.

Objective: Benign fibroosseous lesions (BFOLs) encompass a heterogenous collection of bone conditions characterized by replacing normal bone with fibro-collagenous tissue with osteoid or woven bone, and cementicles. Despite their clinical significance, the frequency of BFOLs in Saudi Arabia still needs to be assessed. Methods: This retrospective study investigated the frequency and demographics of BFOLs in Riyadh, Saudi Arabia, by retrieving all cases recorded between January 1984 and January 2013 from a single Oral Pathology Laboratory archive. Results: A total of 64 cases were classified as BFOLs, with a predominance in females (67.2 %) and a median age of 21.5 years. The most prevalent condition identified was fibrous dysplasia (45.31 %), followed by cemento-ossifying fibroma (26.56 %). There were significant sex differences between BFOLs, with a p-value of 0.03. FD was predominantly located in the maxilla (65.5 %), whereas COF was predominantly found in the mandible (82.3 %). Recurrence was observed in 17.2 % of patients with FD, in contrast to no reported recurrence in patients with COF. Conclusion: This study represents the first exploration of BFOL frequency and demographics in Riyadh, Saudi Arabia, highlighting the need for further investigations to comprehensively understand the nature of these lesions in our population.

Abstract Controversy still exists regarding how much the inflow arterial percutaneous transluminal angioplasty (PTA) contributed to maintaining fistula function for hemodialysis. We aimed to analyze patency and risk factors after inflow arterial PTA. Hemodialysis patients with inflow arterial primary stenosis who were admitted to our institution from January 2017 to December 2022 were examined. One group had arterial-venous fistula with inflow artery stenosis alone (AVF + iAS) and another group had AVF with inflow artery stenosis and any vein stenosis (AVF + iAS + VS). The characteristics of patients, stenotic lesions, and PTA procedures were recorded. Kaplan–Meier analysis was used to compare primary patency, assisted primary patency, and secondary patency in the two groups. Cox proportional hazard analysis was used to identify risk factors associated with patency. We examined 213 patients, 53 in the AVF + iAS group (51 radial arterial stenosis and 2 ulnar arterial stenosis) and 160 in the AVF + iAS + VS group (159 radial arterial stenosis and 1 ulnar arterial stenosis). Kaplan–Meier analysis indicated the AVF + iAS group had better primary patency and assisted primary patency (both P

Abstract This study investigated whether machine learning (ML) has better predictive accuracy than logistic regression analysis (LR) for gait independence at discharge in subacute stroke patients (n = 843) who could not walk independently at admission. We developed prediction models using LR and five ML algorithms—specifically, the decision tree (DT), support vector machine, artificial neural network, ensemble learning, and k-nearest neighbor methods. Functional Independence Measure sub-items were used to evaluate the ability to walk independently. Model predictive accuracies were evaluated using areas under receiver operating characteristic curves (AUCs) as well as accuracy, precision, recall, F1 score, and specificity. The AUC for DT (0.812) was significantly lower than those for the other algorithms (p

Abstract Although COVID-19 infection is an immunosuppressant disease, many immunosuppressant agents, such as pulse methylprednisolone (PMP), dexamethasone (DXM), and tocilizumab (TCZ), were used during the pandemic. Secondary infections in patients with COVID-19 have been reported recently. This study investigated these agents’ effects on secondary infections and outcomes in patients with COVID-19 in intensive care units (ICUs). This study was designed retrospectively, and all data were collected from the tertiary intensive care units of six hospitals between March 2020 and October 2021. All patients were divided into three groups: Group I [GI, PMP (−), DXM (−) and TCZ (−)], Group II [GII, PMP (+), DXM (+)], and Group III [GIII, PMP (+), DXM (+), TCZ (+)]. Demographic data, PaO/FiO2 ratio, laboratory parameters, culture results, and outcomes were recorded. To compare GI-GII and GI-GIII, propensity score matching (PSM) was used by matching 14 parameters. Four hundred twelve patients with COVID-19 in the ICU were included in the study. The number of patients with microorganisms ≥ 2 was 279 (67.7%). After PSM, in GII and GIII, the number of (+) tracheal cultures and (+) bloodstream cultures detected different microorganisms ≥ 2 during the ICU period, neuropathy, tracheotomized patients, duration of IMV, and length of ICU stay were significantly higher than GI. The mortality rate was similar in GI and GII, whereas it was significantly higher in GIII than in GI. The use of immunosuppressant agents in COVID-19 patients may lead to an increase in secondary infections. In addition, increased secondary infections may lead to prolonged ICU stay, prolonged IMV duration, and increased mortality.

