Platelet and large platelet ratios are useful in predicting severity of COVID-19.

The role of platelets in coronavirus disease (COVID-19) severity requires further exploration. To determine whether the platelet index is useful in predicting COVID-19 severity, we compared the platelet index in patients with higher and lower oxygen requirements (≥ 4 L/min vs. < 4 L/min) and patients without COVID-19. We also analyzed the time course of the platelet index in each group. A total of 285 patients with COVID-19 and 36 without COVID-19 who were hospitalized at Fussa Hospital were analyzed. After matching for oxygen requirement at admission, multivariate analysis was performed. Platelets (≤ 16.6 × 104/µL) and platelet-large cell ratio (P-LCR) (≥ 27.8%) were significant factors influencing severity. Based on these factors, we created the Fussa platelet score, and the group with a Fussa platelet score ≥ 2 was significantly more likely to reach the 4 L/min oxygen requirement (event-free survival: Fussa platelet score ≥ 2 versus < 2, P < 0.00000001). Analysis of platelet index by time period showed a significant increase from 6-10 days after onset. The Fussa platelet score can be measured quickly, easily, and inexpensively in a clinic and may be useful in determining need for transfer to a critical care hospital.

Ravulizumab can effectively treat ischemic enteritis caused by paroxysmal nocturnal hemoglobinuria.

Ischemic colitis is a common disease with a good prognosis; however, complications can occur in the presence of a serious underlying disease. Herein, we present a case report in which characteristic findings on lower gastrointestinal endoscopy led to a diagnosis of paroxysmal nocturnal hemoglobinuria (PNH). An 82-year-old woman visited our hospital for chronic heart and renal failure. She had a history of breast cancer, myocardial infarction, and hemorrhoidal fistula and was initially hospitalized for ischemic colitis. Subsequent lower gastrointestinal endoscopy revealed extensive ulcerative lesions in the ascending, transverse, and descending colon. Histopathologically, small vessels exhibited multiple fibrin thrombus formations. Based on histopathological and endoscopic results, the presence of an underlying disease was suspected. Flow cytometric analysis showed that erythrocytes and granulocytes had 5.5 and 86.4% CD55- and CD59-negative cells, respectively. The patient was ultimately diagnosed with PNH and considered severely ill, given the ischemic colitis-induced abdominal pain and the need for red blood cell transfusions (4-6 units per month). Accordingly, the patient was administered ravulizumab. Ischemic enteritis did not relapse following ravulizumab administration, and transfusion dependence improved. If a patient with ischemic colitis presents atypical lower gastrointestinal endoscopic findings, it is important to explore the presence of an underlying disease.

Process of Regaining Self-Efficacy in Cancer Survivors Undergoing Gastrectomy

Purpose@#Patients with gastric cancer experience several challenges in regaining self-efficacy, including postoperative gastric dysfunction and psychosocial problems, after undergoing gastrectomy. This study aimed to describe the process of regaining self-efficacy in cancer survivors who underwent gastrectomy. @*Methods@#This study enrolled adults, employed a modified grounded theory approach, and targeted participants by theoretical sampling. Data were collected via semi-structured interviews and analyzed by qualitative and inductive methods. @*Results@#The participants included 10 post-gastrectomy patients with gastric cancer. The analysis yielded 28 concepts, eight categories, and four core categories. Regaining self-efficacy in cancer survivors began with “Facing gastric cancer and surgery.” After a period of being “At the mercy of gastrectomy and eating habits,” it changed to “Reclaiming life while accepting the loss of gastric function” through trial-and-error, and finally reached the stage of “Aiming for a better future than that before gastric cancer” after a long period. @*Conclusion@#Despite a crisis and repeated trial-and-error circumstances that could change abruptly, the patients demonstrated a flexible and resilient attitude in regaining self-efficacy. This study presented a time axis of the difficult process of regaining self-efficacy and explained the stages at which nursing intervention becomes important.

