Levoleucovorin injection enhances the toxicity of 5-fluorouracil. Deaths from severe enterocolitis, diarrhea, and dehydration have been reported in elderly patients receiving weekly d,l-leucovorin and 5-fluorouracil. When these drugs are administered concurrently in the palliative treatment of advanced colorectal cancer, the dosage of 5-FU must be lower than usually administered. Although the toxicities observed in patients treated with the combination of levoleucovorin injection and 5-FU are qualitatively similar to those observed with 5-FU alone, gastrointestinal toxicities (particularly stomatitis and diarrhea) are observed more commonly and may be of greater severity and of prolonged duration in patients treated with the combination.

In the first Mayo/NCCTG controlled trial, toxicity, primarily gastrointestinal, resulted in 7% of patients requiring hospitalization when treated with 5-FU alone or 5-FU in combination with 200 mg/m2 of d,l-leucovorin and 20% when treated with 5-FU in combination with 20 mg/m2 of d,l-leucovorin. In the second Mayo/NCCTG trial, hospitalizations related to treatment toxicity also appeared to occur more often in patients treated with the low dose d,l-leucovorin/5-FU combination than in patients treated with the high dose combination – 11% versus 3%. Therapy with levoleucovorin injection and 5-FU must not be initiated or continued in patients who have symptoms of gastrointestinal toxicity of any severity, until those symptoms have completely resolved. Patients with diarrhea must be monitored with particular care until the diarrhea has resolved, as rapid clinical deterioration leading to death can occur. In an additional study utilizing higher weekly doses of 5-FU and d,l-leucovorin, elderly and/or debilitated patients were found to be at greater risk for severe gastrointestinal toxicity. 

Seizures and/or syncope have been reported rarely in cancer patients receiving d,l-leucovorin, usually in association with fluoropyrimidine administration, and most commonly in those with CNS metastases or other predisposing factors. However, a causal relationship has not been established.
BACKGROUND: We investigated the impact of the COVID-19 pandemic on trends of presentation, management and pathology findings in patients who underwent an appendicectomy for suspected acute appendicitis.
METHOD: The retrospective study reviewed patients (n = 939 adults and n = 329 children) who had an appendicectomy performed for suspected acute appendicitis and histopathology assessment in the Belfast Health and Social Care Trust, Northern Ireland. Pre-COVID-19 (March 2019 to February 2020) and COVID-19 Year 1 (March 2020 to February 2021) data were compared. Chi-squared tests were applied to compare timeframes.
RESULTS: 513 adult appendicectomies were performed in the immediate year pre-COVID-19, compared to 426 in COVID-19 Year 1, representing a 17% reduction. No such reduction was seen within the paediatric population, likely related to a change in regional paediatric referral criteria during the pandemic. When comparing COVID-19 Year 1 with pre-pandemic, fewer patients presented with <24 hours of symptoms (45% v 53%, p = 0.005), and there was greater use of pre-operative computed tomography imaging in adults (63.2% v 48.7%, p<0.001). Fewer adult and paediatric cases of simple acute appendicitis and non-diagnostic specimens, with relative increased proportions of perforated acute appendicitis, were observed in COVID-19 Year 1 compared with pre-pandemic. No absolute increase in perforated acute appendicitis cases was observed in adults.
CONCLUSION: Year 1 of the COVID-19 pandemic was associated with delayed presentation of acute appendicitis in adults and children. In adults, an overall reduction in appendicectomy operations, increased use of pre-operative diagnostic imaging, and fewer specimens showing simple acute appendicitis or non-diagnostic features, collectively support appropriate restriction of surgery for those patients with a more certain acute appendicitis diagnosis.
Melphalan, also known as L-phenylalanine mustard, phenylalanine mustard, L-PAM, or L-sarcolysin, is a phenylalanine derivative of nitrogen mustard. Melphalan is a bifunctional alkylating agent that is active against selected human neoplastic diseases. It is known chemically as 4-[bis(2-chloroethyl)amino]-L-phenylalanine. The molecular formula is C13H18Cl2N2O2 and the molecular weight is 305.20. The structural formula is: 

Melphalan is the active L-isomer of the compound and was first synthesized in 1953 by Bergel and Stock; the D-isomer, known as medphalan, is less active against certain animal tumors, and the dose needed to produce effects on chromosomes is larger than that required with the L-isomer. The racemic (DL-) form is known as merphalan or sarcolysin. 

Melphalan is practically insoluble in water and has a pKa1 of ~2.5. 

