- Objectives: The aim of this article is to analyze the development of integrative oncology from a bibliometric point of view. The publication and citation patterns of publications are analyzed and their contents mapped.Design: This study is based on bibliometric methods. The data sets consist of 7 025 respectively 4 990 publications over the time period 1966-2016, shown in PubMed and Web of Science.Results: The expansion of the numbers of these publications took place in the late 1990s/early 2000s. Research is dominated by authors located in the USA, China and Germany who are working at well-established research universities and university hospitals. The clinical share of publications is relatively small, and few studies are classified according to clinical phase. Content analysis revealed that much of the clinical research is based on surveys, and that content reflects the intersection of complementary therapies and cancer research. The latter aspect is less obvious in pre-clinical research. The most frequent journals in the material show a focus on complementary and alternative therapies or on integrative oncology, although journals focused on oncology or general/internal medicine were well-represented in the material as a whole. The most-cited publications were review articles and surveys.Conclusions: Integrative oncology has been established as a small, but distinct, research domain. There are several signs of specialization in integrative oncology, but also in its integration into general medical and oncological research.

- ObjectiveTo investigate if frequent stools (“diarrhoea”), infrequent stools (“constipation”), capacity in daily activities and Quality of Life (QoL) differed between patients treated with verum or sham acupuncture, and if patients with more positive treatment expectations differed regarding frequent stools and infrequent stools from patients with less positive treatment expectations.MethodsIn this randomized sham controlled trial, 200 patients received verum traditional penetrating acupuncture or sham acupuncture using a telescopic non-penetrating sham-needle 2–3 times a week during abdominal-pelvic radiotherapy (12 needling sessions during median 5 radiotherapy weeks). The patients registered stool frequency once a week, and registered capacity in daily activities and QoL at the start and end of radiotherapy, and at a one-month follow-up.ResultsIn the verum acupuncture group, 29 of 96 answering patients (30 %) experienced frequent stools and 7 (7 %) experienced infrequent stools at least one week of radiotherapy. In the sham acupuncture group, 21 of 97 (22 %) experienced frequent stools (p = 0.175) and 10 (10 %) experienced infrequent stools (p = 0.613). Patients with low treatment expectancy were more likely than other patients to experience frequent stools (60 % versus 26 %, p = 0.014) but not to experience infrequent stools (25 % versus 12 %, p = 0.334).ConclusionPenetrating acupuncture was not effective for frequent stools or for infrequent stools and did not improve capacity in daily activities or QoL in patients undergoing pelvic-abdominal irradiation for cancer more than non-penetrating acupuncture. Since patients with low acupuncture treatment expectations were more likely to experience frequent stools compared to other patients, non-specific treatment effects warrant further studies.

- A control treatment in acupuncture research must be credible, regardless if the needling is performed by one or by several therapists.Objective: To investigate if individuals could identify whether needling had been given with an acupuncture needle or a sham needle and if the therapist influenced this ability.Design: Eighty individuals were randomized to one single needling given by one of four physiotherapists using either an invasive needle or a non-penetrating telescopic sham needle.Results: An equal proportion of individuals, 27 (68%), in the acupuncture group and the sham group answered incorrectly or was not sure at all regarding needling type but the proportion varied between the therapists from 55 to 80% (ns). Bang's blinding index was 0.20 (95% CI 0.03-0.36) in the acupuncture group and 0.10 (95% CI 0.09-0.29) in the sham group (interpretation: 20 and 10% identified needling type beyond statistical chance). Acupuncture was on a four-grade scale rated as median "mildly painful" and sham as "not painful" (ns). Pain ratings varied from median "not" to "mildly painful" in the therapists (p = 0.01).Conclusions: Two thirds of individuals needled by acupuncture as well as sham could not identify needling type and only 10-20% of the individuals were unblinded beyond chance. The therapists, not the needling type, influenced how painful the needling was perceived. IMPLICATIONS: To achieve blinding success in acupuncture efficacy studies using the sham needle, the needling procedure must be strictly standardized in order to minimize differences between the therapists.

