Clinical Characteristics and Patterns of Immune Responses in COVID-19 Patients From a Rural Community Hospital.

Background Although demographic and clinical factors such as age, certain comorbidities, and sex have been associated with COVID-19 outcomes, these studies were largely conducted in urban populations affiliated with large academic medical centers. There have been very few studies focusing on rural populations that also characterize broader changes in inflammatory cytokines and chemokines. Methodology A single-center study was conducted between June 2020 and March 2021 in Abilene, Texas, USA. Patients were included if they presented to the hospital for treatment of COVID-19, had extra biological materials from routine care available, and were between the ages of 0 to 110 years. There were no exclusion criteria. Patient characteristics, symptom presentation, and clinical laboratory results were extracted from electronic health records. Blood specimens were analyzed by protein microarray to quantitate 40 immunological biomarkers. Results A total of 122 patients were enrolled, of whom 81 (66%) were admitted to the general non-critical inpatient unit, 37 (30%) were admitted to the intensive or critical care units, and four (3.2%) were treated outpatient. Most hospitalized COVID-19 patients in this rural population were elderly, male, obese, and retired individuals. Predominant symptoms for non-critical patients were shortness of breath, fever, and fatigue. Ferritin levels for outpatient patients were lower on average than those in an inpatient setting and lactate dehydrogenase (LDH) levels were noted to be lower in non-critical and outpatient than those in the intensive care unit setting. Inflammatory biomarkers were positively correlated and consistent with inflammatory cascade. Interleukin (IL)-10 was positively correlated while platelet-derived growth factor was negatively correlated with inflammatory biomarkers. Patients ≥65 years had significantly higher levels of LDH and seven cytokines/chemokines (granulocyte-macrophage colony-stimulating factor (GM-CSF), interleukin IL-1b, IL-6, IL-10, IL-11, macrophage inflammatory protein (MIP)-1d, and IL-8) while levels of five other immune molecules (intercellular adhesion molecule 1 (ICAM-1), monocyte chemoattractant protein 1 (MCP-1), tissue inhibitor of metalloproteinase 2 (TIMP-2), IL-2, and IL-4) were significantly lower compared to those <65 years. Females had significantly higher levels of LDH and 10 cytokines/chemokines (GM-CSF, IL-1b, IL-6, IL-10, IL-11, IL-15, IL-16, MIP-1a, MIP-1d, and IL-8) while levels of TIMP-2 and IL-4 were significantly lower than male patients. Conclusions The clinical characteristics of this rural cohort of hospitalized patients differed somewhat from nationally reported data. The contributions of social, environmental, and healthcare access factors should be investigated. We identified age and sex-associated differences in immunological response markers that warrant further investigation to identify the underlying molecular mechanisms and impact on COVID-19 pathogenesis.

Alocasia odora poisoning due to calcium oxalate needle crystals in Japan.

Objective: To elucidate the actual circumstances of damage caused by Japanese Alocasia (A) odora. Materials and Methods: We investigated cases in Japan from our own hospital in the eastern part of Shizuoka Prefecture as well as published reports. Results: A. dorais found in western Japan, and plants of the Alocasia genus are cultivated often. A. odora is frequently associated with food poisoning because its aboveground parts resemble those of Satoimo (Colocasia esculenta). Moreover, A. odora contains insoluble calcium oxalate crystals, which cause poisoning symptoms, such as oral pain, nausea, vomiting, and laryngeal edema, resulting in near asphyxia, diarrhea following shock, and skin dermatitis. Calcium oxalate crystals are abundant in Araceae family plants, and cases of health damage owing to the accidental ingestion of Araceae plants have been reported worldwide. Conclusion: Due to the strong irritation felt in the mouth upon contact with the plant, it is advisable to immediately spit out the plant and rinse the mouth. In addition to drug administration, ensuring a secure airway may be necessary if there is a risk of asphyxiation.

Detection of influenza A(H3N2) viruses with polymerase acidic subunit substitutions after and prior to baloxavir marboxil treatment during the 2022-2023 influenza season in Japan.

