Dystextia and dystypia due to phonological errors after ischemic stroke: a case report in a Japanese patient.

A 69-year-old Japanese male presented with acute dystextia and dystypia, defined as texting and typing impairments, respectively. His text input speed decreased due to a phonologically incorrect kana flick input on his smartphone. Additionally, dystypia occurred due to phonemic paragraphia of Romaji. Brain MRI revealed a new left lenticulostriate infarction sparing the cerebral cortex. SPECT showed reduced cerebral blood flow in the left inferior precentral frontal gyrus as well as in the infarction area. It was concluded that his abnormal phonological processes resulted from hypoperfusion in the left inferior precentral gyrus that is assumed to be an endpoint of the arcuate fasciculus.

A multicenter randomized trial comparing rabeprazole and itopride in patients with functional dyspepsia in Japan: the NAGOYA study.

The aims of this study were to compare the therapeutic effects of a proton pump inhibitor (PPI), rabeprazole (RPZ), and a prokinetic agent, itopride (ITO), and to investigate the role of PPI in the treatment strategy for Japanese functional dyspepsia (FD) patients. We randomly assigned 134 patients diagnosed by Rome III criteria to 4 weeks treatment with RPZ 10 mg/day (n = 69) or ITO 150 mg/day (n = 65). Dyspeptic symptoms were evaluated using FD scores at baseline and after 1, 2 and 4 weeks of treatment. We also divided subjects into predominantly epigastric pain syndrome (EPS) or postprandial distress syndrome (PDS), and evaluated the efficacy of RPZ and ITO respectively. RPZ showed a significant decrease in the Rate of Change (RC) in FD score within 1 week, which was maintained until after 4 weeks, with RPZ a significant effect compared with ITO at all evaluation points. In addition, RPZ showed a significant decrease in FD score in subjects with both EPS and PDS, whereas a significant decrease in the RC with ITO was only shown in those with predominant PDS. Acid-suppressive therapy with RPZ is useful for PDS as well EPS in Japanese FD patients (UMIN Clinical Trials Registry number: UMIN 000013962).

Adult-onset Krabbe disease presenting with an isolated form of peripheral neuropathy.

INTRODUCTION: Adult-onset Krabbe disease is clinically rare and usually affects the pyramidal tracts in the central nervous system. Patients develop a spastic gait, and peripheral neuropathy sometimes occurs simultaneously. METHODS: A 55-year-old woman with consanguineous parents developed slowly progressive, asymmetric muscle weakness and atrophy in her forearms, while her ability to walk remained unaffected without pyramidal tract signs after onset at age 51 years. RESULTS: Nerve conduction studies demonstrated an asymmetric demyelinating-type peripheral neuropathy, and sural nerve biopsy documented reduced myelinated nerve fiber density with uniformly thin myelin sheaths, suggesting hypomyelination. Brain MRI demonstrated minor white-matter injury along the optic radiations, which was associated with asymptomatic, mild, prolonged latency on visual evoked potentials. Laboratory analysis documented low enzyme activity of galactocerebrosidase (GALC) and a known mutation of the GALC gene. CONCLUSION: Isolated peripheral neuropathy occurs very rarely in adult-onset Krabbe disease. Muscle Nerve 54: 152-157, 2016.

The Association Between the Frequency of Agriculture and Control of Chronic Diseases Among Regular Patients in Rural Community Hospitals: A Cross-Sectional Study.

