RESUMEN
Thrombocytopenia is one of the common complications of cirrhotic patients, which can induce an increasing bleeding risk and closely correlate with bleeding following invasive procedures. Consequently, how to respond to thrombocytopenia is crucial for improving the prognosis of patients with cirrhosis. This article reviews the main mechanisms of cirrhosis concurrent with thrombocytopenia, as well as the corresponding clinical management strategies.

BACKGROUND: Delays in intravenous thrombolysis (IVT) treatment for acute ischemic stroke decrease the benefit of treatment. Difficulties determining a patient's clinical eligibility for IVT is a frequent cause of treatment delays. OBJECTIVE: We aimed to assess the effectiveness of the "PROVIDENCE" datasheet, a pre- hospital assessment of contraindications for IVT use applied by emergency medical services personnel. METHODS: We performed a single-center cohort study comparing IVT decision and treatment times between patients with PROVIDENCE datasheets and those without. Patients were eligible if they were over 18 years old and presented to our comprehensive stroke center from the field with stroke-like symptoms with onset within 4.5â¯hours. RESULTS: We identified 465 records and included 166 records in our final analysis (54 in the study group and 112 in the control group). A subgroup of 85 patients received IVT (30 in the study group patients and 55 in the control group). The PROVIDENCE datasheet was associated with a faster median time by five minutes from the patient's initial presentation at the emergency department to the final decision regarding IVT eligibility (p = 0.032) and a faster time between the first encounter with a neurology provider and the decision regarding IVT administration by six minutes (p = 0.002) for the entire sample. In the subgroup that received IVT, the PROVIDENCE datasheet decreased the median decision time by seven minutes (p = 0.044) There was no significant difference in door-to-needle times between groups. CONCLUSION: Using the PROVIDENCE datasheet, first responders can quickly identify potential contraindications for IVT treatment in patients with stroke-like symptoms. This tool expedited decision-making and led to faster IVT administration process at a comprehensive stroke center.

BACKGROUND: This study aimed to evaluate the implementation stage of Malaysia's GeKo-Integrated Service Delivery (ISD) model for frailty management in primary care and explore its effectiveness in improving frailty scores. METHODS: The implementation stage of Malaysia's first three GeKo- ISD clinics was assessed using the WHO-ICOPE (Integrated Care of the Older Persons) scorecard. This involved evaluating documents related to the GeKo services and conducting in-depth interviews with key informants identified from those documents. The efficacy of GeKo-ISD was assessed by documenting the change in mean frailty scores between baseline and 3 months post intervention, measured by the Pictorial Fit Frail Scale Malay Version (PFFS-M), in patients who received GeKo-ISD care from October 2022 to April 2023. RESULTS: All three GeKo clinics achieved the sustaining implementation level, scoring a total of 50 out of 52. The paired t-test reported a significant reduction (p= 0.001) in the PFFS-M scores from baseline to 3 months after the GeKo-ISD intervention. The mean (SD) scores were 8.6 (4.6) at baseline and 7.0 (4.1) at 3 months post-intervention. CONCLUSION: GeKo-ISD is a comprehensive approach of integrated care for older people, leveraging existing public funded primary care infrastructure. It shows promise, was impacted by the pandemic but now, with support from the government, exists in 32 centers across one state in Malaysia.

Undesirable outputs can be challenging to avoid in the production of goods and services, often overlooked. Pollution is generally regarded as a negative externality and is taken into account during the production process. The novelty of this study lies in introducing CO2 as an economic "bad" in the energy sector's efficiency measure through a stochastic data envelopment analysis (DEA) cross-efficiency model. Unlike pollution and economic goods, where increased production leads to more pollution, CO2 is weakly disposable, meaning that higher CO2 values lead to a decrease in the number of good outputs produced. The study proposes a new stochastic model based on an extension of the cross-efficiency model and applies it to measure the energy efficiency of 32 thermal power plants in Angola in the presence of undesirable outputs. This will help promote better environmental management. The study's findings offer vital policy insights for the energy sector. The introduction of new stochastic models enables more accurate efficiency measurement under uncertain conditions, aiding policymakers in resource allocation decisions. Additionally, the adoption of stochastic cross-efficiency methods enhances performance assessments, facilitating targeted interventions for underperforming units. These findings contribute to evidence-based policymaking, promoting sustainability and competitiveness within the energy sector.