Baloxavir marboxil (baloxavir), approved as an anti-influenza drug in Japan in March 2018, can induce reduced therapeutic effectiveness due to PA protein substitutions. We assessed PA substitutions in clinical samples from influenza-infected children and adults pre- and post-baloxavir treatment, examining their impact on fever and symptom duration. During the 2022-2023 influenza season, the predominant circulating influenza subtype detected by cycling-probe RT-PCR was A(H3N2) (n = 234), with a minor circulation of A(H1N1)pdm09 (n = 10). Of the 234 influenza A(H3N2) viruses collected prior to baloxavir treatment, 2 (0.8%) viruses carry PA/I38T substitution. One virus was collected from a toddler and one from an adult, indicating the presence of viruses with reduced susceptibility to baloxavir, without prior exposure to the drug. Of the 54 paired influenza A(H3N2) viruses collected following baloxavir treatment, 8 (14.8%) viruses carried E23 K/G, or I38 M/T substitutions in PA. Variant calling through next-generation sequencing (NGS) showed varying proportions (6-100 %), a polymorphism and a mixture of PA/E23 K/G, and I38 M/T substitutions in the clinical samples. These eight viruses were obtained from children aged 7-14 years, with a median fever duration of 16.7 h and a median symptom duration of 93.7 h, which were similar to those of the wild type. However, the delayed viral clearance associated with the emergence of PA substitutions was observed. No substitutions conferring resistance to neuraminidase inhibitors were detected in 37 paired samples collected before and following oseltamivir treatment. These findings underscore the need for ongoing antiviral surveillance, informing public health strategies and clinical antiviral recommendations for seasonal influenza.

Clinical and patient-reported outcomes and neurofilament response during tofersen treatment in SOD1-related ALS-A multicenter observational study over 18 months.

INTRODUCTION/AIMS: In amyotrophic lateral sclerosis (ALS) caused by SOD1 mutations (SOD1-ALS), tofersen received accelerated approval in the United States and is available via expanded access programs (EAP) outside the United States. This multicenter study investigates clinical and patient-reported outcomes (PRO) and serum neurofilament light chain (sNfL) during tofersen treatment in an EAP in Germany. METHODS: Sixteen SOD1-ALS patients receiving tofersen for at least 6 months were analyzed. The ALS progression rate (ALS-PR), as measured by the monthly change of the ALS functional rating scale-revised (ALSFRS-R), slow vital capacity (SVC), and sNfL were investigated. PRO included the Measure Yourself Medical Outcome Profile (MYMOP2), Treatment Satisfaction Questionnaire for Medication (TSQM-9), and Net Promoter Score (NPS). RESULTS: Mean tofersen treatment was 11 months (6-18 months). ALS-PR showed a mean change of -0.2 (range 0 to -1.1) and relative reduction by 25%. Seven patients demonstrated increased ALSFRS-R. SVC was stable (mean 88%, range -15% to +28%). sNfL decreased in all patients except one heterozygous D91A-SOD1 mutation carrier (mean change of sNfL -58%, range -91 to +27%, p < .01). MYMOP2 indicated improved symptom severity (n = 10) or yet perception of partial response (n = 6). TSQM-9 showed high global treatment satisfaction (mean 83, SD 16) although the convenience of drug administration was modest (mean 50, SD 27). NPS revealed a very high recommendation rate for tofersen (NPS +80). DISCUSSION: Data from this EAP supported the clinical and sNfL response to tofersen in SOD1-ALS. PRO suggested a favorable patient perception of tofersen treatment in clinical practice.

Etiological differences in demographics, clinical course and consequences of acute pancreatitis: a retrospective study.

