Exploring the Effectiveness of Biological Therapy in Patients with Psoriasis: Body Image and Quality of Life.

Background and Objectives: Psoriasis is a chronic, long-term, incurable skin inflammatory disease characterized by the excessive proliferation of epidermal keratinocytes, dilation of blood vessels, thickening of the skin, and the formation of visible red patches of variable sizes. The impact on patients differs with the severity of the disease, leading to physiological discomfort and psychological distress, which significantly affect the quality of life. The etiology of psoriasis is not completely clear, but immune cells, including type 1 and type 17 cytokine-producing cells modulated by regulatory T cells (Tregs), play a critical role in driving the disease pathogenesis. With the ability to specifically target inflammatory markers, biologics can efficiently inhibit the spread of inflammation to achieve therapeutic effects. The goal was to explore the changes in body image and quality of life in psoriasis patients undertaking therapies with biologic agents. Materials and Methods: This study employed a quasi-experimental, single-sample, pretest-posttest design. Forty-four psoriasis patients were recruited from the dermatology outpatient clinics at two medical centers in northern Taiwan. A structured questionnaire, including demographic information, the Body Image Scale (BIS), and the Dermatology Life Quality Index (DLQI), was used as a research tool. Questionnaire assessments were conducted both before and three months after the biologic agent intervention. Statistical analyses were performed using SPSS version 22.0. Results: Our results indicated a significant difference in body image between psoriasis patients before and after intervention with biologic agents. In addition, overall quality of life (QoL) also showed significant improvements before and after biologic agent intervention. There was a positive correlation between body image and quality of life in psoriasis patients. Conclusions: The treatment for psoriasis has evolved rapidly in recent years, and biologic agents have proven to be effective therapies to improve the quality of life for psoriasis patients. Our study suggests that health-related education and psychological support can further benefit psoriasis patients to willingly and positively undertake treatment and therefore improve their positive body image and quality of life.

N-Acetylcysteine Alleviates the Progression of Chronic Kidney Disease: A Three-Year Cohort Study.

Background and Objectives: The prevalence of chronic kidney disease (CKD) is approximately 10% of the population in many countries. CKD progresses to end-stage renal disease (ESRD), resulting in adverse outcomes, prolonged hospitalization, and increased healthcare costs. Therefore, reducing CKD progression to ESRD is recognized as an important health issue. Materials and Methods: Data from the study participants with stage 3 to stage 5 CKD (n = 7668) were collected from the National Health Insurance (NHI) program in Taiwan (1 November 2014 to 31 December 2020). CKD patients who had ingested or not ingested N-acetylcysteine (NAC) for three years were divided into the study group (NAC users; n = 165) and the control group (NAC non-users; n = 165) to explore whether NAC use could alleviate CKD progression and reduce the risks associated with hemodialysis in CKD patients. Results: The levels of serum creatinine (SCr) and estimated globular filtration rate (eGFR) were nearly unchanged and/or slightly changed in NAC users, but the SCr levels were slightly increased, and the eGFR levels were significantly decreased in NAC non-users at the six-month interval during the three years. A statistical difference was observed between the two groups for both levels from 12 months to 36 months. The incidence rate of hemodialysis was significantly lower in NAC users than in non-NAC users (4.8% vs. 12.7%, Wald test = 5.947, p = 0.015, OR = 34.9). These results indicated that NAC use may improve renal function of CKD patients by modulating SCr and eGFR and, in turn, reducing the risk of hemodialysis. Conclusions: We investigated whether NAC could be used to reduce CKD progression to ESRD. For the three-year retrospective study, the incidence rate of hemodialysis was significantly lower in NAC users than in non-NAC users via modulating SCr and eGRF levels. NAC use might be a useful clinical approach for reducing CKD progression to ESRD.

Chewing Gum May Alleviate Degree of Thirst in Patients on Hemodialysis.

