Efficacy of Herbal Medicines on Lung Function in Asthma: a systematic review and meta-analysis of randomized controlled trials.

Objectives: The present study was designed to conduct a comprehensive systematic review and meta-analysis to assess the efficacy of herbal medicines as add-on therapy on lung function in asthmatic patients. Methods: A comprehensive search of online databases was performed up to December 2021 to identify randomized controlled trials that used orally herbal preparations for asthma as add-on therapy. Studies were assessed for methodological quality using the Cochrane Collaboration's Risk of Bias tool. The main outcome was percent predicted value of forced expiratory volume (% predicted FEV1). Pooled weighted mean difference (WMD) estimate with corresponding 95% confidence interval (CI) was calculated using inverse-variance weights method while random effects meta-analysis was used, taking into account clinical and conceptual heterogeneity. Results: As a result, 1,525 studies were identified. 169 studies were reviewed in-depth and 23 studies met our systematic review inclusion criteria. Finally, nine randomized controlled trials were included in the meta-analysis. Findings indicated that use of herbal medicines in patients with asthma significantly improved % predicted FEV1 (WMD 3.73, 95% CI 1.76-5.70), with no evidence for significant heterogeneity (p = 0.56 [Q statistic], I2 = 0.0%). In subgroup analysis by age, improvement in % predicted FEV1 was higher and significant in adults (WMD 5.16; 95% CI 2.68-7.63) compared to children (WMD = 1.27; 95% CI -1.98-4.51). Sensitivity analysis showed the significant effect of herbal medicine consumption on improving FEV1 was consistently (range of summary WMDs 3.27-4.59), indicating that the meta-analysis model was robust. There was no evidence of publication bias both visually and statistically. Conclusion: Findings support, the complementary use of herbal medicines resulted in significant improvement in the lung function compared to standard treatment in asthmatic patients with no considerable adverse events. This improvement is more likely to be observed amongst adults.

Does celecoxib with sodium valproate have an augmentation effect on acute mania in bipolar disorder? A double-blind controlled clinical trial in Iran.

Inflammatory processes in the brain play a role in acute mania etiopathogenesis. There is little evidence indicating the efficacy of celecoxib adjuvant therapy in treatmenting of manic episodes of bipolar disorder. Therefore, this clinical trial aimed to assess the celecoxib effect on treating acute mania. In a double-blind, placebo-controlled trial, 58 patients meeting the criteria for acute mania were enrolled. After considering eligibility, 45 patients were included in the study and randomly divided into two groups. The first group (23 patients) received sodium valproate 400 mg/day along with celecoxib 400 mg/day, and the second group (22 patients) received sodium valproate 400 mg/day and a placebo. The subjects were evaluated by the Young Mania Rating Scale (YMRS) at the beginning of the study and 9, 18, and 28 days following the initiation of the medication. Evaluation of baseline factors indicated a significant difference in age ( P = 0.01) and psychiatric history ( P = 0.02) between the two groups. However, other factors were similar between groups ( P ≥ 0.05). Comparing the YMRS score between celecoxib and placebo groups revealed no significant difference on days 0, 9, 18, and 28. However, the YMRS score at the end of the study decreased by 16.05 ± 7.65 in the intervention group ( P < 0.001) and 12.50 ± 5.98 in controls ( P < 0.001) compared to the baseline, the trend of change was not significant between the two groups during the time of the study ( F = 0.38; P = 0.84). Although celecoxib adjuvant therapy indicated no considerable side effects, a longer treatment duration may be needed to detect its beneficial effects for treating acute mania in bipolar patients.

Herbal Therapies for Weight Gain and Metabolic Abnormalities Induced by Atypical Antipsychotics: A Review Article.

