Acute abdomen caused by spontaneous rupture of the inflammatory myofibroblastic tumor of the urinary bladder (IMTUB) is a rare clinical emergency of the urinary system.It is difficult to distinguish it from spontaneous rupture of bladder caused by other causes before surgery. An emergency case of spontaneous rupture of IMTUB was reported. A 57-year-old middle-aged woman was admitted to the hospital because of "acute lower abdominal pain for 5 hours". No history of smoking and gross hematuria. The physical examination revealed visible abdominal tenderness as well as signs of shock. A pelvic CT scan shows a space-occupying lesion above the bladder with massive accumulation of blood. When the nature of the tumor could not be determined, emergency laparotomy and partial cystectomy were performed, and postoperative pathology confirmed cystitis myofibroblastic tumor. No local recurrence or distant metastasis of the tumor was observed during the regular follow-up period of 6 months. IMTUB should focus on prevention and treatment, with a combination of preoperative examination and postoperative pathology, and finally implement highly individualized treatment.

Sickle cell disease (SCD) is a severe monogenic disease associated with high morbidity and mortality and a disproportionate burden on Black communities. Few population-based studies have examined the prevalence of comorbidities among persons with SCD. We estimated the prevalence of comorbidities experienced by individuals with SCD enrolled in employer-based health insurance plans in the US over their non-elderly lifetimes (0-64 years of age) with a retrospective cohort design using Truven Health MarketScan commercial claims data from 2007-2018. ICD-9/10 codes were used to identify individuals with SCD using a previously published algorithm. For this cohort, comorbidities associated with SCD were identified across 3 age categories (<18, 18-45, 46-64 years-old), based on the CMS Chronic Comorbidities Warehouse or SCD-specific diagnosis codes, when applicable. The total number of SCD patients available for analysis in each age category was 7,502 (<18 years), 10,183 (18-45 years) and 4,459 (46-64 years). Across all ages, vaso-occlusive pain, infections (non-specific), and fever were the most common comorbidities. Vaso-occlusive pain and infection were the most prevalent conditions for persons age <18- and 18-45-year-olds, while in the 46-54-year-old age group, infection and cardiovascular including pulmonary hypertension were most prevalent. Compared to persons <18 years old, the prevalence of vaso-occlusive pain, fever, and acute chest syndrome claims declined in older populations. The comorbidity burden of SCD is significant across all age groups. SCD patients experience comorbidities of age such as chronic pain, cardio-vascular conditions including pulmonary hypertension and renal disease at far higher rates than the general population. Novel disease modifying therapies in development have the potential to significantly reduce the comorbidity burden of SCD.

This study aimed to compare the analgesic effects of an injectable protocol using multimodal analgesia with or without opioids in cats undergoing ovariohysterectomy (OVH). Thirty-two healthy cats were enrolled in a prospective, blinded, randomized trial after the caregiver's written consent. Cats received a combination of ketamine (4 mg/kg), midazolam (0.25 mg/kg) and dexmedetomidine (40 μg/kg), and either buprenorphine (20 μg/kg) or saline (same volume as buprenorphine) intramuscularly [opioid-sparing (OSA) and opioid-free anesthesia (OFA) groups, respectively]. Intraperitoneal bupivacaine 0.25% (2 mg/kg) and meloxicam (0.2 mg/kg subcutaneously) were administered before OVH. Atipamezole (400 μg/kg intramuscularly) was administered at the end of surgery. Pain and sedation were evaluated using the Feline Grimace Scale (FGS) and a dynamic interactive visual analog scale, respectively. Intravenous buprenorphine was administered as rescue analgesia if FGS scores ≥ 0.39/1. Statistical analysis included repeated measures linear mixed models, Fisher's exact test and Bonferroni adjustments when appropriate ( < 0.05). Twenty-seven cats were included. The prevalence of rescue analgesia was lower in OSA ( = 0/13) than in OFA ( = 5/14) ( = 0.04). The FGS scores (least square means and 95% CI) were higher in OFA at 1 [2.0 (1.3-2.7)] and 2 h [2.2 (1.5-2.9)] than baseline [0.7 (0.0-1.4)], but not in OSA. Sedation scores were not significantly different between groups. Opioid-free injectable anesthesia was appropriate for some cats using a multimodal approach. However, a single dose of intramuscular buprenorphine eliminated the need for rescue analgesia and assured adequate pain management after OVH in cats.