OBJECTIVE: Aim: The study is intended to consider acute pancreatitis from the point of view of its etiological structure, as well as demographic description, features of the clinical course, distribution of morphological forms, severity and consequences of the disease in different etiological variants. PATIENTS AND METHODS: Materials and Methods: The work was based on a retrospective analysis of the medical records of 677 patients with acute pancreatitis who underwent inpatient treatment from 2017 to 2022 in an emergency hospital and a tertiary regional hospital in Vinnytsia, Ukraine. RESULTS: Results: The etiological structure of the general sample was as follows: the alimentary factors - 37,5% of cases, biliary - 18,6%, alcohol - 14,0% and postoperative - 7,8%, respectively. The oldest patients were observed in the group with biliary AP (age [median, interquartile range] 61 [46-72] years), the youngest - in the group with alcoholic AP (age [median, interquartile range] 40 [35-47] years). Men significantly predominated in the groups with alimentary and alcoholic AP. A significant predominance of women was observed in the group with biliary AP (62,7% vs. 37,3%, p=0,0003). The highest mortality was in the alcoholic AP group (22,1%), also here was a significantly lower rate of inpatient bed days (6,0). Edematous AP was dominant in all etiological variants. While infected necrotic pancreatitis was significantly more often found in patients with alcoholic genesis (7,4%). CONCLUSION: Conclusions: The etiologic variations of acute pancreatitis differ by demographic and clinical indicators and require more detailed study to understand its prognosis, management, and development of effective prevention and treatment strategies.

Comparative evaluation of disease dynamics in wild boar and domestic pigs experimentally inoculated intranasally with the European highly virulent African swine fever virus genotype II strain "Armenia 2007".

Since the reintroduction of African swine fever virus (ASFV) in Europe in 2007 and its subsequent spread to Asia, wild boar has played a crucial role in maintaining and disseminating the virus. There are significant gaps in the knowledge regarding infection dynamics and disease pathogenesis in domestic pigs and wild boar, particularly at the early infection stage. We aimed to compare domestic pigs and wild boar infected intranasally to mimic natural infection with one of the original highly virulent genotype II ASFV isolates (Armenia 2007). The study involved euthanising three domestic pigs and three wild boar on days 1, 2, 3, and 5 post-infection, while four domestic pigs and four wild boar were monitored until they reached a humane endpoint. The parameters assessed included clinical signs, macroscopic lesions, viremia levels, tissue viral load, and virus shedding in nasal and rectal swabs from day 1 post-infection. Compared with domestic pigs, wild boar were more susceptible to ASFV, with a shorter incubation period and earlier onset of clinical signs. While wild boar reached a humane endpoint earlier than domestic pigs did, the macroscopic lesions were comparatively less severe. In addition, wild boar had earlier viremia, and the virus was also detected earlier in tissues. The medial retropharyngeal lymph nodes were identified as key portals for ASFV infection in both subspecies. No viral genome was detected in nasal or rectal swabs until shortly before reaching the humane endpoint in both domestic pigs and wild boar, suggesting limited virus shedding in acute infections.

Clinical course of psoriatic arthritis treated with biologics delineated with ultrasonography.

Psoriatic arthritis (PsA) is a chronic, inflammatory articular disease regarded as a specific subtype of psoriasis. Long-term assessment for PsA using ultrasonography has not yet been investigated. The present study was conducted to delineate the changes in articular lesions after the initiation of biologics using ultrasonography, and to provide the evidence of the utility of ultrasonography in long-term follow-up of PsA patients. We retrospectively recruited 17 Japanese PsA patients treated with biologics who met the classification criteria for psoriatic arthritis. Ultrasonographic images were recorded using a high-frequency linear 18 MHz probe through Doppler- and B-modes. Before the treatment with biologics, all examined patients (100%) had enthesitis and extensor tendinitis, while only six patients (35.3%) had loss of the fibrillar pattern of the tendon (LFP). There were significant changes over time in the numerical rating scale score for pain, and in the degree of ultrasonographic findings, including enthesitis, extensor tendinitis, and LFP. Also, there were significant changes over time between these ultrasonographic findings. The study identified the improvement course for a specific PsA lesion after the initiation of biologics. The improvement courses in enthesitis, extensor tendinitis, and LFP were found to differ from each other. These results may contribute to deeper understanding of the pathogenesis of PsA.

Prevalence and clinical profiles of primary sclerosing cholangitis in China: Data from electronic medical records and systematic literature retrieval.

