Abstract
Background The purpose of the present observational multicentric prospective study was to evaluate the efficacy and safety of a new infiltration device (CHondroGrid, Bioteck S.p.A, Arcugnano, Italy) based on hydrolyzed collagen in the treatment of rotator cuff tendinopathy. Methods Seventy-one patients (53.3 ± 11.6 years old) affected by rotator cuff tendinopathy were treated in 2021 with two subacromial injections of CHondroGrid at 13 ± 2.9 days apart. The outcomes measured were the visual analog scale (VAS) score (in movement, during the night, and at rest), the Constant Score, the Simple Shoulder Test, and patient satisfaction. The outcome variables were measured before each injection, at 1 month and at 6 months after the last injection. Results The treatment was significantly effective from the first injection and up to the six-month follow-up. At the last follow-up, the VAS score on movement had improved by 71% (P < .001), while the VAS score at rest and during the night had ameliorated by 91% and 87%, respectively (P < .001). The Constant Score and Simple Shoulder Test improved by 32% and 61%, respectively (P < .001). No adverse events were reported. Conclusions CHondroGrid resulted in a safe and effective treatment in pain relief and for the functional recovery of rotator cuff tendinopathy.

A systematic review and network meta-analysis comparing various non-pharmacological treatments for older people with mild cognitive impairment. Asian J Psychiatr 2023; 86:103635. [PMID: 37270875 DOI: 10.1016/j.ajp.2023.103635] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/05/2022] [Revised: 05/09/2023] [Accepted: 05/19/2023] [Indexed: 06/06/2023]
Abstract
BACKGROUND AND OBJECTIVE Non-pharmacological therapy appeared to alleviate Mild Cognitive Impairment (MCI) symptoms and signs, according to systematic studies. This network meta-analysis aimed to assess the impact of non-pharmacological therapies on improving cognition in individuals with MCI and identified the most effective intervention. METHODS We reviewed six databases in search of potentially relevant studies of non-pharmacological therapies such as Physical exercise (PE), Multidisciplinary intervention (MI), Musical therapy (MT), Cognitive training (CT), Cognitive stimulation (CS), Cognitive rehabilitation (CR),Art therapy (AT), general psychotherapy or interpersonal therapy (IPT), and Traditional Chinese Medicine (TCM) (such as acupuncture therapy, massage, auricular-plaster and other related systems) and others. Excluded the literature such as missing full text, missing search results, or no reporting specific values and combined with the inclusion criteria and exclusion criteria in this article, the literature ultimately included in the analysis addressed the following seven non-drug therapies PE, MI, MT, CT, CS, CR, AT. Mini-mental state evaluation paired meta-analyses were undertaken by taking weighted average mean differences with confidence intervals (CI) of 95%. The network meta-analysis was conducted to compare various therapies. RESULTS A total of 39 randomized controlled trials, including two three-arm studies, with 3157 participants were included. PE was most likely to be the most effective intervention to slow down the cognitive ability of patients (SMD = 1.34, 95%CI: 0.80, 1.89). CS and CR had no significant effect on cognitive ability. CONCLUSIONS The non-pharmacological therapy had the potential to greatly promote the cognitive ability of the adult population with MCI. PE had the best chance of being the best non-pharmacological therapy. Due to the limited sample size, substantial variability among different study designs, and the potential for bias, the results should be regarded with caution. Our findings should be confirmed by future multi-center randomized controlled, high-quality large-scale studies.

Effects of multisite anodal transcranial direct current stimulation combined with cognitive stimulation in patients with Alzheimer's disease and its neurophysiological correlates: A double-blind randomized clinical trial. Neurophysiol Clin 2022; 52:117-127. [PMID: 35339351 DOI: 10.1016/j.neucli.2022.02.003] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2021] [Revised: 02/25/2022] [Accepted: 02/28/2022] [Indexed: 01/02/2023] Open
Abstract
OBJECTIVES We aimed to examine the effects of multisite anodal transcranial direct current stimulation (tDCS) combined with cognitive stimulation (CS) over 2 months on cognitive performance and brain activity, and the relationship between them, in patients with Alzheimer's disease (AD). METHODS Patients with AD were randomly assigned to an active tDCS+CS (n=18) or a sham tDCS+CS (n=18) group. Cognitive performance was assessed using the Alzheimer Disease Assessment Scale-cognitive subscale (ADAS-cog) and brain activity using EEG (spectral power and coherence analysis) before and after the intervention. Multisite anodal tDCS (2 mA, 30 min) was applied over six brain regions [left and right dorsolateral prefrontal cortex (F3 and F4), Broca's area (F5), Wernicke's area (CP5), left and right somatosensory association cortex (P3 and P4)] for 24 sessions (three times a week). Both groups performed CS during tDCS. RESULTS Anodal tDCS+CS delays cognitive decline (ADAS-cog change) to a greater extent than sham tDCS+CS (-3.4±1.1 vs. -1.7±0.4; p=.03). Bilateral EEG coherence at high and low frequencies was greater for the active tDCS+CS than sham+CS group for most electrode pairs assessed (p < .05). The post-intervention ADAS-cog change score was predictive for EEG coherence at different sites (R²=.59 to .68; p < .05) in the active but not in the sham tDCS+CS group. CONCLUSION Anodal tDCS+CS improved overall cognitive function and changed EEG brain activity compared to sham tDCS+CS. Changes in cognitive performance were associated with changes in EEG measures of brain activity. Anodal tDCS+CS appears to be a promising therapeutic strategy to modulate cortical activity and improve cognitive function in patients with AD.