Psychosis is a state of mind that makes it difficult to determine what is real and what is not. Psychosis can have serious negative effects. Like many psychiatric phenomena, psychosis has a variety of causes, such as schizophrenia, bipolar disorder, and psychotic depression. Antipsychotic medications, psychotherapy, and social support are the most common treatments. Antipsychotic drugs reduce the symptoms of psychosis by changing brain chemistry. Based on the mechanism of action, antipsychotics have two groups, typical and atypical. Most people who take antipsychotics experience side effects. People taking typical antipsychotics tend to have higher rates of extrapyramidal side effects, but some atypical drugs, especially olanzapine, are associated with the risk of significant weight gain, diabetes, and metabolic syndrome, which, in turn, increases the risk of atherosclerotic cardiovascular disease and premature death. Physical exercise, diet regimen, psychoeducation, monotherapy, or switching to an alternative antipsychotic are strategies to correct metabolic aberrates in atypical antipsychotic users. In light of several successful studies on the use of medicinal plants to control metabolic syndrome, this article briefly reviews the studies on some herbal medications for the management of metabolic disorders associated with atypical antipsychotics and discusses probable mechanisms. Therefore, we searched the Cochrane, Scopus, PubMed, and Google Scholar databases for works published before July, 2022, on the effect of herbal medications on antipsychotic-related metabolic abnormalities in animals or humans. We recommend that some herbal medicines may be efficient for regulating the metabolic changes related to atypical antipsychotics due to their multipotential action, and more efforts should be made to make herbal drug treatments more effective. We hope this review will be a reference for research on developing herbal therapeutics for metabolic alterations in antipsychotic customers.

Three-dimensional (3D) Visualization Educational Modeling for Ophthalmology Residents' Training: Viewpoints.

Background: Three-dimensional models are used to guide residents and physicians in accessing specific anatomical areas and types of fractures and better diagnosis of anomalies. These models are useful for illuminating complex anatomical areas, such as orbit, especially limited space with sensitive access. The aim of this study was to design a three-dimensional visualization educational modeling for ophthalmology residents' training. Methods: This study is a product-oriented application that uses radiological images of anatomy, anomalies, and orbital fractures based on actual CT scans of patients. These CT scans were carefully selected from the Picture Archiving and Communication System of Ghaem Hospital of Mashhad University of Medical Sciences. Results: To produce twelve 3D models, the CT scan files were converted to 3D printer output. Then, the models were presented to residents at a training session by an ophthalmologist. These models created all major fractures associated with the orbit area and most disorders, anomalies of this area and several normal anatomical. The features of 3D models were mentioned. The strengths and weaknesses of the educational modeling, the level of satisfaction with the use of three-dimensional models, suggestions and criticisms were assessed qualitatively by the residents. Satisfaction was reported 100% by residents. Suggestions for future 3D models were presented, and the only criticism was fear of exams and grades. Conclusion: Real-size 3D modeling help to understand the spatial and mental imagery of anatomy and orbital pathology and to touch different anatomical areas creates a clear image in the minds of residents, especially in the orbit.

The effects of l-Carnitine supplementation on inflammatory markers, clinical status, and 28 days mortality in critically ill patients: A double-blind, randomized, placebo-controlled trial.

AIM: Critical ill patients experience catabolic stress, which results in a systemic inflammatory response. The inflammatory response is associated with increased complications, including infection, multi-organ dysfunction, increased length of ICU stays, and mortality. l-Carnitine supplementation may play an important role in these patients by regulating inflammatory cell function. The purpose of the present study was to investigate the effect of l-Carnitine supplementation on clinical status, inflammatory markers, and mortality rate in critically ill patients admitted to the intensive care unit (ICU). METHODS: This randomized, double-blind, placebo-controlled trial was performed on critically ill patients. Subjects were randomly assigned into placebo (n = 27) and l-Carnitine (n = 27) groups. l-Carnitine (3000 mg/day) was administered via nasogastric tube for the intervention group for 7 days, while the other group received a placebo for the same duration. Serum levels of inflammatory markers, including C-reactive protein (CRP) and interleukin-6 (IL-6) were measured. Nutritional status and the acute physiology and chronic health evaluation (APACHE) score, sequential organ failure assessment (SOFA) score, and 28-day mortality were also recorded. RESULTS: Fifty-one critically ill patients completed the study. l-Carnitine supplementation significantly reduced the levels of CRP (mean change ± SE: -34.9 ± 6.5) and IL-6 (mean change ± SE: -10.64 ± 2.16) compared to the baseline, which is both statistically significant compared with the control group (p < 0.05). The SOFA and APACHE scores were significantly reduced in the l-Carnitine group compared with the placebo group (p = 0.02 and p < 0.001, respectively). CONCLUSIONS: l-Carnitine supplementation showed beneficial effects on inflammatory and clinical outcomes of critically ill patients.