BACKGROUND & AIMS: Epidemiology of primary sclerosing cholangitis (PSC) is lacking in China. We aimed to estimate the period prevalence and depict the clinical features of PSC in China. METHODS: We identified and included PSC cases between 2000 and 2023 from two sources: electronic medical records (EMR) and systematical literature retrieval (SLR). The period prevalence of PSC was estimated by the multiplier method. Rate ratios (RRs) for PSC prevalence in relation to macroeconomic indicators were calculated by the negative binomial regression model. RESULTS: A total of 1358 PSC cases were retrieved from 299 hospitals (162 from EMR and 1196 from SLR). Males accounted for 55.7 % of the PSC cases and 25.7 % had concomitant inflammatory bowel disease (IBD). The estimated period prevalence of PSC from 2000 to 2023 was 2.36 (95 % CI: 1.82, 3.34) per 100,000. Males had a numerically higher PSC prevalence than females (2.56, 95 % CI: 1.97, 3.63 vs. 2.14, 95 % CI: 1.65, 3.04 per 100,000). The highest prevalence of PSC was in East China at 4.87 (95 % CI: 3.44, 7.18) per 100,000, followed by North China at 2.94 (95 % CI: 2.33, 3.74) per 100,000, and the lowest in South China at 0.92 (95 % CI: 0.66, 1.30) per 100,000. Regional per capita GDP (RR 1.65, 95 % CI: 1.03, 2.65) and healthcare expenditure (RR 1.94, 95 % CI: 1.13, 3.38) were identified to be associated with PSC prevalence. CONCLUSION: Our study showed the estimated PSC prevalence varied within China, but was generally lower than that in Western countries.

A decade with anomic primary progressive aphasia.

Some patients with primary progressive aphasia (PPA) demonstrate only anomia. The lack of longitudinal observations of anomic PPA precluded us from determining whether progressive anomic aphasia was simply an early stage of semantic or logopenic variants, or a relatively independent variant. Herein, we report the 10-year clinical course of a patient with PPA who presented with pure anomic aphasia for 9 years. He is a right-handed man with anomia, who noticed word-finding difficulty at age 73. He was admitted to the hospital at age 77. On admission, the patient showed pure anomic aphasia with preserved other language function. Episodic memory and visuospatial function were preserved. Magnetic resonance imaging (MRI) revealed left temporal lobe atrophy. At 82 years of age, the patient presented with pure anomic aphasia. At 83 years old, he showed mild impairment in word comprehension and semantic memory, in addition to anomia. MRI demonstrated further atrophy in the bilateral anterior temporal lobes, predominantly on the left side. This case suggests the possibility of slowly progressive, late-onset anomic PPA, which could be differentiated from the early stage of semantic or logopenic variants.

Sex-Related Differences in the Phenotype and Course of Inflammatory Bowel Disease: SEXEII Study of ENEIDA.

BACKGROUND & AIMS: The impact of patient sex on the presentation of inflammatory bowel disease (IBD) has been poorly evaluated. Our aims were to assess potential disparities in IBD phenotype and progression between sexes. METHODS: We performed an observational multicenter study that included patients with Crohn's disease (CD) or ulcerative colitis from the Spanish ENEIDA registry. Data extraction was conducted in July 2021. RESULTS: A total of 51,595 patients with IBD were included, 52% were males and 25,947 had CD. The median follow-up period after diagnosis was 9 years in males and 10 years in females. In CD, female sex was an independent risk factor for medium disease onset (age, 17-40 y) (relative risk ratio, 1.45; 95% CI, 1.31-1.62), later disease onset (age, >40 y) (relative risk ratio, 1.55; 95% CI, 1.38-1.73), exclusive colonic involvement (odds ratio, 1.24; 95% CI, 1.14-1.34), inflammatory behavior (odds ratio, 1.14; 95% CI, 1.07-1.21), and extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.38-1.59). However, female sex was a protective factor for upper gastrointestinal involvement (odds ratio, 0.84; 95% CI, 0.79-0.90), penetrating behavior (odds ratio, 0.76; 95% CI, 0.70-0.82), perianal disease (odds ratio, 0.77; 95% CI, 0.71-0.82), and complications (odds ratio, 0.73; 95% CI, 0.66-0.80). In ulcerative colitis, female sex was an independent risk factor for extraintestinal manifestations (odds ratio, 1.48; 95% CI, 1.26-1.61). However, female sex was an independent protective factor for disease onset from age 40 onward (relative risk ratio, 0.76; 95% CI, 0.66-0.87), left-sided colonic involvement (relative risk ratio, 0.72; 95% CI, 0.67-0.78), extensive colonic involvement (relative risk ratio, 0.59; 95% CI, 0.55-0.64), and abdominal surgery (odds ratio, 0.78; 95% CI, 0.69-0.88). CONCLUSIONS: There is sexual dimorphism in IBD. The patient's sex should be taken into account in the clinical management of the disease.