Introduction The importance of exercise in chronic disease management among older people is paramount, especially as the global population ages and the prevalence of chronic diseases such as cardiovascular disease, diabetes, and arthritis increases. Regular physical activity enhances cardiovascular health, improves metabolic function, and alleviates symptoms of musculoskeletal disorders. As a form of exercise, agriculture provides physical and mental benefits for older adults. However, its impact on chronic disease management can be mixed, as the physical demands and potential stress associated with agricultural tasks can exacerbate certain health conditions. Method This cross-sectional study was conducted in Unnan City, a rural area in Japan, focusing on residents aged 40 and older who regularly visited Unnan City Hospital. Data were collected from 647 participants between September 1, 2023, and November 31, 2023, through questionnaires and electronic medical records. The primary outcome was the management of chronic diseases, assessed through hypertension, dyslipidemia, diabetes mellitus, and obesity control. Participants reported their frequency of agricultural activities, exercise, eating habits, and sleep. Statistical analyses included t-tests, Mann-Whitney U tests, and multivariate logistic regression models. Results Participants engaging frequently in agricultural activities were younger, had better hypertension control, and reported healthier eating habits and sleep patterns. Frequent agricultural activities were associated with a lower likelihood of hypertension (OR: 0.62, 95% CI: 0.39-0.97, p = 0.034). Older age (≥75 years), higher BMI (≥25), and a Charlson comorbidity index (CCI) score of ≥5 were significantly associated with hypertension. No significant associations were found between hypertension and other health-related variables such as healthy eating, adequate sleep, and regular exercise. Conclusion The study highlights the potential benefits of agricultural activities in managing chronic diseases, particularly hypertension, among older adults. However, the physical demands and possible social isolation associated with agricultural tasks require a nuanced approach to promoting these activities. Tailored, community-based agricultural programs that foster social interaction and support can enhance physical and mental health benefits. Future research should focus on longitudinal studies to confirm these findings and explore the long-term health outcomes of agricultural activities in diverse contexts.

Association Between Pneumococcal Vaccination Uptake and Loneliness Among Regular Patients in Rural Community Hospitals: A Cross-Sectional Study.

Introduction Vaccination is essential for preventing infectious diseases such as pneumonia and seasonal viral infections. The COVID-19 pandemic has underscored the critical role of vaccination in public health. However, vaccination uptake can be influenced by biopsychosocial conditions. Immunocompromised individuals, for instance, face restrictions with live vaccines, and psychosocial factors like loneliness can negatively impact attitudes towards vaccination. This study aims to clarify the association between loneliness and pneumococcal vaccination rate among regular patients in a rural Japanese community. Method A cross-sectional study was conducted at Unnan City Hospital in Unnan City, a rural area in southeastern Shimane Prefecture, Japan. Participants included patients over 40 who regularly visited the general medicine department between September 1, 2023, and November 31, 2023. Data on vaccination rates for pneumococcal pneumonia and loneliness levels assessed using the Japanese version of the three-item University of California, Los Angeles (UCLA) Loneliness Scale were collected. Additional data on demographics, BMI, renal function, and comorbidities were extracted from electronic medical records. Statistical analyses were performed to identify factors associated with vaccination rates, including univariate and multivariate logistic regression. Results Out of 1,024 eligible patients, 647 participated in the study. Participants with higher loneliness had significantly lower vaccination rates for pneumococcal pneumonia (22.3% vs. 34.2%, p = 0.001). The multivariate logistic regression model showed that higher loneliness was significantly associated with lower vaccination likelihood (odds ratio (OR) = 0.54, 95% CI = 0.37-0.78, p = 0.0011). Age was positively associated with vaccination (OR = 1.08, 95% CI = 1.06-1.11, p < 0.001), whereas higher comorbidity scores (Charlson Comorbidity Index (CCI) ≥ 5) and frequent healthy eating practices were associated with lower vaccination rates. Conclusion This study demonstrates a significant association between higher loneliness levels and lower pneumococcal vaccination rates among patients in a rural Japanese community. Addressing psychosocial barriers such as loneliness could enhance vaccination uptake. Public health interventions focused on reducing loneliness and enhancing social support are essential to improving vaccination rates and preventing infectious diseases. Further research should explore the causal mechanisms and develop targeted strategies to mitigate the impact of loneliness on health behaviors.

Linking Agricultural Activity Frequency to Loneliness in Rural Hospital Patients: A Cross-Sectional Study.