Melphalan hydrochloride for injection is supplied as a sterile, nonpyrogenic, freeze-dried powder. Each single-dose vial contains melphalan hydrochloride equivalent to 50 mg melphalan and 20 mg povidone. Melphalan hydrochloride for injection is reconstituted using the sterile diluent provided. Each vial of sterile diluent contains sodium citrate 0.2 g, propylene glycol 6 mL, ethanol (96%) 0.52 mL, and water for injection to a total of 10 mL. Melphalan hydrochloride for injection is administered intravenously.
UNLABELLED: Intramedullary stem extensions are typically added to the femoral and tibial components during revision total knee arthroplasty (TKA) to augment fixation of the components and improve survivorship. A commonly used option includes hybrid fixation with cement at the interface between the component and the host bone combined with cementless diaphyseal fitting stems. Radiographic sclerotic lines may appear with these constructs over time, and it is unclear if this finding has implications relative to implant survivorship. The purpose of this study was to quantify the prevalence of sclerotic lines at the bone-implant interface and assess the impact of progressive sclerotic lines on revision for aseptic loosening.
METHODS: A retrospective chart review of a consecutive series of patients who underwent revision TKA at a single tertiary care institution between January 2001 and December 2009 was performed. Data were collected regarding patient demographics, stem size, types of implants, and complications. Radiological reports and radiographs were evaluated for sclerotic lines, propagation, and their location around the tibial stem. Aseptic loosening rates were compared between patients with and without sclerotic lines.
RESULTS: One hundred and fifty-three patients with at least 15 years of follow-up were identified. The mean follow-up was 16.5 ± 4.12 years (range 15-23). Overall, 19 patients required re-revision surgery. Survivorship free of failure due to aseptic loosening was 94.8% (95% CI 76.4-98) at 15 years, with three patients requiring re-revision surgery for aseptic loosening. Twelve (7.8%) patients were found to have sclerotic lines surrounding the tibial stem, all under 2 mm in width. Two (1%) patients with sclerotic lines required re-revision surgery, one patient due to infection and one due to aseptic loosening. There was no significant difference in rates of aseptic loosening in patients with or without sclerotic lines.
CONCLUSION: Radiographic sclerotic lines around revision TKA stems-measuring less than 2mm wide, nonprogressive, and located at the lateral-distal aspect of the stem-were identified in fewer than 8% of cases and did not correlate with re-revision surgery.
In this study, we present a novel surgical method that utilizes the ultrasonic bone scalpel (UBS) for the removal of large retrovertebral osteophytes in anterior cervical discectomy and fusion (ACDF) and evaluate its safety and efficacy in comparison to the traditional approach of using high-speed drill (HSD). A total of 56 patients who underwent ACDF for retrovertebral osteophytes were selected. We recorded patients' baseline information, operation time, intraoperative blood loss, complications, JOA and VAS scores, and other relevant data. The mean operation time and the mean intraoperative blood loss in the UBS group were less than those in the HSD group (P < 0.05). Although both groups exhibited considerable improvements in JOA and VAS scores following surgery, there was no statistically significant difference between the two groups (P > 0.05). Additionally, no significant disparities were found in bone graft fusion between the two groups at 6- and 12-months postsurgery. Notably, neither group exhibited complications such as dura tear or spinal cord injury. Our study found that the use of UBS reduced operative time, minimized surgical bleeding, and led to clinical outcomes comparable to HSD in ACDF. This technique offers an effective and safe method of removing large retrovertebral osteophytes.
After a 13 h overnight fast, participants will rest in the laboratory for the duration of the trial (09:00-11:00). A standardised meal will be consumed at 10:00 which will provide 5025 kJ energy (47% carbohydrate, 9% protein, 44% fat).
The present invention relates to a liquid crystal display device, which includes a display module and a first frame, which includes a plurality of side walls. A flexible configuration is disposed onto the inner surface of at least one of the side walls. The flexible configuration includes a flexible arm, a contact part which is connected to the flexible arm, and a resistive part which is disposed at one end of the contact part. The resistive part keeps a distance to the inner surface of the side wall. When the pressure to the flexible arm is unbearable, the resistive part sticks up to the side wall in order to prevent the flexible arm from breaking off. The back case can cooperate with different standard display panel and needn't to redesign the plastic mould.
