Symptom complexes in patients with seropositive arthralgia and in patients newly diagnosed with rheumatoid arthritis: a qualitative exploration of symptom development.

OBJECTIVE: The aim of this study was to explore symptoms and symptom development during the earliest phases of RA in patients with seropositive arthralgia and patients newly diagnosed with RA. METHODS: Interviews were conducted with 15 seropositive patients (anti-CCP positive, and often with arthralgia) and 11 newly presenting RA patients [classified according to the 2010 ACR/European League Against Rheumatism (EULAR) criteria]. Feedback procedures shared the experiences of seropositive arthralgia patients with early RA patients and vice versa. Data were analysed using thematic analysis. RESULTS: Symptoms common to both groups included joint pain, psychological distress, muscle cramps, abnormal skin sensations, stiffness, loss of motor control, weakness, fatigue and sleeping difficulties. Also, patterns of symptom evolution and the order of symptom development were described. Seropositive arthralgia patients described pain as annoying, while RA patients described how the severity of pain intensified before diagnosis, to the point where symptoms were psychologically distressing. Patients with seropositive arthralgia described reddening of the skin and burning sensations that they felt were indicative of the onset of swelling. Intense pain appeared to precede the onset of swelling for those with RA, which was often palindromic and travelled between joints until it later became persistent. CONCLUSION: This study highlights the breadth of symptoms that constitute the earliest phases of RA. Further research is needed to develop measures of symptom patterns and clusters to allow the predictive utility of symptoms to be assessed and to allow the integration of aspects of the patient's history into evidence-based investigative and management algorithms for use in primary and secondary care.

Effectiveness of Xiangsha Liujun pills on decreased digestive function in convalescent patients of coronavirus disease 2019: a randomized, double blind, placebo controlled clinical trial.

OBJECTIVE: To evaluate the effectiveness and safety of Xiangsha Liujun pills on the decreased digestive function in patients in the recovery phase of the Coronavirus disease 2019 (COVID-19). METHODS: A randomized, double blind, placebo controlled clinical trial was conducted. A total of 200 COVID-19 patients in the recovery phase were included in our study in Ezhou Hospital of Traditional Chinese Medicine. Totally 200 subjects were randomly divided into a treatment group (Xiangsha Liujun pills) and a control group (placebo), with 100 in each group. Subjects took Xiangsha Liujun pills or placebo orally three times a day for two weeks. Three visits were scheduled at week 0 (baseline), week 1 (the middle of the intervention) and week 2 (the end of the intervention) for each eligible patient. The total efficacy rates for improving the Traditional Chinese Medicine (TCM) symptoms (fatigue, poor appetite, abdominal distension and loose stools) and the disappearance rates of symptoms were observed and compared in the treatment and control groups. Adverse events were recorded during the study period. SAS 9.4 was used to analyze the data. RESULTS: A total of 200 patients were included in this study, among which 4 participants withdrew because the drugs did not work. Three patients were excluded for age. Before the treatment, there was no significant difference between the TCM symptoms scores of subjects. After 1 week of treatment, the full analysis set (FAS) showed that the efficacy rates for abdominal distension and loose stools in the treatment group were significantly higher than the control group ( 0.05). There were no significant differences in the efficacy rates for fatigue and poor appetite between the two groups (0.05). In addition, the disappearance rate of fatigue in the treatment group was significantly higher than the control group (0.05); there were no significant differences between the two groups after treatment in the rates of poor appetite, abdominal distension, and loose stools (>0.05). After 2 weeks of treatment, the efficacy rates for fatigue, poor appetite, abdominal distension, and loose stools in the treatment group were significantly higher than the control group (0.05). The disappearance rate of loose stools in the treatment group was significantly higher than the control group ( 0.05). However, there were no significant differences in the disappearance rates of fatigue, poor appetite, and abdominal distension between the two groups ( 0.05). No severe adverse events were reported by subjects during the study. CONCLUSIONS: This clinical study confirmed that Xiangsha Liujun pills can effectively improve the symptoms related to the decreased digestive function in COVID-19 convalescent patients.

Xuanbai Chengqi decoction plus Western Medicine in treatment of severe pneumonia with symptom pattern of phlegm-heat obstructing lung: a Meta-analysis.