Abstract
BACKGROUND Labor pain during childbirth can have devastating effects on the progress of labor, mother, and fetus. Consequently, the management of labor pain is crucial for the well-being of the mother and fetus. Transcutaneous electrical nerve stimulation (TENS) is a non -pharmacological analgesic technique. It uses a low-voltage electrical current to activate descending inhibitory systems in the central nervous system to relieve pain. This study aimed to determine the effects of TENS therapy in the first stage of labor. METHODS In this single-blind randomized controlled trial, we screened low-risk pregnant women who anticipated spontaneous vaginal delivery. Women were assigned (1:1) to either the experimental group (received TENS therapy in the first stage of labor) or the control group (received routine obstetric care). The women, midwives, and researchers working in the gynecology and obstetric department were aware of the treatment group, but statisticians analysis the data were blinded. The primary outcome was labor pain intensity, assessed by visual analog scale (VAS) immediately after the randomization, at 30, 60, and 120 min after TENS therapy, and 2-24 h post-delivery. We used SPSS 21.0 software in data analysis. An independent sample t-test compared the mean VAS scores and labor duration between groups. A Chi-square test was employed to compare categorical variables between the groups. A significant level of ≤0.05 was statistically significant. RESULTS A total of 326 pregnant women were eligible: experimental group (n = 161) and control group (n = 165). The experimental group had statistically significantly lower mean VAS scores at a different time (30, 60, and 120 min post-intervention and 2-24 h post-delivery) than the control group (p < 0.001). The experimental group demonstrated a statistically significant shorter duration of the active labor phase than the control group (p < 0.001). CONCLUSION This study indicates that TENS can be used as a non-pharmacological therapy to reduce pain and shorten the active labor phase. TRIAL REGISTRATION ISRCTN registry, ISRCTN23857995 .

Non-pharmacological treatment of gambling disorder: a systematic review of randomized controlled trials. BMC Psychiatry 2021; 21:105. [PMID: 33596853 PMCID: PMC7888125 DOI: 10.1186/s12888-021-03097-2] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/09/2020] [Accepted: 02/05/2021] [Indexed: 11/23/2022] Open
Abstract
BACKGROUND The main focus of the non-pharmacological treatment of Gambling Disorder (GD) is the behaviour, cognition and motivation of the patient, addressing the psychological determinants of gambling. Although there is not a gold standard non-pharmacological treatment yet, many studies already had promising results, and the outcomes were even better when pharmacotherapies were combined with psychotherapies. This review intended to synthesise the efficacy of various available non-pharmacological therapies for GD evaluated in randomized controlled trials. METHODS A systematic search was conducted in PubMed and in Cochrane Library for randomized controlled trials. Studies were included if participants had GD as their primary diagnosis and excluded if patients had other comorbidities. RESULTS From 320 records identified, 22 studies were included in the critical appraisal. They included a total of 1694 patients, with a mean age of 42.94 years, and a 62.31% of males. Seven trials revealed the efficacy of cognitive behaviour therapy in improving significantly the outcomes. Three studies assessing cognitive therapy showed significant improvements in gambling symptoms, while one study showed improvements in gambling behaviour using exposure therapy. Combined or separate motivational interviewing and imaginal desensitization had significant results in 4 trials. Four other studies also showed efficacy for: couples therapy, node-link mapping therapy, 12-step facilitated and personalized feedback intervention. Physical exercise had promising results but did not reach significance. CONCLUSION The literature included in this review showed the heterogeneity of available psychotherapies. The majority of studies supported the efficacy of the tested therapies, while some of them, due to limitations such as small sample sizes or inadequate control groups, failed to reach significance.