Radiotherapy (RT) is one of the important treatment modalities for non-small cell lung cancer (NSCLC). However, the maximum radiation dose that NSCLC patient can receive varies little. Therefore, the exploitation of novel RT sensitization approaches is a critical need for the clinical treatment. RT resistance in NSCLC is linked to tumor microenvironment (TME) hypoxia, cell cycle arrest and associated genetic alterations. Here, we designed a novel method for targeted delivery of quercetin (QT) and CeO2 to enhance RT sensitivity. We loaded QT into CeO2@ZIF-8-HA nanoparticles to prevent its degradation in the circulatory system and successfully delivered QT and CeO2 targeted to NSCLC tumors. Under the protection and targeted delivery of Zeolitic Imidazolate Framework-8 (ZIF-8), the nanocomplexes exhibited excellent catalytic mimetic activity in decomposing H2O2 into O2, thus significantly reversing the hypoxia of TME, while the radiosensitizer QT caused DNA damage directly after RT. In a subcutaneous tumor model, CeO2@ZIF-8-HA overcame radiation resistance and enhanced therapeutic efficacy. This multiple sensitization strategy combining delivery of QT and CeO2@ZIF-8-HA nanozymes opens a promising approach for RT of NSCLC.
A method is disclosed for making an artificial micro-gland having a continuous anisotropic membrane of two or more types of living cells. A first step includes forming a carrier fluid in a microchannel in a laminar flow of two distinct fluid flows. Another step includes introducing a template, which may itself be anisotropic, into the microchannel in a manner such that the template straddles the interface between the first fluid-flow and the second fluid-flow. In some embodiments two types of living cells within the template are separately attracted one of the fluid flows by the presence of an agent of taxis. In other embodiments, cells within one or the other of the fluid flows are attracted to agents within the template. Membranes form on the template and join together to form a complete cellular membrane around a reservoir.
BACKGROUND: The most common subtype of borderline ovarian tumors in Asia is mucinous borderline ovarian tumors (mBOTs). Intraoperative distinction from mucinous carcinoma can be difficult. Despite the indolent behavior of mBOTs, recurrence or metastases may occur. The objectives of this study were to determine the oncological outcomes of mBOTs and the risk factors for their recurrence.
RESULTS: This retrospective study enrolled patients with mBOTs treated or referred to our institution between January 2005 and December 2019. Histological reviews of the recurrent cases (primary and recurrent or metastatic tumors) were performed. Patients with other tumor subtypes, pseudomyxoma peritonei, or no in-house operation were excluded. Two hundred thirty-two patients were diagnosed with mBOTs. The median follow-up was 52 months. Six patients (2.58%) had tumor recurrence or metastasis. The risk factors for recurrence were a ruptured tumor, residual tumor after an operation, high serum CA19-9 level, and stage of the disease. The recurrence rates of fertility-sparing and radical surgery were not significantly different. Detailed surgical staging, intraepithelial carcinoma, and microinvasion were also not associated with disease recurrence.
CONCLUSIONS: mBOTs have an excellent prognosis. Currently, fertility-sparing surgery is the standard treatment, showing no significant difference in oncological outcomes compared to radical surgery. Patients with risk factors should be closely monitored.
For participants in Treatment-As-Usual (TAU) group measures are obtained at baseline and 42 days later. Participants receive an approximately 10 minutes long introduction regarding study specifications and the mHealth application. Active participation in TAU group is defined as downloading the Sidekick app and completing at least 3 health exercises within it. Time of exercise is defined as the timestamp on completion of exercise within any of the three types of exercise categories (physical activity, nutrition and mental health) of the app. Exercise frequency refers to how often a given exercise was completed by a participant in TAU group. Time of attrition is defined as the time stamp of last completing health exercise within the Sidekick throughout intervention period. Participants in TAU group use the application individually throughout trial period without any motivational support.
To evaluate the clinical significance of PLT, MPV, and PDW in monitoring malaria treatment efficacy and predicting disease progression. A total of 31 patients with imported malaria were selected as the observation group, while 31 non-malaria patients with fever were selected as controls. The observation group was subdivided into a complication group and a non-complication group according to the occurrence of complications during treatment. Additionally, on the 1st day (within 24 h), the 3rd day, and the 5th day following admission, a comprehensive blood routine examination, Plasmodium microscopic examination, and colloidal gold assay were conducted. The blood routine examination results were compared before and after treatment among patients in the observation group and the control group. Moreover, the study involved dynamic monitoring and analysis of the levels and variations in PLT, MPV, and PDW within both the complication group and the non-complication group. The Plasmodium density was negatively correlated with PLT before treatment. There were significant differences were observed in PLT, MPV, and PDW (P < 0.05) within the observation group before and after treatment. Notably, there were no significant alterations in red blood cell (RBC), hemoglobin (Hb), and white blood cell (WBC) counts (P > 0.05) within the observation group before and after treatment. The PLT, MPV, and PDW levels in the complication group and the non-complication group exhibited an upward trend after treatment. Further, the PLT of patients in the complication group was significantly lower than that in the non-complication group. Additionally, the PLT, MPV, and PDW levels in the complication group and the non-complication group increased gradually from the time of admission to the 3rd and 5th day of treatment. Notably, the PLT in the complication group was consistently lower than that in the non-complication group. The continuous monitoring of PLT, MPV, and PDW changes plays a crucial role in assessing malaria treatment efficacy and prognosis in these individuals.