Abstract Background Few studies have quantified multimorbidity and frailty trends within hospital settings, with even fewer reporting how much is attributable to the ageing population and individual patient factors. Studies to date have tended to focus on people over 65, rarely capturing older people or stratifying findings by planned and unplanned activity. As the UK’s national health service (NHS) backlog worsens, and debates about productivity dominate, it is essential to understand these hospital trends so health services can meet them. Methods Hospital Episode Statistics inpatient admission records were extracted for adults between 2006 and 2021. Multimorbidity and frailty was measured using Elixhauser Comorbidity Index and Soong Frailty Scores. Yearly proportions of people with Elixhauser conditions (0, 1, 2, 3 +) or frailty syndromes (0, 1, 2 +) were reported, and the prevalence between 2006 and 2021 compared. Logistic regression models measured how much patient factors impacted the likelihood of having three or more Elixhauser conditions or two or more frailty syndromes. Results were stratified by age groups (18–44, 45–64 and 65 +) and admission type (emergency or elective). Results The study included 107 million adult inpatient hospital episodes. Overall, the proportion of admissions with one or more Elixhauser conditions rose for acute and elective admissions, with the trend becoming more prominent as age increased. This was most striking among acute admissions for people aged 65 and over, who saw a 35.2% absolute increase in the proportion of admissions who had three or more Elixhauser conditions. This means there were 915,221 extra hospital episodes in the last 12 months of the study, by people who had at least three Elixhauser conditions compared with 15 years ago. The findings were similar for people who had one or more frailty syndromes. Overall, year, age and socioeconomic deprivation were found to be strongly and positively associated with having three or more Elixhauser conditions or two or more frailty syndromes, with socioeconomic deprivation showing a strong dose–response relationship. Conclusions Overall, the proportion of hospital admissions with multiple conditions or frailty syndromes has risen over the last 15 years. This matches smaller-scale and anecdotal reports from hospitals and can inform how hospitals are reimbursed.

Abstract Background Assessing dietary phenylalanine (Phe) tolerance is crucial for managing hyperphenylalaninemia (HPA) in children. However, traditionally, adjusting the diet requires significant time from clinicians and parents. This study aims to investigate the development of a machine-learning model that predicts a range of dietary Phe intake tolerance for children with HPA over 10 years following diagnosis. Methods In this multicenter retrospective observational study, we collected the genotypes of phenylalanine hydroxylase (PAH), metabolic profiles at screening and diagnosis, and blood Phe concentrations corresponding to dietary Phe intake from over 10 years of follow-up data for 204 children with HPA. To incorporate genetic information, allelic phenotype value (APV) was input for 2965 missense variants in the PAH gene using a predicted APV (pAPV) model. This model was trained on known pheno-genotype relationships from the BioPKU database, utilizing 31 features. Subsequently, a multiclass classification model was constructed and trained on a dataset featuring metabolic data, genetic data, and follow-up data from 3177 events. The final model was fine-tuned using tenfold validation and validated against three independent datasets. Results The pAPV model achieved a good predictive performance with root mean squared error (RMSE) of 1.53 and 2.38 on the training and test datasets, respectively. The variants that cause amino acid changes in the region of 200–300 of PAH tend to exhibit lower pAPV. The final model achieved a sensitivity range of 0.77 to 0.91 and a specificity range of 0.8 to 1 across all validation datasets. Additional assessment metrics including positive predictive value (0.68–1), negative predictive values (0.8–0.98), F1 score (0.71–0.92), and balanced accuracy (0.8–0.92) demonstrated the robust performance of our model. Conclusions Our model integrates metabolic and genetic information to accurately predict age-specific Phe tolerance, aiding in the precision management of patients with HPA. This study provides a potential framework that could be applied to other inborn errors of metabolism.

The efficacy of artificial neural network (ANN) models employing laboratory variables for predicting fatty liver disease (FLD) remains inadequately established. The study aimed to develop ANN models to precisely predict FLD.

Abstract The aim of this study was to investigate the effect of zoledronic acid (ZA) on postoperative healing and functional rehabilitation in osteoporotic patients with rotator cuff (RC) injury. 96 Patients were divided into three groups according to bone mineral density and ZA use (Group A: normal BMD; Group B: osteoporosis and intravenous ZA use; Group C: osteoporosis, without ZA use). Radiologic, functional and Serological outcomes were evaluated 6 months after surgery. The functional scores in all groups exhibited significant improvement 6 months after surgery. Inter-group comparison showed that Constant Shoulder joint function Score (CSS) of group A not significantly differing from that of group B, the other indicators were significantly better than those of group B and C. There were no significant differences in shoulder forward flexion, abductive Range of Motion between group B and C. Other indicators of group B were significantly improved compared to group C. The retear rate in group C (30.3%, 10/33) was higher than group A (6.1%, 2/33) and group B (13.3%, 4/30). In conclusion, the application of ZA can significantly reduce the rate of RC retear in elderly patients with osteoporosis after surgery, which is significant for postoperative shoulder joint functional rehabilitation.