As the plasma beta (ß) increases in high-performance tokamaks, electromagnetic turbulence becomes more significant, potentially constraining their operational range. To investigate this turbulence, a cross-polarization scattering (CPS) diagnostic system is being developed on the HL-3 tokamak for simultaneous measurements of density and magnetic fluctuations. In this work, a quasi-optical system has been designed and analyzed for the Q-band CPS diagnostic. The system includes a lens group for beam waist size optimization, a rotatable wire-grid polarizer for polarization adjustment, and a reflector group for measurement range regulation and system response enhancement. Laboratory tests demonstrated a beam radius of order 4 cm at the target measurement location (near the plasma pedestal), cross-polarization isolation exceeding 30 dB, and poloidal and toroidal angle adjustment ranges of ±40° and ±15°, respectively. These results verify the system's feasibility through laboratory evaluations. The quasi-optical system has been installed on the HL-3 tokamak during the 2023 experimental campaign to support the development of CPS diagnostics.
RESUMEN
Molecular docking is a popular computational tool in drug discovery. Leveraging structural information, docking software predicts binding poses of small molecules to cavities on the surfaces of proteins. Virtual screening for ligand discovery is a useful application of docking software. In this chapter, using the enigmatic KRAS protein as an example system, we endeavor to teach the reader about best practices for performing molecular docking with UCSF DOCK. We discuss methods for virtual screening and docking molecules on KRAS. We present the following six points to optimize our docking setup for prosecuting a virtual screen: protein structure choice, pocket selection, optimization of the scoring function, modification of sampling spheres and sampling procedures, choosing an appropriate portion of chemical space to dock, and the choice of which top scoring molecules to pick for purchase.

Objective: To investigate the clinicopathological features of Erdheim-Chester disease (ECD) initially diagnosed at extraskeletal locations. Methods: Clinical and pathological data of four cases of ECD diagnosed initially in extraskeletal locations were collected at Union Hospital, Tongji Medical College, Huazhong University of Science and Technology, from January 2013 to June 2023. BRAF V600E gene was detected by reverse transcription polymerase chain reaction (RT-PCR). Pertinent literatures were reviewed. Results: Four ECD patients included two males and two females ranging in ages from 2 years 11 months to 69 years. The lesions located in the lung (two cases), central nervous system (one case), and the testicle (one case) were collected in the study. One patient had occasional fever at night, one had nausea and vomiting, and two were asymptomatic. Radiologically, the two pulmonary ECD showed diffuse ground-glass nodules in both lungs, and the lesions in central nervous system and testicle both showed solid masses. Microscopically, there were infiltration of foamy histiocyte-like cells and multinucleated giant cells in a fibrotic background, accompanied by varying amounts of lymphocytes and plasma cells. The infiltration of tumor cells in pulmonary ECD was mainly seen in the subpleural area, interlobular septa, and perivascular and peribronchiolar areas. The fibrosis was more pronounced in the pleura and interlobular septa, and less pronounced in the alveolar septa. Immunohistochemical staining showed that all tumor cells expressed CD68, CD163 and Fô¼a; one case showed S-100 expression; three cases were positive for BRAF V600E; all were negative for CD1α and Langerin. RT-PCR in all four cases showed BRAF V600E gene mutation. Conclusions: Extraskeletal ECD is often rare and occult, and could be easily misdiagnosed, requiring biopsy confirmation. The radiologic findings of pulmonary ECD is significantly different from other types of ECD, and the histopathological features of pronounced infiltration in the subpleura area, interlobular septa, perivascular and peribronchiolar areas can be helpful in the differential diagnosis from other pulmonary diseases. Detection of BRAF V600E gene mutation by RT-PCR and its expression by immunohistochemical staining are also helpful in the diagnosis.

Cyclic GMP-AMP synthase (cGAS) is a DNA receptor that produces the second messenger cyclic GMP-AMP (cGAMP). cGAMP activates stimulator of interferon genes (STING), which initiates a signaling cascade leading to immune and inflammatory responses. This intricate molecular pathway plays a pivotal role in the pathogenesis and progression of diverse respiratory ailments, including respiratory infection, lung cancer, idiopathic pulmonary fibrosis, chronic obstructive pulmonary disease, asthma, and acute lung injury. Consequently, the cGAS-STING signaling pathway has emerged as a promising novel therapeutic target, opening up new avenues for the diagnosis and treatment of respiratory disorders. This review focuses on recent advances in our understanding of the cGAS-STING signaling pathway and its intricate involvement in respiratory system diseases.