Background and Objectives: Fluid restriction commonly causes dry mouth in patients on hemodialysis (HD). The observed effects of chewing gum on the amount of saliva, interdialytic weight gain (IDWG), and degree of thirst in patients on HD have been inconsistent. We investigated whether chewing gum can modulate these three parameters in patients on HD. Materials and Methods: We used purposive sampling to enroll 37 patients on HD who were then randomly divided into the chewing gum group (n = 19) and the control (non-chewing gum) group (n = 18). The degree of thirst was assessed using a self-rated visual analog scale (VAS) and a summated xerostomia inventory (SXI), respectively. Results: The degree of thirst after dialysis was significantly lower in the chewing gum group than in the control group. The amount of saliva was higher in the chewing gum group than in the control group before dialysis, but the saliva amount was comparable between the groups after dialysis. Furthermore, the amount of saliva was not associated with IDWG in patients on HD before or after dialysis. Conclusions: Chewing gum may alleviate the feeling of thirst but may not affect the amount of saliva and IDWG in patients on HD. Therefore, we suggest that chewing gum may be a useful approach to improve dry mouth and thirst in patients on HD.

Small Airway Dysfunction Measured by Impulse Oscillometry and Fractional Exhaled Nitric Oxide Is Associated With Asthma Control in Children.

Background: Impulse oscillometry (IOS) and fractional exhaled nitric oxide (FeNO) are sensitive and non-invasive methods to measure airway resistance and inflammation, although there are limited population-based studies using IOS and FeNO to predict asthma control. Objective: This study aimed to investigate the utility of IOS and FeNO for assessing childhood asthma control in terms of small airway dysfunction and airway inflammation. Methods: This prospective observational cohort study enrolled 5,018 school children (aged 6-12 years), including 560 asthmatic children and 140 normal participants. FeNO, spirometry, IOS, bronchial dilation test, total IgE, and childhood asthma control test (C-ACT) were measured. FeNO, IOS, spirometry, and C-ACT results were correlated with childhood asthma with and without control. Results: Uncontrolled asthmatic children had abnormal FeNO, IOS, and spirometric values compared with control subjects (P < 0.05). IOS parameters with R5, R5-R20, X5, Ax, △R5, and FeNO can predict lower C-ACT scales by the areas under receiver operating characteristic curves (AUCs) (0.616, 0.625, 0.609, 0.622, 0.625, and 0.714). A combination of FeNO (>20 ppb) with IOS measure significantly increased the specificity for predicting uncontrolled asthma patients compared with FeNO alone (P < 0.01). A multiple regression model showed that small airway parameter (R5-R20) was the strongest risk factor [OR (95% CI): 87.26 (7.67-993.31)] for uncontrolled asthma patients. Poor control with lower C-ACT scales correlated with high FeNO (r = -0.394), R5 (r = -0.106), and R5-R20 (r = -0.129) in asthmatic children (P < 0.05). Conclusion: A combined use of FeNO and IOS measurements strongly predicts childhood asthma with or without control.

Omega-3 Fatty Acids Improve Chronic Kidney Disease-Associated Pruritus and Inflammation.

Background and Objectives: Chronic kidney disease-associated pruritus (CKD-aP) is a common symptom in hemodialysis patients. A frequent and intense itching sensation largely torments patients, impacts quality of life outcomes, and it has an independent association with mortality. The objective of this study is to investigate the effects of oral supplementation with omega-3 polyunsaturated fatty acid (omega-3 PUFA) on circulating interleukin-6 (IL-6), cardiometabolic parameters, skin moisturization, and the consequent symptoms of pruritus in hemodialysis patients. Materials and Methods: Volunteers on maintenance hemodialysis with very severe pruritus symptoms were enrolled in this prospective cohort study. Subjects were instructed to consume 1000 mg fish oil once daily for 3 months. Pruritus scoring, skin moisture, plasma IL-6, and cardiometabolic parameters were measured at baseline, and at the first, second, and third month post-supplementation with fish oil for assessment of the clinical significance. Results: A total of 27 patients who had a mean age of 67.33 ± 11.06 years and 3.98 ± 3.23 years on hemodialysis completed the study. Supplementation with omega-3 PUFA significantly decreased IL-6 levels (p < 0.001), but increased the levels of c-reactive protein (CRP) (p < 0.05). Evaluation of the cardiovascular risk showed significant (all p < 0.001) decreases in the total cholesterol (CHO), low-density lipoprotein (LDL), and triglycerides (TG) levels, and an increase in the high-density lipoprotein (HDL) level. A significant decrease in plasma creatinine (CR) was observed (p < 0.001), but the decrease was limited. Supplementation with omega-3 PUFA significantly improved (all p < 0.001) skin hydration on both the face and arms, as well as disease-related symptoms of pruritus. Conclusion: Omega-3 PUFA supplementation improved inflammation, renal function, cardiovascular parameters, dry skin conditions, and the consequent symptoms of pruritus in hemodialysis patients.