Features of the clinical course of Autoimmune Encephalitis Associated with various antibodies.

Despite the increasing incidence of autoimmune encephalitis and the incomplete recovery observed in patients post-affliction, the issue of timely diagnosis remains unresolved. The primary objective of this study is identification the distinctive clinical presentation features evaluation the management strategies, and assess the outcomes of the disease in patients with various forms of autoimmune encephalitis. The research aims to contribute in a better understanding of the disease progression and facilitate the selection of optimal therapeutic interventions. A retrospective observational study enrolled 68 patients aged 18 years and older with verified autoimmune encephalitis who underwent treatment in state hospitals in Sofia, Bulgaria, from the beginning of 2014 to the end of 2022. The number of patients with pathology linked to antibodies against glycine receptors (Gly-R) was half as much, with 32 and 17 patients, respectively. The primary manifestations of autoimmune encephalitis included cognitive impairments observed in 51 patients, seizures occurring in 44 patients, and mood disorders observed in 22 patients. While the findings of imaging studies were nonspecific, hospitalizations for patients with this pathology, especially those with antibodies to CASPR2 and DPPX, were prolonged (114 and 232 days, respectively). In the vast majority of cases, incomplete recovery with residual symptoms was noted. Among the diverse forms of autoimmune encephalitis, the most prevalent is NMDA-R. Cognitive impairments predominate in the autoimmune encephalitis clinical presentation. Prolonged hospitalization periods and incomplete recovery of patients are characteristic features of autoimmune encephalitis, despite combined therapy involving intravenous administration of methylprednisolone and immunoglobulins.

A case study on anthrax in an eight-month old infant at Kyrgyz Republic.

Anthrax remains a threat, especially in countries like Kyrgyzstan with developed livestock farming. Despite preventive efforts, sporadic outbreaks endure on an annual basis, transmitted from infected animals to humans. Here, we report a severe anthrax case in an 8-month-old child known to be caused when a sick calf was slaughtered in the neighborhood without proper protocols, resulting in intra-family infection. This underscores the importance of swift diagnosis, treatment, preventive measures, and awareness of zoonotic infections, animal vaccination and adherence to sanitary and veterinary protocols.

Prior Appendectomy Is Associated With a Milder Clinical Course in Crohn's Disease: A Nationwide Population-based Cohort Study.

BACKGROUND: Appendectomy may affect the clinical course of Crohn's disease (CD), but rigorous evidence is sparse and contradicting. The aim of this study was to examine the association between appendectomy and the clinical course of CD. METHODS: All patients diagnosed with CD in Denmark in the period from 1977 to 2017 were identified from the Danish National Patient Registry. Patients with appendectomy were matched with up to 10 comparators with CD and no appendectomy; and rates of CD-related hospital admissions were compared between CD patients with and without appendectomy using incidence rate ratios (IRRs). We used stratified Cox regression analysis to calculate adjusted hazard ratios (aHRs) of initiating treatment with biologics or undergoing intestinal resections. RESULTS: In all, 21 189 CD patients (1936 with appendectomy and 19 253 without) were identified and followed for a median of 13.6 years. Crohn's disease patients who had undergone appendectomy experienced a lower rate of CD-related hospital admissions (appendectomy before CD: IRR = 0.83; 95% confidence interval [CI], 0.81-0.85; appendectomy after CD: IRR = 0.85; 95% CI, 0.81-0.88) compared with CD patients without appendectomy. For patients with appendectomy before CD diagnosis, the rate of initiating biologics was lower compared with CD patients with no appendectomy (aHR1-<5 years = 0.61; 95% CI, 0.46-0.81; aHR5-<10 years 0.47; 95% CI, 0.33-0.66; aHR10-20 years = 0.61; 95% CI, 0.47-0.79), as was the risk of undergoing colorectal resections (aHR1-<5 years = 0.94; 95% CI, 0.77-1.15; aHR5-<10 years 0.63; 95% CI, 0.47-0.85; aHR10-20 years = 0.75; 95% CI, 0.54-1.04). Rates of small bowel resections were comparable for CD patients with or without appendectomy prior to CD. Appendectomy performed after CD did not influence the rate of initiating treatment with biologics or undergoing intestinal resections. CONCLUSION: The clinical course of CD is milder for those who have previously undergone appendectomy.