BACKGROUND: The patient acceptable symptom state (PASS) refers to a cutoff value on any patient-reported outcome measures (PROMs) scale, beyond which patients consider themselves as having achieved an acceptable outcome. This study aimed to identify PASS thresholds for knee-specific and generic PROMs at 10 years post-unicompartmental knee arthroplasty (UKA). METHODS: There were 269 patients who underwent UKA for medial osteoarthritis from 2004 to 2007 at a single institution and were surveyed preoperatively and 10 years postoperatively using the Knee Society Function Score (KSFS), Knee Society Knee Score (KSKS), Oxford Knee Score (OKS), 36-Item Short Form Survey (SF-36) Mental Component Score (MCS), and SF-36 Physical Component Score (PCS). Treatment outcomes and expectations were assessed using an anchor question, and PASS attainment was determined using the Youden index on a receiver operating characteristic (ROC) curve. Also, a similar study that identified 2-year long-term PROM PASS thresholds for UKA was referenced and compared. RESULTS: Overall, 91.1% reported acceptable outcomes. The area under the curve for ROCs of KSKS, OKS, and PCS were 0.80, 0.75, and 0.71, respectively. The area under the curve for ROCs of KSFS and MCS were both 0.64. The PASS thresholds were 67.5 for KSFS, 70.5 for KSKS, 39.5 for OKS, 44.6 for PCS, and 43.8 for MCS. Patients who achieved a PASS were at least 3 times more likely to have satisfactory outcomes. CONCLUSIONS: To our knowledge, this is the first study that identified 10-year long-term PROM PASS thresholds for UKA. Accounting for our finding that a decade-long follow-up yielded lower PASS thresholds, time-specific UKA PROM PASS thresholds should be considered. LEVEL OF EVIDENCE: III.
RESUMEN
OBJECTIVE: The aim of this study was to examine the efficacy and safety of second-line immunotherapy and targeted treatment in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: From January 2000 to January 2023, ProQuest, PubMed, Web of Science, Scopus, Embase, and the Cochrane Library databases were searched for randomized controlled trials (RCTs) using immunotherapy or targeted therapy as second-line therapy for mid-to-advanced stages of HCC. Overall survival (OS), progression-free survival (PFS), and adverse events (AEs) are all examples of measures of success. RESULTS: This analysis included twenty Randomized Clinical Trials (RCTs) from phases II and III. Collective data revealed better OS with immunotherapy (HR = 0.79; 95% CI: 0.67, 0.93 vs. 0.85; 95% CI: 0.78, 0.92), while the targeted therapy played a more effective role in PFS (0.67; 95% CI: 0.56, 0.81). Also, the second-line immunotherapy had a lower odds ratio of AEs of grades 3-5 than the targeted therapy did (OR = 1.75; 95% CI = 0.89, 3.46). CONCLUSIONS: Overall, it appears that targeted medication and immunotherapy as a second-line treatment strategy have generally improved substantially, as well as progression-free survival for patients with mid-to-advanced HCC. Although it is difficult to judge their efficiency, the occurrences of AEs were greater in targeted therapy compared to immunotherapy.

Hirschsprung's Disease (HD) is a congenital disorder causing severe constipation in infants and children. Suction rectal biopsy (SRB) is the preferred technique for obtaining tissue samples for histopathological evaluation. In low-resource settings like Malaysia, cost-effective diagnostic approaches are necessary, making single sample SRB valuable. This study evaluates the diagnostic accuracy and sufficiency of a single macroscopically adequate sample in suction rectal biopsies for the histopathological confirmation of HD. We conducted a retrospective study of children who underwent suction rectal biopsies for the diagnosis of HD at Hospital Raja Perempuan Zainab II (HRPZII), Kota Bharu, Kelantan. A total of 68 patients were included in the study. The inadequacy rate for bedside SRB was 14%, comparable to current literature. Our study found no statistically significant association between sample inadequacy and gestational age, gender, birth weight, or weight at biopsy. Complication rates were 0%, consistent with literature reports. Calretinin staining, an additional technique, was performed in 23 biopsy episodes, with a 4.3% inadequacy rate, compared to 20% in specimens not subjected to calretinin staining. The cost of SRB almost doubled with each additional sample taken, significant in low-resource environments. In conclusion, single sample SRBs can be adequately diagnostic and cost-effective in low-resource settings, providing valuable insights for healthcare facilities in Malaysia and other developing countries. The use of adjunctive techniques such as calretinin staining may improve diagnostic accuracy while maintaining cost-effectiveness. Further prospective studies with larger sample sizes are needed to validate these findings.

