Characteristics and Outcomes of ICU-admitted COVID-19 Patients in the Omicron and Alpha-dominated periods.

Comparing the outcomes of intensive care unit (ICU) admitted COVID-19 patients during the Alpha and Omicron-dominated periods. Patients with critical COVID-19 disease, requiring ICU admission from May to September 2021 and February to August 2022, were enrolled from a single medical center in Northern Taiwan. Clinical demographics, comorbidities, disease severity, and management strategies were recorded. The 28-day mortality from the two periods were compared both in the original and propensity score (PS)-matched cohort. Of 231 patients, 72 (31.2%) were from the Alpha period and 159 (68.8%) from the Omicron period. Patients in the Omicron period were older, had a lower body mass index, more comorbidities, higher disease severities, and increased 28-day mortality (26.4% vs. 13.9%, p=0.035). In multivariable analysis, the Omicron-dominated period was not identified as an independent factor associated with increased 28-day mortality. COVID-19 patients in Alpha- and Omicron-dominated periods had comparable 28-day mortality in PS-matched cohort (12.1% vs. 18.2%, p=0.733). Independent factors associated with 28-day mortality were a lower PF ratio (PF ratio <100, adjusted odds ratio [aOR] 2.68, 95% confidence interval, CI 1.21-5.94), septic shock ([aOR] 2.39, 95% CI 1.12-5.09) and absence of remdesivir ([aOR] 0.36, 95% CI 0.16-0.83). While patients in the Omicron period exhibited greater severity, the variant was not independently linked to higher 28-day mortality in ICU-admitted patients.

Real-world outcomes in patients with hereditary angioedema prescribed lanadelumab versus other prophylaxis.

Background: Hereditary angioedema (HAE) is a rare genetic disorder characterized by painful, debilitating, and potentially fatal swelling attacks. Lanadelumab is approved as long-term prophylaxis (LTP) in patients with HAE. However, real-world data on LTP use in patients with HAE are limited. Objective: To describe clinical characteristics, attack history, and quality of life (QoL) of patients with HAE type I/II who were receiving lanadelumab or other LTPs. Methods: Data were drawn from the Adelphi HAE Disease Specific Program, a cross-sectional survey of HAE physicians conducted in the United States from July to November 2021. Physician-reported disease characteristics, HAE attack frequency, and QoL were compared among patients receiving lanadelumab or other LTPs for at least 12 months. Results: Physicians reported data for 144 patients, of whom 29 had received lanadelumab and 115 had received another prophylaxis for at least 12 months. The mean ± standard deviation number of attacks in the previous 12 months was lower among patients receiving lanadelumab than other LTPs (2.3 ± 3.1 versus 3.4 ± 2.8, respectively; p = 0.075). Although both groups had similar current disease activity and severity, more patients receiving lanadelumab versus other LTPs had high disease activity (51.7% versus 12.5%, respectively; p < 0.0001) and disease severity rated as severe (51.7% versus 16.1%, respectively; p = 0.0001) at diagnosis. Physicians reported that more patients who received lanadelumab had good or very good QoL (72.4%) than those receiving other LTPs (36.5%) (p = 0.003). Conclusion: Analysis of these findings suggests lower attack frequency, lower symptomatic impact, and better QoL in patients treated with lanadelumab than another prophylaxis in a real-world setting.

Exploration of Factors Affecting Pro-social Intention to Disclose Information in Healthcare Settings

This study investigated the relationships of situational factors, motivational assessment–related factors, and situationally induced personal characteristics with pro-social intention to disclose patient information among health and medical students. In total, 210 students from Konyang University participated in the survey, including 116 medical students and 94 other health students. To measure the influence of variables on pro-social intention to disclose information related to health information security, a 27-item questionnaire was used. The reliability of the survey was shown by Cronbach’s α values of 0.859 to 0.917. According to students’ perceptions, higher disease severity was significantly related to higher impacts on the patient, family, and themselves (p&amp;lt;0.01), as well as higher situational empathy (p&amp;lt;0.05). Pro-social intention to disclose showed negative correlations with health information security awareness, information education experience, perceived impact on the self, responsibility to disclose, and personal norms (r=-0.136 to -0.647, p&amp;lt;0.05). Responsibility to disclose and situational empathy explained approximately 44% of the variance in pro-social intention to disclose. Additionally, students who received information security training perceived a significantly higher responsibility to disclose, exhibited higher health information security awareness, and had lower pro-social intention to disclose. This study confirmed the need for information security education for health and medical students, and suggested that pro-social characteristics such as empathy and responsibility need to be carefully addressed in information security education.