Introducing virtual reality therapy for inpatients with dementia admitted to an acute care hospital: learnings from a pilot to pave the way to a randomized controlled trial. Pilot Feasibility Stud 2020; 6:166. [PMID: 33292729 PMCID: PMC7602317 DOI: 10.1186/s40814-020-00708-9] [Citation(s) in RCA: 10] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2020] [Accepted: 10/16/2020] [Indexed: 11/16/2022] Open
Abstract
Background Behavioural and psychological symptoms of dementia (BPSD) are difficult to manage, particularly in acute care settings. As virtual reality (VR) technology becomes increasingly accessible and affordable, there is growing interest among clinicians to evaluate VR therapy in hospitalized patients, as an alternative to administering antipsychotics/sedatives or using physical restraints associated with negative side effects. Objectives Validate and refine the proposed research protocol for a randomized controlled trial (RCT) that evaluates the impact of VR therapy on managing BPSD in acute care hospitals. Special attention was given to ascertain the processes of introducing non-pharmacological interventions in acute care hospitals. Methods Ten patients 65 years or older (mean = 87) previously diagnosed with dementia, admitted to an acute care hospital, were recruited over 3-month period into a prospective longitudinal pilot study. The intervention consisted of viewing 20-min of immersive 360° VR using a head-mounted display. Baseline and outcomes data were collected from the hospital electronic medical records, pre/post mood-state questionnaires, Neuropsychiatric Inventory (NPI) score, and standardized qualitative observations. Comprehensive process data and workflow were documented, including timestamps for each study task and detailed notes on personnel requirements and challenges encountered. Results Of 516 patients admitted during the study, 67 met the inclusion/exclusion criteria. In total, 234 calls were initiated to substitute decision makers (SDM) of the 67 patients for the consenting process. Nearly half (45.6%) of SDMs declined participation, and 40% could not be reached in time before patients being discharged, resulting in 57 eligible patients not being enrolled. Ten consented participants were enrolled and completed the study. The initial VR session averaged 53.6 min, largely due to the administration of NPI (mean = 19.5 min). Only four participants were able to respond reliably to questions. Seven participants opted for additional VR therapy sessions; of those providing feedback regarding the VR content, they wanted more varied scenery (animals, fields of flowers, holiday themes). Few sessions (4/18) encountered technical difficulties. Conclusion The pilot was instrumental in identifying issues and providing recommendations for the RCT. Screening, inclusion criteria, consenting, data collection, and interaction with SDMs and hospital staff were all processes requiring changes and optimizations. Overall, patients with dementia appear to tolerate immersive VR, and with suggested protocol alterations, it is feasible to evaluate this non-pharmacological intervention in acute care hospitals.

Long-term Follow-Up of Patients with Heart Failure and Reduced Ejection Fraction Receiving Autonomic Regulation Therapy in the ANTHEM-HF Pilot Study. Int J Cardiol 2020; 323:175-178. [PMID: 33038408 DOI: 10.1016/j.ijcard.2020.09.072] [Citation(s) in RCA: 25] [Impact Index Per Article: 6.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/01/2020] [Revised: 09/14/2020] [Accepted: 09/30/2020] [Indexed: 11/28/2022]
Abstract
BACKGROUND The ANTHEM-HF pilot study was an open-label study that evaluated the safety and feasibility of autonomic regulation therapy (ART) utilizing cervical vagus nerve stimulation (VNS) for patients with chronic HF with reduced EF (HFrEF). Patients in NYHA class II-III with EF ≤40% (n = 60) received ART for 6 months post-titration. ART was associated with sustained improvement in left ventricular (LV) function and HF symptoms at 6 and 12 months. METHODS Continuously cyclic VNS was maintained to determine longer-term safety and chronic effects of ART. Echocardiographic parameters and HF symptoms were assessed throughout a follow-up period of at least 42 months. RESULTS Between 12 and 42 months after initial titration, there were no device-related SAEs or malfunctions. There were 10 SAEs adjudicated to be unrelated to VNS, including 5 deaths. There were 6 non-serious adverse events that were adjudicated to be device-related (2 oropharyngeal pain, 1 implant site pain, 2 voice alteration, and 1 hoarseness). At 42 months, there was significant improvement from baseline in LVEF, NYHA class, 6-min walk distance, and MLHFQ score. However, these improvements at 42 months were not significantly different from mean values at 6 and 12 months. CONCLUSIONS In a 42-month follow-up, ART was durable, safe, and was associated with beneficial effects on LVEF and 6-min walk distance. Long term, chronic, open-loop ART continued to be well-tolerated in patients with HFrEF. The open label, randomized, controlled, ANTHEM-HFrEF Pivotal Study is currently underway to further evaluate ART in patients with advanced HF.