In a large nationwide cohort study, patients with Crohn's disease who underwent appendectomy had a milder clinical course than those without appendectomy.

Usefulness of the Phalen Test and the Tinel Sign in the Prognosis and the Impact on Quality of Life of Patients with Carpal Tunnel Syndrome Undergoing Classical Open Carpal Tunnel Release.

Objective: To evaluate the usefulness of the Phalen test and the Tinel sign in the prognosis and the impact on quality of life in the clinical course of patients with carpal tunnel syndrome undergoing surgical treatment through the traditional open approach. Methods: The present is a cohort study on prognosis. We included 115 patients with high probability of receiving a clinical diagnosis of carpal tunnel syndrome with indication for surgical treatment. All patients underwent the Phalen test and Tinel sign and answered the Boston Carpal Tunnel Questionnaire before and after the surgical treatment. Results: The estimates for the probability of the time until remission of the Phalen test at 2, 4 and 16 weeks postoperatively were of 3.54% (95% confidence interval [95%CI]: 1.16%-8.17%), 0.88% (95%CI: 0.08%-4.38%) and 0.88% (95%CI: 0.08% to 4.38%) respectively, and, for the Tinel sign, they were of 12.39% (95%CI: 7.13%-19.18% ), 4.42% (95%CI : 1.65%-9.36%) and 2.65% (95%CI : 0.70%-6.94%) respectively. There was a reduction in the postoperative score on the Boston Carpal Tunnel Questionnaire of 1.8 points for symptom severity ( p < 0.001) and of 1.6 points for functional status ( p < 0.001). Conclusion: Phalen test remission was earlier than that of the Tinel sign, but, when performed as of the second postoperative week, they were prognostic factors favorable to the clinical course, with improved quality of life.

Exploring the Interplay between Complex Post-Traumatic Stress Disorder and Obsessive-Compulsive Disorder Severity: Implications for Clinical Practice.

Background and Objectives: Traumatic events adversely affect the clinical course of obsessive-compulsive disorder (OCD). Our study explores the correlation between prolonged interpersonal trauma and the severity of symptoms related to OCD and anxiety disorders. Materials and Methods: The study follows a cross-sectional and observational design, employing the International Trauma Questionnaire (ITQ) to examine areas linked to interpersonal trauma, the Hamilton Anxiety Rating Scale (HAM-A), and the Yale-Brown Obsessive-Compulsive Scale (Y-BOCS) to assess anxious and obsessive-compulsive symptoms, respectively. Descriptive analysis, analysis of variance (ANOVA), and logistic regression analyses were conducted. Results: We recruited 107 OCD-diagnosed patients, categorizing them into subgroups based on the presence or absence of complex post-traumatic stress disorder (cPTSD). The ANOVA revealed statistically significant differences between the two groups in the onset age of OCD (p = 0.083), psychiatric familial history (p = 0.023), HAM-A, and Y-BOCS (p < 0.0001). Logistic regression indicated a statistically significant association between the presence of cPTSD and Y-BOCS scores (p < 0.0001). Conclusions: The coexistence of cPTSD in OCD exacerbates obsessive-compulsive symptoms and increases the burden of anxiety. Further advancements in this field are crucial for mitigating the impact of early trauma on the trajectory of OCD and associated anxious symptoms.