Outcomes and inflammation changes in different types of immunocompromised patients with critically ill COVID-19 admitted to ICU: a national multicenter study

BackgroundImmunocompromised patients face higher risks of Severe Acute Respiratory Syndrome Coronavirus 2 infection and co-infections, leading to a possibility of high disease severity and poor outcomes. Conversely, immunosuppression can mitigate the excessive inflammatory response induced by the virus, potentially reducing disease severity. This study aims to investigate the prognostic differences and early inflammatory response characteristics in various types of immunocompromised patients with severe coronavirus disease 2019 (COVID-19) admitted to intensive care unit (ICU), summarize their clinical features, and explore potential mechanisms.MethodsA retrospective analysis was conducted on critically ill COVID-19 patients admitted to the ICU of 59 medical centers in mainland China during the Omicron outbreak from November 2022 to February 2023. Patients were categorized into two groups based on their immunosuppression status: immunocompromised and immunocompetent. Immunocompromised patients were further subdivided by etiology into cancer patients, solid organ transplant (SOT) patients, and other immunocompromised groups, with immunocompetent patients serving as controls. The mortality rates, respiratory support, complications, and early inflammatory cytokine dynamics upon ICU admission among different populations were analyzed.ResultsA total of 2030 critically ill COVID-19 patients admitted to ICU were included, with 242 in the immunocompromised group and 1788 in the immunocompetent group. Cancer patients had a higher median age of 69 years (IQR 59, 77), while SOT patients were generally younger and had less severe illness upon ICU admission, with a median APACHE II score of 12.0 (IQR 8.0, 20.0). Cancer patients had a twofold increased risk of death (OR = 2.02, 95% CI 1.18–3.46, P = 0.010) compared to immunocompetent patients. SOT and cancer patients exhibited higher C-reactive protein and serum ferritin levels than the immunocompetent group in their early days of ICU admission. The CD8+ T cells dynamics were inversely correlated in cancer and SOT patients, with Interleukin-6 levels consistently lower in the SOT group compared to both immunocompetent and cancer patients.ConclusionCritically ill COVID-19 patients admitted to the ICU exhibit distinct clinical outcomes based on their immunosuppression status, with cancer patients facing the highest mortality rate due to variations in inflammatory responses linked to their immunosuppression mechanisms. Monitoring dynamic changes in inflammatory markers and immune cells, particularly CD8+ T lymphocytes and IL-6, may offer valuable prognostic insights for these patients.

Longitudinal relationships between free-living activities, fatigue, and symptom severity in myasthenia gravis using cohort and individualized models.

Fluctuating symptoms and fatigue are common issues in myasthenia gravis (MG), but it is unclear if these symptoms are related to physical activity or sleep patterns. This study sought to determine the day-to-day relationship between patient-reported symptoms and physical activity and sleep over 12 weeks. Sixteen participants with generalized MG wore a wrist-mounted accelerometer continuously for the study duration and reported their symptoms and fatigue each evening. Cumulative link mixed models were used to analyze whether clinical and demographic characteristics, physical activity, and sleep were related to symptom severity and fatigue over the study period. Three types of models were constructed: a cohort model, a model in which data was scaled to each participant, and individual models. The cohort model indicated that higher disease severity, female sex, more comorbidities, less physical activity, more inactive time, and lower quantity of sleep were significantly associated with increased symptom severity and fatigue (p < .05). However, in the within-participant scaled model, there were almost no significant associations with physical activity or sleep. In the individual models, some participants showed similar results to the cohort model, but others showed no associations or the opposite response in some variables. While physical activity and sleep were associated with self-reported symptoms and fatigue within this population, this was not necessarily applicable to individuals. This demonstrates the importance of an individualized analysis for determining how physical activity and sleep may impact outcomes in MG, with implications for clinical and self-management.