The effect of early enteral nutrition supplemented with synbiotics on lipid and glucose homeostasis in critically ill patients: A randomized controlled trial.

BACKGROUND AND AIMS: The aim of the present study was to investigate the effects of gut microbiota modulation through synbiotic supplementation on lipid and glucose homeostasis in tube-fed critically-ill adult patients. METHODS: This study is placebo-controlled, parallel, single-center, double-blind clinical trial. 42 patients were randomly distributed in placebo and synbiotic groups to receive intervention for a maximum of 14 days. Serum levels of fasting glucose, total cholesterol, and triglycerides, insulin, and free fatty acids were obtained from blood sampling at baseline and the end of the study. Also, insulin resistance was determined by homeostasis model assessment of insulin resistance (HOMA-IR). RESULT: Fasting glucose level (Day0 = 87.84 ±â€¯15.51, Day14 = 83.76 ±â€¯8.71 mg/dl, P = 0.51), fasting insulin level (Day0 = 9.46 ±â€¯7.31, Day14 = 7.97 ±â€¯5.19 mIU/L, P = 1.00), and HOMA index (Day0 = 1.89 ±â€¯1.48, Day14 = 1.72 ±â€¯1.17, P = 0.75) during the study were decreasing in both groups, but the decreases were not significant. Serum levels of total cholesterol, triglyceride, and free fatty acidsat the beginning of the study were 114.18 ±â€¯43.43 mg/dl, 146.59 ±â€¯53.99 mg/dl, 0.83 ±â€¯0.57 mmol/L, and at the end of the study were 129.10 ±â€¯39.05 mg/dl, 127.40 ±â€¯91.88 mg/dl, 0.88 ±â€¯0.77 mmol/L, respectively. None of these changes were significant either (P = 0.99, P = 0.38, P = 0.90, respectively). CONCLUSIONS: According to our findings, synbiotics supplementation in critically ill patients has no significant effect on lipid and glucose profile.

Effect of low-fat dairy products fortified with 1500IU nano encapsulated vitamin D3 on cardiometabolic indicators in adults with abdominal obesity: a total blinded randomized controlled trial.

BACKGROUND & AIMS: Vitamin D deficiency is widespread worldwide. In this study, we aimed to evaluate the effect of a nano encapsulated form of vitamin D used for fortifying low-fat dairy products (milk and yogurt) on anthropometric indices, glycemic status, and lipid profile in subjects with abdominal obesity. METHODS: In a totally (quadruple) blinded, randomized, and parallel-controlled trial, 306 individuals with abdominal obesity were randomly allocated to one of four groups: fortified low-fat yogurt (FY, 1500 IU nano encapsulated vitamin D3 per 150 g/d), non-fortified low-fat yogurt (nFY), fortified low-fat milk (FM, 1500 IU nano encapsulated vitamin D3 per 200 g/d), non-fortified low-fat milk (nFM), for 10 weeks (nFM and nFY, were considered as the control groups). Anthropometric and biochemical parameters were measured at baseline and after a ten-week trial in Mashhad, Iran. RESULTS: After the ten-week intervention, we found a significant increase in serum concentration of 25(OH)D in both the FM and FY groups compared to the respective control groups (19.10 ± 5.69 ng/mL and 20.88 ± 5.76 ng/mL respectively, p < .001). We observed a significant reduction in weight to hip ratio (p = .04) and a significant improvement in triglyceride (p < .001) and HDL-C (p = .01) only in FM group compared to nFM group. Also, we found a significant reduction in fasting serum insulin (p < .001), and a significant improvement of HOMA-IR (p < .001) and QUICKI (p < .001) in both intervention groups compared to their placebos. CONCLUSIONS: An intake of fortified dairy products containing nano-encapsulated vitamin D3 was associated with an improvement in some measures of anthropometric indices, glucose homeostasis, and lipid profiles, particularly in individuals receiving fortified milk. Hence, along with other benefits, fortification of dairy products with vitamin D may be an effective approach to improve some cardiometabolic indicators, such as insulin resistance.