OBJECTIVE: To evaluate the effectiveness and safety of Xuanbai Chengqi decoction (, XBCQD) plus Western Medicine (WM) in treatment of severe pneumonia with symptom pattern of phlegm-heat obstructing lung. METHODS: Randomized controlled trials (RCTs) investigating the effect of XBCQD on severe pneumonia with symptom pattern of phlegm-heat obstructing lung, were included in this study. Seven electronic databases were searched up to March 2019. Meta-analysis was conducted by Review Manager 5.3 software. Risk ratio (RR) and mean difference (MD) with 95% confidence interval (CI) were used as effect estimation. RESULTS: Eleven RCTs were included, involving 992 participants. Meta-analysis showed that XBCQD combined with WM achieved better effectiveness than WM alone in terms of total effective rate [RR = 1.23, 95%CI (1.16, 1.30)], clinical pulmonary infection score [CPIS, MD = -2.02, 95%CI (-2.42, -1.63)], acute physiology and chronic health evaluation Ⅱ [APACHEⅡ, MD = -6.81, 95% CI (-8.26, 5.37)], mechanical ventilation time [MD = -101.41, 95%CI (-140.47, -62.34)], and lactic acid content in arterial blood [MD = -2.41, 95%CI (-2.64, -2.18)]. CONCLUSION: XBCQD combined with WM had better benefit than WM alone to the patients of severe pneumonia with the symptom pattern of phlegm-heat obstructing lung. However, due to low quality of the included studies, more rigorously designed studies were required to further evaluate the effectiveness and safety of XBCQD in the treatment of severe pneumonia with symptom pattern of phlegm-heat obstructing lung.

Musculoskeletal ambulation disability symptom complex as a risk factor of incident bone fragility fracture.

OBJECTIVES: Influence of presenting musculoskeletal ambulation disability symptom complex (MADS) on occurrence of bone fragility fracture (BFF) is investigated with retrospective cohort study. METHODS: A total of 931 subjects joined in the study. Subjects were selected as bone fragility risk positive in the fracture assessment tool questionnaire. Their assumed risk factors were harvested from the medical records and X-ray pictures. They were followed up at least 8 years consecutively, and occurrence of incident BFF was set as primary endpoint. Each assumed risk factor including MADS was evaluated using Cox regression analysis. Subjects were divided into 2 groups according to presence of MADS (G-MADS and G-noMADS). Adjusted hazard ratios between the 2 groups was evaluated using Cox regression analysis. The statistical procedures were performed before and after propensity score matching (PSM) procedures in order to make parallel with assumed risk factors. RESULTS: Statistically significant risk factors within 5% were prevalent vertebral body fracture, disuse, MADS, cognitive disorder, hypertension, contracture, Parkinsonism, being female sex, hyperlipidemia, insomnia, T-score in the femoral neck ≤ -2.3, chronic kidney disease ≥ stage 2, chronic obstructive pulmonary diseases, glucocorticoid steroid administrated, and osteoarthritis in order of the adjusted hazard ratios (from highest to lowest). Adjusted hazard ratios between G-MADS and G-noMADS were 2.70 and 1.83 for before and after PSM, respectively. CONCLUSIONS: MADS demonstrated as a significant risk factor of BFF occurrence. In treating osteoporosis, fall risk should be aware of as well as bone fragility risk.

Protocol to study the effects of Traditional Chinese Medicine on patients with coronary heart disease showing phlegm-heat-stasis symptom pattern.

OBJECTIVE: To describe a protocol to assess the effects of Traditional Chinese Medicine (TCM) on patients with coronary heart disease (CHD) showing symptoms of phlegm-heat-stasis symptom pattern. METHODS: This is a single-blind randomized controlled trial that will be conducted in the First Teaching Hospital of Tianjin University of TCM and 60 patients with CHD showing phlegm-heat-stasis symptom pattern will be included. Patients will be randomly divided into either a treatment group (Qingre Huatan formulae + Western Medicine) or to a control group (conventional Western Medicine only) for 7-14 d. Primary patient outcomes will be vascular endothelial function and quality of life. Measurement data will be expressed as mean ± standard deviation using t-test analysis or repeated-measure variance analysis. Enumeration data will be expressed by cases and percentages, using χ2 analysis, and rank sum test will be used for ranked data. RESULTS: This study further verified the effectiveness and safety of Qingre Huatan formulae for the phlegm-heat-stasis syndrome pattern of CHD on the basis of previous studies on the characteristics of syndromes and medication rules. DISCUSSION: Phlegm-heat-stasis symptom pattern has become a common manifestation in CHD. Standardized Western medications together with TCM have been extensively used in China and have developed into a comprehensive treatment model. Our trial will help formulate recommendations for symptom maintenance and provide clinical evidence for the application of TCM for patients with CHD showing phlegm-heat-stasis symptom pattern.

Heterogeneity in progression of prodromal features in Parkinson's disease.