Clinical Characteristics and Risk Prediction Score in Patients With Mild-to-Moderate Coronavirus Disease 2019 in Japan.

BACKGROUND: Coronavirus disease 2019 (COVID-19) has rapidly spread worldwide, causing widespread mortality. Many patients with COVID-19 have been treated in homes, hotels, and medium-sized hospitals where doctors were responsible for assessing the need for critical care hospitalization. This study aimed to establish a severity prediction score for critical care triage. METHOD: We analyzed the data of 368 patients with mild-to-moderate COVID-19 who had been admitted to Fussa Hospital, Japan, from April 2020 to February 2022. We defined a high-oxygen group as requiring ≥4 l/min of oxygen. Multivariable logistic regression was used to construct a risk prediction score, and the best model was selected using a stepwise selection method. RESULTS: Multivariable analysis showed that older age (≥70 years), elevated creatine kinase (≥127 U/L), C-reactive protein (≥2.19 mg/dL), and ferritin (≥632.7 ng/mL) levels were independent risk factors associated with the high-oxygen group. Each risk factor was assigned a score ranging from 0 to 4, and we referred to the final overall score as the Fussa score. Patients were classified into two groups, namely, high-risk (total risk factors, ≥2) and low-risk (total risk score, <2) groups. The high-risk group had a significantly worse prognosis (low-risk group, undefined vs. high-risk group, undefined; P< 0.0001). CONCLUSIONS: The Fussa score might help to identify patients with COVID-19 who require critical care hospitalization.

Triaxial system in stent-graft placement for traumatic renal artery dissection: A case report.

Stent-graft placement is an important treatment for traumatic renal artery dissection, but it may occasionally be technically difficult to advance a catheter through the lesion of the dissection due to severe stenosis of the true rumen. A triple-coaxial (triaxial) system, which consists of a small microcatheter, a large microcatheter, and a 4-Fr. catheter, has recently become available, and it contributes to super-selective catheterization. We thought this system may be useful for passing catheters through the dissection. We herein report a 30-year-old male patient with traumatic renal artery dissection, who was successfully treated by stent-graft placement using the triaxial system.

Hypothyroidism is a Predictive Factor for Better Clinical Outcomes in Patients with Advanced Hepatocellular Carcinoma Undergoing Lenvatinib Therapy.

Patients with advanced hepatocellular carcinoma (HCC) undergoing molecular targeted therapy often experience non-negligible adverse events (AEs). Paradoxically, certain AEs are reportedly associated with a good prognosis. We aimed to identify factors predictive of treatment duration and overall survival (OS) in patients with HCC undergoing lenvatinib therapy. Forty-six consecutive patients with advanced HCC who received lenvatinib therapy from April 2018 to November 2019 were prospectively followed until November 2019. Treatment efficacy was assessed according to the modified Response Evaluation Criteria in Solid Tumors for 2-3 months after therapy initiation. The disease control rate (DCR) was defined as the percentage of patients with a complete response, partial response, or stable disease. The DCR was 65.2%, with a median survival of 10.2 months. Grade 2/3 hypoalbuminemia resulted in shorter treatment duration. Factors predictive of longer OS were a Child-Pugh score of 5 at baseline and the occurrence of Grade 2/3 hypothyroidism. Conversely, Grade 2/3 hypoalbuminemia was associated with a poorer prognosis. An AE of Grade 2/3 hypothyroidism was associated with a better prognosis in patients receiving lenvatinib treatment for advanced HCC. Continuing anticancer therapy with appropriate thyroid hormone replacement may contribute to longer OS.

Evaluation of the efficacy and safety of dienogest in the treatment of painful symptoms in patients with adenomyosis: a randomized, double-blind, multicenter, placebo-controlled study.