- Objective To longitudinally describe practice of Complementary and Alternative Medicine (CAM) self-care strategies for nausea during radiotherapy. Methods Two hundred patients daily registered nausea and practice of CAM self-care strategies, beside conventional antiemetic medications, for nausea during abdominal/pelvic irradiation (median five weeks) for gynecological (69%) colorectal (27%) or other tumors (4%). Results During radiotherapy, 131 (66%) experienced nausea, and 50 (25%) practiced self-care for nausea at least once, for a mean (m) of 15.9 days. The six of 50 patients who stayed free from nausea practiced self-care more frequent (m = 25.8 days) than the 44 patients experiencing nausea (m = 14.5) (p = 0.013). The CAM self-care strategies were: modifying eating (80% of all self-care practicing patients, 80% of the nauseous patients versus 83% of the patients free from nausea; ns) or drinking habits (38%, 41% vs 17%; ns), taking rests (18%, 20% vs 0%; ns), physical exercising (6%, 2% vs 33%; p = 0.035), acupressure (4%, 5% vs 0%; ns) and self-induced vomiting (2%, 2% vs 0%; ns). Conclusion A fourth of patients undergoing emetogenic radiotherapy practiced CAM self-care for nausea, mostly by modifying eating or drinking habits. The CAM self-care practicing patients who did not become nauseous practiced self-care more frequent than the nauseous patients did. To make such self-care evidence based, we need studies evaluating its efficacy. © 2017 Elsevier Ltd

- Objective: To investigate how individuals expressed rationales for their beliefs regarding efficacy of acupuncture. Methods: Qualitative data from participants of two different randomized sham-controlled trials, of relaxing (non cancer volunteers of the general population) or antiemetic (patients with cancer undergoing radiotherapy) effects of acupuncture was analyzed. Participants (n = 441) received genuine (n = 120 and n = 100) or sham (n = 121 and n = 100) (telescopic blunt sham-needle) relaxing or antiemetic acupuncture. The participants (n = 428; 97% response rate) expressed their belief regarding the efficacy of acupuncture, and n = 264 delivered qualitative rationales for their belief, analyzed using qualitative content analysis. Results: Of the 428 participants, 35 (8%) believed entirely that the acupuncture was effective, 209 (49%) believed much, 136 (32%) believed moderately, 39 (9%) believed a little, and 9 (2%) did not believe that the acupuncture was effective. Five categories and seven subcategories represented the meaning units of the central message of the rationales for the treatment belief. Participants with positive beliefs (believed entirely/much, n = 244) presented rationales related to: "Experienced positive effects", "Knowledge regarding effect-mechanisms of acupuncture", and "General trustworthiness of acupuncture". Participants with more negative beliefs (believed a little or not, n = 48) presented rationales related to: "Lack of feasibility of the acupuncture", "Varying effects", and "The effect is individual, not available for everybody". Conclusion: In order to strengthen acupuncture treated patients beliefs in the efficacy of acupuncture during clinical practice or research, acupuncture therapists may consider emphasizing these aspects in the therapeutic situation.

