Encouraging better evaluation in digital health: guidance, training and community development

Abstract Digital health have the potential to deliver effective interventions on a wide scale. However, digital health products and services need better evaluations. There are significant barriers to this. Public Health England wanted to understand and tackle pragmatically the problem of evaluating digital health. This is particularly important in the time of COVID-19, when a large number of digital interventions are being developed and introduced at pace. It assembled a multidisciplinary team including service designers, academics, and public health professionals. They employed user-centred design methods, including qualitative research, and engagement with end-users and stakeholders. They used the findings to identify opportunity areas, develop concepts, test prototypes, and plan service implementation. This work led to the Evaluating Digital Health Products resource on GOV.UK which includes practical guidance, a methods library with digital case studies, and workshop templates for teams. It is intended to help anyone developing or running a digital health intervention. This resource launched to the public in 2020 but the service is still being improved and developed. The aim of this presentation is to introduce the online resource, describe its comprehensive iterative development, and present the evaluation training models. We will also describe the immediate next steps, which include development of an evaluation community, user testing of new content, and plans for developing a sustainable workshop model.

A Case Report of Primary Angiitis of the Central Nervous System

BACKGROUND AND OBJECTIVE: Primary angiitis of the central nervous system (PACNS) is an inflammatory vasculitis with very low frequency and prevalence. It is not clear why the inflammatory process of this disease is limited to cerebrovascular disease without systemic manifestations. A case of primary angiitis of the central nervous system with cerebrovascular manifestations is reported here. CASE REPORT: The patient is a 50-year-old woman with headache, nausea, vomiting, and visual symptoms without clear motor impairment. Normocytic normochromic anemias tests and function tests of kidney, liver and thyroid and serology of infectious diseases were reported to be normal. The patient underwent brain imaging, and due to multiple lesions in both cerebral hemispheres and cerebellum, she underwent biopsy with a probable diagnosis of cerebral vasculitis. After histopathologic confirmation, the patient was discharged with glucocorticoid and cyclophosphamide therapy, and the symptoms subsided after one year follow-up. CONCLUSION: Based on the results of this case report, some general and common symptoms of the primary angiitis of the central nervous system should also be considered

The Effectiveness of Cognitive – Behavioral Group Therapy On Pain Perception And Pain Severity Among Patients With Chronic Neuropathic Pain

BACKGROUND AND OBJECTIVE: The experience of pain consists of two sensory and emotional dimensions. The sensory dimension of pain indicates pain severity and the emotional dimension indicates pain perception. Since cognitive–behavioral therapy is an evidence-based treatment and emphasizes on the correction of dysfunctional thought processes and changing the maladaptive behaviors, this study was designed to investigate the effectiveness of cognitive – behavioral group therapy on pain perception and pain severity among patients with chronic neuropathic pain. METHODS: This quasi-randomized trial was performed among 30 patients with chronic neuropathy referring to Rouhani Hospital in Babol in two groups of case and control (15 patients in each group). Cognitive – behavioral group therapy was performed in ten 120-minute sessions, held once a week for the experimental group. Participants were examined before the experiment and 45 days after the sessions, and the perception of pain was evaluated by the components of belief in pain permanence, self-blame, belief in pain constancy, mysteriousness of pain, and pain severity. The attainable score in The Pain Beliefs and Perceptions Inventory was 30 to -30, and in The West Haven-Yale Multidimensional Pain Inventory was 0 to 6. FINDINGS: The results showed that there was a statistically significant difference between the two groups in the total score of pain perception (-8.87±7.40 vs. 1.6±93.30) (p=0.001), and the subscales of belief in pain permanence (-4.13±1.76 vs. 0.93±3.30) (p=0.04), belief in pain constancy (0.80±3.16 vs. -2.13±3.50) (p=0.04), mysteriousness of pain (-2.73±3.67 vs. 1.33±3.95) (p=0.003), and pain severity (2.19±1.28 vs. 3.64±1.27) (p=0.003). CONCLUSION: The present study showed that cognitive–behavioral group therapy could be an effective intervention for reducing the pain perception and pain severity in patients with chronic neuropathic pain

The Effectiveness of Well-Being Therapy on Coping Strategies and Self-Efficacy of Patients with Chronic Neuropathic Pain