Multisystemic Inflammation Influences Prognosis in Fulminant Lymphocytic Myocarditis.

BACKGROUND: Multisystem inflammatory syndrome (MIS) is a hyperinflammatory shock associated with cardiac dysfunction and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. However, there are no reports on using MIS criteria, such as multisystemic inflammation (MSI) in fulminant myocarditis, without SARS-CoV-2 infection. This study investigated the differences in clinical characteristics and course between patients with fulminant lymphocytic myocarditis (FLM) plus MSI and those without MSI.Methods and Results: This multicenter retrospective cohort study included 273 patients with FLM registered in the JROAD-DPC database between April 2014 and March 2017. We evaluated the presence of MSI using criteria modified from previously reported MIS criteria and compared the characteristics and risk of mortality or heart transplantation between FLM patients with MSI and without MSI. Of the 273 patients with FLM, 107 (39%) were diagnosed with MSI. The MSI group was younger (44 vs. 57 years; P<0.0001) and had more females (50% vs. 36%; P=0.0236), a higher incidence of pericardial effusion (58% vs. 40%; P=0.0073), and a lower 90-day mortality rate (19% vs. 33%; P=0.0185) than the non-MSI group. The risk of mortality at 90 days was lower in FLM patients aged <50 years with MSI aged <50 years than in those without MSI (P=0.0463). CONCLUSIONS: These results suggest that MSI may influence the prognosis of FLM, especially in patients aged <50 years.

Prevalence and Clinical Impact of Immune-Mediated Inflammatory Diseases in Patients with Inflammatory Bowel Disease: Results from a Large Retrospective Observational Study.

(1) Background: Inflammatory bowel diseases (IBDs) are chronic inflammatory disorders involving innate and adaptive immune responses. Despite primarily affecting the gut, recent insights highlight systemic implications, expanding our understanding beyond intestinal boundaries. (2) Methods: This retrospective multicentric study explored the association of IBD and immune-mediated inflammatory diseases (IMIDs) and the impact of concurrent IMIDs on the course of IBD. Clinical data were collected from consecutive medical records of patients with IBD. For assessing the impact of concurrent IMIDs, a control group of IBD patients without associated IMIDs was considered. (3) Results: Of 6589 IBD patients, 6.8% exhibited concomitant IMIDs. Notably, 79.8% of these patients had an aggressive disease course. Psoriasis, atopic dermatitis, and type 1 diabetes mellitus prevalence were lower in the IBD population than in the general population. Conversely, multiple sclerosis, primary sclerosing cholangitis, and pyoderma gangrenosum were more prevalent in IBD patients. Among the patients with a concomitant IMID, 79.8% had an aggressive disease course vs. 8.1% in the control group (p < 0.001). (4) Conclusions: This study underscores the frequency of IMIDs in IBD patients and their association with a more aggressive disease course. The recognition of concurrent IMIDs is crucial for comprehensive patient management, influencing therapeutic decisions and potentially improving outcomes.

Navigating Uncharted Waters: Comparative Analysis of Clinical Progression and Outcomes in Vestibular Schwannoma Patients with Papilledema and without Hydrocephalus, Versus Those without Papilledema and Hydrocephalus: A Comprehensive Institutional Insight.