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: The world's elderly population is growing. Physical activity has positive effects on health and cognition, but is decreasing among the elderly. Interest in yoga-based exercises has increased in this population, especially as an intervention targeting balance, flexibility, strength, and well-being. Recent interest has arisen regarding yoga's potential benefits for cognition.OBJECTIVE: To systematically review evidence from randomized controlled trials (RCTs) examining the effects of yoga-based interventions on cognitive functioning in healthy adults aged ≥60. A secondary aim was to describe intervention characteristics and, where possible, the extent to which these influenced study outcomes.METHOD: The review was conducted in accordance with PRISMA guidelines. Searches were performed from inception to June 2020 using the following electronic databases: (1) PubMed (NLM); (2) Embase (Elsevier); (3) Cochrane Central (Wiley); (4) PsycINFO (EBSCOhost); and (5) Cinahl (EbscoHost).INCLUSION CRITERIA: RCTs of yoga-based interventions assessing cognition in healthy adults ≥60 years. Risk of bias was assessed using the revised Cochrane risk of bias tool.RESULTS: A total of 1466 records were initially identified; six studies (5 unique trials) were included in the review. Four of the six articles reported significant positive effects of yoga-based interventions on cognition, including gross memory functioning and executive functions. Intervention characteristics and assessment methods varied between studies, with a high overall risk of bias in all studies.CONCLUSION: Yoga-based interventions are associated with improvements in cognition in healthy older adults. Adequately powered RCTs with robust study designs and long-term follow-ups are required. Future studies should explicitly report the intervention characteristics associated with changes in cognitive function.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: To assess the outcome and safety of plant-based ointments versus usual care in the management of chronic skin diseases. Methods: Prospective mono-centric comparative analysis. Patients were recruited at an outpatient dermatology clinic and treated with plant-based ointments or care as usual. Main outcome criterion was the response rate, defined as the proportion of patients experiencing 'complete recovery' or 'major improvement' at 6, 12 and 24 months. Secondary outcome criteria were quality of life (SF-12 and EQ-5D), patient satisfaction and safety of treatment. Results: A total of 112 patients with chronic skin diseases were evaluated of which 44 were treated with plant-based ointments (PO) and 68 received usual care (UC). The majority of patients suffered from psoriasis (PO: 50%; UC: 56%) or eczema (PO: 41%; UC: 32%) and were treated with homoeopathic topical ointments containing mahonia or cardiospermum or usual care creams containing calcipotriene and corticosteroids. The only significant difference in baseline status between the two groups was in disease severity score (PO: 1.8 +/- 0.7 versus UC: 2.4 +/- 0.8, p=0.0004). After two years, the main outcome of responders to treatment was 52.3% (95%-CI: 36.1-64.9) in the ointment and 41.2% (95%-CI: 20.4-42.2) in the UC group. Change in SF-12 (2 years compared to baseline), adjusted for baseline disease severity, was not significantly different between both groups; PO: 5.4 (95%-CI: 3.4-7.3) versus UC: 3.2 (95%-CI: 1.5-4.9). The adjusted EQ-5D was found to be significantly different between the two groups after two years, in favour of the ointment group; PO: 0.113 (95%-CI: 0.052-0.174) and UC: -0.008 (95%-CI: -0.055-0.038). Other secondary outcome parameters such as patient satisfaction and number of adverse drug reactions were comparable. Conclusions: The outcome of this study suggests at least therapeutic equivalence between plant-based ointments and usual care management of chronic skin diseases. As this non-randomised study was open to selection and other bias, further rigorous studies are needed to demonstrate the effectiveness of these topical products. (C) 2013 Elsevier Ltd.

Tidskriftsartikel (refereegranskat)abstract
- Objective: To explore biomedical and traditional health care providers' (BHPs and THPs, respectively) perceptions of good quality of care and opinions on weaknesses in the services they provide to patients with STIs and HIV/AIDS.Methods: Using data from a cross-sectional survey, we post-coded two open-ended questions related to THPs' and BHPs' perceptions on good quality of care and on provided care. The post-coding was done following Donabedian's framework of assessment of quality of care, and allowed transformation of qualitative data into quantitative. The analysis is based on comparison of frequencies, proportions and subsequent chi-square tests and odds ratios.Setting: Ndola and Kabwe, Zambia Main measures: Proportions of responses from 152 BHPs and 144 THPs.Results: Substantial proportions of providers from both sectors perceived drugs availability (63% of BHPs and 70% of THPs) and welcoming attitude (73% of BHPs and 64% of THPs) as important components of good quality care. BHPs were more likely than THPs to mention proper examination, medical management (provider's technical ability) and explanation of causes and prognosis of the disease as important. More THPs than BHPs cited short waiting time and cost of care. A majority of BHPs (87%) and of THPs (80%) reported deficiencies in their STIs and HIV/AIDS-related services. Both groups regarded training of providers and nutritional support and health education to patients as lacking. None of the THPs alluded to voluntary counselling and testing (VCT) or supportive/home-based care as aspects needing improvement.Conclusion: Drugs availability and welcoming attitude were two aspects of quality highly valued by THPs and BHPs. Future collaborative interventions need to respond to aspects of joint concern including training of providers, nutritional support and health education to patients. Further, there is an imperative of expanding and adapting VCT, home-based care and palliative care to THPs for better care of STIs and HIV/AIDS.