Parecoxib Reduced Postsurgical Pain and Facilitated Movement More Than Patient Controlled Analgesia.

Background: Postoperative pain management is an imperative issue for patients undergoing lumbar spinal fusion surgery. Delayed pain relief is associated with poor clinical outcomes. This study compared the effects of intravenously administered patient-controlled analgesia (PCA) with intravenous parecoxib, both commonly used methods for analgesic pain control after surgery. Methods: A non-randomized study was used to recruit 68 patients who were scheduled to receive lumbar spinal fusion surgery at a hospital in Taiwan from April through December of 2020. The group treated with parecoxib received an initial perioperative dose of parecoxib 40 mg during a 30-min period and then postoperative intravenous parecoxib at 40 mg per 12-h period, for 72 h. Those with PCA received morphine (0.4 mg/ml), droperidol (0.02 mg/ml), diphenhydramine (0.48 mg/ml), midazolam (0.02 mg/ml) and saline solution during the 3-day study course. Major outcomes, including visual scale pain score and Barthel index of activities of daily living, were collected via review of medical records at 4 times: 12, 24, 48 and 72 h after surgery. Comparative effects between two groups were assessed by the generalized estimating equations. Results: After adjusting for potential confounders, the administration of parecoxib was associated with a significant decrease in pain scores and an increase in the Barthel Index, when compared with the PCA group (all p < 0.05). Notably, both effects would maintain for 72 h after surgery. Discussion: This is the first trial of which the authors are aware, that supports intravenous parecoxib as significantly enhancing patient mobility, in addition to having pain control efficacy, when compared with PCA. This study could be used as a reference when instituting interventions to improve the adaptation process and clinical prognoses after lumbar spinal fusion surgery.

Amelioration of estrogen-deficiency-induced obesity by Ocimum gratissimum.

Objectives: Menopausal transition in women initiates with declining estrogen levels and is followed by significant changes in their physiological characteristics. These changes often lead to medical conditions, such as obesity, which is correlated with chronic low-grade/subclinical inflammation. Ocimum gratissimum L. is a food spice or traditional herb in many countries; the plant is rich in antioxidants, which possess anti-inflammation activities and multitude of other therapeutic functions. Methods: In this study, we evaluated effects of O. gratissimum extract (OGE) in preventing obesity by using ovariectomized (OVX) animal models to mimic menopausal women. Methods: OVX rats showed increase in body weight and in adipocyte size in perigonadal adipose tissue (p <0.05) and decrease in uterus weight. By contrast, OGE (0.2 mg/ml) significantly reduced body weight gain and adipocyte in OVX rats and showed insignificant changes in uterus weight. Further investigation indicated that OGE exerted no influence on levels of dorsal fat, serum total cholesterol, and serum triacylglycerol and on serum biochemical factors, calcium, phosphorus, and glucose. Conclusion: These findings suggested that OGE dietary supplements may be useful in controlling body weight of menopausal women.

Amelioration of estrogen deficiency-induced obesity by collagen hydrolysate.

Objectives: Menopausal transition with declining estrogen levels significantly affects the physiological properties of women and consequently contributes to a series of medical conditions, including obesity. Obesity is a crucial risk factor associated with cardiovascular diseases, diabetes mellitus, and breast cancer. Increasing dietary protein content improves satiety and energy expenditure. Thus, we hypothesize that supplementing with collagen, a common dietary protein, may alleviate menopause-induced obesity. Methods: We used ovariectomized (OVX) rats to mimic a menopausal human. The body weight of OVX rats significantly increased compared with that of sham-operated rats (P<0.05), but uterus weight was decreased. Adipocyte size in perigonadal adipose tissue also increased (P<0.05). Results: By contrast, OVX rats supplemented with aqueous collagen hydrolysate (2.5 mg/mL) exhibited significant attenuation in body weight gain and adipocyte enlargement (P<0.05), but insignificant change in uterus weight. Further investigation indicated that collagen hydrolysate supplementation insignificantly affected the levels of dorsal fat, serum total cholesterol, and serum triacylglycerol. Levels of serum biochemical factors, calcium, phosphorus, and glucose were also insignificantly altered by collagen hydrolysate supplementation. Conclusion: Collagen hydrolysate supplementation reduced body weight gain and adipocyte enlargement in response to ovariectomy but slightly affected blood lipids, calcium, and glucose in both sham-operated and OVX rats. Collagen hydrolysate supplementation is beneficial in ameliorating estrogen deficiency-induced obesity and its associated risk factors.