BACKGROUND: Papilledema's association with hydrocephalus (HCP)-linked larger vestibular schwannoma (VS) is established but cases lacking concurrent HCP require further investigation. METHODS: This retrospective comparative observational study, conducted from July 2018 to July 2023, examined 120 VS patients undergoing surgery. Patients were categorized into Group 1 (papilledema without HCP) and Group 2 (no papilledema or HCP), with comprehensive data analyzed. RESULTS: In this study, Group 1 (14 patients with papilledema) and Group 2 (106 patients without papilledema or HCP) were compared. Group 1 was younger (mean age 27.21 ± 11.73 years) than Group 2 (mean age 54.66 ± 11.44 years). Both groups had similar symptom durations and tumor detection times. Group 1 had increased vascularity (P = 0.001), elevated cisterna magna protein levels (P = 0.001), and a higher incidence of neurofibromatosis 2 (P = 0.003). They also experienced longer surgeries (P = 0.001) and more blood loss (P = 0.001), leading to extended postoperative complications. Group 2 showed improved postsurgery visual outcomes (P = 0.001), better Glasgow Outcome Scores (P = 0.001), enhanced facial nerve preservation (P = 0.002), and improved hearing on follow-up (P = 0.003). Logistic regression analysis highlighted prolonged surgery duration (P = 0.057) and papilledema (P = 0.0001) as significant factors influencing visual improvement. CONCLUSIONS: Patients with VS require preoperative fundoscopy evaluation due to potential visual loss and papilledema, even without HCP. Early treatment initiation enhances visual and hearing outcomes. Meticulous surgery is vital given the lesion's hypervascular nature and adherence to surrounding structures. Preoperative embolization may aid in preserving neurovascular structures. In developing countries with higher blindness rates, judicious noncontrast computed tomography brain evaluation is crucial for timely detection and treatment initiation of lesions like VS.

HBV reactivation and clinical resolution in an isolated anti-HBc-positive patient during immune checkpoint inhibition.

BACKGROUND: Immune checkpoint inhibitor (ICI)-related liver injury is a growing concern as ICIs are increasingly used in cancer treatment regimens. Interestingly, ICIs have exhibited antiviral effects among patients with chronic hepatitis B virus (HBV). However, the underlying mechanisms remain unclear, and clinical data on patients with previous HBV infection/exposure and isolated anti-HBV core antibodies (IAHBcs) are lacking. METHODS: We report a case illustrating the dual effects of ICIs in a patient experiencing panlobular hepatitis and concurrent HBV reactivation. FINDINGS: A 68-year-old male patient positive for IAHBcs was admitted with panlobular hepatitis and HBV reactivation after receiving systemic chemotherapy (several months before admission) and ICI treatment (4 weeks before admission) subsequent to metastatic primary lung cancer (NSCLC stage IV). This was followed by a rapid and significant decrease of HBV DNA viral load before and during antiviral treatment. CONCLUSIONS: This unique case sheds light on the dynamics of ICI therapy in IAHBc-positive patients experiencing HBV reactivation during chemotherapy and underscores the dual impact of ICIs. Moreover, it emphasizes the need for assessment of HBV serology and prophylaxis in IAHBc-positive patients undergoing chemotherapy and ICI treatment.

Factors influencing the development of infantile traumatic brain injury with a biphasic clinical course and late reduced diffusion.

BACKGROUND: Infantile traumatic brain injury (TBI) with a biphasic clinical course and late reduced diffusion (TBIRD) has been reported as a type of TBI. However, it remains uncertain which pediatric patients with TBI develop TBIRD. METHODS: Patients with TBI who were admitted to our hospital and underwent magnetic resonance imaging (MRI) between December 2006 and October 2022 were included in this study. A diagnosis of TBIRD was made in patients with or suspected TBI, with initial symptoms being convulsions or disturbance of consciousness and late-onset subcortical reduced diffusion, the so-called bright tree appearance. Clinical features, neuroimaging (computed tomography (CT) and MRI) findings, laboratory data, and Tada score were retrospectively compared between TBIRD and non-TBIRD patients. Neurological prognosis was assessed using the Pediatric Cerebral Performance Category scale. RESULTS: Of 21 patients who met the inclusion criteria, a diagnosis of TBIRD was made in 7 patients (median age: 8 months). The factors contributing to TBIRD development were seizures lasting over 30 min as the initial symptom (5/7 in TBIRD vs. 0/14 in non-TBIRD), tracheal intubation during initial treatment (5/7 vs. 0/14), and brain parenchymal lesions on CT (3/7 vs. 0/14), suggesting that severe TBI may progress to TBIRD. The Tada score was more positive in patients with TBIRD (6/7) than in those without (0/14). CONCLUSIONS: It is important to monitor infant patients with severe TBI for the development of TBIRD. The Tada score can be a useful tool for TBIRD prediction.
