Published: February 2023

The gig economy provides workers with the benefits of autonomy and flexibility but at the expense of work identity and coworker bonds. Among the many reasons why gig workers leave their platforms, one unexplored aspect is the lack of an organization identity. In this study, we develop a team formation and interteam contest field experiment at a ride-sharing platform. We assign drivers to teams either randomly or based on similarity in age, hometown location, or productivity. Having these teams compete for cash prizes, we find that (1) compared with those in the control condition, treated drivers work longer hours and earn 12% higher revenue during the contest; (2) the treatment effect persists two weeks postcontest, albeit with half of the effect size; and (3) drivers in hometown-similar teams are more likely to communicate with each other, whereas those in age-similar teams continue to work longer hours and earn higher revenue during the two weeks after the contest ends. Together, our results show that platform designers can leverage team identity and team contests to increase revenue and worker engagement in a gig economy.This paper was accepted by David Simchi-Levi, behavioral economics and decision analysis.Funding: Financial support from the platform through the Michigan Institute for Data Science is gratefully acknowledged.Supplemental Material: The e-companion are data are available at https://doi.org/10.1287/mnsc.2022.4624 .
AS ARTES DE SI: epistemologias alternativas em processos artístico aquilombados
Authors: Souza Amalia 
Published: February 2023

As Artes de si: epistemologias alternativas em processos artístico aquilombados procura investigar processos artísticos tendo comunidades de palenques, quilombos, cumbes e marrons como horizontes de criação, produção, e fruição de obras criativas. Este artigo surge como um esforço para contribuir para a estrutura teórica crítica afro-referenciada para a prática artística para além de um paradigma eurocêntrico. Obras performativas de artistas negros, referências primárias desta investigação, serão investigadas a partir de uma perspectiva quilombola, procurando abrir articulações entre poéticas, posições, trajectórias, territórios, e teorias que desobedeçam aos parâmetros críticos onto-epistemológicos (Silva, 2019) fortemente inclinados para o universo das representações raciais. Assim, usamos a expressão Las Artes de si, tal como cunhada por Denetem (2019), para nos referirmos a estas performances, criações, e culturas materiais negras que operam a inadequação ontológica presente nas comunidades quilombolas, palenques, cumbes, e maroons, entendendo-as como referências das culturas afro-americanas.

Introduction
Chronic pain represents a major health issue, affecting the physical and mental health of approximately one in five people worldwide. It is now widely recognized that health professionals should use interventions that meet the needs of people living with chronic pain. Therefore, physiotherapists should attend to patients’ perceived needs regarding physiotherapy services, i.e. the needs that are perceived by patients themselves based on their beliefs, values, preferences and expectations. However, previous reviews have mainly focused on health professionals’ and experts’ evaluations of patients’ needs, which may result in inadequate answers to these needs. Therefore, a better understanding of patients’ perceived needs could lead to more ethical and higher quality physiotherapy services.

Objective
The aim of this scoping review is thus to explore what is known from the existing literature about the perceived needs of people living with chronic pain regarding physiotherapy services.

Methods
This scoping review will follow Arksey and O’Malley’s six-step framework. Medline, Embase, CINHAL, and APA PsycINFO will be used to search the scientific literature. The grey literature will also be searched using Google Scholar, OpenGrey and ProQuest Dissertation & Theses Global (PQDTGlobal). Studies published in English and French will only be considered. Two independent reviewers will perform the selection and extraction processes. Descriptive statistics will be performed to characterize the included studies. Quantitative, qualitative and mixed methods studies will be analyzed and synthetized using convergent qualitative meta-integration. Thereby, we will use the seven steps for convergent qualitative meta-integration proposed by Frantzen and Fetters to transform, analyze and integrate the quantitative and qualitative data.

Inclusion criteria
Included studies will describe the perceived needs of adults living with chronic pain regarding physiotherapy services. Studies focusing on the perspectives of health professionals and rehabilitation services other than physiotherapy will be excluded.

Published: February 2023

Objectives
A phase II = design is used to evaluate the efficacy and feasibility of full dose docetaxel, platinum, and 5-fluorouracil (TPF) in a sequential chemoradiation treatment locally advanced (LA) or oligometastatic (OM) NPC patients.