Expression levels of estrogen receptor α mRNA in peripheral blood cells are an independent biomarker for postmenopausal osteoporosis.

BACKGROUND: The up- and down-regulation of the osteoclastogenesis response depends on the estrogen/estrogen receptor (ER) signaling pathway. Previous reports have shown that the promoter hypermethylation and gene polymorphism of ERα are risks for menopausal osteoporosis. No previous study has evaluated the expression levels of ERα mRNA in menopausal osteoporosis using human subjects. We hypothesized that ERα mRNA expression may show less resistance to postmenopausal osteoporosis. METHODS: In this study, we enrolled 107 women older than 45 years without menstruation and classified them into control, osteopenia, and osteoporosis groups depending on their T-scores. The ERα mRNA levels in peripheral blood cells (PBCs) were analyzed via quantitative real-time reverse-transcription polymerase chain reaction (QRT-PCR), and estrogen in the serum was detected via ELISA. RESULTS: ERα mRNA levels in PBCs had a negative correlation with age and a positive correlation with estrogen and BAP in the osteopenia and osteoporosis groups, but not in the control group. Additionally, multivariate analysis showed that older age (> 55 years), and low ERα mRNA levels in PBLs (≦ 250.39 copies/µg DNA) were associated with an approximately 9.188-, and 31.25-fold risk of osteoporosis. CONCLUSION: We conclude that ERα mRNA levels in PBLs could be used as an independent risk factor for postmenopausal osteoporosis. GENERAL SIGNIFICANCE: Our findings suggested that ERα mRNA levels in PBLs may be more important than age and serum estrogen levels.

Anemone altaica Induces Apoptosis in Human Osteosarcoma Cells.

In the past decade, no significant improvement has been made in chemotherapy for osteosarcoma (OS). To develop improved agents against OS, we screened 70 species of medicinal plants and treated two human OS cell lines with different agent concentrations. We then examined cell viability using the MTT assay. Results showed that a candidate plant, particularly the rhizomes of Anemone altaica Fisch. ex C. A. Mey aqueous extract (AAE), suppressed the viability of HOS and U2OS cells in a concentration-dependent manner. Flow cytometry analysis revealed that AAE significantly increased the amount of cell shrinkage (Sub-G1 fragments) in HOS and U2OS cells. Moreover, AAE increased cytosolic cytochrome c and Bax, but decreased Bcl-2. The amount of cleaved caspase-3 and poly-(ADP-ribose) polymerase-1 (PARP-1) were significantly increased. AAE suppressed the growth of HOS and U2OS through the intrinsic apoptotic pathway. Data suggest that AAE is cytotoxic to HOS and U2OS cells and has no significant influence on human osteoblast hFOB cells. The high mRNA levels of apoptosis-related factors (PPP1R15A, SQSTM1, HSPA1B, and DDIT4) and cellular proliferation markers (SKA2 and BUB1B) were significantly altered by the AAE treatment of HOS and U2OS cells. Results show that the anticancer activity of AAE could up-regulate the expression of a cluster of genes, especially those in the apoptosis-related factor family and caspase family. Thus, AAE has great potential as a useful therapeutic drug for human OS.

Increased levels of circulating advanced glycation end-products in menopausal women with osteoporosis.