Background and Objective: Neuropathic diseases are neurodegenerative conditions and a wide and difficult group of peripheral nerve diseases in humans. Since well-being therapy emphasizes the high levels of six domains of psychological well-being, this study was conducted to investigate the effectiveness of well-being therapy on pain coping strategies and self-efficacy of patients with chronic neuropathic pain. Methods: This clinical trial was conducted on 30 chronic neuropathic patients referred to Ayatollah Rouhani hospital in Babol and a neurologist's private office in two groups of experimental and control (n=15). Well-being therapy was performed in 8 sessions of 120 minutes, once a week for the experimental group, while the control group received the routine treatment. After the follow-up period, the control group also underwent psychotherapy. Both groups completed questionnaires of pain coping strategies (Rosenstiel and Keefe, 1985) and pain self-efficacy (Nicholas, 1989) in the pre-test, post-test and follow-up (two months after the post-test) and were compared. Findings: The results showed that there was a statistically significant difference between the two experimental and control groups in the score of the subscales of pain coping strategies in distraction from pain (23.13±3.88 versus 11.47±7.34) (p<0.001), reinterpretation of pain (17.33±5.56 versus 13.0±8.65) (p=0.114), catastrophizing (10.0±6.24 versus 16.33±5.4) (p<0.001), ignoring pain (24.4±6.67 versus 12.6±5.11) (p<0.001), hoping/praying (29.13±9.97 versus 22.4±5.7) (p=0.031), self-talk (25±4.03 versus 21.2±4.79) (p=0.026), behavioral activation (20.47±4.43 versus 11.20±4.94) (p<0.001) and pain self-efficacy (43.2±9.45 versus 33.33±13.34) (p=0.027). These results were maintained in the follow-up period. Conclusion: The present study showed that wellness therapy can be an effective intervention in improving pain coping strategies and increasing pain self-efficacy in chronic neuropathic patients

Effectiveness and safety of non-steroidal anti-inflammatory drugs and opioid treatment for knee and hip osteoarthritis: network meta-analysis

OBJECTIVE: To assess the effectiveness and safety of different preparations and doses of non-steroidal anti-inflammatory drugs (NSAIDs), opioids, and paracetamol for knee and hip osteoarthritis pain and physical function to enable effective and safe use of these drugs at their lowest possible dose. DESIGN: Systematic review and network meta-analysis of randomised trials. DATA SOURCES: Cochrane Central Register of Controlled Trials (CENTRAL), Medline, Embase, regulatory agency websites, and ClinicalTrials.gov from inception to 28 June 2021. ELIGIBILITY CRITERIA FOR SELECTING STUDIES: Randomised trials published in English with ≥100 patients per group that evaluated NSAIDs, opioids, or paracetamol (acetaminophen) to treat osteoarthritis. OUTCOMES AND MEASURES: The prespecified primary outcome was pain. Physical function and safety outcomes were also assessed. REVIEW METHODS: Two reviewers independently extracted outcomes data and evaluated the risk of bias of included trials. Bayesian random effects models were used for network meta-analysis of all analyses. Effect estimates are comparisons between active treatments and oral placebo. RESULTS: 192 trials comprising 102 829 participants examined 90 different active preparations or doses (68 for NSAIDs, 19 for opioids, and three for paracetamol). Five oral preparations (diclofenac 150 mg/day, etoricoxib 60 and 90 mg/day, and rofecoxib 25 and 50 mg/day) had ≥99% probability of more pronounced treatment effects than the minimal clinically relevant reduction in pain. Topical diclofenac (70-81 and 140-160 mg/day) had ≥92.3% probability, and all opioids had ≤53% probability of more pronounced treatment effects than the minimal clinically relevant reduction in pain. 18.5%, 0%, and 83.3% of the oral NSAIDs, topical NSAIDs, and opioids, respectively, had an increased risk of dropouts due to adverse events. 29.8%, 0%, and 89.5% of oral NSAIDs, topical NSAIDs, and opioids, respectively, had an increased risk of any adverse event. Oxymorphone 80 mg/day had the highest risk of dropouts due to adverse events (51%) and any adverse event (88%). CONCLUSIONS: Etoricoxib 60 mg/day and diclofenac 150 mg/day seem to be the most effective oral NSAIDs for pain and function in patients with osteoarthritis. However, these treatments are probably not appropriate for patients with comorbidities or for long term use because of the slight increase in the risk of adverse events. Additionally, an increased risk of dropping out due to adverse events was found for diclofenac 150 mg/day. Topical diclofenac 70-81 mg/day seems to be effective and generally safer because of reduced systemic exposure and lower dose, and should be considered as first line pharmacological treatment for knee osteoarthritis. The clinical benefit of opioid treatment, regardless of preparation or dose, does not outweigh the harm it might cause in patients with osteoarthritis.

