BACKGROUND: MRI has been widely used to predict the preoperative proliferative potential of pituitary adenoma (PA). However, the relationship between the cyst/tumor volume ratio (C/T ratio) and the proliferative potential of PA has not been reported. Herein, we determined the predictive value of the C/T ratio of PA for tumor cell proliferation.
METHODS: The clinical data of 72 patients with PA and cystic change on MRI were retrospectively analyzed. PA volume, cyst volume, and C/T ratio were calculated. The corresponding intraoperative specimens were collected. Immunohistochemistry and hematoxylin-eosin staining were performed to evaluate the Ki67 index and nuclear atypia. Patients were categorized according to the Ki67 index (< 3% and ≥ 3%) and nuclear atypia (absence and presence). Univariate and multivariate analyses were used to identify the significant predictors of the Ki67 index and nuclear atypia. The receiver operating characteristic curve assessed the prediction ability of the significant predictors.
RESULTS: Larger tumor volumes, smaller cyst volumes, and lower C/T ratios were found in patients with higher Ki67 indexes and those with nuclear atypia (P < 0.05). C/T ratio was an independent predictor of the Ki67 index (odds ratio = 0.010, 95% confidence interval = 0.000-0.462) and nuclear atypia (odds ratio = 0.010, 95% confidence interval = 0.000-0.250). The predictive value of the C/T ratio did not differ significantly from that of tumor volume (P > 0.05) but was better than that of cyst volume (P < 0.05). The area under the curve of the C/T ratio for predicting the Ki67 index and nuclear atypia was larger than that for predicting cyst volume and tumor volume.
CONCLUSIONS: C/T ratios can be used to predict PA tumor proliferation preoperatively. Our findings may facilitate the selection of surgery timing and the efficacy evaluation of surgery.
Reduced myelin stability observed in the early stages of Alzheimer's disease leads to spatial learning and memory impairment. Exercise has been shown to protect nerves, reduce the risk of Alzheimer's disease, and strengthen synaptic connectivity. However, the underlying mechanisms of how exercise can promote myelin repair and coordinate inflammation and proliferation are still uncertain. In this study, we conducted histological and biochemical assays of cortical lysates after behavioral testing to detect pathological changes, myelin sheath thickness, and mRNA and protein levels. It is notable that D-galactose model mice exhibited elevated miRNA-34a levels, overactive astrocytes, decreased myelin staining scores, increased apoptosis, and decreased synaptic plasticity in the brain. Significantly, after eight weeks of exercise, we observed improvements in LFB scores, NeuN( +) neuron counts, and myelin basic protein (MBP) expression. Additionally, exercise promoted the expression of oligodendrocyte markers Olig2 and PDFGR-α associated with brain proliferation, and improved spatial cognitive function. Furthermore, it decreased the inflammation caused by astrocyte secretions (TNF-α, Cox-2, CXCL2). Interestingly, we also observed downregulation of miR-34a and activation of the TAN1/PI3K/CREB signaling pathway. Our data shed light on a previously unsuspected mechanism by which exercise reduces miR-34a levels and protects neuronal function and survival by preventing excessive demyelination and inflammatory infiltration in the CNS.
Among women with premenstrual mood dysphoric disorder (PMDD), baseline arousal is heightened during the luteal phase of the menstrual cycle compared to the follicular phase, as measured by acoustic startle response (ASR). Healthy female controls do not show cyclic changes in this measure of physiologic arousal. It has been suggested that such heightened physiologic arousal during the luteal phase may be due to differences in neurosteroid modulation of Gamma-aminobutyric acid (GABA)-A receptor function. Research indicates that women with premenstrual mood disorders (PMDs) may have sub-optimal sensitivity to the progesterone metabolite allopregnanolone (ALLO), a GABA-A receptor modulator. In animal models, intracerebroventricular injection of corticotrophin releasing factor (CRF) increases amplitude of the acoustic startle response, while ALLO administration attenuates this CRF-enhanced startle. The primary aim of this study is to examine differences in ASR by menstrual cycle phase (follicular, luteal) and group (control, PMDD). Secondary aim is to examine the impact of luteal phase treatment with a selective serotonin reuptake inhibitor (SSRI) on psychophysiology in women with PMDs. An exploratory aim is to examine immune function among these women.