MAVS signaling shapes microglia responses to neurotropic virus infection

Viral encephalitis is characterized by a series of immunological reactions that can control virus infection in the brain, but dysregulated responses may cause excessive inflammation and brain damage. Microglia are brain-resident myeloid cells that are specialized in surveilling the local CNS environment and in case of viral brain infection they contribute to the control of the infection and to restriction of viral dissemination. Here, we report that after exposure to neurotropic vesicular stomatitis virus (VSV), murine in vitro microglia cultures showed rapid upregulation of a broad range of pro-inflammatory and antiviral genes, which were stably expressed over the entire 8 h infection period. Additionally, a set of immunomodulatory genes was upregulated between 6 and 8 h post infection. In microglia cultures, the induction of several immune response pathways including cytokine responses was dependent on mitochondrial antiviral-signaling protein (MAVS). Consequently, in Mavs-deficient microglia the control of virus propagation failed as indicated by augmented virus titers and the accumulation of viral transcripts. Thus, in the analyzed in vitro system, MAVS signaling is critically required to achieve full microglia activation and to mediate profound antiviral effects. In Mavs-deficient mice, intranasal VSV instillation caused higher disease severity than in WT mice and virus dissemination was noticed beyond the olfactory bulb. Virus spread to inner regions of the olfactory bulb, i.e., the granular cell layer, correlated with the recruitment of highly inflammatory non-microglia myeloid cells into the olfactory bulb in Mavs−/− mice. Furthermore, increased cytokine levels were detected in the nasal cavity, the olfactory bulb and in other brain regions. Thus, microglial MAVS signaling is critically needed for virus sensing, full microglia activation, and for orchestration of protective immunity in the virus-infected CNS.

Patient out-of-pocket expenditure in primary care comparing high income, middle income and low-income countries

Background: Out-of-pocket health expenditures (OOPHE) in primary care can pose a significant financial burden on individuals and households, particularly in low- and middle-income countries. Understanding the factors influencing OOPHE is crucial for developing effective policies to improve healthcare access and affordability. Objective: This systematic review aimed to identify and analyze the factors influencing OOPHE in primary care settings across high-, middle-, and low-income countries. Methods: A comprehensive search of electronic databases was conducted to identify relevant studies. Included studies were assessed for quality and data were extracted to identify key factors influencing OOPHE. Results: Demographic characteristics, socioeconomic factors, healthcare utilization, system factors, and cultural factors were all found to influence OOPHE. Lower income levels, limited insurance coverage, frequent healthcare utilization, and higher disease severity were consistently associated with higher OOP costs. Conclusion: The findings highlight the significant burden of OOP expenditures on individuals and households. Policymakers should prioritize strategies to expand health insurance coverage, improve access to primary care services, negotiate lower prices for healthcare goods, and address underlying socioeconomic factors. Further research is needed to explore the impact of specific interventions and the role of cultural factors in shaping OOP expenditures.

The FGL-1/LAG-3 Axis is Associated With Disease Course in Alcohol-associated Hepatitis: A Preliminary Report

BackgroundAlcohol-associated hepatitis (AH) has a short-term mortality rate of up to 40% primarily related to impaired hepatocyte regeneration and uncontrolled liver inflammation. The acute phase protein fibrinogen-like protein 1 (FGL-1) produced by hepatocytes stimulates hepatocyte proliferation by autocrine signaling. FGL-1 also is a ligand for the inhibitory T cell receptor lymphocyte activation gene 3 (LAG-3). In these ways, FGL-1 and LAG-3 have beneficial interactions that could be interrupted in AH. We aimed to characterize FGL-1 and LAG-3 in patients with AH and describe their relationship with the disease state and course. MethodsThirty-two patients with AH were included at diagnosis and followed up for 3 years. We measured the hepatic gene expression of FGL-1 and LAG-3 using RNA sequencing, plasma FGL-1 and soluble (s)LAG-3 using ELISA, and LAG-3+CD8+ T cells using flow cytometry. Healthy persons (HC) and patients with stable alcohol-associated cirrhosis served as controls. ResultsAt diagnosis of AH, liver FGL-1 mRNA was increased when compared to HC, whereas plasma FGL-1 was unchanged. In contrast, liver LAG-3 mRNA was reduced in AH. Plasma sLAG-3 levels and the frequency of LAG-3+CD8+ T cells were as in HC. However, those patients who had the lowest plasma FGL-1 and the lowest frequency of LAG-3+CD8+ T cells at diagnosis had the highest disease severity and mortality. ConclusionsOur data suggest that an impaired FGL-1/LAG-3 axis may be involved in the pathogenesis and course of AH.