Abstract This study aimed to develop a predictive tool for surgical site infections (SSI) following hysterectomy and propose strategies for their prevention and control. We conducted a retrospective analysis at a tertiary maternity and child specialist hospital in Zhejiang Province, focusing on patients who underwent hysterectomy between January 2018 and December 2023 for gynecological malignancies or benign reproductive system diseases resistant to medical treatment. Risk factors associated with surgical site infections (SSI) following hysterectomy were identified using LASSO regression analysis on data from 2018 to 2022 as the training set. Independent risk factors were then used to develop a nomogram. The model was validated using data from 2023 as the validation set. Model performance was assessed using the area under the receiver operating characteristic curve (ROC), while calibration curves were employed to gauge model accuracy. Furthermore, clinical utility was evaluated through clinical decision curve analysis (DCA) and clinical impact curve analysis (CIC), providing insights into the practical application of the nomogram. Multivariate analysis identified six independent risk factors associated with SSI development after hysterectomy: BMI ≥ 24 kg/m2 (OR: 2.58; 95% CI 1.14–6.19; P

Abstract. Background:. Endoscopic papillectomy (EP) is recommended as the first-line therapy for ampullary tumors, despite a relatively high incidence of complications. Pancreatic and/or biliary stents are placed at the endoscopist's discretion to prevent post-EP complications. The present study aimed to evaluate the efficacy of different stents. Methods:. A total of 117 patients who underwent EP and met the criteria between June 2006 and October 2022 were enrolled in the study. These patients were divided into a pancreatic stent group (PS group, n = 47), a biliary stent group (BS group, n = 38), and a two-stent group (PBS [PS and BS] group, n = 32). Relevant clinical data were collected and compared among the three groups. Multivariate logistic analyses were performed to explore risk factors for post-EP complications. Results:. The incidence of all complications was 37.6% (44/117). Pancreatitis and hemorrhage were the two most common complications with incidence rates of 14.5% (17/117) and 17.9% (21/117). The incidence rates of post-EP pancreatitis were 10.6% (5/47), 23.7% (9/38), and 9.4% (3/32) in the PS group, BS group, and PBS group, respectively, with no significant differences. There were also no significant differences in other complications among the three groups. Age (odds ratio [OR]: 0.95; 95% confidence interval [CI]: 0.91–0.99; P = 0.022) was independently associated with post-EP pancreatitis while tumor size (OR: 1.66; 95% CI: 1.06–2.60; P = 0.028) was independently associated with post-EP hemorrhage. Conclusions:. While pancreatic stenting is the first choice to prevent post-EP pancreatitis, biliary stenting could also be considered as a substitute for patients with difficulties in pancreatic cannulation. Two-stent (biliary and pancreatic stent) placement is unnecessary unless it is required due to other concerns.

Background Acute pulmonary embolism (APE) is a serious cardiovascular disease. In recent years, there has been an increasing detection rate of patients with APE accompanied by thrombocytopenia, presenting a dual challenge of thrombosis and bleeding. Current research is mainly based on successful case reports, with a certain research gap in clinical evaluation and treatment options. Objective To explore the clinical characteristics and prognosis of APE patients complicated with thrombocytopenia, so as to provide a basis for clinical diagnosis and treatment. Methods A total of 21 patients with APE accompanied by thrombocytopenia who were admitted to the Emergency Department, Peking University People's Hospital from January 2015 to January 2020 were included as the study subjects and categorized into the severe bleeding group (n=7) and mild/no bleeding group (n=14) based on their bleeding conditions; as well as the multiple-site thrombosis group (n=7) and pulmonary artery thrombosis groups (n=14) based on the presence of thrombosis at sites other than the pulmonary artery; and into the death group (n=5) and survived group (n=16) based on their survival status. Clinical data were collected and compared between groups. Results A total of 21 APE patients with thrombocytopenia were included in this study, involving 7 males and 14 females, with an average age of (63.2±18.9) years. The etiologies included immune thrombocytopenic purpura (5 cases), antiphospholipid syndrome (4 cases), eosinophilia (3 cases), drug-related thrombocytopenia (2 cases), systemic lupus erythematosus (2 cases), cancer-associated thrombocytopenia (2 cases), and 3 cases of unknown etiology. Nineteen patients received anticoagulant therapy. Fibrinogen and fibrinogen/albumin ratios were higher in the pulmonary artery thrombosis group than in the multi-site thrombosis group (P