BACKGROUND: In the pre-diagnostic phase of Parkinson's disease (PD), a range of motor and non-motor symptoms can occur. However, there is considerable variability in their onset and currently little information exists on the pattern of progression of clinical features before diagnosis. METHODS: We analysed data from a survey amongst patients with PD from 11 European countries by the European Parkinson's Disease Association. They completed questions on first occurrence of 21 pre-diagnostic features. A principal component analysis (PCA) with varimax rotation was performed to determine the co-occurrence of these features. FINDINGS: 1467 patients were included. Changes in movement were the most commonly reported features up to 4 years before diagnosis. However, at five or more years before diagnosis loss of sense of smell, sleep problems, fatigue and other non-motor features had been experienced most frequently. PCA of pre-diagnostic features' duration revealed three factors with eigenvalues over Kaiser's criterion of 1: a) a neuropsychiatric factor comprised of anxiety, depression, apathy, stress, and sleep problems; b) an axial factor defined by difficulty eating and/or swallowing problems, freezing, and falls/balance problems; and c) a motor factor with additional non-motor features. Bladder/bowel problems and tremor had low factor loadings on all components. However, in those with disease duration less than 5 years the autonomic features were associated with the axial factor and tremor loaded on both the motor and psychiatric symptom factors. INTERPRETATION: The identified symptom complexes in the pre-diagnostic stage of PD may be reflective of a shared pattern of pathological disease progression.

Traditional Chinese Medicine symptom patterns in patients with colorectal carcinoma.

OBJECTIVE: To observe the symptom patterns (or syndromes) according to Traditional Chinese Medicine (TCM) theory in patients with various stages of colorectal cancer, and to observe the dynamic evolution process of these TCM patterns. METHODS: A prospective and cross-sectional questionnaire-based investigation was performed. Clinical data on TCM symptom patterns in patients with colorectal cancer in the perioperative period (210 cases) and adjuvant treatment period (160 cases) were collected. EPIData 3.1 together with frequency statistics and cluster analyses were performed to identify the TCM patterns based on symptom characteristics in patients with colorectal cancer, and to assess the dynamic changes in these patterns. RESULTS: In the perioperative period, from the first day of perioperative care to postoperative days 3, 7, and 10, the TCM pattern showed a process of dynamic change from blood deficiency to deficiency of both Qi and Yin and the pattern of dampness and hot accumulative knotting. In the adjuvant treatment period, the TCM pattern changed from Qi deficiency and Yin deficiency inner-heat with dampness to a deficiency pattern, primarily including Yin deficiency of the liver and kidney, deficiency of Qi and blood, and spleen deficiency. CONCLUSION: Our study confirmed that variations in the dynamic evolution of TCM symptom patterns exist in patients with colorectal cancer during different treatment periods. This information is of great value in the individualized management of colorectal cancer.

Traditional Chinese Medicine symptom pattern analysis for Parkinson's disease.

OBJECTIVE: To use the theory of Traditional Chinese Medicine to identify the major symptom patterns of Parkinson's disease. METHODS: Journal databases were searched for relevant articles in the last 30 years. Articles were reviewed for symptom patterns of Parkinson's disease and analyzed using frequency analysis, cluster analysis, and other methods of data extraction. RESULTS: The analyses indicated that the most frequent symptom patterns of Parkinson's disease are Yin deficiency of kidney and liver, deficiency of Qi and blood, phlegm heat and wind stirring, blood stasis and wind stirring, and deficiency of Yin and Yang. CONCLUSION: Taken together, the analyses identified the primary symptom patterns of Parkinson's disease as Yin deficiency of kidney and liver, deficiency of Qi and blood, phlegm heat and wind stirring, and blood stasis and wind stirring.

Biological Basis for the Clustering of Symptoms.

OBJECTIVES: Identification of biologic pathways of symptom clusters is necessary to develop precision therapies for distressing symptoms. This review examined extant literature evaluating relationships between biomarkers and symptom clusters in cancer survivors. DATA SOURCES: PubMed, CINAHL, Web of Science and Cochrane Library were searched using terms "biological markers" or "biomarkers" and "symptom cluster" or "symptom complex" or "multiple symptoms." CONCLUSION: Biomarkers related to inflammation (eg, cytokines) were the most studied and showed the most significant relationships with clusters of symptoms. This review suggests that clustering of symptoms related to cancer or cancer therapy is linked to immune/inflammatory pathways. IMPLICATIONS FOR NURSING PRACTICE: Understanding the etiology of symptom clusters may guide future nursing interventions for symptom management.