Introduction Agriculture is deeply woven into the fabric of rural life, influencing the economy, and the social and health dynamics of rural communities. While it offers physical and mental health benefits through regular physical activity and interaction with nature, the solitary nature of farming activities may also lead to social isolation. This study explores the complex relationship between the frequency of agricultural engagement and feelings of loneliness among rural inhabitants with chronic diseases, addressing a gap in the literature concerning the impact of agricultural practices on social well-being. Method A cross-sectional analysis was conducted among patients over 40 who frequented the general medicine department in Unnan City, a rural area of Japan. The study utilized the Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale to assess loneliness and collected data on agricultural activity frequency through questionnaires. Multivariate logistic regression analyses examined the association between agricultural activities and loneliness, controlling for demographic and health-related variables. Results Among 647 participants, higher frequencies of agricultural activities were significantly associated with increased loneliness, especially for individuals engaging in agriculture four to five times weekly or daily. Engaging in agricultural activities four to five times weekly and daily significantly increased the likelihood of higher loneliness levels, with odds ratios (OR) of 1.80 (p = 0.039) and 2.47 (p < 0.01), respectively, when compared to engagement less than once a week. Age emerged as an influential factor, with individuals aged 75 and older showing increased odds of experiencing higher loneliness (OR 1.56, p = 0.025). Conclusion The study underscores the dual nature of agricultural engagement in rural communities, highlighting its role in both supporting physical health and contributing to social isolation. These findings advocate for developing targeted interventions that mitigate loneliness among rural populations, suggesting the need for a balanced approach that encompasses social and healthcare strategies to enhance the overall well-being of individuals engaged in agriculture.

The Association Between Community Participation and Loneliness Among Patients in Rural Community Hospitals: A Cross-Sectional Study.

Introduction Loneliness among adults is a critical public health issue, particularly in rural areas where social isolation can be more pronounced. Understanding the factors that influence loneliness can guide the development of effective interventions. This study explores the impact of demographic, health-related, and social participation factors on loneliness among rural Japanese adults, focusing on the role of community participation. Method This cross-sectional study was conducted with rural Japanese adults who regularly visited rural community hospitals. Data were collected on participants' demographic characteristics, health status, and social participation and analyzed using a multivariate logistic regression model to identify factors associated with higher levels of loneliness. The covariates included age, sex, body mass index (BMI), chronic health conditions, and community participation. Results The study found that community participation had a significant negative association with loneliness, with an odds ratio (OR) of 0.46 (p < 0.01), indicating that individuals engaged in community activities were substantially less likely to experience higher levels of loneliness. Higher BMI was associated with lower odds of loneliness (OR = 0.93, p < 0.02), suggesting a protective effect against loneliness. Conclusion The findings highlight the paramount importance of community engagement in mitigating loneliness among rural Japanese adults. The inverse relationship between BMI and loneliness suggests that BMI and social participation influence loneliness. These insights underscore the need for comprehensive interventions that promote community participation and address the multifaceted nature of loneliness. Future research should further explore the mechanisms through which community engagement and BMI impact loneliness to develop targeted strategies for improving the well-being of rural adults.

The Association Between Community Dialogue and Loneliness in Rural Japanese Communities: A Cross-Sectional Study.

Introduction This investigation explores the influence of community dialogue on loneliness within rural Japanese communities amidst the backdrop of globalization, urbanization, and technological shifts. Highlighting the significance of both informal and formal community dialogues, the study aims to bridge the gap in empirical evidence regarding the role of these interactions in enhancing social cohesion and mitigating loneliness, particularly in rural areas facing demographic changes and privacy concerns. Method A cross-sectional study was performed in Unnan City, Japan, targeting individuals over 40 who regularly visited a local rural hospital. The study employed the Japanese version of the University of California, Los Angeles (UCLA) Loneliness Scale and questionnaires regarding the frequency of community dialogue, alongside examining participants' health and demographic details from hospital records. Analysis methods included t-tests, Mann-Whitney U tests, and multivariate logistic regression to examine the association between community dialogue frequency and loneliness. Results Among the 647 respondents, the participants' mean age was 71.26 years, with a male rate of 46.3%. The multivariate logistic regression analysis revealed that higher frequencies of community dialogue significantly reduce the odds of experiencing loneliness. Specifically, compared to individuals with the least frequency of community dialogue, those with more frequent and most frequent dialogues were significantly more likely to report higher loneliness levels, with odds ratios of 2.62 (95% CI: 1.60-4.29, p<0.01) and 4.11 (95% CI: 2.47-6.85, p<0.01), respectively. Additionally, an increase in BMI was inversely related to loneliness (OR: 0.95, 95% CI: 0.91-0.99, p=0.023), and individuals with a higher comorbidity index (CCI≥5) showed a decreased likelihood of reporting higher loneliness (OR: 0.64, 95% CI: 0.43-0.96, p=0.031). Conclusion This study shows compelling evidence that more frequent community interactions are inversely associated with feelings of loneliness. These findings suggest that initiatives to increase community dialogue need a nuanced approach to mental health and social cohesion in rural settings. The research further reveals an intriguing relationship between body mass index, the severity of comorbidities, and loneliness, offering insights into the complex interplay between physical health and social well-being. The importance of this study lies in its potential to inform policies and programs designed to foster social connections respecting rural contexts, thereby addressing the challenge of loneliness in rural communities.

