Background: Plasma cell leukemia (PCL) is a rare monoclonal gammopathy, associated with short survival. Because of its very low incidence, only a few cohorts have been reported and thus, information on this disease is scarce. The goal of this study was to better understand the clinical features, prognostic factors, and efficacy of modern treatments in both primary PCL (pPCL) and secondary PCL (sPCL). Methods: We performed a retrospective, multicenter study of patients diagnosed with PCL, defined as circulating plasma cells ≥20% of total leukocytes and/or ≥2 × 109/L. Results: We identified 99 eligible PCL patients, of whom 33 were pPCL and 66 were sPCL. The median progression‐free survival (PFS) to frontline treatment and overall survival (OS) were, respectively, 4.8 (95% CI, 0.4–9.2) and 18.3 months (95% CI, 0.0–39.0) for pPCL and 0.8 (95% CI, 0.5–1.1) and 1.2 months (95% CI, 0.9–1.5) for sPCL (both p < 0.001). We observed no improvement in OS over time (2005–2012 vs. 2013–2020, p = 0.629 for pPCL and p = 0.329 for sPCL). Finally, our data suggested that sPCL originates from a high‐risk multiple myeloma (MM) population with a short OS (median 30.2 months), early relapse after stem cell transplant (median 11.9 months) and a high proportion of patients with multiple cytogenetic abnormalities (36% with ≥2 abnormalities). Conclusions: This study is one of the largest PCL cohorts reported. We are also the first to investigate characteristics of MM before its transformation into sPCL and demonstrate that high‐risk biologic features already present at the time of MM diagnosis. Moreover, our data highlights the lack of improvement in PCL survival in recent years and the urgent need for better treatment options. [ABSTRACT FROM AUTHOR]

Background/Aims: Anaemia is associated with negative outcomes for both mothers and infants. Better understanding of its consequences could lead to improved guidelines for screening and treatment. The aim of this study was to investigate anaemia in pregnancy and adverse maternal and fetal outcomes among pregnant women in Oman. Methods: This retrospective study examined the medical records of women who gave birth at a university hospital in Oman over a 3-year period. Chi-squared tests were used for data analysis. Results: A total of 723 pregnant women were included, with 62.8% diagnosed with anaemia. Anaemia was significantly associated with preterm birth (P=0.037), low birth weight (P=0.009), intrauterine growth restriction (P=0.002) and postpartum heamorrhage (P=0.019). Conclusions: Anaemia is a significant health concern for pregnant women in Oman. Further research will provide more data on its effects, informing targeted interventions and policy enhancements. Implications for practice: Early antenatal screening, targeted iron supplementation, nutritional education, appropriate treatment and active management during birth would help address this issue.

Background: Non‑intestinal adenocarcinoma of the nasal cavity and paranasal sinuses (non‑ITAC) is a heterogeneous tumour that has rarely been reported in previous studies. We compared and analysed the symptoms, radiographic and pathological features, treatment methods, and prognosis of patients with low-grade (G1) and high-grade (G3) tumours. Methods: This was a retrospective study included 22 patients with pathologically confirmed non-ITAC of the nasal cavity and paranasal sinuses who were treated between January 2008 and December 2021 at a single centre. Of these, 11 patients had G1 tumours, and 11 patients had G3 tumours. Clinicopathological features, treatment methods, and survival outcomes were analysed. Results: The median follow-up period was 48.5 months. Nasal congestion was the most common initial symptom, and the nasal cavity was the most frequently involved site. For G1 tumours, the main treatment was simple surgery, 1 and 3‑year overall survival (OS) rates were 100 and 88.9%, while the 1 and 3‑year local control (LC) rates were 100 and 100%, respectively. For G3 tumours, the main treatments were surgery combined with radiotherapy and/or chemotherapy,1 and 3‑year OS rates were 72.7 and 72.7%, while the 1 and 3‑year LC rates were 100 and 90.91%, respectively. G3 tumours was associated with significantly shorter overall survival than G1 tumours (P = 0.035). Patients with stage III-IV showed shorter overall survival compared to stage I-II patients (P = 0.035). Conclusions: Non-ITAC of the nasal cavity and paranasal sinuses may frequently occur in the nasal cavity. The main treatment modality is surgery, supplemented by radiotherapy and chemotherapy. Pathological grade and tumour stage were poor prognostic factors for the disease. [ABSTRACT FROM AUTHOR]

Objectives: The aim of this retrospective study was to compare the clinical results of two root canal sealers and three obturation techniques used for non-surgical root canal treatment. Materials and methods: A total of two hundred eighty-three root canal treated teeth in two hundred thirty-seven patients with minimum a 6-month follow-up was included for this study. The canals were filled with three different modes: 1) cold lateral condensation (CLC) and AH Plus Sealer; 2) continuous wave condensation technique (CWC) and AH Plus Sealer, and 3) sealer-based obturation technique (SBO) and AH Plus Bioceramic Sealer. The treatment outcome was analysed based on clinical signs and symptoms, and periapical radiograph (periapical index, PAI). Results: There were no significant differences in treatment outcome between various sealers and filling techniques applied. The sealer extrusion was found most frequently in the CWC group (60.67%), followed by SBO (59.21%) and CLC (21.19%) with statistically significant differences (p <.05). The initial diagnosis, previous treatment and sealer extrusion (p <.05) were prognostic factors that affected treatment outcome. Conclusions: Based on the findings of this study, neither the sealer type nor the filling technique affected the treatment success while preoperative diagnosis, previous treatment and sealer extrusion had significant effect on the outcome. Clinical relevance: A bioceramic sealant applied along with the single-cone technique might be considered as an alternative method in root canal obturation. [ABSTRACT FROM AUTHOR]

La mammoplastie de réduction concerne en grande partie des femmes en âge de procréer et peut théoriquement interférer avec les capacités d'allaitement maternel (AM), alors que les bénéfices de l'AM ont bien été démontrés. Les données actuelles de la littérature ne permettent pas de fournir une information précise sur les possibilités d'AM après mammoplastie de réduction. L'objectif de cette étude est d'évaluer la capacité d'AM sur le long terme chez les femmes après mammoplastie de réduction réalisée dans le service de chirurgie plastique de l'hôpital Saint-Louis (AP-HP). Il s'agit d'une étude rétrospective, comparative, concernant des patientes ayant bénéficié d'une mammoplastie de réduction à l'hôpital Saint Louis entre 2010 et 2017 et ayant eu des enfants avant ou après chirurgie. Les données concernant l'intervention ont été recueillies dans le dossier médical, et la capacité à allaiter a été évaluée à l'aide d'un questionnaire standardisé lors d'un entretien téléphonique. L'allaitement des enfants nés avant chirurgie a été comparé à l'allaitement des enfants nés après chirurgie. Nous avons analysé l'AM sur 21 naissances avant chirurgie et 35 naissances après chirurgie. Le taux d'initiation à l'AM était similaire entre les deux groups (83 % vs 90 %, p = 0,7), la durée médiane d'AM était significativement réduite après chirurgie (10 semaines vs 3 semaines, p < 0,01), ainsi que le taux d'enfants allaités à 3 mois (43 % vs 11 %, p < 0,01). Le taux d'utilisation de préparations infantiles était plus élevé après chirurgie (74 % vs 100 %, p < 0,01), ainsi que le taux d'arrêt d'allaitement pour cause d'hypogalactie (11 % vs 69 %, p < 0,001) L'allaitement après mammoplastie de réduction est possible, mais plus difficile à maintenir sur le long terme. Les patientes doivent en être informées avant la chirurgie, et celles qui souhaitent allaiter après la chirurgie doivent y être encouragées à la maternité. Breast reduction surgery often concern women of childbearing age. However, it can interfere with the ability to breastfeed, whereas the benefits of breastfeeding are well known. Current data in the literature do not provide precise information on the possibilities of breastfeeding after breast reduction surgery. The aim of this study was to assess long-term breastfeeding ability of women after breast reduction performed in our centre. This is a retrospective comparative study including patients treated with breast reduction at Saint-Louis Hospital between 2010 and 2017 and who have had children before or after surgery. Operative details were retrieved from medical records and ability to breastfeed was assessed during a phone interview. Breastfeeding before surgery was compared to breastfeeding after surgery. We analysed 21 births before and 35 births after breast reduction. Breastfeeding initiation was similar in the two groups (90% vs. 83%, P = 0.7), but the median duration was significantly shorter after breast reduction compared with before (3 weeks vs. 10 weeks; P < 0.01), the rate of breastfed child at 3 months was lower after surgery (11% vs. 43%; P < 0.01), the use of infant formula was higher after surgery (100% vs. 74%, P < 0.01), and we found a higher rate of discontinuation caused by hypogalactia (69% vs. 11%; P < 0.001). Breastfeeding is possible but more difficult to sustain over time after breast reduction. Patients need to be made aware of that before surgery, and patients who still want to breastfeed should be encouraged at the maternity. [ABSTRACT FROM AUTHOR]