Heart rate recovery after the 6-min walk test in people with bronchiectasis

BackgroundThe cardiac autonomic response to exercise and during recovery has been poorly explored in bronchiectasis.MethodsA longitudinal study was conducted in adults with bronchiectasis. Sociodemograhic and clinical data were collected at baseline and after 12 months of follow-up. The heart rate recovery after the first (HRR1) and second minute (HRR2) of recovery in the six-minute walk test (6MWT) was estimated in both assessments. Adjusted regression models were used to identify predictors of a delayed HRR1(HRR1≤ 14).Results104 participants with a mean (sd) age of 64 (13) years and mostly woman (67%) were included. A delayed HRR1after the baseline 6MWT was identified in 36% of participants. These participants presented a higher proportion of males, increased body mass index, higher disease severity, more likely to required hospitalisation, more impact on quality of life, lower exercise capacity, lower HR at the end of the 6MWT and lower HRR2. Disease severity (ß, 95%CI) (moderate and severeversusmild, −0.47 (−0.94 to −0.01)) and distance walked (0.34 (0.11 to 0.56)) were the independent variables associated with HRR1. Of the 45 participants who completed the entire follow-up period, 24% exhibited delayed HRR1. The presence of at least two exacerbations during the follow-up period (OR, 95%CI) (16.89 (1.44 to 197.48)) was the only predictor of a delayed HRR1in the assessment completed at the end of the study.ConclusionHRR1is related to disease severity and mainly affected by having severe exacerbations in people with bronchiectasis.

Associations between clinical data, vaccination status, antibody responses, and post-COVID-19 symptoms in Thais infected with SARS-CoV-2 Delta and Omicron variants: a 1-year follow-up study

BackgroundSevere acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), led to a global pandemic from 2020. In Thailand, five waves of outbreaks were recorded, with the fourth and fifth waves driven by the Delta and Omicron variants, resulting in over 20,000 new confirmed cases daily at their peaks.MethodsThis cross-sectional study investigated the associations between clinical symptoms, vaccination status, antibody responses, and post-COVID-19 sequelae in COVID-19 patients. Plasma samples and clinical data were collected from participants admitted to hospitals in Thailand between July 2021 and August 2022, with follow-ups conducted for one year. The study included 110 participants infected with either the Delta (n = 46) or Omicron (n = 64) variants. Virus genotypes were confirmed by RT-PCR of nasal swab RNA and partial nucleotide sequencing of the S gene. IgG and IgA antibody levels against the receptor-binding domain (RBD) of SARS-CoV-2 Delta and Omicron variants were measured in plasma samples using ELISA.ResultsPneumonia was found to be associated with Delta variant infections, while sore throat, congestion or runny nose, and headache were linked to Omicron infections. Vaccination with fewer than two doses and diabetes mellitus were significantly associated with higher disease severity. Specific IgG and IgA antibodies against the RBD of the Delta variant generally rose by day 14 and were maintained for up to two months, whereas the pattern of antibody response to the Omicron variant was less clear. Antibody risings were found to be positively associated with pneumonia, certain underlying conditions (obesity, hypertension, dyslipidemia, and diabetes mellitus), and age ≥ 60 years. Delta variant infections were associated with forgetfulness, hair loss, and headache during the 1-year post-infection period. Females were more likely to experience hair loss, forgetfulness, and joint pain, while older age was associated with joint pain.ConclusionsThis study enhances our understanding of SARS-CoV-2 infections in Thais, particularly concerning the Delta and Omicron variants. The findings can inform public health planning and response strategies for future outbreaks of SARS-CoV-2 or other emerging viral diseases.

IgG reactivity to different desmoglein-3 ectodomains in pemphigus vulgaris: novel panels for assessing disease severity.

