A case of invasive mucinous adenocarcinoma presenting with massive bronchorrhea.

An 80-year-old non-smoking woman was admitted to hospital due to persistent sputum production and dyspnea. She developed respiratory failure, and chest imaging revealed multifocal consolidation and cavities. Her respiratory status did not respond to antimicrobial treatment and progressively worsened, with massive sputum production of approximately 1 L per day, and she died 19 days after admission. The patient was diagnosed with invasive mucinous adenocarcinoma based on a postmortem needle biopsy of the lung. Clinicians should consider invasive mucinous adenocarcinoma in the differential diagnosis of patients who present with massive bronchorrhea and diffuse pulmonary cavity abnormalities.

Impact of pemafibrate in patients with metabolic dysfunction-associated steatotic liver disease complicated by dyslipidemia: A single-arm prospective study.

Background and Aim: This study aimed to clarify the efficacy and safety of 48-week pemafibrate treatment in patients with metabolic dysfunction-associated steatotic liver disease (MASLD) complicated by dyslipidemia. Methods: A total of 110 patients diagnosed with MASLD complicated by dyslipidemia received pemafibrate at a dose of 0.1 mg twice daily for 48 weeks. Results: The participants were 54 males and 37 females, with a median age of 63 (52-71) years. Besides improvement in lipid profile, significant reductions from baseline to 48 weeks of treatment were found in liver-related enzymes, such as aspartate aminotransferase, alanine aminotransferase (ALT), gamma-glutamyl transpeptidase, and alkaline phosphatase (P < 0.001 for all). A significant decrease in the homeostasis model assessment-insulin resistance (HOMA-IR) was observed in patients with insulin resistance (HOMA-IR ≥ 2.5) (4.34 at baseline to 3.89 at Week 48, P < 0.05). Moreover, changes in ALT were weakly correlated with those in HOMA-IR (r = 0.34; p < 0.05). Regarding noninvasive liver fibrosis tests, platelets, Wisteria floribunda agglutinin-positive Mac-2-binding protein, type IV collagen 7s, and the non-alcoholic fatty liver disease fibrosis score significantly decreased from baseline to Week 48. Most adverse events were Grades 1-2, and no drug-related Grade 3 or higher adverse events were observed. Conclusion: This study demonstrated that 48-week pemafibrate administration improved liver-related enzymes and surrogate marker of liver fibrosis in patients with MASLD. The improvement of insulin resistance by pemafibrate may contribute to the favorable effect on MASLD complicated by dyslipidemia.

Low vitamin D levels accelerates muscle mass loss in patients with chronic liver disease.

Sarcopenia frequently and progressively occurs in patients with chronic liver disease. This study aimed to clarify the relationship between vitamin D levels and muscle mass loss. A total of 166 patients with chronic liver disease were enrolled in this study. Skeletal muscle mass index (SMI) was measured by bioelectrical impedance analysis at baseline and after 1 year. The rate of change in SMI from baseline after 1 year was calculated: ΔSMI (%) = [(1-year SMI - baseline SMI) / baseline SMI] × 100. Muscle mass loss was defined as ΔSMI ≤ -2%. The median 25-hydroxyvitamin D was 15.2 (11.2-19.3) ng/mL. The median SMI were 6.8 (5.9-7.8) kg/m2 at baseline and 6.7 (5.9-7.6) kg/m2 after 1 year. The median ΔSMI was -1.23% (-2.21% to 1.61%). Multivariate analysis identified low 25-hydroxyvitamin D as an independent factor associated with muscle mass loss. The optimal cut-off value of 25-hydroxyvitamin D to predict muscle mass loss was 12.7 ng/mL. Muscle mass loss was found in 56.4% v.s. 18.0% of patients with 25-hydroxyvitamin D < 12.7 vs. ≥ 12.7 ng/mL, respectively (p = 9.01 × 10-7); with the highest incidence in patients with non-alcoholic fatty liver disease (NAFLD). Specifically, patients with NAFLD and 25-hydroxyvitamin D < 12.7 ng/mL had a significantly higher incidence of muscle mass loss than those with ≥ 12.7 ng/mL (p = 1.23 × 10-3). Low vitamin D levels are associated with muscle mass loss after 1 year in patients with chronic liver disease, especially NAFLD.

Desquamative Interstitial Pneumonia with Progressive Pulmonary Fibrosis.

A 70-year-old man who smoked was referred to our hospital because of progressive cough and dyspnea. Radiologic images showed ground-glass attenuation predominantly in the lower lung lobes. A surgical lung biopsy was performed, and a diagnosis of desquamative interstitial pneumonia (DIP) was made. The patient's symptoms improved with smoking cessation and steroid treatment, but the ground-glass attenuation did not completely resolve. At 10 years after the diagnosis, the fibrotic lesions deteriorated and treatment with nintedanib was subsequently initiated. Careful observation is needed in patients with DIP whose lung involvement does not completely improve with initial treatment.

A novel formula used for predicting hepatocellular carcinoma after the achievement of sustained virologic response by direct-acting antivirals in patients with chronic hepatitis C.