Materials and methods
Twenty patients with LANPC (M0 cohort) and six patients with OMNPC (M1 cohort) received induction standard dose T (75 mg/m2) P (75 mg/m2) F (750 mg/m2 IVCI x 5days) x 3 followed by weekly cisplatin (40 mg/m2) or carboplatin (AUC 1.5) x 6 concurrent with radiation therapy of 70 Gy over 6.5–7 weeks. The first five patients received bevacizumab as part of an exploratory objective of hypoxia modification using correlative fluoromisonidasole (18F-MISO) PET CT scanning.

Results
The 18F-MISO imaging failed to reveal adequate levels of baseline hypoxia necessary to evaluate for changes with chemotherapy and bevacizumab. Ninety percent of M0 patients and 83% of M1 patients received the full-intended TPF and radiation dose. Eighty-five percent of M0 patients and all M1 patients received at least 60% of the full-intended concurrent platinum dose. The 2-year progression free survival (PFS) rate for the M0 cohort was 90% (95% CI: 77.8%– 100%), and was sustained at 5 years. The 2-year PFS rate for the M1 cohort was 66.7% (95% CI: 37.9%– 100%). The 2-year overall survival (OS) rates for the M0 and M1 cohorts were 100% and 83.3% (95% CI: 58.3%– 100%), respectively. At five years, OS was 94.4% for the M0 cohort.

Conclusion
Administration of standard-dose TPF as induction chemotherapy in this NPC patient population is both feasible and effective when coupled with definitive concurrent chemoradiation.

Published: February 2023

ObjectiveThe purpose of this study was to examine the sex lives of male cirrhotic patients organic factors affect them.MethodWe did an observational study of 220 cirrhotic men’s satisfaction with their sexual lives. Assessment of sex satisfaction was carried out using the New Sexual Satisfaction Scale. The frequency of intercourse and masturbation was estimated. Then, the levels of albumin, total bilirubin, vitamin D, and sex steroids were examined. Ascites and sarcopenia subgroups of our patients were stratified.ResultsAlong with sex steroids, albumin, total bilirubin, and vitamin D all had an impact on how satisfying sex was (r = 0.22), (r = 0.24), and (r = −0.17) affected sex satisfaction. There were strong positive correlations between vitamin D (r = 0.33), albumin (r = 0.59), and free testosterone, along with a negative correlation between total bilirubin (r = −0.63) and free testosterone. An imbalance in sex steroid levels was observed, leading to decreased frequency of intercourse(p < 0.0001), weakened erections(p < 0.0001), and reduced quality of orgasm (p < 0.0001). Significant new sex behavior changes were found, such as an increase in masturbation. Physical limitations such as ascites and sarcopenia also impacted the decreasing sex life.ConclusionThe sex life of cirrhotic men is affected. The decrease in the frequency of intercourse and sexual satisfaction is noticeable in male patients and leads to increased masturbation. Free Testosterone, vitamin D, albumin, and bilirubin play role in their sex life. In addition, ascites and sarcopenia not only affect their sex life but also hamper the quality of their well-being.
Barriers to conducting independent quantitative research in low-income countries: A cross-sectional study of public health graduate students in Liberia

Published: February 2023

Introduction
During recent disease outbreaks, quantitative research has been used to investigate intervention scenarios while accounting for local epidemiological, social, and clinical context. Despite the value of such work, few documented research efforts have been observed to originate from low-income countries. This study aimed to assess barriers that may be limiting the awareness and conduct of quantitative research among Liberian public health graduate students.

Methods
A semi-structured questionnaire was administered September-November 2021 to Master’s in Public Health (MPH) students in Liberia. Potential barriers around technology access, understanding of quantitative science, and availability of mentorship were interrogated. Associations between barriers and self-reported likelihood of conducting quantitative research within six months of the investigation period were evaluated using ordinal logistic regression.