Tidskriftsartikel (refereegranskat)abstract
- Objectives: The present study was initiated to determine consultations with health care providers and use of self-management strategies for prevention or treatment of COVID-19 related symptoms in countries with a full lockdown (Norway), a partial lockdown (the Netherlands) and no lockdown (Sweden) during the first three months of the COVID-19 pandemic, and if such use correlates with worries of being infected by COVID-19 disease.Design: Data were collected in collaboration with Ipsos A/S in April-June 2020. An adapted version of the International Questionnaire to measure use of Complementary and Alternative Medicine (I-CAM-Q) was used with the categories “for prevention of COVID-19” and “to treat COVID-19-related symptoms” added. Data were collected among a representative sample in Norway, Sweden and the Netherlands using data assisted telephone interviews (Norway, n=990 and Sweden, n=500), and an online survey (the Netherlands, n=1004). Total response rate was 30%.Results: Very few consulted a health care provider with the intention to treat or prevent COVID-19 (1.2% and 1.0% respectively) with medical doctors mostly visited (1.0% and 0.9% respectively). Similarly, the use of self-management strategies to prevent or treat COVID-19 was low (3.4% and 0.2% respectively); most commonly used for prevention of COVID-19 were vitamins and minerals (2.8%). Consultations with health care providers and use of self-management strategies for prevention of COVID-19 were positively associated with worries of being infected with COVID-19.Conclusions: The COVID-19 pandemic does not seem to have evoked a large-scale difference in behavior related to consultations with health care providers or the use of self-management strategies in any of the three countries.

- OBJECTIVES: We investigated the perceptions and experiences of a therapeutic yoga form, MediYoga, which is evolved from Kundaliniyoga among patients with symptomatic paroxysmal atrial fibrillation (PAF).DESIGN AND SETTING: an inductive exploratory design was chosen with individual semi-structured interviews. The study was conducted with 12 participants (7 men and 5 women, average age 63.5) at a university hospital, Sweden. Informed consent was obtained from all participants. The data were analyzed using a qualitative content analysis with an inductive method and a manifest approach.RESULTS: Three categories were found in the analysis. In the category "A time for a sense of existence and presence", the patients described an increased thoughtfulness and experiences of gaining access to an inner self. The category "A way of gaining well-being and increased consciousness" describes patients` feelings of relaxation and feeling of comfort, with components of mental and physical well-being. Furthermore, "Access to a tool to gain willpower and relieve symptoms" describes the perceptions from patients to obtained access to a tool for handling the emotions, such as fear and anxiety, as well as symptoms that they could struggling with between, and during, their episodes of atrial fibrillation. No adverse events were reported by the yoga group, during the study.CONCLUSIONS: Patients with PAF described MediYoga as an accessible tool to manage emotions and symptoms related to episodes of AF. MediYoga may also assist in enhancing body awareness, whereby physical, mental and spiritual components are integrated. MediYoga may strengthen self-management among patients with PAF.