Purpose: We investigated potential risk factors for visual prognosis in Japanese patients with exogenous endophthalmitis. Methods: In this retrospective observational multicenter cohort study, risk factors for legal blindness at 12 weeks after treatment initiation were evaluated based on patient characteristics, initial BCVA, causative events, pathogens, ocular symptoms, duration from symptom onset to initial treatment, and selected treatments. Results: Overall, 23.1% of eyes developed legal blindness. The six risk factors for legal blindness were presence of eye pain, pathogen identification, poor BCVA at the initial visit, longer duration from symptom onset to initial treatment, type of causative event, and type of causative pathogen. Regarding the type of causative pathogen, coagulase-negative staphylococci was associated with a better visual impairment outcome. Conclusion: Exogenous endophthalmitis remains a severe ocular infection; however, it can be managed with rapid treatment, as well as other advances in medical knowledge and technology.

American pikas (Ochotona princeps) are small lagomorphs that live in mountainous talus areas of western North America. Studies on the histopathology of American pikas are limited. We summarize here the clinical histories, and gross and histologic findings of 12 American pikas, including 9 captive (wild-caught) and 3 wild animals. Death was often attributed to stress (transport, handling, anesthesia) with few-to-no premonitory clinical signs. Infection was the cause of death in 2 cases: 1 had bacterial pyogranulomatous dermatitis, cellulitis, and lymphadenitis with sepsis; the other case had oomycete-induced necrotizing colitis. Incidental parasitic infections included sarcocystosis, nematodosis (oxyurids), and ectoparasitism. Most animals with adequate nutritional status had periportal hepatic lipidosis; this finding was absent in all animals with adipose atrophy, and it is possible that periportal hepatic lipidosis is non-pathologic in American pikas. Three cases had myocardial necrosis that was considered the cause of death; the cause of necrosis was not determined, but it may have been caused by stress or vitamin E–selenium deficiency. Esophageal hyperkeratosis was noted in animals with a history of anorexia and negative energy balance; accumulation of esophageal keratin can result from lack of mucosal abrasion by ingesta. Several histologic findings that are likely normal in American pikas include splenic extramedullary hematopoiesis, thymic tissue in adults, and Clostridium sp. in the enteric lumen.

• High red blood cell distribution width (RDW) is independently associated with increased short- and long-term all-cause mortalities in patients with aortic stenosis (AS). • RDW exhibits comparable predictive performance to acute physiology score III and outperforms other critical illness scores in predicting the prognosis of patients with AS. • For AS patients with high RDW, those < 75 years old had higher death risks than those ≥ 75 years old. It is essential to assess the risk stratification of patients with aortic stenosis (AS). To clarify the predictive value of red blood cell distribution width (RDW) in AS patients using a large cohort from the MIMIC-IV database. Restricted cubic spline, the Kaplan-Meier method, and logistic and Cox regression analyses were used to explore the association between RDW and all-cause mortality in AS patients. Multivariate adjustments, propensity score matching and weighting, and subgroup analysis were conducted to exclude confounding factors. Receiver operating characteristic (ROC) and decision curve analysis (DCA) curves were drawn to evaluate the predictive performance of RDW. 1,148 patients with AS were included. Their death risks gradually increased with the elevation of RDW. Multivariate-adjusted 90-day (OR: 2.12; HR: 1.90; p = 0.001) and 1-year (OR: 2.07; HR: 1.97; p < 0.001) all-cause mortalities were significantly higher in patients with RDW≥14.7 %, which remained robust after propensity score matching and subgroup analysis. For AS patients with high RDW, those < 75 years old had higher death risks than those ≥ 75 years old. The area under the ROC curve of RDW were 0.741 and 0.75 at 90-day and 1-year follow-ups, respectively, exhibiting comparable performance to acute physiology score III and outperforming other critical illness scores in predicting the prognosis of AS patients. DCA curves also illustrated that RDW had a wide range of net benefits. High RDW was independently associated with increased 90-day and 1-year all-cause mortalities of AS patients, with strong predictive capability of prognosis. [ABSTRACT FROM AUTHOR]

Retrograde open mesenteric stenting (ROMS) is an alternative to mesenteric bypass in patients with acute mesenteric ischemia (AMI) with variable reported 30-day mortality rates. Large studies evaluating patient outcomes following ROMS are scarce. Our study aims to assess the results of this approach among patients presenting with AMI. We reviewed all the patients with AMI who were treated with ROMS (2011-2022). Patient demographics, presentation, operative details, and outcomes were analyzed. Primary end points were in-hospital, 30-day, and 1-year mortality. Kaplan-Meier estimate for 1-year mortality and primary patency loss were generated. Secondary end points included postoperative 30-day complications. Between 2011 and 2022, ROMS was attempted on a total of 42 patients. The median age was 70 ± 15 years and the majority of patients were female. Pain out of proportion to the physical examination was the most common presenting symptom (n = 18, 42.9%) followed by peritonitis (n = 14, 33.4%). All patients underwent preoperative intravenous contrast computed tomography imaging. In situ thrombosis was identified as the etiology of AMI in 36 patients (85.7%). Technical success was achieved in 40 patients (95.2%). Conventional, non-hybrid operating rooms were used for the majority of cases. Revascularization of all 40 patients involved angioplasty and stenting of superior mesenteric artery. A single stent was placed in 35 patients (87.5%) and the reminder had more than one stent. Eighty percent of patients required bowel resection. A second-look laparotomy was required in 34 patients (85.0%). The mean operative time, including both the general surgery and vascular surgery portions of the index procedure, was 192 ± 57 minutes. Sepsis was the most common complication observed within 30 days, occurring in 8 patients (20.0%). In terms of mortality, 13 patients (32.5%) died during their index hospitalization, and 9 died (22.5%) within 30 days. On Kaplan-Meier analysis, the 1-year overall patient survival rate was 58.6%, and the primary patency rate for stents was 51.4%. ROMS has an excellent technical success rate in management of AMI with lower than traditionally reported mortality rates for AMI. The dual benefits of rapid revascularization and bowel evaluation should make this surgical modality an alternative approach for treatment of AMI. [ABSTRACT FROM AUTHOR]

Background: Although chemoradiotherapy is an effective treatment for esophageal cancer, its feasibility in esophageal cancer with cirrhosis remains largely unclear. Methods: We retrospectively studied 11 patients with superficial esophageal cancer with liver cirrhosis (Child-Pugh score ≤8) who underwent radical chemoradiotherapy from four centers, and the overall survival rate, local control rate and adverse events at 1 and 3 years were explored. Results: The median age of the included patients was 67 years (Inter-Quartile Range 60–75 years). Complete response was observed in most patients (n = 10, 90.9%), and the remaining patient was unevaluable. The 1- and 3-year overall survival and local control rates were 90.9% and 90.9%, and 72.7% and 63.6%, respectively. Hematotoxicity was a common adverse reaction, and seven patients developed radiation esophagitis, with grade 3–4 observed in two cases. All cases of radiation dermatitis (n = 4) and radiation pneumonia (n = 2) were grade 1–2. Gastrointestinal bleeding occurred in two patients, including one with grade 1–2 bleeding, and one died. Conclusion: Radical chemoradiotherapy is a potential treatment option for patients with superficial esophageal cancer complicated with cirrhosis. However, it can increase the risk of bleeding, which warrants prompt recognition and intervention. [ABSTRACT FROM AUTHOR]