There are no established maintenance protocols for cutaneous lymphomas. We aim to determine patient treatments and outcomes during the COVID-19 pandemic in order to uncover the most effective maintenance protocols for cutaneous lymphomas and impact of treatment interruption. Data was collected retrospectively from nine international institutions, including 149 patients. Younger patients had earlier stages of disease and were most frequently treated with skin-directed therapies including topical steroids, mechlorethamine gel, and phototherapy. Treatment interruption varied by treatment type and stage, with patients on topical therapies and earlier stages of disease being least likely to experience interruption. Treatment interruption was significantly associated with progression of disease and worse outcomes, with twice as many patients progressing who had interruption compared to those without interruption. This study may demonstrate the significance of continuous maintenance therapies, even in younger patients with early stages of disease.
OBJECTIVE: the aim of this study is to report epidemiological data, clinical presentations and management of chronic immune thrombocytopenic purpura (ITP) in a single center in south of TUNISIA.
METHODS: retrospective study collecting all cases of chronic ITP among children aged less than 14 years, in a department of pediatrics in south of Tunisia during a period of 13 years (from 1st January 2010 to 31 December 2022) Results: during the study period, 72 newly diagnosed ITP were recorded; 11 patients evolves chronic ITP (12 ,5%). They were 6 boys and 5 girls. Two patients were aged more than 10 years at the onset of the disease. Symptoms in the chronic stage were mucocutaneous bleeding. One patient developed post traumatic cerebral hemorragia. Three patients had severe form, and required second-line therapy. Two patients requested Eltrombopag with good response. One patient had spontaneous recovery after 3 years of follow up.
CONCLUSION: Management of chronic ITP represents a real challenge for pediatrician. Currently, there are some recommendations and guidelines which can guide management strategy of severe forms of Chronic ITP.
Leaf rust is a widespread foliar wheat disease causing substantial yield losses worldwide. Slow rusting is "adult plant" resistance that significantly slows epidemic development and thereby reduces yield loss. Wheat accession CI 13227 was previously characterized as having slow-rusting resistance. To validate the quantitative trait loci (QTLs) and develop diagnostic markers for slow rusting resistance in CI 13227, a new population of recombinant inbred lines of CI 13227 × Everest was evaluated for latent period, final severity, area under the disease progress curve, and infection type in greenhouses and genotyped using genotyping-by-sequencing. Four QTLs were identified on chromosome arms 2BL, 2DS, 3BS, and 7BL, explaining 6.82 to 28.45% of the phenotypic variance for these traits. Seven kompetitive allele-specific polymorphism markers previously reported to be linked to the QTLs in two other CI 13227 populations were validated. In addition, the previously reported QLr.hwwg-7AL was remapped to 2BL (renamed QLr.hwwg-2BL) after adding new markers in this study. Phenotypic data showed that the recombinant inbred lines harboring two or three of the QTLs had a significantly longer latent period. QLr.hwwg-2DS on 2DS showed a major effect on all rust resistance traits and was finely mapped to a 2.7-Mb interval by two newly developed flanking markers from exome capture. Three disease-resistance genes and two transporter genes were identified as the putative candidates for QLr.hwwg-2DS. The validated QTLs can be used as slow-rusting resistance resources, and the markers developed in this study will be useful for marker-assisted selection.
A vision test device includes a hollow shell, a converging lens and a diverging lens. The converging lens is arranged in the hollow housing, and includes a converging focal length. The diverging lens is arranged in the hollow housing at intervals relative to the converging lens, and includes a diverging focal length. An optical axis of the diverging lens and the converging lens overlap each other, and the diverging focal length partially overlaps the converging focal length. The vision test device attaches optotypes displayed by a display 
device to one end of the hollow housing adjacent to the diverging lens. The diverging lens demagnifies the optotypes to form a first virtual image within the converging focal length. The converging lens magnifies the first virtual image to form a second virtual image for vision testing.