Abstract
PURPOSE The aim of this study was to investigate the effects of isometric handgrip (IHG) training on central and peripheral blood pressure (BP) and wave reflections in East Asian non-medicated middle-aged and older adults. METHODS Twenty-two men and women (mean age 65 ± 11 years) who were not actively involved in regular resistance or endurance training were randomly assigned to a group that did IHG and a control (CON) group. The IHG training was comprised of four unilateral 2-min isometric contractions at 30% of maximal voluntary contraction using a programmed handgrip dynamometer with 1-min rest periods for 5 days per week for 8 weeks. RESULTS Baseline central systolic BP (cSBP), brachial systolic BP (bSBP), brachial diastolic BP (bDBP), and the augmentation index (AIx) (via an automated applanation tonometric system) did not differ significantly between the groups. Compared to baseline, cSBP, bSBP, bDBP, and AIx decreased significantly after the 8-week study period in the IHG group (P < 0.05). No significant changes in central and peripheral BP and AIx were observed in the CON group. CONCLUSIONS These results suggest that IHG training could reduce central and peripheral BP and wave reflections in East Asian non-medicated middle-aged and older adults.

Abstract
PURPOSE Knee osteoarthritis (OA) is a musculoskeletal disorder that may have a heavy impact on the patients' quality of life. Intra-articular collagen injection may be a safe adjuvant. Recently, CHondroGrid (CG), a hydrolyzed (< 3 kDa) bovine collagen injectable formulation, has been placed on the market. The aim of this study was to investigate the safety and performance profile of CG. METHODS Patients affected by Kellgren Lawrence grade 1 to 4 knee OA and BMI < 30 were treated by administering three CG injections of 2 ml (4 mg) each (at 15 days and 45 days from the first one, respectively) and were followed up for six months after the last administration. Clinical records were retrospectively assessed to compare VAS, Lequesne and WOMAC total, pain, stiffness, and physical function scores collected at baseline and 15, 45, and 225 days after the first injection. RESULTS At the last follow-up, 70 patients (37 men and 33 women, aged 57.1 ± 14.5 years) treated with CG showed a 50% reduction in their median Lequesne score, a 50% reduction in their VAS score at rest and moving, and a ≥ 50% reduction for all other scores under consideration. CONCLUSIONS CG may be a safe and effective adjuvant in the treatment of symptomatic knee OA.

Abstract
PURPOSE To conduct a systematic review of randomized controlled trials to evaluate the evidence for the use of non-pharmacological depression therapies in older Chinese adults. MATERIALS AND METHODS The population was individuals of Chinese extraction over the age of 60 who meet the criteria for depression. The review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA). Six healthcare databases were systematically searched for publications to the end date July 2018. Included study variables were extracted and methodological quality assessments were performed. Ten studies reported sufficient data for meta-analysis. RESULTS Fifteen experimental and quasi-experimental studies fulfilled the selection criteria (N = 904 participants). Twelve studies provided sufficient data to evaluate the therapies using Effect Size (ES) (Cohen'sd); ranged from low to high. In the Qigong studies ES varied d = 0.31-0.81, Reminiscence d = 0.20-2.37, and for single studies of Tai Chi d = 1.7 and for Life Story d = 1.46. From the meta-analyses, Qigong was the only treatment that had a significant effect on the severity of depression (Z = -4.47, p < 0.01) with acceptable statistical heterogeneity between studies (I2 = 52 %). CONCLUSION Overall, there was a large methodological heterogeneity between studies attributed to differing treatments, duration and designs. Reminiscence and Life Story showed an overall effect from a range of measures, as did the exercise therapies Qigong and Tai Chi. Qigong was the only therapy having a significant effect on depression. This therapy may be useful to alleviate depression due to the group and social interaction.