Purpose: To determine the effect of aspirin on hepatocellular carcinoma (HCC) recurrence and survival after thermal ablation. Methods: A retrospective analysis was performed to evaluate the efficacy and safety of aspirin in combination with thermal ablation. The clinical data were collected for the enrolled patients. Progression-free survival (PFS), overall survival (OS), and adverse events were analyzed. Results: A total of 174 patients with HCC were enrolled. The median PFS was 11.1 (95% confidence interval [CI]: 8.1− 14.0) months for patients who took aspirin and 8.6 (95% CI: 5.5− 11.8) months for patients who did not take aspirin. The median OS of patients in the aspirin group was 76.7 (95% CI: 58.1− 95.3) months and that in the non-aspirin group was 53.5 (95% CI: 42.7− 64.3) months. In patients with non-viral HCC, OS was significantly better for the aspirin group (P = 0.03) after ablation. The PFS of patients who underwent ablation alone in the aspirin group was obviously superior to that of patients in the non-aspirin group (P = 0.002). Stratified Cox regression analysis demonstrated that aspirin use after ablation might be a protective factor in specific HCC patient subgroups. The incidence of major adverse events did not significantly differ between the two groups. Conclusion: Low-dose aspirin use was associated with better OS in patients with non-viral HCC after thermal ablation. In patients who received thermal ablation alone, the administration of low-dose aspirin could improve PFS. Aspirin use might be a protective factor in some patients after ablation.

Background: Vasovagal syncope (VVS) is the most common type of orthostatic intolerance in children. We investigated whether platelet-related factors related to treatment efficacy in children suffering from VVS treated with metoprolol. Methods: Metoprolol-treated VVS patients were recruited. The median duration of therapy was three months. Patients were followed and divided into two groups, treament-effective group and treatment-ineffective group. Logistic and least absolute shrinkage selection operator regressions were used to examine treatment outcome variables. Receiver-operating characteristic (ROC) curves, precision–recall (PR) curves, calibration plots, and decision curve analyses were used to evaluate the nomogram model. Results: Among the 72 patients who complete the follow-up, treatment-effective group and treatment-ineffective group included 42 (58.3%) and 30 (41.7%) cases, respectively. The patients in the treatment-effective group exhibited higher mean platelet volume (MPV) [(11.0 ± 1.0) fl vs. (9.8 ± 1.0) fl, P < 0.01] and platelet distribution width [12.7% (12.3%, 14.3%) vs. 11.3% (10.2%, 12.2%), P < 0.01] than those in the treatment-ineffective group. The sex ratio was significantly different (P = 0.046). A fit model comprising age [odds ratio (OR) = 0.766, 95% confidence interval (CI) = 0.594–0.987] and MPV (OR = 5.613, 95% CI = 2.297–13.711) might predict therapeutic efficacy. The area under the curve of the ROC and PR curves was computed to be 0.85 and 0.9, respectively. The P value of the Hosmer–Lemeshow test was 0.27. The decision curve analysis confirmed that managing children with VVS based on the predictive model led to a net advantage ranging from 0.01 to 0.58. The nomogram is convenient for clinical applications. Conclusion: A novel nomogram based on age and MPV can predict the therapeutic benefits of metoprolol in children with VVS.

Objectives: To examine the distribution, clinical characteristics, and management of priapism in a Saudi Arabian tertiary care setting to provide a regional perspective. Subjects and Methods: This retrospective chart review included 29 male patients presenting with priapism at a tertiary care hospital in Riyadh, Saudi Arabia, from January 2011 to June 2023. Data were collected on patient demographics, clinical presentation, treatment modalities, and outcomes. Results: The study found recurrent episodes of priapism in many patients, with a significant number associated with hematological diseases, notably sickle cell disease. Most treatments involved non-surgical methods. A notable finding was the correlation between the duration of priapism episodes and the likelihood of hospital admissions, suggesting that prolonged episodes often required more extensive medical attention. Conclusions: Priapism often presents as a chronic and recurrent condition requiring personalized management strategies. This study emphasizes the importance of recognizing regional occurrence patterns to enhance the management of priapism and suggests a need for further research in regions where this condition is less common.

Background: Undesirable injuries during the intraoperative period, such as pressure injuries caused by improper positioning, medical devices, or adhesive tapes, can lead to patient harm and decreased satisfaction. This study aims to identify the risk factors of pressure injuries during the intraoperative period and the characteristics of these injuries. Methods: A retrospective case-control study was conducted at King Khaled University Hospital in Riyadh, Saudi Arabia. Data were collected from the hospital incident reporting system and electronic medical records for incidents reported from January 1, 2022 to December 31, 2022. Inclusion criteria consisted of all patients with a reported pressure injury, including pressure ulcers, medical adhesive-related skin injuries, or medical device-related pressure injuries, occurring at least once during surgery. Results: Among the 113 patients, 57 (50.44%) had intraoperative pressure injuries (cases), while 56 (49.56%) did not (controls). The most common locations for pressure injuries were the lips (33.33%). Most of these injuries were classified as Medical Adhesive-Related Skin Injury (61.40%). Stage 1 injuries were observed in 47 cases (82.46%), while Stage 2 injuries were observed in 10 cases (17.54%). Duration of surgery and device tightness were identified as significant risk factors (P < 0.001). Conclusion: This case-control study identified the duration of surgery and device tightness as significant risk factors for intraoperative pressure injuries. The findings emphasize the importance of implementing evidence-based prevention strategies. Healthcare professionals should prioritize staff education and training, while future research should focus on conducting prospective, multicenter studies and developing risk assessment tools and innovative medical devices.

This study aims to analyze the ocular manifestations of syphilis in patients treated at a Portuguese tertiary center over a 14-year period.Patients and Methods: A retrospective review of patients diagnosed with syphilis who presented with ocular symptoms from 2010 to 2023 was conducted. Data collected included demographic information, clinical presentation, ophthalmologic findings, serologic test results, treatment regimens and outcomes.Results: A total of 47 patients with ocular syphilis were identified. The mean age of the cohort was 45, with a male predominance of 78.7%. The most common ocular manifestations included uveitis (mostly posterior and panuveitis), optic neuritis, acute syphilitic posterior placoid chorioretinitis and vitritis. Best corrected visual acuity (BCVA) at presentation was highly variable, ranging from hand movements to no impairment of visual acuity. At the end of the follow-up period, the majority of the study eyes achieved a BCVA between 0 and 0.1 (p< 0,000). Acute syphilitic posterior placoid chorioretinitis was associated with poorer visual outcomes after treatment, indicating its presence is a poor prognosis factor. HIV status, the presence of vitritis, vasculitis and papillitis at presentation, a positive syphilis serology in cerebrospinal fluid and treatment regimen did not appear to have a significant impact on the final BCVA.Conclusion: Ocular syphilis, though rare, remains a significant cause of visual morbidity. Early recognition and prompt treatment are crucial for preventing permanent vision loss. Regular screening and increased awareness among clinicians are essential to manage this potentially sight-threatening condition effectively. Further research is needed to optimize treatment protocols and improve patient outcomes.Keywords: syphilis, uveitis, optic neuritis, retinal vasculitis, retrospective study, penicillin

Abstract Background The incidence of musculoskeletal diseases is increasing in clinical practice, leading to a growing demand for rehabilitation medicine. However, education in musculoskeletal education is lacking in the training of physical medicine and rehabilitation students. This study aims to evaluate the impact of musculoskeletal education on medical students’ learning of rehabilitation medicine and analyze the correlation between influencing factors and education. Objectives The primary objective of this study is to evaluate the impact of musculoskeletal education on medical students’ learning of rehabilitation medicine. Furthermore, the authors aim to analyze the correlation between various influencing factors and the effectiveness of this education, with the goal of informing future educational interventions and enhancing student outcomes. Methods A comprehensive search was conducted across the Pubmed, Ovid, and Cochrane Central Register of Controlled Trials (CENTRAL) databases for relevant articles published from January 2012 to September 2024. The search focused on medical students as the research subjects and musculoskeletal education as the intervention method. Both randomized controlled trials (RCTs) and non-randomized controlled trials (non-RCTs) were included. The selected studies underwent a systematic review, and meta-analysis was performed using R 3.4.4 software. Results After a thorough search, 41 studies were included. The retrospective study indicated that the most common impacts were knowledge acquisition, self-confidence, and satisfaction. The subsequent meta-analysis revealed significant increases in students’ knowledge acquisition [standardized mean differences (SMD) = 2.15, 95% confidence interval [CI] (1.36, 2.94), I 2 = 97%, random effect model] and self-confidence [SMD = 5.81, 95% CI (2.88, 8.75), I 2 = 97%, random effect model]. Compared with the general teaching control group, the knowledge acquisition of students in the observation group improved [SMD = 0.25, 95% CI (0.00, 0.51), I 2 = 83%, in the random effect model]; However, no significant difference in satisfaction occurred [SMD = 0.27, 95% CI (-0.47, 1.01), P > 0.05, I 2 = 89%, in the random effects model]. Conclusion Musculoskeletal education primarily impacts knowledge acquisition self-confidence, and satisfaction among physical medicine and rehabilitation students. The meta-analysis further establishes that musculoskeletal education significantly enhances knowledge acquisition and confidence in these students.