Gulf War Illness (GWI) is a chronic illness that affects upward of 32% of deployed Veterans to the 1991 Gulf War (GW). The symptoms are medically unexplained, ranging across cognitive deficits, fatigue, gastrointestinal problems, and musculoskeletal pain. Research indicates that chemical warfare agents play a key role in the onset and progression of GWI. The Khamisiyah ammunition storage that housed chemical warfare agents such as sarin, an acetylcholinesterase (AChE) inhibitor, was demolished during the GW, releasing toxicants into the atmosphere affecting deployed troops. Exposure to other chemical agents such as pyridostigmine bromide, N,N-diethyl-m-toluamide, permethrin and chlorpyrifos, were also prevalent during the war. These additional chemical agents have also been shown to inhibit AChE. AChE inhibition induces an acetylcholine build-up, disrupting signals between nerves and muscles, which in high doses leads to asphyxiation. Little is known about low dose exposure. As bioactive compounds tend to interact with multiple proteins with various physiological effect, we aimed to identify other potential shared targets to understand the extent in which these chemicals could lead to GWI. We followed a reverse screening approach where each chemical is computationally docked to a library of protein targets. The programs PharmMapper and TargetNet were used for this purpose, and further analyses were conducted to mark significant changes in participants with GWI. Previously published work on DNA methylation status in GWI was reanalyzed focusing specifically on the predicted shared targets indicating significant changes in DNA methylation of the associated genes. Our findings thus suggest that exposure to GWI-related agents may converge on similar targets with roles in inflammation, neurotransmitter and lipid metabolism, and detoxification which may have impacts on neurodegenerative-like disease and oxidative stress in Veterans with GWI.

With emergent Sars-Cov-2, a highly transmissive virus that caused millions of deaths worldwide, the development of vaccines became urgent to combat COVID-19. Although rare, important adverse effects had been described in a hypothetical scenario of immune system overstimulation or overreaction. Still's disease is a rare inflammatory syndrome of unknown etiology. It manifests as a cytokine storm, mainly IL-18 and IL-1β, and presents itself with fever spikes, joint pain, maculopapular evanescent salmon-pink skin rash, and sore throat, among other symptoms. Here, we report a case of a 44-year-old healthy male who developed adult-onset Still's disease (AOSD) with atypical symptoms after both doses of ChAdOx1 nCoV-19 vaccine with 3 months of dose interval. The medical team suspected Still's disease and started prednisone 1 mg/kg (40mg). The next day the patient showed a marked improvement in articular and chest pains and had no other fever episodes. Therefore, he was discharged to continue the treatment in outpatient care. On the six-month follow-up, the patient was free of complaints, and the progressive corticoid withdrawal plan was already finished.

Fruit pomace addition to lucerne silage could rapidly reduce silage pH creating an acidic environment and thus maybe preventing spoilage. However, the purpose of this study was to investigate the effect of different rates of inclusion of citrus lemon by-products on lucerne. In this study, the following five different treatments were prepared: L0 (control) with 100% lucerne; L25 (75% lucerne with 25% lemon pomace); L50 (50% lucerne with 50% lemon pomace); L75 (25% lucerne with 75% lemon pomace); and L100 (100% lemon pomace). After ensiling, the chemical composition, nutritive value, stability, apparent digestibility, and gas production of silage were determined. The dry matter (DM) content was higher for lemon pomace substitution equal to or exceeded 50% ( < 0.01). Crude protein, on the contrary, decreased ( < 0.01) over the same percentage of substitution. The L100 and L75 treatments showed higher DM apparent disappearance rate and lower ( < 0.05) crude protein and neutral detergent fiber apparent degradation rate . L0. Lemon pomace could be used at high inclusion level in lucerne silage, allowing the preservation of this by-product all the year, improving some chemical silage characteristics, and reducing proteolytic processes that usually happen on lucerne silage. Moreover, the apparent digestibility and gas production results showed that a partial substitution of lucerne with lemon pomace is able to improve silage digestibility.

