HIV control inside postpartum mums: a new turbulent occasion.
A novel radiological research field pursuing comprehensive quantitative image, namely "Radiomics," gained traction along with the advancement of computational technology and artificial intelligence. This novel concept for analyzing medical images brought extensive interest to the neuro-oncology and neuroradiology research community to build a diagnostic workflow to detect clinically relevant genetic alteration of gliomas noninvasively. Although quite a few promising results were published regarding MRI-based diagnosis of isocitrate dehydrogenase (IDH) mutation in gliomas, it has become clear that an ample amount of effort is still needed to render this technology clinically applicable. At the same time, many significant insights were discovered through this research project, some of which could be "reverse engineered" to improve conventional non-radiomic MR image acquisition. In this review article, the authors aim to discuss the recent advancements and encountering issues of radiomics, how we can apply the knowledge provided by radiomics to standard clinical images, and further expected technological advances in the realm of radiomics and glioma.Obesity is a public health concern that is becoming increasingly more serious around the world. Bariatric surgery has become more prevalent due to the obesity epidemic worldwide. Sleeve gastrectomy (SG) is one of the most popular procedures which is safe and efficient. Despite all its favorable features, however, there is an increasing evidence from the literature that the long-term incidence of gastroesophageal reflux disease (GERD) is likely to represent the Achilles' heel of this procedure. Management of severe reflux after SG usually requires revisional surgery. The relationship between SG and GERD needs to be better ascertained in order to prevent related complications, such as esophageal adenocarcinoma. This review attempts to elucidate the effect of SG on GERD and the postoperative management of reflux disease according to recent literature in the hope of drawing the attention of clinicians to postoperative gastroesophageal reflux and guiding the optimal management strategy associated with this "troublesome complication".Objectives　This study aims to evaluate the differences in the cumulative benefit costs of public long-term care [LTC] insurance services, using a risk assessment scale score, which predicts incident functional disability among older people.Methods　A baseline survey was conducted in 2010 involving individuals aged 65 and above from 12 municipalities in Japan who were not eligible for public LTC insurance benefits (response rate 64.7%). Using public LTC claim records, we followed LTC service costs among 46,616 individuals over a period of about six years (up to 76 months). We used risk assessment scales to assess incident functional disability (0-48). We adopted a classical linear regression model, Tobit regression model, and linear regression with multiple imputation for missing values.Results　Overall, 7,348 (15.8%) of the participants had used LTC services during the follow-up period. 3-Methyladenine The risk assessment score for incident functional disability was positively associated with the cumulative costs of LTC services per person, length of usage period of LTC services, and proportion of people certified for long-term care/support need and for over long-term care level 2. After adjusting for confounding variables, the six-year cumulative costs of LTC services were around JPY 31.6 thousand higher per point of risk score (95% confidence interval [CI] 28.3 to 35.0). The costs were around JPY 8.9 thousand (95%CI 6.5 to 11.3) higher in the low score group (risk score ≤ 16), and JPY 75.3 thousand (95%CI 67.4 to 83.1) higher in the high score group (risk score ≥ 17). When we adopted other estimated models, the major results and trends were not largely different.Conclusions　In this study, the risk assessment scale score could estimate subsequent LTC benefit costs. Community interventions to improve and maintain variable aspects of risk assessment scores may help contribute to a reduction in public LTC benefits within municipalities.Objectives　We investigated the participation and detection rates of cervical lesions in cervical screening non-attenders offered HPV (human papillomavirus) self-sampling with cytology triage.Methods　From 2016 to 2018, HPV self-sampling was routinely offered as an option, along with cytology, to all non-attenders in Ebetsu City, Japan. The primary endpoints were ≥CIN2 and ≥CIN3 detection rates, and secondary endpoints were abnormal cytology rates and follow-up compliance.Results　Overall, recall invitations were mailed to 6,116 non-attenders, with a response rate of 15.9% (cytology 6.5%, HPV testing 9.4%). Of the responders to undergo HPV self-sampling, 11.7% had a positive result and were referred to cytology triage. Moreover, ≥CIN2 and ≥CIN3 detection rates were 1.7% and 0.9%, respectively, in the HPV self-sampling group, and 1.0% and 0.8%, respectively, in the cytology group, showing no statistically significant differences. In those who underwent cytology triage following an HPV positive test, ≥CIN2 and ≥CIN3 detection rates were 23.8% and 11.9%, respectively, which was significantly higher than those who only underwent cytology alone.Conclusion　HPV self-sampling followed by cytology triage is highly effective at detecting high grade disease in non-attenders. Thus, multi-municipality-based studies to standardize processes involving this method are warranted. Furthermore, HPV self-sampling could be a promising method for inviting non-attenders who have difficulty undergoing cervical screening