Abstract Background Invasive pulmonary aspergillosis (IPA) is a serious fungal infection. However, current diagnostic methods have limitations. The purpose of this study was to use artificial intelligence to achieve a more accurate diagnosis of IPA. Methods Totally 263 patients (148 cases of IPA, 115 cases of non-IPA) were retrospectively enrolled from a single institution and randomly divided into training and test sets at a ratio of 7:3. Clinic-radiological independent risk factors for IPA were screened using univariate analysis and multivariate logistic regression analysis, after which a clinic-radiological model was constructed. The optimal radiomics features were extracted and screened based on CT images to construct the radiomics label score (Rad-score) and radiomics model. The optimal DL features were extracted and screened using four pre-trained convolutional neural networks, respectively, followed by the construction of the DL label score (DL-score) and DL model. Then, the radiomics-DL model was constructed. Finally, the combined model was constructed based on clinic-radiological independent risk factors, the Rad-score, and the DL-score. LR was adopted as the classifier. Receiver operating characteristic (ROC) curves were drawn, and the areas under the curve (AUC) were calculated to evaluate the efficacy of each model in predicting IPA. Additionally, based on the best-performing model on the LR classifier, four other machine learning (ML) classifiers were constructed to evaluate the predictive value for IPA. Results The AUC of the clinic-radiological model for predicting IPA in the training and test sets was 0.845 and 0.765, respectively. The AUC of the radiomics-DL and combined models in the training set was 0.871 and 0.932, while in the test set was 0.851 and 0.881, respectively. The combined model showed better predictive performance than all other models. DCA showed that taking 0.00–1.00 as the threshold, the clinical benefit of the combined model was higher than that of all other models. Then, the combined model was trained on four other machine learning classifiers, all of which achieved AUC values above 0.80 in the test set, showing good performance in predicting IPA. Conclusion Clinic, CT radiomics, and DL combined model could be used to predict IPA effectively.

Background: No data exist on the efficacy and safety of anlotinib plus camrelizumab doublet as second-line therapy for advanced esophageal squamous cell carcinoma (ESCC). Although anlotinib and the programmed death-1 (PD-1) inhibitor camrelizumab are used as treatments for ESCC, the combined use of anlotinib and camrelizumab as a second-line therapy has not been reported. Therefore, this study explored the efficacy and toxicity of anlotinib plus camrelizumab as second-line therapy for advanced ESCC. Methods: Fifty-eight patients with advanced ESCC undergoing second-line therapy, either with anlotinib plus camrelizumab or anlotinib plus S-1, were enrolled and retrospectively analyzed at Jiangsu Province Hospital of Chinese Medicine from January 2020 to December 2021. The primary endpoint was progression-free survival (PFS), with secondary endpoints including the objective response rate (ORR), disease control rate (DCR), and assessment of toxicity. Results: In patients with advanced ESCC, the anlotinib plus camrelizumab group (N = 32) exhibited longer PFS (8.00 vs. 4.53 months, P

Background/purpose: 2016 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) primary Sjögren's syndrome (SS) diagnostic criteria did not incorporate radiographic examination while staging SS according to salivary gland imaging and serological autoantibody tests was not discussed. The aim is to study the value of parotid sialography for diagnosing SS, and to initially explore the method of staging SS based on the results of imaging and serological autoantibody tests. Materials and methods: 287 patients’ clinical records were included. The sensitivity and specificity of parotid sialography in the diagnosis of SS were investigated. SS patients were categorized into early stage (autoantibody positive, imaging does not support SS), active stage (autoantibody positive, imaging supports SS), and quiescent stage (autoantibody negative, imaging supports SS), clinical characteristics of different stages were compared. Results: The sensitivity of parotid sialography for the diagnosis of SS was 82.6%, the specificity was 71.5%. 10-minute USFR of the patients in the active stage (0.18 ± 0.38 ml/10min) was significantly lower than that of early stage (0.34 ± 0.47 ml/10min) and quiescent stage (0.54 ± 0.52 ml/10min), P = 0.010, and the rate of confirmed SS was significantly higher in the active stage (82.9%) than that in the early stage (44.4%) and the quiescent stages (14.8%), P

AIM: Urolithiasis is the most prevalent urinary tract disease, posing a global public health concern. The escalating prevalence and recurrence rates of urolithiasis are attributed to lifestyle modifications, such as reduced physical activity and dietary habits. This retrospective study aims to explore the risk factors associated with urolithiasis among individuals diagnosed with this condition. Method: A retrospective hospital-based study involving 60 participants meeting the inclusion criteria was conducted. The participants were selected through convenience sampling from the urology, nephrology, and medical wards at Saveetha Medical College and Hospital. Demographic variables were collected, and the risk factors were assessed using a checklist on one-to-one interviews. Results: The study unveiled that most participants (68%) were male. Eighty percent of participants had the risk factor of decreased water intake, 74% consumed excess tomatoes, 56% had a history of recurrent urinary tract infections, 64% consumed an excessive amount of salt daily, 72% experienced a decreased urine output, 53% had a habit of alcohol consumption, and 45% included milk and milk products in their daily diet. A small percentage (5%) had a family history of urolithiasis. Additionally, 6% were undergoing Siddha treatment. Conclusion: The findings from this study underscore the significant factors contributing to urolithiasis. They can inform public health campaigns to raise awareness about lifestyle modifications, dietary changes, and hydration protocols contributing to kidney stone formation.

Abstract This study aims to objectively assess the effect of three surgical approaches for posterior uterine fibroid resection: transumbilical laparoendoscopic single-site surgery (LESS), vaginal natural orifice transluminal endoscopic surgery (vNOTES) in prone position (vNOTES-P), and vNOTES in the lithotomy position (vNOTES-L). A retrospective analysis was conducted on data pertaining to all patients who underwent vNOTES and LESS for single posterior fibroids at our institution from January 2023 to July 2023. Patients were categorized into three groups based on the surgical approach: vNOTES-P group (n = 30), vNOTES-L group (n = 17), and LESS group (n = 32). Comparative analysis was performed on the demographic characteristics and perioperative outcomes among the three groups of patients. All 79 patients underwent surgery without the need for conversion to laparotomy. There were no statistically significant differences among the LESS group, vNOTES-P group, and vNOTES-L group in terms of operative time, intraoperative blood loss, and perioperative complication rates. In the vNOTES-L group, two patients required conversion to LESS during surgery. Patients had faster return of bowel function (less time to flatus) in the vNOTES group compared to the LESS group (P

Most gastrointestinal polyps are asymptomatic; therefore, assessing symptoms associated with cancer and precancerous polyps is essential.