Fatigue and muscle weakness are common complaints in COVID-19 survivors. However, little is still known about the skeletal muscle qualitative and quantitative characteristics after hospitalization due to moderate and severe COVID-19.

Migraineurs are often plagued by sleep disorders. The university student population is high in number and is more vulnerable to migraines. However, no study has analyzed the sleep quality of students with migraine and related contributing factors. We used the Pittsburgh Sleep Quality Index (PSQI) scale to assess the sleep of migraine patients among college students and to explore the influencing factors of sleep quality. We performed primary screening for migraine using the ID-migraine screening, and further assessed headache characteristics, sleep, anxiety, depression, and mobile phone addiction in college students with positive primary screening, then diagnosed migraine according to the third edition of (ICHD-3). Finally, we analyzed the factors influencing sleep quality using Binary Logistic Regression Analysis. Those with scores greater than 5 points on the PSQI scale were believed to have poor sleep quality. The prevalence of migraine was 6.6%. A total of 545 migraineurs were eventually included in the analysis, the incidence of poor sleep quality was 64.04%. The three factors of experiencing aura (OR = 2.966, 95%CI = 1.756-5.010, < 0.05), anxiety (OR = 2.778, 95%CI = 1.434-5.382, < 0.05), and high Mobile phone addiction index (MPAI) score (OR = 1.025, 95%CI = 1.002-1.049, < 0.05) contributed enormously to poor sleep quality. Moreover, the factors of aura symptoms (OR = 3.796, 95%CI = 2.041-7.058, < 0.05), anxiety (OR = 3.146, 95%CI = 1.473-6.719, < 0.05), and MPAI score (OR = 1.028, 95%CI = 1.002-1.054, < 0.05) influenced the sleep quality of female migraineurs rather than male migraineurs. The incidence of poor sleep quality is high among university students with migraine. Aura symptoms, anxiety, and high MPAI score influence the sleep quality of migraineurs, especially females. The proposal of prevention and intervention measures is of great importance to the physical and mental health of students with migraine. identifier ChiCTR1800014343.

Omental infarction is a rare but a sinister cause of acute abdomen. Preoperative diagnosis is challenging due to its rare nature. It poses nonspecific abdominal signs that can be easily mistaken with other more common intra-abdominal pathologies. We report a case of a 37-year-old male patient presented with right lower quadrant abdominal pain with an elevation of inflammatory markers. His cross-sectional imaging did not a reveal specific diagnosis; therefore, a diagnostic laparoscopy was performed which revealed a non-inflamed appendix and an inflammatory mass formed by the ischemic omentum attached to the ascending colon. Diagnostic laparoscopy and subsequent laparotomy revealed spontaneous omental infarction. The histology of the resected specimen was in keeping with the omental necrosis. This case reflects the importance of considering omental infarction in patients presenting with abdominal pain and raised inflammatory markers. He made an uneventful recovery following surgery.

Primary intraosseous meningiomas (PIOMs) are a rare subset of meningiomas, comprising fewer than 1% of all such tumors. Furthermore, PIOMs presenting as osteogenic lesions that invade both the dura and subcutaneous tissue are extremely rare. Unlike intracranial meningiomas, diagnosing and treating PIOMs are challenges due to their insidious clinical behavior and a lack of clear radiological diagnostic criteria. We report the case of a 60-year-old female with headache and a slightly outward protrusion of the parietal region of the skull. CT showed an osteogenic lesion in the right parietal bone. MR imaging indicated mild to moderate homogeneous enhancement with an intense dural reaction. The suggested clinical diagnosis was lymphoma, so we performed a skull biopsy, which revealed an intraosseous benign meningioma. A precise resection strategy was planned with a neuronavigation system accompanied by a one-step customized titanium mesh cranioplasty. The lesion was completely removed, and pathological analysis confirmed a meningothelial meningioma (WHO Grade I) of intraosseous layer origin invading the dura mater and subcutaneous tissue. This case highlights the need for an initial biopsy when the lesion is difficult to diagnose on imaging. Complete resection should be attempted to minimize the risk of recurrence.
