How to turn a Cinderella product into a market queen

The case of Italian grappa shows that more than marketing is needed to raise a product's market status, write Giuseppe Delmestri and Royston Greenwoo

How Cinderella Became a Queen: Theorizing Radical Status Change

Using a case study of the Italian spirit grappa, we examine status recategorization - the vertical extension and reclassification of an entire market category. Grappa was historically a low-status product, but in the 1970s one regional distiller took steps that led to a radical break from its traditional image, so that in just over a decade high-quality grappa became an exemplar of cultured Italian lifestyle and held a market position in the same class as cognac and whisky. We use this context to articulate "theorization by allusion", which occurs through three mechanisms: category detachment-distancing a social object from its existing category; category emulation-presenting that object so that it hints at the practices of a high-status category; and category sublimation-shifting from local, field-specific references to broader, societal-level frames. This novel theorization is particularly appropriate for explaining change from low to high status because it avoids resistance to and contestation of such change (by customers, media, and other sources) as a result of status imperatives, which may be especially strong in mature fields. Unlike prior studies that have examined the status of organizations within a category, ours foregrounds shifts in the status and social meaning of a market category itself

Risk of adverse events following the initiation of antihypertensives in older people with complex health needs:a self-controlled case series in the United Kingdom

BACKGROUND: We assessed the risk of adverse events-severe acute kidney injury (AKI), falls and fractures-associated with use of antihypertensives in older patients with complex health needs (CHN). SETTING: UK primary care linked to inpatient and mortality records. METHODS: The source population comprised patients aged &gt;65, with ≥1 year of registration and unexposed to antihypertensives in the year before study start. We identified three cohorts of patients with CHN, namely, unplanned hospitalisations, frailty (electronic frailty index deficit count ≥3) and polypharmacy (prescription of ≥10 medicines). Patients in any of these cohorts were included in the CHN cohort. We conducted self-controlled case series for each cohort and outcome (AKI, falls, fractures). Incidence rate ratios (IRRs) were estimated by dividing event rates (i) during overall antihypertensive exposed patient-time over unexposed patient-time; and (ii) in the first 30 days after treatment initiation over unexposed patient-time. RESULTS:Among 42,483 patients in the CHN cohort, 7,240, 5,164 and 450 individuals had falls, fractures or AKI, respectively. We observed an increased risk for AKI associated with exposure to antihypertensives across all cohorts (CHN: IRR 2.36 [95% CI: 1.68-3.31]). In the 30 days post-antihypertensive treatment initiation, a 35-50% increased risk for falls was found across all cohorts and increased fracture risk in the frailty cohort (IRR 1.38 [1.03-1.84]). No increased risk for falls/fractures was associated with continuation of antihypertensive treatment or overall use. CONCLUSION: Treatment with antihypertensives in older patients was associated with increased risk of AKI and transiently elevated risk of falls in the 30 days after starting antihypertensive therapy.</p

Natural history of radiographic first metatarsophalangeal joint osteoarthritis: A nineteen‐year population‐based cohort study

Objective: To assess the long-term prevalence, natural history, progression and incidence of 73 radiographic first metatarsophalangeal joint (1st MTPJ) osteoarthritis (OA). Methods: A longitudinal, cohort design was used in which radiographic OA at the 1st MTPJ was 75 investigated in participants at year 6 (1995) and year 23 (2013-2015) from the Chingford 1000 76 Women study. Radiographic features of osteophytes (OPs) and/or joint space narrowing (JSN) at the 77 1st MTPJ were scored according to a validated foot atlas. Natural history was determined by the 78 change in prevalence, incidence, progression and worsening of OA in the 1st MTPJ. Results: Complete case matched foot radiographic data were available for 193 of the women 80 currently enrolled in the study, mean age: 75.7 years (SD: 5.2; range 69-90). At the level of the 1st 81 MTPJ, prevalence of OA at year 6 was 21.76% in the left and 24.35% in the right and at year 23 was 82 23.83% in the left and 32.64% in the right. Over the 19-year period, 13.5% of women developed 83 incident OA in the right 1st MTPJ and 8.3% in the left. Both progression and worsening of OA were 84 more evident for OPs and in the right 1st MTPJs. Conclusion: In this longest study of the natural history of radiographic 1st MTPJ OA to date, the 86 prevalence and incidence of 1st MTPJ OA increased over a 19-year period. Progression and/or 87 worsening of 1st MTPJ OA over time appears to be driven by OP development rather than JSN 88 suggestive of a biomechanical cause

Observational methods for COVID-19 vaccine effectiveness research:an empirical evaluation and target trial emulation