Pemphigus vulgaris (PV) is an autoimmune disease characterized by IgG autoantibodies targeting desmoglein-3 (Dsg3), leading to blistering of mucous membranes and skin. Although commercial ELISA kits effectively diagnose PV, correlation with clinical phenotype remains unclear. This study assesses multiple panels for monitoring disease severity and activity by profiling IgG autoantibodies against Dsg3's various extracellular ectodomains. We designed and expressed different extracellular domains of Dsg3 in HEK293T cell line and developed 15 different ELISA panels, each using a single or multi ectodomains encompassing the entire extracellular region of Dsg3 to detect specific autoantibodies against the particular part of Dsg3. To validate our approach, we compared our ELISA panel for the full Dsg3 (EC1-5) against a commercial kit using 154 random serum samples from PV patients, demonstrating a strong correlation. For evaluation of IgG autoantibody profiles in our panels, 59 PV patients were included, along with 11 bullous pemphigoid patients, and 49 healthy controls. For all the included subjects, 15 predefined ELISA panels were tested. The IgG autoantibodies against EC1 were detected in 86% of patients with a positive full Dsg3 ectodomain (EC1-5) ELISA, with 26% against EC2, 14% for EC3, 29% for EC4, and 23% for EC5. Among the panels with multiple Dsg3 ectodomains, EC1-3 and EC1-4 were representative of the entire Dsg3 ectodomain in terms of ELISA positivity across all included patients. A significant correlation (P<0.05) was observed between ELISA optical density (OD) and Pemphigus Disease Area Index (PDAI) scores in five panels, EC1, EC2-3, EC2-5, and EC3-4 in addition to the full ectodomain. It suggests an association with disease severity. Interestingly, while the ELISA panel for the entire Dsg3 extracellular ectodomains did not differentiate disease phases, in three of our panels, including EC1, EC3-5, and EC2-5, ANOVA analysis showed a statistically significant difference between the groups of patients in remission, partial remission or persistent lesions, and those with active disease (new cases or relapse). Among these three panels, EC1 was the only one that showed a significant difference in the multiple comparisons analysis; patients in the active phase had higher levels of autoantibodies than those in 'partial remission or persistent lesions' and 'complete remission' groups. The level of autoantibodies against EC1 was not only correlated with the full ectodomain but also associated with higher disease severity and active disease phase. This study indicates that a detailed autoantibody profile against Dsg3 ectodomains could serve as a marker for PV severity and activity which may potentially enhance early treatment initiation.

Pseudoperonospora cubensis Causing Downy Mildew on Luffa aegyptiaca in Korea

In November 2021, sponge gourd (&lt;i&gt;Luffa aegyptiaca&lt;/i&gt;) plants with typical downy mildew symptom were observed in Korea. Based on morphological characteristics of sporangiophores and sporangia, combined with molecular phylogenetic analysis of the internal transcribed spacer rDNA and &lt;i&gt;cox&lt;/i&gt;2 mtDNA regions, the causal pathogen was identified as &lt;i&gt;Pseudoperonospora cubensis&lt;/i&gt; (Oomycota). This is the first report of downy mildew caused by &lt;i&gt;P. cubensis&lt;/i&gt; on &lt;i&gt;L. aegyptiaca&lt;/i&gt; in Korea. Given that &lt;i&gt;P. cubensis&lt;/i&gt; exhibits high disease incidence and severity on many Cucurbitaceae crops, it could pose a significant threat to sponge gourd cultivation.

Sepsis-associated acute kidney injury in patients with chronic kidney disease: Patient characteristics, prevalence, timing, trajectory, treatment and associated outcomes.

The features and outcomes of sepsis-associated acute kidney injury (SA-AKI) may be affected by chronic kidney disease (CKD). Accordingly, we aimed to compare SA-AKI in patients with or without CKD. Retrospective cohort study in 12 intensive care units (ICU). We studied the prevalence, patient characteristics, timing, trajectory, treatment and outcomes of SA-AKI with and without CKD. Of 84 240 admissions, 7255 (8.6%) involved patients with CKD. SA-AKI was more common in patients with CKD (21% vs 14%; p < .001). CKD patients were older (70 vs. 60 years; p < .001), had a higher median Charlson co-morbidity index (5 vs. 3; p < .001) and acute physiology and chronic health evaluation (APACHE) III score (78 vs. 60; p < .001) and were more likely to receive renal replacement therapy (RRT) (25% vs. 17%; p < .001). They had less complete return to baseline function at ICU discharge (48% vs. 60%; p < .001), higher major adverse kidney events at day 30 (MAKE-30) (38% vs. 27%; p < .001), and higher hospital and 90-day mortality (21% vs. 13%; p < .001, and 27% vs. 16%; p < .001, respectively). After adjustment for patient characteristics and severity of illness, however, CKD was not an independent risk factor for increased 90-day mortality (OR 0.88; 95% CI 0.76-1.02; p = .08) or MAKE-30 (OR 0.98; 95% CI 0.80-1.09; p = .4). SA-AKI is more common in patients with CKD. Such patients are older, more co-morbid, have higher disease severity, receive different ICU therapies and have different trajectories of renal recovery and greater unadjusted mortality. However, after adjustment day-90 mortality and MAKE-30 risk were not increased by CKD.