Background: As a chronic inflammatory process, chronic osteomyelitis is caused by bacterial infections that lead to bone destruction. This disease is more common in patients with open fractures and those undergoing multiple surgical procedures after trauma. We aimed to provide a comprehensive overview and critical assessment of the therapeutic efficacy of the anterolateral thigh (ALT) perforator flap in the management of chronic osteomyelitis with dermatologic and soft tissue imperfections localized in the lower extremity. Methods: A retrospective analysis involving a cohort of 16 patients who underwent ALT perforator flap reconstruction for the management of chronic osteomyelitis in the calf region that manifested with integumentary deficiencies was conducted. Results: During the follow-up period spanning from 4 months to 2 years, all 16 patients who underwent ALT perforator flap transplantation exhibited flap viability. Among these cases, 15 patients made a full recovery from the infection and 1 patient had partial survival. Among the 15 cases, 2 patients developed vascular crisis (owing to venous thrombosis during surgical exploration). One patient had a relapse of the disease 1-year post-surgery. The success rate of this surgical method was 15/16, and the surgical complications included flap crisis, flap necrosis, delayed wound healing, and recurrence of infection. Conclusion: The ALT perforator flap, which can cover bone and soft tissues and effectively control infections, can be applied to the treatment of chronic osteomyelitis of the lower limbs with skin defects. Overall, the muscle flap fills the dead space and medullary cavity and skin flap covers the skin defect.

Purpose: This study aimed to evaluate the effectiveness of a novel technique for securing the tibial component in cementless total knee arthroplasty (TKA) by utilizing resected cancellous bone to fill the peg holes. It was hypothesized that this method would reduce the incidence of radiolucent lines (RLLs) on plain radiographs. To test this hypothesis, a retrospective comparison of plain radiographs from patients who underwent the bone-filling technique (bone filling group) versus those who did not receive this treatment (conventional group) was conducted. Methods: Participants were 151 patients (213 joints) who underwent TKA with the NexGen trabecular metal (TM) modular tibia (Zimmer Biomet) from 2011 to 2016 [bone filling group, 54 patients (69 joints); conventional group, 100 patients (144 joints); 3 patients had 1 joint in each group]. Clinical evaluations, plain radiographs, and operative time were compared between groups. Results: The mean follow-up period was 5 years and 5 months. Knee Society Scores and Knee Society Functional Scores did not differ significantly between groups; however, the bone filling group had a significantly lower incidence of RLLs (p ​

Purpose: To retrospectively evaluate the clinical outcomes of immediately loaded zygomatic implants combined with anterior regular implants (hybrid zygoma) for the fixed rehabilitation of atrophic maxillae. Materials and Methods: A total of 18 patients were enrolled in this study and treated with the hybrid zygoma concept by an experienced surgeon. Followup visits were planned after 1 week, 3 weeks, 4 months, 6 months, then annually. At the last follow-up appointment (mean: 36 months after surgery; range: 24 to 52 months), the prostheses were unscrewed and the implants and periimplant tissues were examined. The primary outcome evaluated was implant success. Following the criteria proposed by Aparicio et al, implant success was classified in five grades, with grade I representing the best condition and grade V representing a failure. At the annual check-up, patients were asked to fill out a questionnaire to evaluate their satisfaction with their oral rehabilitation. Results: A total of 80 implants (34 zygomatic and 46 regular) were inserted. One zygomatic implant was lost in one patient, and two regular implants failed in two other patients. Of the zygomatic implants, 24 (70.6%) presented a success grade I, 9 (26.5%) a success grade II, and 1 (2.9%) a grade V. Sinusitis was the most common biologic complication, occurring in two patients (5.6%). Two patients showed unilateral upper lip paresthesia that was persistent at the last follow-up appointment. According to the annual follow-up visit questionnaire data, 72%, 89%, and 94% of patients declared that they were satisfied with their phonetic ability, chewing ability, and esthetics, respectively. Conclusion: Although zygomatic implants combined with anterior regular implants present a higher risk of complications than traditional implantology, they allow for immediately loaded full-arch fixed rehabilitation of patients with advanced atrophy of the posterior maxilla, which provides satisfactory chewing ability, esthetics, and phonetics.

Abstract We aimed to assess long-term disease progression in patients with severe keratoconus (KC). Clinical records of 125 patients (201 eyes) with severe KC followed-up for > 12 months were retrospectively analyzed. From these, 28 patients (31 eyes) were included. Corneal topography parameters evaluated included thinnest corneal thickness (TCT), maximum keratometry (Kmax), anterior and posterior mean corneal radii of 3 mm (aKM, pKM), steep keratometry, and KC screening indices. All patients wore rigid gas permeable contact lenses (RGPCLs) for an extended period. The median patient age and follow-up period were 20 (interquartile range [IQR] 17–22) years and 25 (15–38) months, respectively. Compared to baseline, the aKM, Kmax, and KC screening indices on the anterior corneal surface were reduced at the final follow-up (P

Abstract Objective Serum lipoprotein(a) [Lp(a)] is a risk factor of cardiovascular diseases. However, the relationship between the serum Lp(a) and clinical outcomes has been seldom studied in Chinese hospitalized patients with cardiovascular diseases. Methods We retrospectively collected the clinical data of hospitalized patients with cardiovascular diseases in the Cardiovascular Department of Dongguan People’s Hospital from 2016 to 2021 through the electronic case system. Patients were divided into 4 groups based on Lp(a) quartiles: Quartile1 (≤ 80.00 mg/L), Quartile 2 (80.01 ~ 160.90 mg/L), Quartile 3 (160.91 ~ 336.41 mg/L), Quartile 4 (> 336.41 mg/L). Cox proportional hazard regression models were constructed to examine the relationship between Lp(a) and cardiovascular events. Results A total of 8382 patients were included in this study. After an average follow-up of 619 (320 to 1061) days, 1361 (16.2%) patients developed major adverse cardiovascular events, and 125 (1.5%) all-cause death were collected. The incidence of MACEs was 7.65, 8.24, 9.73 and 10.75 per 100 person-years in each Lp(a) quartile, respectively; the all-cause mortality was 0.48, 0.69, 0.64 and 1.18 per 100 person-years in each Lp(a) quartile, respectively. The multivariate Cox regression analysis suggested that high Lp(a) level was an independent risk factor for MACEs (HR: 1.189, [95% CI: 1.045 to 1.353], P = 0.030) and all-cause death (HR: 1.573, [95% CI: 1.009 to 2.452], P = 0.046). Conclusion In addition to traditional lipid indicators, higher Lp(a) exhibited higher risks of adverse cardiovascular events and death, indicated worse prognosis. Lp(a) may be a new target for the prevention of atherosclerotic diseases.

Abstract Background Studies on oral health status of adults are sparse and rarely include data on endodontic treatment and trauma. In the military, those data are available because recruits are routinely assessed with a clinical and radiological examination at the start of their career. This study aimed to identify differences in oral health status of Dutch Armed Forces recruits between cohorts, departments, sex, age and rank, with DMF-T, endodontic treatment and dental trauma as outcome measures. Methods Data from Electronic Patient Files from all recruits enlisted in 2000, 2010 and 2020 were used for analysis in a hurdle model resulting in the estimated cohort effect, controlled for the demographic variables. The total number of recruits was 5,764. Due to the retrospective character of the study a proxy was used to compose D-T and dental trauma. Results The mean DMF-T number in recruits decreases from 5.3 in cohort 2000 to 4.13 in cohort 2010 and 3.41 in cohort 2020. The percentage of endodontically treated teeth increases from 6% in cohort 2000 to respectively 9% in 2010 and 8% in 2020. The percentage of recruits showing signs of dental trauma did not change significantly between cohort 2000 (3.1%) and cohort 2010 and 2020 (both 2.7%). Conclusions Oral health in Armed Forces recruits is improving over the years, following a similar trend as the general population in the Netherlands. Lower SES represented by enlisted rank showed substantial lower oral health status.