OBJECTIVE: Breaking has gained public attention as a form of sports activity. The associated intense movements of the hip joints are possibly linked to the development of femoroacetabular impingement (FAI). Therefore, this study aimed to assess clinical and radiographic FAI measures in professional breakers compared to hobby athletes.
METHODS: The study cohort consisted of professional breakers with persisting hip pain who were 1:1 matched to a cohort of FAI patients without professional sports careers from our outpatient clinic. The primary endpoint assessed on standardized plain radiographs was the alpha angle (AA). Further measures were the acetabular index (AI), lateral center-edge angle (LCEA), crossover sign, ischial spine sign, and femoral head extrusion index (FHEI). The modified Harris Hip Score (mHHS) and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score were used to obtain patient-reported measures.
RESULTS: We recruited ten professional breakers and matched them to ten hobby athletes. The median AA was significantly higher in the breakers compared with the hobby athletes (73° [IQR 66.5°, 84.2°]) vs. 61.8° [IQR 59.5°, 64.8°], p = 0.0004). There was a significant reduction in weekly training hours in breakers after diagnosis (13.0 hours [interquartile range [IQR] 9.5, 32.4] to 1.5 hours [IQR 0, 4.8], p = 0.0039). There were no inter-group differences regarding mHHS, WOMAC, and additional radiographic measurements.
CONCLUSION: Breakers have higher AA in cam-type FAI compared to nonprofessional athletes. The corresponding hip pain significantly reduced training hours and caused the end of their breaking career. The potentially high prevalence of FAI in breakers and the corresponding consequences need to be considered early when athletes present with hip pain.
BACKGROUND: Up to 20% of patients undergoing total knee arthroplasty (TKA) remain dissatisfied with their outcome, leading to the identification of risk factors for poor outcomes. The purpose of this study was to analyze the effect of chronic sleep disorders on patient-reported outcomes after primary TKA.
METHODS: A retrospective review of patients undergoing primary TKA was conducted using a prospectively collected database of patients from a single institution between 2018 and 2022. The cohort was split based on the presence of documented chronic sleep disorders, identified preoperatively from the electronic medical record using current procedural terminology codes. The sample was further restricted to include all patients who have sleep disorders (SDs), as well as a 3:1 propensity-matched (on age, sex, body mass index, and American Society of Anesthesiologists class) cohort of patients who had no documented SDs (NSDs) prior to surgery. The final sample included 172 patients (SD: 43; NSD: 129). Repeated-measures linear mixed model analysis was used to analyze the progression of Knee Injury and Osteoarthritis Outcome Score (KOOS) through time between groups.
RESULTS: Those who had SDs had a lower preoperative mean total KOOS score (40.2) than the NSD group (44.1); however, this was not significantly different (P = .108). At 1 year postoperatively, those who had an SD had a significantly higher mean total KOOS score (87.2) than the NSD group (80.4), P = .005. When comparing total KOOS scores by group, over each time period, the SD group showed a better progression when compared to the NSD group, P = .001.
CONCLUSIONS: Compared to patients who did not have documented chronic sleep disorders, patients who had a prior history of chronic sleep disorders reported significantly greater improvements in most KOOS domains in the 12-month period following TKA.
Tracheobronchial or esophageal fistula after aortic surgery has been reported sporadically in the literature, however, reports of an aortopulmonary fistula associated with a post-operative aortic pseudoaneurysm are rare. We experienced a case of refractory heart failure due to an aortopulmonary fistula associated with a post-operative aortic pseudoaneurysm. A 60-year-old man who had undergone aortic surgery 2 years earlier was hospitalized for congestive heart failure. He was diagnosed with refractory heart failure after 10 days of diuretic therapy failed to improve his condition. He underwent a contrast-enhanced computed tomography (CT) scan and was suspected to have pulmonary artery perforation of an aortic pseudoaneurysm at the anastomotic site of the ascending aortic surgery. Transesophageal echocardiography showed shunt blood flow from the aortic aneurysm into the right pulmonary artery, leading to a definitive diagnosis of aortopulmonary fistula with post-operative aortic pseudoaneurysm. Computed tomography angiography is commonly used to diagnose an aortic fistula; however, diagnosis is often difficult because of the subtle imaging findings. We highlight the usefulness of transesophageal echocardiography in providing a definitive diagnosis and detailed morphologic information on this pathophysiology.
