Purpose The systemic inflammation is believed to provide an outline of the association between rheumatoid arthritis (RA) and endometriosis. This retrospective cohort study aimed to explore the association of Chinese herbal medicine (CHM) use with the prevention of endometriosis onset in women diagnosed with RA. Methods We utilized the claims data from the National Health Insurance of Taiwan from 2000 to 2009 and excluded individuals diagnosed with endometriosis before being diagnosed with RA, using age at clinical diagnosis. After selection and propensity-score matching, a total of 5992 females aged ≧20 years old and with newly diagnosed RA but without endometriosis at baseline were included, which contained 2996 CHM users and 2996 non-CHM users. All of them were followed until the end of 2013 to measure the incidence of endometriosis. Results During the study period, we noticed that CHM users had a substantially lower incidence of endometriosis compared to non-CHM users (2.54 vs 5.19 per 1000 person-years). Use of CHM correlated significantly with a lower endometriosis likelihood even after adjusting for potential covariates, with the adjusted hazard ratio of 0.47 (95% confidence interval, 0.35–0.65). A longer duration of CHM use was associated with a reduction in endometriosis risk, especially in those using CHM for more than 730 days. Uses of several herbal products may be associated with a lower risk of endometriosis, like Ge-Gen, Da-Huang, Huang-Qin, Ye-Jiao-Teng, Chuan-Niu-Xi, Shu-Jing-Huo-Xue-Tang, Du-Huo-Ji-Sheng-Tang, Ge-Gen-Tang, Shao-Yao-Gan-Cao-Tang, Ping-Wei-San, Gan-Lu-Yin, and Dang-Gui-Nian-Tong-Tang. Conclusion Taken together, adding CHM to conventional therapy may reduce the incidence of endometriosis in women with RA. The therapeutic mechanisms and safety of these natural products may be a direction for future clinical studies.

The typical symptoms of patients with Alzheimer’s disease (AD) are amyloid-β (Aβ) plaques and tau hyperphosphorylation. However, recent studies show that these symptoms are not the cause of the disease but are generated after the pathogenesis. Compared with other types of dementia, AD has the obvious features of pineal gland calcification and decreased melatonin production. The pineal gland is mainly composed of pinealocytes that release melatonin and astrocytes. Astrocytes function to maintain a balanced concentration of calcium ions, provide nerve cell nutrients, and migrate nutrients in vivo. Calcium ions are among the most important neurotransmitters. Once triggered, a calcium wave can be formed between astrocytes to activate other astrocytes to transmit information. Most calcium is stored in the skeleton. Bone tissue is composed mainly of osteocytes, osteoblasts, and osteoclasts. Of these, osteocyte is a kind of astrocyte which regulates the activity of osteoclasts and osteoblasts. The pineal gland is composed mainly of astrocytes; osteocytes are also a kind of astrocyte. Therefore, we conclude that when astrocytes are gradually disabled, calcium may be lost from the bones, prompting osteoporosis. The calcium ions then released into the blood may accumulate and cause ectopic calcification in the pineal gland, which promotes the occurrence of AD. Finally, this study used aspects of drugs and hormones (bone and calcium metabolism hormones and melatonin) to infer the hypothesis, which proposes that astrocyte dysregulation promotes the long-term imbalance of calcium ions in vivo and leads to osteoporosis and AD.

Objectives: Rheumatoid arthritis (RA) was found to trigger the higher risk of dementia. Limited information, however, is available on whether the use of rehabilitation services (RS), an integral part of healthcare programs, can lessen dementia risk for RA subjects. The aim of this study was to determine the relationship of RS use to the development of dementia in RA patients. Methods: We identified 2,927 newly diagnosed patients with RA, 20-70 years of age between 1998 and 2007, from a national health insurance database. 965 patients from this sample received RS, and 1,962 patients were designated as a control group (non-RS users). Patients were followed to the end of 2012 to identify dementia incident as the end point. Cox proportional hazards regression was performed to calculate the hazard ratio (HR) of dementia risk associated with the use of RS. Results: During the study period, 388 patients with RS and 1,224 controls developed dementia, representing incidence rate of 75.46 and 115.42 per 1,000 person-years, respectively. After adjusting for potential confounders, RS was found to significantly reduce dementia risk, with the adjusted HR of 0.60 (95% confidence interval [CI] = 0.53-0.67). Those who used the high intensity of RS (≧15 courses) had the greatest benefit. Conclusions: Integrating RS into the conventional treatment may reduce the sequent risk of dementia for RA patients.

Posterior reversible encephalopathy syndrome (PRES), a rare disease is characterized by multiple neurological complications. It has been reported to be associated with the use of angiogenesis inhibitors such as sorafenib, sunitinib, pazopanib, regorafenib, and lenvatinib. We reported a case of 76-year-old woman with history of stage III hepatocellular carcinoma (HCC), who developed adverse drug reactions related to pazopanib induced PRES. Pazopanib, an angiogenesis inhibitor which inhibits the vascular endothelial growth factor (VEGF) pathway may lead to vascular endothelial damage, and these pathophysiological changes may lead to vascular leaks and brain edema. Medical staff must be aware of the possible association between angiogenesis inhibitors and the development of PRES. In patients with retroperitoneal soft-tissue sarcoma undergoing treatment with pazopanib, regular monitoring of their blood pressure and following-up brain magnetic resonance imaging (MRI) should be encouraged.

BackgroundRecent evidence suggests that the use of orthopedic manual therapy (OMT) may lessen the subsequent risk of low back pain (LBP), but this association has not been examined among pregnant women who are at higher risk of LBP. This study aims to determine whether the addition of OMT to conventional LBP treatment before pregnancy could decrease the subsequent risk of LBP during pregnancy.MethodsFrom Taiwan's National Health Insurance Research Database, we identified 68,960 women, 20–55 years of age, with first pregnancy between 2001 and 2012. We then performed a nested case-control study in which 3,846 women with newly diagnosed LBP were matched to 3,846 controls according to age and cohort entry year. Multivariate conditional logistic regression was employed to estimate the association between OMT use before pregnancy and LBP during pregnancy.ResultsOMT users had a lower risk of LBP than did non-users, with an adjusted OR of 0.86 (95% CI, 0.78–0.93). Subgroup analysis showed that women with high intensity use of OMT treatment prior to pregnancy reported the lowest level of LBP during pregnancy by nearly 30%.ConclusionThe pre-pregnancy use of OMT treatment significantly decreased LBP risk during pregnancy, especially with high-intensity use. Thus, clinicians may consider recommending OMT for pregnant women to avoid possible obstetric complications during the pregnancy.