Background and Objective: Surgical treatment is an effective option for symptomatic benign prostatic hyperplasia (BPH), after failed conservative therapy. Transurethral resection of the prostate (TURP) is considered as a standard treatment method for the management of the small to medium prostate while transvesical open prostatectomy (OP) is a standard option for great prostate. The objective of this study is to evaluate the efficacy and safety of both (B-TURP) and (OP). Methods: The present study included 73 patients underwent either transvesical open prostatectomy (31 patients) or bipolar transurethral resection of the prostate (42 patients) between May 2019 to May 2021, in Erbil-city. The baseline characteristics, intraoperative and postoperative characteristics plus early and late adverse effects were obtained from medical records for all patients in both groups, retrospectively. The data analyzed and compared statistically. Results: The baseline characteristics in the studied groups showed no significant differences except for the prostate size which was more on the OP group. According to the results, operative time was significantly (P

Abstract Background Previous studies on PCT for urinary tract infections (UTI) have focused primarily on minors. This study investigated the predictive value of the neutrophil-to-lymphocyte ratio (NLR), C-reactive protein (CRP) level and procalcitonin (PCT) level in adult patients with bacteriuria in IUC. Methods This case‒control study included 85 patients with bacteriuria (PB) in the ICU from March 2021 to Jan 2024 based on positive urine culture results and a control group (n = 136) from Jan 2024 to March 2024. Patient data were collected using a hospital information management system. ROC curves of the NLR, CRP and PCT were use to predict the PB. Results The AUCs of the NLR, CRP and PCT for the prediction of PB in ICU were 0.711 (95% CI 0.644–0.772), 0.855 (95% CI 0.800–0.900), and 0.884 (95% CI 0.832–0.924), respectively; the optimal thresholds were 8.02, 18.52 mg/L, and 0.215 ng/mL, respectively; the sensitivities were 69.0 (95% CI 56.9–79.5), 90.1 (95% CI 80.7–95.9), and 83.1 (95% CI 72.3–91.0), respectively; and the specificities were 67.6 (95% CI 59.1–75.4), 68.4 (95% CI 59.9–76.1), and 80.9 (95% CI 73.3–87.1), respectively. The negative predictive value (NPV) of CRP is greater than that of PCT. In bacteriuria caused by Candida infections, CRP and PCT have higher sensitivity and NPV. Conclusions Combined CRP and PCT testing is more helpful for diagnosing bacteriuria. CRP and PCT have higher sensitivity and NPV in diagnosing bacteriuria caused by Candida infection.

Abstract The ongoing coronavirus disease 2019 (COVID-19) pandemic presents serious public health threats. Omicron, the current most prevalent strain of COVID-19, has a low fatality rate and very high transmissibility, so the number of patients with mild symptoms of COVID-19 is rapidly increasing. This change of pandemic challenges medical systems worldwide in many aspects, including sharp increases in demands for hospital infrastructure, critical shortages in medical equipment, and medical staff. Predicting deterioration in mild patients could alleviate these problems. A novel scoring system was proposed for predicting the deterioration of patients whose condition may worsen rapidly and those who all still mild or asymptomatic. Retrospective cohorts of 954 and 2,035 patients that quarantined in the Residential Treatment Center were assembled for derivation and external validation of mild COVID-19, respectively. Deterioration was defined as transfer to a local hospital due to worsening condition of the patients during the 2-week isolation period. A total of 15 variables: sex, age, seven pre-existing conditions (diabetes, hypertension, cardiovascular disease, respiratory disease, liver disease, kidney disease, and organ transplant), and five vital signs (systolic blood pressure (SBP), diastolic blood pressure (DBP), heart rate (HR), body temperature, and oxygen saturation (SpO2)) were collected. A scoring system was developed using seven variables (age, pulse rate, SpO2, SBP, DBP, temperature, and hypertension) with significant differences between the transfer and not transfer groups in logistic regression. The proposed system was compared with existing scoring systems that assess the severity of patient conditions. The performance of the proposed scoring system to predict deterioration in patients with mild COVID-19 showed an area under the receiver operating characteristic (AUC) of 0.868. This is a statistically significant improvement compared to the performance of the previous patient condition assessment scoring systems. During external validation, the proposed system showed the best and most robust predictive performance (AUC = 0.768; accuracy = 0.899). In conclusion, we proposed a novel scoring system for predicting patients with mild COVID-19 who will experience deterioration which could predict the deterioration of the patient’s condition early with high predictive performance. Furthermore, because the scoring system does not require special calculations, it can be easily measured to predict the deterioration of a patients’ condition. This system can be used as effective tool for early detection of deterioration in mild COVID-19 patients.