OBJECTIVE: To evaluate the efficacy and safety of dienogest (DNG), a progestational 19-norsteroid, in patients with symptomatic adenomyosis. DESIGN: Phase III, randomized, double-blind, multicenter, placebo-controlled study. SETTING: Clinical study sites in Japan. PATIENT(S): Sixty-seven patients with adenomyosis. INTERVENTION(S): Patients were randomly assigned to receive DNG (2 mg/d, orally) or placebo for 16 weeks. In cases of complicated anemia, patients were treated for anemia before randomization. MAIN OUTCOME MEASURE(S): The primary end point was the change from baseline to after treatment pain score, using zero- to three-point verbal rating scales that defined pain severity according to limited ability to work and need for analgesics. The visual analogue scale was used as another pain parameter. RESULT(S): Decreases from baseline in the pain score and the visual analogue scale at the end of treatment were significantly more in the DNG group than in the placebo group (P<.001). During the treatment period, almost all of the patients treated with DNG experienced irregular uterine bleeding and one patient had mild anemia. No severe cases of anemia were observed. CONCLUSION(S): These results suggest that DNG is effective and well tolerated in the treatment for painful symptoms associated with adenomyosis not complicated by severe uterine enlargement or severe anemia.

A pleckstrin homology-like domain is critical for F-actin binding and cofilin-phosphatase activity of Slingshot-1.

Slingshot-1 (SSH1) is a protein phosphatase that specifically dephosphorylates and activates cofilin, an F-actin-severing protein. SSH1 binds to and co-localizes with F-actin, and the cofilin-phosphatase activity of SSH1 is markedly increased by binding to F-actin. In this study, we performed a secondary structure analysis of SSH1, which predicted the existence of a pleckstrin homology (PH)-like domain in the N-terminal region of SSH1. SSH1 also contains a DEK-C domain in the N-terminal region. The N-terminal fragment of SSH1 bound to and co-localized with F-actin, but mutation at Arg-96 or a Leu-His-Lys (LHK) motif in the PH-like domain reduced this activity. Furthermore, mutation at Arg-96 abrogated the cofilin-phosphatase activity of SSH1 in the presence of F-actin. These results suggest that the N-terminal PH-like domain plays a critical role in F-actin binding and F-actin-mediated activation of the cofilin-phosphatase activity of SSH1.

Longitudinal alterations in health-related quality of life and its impact on the clinical course of patients with advanced hepatocellular carcinoma receiving sorafenib treatment.

BACKGROUND: This study aimed to identify the health-related quality of life (HRQOL) domains associated with prognosis by assessing longitudinal alterations in HRQOL in patients with advanced hepatocellular carcinoma receiving sorafenib. METHODS: We prospectively assessed HRQOL by administering the SF-36 questionnaire 3-monthly to consecutive patients with advanced hepatocellular carcinoma receiving sorafenib. We evaluated the impact of HRQOL on their overall survival and duration of treatment with sorafenib using Cox's proportional hazards model. RESULTS: There were 54 participants: 42 (78 %) were male, the median age was 71 years, 24 (44 %) had hepatitis C virus infection, 33 (61 %) had Child-Pugh scores of 5, and 30 (56 %) had TNM stage IV hepatocellular carcinoma. The median overall survival and treatment duration were 9 and 5 months, respectively, and 40 patients (74 %) died. Thirteen patients receiving sorafenib over a 1-year period maintained all domain scores >40, without a significant decline during the treatment period. In contrast, physical functioning, physical role, and vitality scores declined continuously and significantly in the year before death (in the 40 patients who died). Previous curative treatment and physical functioning scores ≥40 at baseline were significantly associated with longer overall survival by multivariate analysis. Social functioning scores ≥40, absence of vascular invasion, and lower DCP value were significant predictors of longer treatment duration. CONCLUSIONS: HRQOL was not significantly impaired in those patients who were able to complete a 1-year course of sorafenib treatment. Baseline physical functioning scores ≥40 and social functioning scores ≥40 were significantly associated with longer overall survival and longer treatment duration, respectively. Thus, HRQOL could be a valuable marker to predict the clinical course of patients with advanced hepatocellular carcinoma receiving sorafenib.