B and T cells often target checkpoint receptors and their cognate ligands in autoimmune diseases, where these adaptive immune responses may contribute significantly to the underlying immunopathology. Described herein are novel techniques for clonal depletion of autoreactive B cells that target checkpoint receptors and their ligands. One embodiment of this technology is a molecular chimera with checkpoint receptors or ligand ectodomains of the effector domain, which are capable of inducing B-cell apoptosis, necrosis and/or tolerance/no response: this technique is referred to herein as PantId (polyclonal anti-idiotype). In other embodiments, the technology further comprises chimeras with effector molecules of immunomodulatory cytokines. Novel apoptotic effectors are also described. Methods of identifying checkpoint receptor/ligand autoreactive B cell responses, constructing PantId, and in vitro and in vivo applications thereof are also described.

Demographic information of all subjects (age, gender, educational status, occupation, body weight, height, body mass index), clinical (diagnosis period) and medical status, personal history and family history, COPD stage, COPD Assessment Test (CAT) score, emergency and hospital admissions numbers in the last 3 months, exacerbation and hospitalization numbers in the last one year were recorded. Respiratory and peripheral muscle strengths are evaluated. Also pulmonary functions test results obtained.
BACKGROUND: During the prolonged period from Human Papillomavirus (HPV) infection to cervical cancer development, Low-Grade Squamous Intraepithelial Lesion (LSIL) stage provides a critical opportunity for cervical cancer prevention, giving the high potential for reversal in this stage. However, there is few research and a lack of clear guidelines on appropriate intervention strategies at this stage, underscoring the need for real-time prognostic predictions and personalized treatments to promote lesion reversal.
METHODS: We have established a prospective cohort. Since 2018, we have been collecting clinical data and pathological images of HPV-infected patients, followed by tracking the progression of their cervical lesions. In constructing our predictive models, we applied logistic regression and six machine learning models, evaluating each model's predictive performance using metrics such as the Area Under the Curve (AUC). We also employed the SHAP method for interpretative analysis of the prediction results. Additionally, the model identifies key factors influencing the progression of the lesions.
RESULTS: Model comparisons highlighted the superior performance of Random Forests (RF) and Support Vector Machines (SVM), both in clinical parameter and pathological image-based predictions. Notably, the RF model, which integrates pathological images and clinical multi-parameters, achieved the highest AUC of 0.866. Another significant finding was the substantial impact of sleep quality on the spontaneous clearance of HPV and regression of LSIL.
CONCLUSIONS: In contrast to current cervical cancer prediction models, our model's prognostic capabilities extend to the spontaneous regression stage of cervical cancer. This model aids clinicians in real-time monitoring of lesions and in developing personalized treatment or follow-up plans by assessing individual risk factors, thus fostering lesion spontaneous reversal and aiding in cervical cancer prevention and reduction.
Fungal bezoars (fungal balls) are rarely reported in the upper or lower urinary tract. They can be the cause of severe morbidities such as urinary tract obstruction, renal failure and fungaemia. Hereby, we present a rare case of a male patient who underwent transurethral resection of bladder tumour (TURBT), and during his postoperative period, he was diagnosed with bladder fungal bezoars adherent to his resection area. The fungal bezoars were covering an extended area of the right lateral bladder wall, including the right ureteric orifice and causing right urinary tract obstruction. Those findings were manifested only after a relooked cystoscopy and histological evaluation.We aim to present a rare example of fungal bezoars mimicking other pathologies in the urinary tract and review the current literature for similar documentation. We underline the necessity of follow-up examinations for urologists performing TURBT surgeries, including urinalysis, imaging modalities and cystoscopy.
Intervention group (n = 16 nursing homes, 64 patients): Patients in the interventional group will be monitored using the capillary International Normalised Ratio strategy every week, and more often if the International Normalised Ratio is not in the therapeutic target. Venous International Normalised Ratio punctures will also be performed as described for the control group in order to calculate the Time in Therapeutic Range equivalently in both groups. Specific training in handling the device and the dose adjustment protocol will be provided to nurses and prescribers.