Abstract Background With the continuous improvement of diagnosis and treatment technology for cervical spine-related diseases in children at home and abroad, the demand for exploring the developmental anatomy and function of children's cervical spine of different ages is increasing. So the aim of this study was to investigate the changes of anatomical indicators in neurocentral synchondrosis (NCS) of C2–C7 with age and the developmental characteristics of different vertebrae in children aged 1–6 years old. Method A retrospective collection of 160 cases of normal cervical spine CT images of children aged 1–6 years old in provincial tertiary hospitals, according to the age group of 1-year-old into 6 groups. The original data of continuously scanned cervical spine tomography images were imported into Mimics16.0 software, under the two-dimensional image window, selected the measurement tool under the Measurements toolbar to measure and statistically analyzed the anatomical indicators such as cross diameter, sagittal diameter, height, perimeter and area of NCS in the C2–C7 segment of the cervical spine on the coronal plane and cross-section. Results There was no significant difference in the anatomical indexes of cervical spine NCS in children compared with the left and right sides of the same vertebrae (P > 0.05). The same cervical spine generally had differences between the age groups of 1–4 years old and 5–6 years old (P

Abstract Macular edema is a known side effect of taxane-based anticancer drugs. We retrospectively investigated data from 11 centers between January 2016 and December 2021. Among 14,260 patients, 30 (0.21%) developed macular edema; from these, the number of cases associated with nab-paclitaxel was 16 (0.43%), significantly higher than the number of cases associated with paclitaxel or docetaxel (P

Abstract Mechanical ventilation in myasthenic crisis is not standardized and is at high risk of failure. We investigated liberation from mechanical ventilation during myasthenic crisis using a prolonged spontaneous breathing trials (SBT) and sequential pulmonary function tests (PFT). In this retrospective monocenter study, we included patients admitted for a first episode of myasthenic crisis between January 2001 and January 2018. The primary outcome was the incidence of weaning failure upon first extubation in our cohort of patients with MC. Secondary objectives were to determine risk factors and outcome associated with weaning failure upon first extubation in MC. We also compared the characteristics of patients with prolonged weaning. 126 episodes of MC were analyzed. Patient’s age was 64 [42–76] years with 72/126 (56.5%) being women. The median delay between weaning initiation and first extubation was 6 [3–10] days and the median total length of MV was 14 [10–23] days. 118/126 (93.7%) patients underwent prolonged SBT of 8 h or more prior to first extubation. The overall weaning failure rate was 18/126 (14.3%). Extubation was more often successful when the factor precipitating the myasthenic crisis was identified (86/108 (79.6%) vs. 8/18 (44.4%); p = 0.004), whereas PFT was similar in failure or successes. Most weaning failures upon first extubation attempt (11/18; 61%) were attributed to an insufficient stabilization of myasthenia gravis. Duration of mechanical ventilation, an infectious trigger and maximal inspiratory pressure upon intubation were independent risk factors for prolonged weaning. In myasthenic crisis, a standardized protocol including prolonged SBT and respiratory function tests might improve the success of first extubation without prolonging mechanical ventilation. The results of this single center study warrant further evaluation in interventional trials.

Abstract The Duke Criteria have shaped the way infectious endocarditis (IE) is diagnosed in the last 30 years. This study aims to evaluate their current validity and importance in the diagnostic of IE. A retrospective cohort study was conducted on 163 consecutive patients who presented at the University Hospital in Ulm (Germany) with clinical suspicion of IE between 2009 and 2019. With patients’ medical records we differentiated between definitive endocarditis (DIE), possible endocarditis (PIE) and rejected endocarditis (RIE) and assessed the validity of the Duke Criteria in comparison to the final discharge diagnosis. We then tried to identify new potential parameters as an addition to the current valid Duke Criteria. The validity of the Duke Criteria improves with the length of hospitalization (especially cardiac imaging criterion, RIE 33.3%, PIE 31.6% and DIE 41.9%, p = 0.622 at admission and RIE 53.3%, PIE 68.4%, DIE 92.2%, p