Participants in this condition will receive 8 sessions of BA treatment over the course of approximately 8 weeks (one session per week). The sessions will be conducted in their homes using an Army approved secure web-based video conferencing system. BA has been successfully delivered in this time frame, and it has been delivered via in-home video conferencing technology.
Drug interaction studies have been completed with INVIRASE and saquinavir soft gel capsules. Observations from drug interaction studies with saquinavir soft gel capsules may not be predictive for INVIRASE/ritonavir. Because ritonavir is coadministered, prescribers should also refer to the prescribing information for ritonavir regarding drug interactions associated with this agent.

The metabolism of saquinavir is mediated by cytochrome P450, with the specific isoenzyme CYP3A4 responsible for 90% of the hepatic metabolism. Additionally, saquinavir is a substrate for P-Glycoprotein (Pgp). Therefore, drugs that affect CYP3A4 and/or Pgp, may modify the pharmacokinetics of saquinavir. Similarly, saquinavir might also modify the pharmacokinetics of other drugs that are substrates for CYP3A4 or Pgp.

Drugs that are contraindicated specifically due to the expected magnitude of interaction and potential for serious adverse events are listed in Table 4 under CONTRAINDICATIONS. These recommendations are based on either drug interaction studies or predicted interactions due to the expected magnitude of interaction and potential for serious events or loss of efficacy.

Drug interactions that have been established based on drug interaction studies are listed with the pharmacokinetic results in Table 2, which summarizes the effect of saquinavir, administered as saquinavir soft gel capsules or INVIRASE, on the geometric mean AUC and Cmax of coadministered drugs and Table 3, which summarizes the effect of coadministered drugs on the geometric mean AUC and Cmax of saquinavir. Clinical dose recommendations can be found in Table 5. The magnitude of the interactions may be different when INVIRASE is given with ritonavir (see CLINICAL PHARMACOLOGY).

When coadministering INVIRASE/ritonavir with any agent having a narrow therapeutic margin, such as anticoagulants, anticonvulsants, and antiarrhythmics, special attention is warranted. With some agents, the metabolism may be induced, resulting in decreased concentrations. Examples and clinical dose recommendations can be found in Table 5.
Brain-derived extracellular vesicles participate in interorgan communication after traumatic brain injury by transporting pathogens to initiate secondary injury. Inflammasome-related proteins encapsulated in brain-derived extracellular vesicles can cross the blood‒brain barrier to reach distal tissues. These proteins initiate inflammatory dysfunction, such as neurogenic heterotopic ossification. This recurrent condition is highly debilitating to patients because of its relatively unknown pathogenesis and the lack of effective prophylactic intervention strategies. Accordingly, a rat model of neurogenic heterotopic ossification induced by combined traumatic brain injury and achillotenotomy was developed to address these two issues. Histological examination of the injured tendon revealed the coexistence of ectopic calcification and fibroblast pyroptosis. The relationships among brain-derived extracellular vesicles, fibroblast pyroptosis and ectopic calcification were further investigated in vitro and in vivo. Intravenous injection of the pyroptosis inhibitor Ac-YVAD-cmk reversed the development of neurogenic heterotopic ossification in vivo. The present work highlights the role of brain-derived extracellular vesicles in the pathogenesis of neurogenic heterotopic ossification and offers a potential strategy for preventing neurogenic heterotopic ossification after traumatic brain injury. Brain-derived extracellular vesicles (BEVs) are released after traumatic brain injury. These BEVs contain pathogens and participate in interorgan communication to initiate secondary injury in distal tissues. After achillotenotomy, the phagocytosis of BEVs by fibroblasts induces pyroptosis, which is a highly inflammatory form of lytic programmed cell death, in the injured tendon. Fibroblast pyroptosis leads to an increase in calcium and phosphorus concentrations and creates a microenvironment that promotes osteogenesis. Intravenous injection of the pyroptosis inhibitor Ac-YVAD-cmk suppressed fibroblast pyroptosis and effectively prevented the onset of heterotopic ossification after neuronal injury. The use of a pyroptosis inhibitor represents a potential strategy for the treatment of neurogenic heterotopic ossification.