Community Health Dialogue Implementation for the Solution of Loneliness in Rural Communities: Autoethnography.

INTRODUCTION: Isolation and loneliness among older adults in rural communities pose significant risks to physical and mental health, leading to higher rates of morbidity and mortality. This study investigates the impact of continual rural health dialogues facilitated by family physicians on reducing loneliness and enhancing community health in Unnan City, Shimane Prefecture, Japan. METHOD: Using a constructivist grounded theory approach, we conducted a qualitative study involving 165 participants over 65 from five rural communities between April 2022 and March 2024. Monthly health dialogues covered chronic diseases, exercise, and polypharmacy. Data were collected through ethnographic observations, focus group interviews, and field notes, with iterative coding and analysis to identify themes and concepts. RESULTS: Three primary themes emerged: the existence of loneliness and its impact on health, motivation to address loneliness through a sense of security, and recognition of the importance of community engagement in reducing loneliness. Participants reported increased health awareness, enhanced community interaction, and recognition of loneliness's prevalence and health impacts. Regular dialogues fostered trust with healthcare professionals, encouraged proactive health management, and facilitated supportive community connections. These interactions significantly reduced feelings of loneliness and improved health outcomes. CONCLUSION: Continual rural health dialogues effectively mitigate loneliness and enhance health outcomes in rural communities by fostering regular interactions and building supportive networks. These findings underscore the importance of community engagement and continuous relationships with healthcare professionals in addressing loneliness. Policymakers and healthcare providers should consider integrating such dialogues into rural health strategies to promote healthier, more connected communities. Future research should explore these interventions' long-term sustainability and broader applicability across diverse rural settings.

Drainage by Ovarian Incision for the Treatment of Massive Ovarian Edema Torsion During Pregnancy.

Massive ovarian edema (MOE) is a rare benign condition presenting as unilateral ovarian enlargement with stromal edema, and only a limited number of MOE cases during pregnancy have been reported. MOE is often complicated by ovarian torsion, which requires detorsion. Although the diagnosis of MOE can be made using ultrasound and magnetic resonance imaging, its rarity makes diagnosis difficult, usually leading to overtreatment. Preserving the ovary in the treatment of MOE torsion is essential, and consideration of oophoropexy after detorsion is often reported. However, fixing an enlarged ovary to the pelvic wall in the limited space of the pelvis is challenging. Herein, we present a case of MOE of the right ovary diagnosed at the fifth week of gestation after ovulation induced by clomiphene citrate. Torsion of the ovary occurred in the seventh week. We achieved preservation of the ovary through laparoscopic surgery with detorsion and drainage by making a small incision to the enlarged ovary, resulting in an immediate size reduction. There was no recurrence of torsion or MOE throughout the pregnancy, and the patient gave birth in the 39th week of gestation. This is the third reported case of MOE after ovulation using clomiphene citrate, and it highlights the effectiveness of treatment with detorsion and a small incision of the ovary via laparoscopic surgery in patients with MOE torsion during pregnancy.

The Usefulness of Magnetic Resonance Imaging in the Management of Acute Phlegmonous Esophagitis.

Acute phlegmonous esophagitis is a rare life-threatening disease that often requires surgical intervention in case of complications, including esophageal abscess, perforation, or mediastinitis. We present a case of acute phlegmonous esophagitis, in which magnetic resonance imaging (MRI) proved useful in planning the treatment strategy. An 89-year-old woman was admitted to the emergency department with painful swallowing and respiratory distress. She was diagnosed with acute phlegmonous esophagitis and a hypopharyngeal abscess based on computed tomography (CT) findings. However, there was a discrepancy between the clinical course and CT findings. Given the improvement of the patient's condition with conservative treatment with ampicillin/sulbactam, the CT findings suggested an apparent abscess due to increased esophageal wall thickness. However, MR diffusion-weighted images showed a slightly high-intensity signal, suggesting that the enlargement was due to edema rather than an abscess. The patient recovered successfully following conservative treatment. Thus, our findings demonstrate the utility of MRI in the treatment planning of acute phlegmonous esophagitis, especially in cases with unreliable contrast-enhanced CT findings. However, future studies are warranted to explore the utility of MRI in the management of such cases.