Background/purpose: Endoscopic stenting at malignant distal duodenum stenosis (MDDS) is challenging because of the duodenal C-loop configuration, the acute angle of the duodenojejunal junction, and the limited length of the endoscope. Few studies have investigated the clinical outcomes of stenting at the distal duodenum. Therefore, this study aimed to investigate the clinical outcomes of treating MDDS with different types of metallic stents. Methods: From January 2012 to December 2020, fifty-six patients with MDDS who underwent duodenal stenting were enrolled for analysis. Thirty-five patients received uncovered self-expandable metallic stents (UC-SEMS), and twenty-one patients received partially covered self-expandable metallic stents (PC-SEMS). All patients were followed up till death or for 18 months. The clinical success rate, stent dysfunction rate, and stent patency were compared between the groups. Multivariate analysis was conducted to identify factors related to stent dysfunction. Results: The clinical success rates were 85.7 % in both the UC-SEMS and PC-SEMS groups. Stent dysfunction rates (UC-SEMS: 34.3 %, PC-SEMS: 38.1 %, p = 0.773) and the average stent patency (UC-SEMS: 117.2 days, PC-SEMS: 100.0 days, p = 0.576) were not statistically different between the groups. Multivariate analysis disclosed the age ≥65 years was significantly related to stent dysfunction (odds ratio: 4.78, p = 0.031). Conclusion: Both UC-SEMS and PC-SEMS are safe and effective treatment options for MDDS. However, stent dysfunction remains a significant issue to overcome, particularly in the elderly. Further research is needed to explore novel strategies that can improve the effectiveness of stent placement and reduce the risk of stent dysfunction.

Background: Injury related death is a leading cause of death globally. Abdominal injuries may occur in up to one third of patients with trauma. Road traffic accidents have become the commonest mechanism of trauma. Materials and Methods: This was a hospital based retrospective descriptive study conducted at Dhulikhel Hospital-Kathmandu University Hospital. Patients admitted with abdominal trauma from July 2021 to December 2023 were included in this study. Results: This study included 60 patients with abdominal trauma. Mean age of patients was 35.60 ± 15.81 (10-76) years. Majority of patients belonged to age group 21-40 years (n=32, 53.3%) with male predominance (Male:female ratio=3.6:1). Blunt abdominal trauma (n=58, 96.7%) was more common than penetrating abdominal trauma (n=2, 3.3%). Road traffic accident (n=31, 51.7%), fall from height (n=22, 36.7%) and physical assaults (n=7, 11.7%) were the mechanisms of injury. In our study, commonly injured organs were spleen(n=19, 30.64%), liver(n=15, 24.19%) and small bowel(n=14, 22.58%). Among the patients with penetrating abdominal trauma, one patient had rectal injury and next patient had stab injury with protruding omentum through the wound. Thirty four patients (56.7%) were managed conservatively and 26 patients (43.3%) underwent operative management. The mortality rate was 8.33% (n=5) of which 4 (80%) had undergone operative management and 1 (20%) was being managed conservatively. Conclusion: Majority of patients with solid organ injury can be managed conservatively while hollow viscus injury undergoes operative treatment. Physically active male population is the most affected group. Road traffic accidents are the leading cause of abdominal trauma followed by fall from height and physical assaults.

Abstract Background Paediatric solid tumours, both benign and malignant, present significant health challenges, particularly in Sub-Saharan Africa where comprehensive data is limited. This study aims to elucidate the prevalence, distribution, and treatment outcomes of paediatric solid neoplasms in a tertiary hospital in South-East Nigeria over a seven-year period. Methods A retrospective cohort study was conducted at Nnamdi Azikiwe University Teaching Hospital (NAUTH), Nnewi, Nigeria. Clinical details and histological slides of confirmed cases from January 2016 to December 2022 were reviewed. Data extraction focused on socio-demographic variables and treatment outcomes, analysed using statistical methods. Results The study included 293 children diagnosed with solid tumours (58.1% malignant, 41.9% benign), with a female predominance (61.8%). The median age at diagnosis was 12 years. Fibroadenoma was the most common benign tumour (61.8% of benign cases), while non-Hodgkin lymphoma was the predominant malignant tumour (18.2% of malignant cases). Treatment abandonment rates differed significantly between benign (13.8%) and malignant (51.2%) tumours. Significant associations were found between treatment outcomes and factors such as gender (p = 0.0001 for benign tumours), age category (p = 0.0001 for benign tumours), and specific diagnoses (p = 0.0001 for both benign and malignant tumours). Conclusion This study underscores the substantial burden of paediatric solid tumours in South-East Nigeria and highlights the critical need for improved treatment adherence strategies, particularly for malignant cases. The findings emphasize the importance of tailored interventions based on tumour type, age, and gender. These insights can inform future research, policy formulation, and healthcare strategies aimed at enhancing the management and outcomes of paediatric solid neoplasms in resource-limited settings.

Abstract Background The influence of home obesogenic environments, as assessed by the validated Family Nutrition and Physical Activity (FNPA) tool, and child obesity during the COVID pandemic were evaluated using electronic health records in this retrospective cohort study. Methods Historical data on BMI and the FNPA screening tool were obtained from annual well-child visits within the Geisinger Health System. The study examined youth ages 2–17 that had a BMI record and an FNPA assessment prior to the pandemic (BMI 3/1/19–2/29/20), 1 BMI record 3 months into the pandemic (6/1/20–12/31/20) and 1 BMI in the second year of the pandemic (1/1/21–12/31/21). Tertiles of obesity risk by FNPA score were examined. Mixed-effects linear regression was used to examine change in BMI slope (kg/m2 per month) pre-pandemic to pandemic using FNPA summary and subscales scores as predictors and adjusting for confounding factors. Results The analyses included 6,746 children (males: 51.7%, non-Hispanic white: 86.6%, overweight:14.8%, obesity:10.3%, severe obesity: 3.9%; mean(SD) age: 5.7(2.8) years). The rate of BMI change in BMI was greatest from early pandemic compared to pre-pandemic for children in lowest versus highest tertiles of FNPA summary score (0.079 vs. 0.044 kg/m2), FNPA-Eating (0.068 vs. 0.049 kg/m2), and FNPA-Activity (0.078 vs. 0.052 kg/m2). FNPA summary score was significantly associated with change in BMI from the pre-pandemic to early pandemic period (p = 0.014), but not associated with change in BMI during the later pandemic period. Conclusions This study provides additional insight into the changes in the rate of BMI change observed among children and adolescents in the United States during the COVID-19 pandemic. The FNPA provides ample opportunity to continue our exploration of the negative impact of the COVID-19 pandemic on the longitudinal growth patterns among children and adolescents.

Abstract Background Spinal intradural tumors are rare and heterogeneous in histological type, aggressiveness, and symptomatology, and there is a lack of data about them. This study investigated the epidemiological features of spinal intradural tumors. Methods This retrospective analysis included patients with spinal intradural tumors who underwent surgical treatment at the Myelopathy and Spondylosis Ward Beijing Jishuitan Hospital between January 2012 and December 2022. Results This study included 1321 patients [aged 47.19 ± 14.90 years, 603 (45.65%) males] with spinal intradural tumors. The most common histological subtype was schwannoma [n = 511 (38.68%)], followed by spinal meningioma [n = 184 (13.93%)] and ependymoma [n = 101 (7.65%)]. Fifteen (1.14%) patients were diagnosed with metastatic spinal intradural tumors as a presentation of another primary cancer type. The spinal intradural tumors were mostly found in the lumbar region [n = 436 (33.01%)], followed by the thoracic vertebrae [n = 390 (29.52%)], cervical vertebrae [n = 154 (11.66%)], and thoracolumbar region [n = 111 (8.40%)]. Schwannomas mostly affected the lumbar region [n = 256 (52.64%)], spinal meningiomas in the thoracic region [n = 153 (83.15)], and ependymomas in the lumbar region [56 (55.45%)]. The de novo metastases were mostly found in the lumbar region [n = 8 (53.33%)]. Conclusion According to the results of our single-center study, the most common spinal intradural tumor in Northern China is schwannoma, followed by spinal meningioma and ependymoma.