Abstract
BACKGROUND Primary insomnia (PI) is one of the most common complaints among the general population. Both non-pharmacological and pharmacological therapies have proven effective in treating primary insomnia. However, the underlying mechanism of treatment remains unclear, and no studies have compared the underlying mechanisms of different treatments. METHODS In this study, we investigated gray matter volume (GMV) and resting-state functional connectivity (rsFC) changes following both pharmacological and non-pharmacological treatments in patients with PI. A total of 67 PI patients were randomized into benzodiazepine treatment, cupping treatment, or a wait-list control group for 4 weeks. The Pittsburgh Sleep Quality Index (PSQI), gray matter volume (GMV), and resting-state functional connectivity (rsFC) of the hippocampus were measured at the beginning and end of the experiment. RESULTS We found 1) significantly decreased PSQI scores in the cupping and benzodiazepine treatment groups compared to the control group with no significant differences between the two treatment groups; 2) significant GMV increases in the cupping group compared to the control group at the right hippocampus after 4 weeks of treatment; 3) significantly increased rsFC between the right hippocampus and left rostral anterior cingulate cortex/medial prefrontal cortex (rACC/mPFC) in the two treatment groups, which was significantly associated with PSQI score decreases. DISCUSSION Our findings suggest that benzodiazepine and cupping may share a common mechanism to relieve the symptoms of patients with PI.

Abstract
Depression during pregnancy has been associated with an increased risk of adverse outcomes for the infant such as preterm birth. These risks are not reduced with pharmacological treatment, but the effect of non-pharmacological therapies is unknown. We performed a systematic review to assess the risk of adverse perinatal outcomes in non-pharmacologically treated depressed women compared to non-depressed women. We found no studies that met our inclusion criteria, highlighting a critical need for research on this topic.

Abstract
We conducted a meta-analysis to summarise and quantify the effects of non-pharmacological interventions on sleep quality improvement in uraemic patients on dialysis. We defined the primary outcome as the change of sleep quality before and after interventions (evaluated by polysomonography or subjective questionnaires such as Pittsburgh sleep quality index, PSQI). The change of fatigue scales, inflammatory cytokines and adverse events were analysed as secondary outcomes. Twelve eligible randomised controlled trials and one prospective cohort study were identified. All three identified non-pharmacological interventions could result in a greater PSQI score reduction compared to controls: 1) cognitive-behavioural therapy (CBT) versus sleep hygiene education (standardised mean difference (SMD) 0.85, 95% CI 0.37-1.34); 2) physical training versus no training (SMD 3.36, 95% CI 2.16-4.57) and 3) Acupressure (including other acupoints massages) versus control (SMD 1.77, 95% CI 0.80-2.73). In terms of subscores, we found that CBT may shorten sleep latency, alleviate sleep disturbance and reduce the use of sleep medications. The finding of the cohort study suggested that intradialytic aerobic exercise training improved sleep quality in haemodialysis patients with restless leg syndrome. In conclusion, in dialysis-dependent patients, CBT could shorten sleep latency, alleviate sleep disturbance and reduce the use of sleep medications. Acupressure (including other acupoints massages) and exercise training are promising interventions but the results in these subgroups should be interpreted cautiously due to the concern of methodological quality and potential confounding factors.

Abstract
Aims Heart failure (HF) pathophysiology is believed to be mediated by autonomic dysfunction, including chronic sympathoexcitation and diminished baroreflex sensitivity, which correlate with mortality risk. Baroreflex activation therapy (BAT) is a device-based treatment providing chronic baroreflex activation through electrical stimulation of the carotid sinus. BAT chronically reduces sympathetic activity in resistant hypertension. The purpose of this investigation is to determine BAT effects in clinical HF. Methods and results In a single-centre, open-label evaluation, patients with NYHA class III HF, EF <40%, optimized medical therapy, and ineligible for cardiac resynchronization received BAT for 6 months. Efficacy was assessed with serial measurement of muscle sympathetic nerve activity (MSNA) and clinical measures of quality of life and functional capacity. Eleven patients participated in the trial. MSNA was reduced over 6 months from 45.1 ± 7.7 to 31.3 ± 8.3 bursts/min and from 67.6 ± 12.7 to 45.1 ± 11.6 bursts/100 heartbeats, decreases of 31% and 33%, respectively (P < 0.01). Concomitant improvements occurred in baroreflex sensitivity, EF, NYHA class, quality of life and 6 min hall walk (6MHW) distance (P ≤ 0.05 each). On an observational basis, hospitalization and emergency department visits for worsening HF were markedly reduced. One complication, perioperative anaemia requiring transfusion, occurred during the study. Conclusion BAT was safe and provided chronic improvement in MSNA and clinical variables. Based on present understanding of HF pathophysiology, these results suggest that BAT may improve outcome in HF by modulating autonomic balance. Prospective, randomized trials to test the hypothesis are warranted.