Results
Among 120 participating MPH students, 86% reported owning a personal computer, but 18.4% and 39.4% had machines with malfunctioning hardware and/or with battery power lasting ≤2 hours, respectively. On average, students reported having poor internet network 3.4 days weekly. 47% reported never using any computer software for analysis, and 46% reported no specific knowledge on statistical analysis. Students indicated spending a median 30 minutes per week reading scientific articles. Moreover, 50% had no access to quantitative research mentors. Despite barriers, 59% indicated they were very likely to undertake quantitative research in the next 6 months; only 7% indicated they were not at all likely. Computer ownership was found to be statistically significantly associated with higher likelihood of conducting quantitative research in the multivariable analysis (aOR: 4.90,95% CI: 1.54–16.3).

Conclusion
The high likelihood of conducting quantitative research among MPH students contrasts with limitations around computing capacity, awareness of research tools/methods, and access to mentorship. To promote rigorous analytical research in Liberia, there is a need for systematic measures to enhance capacity for diverse quantitative methods through efforts sensitive to the local research environment.

Published: February 2023

Objective
A few earlier studies have found impaired endothelial function in patients with Myalgic Encephalomyelitis/Chronic Fatigue Syndrome (ME/CFS). The present study investigated large-vessel and small-vessel endothelial function in patients with ME/CFS.

Study design
The study was a substudy of the RituxME trial, a national, multicenter, randomized, double-blind, placebo-controlled phase III study on the effect of rituximab vs. placebo in ME/CFS patients in Norway. Flow-mediated dilation (FMD) and post-occlusive reactive hyperemia (PORH) was measured at baseline and after 18 months of treatment in 39 patients and compared with healthy controls. Other outcome measures were symptom severity and various physical function measures.

Results
ME/CFS patients had markedly reduced FMD compared to healthy controls at baseline (5.1% vs. 8.2%, p< 0.0001, adjusted for arterial diameter and sex), and significantly lower microvascular regulation measured by PORH than healthy controls (1354 PU vs. 2208 PU, p = 0.002). There were no differences between the treatment and placebo groups in symptom changes or vascular measures. As a group, the ME/CSF patients experienced a slight, but significant improvement in clinical symptoms after 18 months. PORH, but not FMD, was similarly improved (1360 to 1834 PU, p = 0.028). There was no significant correlation between FMD and PORH. There were non-significant tendencies towards associations between symptom severity/physical function measures and lower FMD and PORH, and a significant correlation between PORH and steps per 24 hours at baseline.

Conclusions
ME/CFS patients had reduced macro- and microvascular endothelial function, indicating that vascular homeostasis may play a role in the clinical presentation of this disease.

Background
Atrial fibrillation (AF) is associated with a five-fold increased risk of stroke and a two-fold increased risk of death. We aimed to quantify changes in new diagnoses of AF following the onset of the COVID-19 pandemic. Investigating changes in new diagnoses of AF is of relevance because delayed diagnosis interferes with timely treatment to prevent stroke, heart failure, and death.

Methods
Using De-identified Optum’s Clinformatics® Data Mart, we identified 19,500,401 beneficiaries continuously enrolled for 12 months in 2016-Q3 2020 with no history of AF. The primary outcome was new AF diagnoses per 30-day interval. Secondary outcomes included AF diagnosis in the inpatient setting, AF diagnosis in the outpatient setting, and ischemic stroke as initial manifestation of AF. We constructed seasonal autoregressive integrated moving average models to quantify changes in new AF diagnoses after the onset of the COVID-19 pandemic (3/11/2020, date of pandemic declaration). We tested whether changes in the new AF diagnoses differed by race and ethnicity.

Results
The average age of study participants was 51.0±18.5 years, and 52% of the sample was female. During the study period, 2.7% of the study sample had newly-diagnosed AF. New AF diagnoses decreased by 35% (95% CI, 21%-48%) after the onset of the COVID-19 pandemic, from 1.14 per 1000 individuals (95% CI, 1.05–1.24) to 0.74 per 1000 (95% CI, 0.64 to 0.83, p-value<0.001). New AF diagnoses decreased by 37% (95% CI, 13%- 55%) in the outpatient setting and by 29% (95% CI, 14%-43%) in the inpatient setting. The decrease in new AF diagnoses was similar across racial and ethnic subgroups.

Conclusion
In a nationwide cohort of 19.5 million individuals, new diagnoses of AF decreased substantially following the onset of the COVID-19 pandemic. Our findings evidence pandemic disruptions in access to care for AF, which are concerning because delayed diagnosis interferes with timely treatment to prevent complications.