BACKGROUND: Advanced glycation end-products (AGEs) can accumulate in organs and tissues during ageing and diabetes. Increased levels of AGEs are found in the bone tissue of patients with osteoporosis. The purpose of this study was to evaluate circulating AGEs in patients with osteoporosis. METHODS: We evaluated plasma AGEs, osteoporosis-related biomarkers, and bone mass in 82 menopausal women with osteoporosis or osteopenia, 16 young women with osteopenia, and 43 healthy women without osteoporosis or osteopenia. RESULTS: Higher levels of serum AGEs were found in the osteoporosis or osteopenia group compared to healthy women (P < 0.0001). A negative correlation was observed between serum AGEs and lumbar spine bone density (BMD of lumbar spine, r = -0.249, P = 0.028; T-score of lumbar spine, r = -0.261, P = 0.021). Women with a increased level of serum AGEs (> 8.12 U/mL) had a 5.34-fold risk of osteopenia regarding lumbar spine T-score and a 3.31-fold risk of osteopenia regarding the hip T-score. CONCLUSION: Serum AGEs could be used to monitor the severity and progression of osteoporosis. An increased serum level of AGEs was associated with impaired bone formation and was a risk factor for the development of osteoporosis. Targeting AGEs may represent a novel therapeutic approach for primary or secondary osteoporosis.

Posterior instrumentation and simultaneous intertransverse approach using transforaminal cage fusion for thoracic pseudoarthrosis in ankylosing spondylitis: a case report.

BACKGROUND: Unrecognized or untreated injury in patients with ankylosing spondylitis (AS) may develop anterior column spinal pseudoarthrosis with an open wedge bone defect. The methods of surgical treatment are controversial. Combined anterior and posterior stabilizations or posterior instrumentation with osteoclasis are beneficial as shown in an existing literature review. CASE REPORT: A 36-year-old Asian man with AS sustained a motor vehicle accident 2 years before presentation. At that time, his immediate magnetic resonance imaging scan demonstrated T10-T11 bone edema and granulation tissue formation with fluid accumulation in T10-T11 disc space. He opted for conservative treatment. His back pain was then exacerbated 2 years after the accident, and he underwent three-dimensional (3D) computed tomography (CT) scan revealing a severe pseudoarthrosis with sclerotic margins across the T10 caudal end vertebra to the T11 upper end plate, with a maximal fracture gap of 15 mm. Spinal cord compression was not present. After selecting for an appropriate cage size with the aid of the preoperative 3D CT images, we used a single posterior approach to apply pedicle screws, removed pseudoarthrotic granulation tissue through an intertransverse posterior lateral approach without entering the spinal canal, and inserted a transforaminal lumbar interbody fusion (TLIF) cage with bone graft. There was radiographic evidence of spinal fusion at the 9-month follow-up, and the patient had resumed all normal daily activities. CONCLUSION: The authors found that a less invasive single posterior surgical approach using a TLIF cage and pedicle screws could be applied to AS patients with combined thoracic pseudoarthrosis and an anterior column defect. Using a TLIF cage may provide circumferential stability immediately, bone graft fusion, and sagittal plane correction simultaneously. An appropriate cage size and placement selected with preoperative 3D CT images are the keys to success.

Shikonin induces apoptosis through reactive oxygen species/extracellular signal-regulated kinase pathway in osteosarcoma cells.

Shikonin, a major ingredient in the Chinese traditional herb Lithospermum erythrorhixon, exhibits multiple biological functions including antimicrobial, anti-inflammatory, and antitumor effects. In this study, we delineated the molecular mechanisms of shikonin in the apoptosis of 143B osteosarcoma cells. Shikonin reduced the cell viability of 143B cells in a dose- and time-dependent manner. The IC(50) at 24 h and 48 h for 143B cells was 4.55 and 2.01microM, respectively. A significantly elicited hypodiploid cell population was found in cells treated with 2, 4, and 8microM shikonin for 24 h. Moreover, treatment with shikonin induced reactive oxygen species (ROS) generation, increased extracellular signal-regulated kinase (ERK) phosphorylation, decreased B-cell lymphoma-2 (Bcl2) expression, and was accompanied by poly(ADP-ribose) polymerase (PARP) cleavage. Pretreatment with the antioxidant agent N-acetyl cysteine (NAC) not only reversed shikonin-induced ROS generation but also significantly attenuated the cytotoxic effects of shikonin in 143B cells. Furthermore, NAC attenuated shikonin-induced ERK phosphorylation. Taken together, our results reveal that shikonin increased ROS generation and ERK activation, and reduced Bcl2, which consequently caused the cells to undergo apoptosis. Therefore, shikonin may be a promising chemotherapeutic agent for osteosarcoma treatment.