Abstract To evaluate the impact of neoadjuvant chemotherapy on perioperative immune function in breast cancer patients, focusing on CD3+, CD4+, CD8+, and natural killer (NK) cells, as well as the CD4+/CD8+ ratio. We retrospectively reviewed medical records of breast cancer patients who underwent surgery with or without neoadjuvant chemotherapy at our medical center from January 2020 to December 2022. Patients were matched 1:1 based on propensity scores. Immune cell proportions and the CD4+/CD8+ ratio were compared on preoperative day one and postoperative days one and seven. Among matched patients, immune cell proportions and the CD4+/CD8+ ratio did not significantly differ between those who received neoadjuvant chemotherapy and those who did not at any of the three time points. Similar results were observed in chemotherapy-sensitive patients compared to the entire group of patients who did not receive neoadjuvant chemotherapy. However, chemotherapy-insensitive patients had significantly lower proportions of CD4+ and NK cells, as well as a lower CD4+/CD8+ ratio, at all three time points compared to patients who did not receive neoadjuvant chemotherapy. Neoadjuvant chemotherapy may impair immune function in chemotherapy-insensitive patients, but not in those who are sensitive to the treatment.

Abstract Background Impaired hospitalizations for heart failure (HHF) and mortality are associated with tricuspid regurgitation (TR). Objectives The objective of this study was to investigate the benefit of transcatheter tricuspid valve replacement (TTVR) over guideline-directed medical therapy (GDMT) in patients with symptomatic severe TR. Methods Between May 2020 and April 2023, 88 patients with symptomatic severe TR were treated in our center. Of these, 57 patients received GDMT alone, and 31 patients underwent combined TTVR and GDMT. We collected and analyzed baseline data, and follow-up information for both groups. The primary endpoints were all-cause mortality and the combined endpoint (including all-cause mortality and HHF). Results At a median follow-up of 20 (IQR 10–29) months, significant improvements were shown in TR severity, right ventricular function, and dimensions in TTVR group (all P

Abstract Atypical haemolytic uremic syndrome (aHUS) is a rare disorder characterised by complement-mediated thrombotic microangiopathy (TMA). Despite clinical guidelines, the diagnosis and treatment of aHUS in its early stages remains challenging. This study examined the annual trends in aHUS clinical practices in Japan and explored factors influencing early diagnosis and treatment. Using data from the 2011–2020 Diagnosis Procedure Combination database, 3096 cases with the HUS disease code were identified, of which 217 were confirmed as aHUS and treated with eculizumab or plasma exchange. Early initiation, defined as starting eculizumab or plasma exchange within 7 days of admission, was the focus of the study. Our study revealed no significant changes over time in the number of aHUS diagnoses, cases treated with eculizumab, or early initiation cases. Early initiation cases underwent haemodialysis earlier and had ADAMTS13 activity measured earlier, shorter hospital stays, and lower hospitalisation costs than late initiation cases. In conclusion, we found no increase in the number of newly diagnosed aHUS cases or early treatment initiation over time. Early recognition of TMA and differentiation of the causative disease are crucial for identifying potential aHUS cases, which may lead to better patient prognoses.

Abstract Preterm delivery (PTD) is associated with severe adverse maternal and neonatal outcomes and higher medical costs. Therefore, PTD warrants more attention. However, predicting PTD remains a challenge for researchers. This study aimed to investigate potential prenatal predictors of PTD. We retrospectively recruited pregnant women who experienced either PTD or term delivery (TD) and underwent laboratory examinations at 32 weeks of gestation. We compared the test results between the two groups and performed logistic regression analysis and receiver operating characteristic (ROC) curve analysis to identify risk factors and predictive factors for PTD. Our investigation revealed that the PTD cohort exhibited statistically significant elevations in lymphocyte count, mean corpuscular hemoglobin concentration, calcium, uric acid, alkaline phosphatase, triglycerides, and total bile acids. Conversely, the PTD group demonstrated statistically significant reductions in mean corpuscular volume, homocysteine, neutrophil to lymphocyte ratio (NLR), monocyte to lymphocyte ratio (MLR), neutrophils to (white blood cells–neutrophils) ratio (dNLR), and (neutrophils × monocytes) to lymphocyte ratio (SIRI). The ROC curve analysis revealed that calcium had an area under the curve (AUC) of 0.705, with a cut-off value of 2.215. Logistic regression analysis showed that premature rupture of membranes was an independent risk factor for PTD. Our study demonstrated that serum calcium levels, NLR, dNLR, and other laboratory tests conducted at 32 weeks of gestation can serve as predictors for PTD. Furthermore, we identified premature rupture of membranes as a risk factor for PTD.