Identifying Palliative Care Needs in Patients With Heart Failure Using Patient Reported Outcomes

ContextHeart failure (HF) is considered a multifaceted and life-threatening syndrome characterized by high symptom-burden and significant mortality. ObjectivesTo describe the symptom-burden in patients with HF and identify their palliative care needs. In this respect, symptom burden related to sex, age and classification of HF using New York Heart Association Functional Classification (NYHA) were analyzed. MethodsA cross-sectional questionnaire survey included adult HF patients according to NYHA II, III, and IV. Palliative care needs were assessed using validated patient reported outcomes measures; SF-36v1, HeartQoL, EORTC- QLQ-C15-PAL, MFI-20 and HADS. Patients were recruited from the Department of Cardiology, North Zealand Hospital, Denmark. ResultsIn total, 314 patients (79%) completed the questionnaire (233 men). Mean age = 74 years (range 35–94 years). In all, 42% had NYHA III or IV and 53% self-rated their health to be fair or poor. In all, 19% NYHA II and 67% NYHA III/IV patients had ≥4 severe palliative symptoms according to EORTC-QLQ-C15-PAL. In addition, NYHA III/IV had a mean of 8.9 symptoms and a mean of 5.4 severe symptoms. Women, older patients, and those with NYHA III/IV had worse outcomes regarding health-related quality of life, functional capacity, and symptom burden. ConclusionsPatients with HF have a high prevalence of symptoms and, thus, potential palliative care needs. Predominantly, women, older patients, and those with higher severity of disease have the highest symptom burden. PROMs can help cardiologists address the palliative care needs and systematic assessment may be a prerequisite to integrate symptom-modifying and palliative care interventions.

Intensive care unit cardiac arrest among very elderly critically ill patients – is cardiopulmonary resuscitation justified?

IntroductionThe proportion of very elderly patients in the intensive care unit (ICU) is expected to rise. Furthermore, patients are likely more prone to suffer a cardiac arrest (CA) event within the ICU. The occurrence of intensive care unit cardiac arrest (ICU-CA) is associated with high mortality. To date, the incidence of ICU-CA and its clinical impact on outcome in the very old (≥ 90 years) patients treated is unknown.MethodsRetrospective analysis of all consecutive critically ill patients ≥ 90 years admitted to the ICU of a tertiary care university hospital in Hamburg (Germany). All patients suffering ICU-CA were included and CA characteristics and functional outcome was assessed. Clinical course and outcome were assessed and compared between the subgroups of patients with and without ICU-CA.Results1,108 critically ill patients aged ≥ 90 years were admitted during the study period. The median age was 92.3 (91.0–94.2) years and 67% (n = 747) were female. 2% (n = 25) of this cohort suffered ICU-CA after a median duration 0.5 (0.2–3.2) days of ICU admission. The presumed cause of ICU-CA was cardiac in 64% (n = 16). The median resuscitation time was 10 (2–15) minutes and the initial rhythm was shockable in 20% (n = 5). Return of spontaneous circulation (ROSC) could be achieved in 68% (n = 17). The cause of ICU admission was primarily medical in the total cohort (ICU-CA: 48% vs. No ICU-CA: 34%, p = 0.13), surgical - planned (ICU-CA: 32% vs. No ICU-CA: 37%, p = 0.61) and surgical - unplanned/emergency (ICU-CA: 43% vs. No ICU-CA: 28%, p = 0.34). The median Charlson Comorbidity Index (CCI) was 2 (1–3) points for patients with ICU-CA and 1 (0–2) for patients without ICU-CA (p = 0.54). Patients with ICU-CA had a higher disease severity according to SAPS II (ICU-CA: 54 vs. No ICU-CA: 36 points, p < 0.001). Patients with ICU-CA had a higher rate of mechanically ventilation (ICU-CA: 64% vs. No ICU-CA: 34%, p < 0.01) and required vasopressor therapy more often (ICU-CA: 88% vs. No ICU-CA: 41%, p < 0.001). The ICU and in-hospital mortality was 88% (n = 22) and 100% (n = 25) in patients with ICU-CA compared to 17% (n = 179) and 28% (n = 306) in patients without ICU-CA. The mortality rate for patients with ICU-CA was observed to be 88% (n = 22) in the ICU and 100% (n = 25) in-hospital. In contrast, patients without ICU-CA had an in-ICU mortality rate of 17% (n = 179) and an in-hospital mortality rate of 28% (n = 306) (both p < 0.001).ConclusionThe occurrence of ICU-CA in very elderly patients is rare but associated with high mortality. Providing CPR in this cohort did not lead to long-term survival at our centre. Very elderly patients admitted to the ICU likely benefit from supportive care only and should probably not be resuscitated due to poor chance of survival and ethical considerations. Providing personalized assurances that care will remain appropriate and in accordance with the patient’s and family’s wishes can optimise compassionate care while avoiding futile life-sustaining interventions.