Laparoscopic intervention for solid pelvic tumours in Mayer-Rokitansky-Küster-Hauser syndrome: a case of bilateral uterine adenomyomas of the rudimentary uterus.

Mayer-Rokitansky-Küster-Hauser (MRKH) syndrome, a condition caused by Müllerian anomalies, is characterised by congenital vaginal aplasia and a rudimentary uterus. Case reports concerning uterine fibroids associated with MRKH syndrome are limited, and differentiating between uterine fibroids and ovarian solid tumours prior to surgical intervention is often challenging. Here, we present the case of a patient with MRKH syndrome and asymptomatic bilateral pelvic solid tumours located close to both ovaries. Based on intraoperative and histopathological findings, the tumours were diagnosed as adenomyomas of the rudimentary uterus. This is the first reported case of a uterine adenomyoma associated with MRKH syndrome. Moreover, our report highlights the fact that diagnostic laparoscopy is a valuable method to evaluate pelvic tumours in MRKH syndrome.

Ureter Injury in Total Laparoscopic Hysterectomy.

Objective: To identify surgical manipulations that caused ureter injury during total laparoscopic hysterectomy (TLH) and evaluate the surgical manipulations to identify ways to prevent such injury. Patients and Methods. This single-center, cross-sectional study included 1135 cases of TLH performed for benign diseases from January 2009 to December 2021. Seven cases (0.6%) that needed ureteral stent placement intra- or postoperatively for ureter injury were included. We identified the surgical manipulations that caused ureter injury from surgical videos. Results: Two cases had adhesions around the bladder pillar, and the ureter sustained a thermal injury during the cardinal ligament transection. One case had severe endometriosis, and the ureter was bluntly damaged when the adhesion was released. In one case, the ureter was thermally damaged during bipolar hemostasis for uterine artery bleeding. In two cases, the obliterated umbilical artery was mistaken for the ureter, and the real ureter was injured. In one case, ureteral peristalsis was inhibited by a pelvic abscess caused by postoperative infection. Conclusion: To prevent ureter injury during TLH, the ureter should be isolated in case of severe adhesion. Moreover, the following could be considered: (1) expand Okabayashi's pararectal space lateral to the uterosacral ligament, (2) perform dissection sharply using a monopolar or scissors forceps when releasing adhesion, (3) clarify the anatomy around the ureter for cases needing hemostasis, (4) repeatedly confirm the ureter with its peristalsis even after its isolation, (5) for severe adhesion cases, reduce infection risk by drain placement and administering antibiotics, and (6) use a delineator cup.

Ureter Injury in Laparoscopic Para-Aortic Lymphadenectomy for Endometrial Cancer by the Transperitoneal Approach.

The patient was 66 years old, had three pregnancies and two deliveries, and was menopausal at the age of 51. She had irregular bleeding and was found to have a chicken-egg-sized uterus and a thickened endometrium (23 mm). She underwent laparoscopic surgery for uterine endometrial cancer (endometrioid carcinoma G1, stage IB). Laparoscopic simple hysterectomy, bilateral adnexectomy, pelvic lymph node dissection, para-aortic lymph node dissection, and partial omentectomy were performed using the transperitoneal approach (TPA). The patient was obese, with a height of 148 cm, a weight of 68 kg, and a body mass index of 31 kg/m2. She had a large amount of visceral fat, which made it difficult to expand the surgical field during para-aortic lymph node dissection. A laparoscopic fan retractor (EndoRetract II, Medtronic) was used to lift the intestinal tracts and expand the field of view. It broke the fat around the left kidney, and the exposed left ureter was heat-damaged using a vessel sealing device (LigaSure, Medtronic). Postoperatively, a left ureteral stent was placed, and continuous urine draining into the retroperitoneum was performed. To prevent injury to the left ureter, the left ovarian vein branching from the left renal vein should be exposed as a landmark before the left ureter running parallel to it is isolated. It is essential that the fat around the left kidney is not broken during this operation. The left iliopsoas muscle should be exposed, and using this as a base, the left ovarian vein, left ureter, and left perirenal fat should be compressed and moved to the left side using a fan retractor to ensure a safe operation.