Two-dimensional (2D) materials offer a prospect of membranes that combine negligible gas permeability with high proton conductivity and could outperform the existing proton exchange membranes used in various applications including fuel cells. Graphene oxide (GO), a well-known 2D material, facilitates rapid proton transport along its basal plane but proton conductivity across it remains unknown. It is also often presumed that individual GO monolayers contain a large density of nanoscale pinholes that lead to considerable gas leakage across the GO basal plane. Here we show that relatively large, micrometer-scale areas of monolayer GO are impermeable to gases, including helium, while exhibiting proton conductivity through the basal plane which is nearly two orders of magnitude higher than that of graphene. These findings provide insights into the key properties of GO and demonstrate that chemical functionalization of 2D crystals can be utilized to enhance their proton transparency without compromising gas impermeability.
RESUMEN
Objective: To explore whether the survival benefit of the third-line extensive small-cell lung cancer (ES-SCLC) will be obtained by the combination of anlotinib and radiotherapy, and evaluate the safety of this treatment regimen. Methods: Twenty-seven patients with ES-SCLC who received third-line treatment with less than three metastatic organs at the Cancer Hospital of Xinjiang Medical University from November 2018 to July 2021 were collected and treated with radiotherapy based on anlotinib. Kaplan-Meier curve was used to estimate the overall survival (OS) and progression-free survival (PFS), descriptive statistical analysis was used to evaluate the safety, and European organisation for research and treatment of cancer quality of life questionnaire-core 30 (EORTC QLQ-C30) was used to evaluate the quality of life. Results: The follow-up cut-off date was July 1, 2021, and the follow-up time ranged from 4.8 to 31.0 months, with a median follow-up time of 10.2 months for the entire group. Among the 27 patients, 4 achieved partial remission, 17 had stable disease and 6 had progression of disease. The objective remission rate (ORR) was 14.8%, and the disease control rate (DCR) was 77.8%. Median PFS and the median OS were 5 months and 11 months, respectively. The most common adverse reactions included fatigue (33.3%, 9/27), anorexia (14.8%, 4/27), bleeding (14.8%, 4/27) and hand-foot syndrome (11.1%, 3/27). Most of them were grade 1 to grade 2, 3 cases were more than grade 3, and there was no grade 5 toxicity recorded. After radiotherapy combined with amlotinib treatment, patients showed improvement in general health, somatic functioning, social functioning, and emotional functioning (all P<0.05). Conclusion: For the third-line ES-SCLC patients, radiotherapy based on the anlotinib can significantly prolong their PFS and OS, and the adverse reactions can be tolerated.

Objective: To evaluate the association between pre-and post-diagnosis body mass index (BMI) and risk of colorectal cancer (CRC) death. Methods: The cohort consisted of 3, 057 CRC patients from Shanghai who were diagnosed from Jan. 1, 2009 to Dec. 31, 2011 and aged from 20 to 74 years. The pre- and post-diagnosis BMI and clinical and lifestyle factors were collected at baseline. Death information was collected using record linkage with the Shanghai Cancer Registry and telephone confirmation during follow-up by the end of 2019. The Cox proportional regression model was used to estimate HR with 95% CI. Results: Analysis by multivariable Cox model showed no association between pre-diagnosis BMI and death risk in both male and female patients. Male patients with a post-diagnosis underweight BMI had an elevated risk of death compared to those in normal weight (HR=1.69, 95% CI: 1.21-2.37), especially in early stage cases. Overweight patients (HR=0.74, 95% CI: 0.61-0.89) and patients with obesity class â (HR=0.63, 95% CI: 0.45-0.89)had better survival with decreased risks of death, especially in advanced stage cases. The decreased death risk in patients with obesity class â ¡ was not significant (HR=0.57, 95% CI: 0.24-1.39). The P(trend) value for decreased risk of death with increased BMI in female patients was statistically significant (P<0.001), and the overweight and obesity class â categories had better survival in advanced stage(HR(overweight)=0.62, 95% CI: 0.42-0.93; HR(obesity class â )=0.39, 95% CI: 0.16-0.98). Both male and female patients with post-diagnosis BMI loss >2.0 kg/m(2) had an increased death risk when compared with those with stable BMI (change≤1.0 kg/m(2)) between pre- and post-diagnosis. BMI gain after diagnosis did not change death risk. Conclusions: Post-diagnosis BMI in the overweight or obesity class â groups might be conducive to prolonging male CRC patients' survival, while underweight might result in poor prognosis. Keeping weight and avoiding excessive weight loss should be suggested for all CRC patients after diagnosis.