Objective Currently, there is no established guideline on whether to opt for percutaneous endoscopic lumbar discectomy (PELD) or traditional transforaminal lumbar interbody fusion (TLIF) surgery based on specific types of lumbar disc herniation (LDH). Based on the Michigan State University (MSU) classification system, this study conducted a medium‐ to long‐term follow‐up analysis of two surgical methods over 5 years for the first time, aiming to provide empirical evidence to assist in making more informed decisions before surgery for LDH treatment. Methods This was a retrospective study that included 273 patients with single‐level LDH who underwent PELD or TLIF treatment at our hospital between January 1, 2016, and December 31, 2018. Detailed metrics included preoperative and postoperative visual analogue scale (VAS) scores and Oswestry disability index (ODI) at 1‐day, 1‐week, 1‐year, and 5‐year follow‐ups. Complications, recurrences, and 5‐year postoperative modified MacNab criteria scores were also recorded. Statistical methods included independent sample t‐tests, repeated measures analysis of variance (ANOVA), and χ2 tests. Results Classified into seven groups according to the MSU classification, it was found that there was an improvement in the VAS and ODI scores at four postoperative follow‐ups (p

Introduction: The winter climate in Delhi is severe, with temperatures dropping below 10°C. As a result, individuals often resort to utilizing diverse heat sources such as electrical heating appliances, coal and gas geysers. Unfortunately, these sources are commonly associated with the emission of carbon monoxide (CO) which can accumulate in inadequately ventilated spaces. Exposure to this noxious gas can lead to acute lethargy and debilitation, leaving individuals in a state of helpless distress. Materials and Methods: The present study utilized a retrospective descriptive analysis to examine cases of fatal carbon monoxide exposure retrieved from the Department of Forensic Medicine archives at the esteemed All India Institute of Medical Sciences, New Delhi. Autopsy records were thoroughly examined with respect to various parameters including age, gender, seasonality of the incident, circumstances surrounding the death, source of carbon monoxide generation, post mortem observations, as well as toxicological analysis reports. Results and Discussion: This study entailed an analysis of 56 individuals who fell victim to carbon monoxide poisoning, with a staggering 95% of fatalities occurring during the winter season. The majority of the individuals affected belonged to the age bracket of 21–30 years. The most common sources of carbon monoxide exposure were linked to the use of coal-burning earthen or iron vessels for room heating, as well as structural fires. With the exception of one case, all incidents were accidental in nature. Additionally, nearly all of the victims were discovered in enclosed spaces with heating equipment in close proximity, and evidence of a struggle was noted on the crime scene or with the deceased. Conclusion: The findings of this study indicate that the principal contributor to the inadvertent build-up of lethal concentrations of carbon monoxide gas is the utilization of heating appliances within inadequately ventilated, enclosed spaces. Due to the scentless and non-irritating properties of this gas, individuals who are asleep may be unable to detect its presence in their surroundings, thereby leading to a silent death. To mitigate such risks, the installation of carbon monoxide detectors is crucial. Additionally, it is of utmost importance to raise public awareness regarding the perils associated with using fire pots, coal burning and electrical heating appliances in areas with insufficient ventilation.

Multivariate Cox proportional hazard regression models were used to identify potential risk factors. A prognostic nomogram was developed based on the multivariate analyses. The receiver operating characteristic curve determined the optimal cutoff value for AGR.Results: The results indicated a statistically significant decrease in AGR among patients with BC. Significant disparities were observed in globulin and AGR levels between the two cohorts. AGR was significantly associated with tumor size and stage, with a marked decline in advanced stages of BC. Additionally, AGR and aspartate transaminase/Alanine aminotransferase (AST/ALT) emerged as significant diagnostic indicators for invasive carcinoma and advanced stages (II–IV) of BC. Specifically, AGR exhibited an area under the curve of 0.645 (P < 0.003), highlighting the discriminatory capacity of serum globulin levels in distinguishing between BC and non-BC cohorts.Conclusions: The AGR, routinely assessed due to its simplicity, objectivity, and cost-effectiveness, holds promise as a potential risk factor for BC and may have practical implications in clinical settings.Keywords: albumin to globulin ratio, risk factor, breast cancer, retrospective study

Abstract Objectives This study aimed to comprehensively analyze the prevalence and influencing factors of Zygomatic Air Cell Defects (ZACD) among pediatric and adolescent populations in Saudi Arabia and Yemen. Materials and methods A cross-sectional retrospective study was conducted, utilizing digital panoramic radiographs of dental outpatients aged 6 to 18 years. The data were collected from registered digital databases of dental clinics in Al-Qassim, Saudi Arabia, and an oral and maxillofacial radiology center in Sana’a, Yemen, covering the period from July 2018 to September 2022. The radiographs were evaluated based on inclusion and exclusion criteria, and ZACD was assessed using standardized descriptions. Statistical analysis, including logistic regression, was employed to examine the impact of the associated factors. Results The study encompassed a total of 3,169 participants, revealing an overall ZACD prevalence of 28.5%. Age emerged as a significant predictor (p ≤ 0.0001), with the likelihood of ZACD increasing as the age of the individual advances. Gender and geographic region did not exhibit statistically significant differences in ZACD prevalence. Conclusion This study provides crucial insights into the prevalence of Zygomatic Air Cell Defects among pediatric and adolescent populations in Saudi Arabia and Yemen. It underscores the prevalence of ZACD and the notable influence of age on its occurrence. Additionally, the research challenges prior notions of gender and regional variations in ZACD prevalence, emphasizing the complexity of the factors involved. Early detection is essential to avoid unwanted complications during any surgical intervention in this area.

The aim of this study was to evaluate eradication outcomes in clinical practice and identifies factors contributing to treatment failure.Methods: A retrospective review was conducted on patients treated for H. pylori infection with 14-day bismuth-containing quadruple therapy at a Beijing medical center from January 2020 to December 2023. We analyzed demographic and clinical data, eradication rates across regimens, and performed multivariate analysis to pinpoint predictors of failure.Results: Out of 3340 participants, 2273 (68.1%) achieved eradication. Amoxicillin-based combinations (69.2%) outperformed other antibiotic regimens (58.9%, p < 0.001), with amoxicillin plus doxycycline reaching a 71.4% success rate. Esomeprazole-based regimens were more effective (73.6%) than other PPI regimens (65.2%, p = 0.001), notably, a rabeprazole, amoxicillin, doxycycline, and bismuth combination had an 80.0% success rate. Age, gender, and smoking and drinking were significant eradication failure predictors.Conclusion: In real-world settings, 14-day amoxicillin and esomeprazole-based quadruple regimens have been demonstrated to be more effective than other regimens. Age, gender, and lifestyle habits are identified as independent risk factors for eradication failure.Registration: This study was registered in the Chinese Clinical Trial Registry on 08/01/2024 (clinical trial registration number: ChiCTR2400079647).Keywords: Helicobacter pylori, quadruple therapy, antibiotics, proton pump inhibitor, retrospective study

After retrospectively gathering demographic information, clinical data such as qEEG, Positive and Negative Syndrome Scale (PANSS), a multiple regression analysis was performed. This analysis employed baseline qEEG findings as independent variables and PANSS score changes as dependent variables to discern causal relationships.Results: The mean age of the participants was 38.4 years(SD =13.73). The mean PANSS score on admission was 92.97, decreasing to 67.41 at discharge. Multiple regression analysis revealed that delta waves in T4 (β=0.346, t=3.165, p=0.002), and high-beta waves in Fp2 (β=0.231, t=2.361, p=0.021) were associated with PANSS changes in absolute power. In addition, the delta waves of O2 (β=0.250, t=3.288, p=0.002); beta waves of T3 (β=− 1.463, t=− 5.423, p< 0.001) and O2 (β=0.551, t=3.366, p=0.001); high beta waves of Fp1 (β=0.307, t=4.026, p< 0.001), T3 (β=0.855, t=4.414, p< 0.001) and T6 (β=− 0.838, t=− 4.559, p< 0.001) of absolute power using the Z-score were also related to PANSS changes. Pearson’s correlation analysis showed that only delta waves at Cz (r= 0.246, p=0.043) in absolute power correlated with changes in the PANSS.Conclusion: We found that certain qEEG wave patterns in patients with schizophrenia prior to antipsychotic treatment were linked to PANSS changes before and after treatment. Delta waves and beta waves, primarily in the frontal and temporal regions, were found to be significantly associated with changes in PANSS scores. In the future, the qEEG indicators identified in this study could serve as electrophysiological markers for predicting antipsychotic treatment responses in patients with schizophrenia.Keywords: schizophrenia, treatment response, quantitative electroencephalography, electrophysiological marker, retrospective study

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

Aim The aim of this study was to examine the imaging manifestations of post-endoscopic retrograde cholangiopancreatography (ERCP) specific complications by computed tomography to aid in its early and successful diagnosis and timely intervention.