A case of problems in supporting a patient after Y-chromosome long arm microdeletion testing at a Japanese general hospital.

There are only few reports on the problems faced post-Y-chromosome microdeletion tests that decide the use of micro testicular sperm extraction. We report a case wherein we faced issues in supporting a patient post-testing. One patient with azoospermia factor c (AZFc) deletion gave birth to a baby boy, who could have inherited the AZFc deletion; however, we could not inform the young patient. Therefore, it is necessary to establish a post-testing support system for patients and infants.

Gastrointestinal Stromal Tumor with Repeated Multiple Cerebral Infarction Mimicking Ovarian Cancer with Trousseau's Syndrome.

We report a case of gastrointestinal stromal tumor (GIST) with repeated multiple cerebral infarctions mimicking ovarian cancer. A 79-year-old postmenopausal woman had multiple cerebral infarctions with a giant pelvic tumor detected by computed tomography. Ovarian cancer with Trousseau's syndrome was suspected. Through laparoscopic biopsy on the tumor surface, she was diagnosed with left ovarian fibrosarcoma; although, the abdominal cavity could not be observed appropriately. Ovarian fibrosarcoma is an extremely rare tumor and still has no adequate treatment strategy. Complete resection was planned. The tumor was extremely fragile, and gelatinous that it easily bled. Meanwhile, the uterus and bilateral ovaries and fallopian tubes were all normal. The tumor invaded only the peritoneum near the left sacral uterine ligament and sigmoid colon, with no peritoneal dissemination. To completely remove the tumor, we performed total hysterectomy with bilateral salpingo-oophorectomy and omentectomy and sigmoidal and rectal resection with colostomy. Despite resuming her anticoagulant therapy on postoperative day 4, she had recurrent multiple strokes. On histopathological examination, tumor showed spindle cell proliferation with severe atypia, increased mitotic activity, and widespread necrosis. Immunohistochemical studies showed positive staining for c-kit, CD34, and DOG1. Thus, she was diagnosed with GIST. This case was rare and highly malignant, with a high risk of recurrence of GIST because of a giant ruptured tumor that had a mitotic activity of 36/10 high-power fields from the sigmoid colon. Multiple cerebral infarctions mimicking ovarian cancer recurred. Therefore, preoperative diagnosis of an atypical GIST was extremely difficult.

A randomized, double-blind, placebo-controlled, dose-escalating phase I trial to evaluate safety and immunogenicity of a plant-produced, bivalent, recombinant norovirus-like particle vaccine.

Noroviruses (NoV) are the leading cause of epidemic acute gastroenteritis in humans worldwide and a safe and effective vaccine is needed. Here, a phase I, double-blind, placebo-controlled clinical trial was performed in 60 healthy adults, 18 to 40 years old. Safety (primary objective) and immunogenicity (secondary and exploratory objectives) of a bivalent (GI.4 and GII.4), plant-produced, virus-like particle (VLP), NoV vaccine candidate formulation were investigated at two dose levels (50 µg + 50 µg and 150 µg + 150 µg) without adjuvant. Overall, 13 subjects (65.0%) in the 50 µg group, 16 subjects (80.0%) in the 150 µg group, and 14 subjects (70.0%) in the placebo group reported at least 1 solicited local or general symptom during the 7-day post-vaccination periods following each dose. Severe solicited adverse events (AEs) were rare (2 events in the 50 µg group). A total of 8 subjects (40.0%) in each group reported at least one unsolicited AE during the 28-day post-vaccination periods. Immunogenicity was assessed on days 1, 8, 29, 57, 183 and 365. All subjects were pre-exposed to norovirus as indicated by baseline levels of the different immunological parameters examined. Vaccine-specific humoral and cellular immune responses increased after the first dose but did not rise further after the second vaccination. Increased GI.4- and GII.4-specific IgG titers persisted until day 365. The vaccine elicited cross-reactive IgG antibodies against non-vaccine NoV VLPs, which was more pronounced for NoV strains of the same genotype as the GII.4 vaccine strain than for non-vaccine genotypes. Significant blocking anti-GI.4 and anti-GII.4 VLP titers were triggered in both dose groups. Lymphoproliferation assays revealed strong cell-mediated immune responses that persisted until day 365. In conclusion, both dose levels were safe and well-tolerated, and no higher incidence of AEs was observed in the higher dose group. The data show that a single dose of the vaccine formulated at 50 µg of each VLP is sufficient to reach a peak immune response after 8 to 28 days. The results of this Phase I study warrant further evaluation of the non-adjuvanted vaccine candidate. Clinical trial registration: https://clinicaltrials.gov/ct2/show/record/NCT05508178, identifier (NCT05508178).