- Objective: To compare the effects of yoga and aerobic exercise (AE) on wellbeing in physically inactive, but otherwise healthy older adults. A secondary objective was to assess and compare the frequency of adverse events associated with yoga and AE.Design: Twelve-week, three-group, parallel randomized controlled trial with blinded follow-up assessment.Interventions: Participants were supported to complete ≥ 3 Hatha yoga classes/week or ≥ 3 AE sessions/week. A wait-list control (WLC) group continued usual daily activities.Main outcome measure: Change in wellbeing, assessed using the Satisfaction with Life Scale (SWLS) and Life Satisfaction Index-Z (LSI),at baseline and at 12-week follow up.Results: In total, 82 adults (mean age 72.5 years, range 65-85, 77% female) were recruited. Of these, 27 were randomized to yoga, 29 to aerobic exercise and 26 to wait-list control. Medium-magnitude treatment effects (Hedges' g) were seen for yoga versus WLC and AE versus WLC(SWLS, g = 0.65 and 0.56; LSI, g = 0.54 and 0.54, respectively). In per-protocol analyses, larger effect sizes were found (SWLS, g = 0.72 and 0.66; LSI, g = 0.76 and 0.76, respectively). Adverse events were less frequent in the yoga group (6/27; 22%) compared to AE (10/27; 37%).Conclusions: Among physically inactive older adults, participation in yoga or AE was associated with beneficial effects on subjective wellbeing when compared to a non-active control group. Yoga was associated with fewer injuries and may be especially suitable for older adults (DRKS 00015093).

- Objective: To study nausea, vomiting and need for rescue antiemetics in patients receiving antiemetic acupuncture, sham acupuncture or standard care during concomitant chemotherapy during pelvic radiotherapy. Methods: In total, 68 patients participated (75% women, mean age 56 years, 53% had gynecological, 43% colorectal, and 4% other cancer types). Fifty-seven of them were blinded randomized to verum (n = 28) or sham (n = 29) acupuncture, median 10 sessions. During the study period of four weeks, the patients daily registered their nausea, vomiting and consumption of antiemetics. They were compared to a reference group (n = 11) receiving standard care only, who delivered these data once (after receiving mean 27 Gy radiotherapy dose). Results: More patients in the sham acupuncture group (17 of 20; 85%, p = 0.019, RR 1.81, CI 1.06-3.09) consumed antiemetics, compared to the verum acupuncture group (8 of 17; 47%). In the standard care group, 7 of 11 (63%) consumed antiemetics. The verum acupuncture treated patients experienced lower intensity of nausea than the other patients (p = 0.049). There was a non-significant tendency that more patients receiving either sham acupuncture or standard care experienced nausea (21 of 31; 68%) than patients receiving verum acupuncture (9 of 17; 53%: p = 0.074, RR 1.58, CI 0.91-2.74). Conclusion: Patients treated with verum acupuncture needed less antiemetics and experienced milder nausea than other patients. Our study was small and many analyses lacked statistical power to detect differences; we welcome further sham-controlled efficacy studies and studies regarding the role of non-specific treatment components for experiencing antiemetic effects of acupuncture.

- Introduction: Few data document the use of complementary and alternative medicine (CAM) in Europe, with even fewer investigating use by children. less thanbrgreater than less thanbrgreater thanMethods: A narrative, non-systematic review of CAM use in Europe was performed by combining data from published surveys with expert perspectives. Limitations created by a lack of representative studies, varying definitions of CAM use, and what qualifies as CAM in different countries was partially overcome by integrating local experts to summarise information available only in the national language and provide their perspectives about CAM availability, quality, use and popularity in their countries using a semi-structured questionnaire. Local and international published surveys were summarised, and the prevalence of CAM use was extrapolated. less thanbrgreater than less thanbrgreater thanResults: Data from 20 European countries were available, representing 69% of the European population. Some data about CAM use by the general population were available for 90% of the examined countries, whereas peer-reviewed published surveys were available for only 60%. We extrapolated that 56% (range: 10-90%, adjusted for population size) of the European population in general had used CAM at least once in the past year. Surveys in CAM use by children were available for 55% of the investigated countries. The extrapolated prevalence of CAM use by children in Europe was 52% (range: 5-90%, adjusted for population size). Paediatric CAM experts reported an increasing awareness for and use of CAM in healthcare institutions. less thanbrgreater than less thanbrgreater thanConclusion: This precursor for further surveys indicates that CAM appears to be popular not only among adults in Europe, but also for children. Development of a pan-European definition of CAM use and CAM therapies are required to achieve surveys comparable between European countries. Additionally, more research investigating the efficacy and potential adverse effects of CAM therapies is needed because of increasing CAM use by children in Europe.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- In this paper we present and test an alternative model for competitive capabilities.Traditionally, a cumulative model has been viewed as having one sequence of buildingoperations capabilities in a firm in support of market needs, including quality,delivery, cost efficiency and flexibility. Although appealing as a conceptual model,empirical testing has not been able to fully support the cumulative model. This paperacknowledges the need for differentiated approaches to managing capability indifferent operating environments. The competitive capability model that is presented istested empirically using data from the High Performance Manufacturing (HPM) study,including three industries and seven countries – a total of 211 plants. The results showthat there is empirical support for differentiating the competitive capabilities; firmsproducing to stock follow a path of quality, delivery and cost, whereas those producingto customer order exhibit a capability path in the order of quality, delivery andflexibility. Thus, while quality and delivery are common, cost and flexibility acts asdifferentiators contingent upon the manufacturing environment.