Incidence of self-reported interpersonal violence related physical injury in Iran

Background: Violence is the cause of death for 1.5 million people in a year. Objectives: Our study aimed to estimate the incidence rate of self-reported interpersonal violence related physical injury (VRPI) and its associated factors in Iran. Patients and Methods: The sample included people ranged from 15 to 64 years old who were residing in Iran. A total of 1525 clusters were selected from the whole country. Six families were selected from each cluster via a systematic random sampling method. Then, the residential units were identified and the interviewers contacted the inhabitants. In the next step, one of the family members was selected by using Kish grid method. The instrument was a researcher-made questionnaire and consisted of two sections; demographics and project related data. Face validity and content validity of our questionnaire were investigated based on expert opinions and the reliability was confirmed by a pilot study, as well. The inclusion criteria were considered for choosing the interviewers. An interviewer was assigned for each 42 participants (7 clusters). An educational seminar was held for the administrative managers (54 persons) and interviewers (230 persons) for a week. The field work was distributed among all 46 Medical Sciences universities in Iran. In each university, administrative issues were related to an executive director. Mann-Whitney U test and odds ratio were used to analyze the data with 95 confidence interval. α value was considered less than 5. Results: The frequency of VRPI among 7886 participants was 24 during the last three months. The incidence rate of interpersonal VRPI was estimated at 3.04 per 1000 population (95 CI: 2.66-3.42) during a three-month interval in Iran. The incidence was 4.72 per 1000 population (95 CI: 4.01-5.43) for males and 1.78 per 1000 population (95 CI: 1.39-2.17) for females during a three-month interval. The mean (SD) of age of the participants with and without a history of VRPI were 26.5 (7.21) and 33.05 (12.05) years, respectively (P = 0.008). Considering the participants� gender, 66.7 were males (OR = 2.66, 95 CI: 1.14-6.23). Khuzestan Province had the most VRPIs (25 of all VRPIs). Streets and roads were the places with the highest frequency of injury (50). The most frequent injured organ was the upper limb (54.17). The most prevalent type of injury was a superficial wound (50). Finally, the most common place of treatment was home (45.83). Conclusions: We determined the incidence rate of self-reported interpersonal VRPI for the first time in Iran based on a national survey. The injuries were more common among young men. We suggest consecutive national surveys with different data gathering methods and more sample sizes. © 2015, Iranian Red Crescent Medical Journal

Impaired Striatal Akt Signaling Disrupts Dopamine Homeostasis and Increases Feeding

DOI is broken and has been reportedThe prevalence of obesity has increased dramatically worldwide. The obesity epidemic begs for novel concepts and therapeutic targets that cohesively address “food-abuse” disorders. We demonstrate a molecular link between impairment of a central kinase (Akt) involved in insulin signaling induced by exposure to a high-fat (HF) diet and dysregulation of higher order circuitry involved in feeding. Dopamine (DA) rich brain structures, such as striatum, provide motivation stimuli for feeding. In these central circuitries, DA dysfunction is posited to contribute to obesity pathogenesis. We identified a mechanistic link between metabolic dysregulation and the maladaptive behaviors that potentiate weight gain. Insulin, a hormone in the periphery, also acts centrally to regulate both homeostatic and reward-based HF feeding. It regulates DA homeostasis, in part, by controlling a key element in DA clearance, the DA transporter (DAT). Upon HF feeding, nigro-striatal neurons rapidly develop insulin signaling deficiencies, causing increased HF calorie intake. Methodology/Principal Findings We show that consumption of fat-rich food impairs striatal activation of the insulin-activated signaling kinase, Akt. HF-induced Akt impairment, in turn, reduces DAT cell surface expression and function, thereby decreasing DA homeostasis and amphetamine (AMPH)-induced DA efflux. In addition, HF-mediated dysregulation of Akt signaling impairs DA-related behaviors such as (AMPH)-induced locomotion and increased caloric intake. We restored nigro-striatal Akt phosphorylation using recombinant viral vector expression technology. We observed a rescue of DAT expression in HF fed rats, which was associated with a return of locomotor responses to AMPH and normalization of HF diet-induced hyperphagia. Conclusions/Significance Acquired disruption of brain insulin action may confer risk for and/or underlie “food-abuse” disorders and the recalcitrance of obesity. This molecular model, thus, explains how even short-term exposure to “the fast food lifestyle” creates a cycle of disordered eating that cements pathological changes in DA signaling leading to weight gain and obesity.National Institutes of Health (U.S.) (grant DA14684)National Institutes of Health (U.S.) (grant DK085712

Spring cleaning as a safety risk: results of a population-based study in two consecutive years