Background: Pediatric procedural dermatology is a broad and emerging aspect in the field of dermatology. Pediatric procedures require great expertise, skill, empathy, and confidence on the part of the treating physician. The challenging factors such as parental anxiety and doubts, the child’s cooperation, and the risks versus benefits are further contributory. Objective: The objective of the study was to summarize the risks of intra- and postoperative complications/side effects during diagnostic and therapeutic procedure in the pediatric population. Materials and Methods: We conducted a retrospective study in our hospital. Patients were taken between ages 0 and 18 years who had attended the dermatology outpatient department from January 2019 to March 2022. Results: In a total of 527 outpatient department patients, 267 (50.66%) were males and 260 (49.33%) were females (male:female ratio 1.02:1). Out of diagnostic procedures, the most commonly performed procedures were punch biopsy (14.61%), followed by autologous serum skin test (11.81%) and slit-skin smear (1.90%). Out of 15 therapeutic procedures, intralesional steroids (21.34%) were the most frequently performed therapeutic procedure, followed by radiofrequency cauterization (16.51%), autologous skin therapy (6.98%), cryotherapy (8.76%), nail surgery (2.79%), chemical peeling (2.79%), comedone extraction (2.66%), chemical cauterization (2.54%), neodymium-doped yttrium aluminum garnet laser (2.16%), platelet-rich plasma therapy (1.39%), diode laser (1.27%), measles, mumps, and rubella vaccine injection (0.89%), fractional carbon dioxide laser (0.63%), suction blister epidermal grafting (0.63%), and platelet-rich fibrin therapy (0.25%). Conclusions: This study provided comprehensive data on the various dermatological procedures done for pediatric cases in a tertiary care teaching hospital. Both diagnostic and therapeutic procedures caused mild and transient side effects such as pain, edema, erythema, burning sensations, and irritation that did not affect the patient’s lifestyle.

Abstract Objective We aimed to examine the factors associated with treatment outcomes in patients with Alzheimer's disease (AD) after 1 year of acetylcholinesterase inhibitors (AChEI) treatment. Method We obtained electronic medical records from a medical center in Southern Taiwan between January 2015 and September 2021. Participants aged ≥60 who were newly diagnosed with AD and had been prescribed AChEIs were included. Cognitive assessments were performed before the AChEIs were prescribed and at the 1 year follow‐up. Cognition progressors were defined as a Mini‐Mental State Examination decline of >3 or a Clinical Dementia Rating decline of ≥1 after 1 year of AChEI treatment. The relationship between the baseline characteristics and cognitive status after follow‐up was investigated using logistic regression analysis after adjusting for potential confounders. Results A total of 1370 patients were included in our study (mean age, 79.86 ± 8.14 years). After adjustment, the body mass index (BMI) was found to be significantly lower in the progressor group [adjusted odds ratio (AOR): 0.970, 95% confidence intervals (95% CIs): 0.943 to 0.997, P = 0.033]. The usage of antipsychotics was significantly higher in the progressor group (AOR: 1.599, 95% CIs: 1.202 to 2.202, P = 0.001). The usage of benzodiazepine receptor agonists also tended to be significantly higher in the progressor group (AOR: 1.290, 95% CIs: 0.996 to 1.697, p = 0.054). Conclusion These results suggest that patients with AD who receive 1 year of AChEI treatment and have a lower BMI or concurrent treatment with antipsychotics and benzodiazepine receptor agonists are more likely to suffer from cognitive decline.

Abstract This study aimed to evaluate the clinical efficacy of percutaneous coaxial large-channel endoscopic lumbar interbody fusion (PCLE-LIF) and transforaminal lumbar interbody fusion (TLIF) in the treatment of degenerative lumbar spinal stenosis. The clinical data of patients with degenerative lumbar spinal stenosis who underwent PCLE-LIF (experimental group) and TLIF (control group) surgery from September 2019 to September 2021 were retrospectively analyzed. We collected clinical data and compared the two groups in terms of perioperative parameters, treatment response rate, inflammatory response markers, postoperative complications, postoperative pain, and functional recovery. The results showed that the treatment outcomes in the experimental group were significantly better than those in the control group. Specifically, perioperative parameters and inflammatory response markers in the experimental group were significantly better than those in the control group, with statistically significant differences (P

Abstract Background Indoor residual spraying (IRS) has been implemented to prevent malaria in Zambia for several decades, but its effectiveness has not been evaluated long term and in Vubwi District yet. This study aimed to assess the association between IRS and the malaria burden in Zambia and Vubwi District and to explore the factors associated with refusing IRS. Methods A retrospective study was used to analyze the association between IRS and malaria incidence in Zambia in 2001–2020 and in Vubwi District in 2014–2020 by Spearman correlation analysis. A case-control study was used to explore the factors associated with IRS refusals by households in Vubwi District in 2021. A logistic regression model was performed to identify factors associated with IRS refusals. Results The malaria incidence reached its peak (391/1000) in 2001 and dropped to the lowest (154/1000) in 2019. The annual percentage change in 2001–2003, 2003–2008, 2008–2014, 2014–2018 and 2018–2020 was − 6.54%, − 13.24%, 5.04%, − 10.28% and 18.61%, respectively. A significantly negative correlation between the percentage of population protected by the IRS against the total population in Zambia (coverage) and the average malaria incidence in the whole population was observed in 2005–2020 (r = − 0.685, P = 0.003) and 2005–2019 (r = − 0.818, P

Abstract Background At present, research comparing the short-term postoperative outcomes of anatomical resection in lung cancer under different ports of da Vinci robot-assisted surgery is insufficient. This report aimed to compare the outcomes of three-port and four-port da Vinci robot-assisted thoracoscopic surgery for radical dissection of lung cancer. Methods 171 consecutive patients who presented to our hospital from January 2020 to October 2021 with non-small cell lung cancer and treated with da Vinci robot-assisted thoracoscopic surgery for radical resection of lung cancer were retrospectively collected and divided into the three-port group (n = 97) and the four-port group (n = 74). The general clinical data, perioperative data and life quality were individually compared between the two groups. Results All the 171 patients successfully underwent surgeries. Compared to the four-port group, the three-port group had comparable baseline characteristics in terms of age, sex, tumor location, tumor size, history of chronic disease, pathological type, and pathological staging. The three-port group also had shorter operation time, less intraoperative blood loss, lower chest tube drainage volume, shorter postoperative hospitalization stay durations, but showed no statistically significant difference (P > 0.05). Postoperative 24, 48 and 72 h visual analogue scale pain scores were lower in the three-port group (p 0.05) and postoperative respiratory complications (P > 0.05). Conclusions The three-port robot-assisted thoracoscopic surgery is safe and effective and took better outcomes than the four-port robot-assisted thoracoscopic surgery in non-small cell lung cancer.

Abstract Introduction To explore the diagnostic value of high-resolution ultrasound combined with multi-slice computer tomography (MSCT) for pediatric intra-abdominal hernias (IAHs), and to analyze the potential causes for missed diagnosis and misdiagnosis of IAHs in children. Methods A retrospective analysis was conducted on 45 children with surgically confirmed IAHs. The diagnostic rate of IAHs by preoperative high-resolution ultrasound combined with MSCT was compared with that of intraoperative examination, and the potential causes for missed diagnosis and misdiagnosis by the combination method were analyzed. Results Forty-five cases of pediatric IAHs were categorized into primary (25/45, 55.5%) and acquired secondary hernias (20/45, 44.5%). Among children with primary hernias, mesenteric defects were identified as the predominant subtype (40%). Acquired secondary hernias typically resulted from abnormal openings in the abdominal wall or band adhesions due to trauma, surgery, or inflammation. In particular, adhesive band hernias were the major type in children with acquired secondary hernias (40%). The diagnostic rate of high-resolution ultrasound was 77.8%, with “cross sign” as a characteristic ultrasonic feature. Among 10 cases of missed diagnosis or misdiagnosis, 5 were finally diagnosed as IAHs by multi-slice computer tomography (MSCT). Overall, the diagnostic rate of pediatric IAHs by preoperative ultrasound combined with radiological imaging reached 88.9%. Discussion IAHs in children, particularly mesenteric defects, are prone to strangulated intestinal obstruction and necrosis. High-resolution ultrasound combined with MSCT greatly enhances the diagnostic accuracy of pediatric IAHs.