in the COVID-19 pandemic era.Objectives　The proportion of Japanese women who maintain their employment during pregnancy and after delivery has been increasing. Previous studies from Western countries showed an association between the mother's occupation and birth outcomes; however, to the best of our knowledge, no epidemiological study has analyzed this association in Japan. Therefore, data from the national Vital Statistics Occupational and Industrial Aspects were used to examine the association between the mother's occupation and (1) the risk of stillbirth at or after 12 weeks of gestation, and (2) the risk of infant death under 1 year of age after livebirth.Methods　Data from the Vital Statistics Occupational and Industrial Aspects (Live Birth Form, and Foetal Death Form) for fiscal years (FYs) 1995, 2000, 2005, 2010, and 2015 and Vital Statistics data files (Death Form) from FYs 1995-96, 2000-01, 2005-06, 2010-11, and 2015-16 were analyzed. The study population consisted of (1) 5,355,881 infants who were born during the survey period,1.24 (1.20-1.29), 1.48 (1.41-1.56), 1.76 (1.69-1.83), 1.54 (1.46-1.61), and 0.95 (0.92-0.98), respectively. There was no association between the mother's occupation and infant deaths. link2 The PAR values for stillbirth among mothers employed as clerical workers and service workers were 7.4% and 12.3%.Conclusion　The risk of stillbirth differed according to the mother's occupation in our study. The OR and PAR of stillbirth were the highest for service workers. Mother's occupation was not associated with the risk of infant death; therefore, the mothers' occupation is likely to affect the children's condition only during pregnancy. Our study suggests the importance of understanding the causal linkage between pregnant women's occupation and birth outcomes.Objectives　In addition to physical independence such as ADLs, higher-level functional capacity ("instrumental self-maintenance," "intellectual activity," and "social role") are necessary to lead the final stage of life as independently and for as long as possible. Accordingly, in a long-term follow-up study of the local population, we examined the association of health status (total mortality and incidence of care needs) with instrumental independence, intellectual activity, and social role.Methods　We used participant data from the Kamogawa cohort study, which included surveyed use of health service, health status, disease prevalence, and use of long-term care insurance service for Kamogawa citizens in Chiba prefecture from 2003 to 2013. We compared the differences in lifestyle and higher-level functional capacity, by status of death and using the Long-term Care Insurance service. Higher-level functional capacity was assessed with the Tokyo Metropolitan Institute of Gerontology-Index of Competence (TMIG-IC); lusion　Higher-level functional capacity ("instrumental self-maintenance," "intellectual activity," and "social role") was significantly associated with total mortality and incidence of care needs.The cytotoxic T-lymphocyte antigen-4 and programmed cell death 1 pathways are novel therapeutic targets in immune checkpoint inhibitor (ICI) therapy for cancer. However, they may cause endocrine-related adverse events, including hypophysitis, autoimmune thyroiditis and type 1 diabetes mellitus (DM). link3 Moreover, delayed immune-related adverse events (irAEs) after discontinuation of ICI therapy have been reported. Here we report a 60-year-old female patient with advanced renal cell carcinoma with brain metastasis who was treated with nivolumab, ipilimumab and prednisolone. At the 3rd course of combination therapy, the administration was discontinued due to the onset of colitis and the dosage of prednisolone was increased. About half a year after discontinuation, she was admitted to the hospital with general malaise, hyperglycemia (330 mg/dL) and diabetic ketoacidosis. Glycated hemoglobin level was 6.5%. Islet-related autoantibodies were negative. The glucagon tolerance test showed complete depletion of insulin. Therefore, we diagnosed fulminant type 1 DM and treated with multiple daily injections of insulin. The onset of type 1 DM was rapid in many cases treated with combination therapy of ICIs. The present case is a rare case in which fulminant type 1 DM developed about half a year after discontinuation of nivolumab and ipilimumab. The literature shows two cases of type 1 DM occurring 4 months after discontinuation of ICI therapy by nivolumab or atezolizumab. The present case indicates that regular monitoring is mandatory for fulminant type 1 DM and other delayed irAEs after discontinuation of ICI therapy even under the low-dose prednisolone treatment.In insulin-resistant states such as obesity, pancreatic β-cells proliferate to prevent blood glucose elevations. Failure of this β-cells proliferative response leads to the development of diabetes. On the other hand, when organs are damaged, cells proliferate to repair the organs. Therefore, these proliferations are compensatory mechanisms aimed at maintaining whole-body homeostasis. We previously discovered vagal signal-mediated systems regulating adaptive proliferation of β-cells and hepatocytes. Neuron-mediated liver-β-cell inter-organ crosstalk is involved in promotion of β-cell proliferation during obesity, and in this system, vagal signals directly stimulate β-cell proliferation. Meanwhile, in the liver, the multi-step mechanisms whereby vagal nerve signals activate hepatic resident macrophages are involved in hepatocyte proliferation after severe injury. Diabetes mellitus develops on the pathological basis of insufficient insulin action. Insulin action insufficiency is attributable to insulin resistance, i.