<p>Abstract</p> <p>Background</p> <p>Spring cleaning is a popular tradition in Iran as well as in many other countries. The purpose of our study was to determine the pattern and compare the incidence of spring cleaning related injuries in Tehran, in the years 2007 and 2008.</p> <p>Methods</p> <p>In the year 2007, a household survey was performed in Tehran by random cluster sampling. The survey was repeated in May 2008 with the same clusters and starting points, but different households. The incidence of spring cleaning related injuries, the age and sex of injured person(s), the mechanism, type and cost of injuries were recorded through semi-structured interviews. The incidence rates of injuries and injuries leading to health visits (severe) according to sex and age groups were calculated. Data were analyzed using SPSS and STATA statistical softwares.</p> <p>Results</p> <p>The incidence of all and severe spring cleaning related injuries were 3.8 (3.0 - 4.8) and 1.6 (1.1-2.3) per 1000, respectively. The most common mechanisms of injuries were falls, followed by cutting and lifting heavy objects or overexertion. Falls were also the main mechanism of severe injuries. The most common injuries were open wounds, followed by superficial injuries (including contusions) and sprain and strain. Among severe injuries, the most frequent injuries were open wounds and contusions, followed by dislocations. The injuries were most common among women with an incidence of about 8.4 per 1000 in women older than 18 years of age (severe injuries: 3.4 per 1000 (2.2-5.1)).</p> <p>Conclusion</p> <p>The incidence of spring cleaning related injuries is high enough to raise concern in health system authorities. It could be estimated that about 23,927 to 38,283 persons get injured during the spring cleaning in Tehran at the beginning of every Persian new year. In addition, about 8,773-18,344 of these cases are expected to be severe enough to lead to medical attention (considering 7,975,679 as the population of Tehran at the time of study). Improving awareness of families, especially young women, regarding the scope and importance of spring cleaning safety can be suggested as the first population-based strategy to decrease the incidence of these injuries.</p

Population-based incidence of Type 2 diabetes and its associated risk factors: results from a six-year cohort study in Iran

<p>Abstract</p> <p>Background</p> <p>The Middle East is estimated to have the largest increase in prevalence of diabetes by 2030; yet there is lack of published data on the incidence of Type 2 diabetes in this region. This study aimed to estimate Type 2 diabetes incidence and its associated risk factors in an Iranian urban population.</p> <p>Methods</p> <p>Among 3307 non-diabetics ≥ 20 years (mean age 42 ± 13 years, 42% males), glucose tolerance test was performed at baseline in 1999–2001 and at two consecutive phases in 2001–2005 and 2005–2008. Diabetes and glucose tolerance status were defined according to the ADA 1997 criteria. Logistic regression was used to determine the independent variables associated with incident diabetes and their odds ratios (OR).</p> <p>Results</p> <p>After median follow-up of 6 years, 237 new cases of diabetes were ascertained corresponding to an age and sex standardized cumulative incidence of 6.4% (95%CI: 5.6–7.2) and incidence rate of 10.6 (9.2–12.1) per 1000 person years. Besides classical diabetes risk factors, female sex and low education level significantly increased risk of diabetes in age adjusted models. In full model, the independent predictors were age [OR, 95%CI: 1.2 (1.1–1.3)], family history of diabetes [1.8 (1.3–2.5)], body mass index ≥ 30 kg/m²[2.3 (1.5–3.6)], abdominal obesity [1.9 (1.4–2.6)], high triglyceride [1.4 (1.1–1.9)], Isolated impaired fasting glucose (IFG) [7.4 (3.6–15.0)], Isolated impaired glucose tolerance (IGT) [5.9 (4.2–8.4)] and combined IFG and IGT [42.2 (23.8–74.9)].</p> <p>Conclusion</p> <p>More than 1% of the Iranian urban population older than 20 years develops Type 2 diabetes each year. Combination of IFG and IGT was the strongest predictor of incident diabetes among the modifiable risk factors.</p

A novel de novo BRCA1 mutation in a Chinese woman with early onset breast cancer

Germline mutations in the two breast cancer susceptibility genes, BRCA1 and BRCA2 account for a significant portion of hereditary breast/ovarian cancer. De novo mutations such as multiple exon deletion are rarely occurred in BRCA1 and BRCA2. During our mutation screening for BRCA1/2 genes to Chinese women with risk factors for hereditary breast/ovarian cancer, we identified a novel germline mutation, consisting of a deletion from exons 1 to 12 in BRCA1 gene, in a patient diagnosed with early onset triple negative breast cancer with no family history of cancer. None of her parents carried the mutation and molecular analysis showed that this novel de novo germline mutation resulted in down-regulation of BRCA1 gene expression