Abstract Adjacent vertebral fracture (AVF) is a serious complication of percutaneous vertebroplasty (PVP) or kyphoplasty (PKP) for osteoporotic vertebral compression fracture (OVCF). This study aimed to explore the incidence and risk factors of AVF following PVP or PKP in postmenopausal women. The incidence of AVF was determined by spinal radiographic examinations. The potential risk factors of AVF were identified by univariate analysis, followed by multivariate logistic regression analyses to determine the independent risk factors. In total, 674 postmenopausal women who were treated with PVP or PKP from December 2019 to February 2022 were enrolled in the study. Among them, 58 (8.61%) women experienced an AVF following PVP or PKP. After adjusting for confounding factors, BMI (OR [95% CI] 0.863 [0.781–0.952]; p = 0.003), previous history of OVCF (OR [95% CI] 1.931 [1.044–3.571]; p = 0.036), and Hounsfield unit (HU) value (OR [95% CI] 0.979 [0.967–0.990]; p

Abstract Thyroid-associated ophthalmopathy (TAO) is a hallmark autoimmune condition, and the treatment of TAO requires a multidisciplinary approach. Radiation therapy (RT) is a viable treatment option for active TAO, IMRT is a more precise technology in radiation oncology. This study aims to evaluate the efficacy, feasibility, and safety of orbital intensity-modulated radiation therapy (IMRT) in the treatment of TAO. A single-center retrospective analysis was conducted, including patients diagnosed with moderate to severe active TAO at the Department of Radiation Oncology, Peking University Third Hospital, from October 2020 to October 2023, who had poor responses to corticosteroid treatment. These patients subsequently received IMRT treatment, followed by a period of follow-up and retrospective analysis. The study focused on the outcomes of treatment efficacy, safety, and acute toxic reactions induced by radiation therapy. Improvements in clinical activity score (CAS) at 4 and 12 months were considered as primary and secondary study endpoints, respectively, along with the incidence rate of adverse events. The median follow-up period was 12 months. The median follow-up time after radiation therapy was 12 months. There was no statistically significant difference in CAS between before and 4 months after radiation therapy (CAS: 5.53 ± 2.07 vs.4.68 ± 2.62; R squared: 0.21; 95% CI: − 1.01–0.02; P = 0.054). However, there was a significant reduction in CAS 12 months post-treatment compared to pre-treatment (CAS: 5.53 ± 2.07 vs. 3.06 ± 2.38; R squared: 0.66; 95% CI: 3.42 − 1.52; P

Abstract This study aimed to analyse the treatment and outcomes of traumatic hip dislocation (THD) in children. Clinical data of children with THD were collected at our clinical centre from 1 June 2012 to 1 January 2023. Demographic data, injury mechanism, type of dislocation, combined injuries, reduction time, reduction method, and radiographs were analysed. The Merle d’Aubigné–Postel hip score was used to evaluate hip function and complications at the final follow-up. A total of 19 children with THD were enrolled, including 12 male and seven female patients, with an average age of 8.28 ± 0.99 years. Posterior dislocation was the main type of dislocation (89.47%). Fifteen patients (78.95%) had experienced high-energy injuries and traffic accidents were the main causes of injury (47.37%). Closed reduction was performed as soon as possible, and open reduction was performed if necessary. The hip scores of 18 patients (94.74%) were excellent. One patient had osteonecrosis of the femoral head, with a hip function score of 10 (moderate). High-energy injuries, such as traffic accidents, have gradually become the main cause of injury. The prognosis for THD in children is generally good.

Abstract Background The indications, benefits, and outcomes of percutaneous transluminal renal artery intervention (PTRI) remain controversial. The study purpose was to evaluate the long-term outcomes of PTRI in clinical practice. Methods A retrospective review of 217 subjects (254 renal arteries; mean age, 59.8 years) who underwent PTRI based on medical database. Results The most common cause of renal artery stenosis was atherosclerosis in 217 (85.4%), followed by Takayasu arteritis (TA) in 23 (9.1%), fibromuscular dysplasia in five (2.0%) and others in nine (3.5%). Mean follow-up duration was 5.7 ± 3.7 years. The first restenosis rate was 7.5% (n = 19; highest in TA: n = 9, 47.4%) and second restenosis occurred in six arteries (five TAs, one fibromuscular dysplasia). Follow-up blood pressure improved from 142.0/83.5 to 122.8/73.5 mmHg (P