Background:There are scarce data on best practices to control for confounding in observational studies assessing vaccine effectiveness to prevent COVID-19. We compared the performance of three well-established methods [overlap weighting, inverse probability treatment weighting and propensity score (PS) matching] to minimize confounding when comparing vaccinated and unvaccinated people. Subsequently, we conducted a target trial emulation to study the ability of these methods to replicate COVID-19 vaccine trials.Methods:We included all individuals aged ≥75 from primary care records from the UK [Clinical Practice Research Datalink (CPRD) AURUM], who were not infected with or vaccinated against SARS-CoV-2 as of 4 January 2021. Vaccination status was then defined based on first COVID-19 vaccine dose exposure between 4 January 2021 and 28 January 2021. Lasso regression was used to calculate PS. Location, age, prior observation time, regional vaccination rates, testing effort and COVID-19 incidence rates at index date were forced into the PS. Following PS weighting and matching, the three methods were compared for remaining covariate imbalance and residual confounding. Last, a target trial emulation comparing COVID-19 at 3 and 12 weeks after first vaccine dose vs unvaccinated was conducted.Results:Vaccinated and unvaccinated cohorts comprised 583 813 and 332 315 individuals for weighting, respectively, and 459 000 individuals in the matched cohorts. Overlap weighting performed best in terms of minimizing confounding and systematic error. Overlap weighting successfully replicated estimates from clinical trials for vaccine effectiveness for ChAdOx1 (57%) and BNT162b2 (75%) at 12 weeks.Conclusion:Overlap weighting performed best in our setting. Our results based on overlap weighting replicate previous pivotal trials for the two first COVID-19 vaccines approved in Europe

Institutional legacies in TNCs and their management through training academies: the case of transnational law firms in Italy

This paper highlights the effects of heterogeneous institutional contexts on transnational professional service firms, a relatively understudied issue. Specifically the paper provides empirical analysis of how the specificities of the Italian institutional context affect the activities of English legal professional service firms in Milan. This reveals the intimate connection between varieties of capitalisms, place-specific workplace cultures and practices, and the institution-related challenges transnational professional service firms and all transnational corporations (TNCs) face. The paper also reveals the way institutionally generated differences at the level of work practices are managed in transnational law firms through worldwide training programmes designed to ‘govern’ the practices of workers in different parts of the TNC’s network. This highlights the importance of studying attempts to manage institutional heterogeneity at the level of workplace practices, something often missed in existing meso-scale studies of TNCs’ governance structures. Consequently, detailed empirical archaeologies exploring the direct links between institutions and practices are highlighted as being an important as part of future research analysing the effects of institutions on TNCs

Longitudinal trajectories of frailty are associated with short-term mortality in older people: a joint latent class models analysis using two UK primary care databases

Objective: Frailty is a dynamic health state that changes over time. Our hypothesis was that there are identifiable subgroups of the older population that have specific patterns of deterioration. The objective of this study was to evaluate the application of joint latent class model (JLCM) in identifying trajectories of frailty progression over time and their group-specific risk of death in older people. Study design and setting: The primary care records of UK patients, aged over 65 as of January 1st 2010, included in the CPRD: GOLD and AURUM databases, were analysed and linked to mortality data. Electronic frailty index (eFI) scores were calculated at baseline and annually in subsequent years (2010-2013). JLCM was used to divide the population into clusters with different trajectories and associated mortality hazard ratios (HR). The model was built in GOLD and validated in AURUM. Results: Five trajectory clusters were identified and characterised based on baseline and speed of progression: low-slow, low-moderate, low-rapid, high-slow and high-rapid. The high-rapid cluster had the highest average starting eFI score; 7.9, while low-rapid cluster had the steepest rate of eFI progression; 1.7. Taking the low-slow cluster as reference, low-rapid and high-rapid had the highest HRs: 3.73 (95%CI 3.71 to 3.76) and 3.63 (3.57 to 3.69), respectively. Good validation was found in the AURUM population. Conclusion: Our research found that there are vulnerable subgroups of the older population who are currently frail or have rapid frailty progression. Such groups may be targeted for greater healthcare monitoring

Primary care consultations and pain medicine prescriptions: a comparison between patients with and without chronic pain after total knee replacement

BACKGROUND: Approximately 20% of patients experience chronic pain after total knee replacement (TKR). The impact of chronic pain after TKR on primary care services in the UK is currently unknown. The aim of this study was to compare primary care consultations and pain medicine prescriptions between patients with and without chronic pain after TKR. METHODS: Data from 5,055 patients who received TKR between 2009 and 2016 with anonymised linked data from the Clinical Practice Research Datalink Gold (CPRD) and English Hospital Episode Statistics (HES) Patient Reported Outcome Measures (PROMs) programme were analysed. The exposure time was from 10 years pre-operative to eight years post-operative. Patients with a score ≤ 14 on the Oxford Knee Score pain component scale at 6 months post-operative were classified as having chronic pain after TKR. Primary care consultations and prescribed pain medicines were quantified, and costs calculated based on national cost data. RESULTS: 721 patients (14%) had chronic pain after TKR. The prevalence and costs of primary care consultations and pain medicine prescriptions per year were consistently higher for patients with chronic pain after TKR compared with those without chronic pain after TKR; these differences were observed both before and after surgery. There was a substantial and sustained increase in the cost of opioid prescriptions after surgery for patients with chronic pain after TKR, peaking at seven years post-operative. CONCLUSIONS: Increased primary care consultations and pain medicine prescriptions associated with chronic pain after TKR represent a considerable financial cost to primary care services. Evaluation of interventions to reduce the risk of developing this pain condition and improve the early management of pain after TKR are needed to improve outcomes for patients and reduce costs to healthcare services.