Association of LIN28B Gene Polymorphisms with Intrauterine Adhesions in Patients after Curettage Abortion.

Background/Objectives: Intrauterine adhesion (IUA) is characterized by endometrial fibrocyte hyperplasia. The LIN28B gene is associated with many proliferative diseases. However, its association with IUA is entirely unknown. We hypothesized that LIN28B gene polymorphisms are responsible for IUA susceptibility after curettage abortion. Methods: In this genetic association study, We genotyped two common polymorphisms (rs369065 C>T and rs314280 A>G) in 107 patients with IUA and 270 controls without IUA after curettage abortion from a Chinese population between July 2022 and May 2023 and analyzed their associations with IUA risk using multiple logistic regression models. Results: The carriers of genotype rs314280 AA of the LIN28B gene showed an increased risk of IUA (AOR [adjusted odds ratio] = 2.12, 95% CI [confidence interval] = 1.151-3.903), compared to GG+GA genotypes. Further stratification analyses showed that the deleterious role of the rs314280 AA genotype was more evident in patients with fewer than four pregnancies (AOR = 2.740, 95% CI = 1.355-5.540), fewer than two births (AOR = 2.676, 95% CI = 1.300-5.509), and fibrous (AOR = 2.082, 95% CI = 1.084-3.997) and muscular adhesions (AOR = 3.887, 95% CI = 1.116-13.540). However, the rs369065 T>C polymorphism of the LIN28B gene was not significantly associated with the occurrence of IUA. Conclusions: The rs314280 AA genotype of the LIN28B gene is associated with an increased risk of IUA in patients after curettage abortion, especially in those with fewer pregnancies or parities and higher disease severity. Our findings implicate a precise choice of clinical counseling and decision-making of IUA, thereby protecting female reproduction.

Knowledge and Experience of In-Home Virtual Reality for Chronic Pain in Sickle Cell Disease

Many adults with sickle cell disease experience chronic, nonvaso-occlusive pain that can benefit from nonpharmacological interventions available for use in the home setting. Virtual reality (VR) has been shown to be effective in decreasing pain in chronic pain conditions and may be useful for home-based self-management of chronic pain in sickle cell. However, the literature lacks studies examining this potential. Additionally, the knowledge and experiences of adults with sickle cell who have tried VR for home-based chronic pain management have not yet been reported. This qualitative, descriptive pilot study explored the knowledge and perceptions of VR among adults with sickle cell and their experience with using in-home VR for chronic pain. Nine participants completed demographic questionnaires and an individual interview that was recorded, transcribed verbatim, and analyzed using thematic analysis. Participants were 21 to 38 years of age, and most were female (88.9%) with a medium or high sickle cell disease severity (88.9%) and a chronic pain-grade classification of grade III (high disability-moderately limiting) or grade IV (high disability-severely limiting) (55.5%). Interview themes, which aligned with the technology acceptance model, were 1) pain beliefs and self-management, 2) VR as another world, and 3) experience of using in-home VR. Based on preliminary data, VR shows promise as a strategy for nonpharmacological management of chronic pain in adults with sickle cell. However, further investigations are warranted to mitigate the challenges and limitations associated with using VR in this capacity. PerspectiveFew evidence-based, nonpharmacological interventions exist for chronic pain in adults with sickle cell disease. This first qualitative, pilot study of in-home VR for chronic pain in adults with sickle cell disease suggests that VR interventions need further exploration as a nonpharmacological strategy for mitigating their pain in the home setting.

Sarcopenia, frailty prevalence, and related factors in patients with stroke: A cross-sectional analytical study from Turkey.