Background: In the sub- Saharan Africa, one in every five children dies before their 5th birthday, mostly from preventable causes. Recent data f rom Nigeria, show infant and under-5 mortality rates of 88 and 143 deaths per 1000 live births respectively. Although significant efforts have been made in the last two decades towards the reduction of childhood mortality, the rate still remains unacceptably high. Objective: The aim of the current study was to evaluate the pattern and causes of paediatric (childhood) mortality at Mile 4 Mission Hospital, Abakaliki. This will help us to know exactly what happens in a small mission hospital with few facilities and limited skilled medical personnel. In addition, this is the very first time this study was undertaken in this hospital Materials and Methods: The records of admissions and deaths of children managed at the Mile 4 Mission Hospital from the 1st January 2009 to 31st December 2009 were retrieved from the Medical Records Department for analysis. Results: Of the 1110 patients admitted within this period, 72 died giving an overall mortality of 6.5%. There were 43 males and 29 females, giving a male: female ratio of 1.5:1. Most of the deaths 58 (80.6%) occurred among children aged younger than 2 years. Malaria was the most common presumed cause of death, followed by gastroenteritis and bronchopneumonia. Twelve and half percent (12.5%) of the children died within 24 hours of admission. The commonest causes of death within 24 hours were severe anaemia, pneumonia and gastroenteritis. The modal months for childhood mortality in this hospital were May and August. Conclusion: Mortality was commonest among children younger than 2 years of age. Malaria, gastroenteritis and pneumonia were the commonest causes of death. A proactive planning taking into account the seasonal variation of these diseases could reduce the childhood mortality in this centre

Abstract With distinct advantages in clinical application, total knee arthroplasty (TKA) is an effective surgical option for treating end-stage osteoarthritis in the knee. After TKA, incisional problems are one of the major factors influencing the speed in which patients recover. Although it is widely acknowledged that preoperative hypoalbuminemia and the incidence of incisional complications are significantly associated, it is still unclear if postoperative hypoalbuminemia raises the risk of incisional complications following TKA. Furthermore, human serum albumin (HSA) is frequently utilized domestically and internationally to treat postoperative hypoalbuminemia; nevertheless, there is ongoing discussion on whether HSA supplementation can enhance postoperative clinical outcomes. To investigate the relationship between hypoalbuminemia and suboptimal incision healing following TKA, as well as to determine whether HSA supplementation can enhance incision healing after surgery, we collected clinical data for this study. The study sample consisted of 22 patients with poorly healed incisions and 120 cases with normal healing of incisions who underwent TKA treatment for knee osteoarthritis (KOA) in the operator's hospital's Department of Orthopaedics between July 1, 2020, and July 1, 2023. To determine the prevalence of postoperative poor incision healing, data on patients' basic characteristics, preoperative test results, surgical data, postoperative test results, and postoperative incision healing were gathered. The contributing factors to inadequate recovery after surgery were examined using SPSS software. After controlling for confounding variables, a multivariate regression analysis model was used to examine the relationship between postoperative hypoalbuminemia, HSA supplementation, and poor incision healing. 22 cases (15.49%) had poor wound healing following surgery. The findings of multivariate regression analysis after controlling for confounders indicated that there was no correlation between poor wound healing and postoperative albumin level (P > 0.05). Similarly, there was no association (P > 0.05) seen between HSA supplementation and poor incision healing. Following the TKA, postoperative hypoalbuminemia does not raise the risk of incisional problems, and postoperative HSA supplementation neither lowers nor enhances the risk of inadequate incisional healing.

Abstract Female urethral caruncle is the most common urethral mass in postmenopausal women, yet there is a lack of studies on its imaging. The aim of this study was to provide a summary of the clinical and ultrasound features as well as the precise location of female urethral caruncle. This study reviewed the clinical and ultrasonographic records of 20 consecutive women with pathologically confirmed urethral caruncle. Data on patient demographics, symptoms, and transperineal and transrectal ultrasound imaging features, including location, shape, margin, size, blood flow, and inner echo of the caruncle, were extracted. Each patient presented with only one mass at the urethral meatus. Most caruncles were located on the posterior lip (75%) of the urethra, presenting as oval (80%), mixed-echoic (50%), or hypo-echoic (40%) nodules with abundant linear (40%) or dendritic (60%) blood flow. The average distance between the bladder neck and the cranial end of the masses was 28 mm. Hyper-echogenic spots, cystic echo areas, and macrocalcifications were detected in thirteen caruncles (70%). This study shows that transperineal combined with transrectal ultrasound can be used to assess female urethral caruncle, and its relative location to the urethra can be accurately described, which is helpful for surgeons making preoperative localization and conversations.