- Humanitarian organizations (HOs) often base their warehouse locations on individuals' experience and knowledge rather than on decision-support tools. Many HOs run separate supply chains for emergency response and ongoing operations. Based on reviews of humanitarian network design literature combined with an in-depth case study of United Nations High Commissioner for Refugees (UNHCR), this paper presents a warehouse location model for joint prepositioning that incorporates political and security situation factors. Although accessibility, co-location, security, and human resources are crucial to the practice of humanitarian operations management, such contextual factors have not been included in existing network optimization models before. We found that when quantified, and modeled, such factors are important determinants of network configuration. In addition, our results suggest that joint prepositioning for emergency response and ongoing operations allows for expansion of the global warehouse network, and reducing cost and response time.

- The paper reviews the literature on maintenance management, integrates key dimensions of maintenance within a taxonomy of maintenance configurations, and explores the impact of differing configurations on contextual factors and operational performance. 'Prevention', 'hard maintenance integration' and 'soft maintenance integration' were identifiedas key maintenance variables. Data were collected from 253 Swedish manufacturing companies, and three distinct clusters were identified. 'Proactive Maintainers' emphasized preventive maintenance policies. 'IT Maintainers' relied on computerized and company-wide integrated information systems for maintenance. 'Maintenance Laggers' emphasized all maintenance dimensions to lesser extent than the others. The importance of maintenance prevention and integration differ between contexts. There were subtle performance differences across identified configurations, but preventive and integrated maintenance were more important for companies seeking competitive process control and flexibility. There existed no group with any great emphasis on all three maintenance dimensions, but attaining truly high performance may require a rare mix ofthe three dimensions. This mix of variables could constitute a hypothesized 'World Class Maintenance' group.

- We develop actionable design propositions for collaborative sales and operations planning (S&OP) based on the observation of contexts in which benefits are generated — or are absent — from retail information sharing for a manufacturer. An information sharing pilot project in a real-life setting of two product manufacturers and one retailer was designed. The project resulted in one manufacturer, serving a retailer from its local factory, developing a process for collaborative S&OP, while the other manufacturer serving a retailer from more distant regional factories abandoned the process. The evaluation of the outcomes experienced by the two manufacturers allows us to examine contexts in fine-grained detail and explain why introducing information sharing in the S&OP processes produce — or fail to produce — benefits. The paper contributes to the supply chain information sharing literature by presenting a field tested and evolved S&OP design for non-standard demand situations, and by a contextual analysis of the mechanisms that produce the benefits of retailer collaboration and information sharing in the S&OP process.