The rs8099917 polymorphism, when determined by a suitable genotyping method, is a better predictor for response to pegylated alpha interferon/ribavirin therapy in Japanese patients than other single nucleotide polymorphisms associated with interleukin-28B.

We focused on determining the most accurate and convenient genotyping methods and most appropriate single nucleotide polymorphism (SNP) among four such polymorphisms associated with interleukin-28B (IL-28B) in order to design tailor-made therapy for patients with chronic hepatitis C virus (HCV) patients. First, five different methods (direct sequencing, high-resolution melting analysis [HRM], hybridization probe [HP], the InvaderPlus assay [Invader], and the TaqMan SNP genotyping assay [TaqMan]) were developed for genotyping four SNPs (rs11881222, rs8103142, rs8099917, and rs12979860) associated with IL-28B, and their accuracies were compared for 292 Japanese patients. Next, the four SNPs associated with IL-28B were genotyped by Invader for 416 additional Japanese patients, and the response to pegylated interferon/ribavirin (PEG-IFN/RBV) treatment was evaluated when the four SNPs were not in linkage disequilibrium (LD). HRM failed to genotype one of the four SNPs in five patients. In 2 of 287 patients, the results of genotyping rs8099917 by direct sequencing differed from the results of the other three methods. The HP, TaqMan, and Invader methods were accurate for determination of the SNPs associated with IL-28B. In 10 of the 708 (1.4%) patients, the four SNPs were not in LD. Eight of nine (88.9%) patients whose rs8099917 was homozygous for the major allele were virological responders, even though one or more of the other SNPs were heterozygous. The HP, TaqMan, and Invader methods were suitable to determine the SNPs associated with IL-28B. The rs8099917 polymorphism should be the best predictor for the response to the PEG-IFN/RBV treatment among Japanese chronic hepatitis C patients.

1,2-Dioleoylglycerol method for pancreatic lipase catalytic activity in serum.

BACKGROUND: There is a need for a pancreatic lipase (LIP) reference assay to provide an accurate base to which routine methods can be traceable. METHODS: This study developed a novel LIP assay method in which 1,2-dioleoylglycerol (DODG) is the substrate and LIP activity is measured in a coupled enzymatic reaction from the increase in absorbance at 340 nm with production of NADPH. RESULTS: With this method, LIP activity was linear up to 440 U/L (8-times expected upper limit of physiological concentration). When assayed manually, the between-laboratory variation for six samples surveyed at five laboratories was 3.80-26.4% (CV) for samples containing about 20-290 U/L LIP activity; when assayed using an automated analyzer, the range was 1.86-4.86% (four laboratories). Interference by >5 mmol/L glycerol and low specificity with post-heparin samples were noted, but in practice these are avoidable. Precision analyzed by automated assay of 49 samples twice in random order produced a covariance of 2.27 U/L, which is comparable to routine methods, and good correlations were obtained with five routine methods. CONCLUSIONS: Although further studies are required, the DODG method may be likely applicable as one candidate reference method.

Placental polyp with arteriovenous malformation treated with a gonadotoropin-releasing hormone antagonist.

A 35-year-old woman (gravida 1, para 0) underwent termination of pregnancy (ToP) at 12 weeks of gestation. One month after ToP, she experienced significant vaginal bleeding and the mass with blood flow was identified on imaging. The presence of a placental polyp with arteriovenous malformation (AVM) was suspected on transvaginal sonography and MRI. Since the bleeding had ceased when she visited our hospital, we decided to treat the placental polyp with AVM with gonadotropin-releasing hormone (GnRH) antagonist therapy instead of surgery. Two months after GnRH antagonist treatment, the mass and blood flow in the uterus disappeared. Menstruation resumed 1 month after the completion of treatment. In our case, we were able to successfully treat placental polyps with AVM using GnRH antagonist therapy.