Patients with clinical signs and symptoms of uUTI who have a high probability of the required number of bacteria in their urine, measured by positive test for nitrite and /or leucocyte esterase by means of a dipstick will be enrolled in this study. Only these patients with bacterial count equal or more than 10e5 cfu/mL will be included in the efficacy analysis. At Baseline, patients will be randomly assigned (2:1) to receive Finafloxacin 300 mg or Ciprofloxacin 250 mg, following a double-dummy design, ie Group 1 will receive Finafloxacin tablets + Ciprofloxacin placebo capsule while Group II will receive Ciprofloxacin capsule + Finafloxacin placebo tablets. The treatment will last in total 3 days. The microbiological results will be compared with the baseline microbiology. If the concentration of initial pathogen in the urine is equal or more than 10e3 cfu/mL in the post-therapy culture compared with the baseline , this will define a bacteriological eradication. Microbiological assessment will be performed as well. Evaluation of the bacteria reinfection or relapse will be performed, based on the microbiology results. The status of clinical improvement and cure will be considered additionally.
Objective: To summarize the clinical features of epilepsy and (or) developmental delay associated with KCNB1 gene variants in children. Methods: A case series study was conducted on 24 children with KCNB1 gene variants associated with epilepsy and (or) developmental delay who were treated at the Children's Medical Center of Peking University First Hospital and the Department of Neurology of Shenzhen Children's Hospital from July 2015 to June 2024. The manifestations of seizures, electroencephalogram (EEG) and genetic test results of those children were analyzed. Results: All the KCNB1 gene variants were de novo, involving 20 different variation, including 15 missense variations, 3 frameshift variations and 2 nonsense variations. There were 7 novel variations. Among the 24 developmental and epileptic encephalopathy children, there were 14 boys and 10 girls. The last follow-up age ranged from 9 months to 13 years and 9 months. Seizures were present in 21 children (88%), with onset ranging from 1 month to 7 years, and 76% (16/21) began before 2 years of age. The seizure types included focal seizures in 15 children (71%), epileptic spasms, myoclonic seizures, and generalized tonic-clonic seizures in 6 children respectively, atypical absence seizures in 4 children, and myoclonic atonic seizures in 1 child. Seventeen children (81%) had a cluster of seizures and 5 had a history of focal status epilepticus with impaired consciousness. All 24 children had varying degrees of developmental delay, with 3 presenting solely developmental delay. EEG abnormalities were present in all the 21 children with seizures, including focal or multifocal discharges in 20 children, generalized discharges in 10 children, hypsarrhythmia in 2 children, and electrical status epilepticus during sleep in 3 children. Magnetic resonance imaging abnormalities were found in 5 of the 24 children. Among the 21 children with seizures, 57% (12/21) achieved seizure control. Conclusions: KCNB1 gene variants are predominantly de novo missense variation. Most affected children present with epilepsy, though some may exhibit only developmental delay. Epilepsy often begins before 2 years of age, with focal seizures being the most common type. About 80% of patients experience clustered seizures. Although most patients achieve seizure control, they still exhibit varying degrees of developmental delay, consistent with developmental epileptic encephalopathy.
This prospective study will include patients presenting for spinal surgery. There will be no change in the anesthetic or perioperative care of these patients. Per our usual clinical routine, cell saver will be used intraoperatively to limit the need for allogeneic blood. Tissue and cerebral oxygenation will be monitored using near infrared spectroscopy (NIRS). The device is applied non-invasively like pulse oximetry to a muscle bed (usually the deltoid) and the forehead to measure tissue oxygenation. These devices are used routinely in the operating room and the cardiothoracic intensive care unit. Although not used on every major orthopedic procedure, these devices are routinely used in various high risk clinical scenarios. As clinically indicated, cell saver blood (autologous) or allogeneic blood will be administered. During this time, tissue and cerebral oxygenation will be recorded every 5 minutes starting 10 minutes before the transfusion and continued for 30 minutes following the transfusion.