- Whether free returns create economic value for online retailers is a question of increasing importance. Using order-level data from an online fashion retailer in Sweden, we investigate the introduction of free returns for customers in Denmark starting November 1, 2017, but not for customers in Sweden, Norway, Finland, France, Germany, and the rest of Europe (the control group). Using difference-in-differences, with and without sample matching, the introduction of free returns increased the order bill by 54.95 Swedish Krona (SEK) (9.15%), product variety per order by 0.057 (8.74%), gross margin per order by 29.90 SEK (9.71%), and returns by 0.195 items per order (7.86%). This likelihood of increased returns was generally similar across different product categories. The findings are robust to parallel trends, event studies, placebo effects, alternative control groups (with Scandinavian countries, Sweden and Norway), country-time trends, and correlations between outcome variables. Based on back-of-the-envelope calculations, the cost of offering free returns is greater than the increase in gross profit driven by free returns. Though our results show that free returns may not be of short-term benefit, retailers must also consider the long-term strategic implications of free returns.

Judgmental selection of forecasting models

- In this paper, we explored how judgment can be used to improve the selection of a forecasting model. We compared the performance of judgmental model selection against a standard algorithm based on information criteria. We also examined the efficacy of a judgmental model-build approach, in which experts were asked to decide on the existence of the structural components (trend and seasonality) of the time series instead of directly selecting a model from a choice set. Our behavioral study used data from almost 700 participants, including forecasting practitioners. The results from our experiment suggest that selecting models judgmentally results in performance that is on par, if not better, to that of algorithmic selection. Further, judgmental model selection helps to avoid the worst models more frequently compared to algorithmic selection. Finally, a simple combination of the statistical and judgmental selections and judgmental aggregation significantly outperform both statistical and judgmental selections.

- Objectives: To evaluate effects of electro–acupuncture (EA) on general psychological distress and relate to experience of climacteric symptoms in 30 postmenopausal women. Design: A randomised single-blind controlled design was used to evaluate effects of EA and extremely superficial needle insertion, with the latter serving as a near-placebo control. Settings: The Linköping University Hospital in Sweden. Interventions: Fourteen treatments during 12 weeks with follow-ups at 3 and 6 months. Outcome measures: General psychological well-being, mood and experience of climacteric symptoms. Results: Mood Scale improved only in EA group and not until 12 weeks compared to baseline, from 110 to 129 (P=0.01), and to 120 at 3-month follow-up (P=0.04). Mood was significantly better than control at 8 (P=0.05) and 12 weeks (P=0.01). Visual analogue scale estimation of climacteric symptoms was decreased at 4 weeks in both groups, and lasted throughout the study period, in EA group from 5 to 2 (P=0.04) and in control group from 5 to 3 (P=0.02) at 6-month follow-up. Well-being was ameliorated from 4 weeks in EA and from 8 weeks in control group until end of study (P=0.01, P=0.03). No significant differences on climacteric symptoms or well-being existed between the groups. Conclusions: This study does not show that EA is better than superficial needle insertion for the amelioration of general psychological distress and experience of climacteric symptoms in women with vasomotor symptoms after menopause. However, the more pronounced effect on mood suggests that EA might have additional effects compared with superficial needle insertion.

Hybrid digital manufacturing: Capturing the value of digitalization

- A chasm is growing between the advanced technologies available for improving manufacturing operations and those effectively used in practice. The vision of Industry 4.0 is to mobilize industry to seek out these possibilities for improvement and to close the gap between opportunity and reality. However, when compared with more established improvement opportunities such as lean manufacturing, the digitalization of manufacturing lacks in both paradigmatic examples and an understanding of how to achieve the benefits. This lack is a complication of concern: Without an appropriate operations strategy to capture the value of digitalization, manufacturing companies will be unable to focus on technological investments and operational changes. To address this concern, operations management academics must develop new theory through active engagement in the practice of digitalization in manufacturing. This research presents a paradigmatic example, based on engaged scholarship, focused on effectively combining novel object-interactive and conventional manufacturing syntax for benefiting from digitalization in internal operations and the wider supply chain. The contribution to literature is a novel operations strategy—hybrid digital manufacturing—for capturing the value of Industry 4.0 technologies.