Sarcopenia and frailty may develop at varying rates depending on the metabolic, structural, and functional changes in the muscle structure after stroke. To evaluate the prevalence of sarcopenia and frailty in patients with stroke and affecting clinical parameters. This was a cross-sectional and analytical study. Twenty-six (49.1%) women and 27 men (50.9%) with stroke with an average age of 60.2 ± 10.3 (median = 62) years were included in the study. To evaluate physical performance, balance, and mobility, we used the 4-meter walk test (4-MWT), timed up and go test, chair sit and stand test, and the Berg Balance Scale (BBS). Sarcopenia was diagnosed according to the Asian Working Group for Sarcopenia 2019 criteria. The SARC-F scale was used for sarcopenia. The average stroke duration was 21.6 ± 18.2 months. Prefrailty was present in 14 (26.4%) patients, frailty was present in 34 (64.2%) patients, and two (3.8%) patients were normal. Sarcopenia was detected in 28 (52.8%) patients. According to handgrip strength, the prevalence of low muscle strength was 17% (n= 9). In the sarcopenic group, female sex (p= 0.005) was more frequent, 4-MWT was longer (p= 0.003), chair stand test results were lower (p< 0.001), the clinical frailty scale (CFS) was higher (p< 0.001), fall risk was higher compared with the BBS (p< 0.001), there was lower HG strength (p= 0.009), lower malnutrition scores (PNI, prognostic nutritional index, p< 0.001), and lower lymphocyte counts (p= 0.037). EAT-10 scores and dysphagia presence (p= 0.026), the presence of malnutrition (p< 0.021) and Nottingham Health Profile score (p< 0.001) were higher in the sarcopenic group. Sarcopenia and frailty frequently develop in patients with chronic stroke, with low lymphocyte counts, physical performance, muscle strength, and mobility and balance scores, and it is associated with poor prognostic factors including high disease severity, dysphagia, malnutrition, risk of falling, and poor quality of life.

Influence of the Season of Year and Stage of Postharvest Processing on Anthracnose Severity in Bananas in a Savanna Climate in the Brazilian Northeast

ABSTRACTBanana cultivation has great socio‐economic importance in the Cariri region (state of Ceará), Brazil. This study aimed to monitor the severity of anthracnose (caused by Colletotrichum musae) in bananas (cv. Prata) collected at three postharvest processing steps (dehanding, first washing and second washing) in packinghouses of four producing companies (A, B, C and D) in the wet (February–May) and dry (September–December) seasons of production in 2019. Averaged across packing companies and processing stages, disease severity was higher in the wet season (42.4%) than in the dry season (19.6%), but disease variability, expressed by the coefficient of variation, was higher in the dry season. In most cases, there were significant (p ≤ 0.05) differences among processing stages within each packinghouse and season, but the stage with the highest disease severity was not consistent. In other words, there was no predictable change in disease severity from dehanding to first and second washing. It was impossible to identify a single pattern in the severity of anthracnose in banana fruits collected from different companies and stages of postharvest processing, and this may be associated with the management adopted in each production area.

Comparative analysis of neurofilaments and biomarkers of muscular damage in amyotrophic lateral sclerosis.

Diagnosis of the fatal neurodegenerative disease amyotrophic lateral sclerosis is challenging. Neurofilaments, indicative of neuronal damage, along with creatine kinase, creatinine, myoglobin, and troponin T, representing muscular damage, have been identified as promising fluid biomarkers. This study aims to comprehensively assess and compare their diagnostic and prognostic potential in a 'real-world' cohort of patients with amyotrophic lateral sclerosis. About 77 patients with amyotrophic lateral sclerosis and its clinical variants, and 26 age- and sex-matched controls with various neuromuscular and neurodegenerative diseases, were retrospectively included in this monocentric, cross-sectional study. Neurofilaments in cerebrospinal fluid and biomarkers of muscular damage in serum were measured and correlated with demographic features, motor function, survival time, clinical phenotypes, and the extent of upper and lower motor neuron involvement. Neurofilament, myoglobin, and troponin T concentrations were higher in patients with amyotrophic lateral sclerosis compared to disease controls. Higher neurofilament levels correlated with lower motor function and faster disease progression rate, while higher creatine kinase and creatinine concentrations were linked to preserved motor function. In contrast, troponin T elevation indicated poorer fine and gross motor functions. Increased neurofilament levels were associated with shorter survival, whereas biomarkers of muscular damage lacked survival correlation. Neurofilament concentrations were higher in classical amyotrophic lateral sclerosis than in progressive muscular atrophy, while myoglobin and troponin T levels were elevated in progressive muscular atrophy compared to primary lateral sclerosis. Neurofilaments were predominantly linked to upper motor neuron involvement. Our findings confirmed the robust diagnostic and prognostic value of neurofilaments in amyotrophic lateral sclerosis. Elevated neurofilament concentrations were associated with higher disease severity, faster disease progression, shorter survival, and predominant upper motor neuron degeneration. Biomarkers of muscular damage were inferior in distinguishing amyotrophic lateral sclerosis from other neuromuscular and neurodegenerative diseases. However, they may serve as complementary biomarkers and support in discriminating clinical variants of amyotrophic lateral sclerosis.