Comprehensive assessment of nutritional status and nutritional-related complications in newly diagnosed esophageal cancer patients: A cross-sectional study.

BACKGROUND & AIMS: Malnutrition is prevalent in upper gastrointestinal cancer patients. The purpose of this study was a comprehensive assessment of nutritional status in newly diagnosed patients with esophageal cancer. METHODS: Newly diagnosed esophageal cancer patients were referred to a chemo-radiation referral center in Mashhad, Iran, between February 2017 to February 2019. Anthropometric indices, a Patient-Generated Subjective Global Assessment (PG-SGA) tool, body composition, dietary intake, nutritional-related complications, and laboratory tests were assessed. RESULTS: One hundred and eighty-nine patients with a mean age of 67.1 ± 12 and a male to female ratio of 98 to 91 were included. Ninety-seven (51.3%) of patients had experienced significant weight loss and 56 (29.6%) were underweight at diagnosis. According to PG-SGA, 179 (94.7%) needed nutritional interventions. Reduced muscle mass and low handgrip strength were observed in 70 (39.4%) and 26 (14.4%) of patients, respectively. Inadequate intakes of energy (less than 24 kcal/kg/day) and protein (less than 1.2 g/kg/day) were found in 146 (77.8%) and 171 (91%) patients, respectively. The mean total daily energy and protein intakes of subjects were 943.8 ± 540 kcal/day, and 30.6 ± 21 g/day, respectively. The most common nutritional-related complications were as follows: dysphagia (84.8%), anorexia (31.6%), constipation (62.1%), esophageal pain (48.4%), and dyspepsia (41.1%). CONCLUSION: Our study demonstrated a high prevalence of malnutrition in newly diagnosed esophageal cancer patients. This fact demonstrates the importance of early screening of nutritional status via PG-SGA tool, clinical evaluation, dietary intake evaluations, and laboratory tests, based on which effective nutritional interventions and Symptoms management may be introduced in these patients.

The association between green tea consumption and breast cancer risk: A systematic review and meta-analysis.

This systematic review and meta-analysis aimed to critically evaluate the relation between green tea (GT) consumption and the risk of breast cancer. Popular electronic databases were systematically searched for papers in English language. All case-control and cohort studies in addition to randomized clinical trials were included if they assessed the chemopreventive effects of GT on breast cancer. The quality of included studies was assessed using the Newcastle-Ottawa and Jadad scale. This systematic review comprised 14 studies: 9 case-control studies, 4 cohort studies, and 1 clinical trial. Odds ratio (OR) in case-control studies suggested that women in the group receiving the highest level of GT had 19% reduction in breast cancer risk compared with those who received the lowest level of GT (summary OR = 0.81, p = .031; 95% CI [0.66, 0.981]; heterogeneity, I2  = 71.53, p < .001, random effect model; 9 studies). OR in cohort studies also showed no significant difference (OR = 0.99, p = .94; 95% CI [0.81, 1.138]; heterogeneity, I2  = 19.06, p = .29; fixed-effect model; 4 studies). According to the only clinical trial, treatment with GT could not alter the mammographic density compared with placebo (26% vs. 25%). It cannot be concluded that GT consumption may decrease the risk of breast cancer. Due to high heterogeneity, a pooled analysis of case-control and cohort studies was not performed.