Although eliminating HCV can prevent hepatocellular carcinoma (HCC), some patients develop HCC even after obtaining sustained virologic response (SVR). Previously, we developed a new formula to predict advanced liver fibrosis. This study aimed to clarify the usefulness of this formula for predicting HCC after achieving SVR. Among 351 consecutive patients who had been treated with direct-acting antivirals, 299 were included in this study. New formula scores were used as a marker for predicting liver fibrosis and as a predictive model for HCC incidence. The participants were 172 men and 127 women with a median age of 68 years. The median new formula score was -1.291. The cumulative HCC incidence rates were 4.3%, 9.7%, and 12.5% at 1, 3, and 5 years, respectively. The cumulative incidence of HCC was significantly higher in patients with a history of HCC than in those without treatment history of HCC (P = 2.52×10-26). Multivariate analysis revealed that male (HR = 6.584, 95% CI = 1.291-33.573, P = 0.023) and new formula score (HR = 1.741, 95% CI = 1.041-2.911, P = 0.035) were independent factors associated with the development of HCC in patients without a treatment history of HCC. The optimal cutoff value for predicting the development of HCC was -0.214. The cumulative incidence rates of HCC in patients with new formula scores ≥-0.214 were 5.4%, 15.3%, and 15.3% at 1, 3, and 5 years, respectively, whereas the incidence rates of HCC in patients with new formula scores <-0.214 were 0.0%, 0.6%, and 4.8%, respectively (P = 2.12×10-4). In conclusion, this study demonstrated the usefulness of new formula scores as a predictor of HCC after achieving SVR, especially in patients without past treatment history of treatment for HCC.

Post-menopausal ovarian fibroma associated with steroid hormone synthesis: A case report.

OBJECTIVE: Ovarian fibromas are benign, sex cord-stromal tumors occurring in both peri- and post-menopausal women. Generally, these tumors are non-functional and do not produce hormones. However, this case report proves the first case of steroid hormone synthesis in an ovarian fibroma by immunohistochemistry. CASE REPORT: A 77-year-old post-menopausal woman presented with a left ovarian tumor, abnormal endometrial thickness, and high levels of estradiol (E2). The tumor was found to be a fibroma, which was positive for alpha-inhibin. We examined estrogen-producing enzymes using immunohistochemistry. The tumor was positive for estrogen receptor, progesterone receptor, 17ß-hydroxysteroid dehydrogenase (HSD)-1, adrenal 4 binding protein/steroidogenic factor 1, 17ß-HSD-5, steroid sulfatase, and P450c17. CONCLUSION: This case study shows that E2 can be locally produced from circulating inactive steroids, by estrogen-producing enzymes. This is the first report of steroid hormone synthesis in an ovarian fibroma.

[Analysis of Patients Discharged from a Palliative Care Unit].

For terminal-phase cancer patients, being discharged from a palliative care unit(PCU)is often challenging. To explore this reason, we compared patients who went home alive from the PCU with patients who died in the same unit. Among the survival cases, the average duration from their diagnosis to admission into the PCU was longer. Their slow progressions might allow them to leave the PCU. Patients with head and neck cancer were more often among those who died in the PCU, and the ratio of patient with endometrial cancer was higher in the survival cases. These ratios were relevant to the duration before their admission and variety of their symptoms.

Partial pressure of carbon dioxide levels reflect disease severity in idiopathic pleuroparenchymal fibroelastosis.

BACKGROUND: Hypercapnia can cause a disturbance of consciousness and adversely affect a patient's general condition. Patients with interstitial lung disease seldom experience hypercapnia. Hypercapnia is a typical phenomenon in patients with pleuroparenchymal fibroelastosis (PPFE), especially in advanced stages. However, the clinical significance of hypercapnia in patients with idiopathic PPFE (iPPFE) has not been studied in detail. METHODS: We retrospectively selected patients with iPPFE who had undergone blood gas analysis. The first blood gas data obtained after iPPFE diagnosis were examined. The partial pressure of carbon dioxide (PCO2) levels and their association with characteristic iPPFE parameters, including the flat chest index (the ratio of the anteroposterior diameter of the thoracic cage to the transverse diameter of the thoracic cage), were investigated. RESULTS: A total of 47 patients with iPPFE were included in this study. The PCO2 level was moderately and inversely correlated with the forced vital capacity. (r = -0.431, P = 0.014), flat chest index (r = -0.497, P < 0.001), and body mass index (r = -0.313, P = 0.038) and was positively correlated with residual volume/total lung capacity. (r = 0.514, P < 0.01). A higher PCO2 level was also significantly associated with poorer prognosis in patients with iPPFE. CONCLUSIONS: PCO2 levels could be used as an indicator of disease severity in patients with iPPFE.

Survey of psychiatric symptoms among inpatients with COVID-19 using the Diagnosis Procedure Combination data and medical records in Japan.

Physical symptoms such as fatigue and muscle weakness, and psychiatric symptoms like depression and anxiety are considered as complications and sequelae of COVID-19. This epidemiological study investigated the actual status of psychiatric symptoms and disorders caused by COVID-19, from four major university hospitals and five general hospitals in Fukuoka Prefecture, Japan, having a population of 5 million. We conducted a survey of psychiatric disorders associated with COVID-19 using Diagnosis Procedure Combination (DPC) data and the psychiatric records of the hospitals. In the study period from January 2019 to September 2021, 2743 COVID-19 admissions were determined from DPC data across the nine sites. These subjects had significantly more anxiety, depression, and insomnia, and were receiving higher rates of various psychotropic medications than controls influenza and respiratory infections. A review of psychiatric records revealed that the frequency of organic mental illness with insomnia and confusion was proportional to the severity of COVID-19 infection and that anxiety symptoms appeared independent of infection severity. These results indicate that COVID-19 is more likely to produce psychiatric symptoms such as anxiety and insomnia than conventional infections.