BackgroundParkinson’s disease (PD) is a progressive, neurodegenerative disease with motor symptoms that are well understood, but non-motor symptoms may be present and appear at different temporal stages of the disease. Physical activity based on dance movements is emerging as a complementary therapeutic approach to a range of PD symptoms as a multidimensional activity that requires rhythmic synchronization and more neuromuscular functions.ObjectiveTo evaluate the effects of physical activity based on dance movements on the movement, executive functions, depressive symptoms, quality of life, and severity of PD in individuals diagnosed with PD.Methods13 individuals with PD (Hoehn & Yahr I-III, MDS-UPDRS 67.62 ± 20.83), underwent physical activity based on dance movements (2x week for 6 months). Participants were assessed at baseline and after 6 months on movement (POMA, TUG and MDS-UPDRS Part III), executive function (FAB), depressive symptoms (MADRS), quality of life (PDQ-39), and severity of PD (MDS-UPDRS TOTAL). Student’s t-test was used to compare pre and post-intervention results.ResultsWe observed a significant improvement in the movement (balance and gait) by the POMA test,p= 0.0207, executive function by the FAB test,p= 0.0074, abstract reasoning and inhibitory control by the FAB, Conceptualization test,p= 0.0062, and Inhibitory Control,p= 0.0064, depressive symptoms assessed by the MADRS test significantly reduced,p= 0.0214, and the quality of life by the PDQ-39 had a significant increase after the intervention,p= 0.0006, showed significant improvements between the pre-and post-intervention periods of physical activity based on dance movements.ConclusionPhysical activity based on dance movements contributed to significant improvements in movement (balance and gait), executive functions, especially in cognitive flexibility and inhibitory control, and the quality of life too. Sensorimotor integration, most cognitive processing and social skills may have contributed to the results.Trial registrationThe study was registered in the Brazilian registry of clinical trials:RBR-3bhbrb5.
Creatine kinase is associated with glycated haemoglobin in a nondiabetic population. The Tromsø study
Authors: Bekkelund Svein Ivar 
Published: February 2023

Background
Creatine kinase (CK) has been associated with insulin resistance and identified as a risk marker of cardiovascular disease largely by its relationship with hypertension and increased body mass index. This study determined whether CK is a predictor of glycated haemoglobin (HbA1C) in a nondiabetic general population.

Methods
Associations between CK and the outcome variable HbA1C (%) were performed by variance and multivariate analyses in 11662 nondiabetic subjects defined as HbA1C (%) <6.5 who participated in the population based Tromsø study (Tromsø 6) in Norway.

Results
Abnormal elevated CK was detected in 543/11662 participants (4.66%). Mean HbA1C (%) in the “high CK” group was 5.62 (SD = 0.33) compared to 5.52 (SD = 0.36) in the “normal CK” group, P <0.001. CK increased significantly and linearly with higher levels of HbA1C (%) quartiles in women (P <0.001) and non-linearly in men (P <0.001). In a multivariate analysis, CK was independently associated with HbA1C (%) after adjusting for age, sex, body mass index, blood pressure, glucose, lipids, C-reactive protein, creatinine, alanine transaminase and aspartate aminotransferase. A 1-unit increase in log CK was associated with a 0.17-unit increase in HbA1C (%).

Conclusion
These data demonstrate a positive and independent association between CK and glycated haemoglobin in a nondiabetic general population.
Preoperative upper tract invasive diagnostic modalities are associated with intravesical recurrence following surgery for upper tract urothelial carcinoma: A population-based study

Published: February 2023

Background
Intravesical recurrence (IVR) after surgery for upper tract urothelial carcinoma (UTUC) is a clinical problem. We investigated if preoperative invasive diagnostic modalities (IDM) such as antegrade/retrograde uretero-pyelography and/or selective urine cytology/barbotage, and URS with or without concomitant biopsy are associated with IVR after radical surgery for UTUC. Risk of death from urothelial cancer and all causes was investigated as secondary outcomes.

Methods
We investigated a population-based cohort of 1038 consecutive patients subjected to radical surgery for UTUC 2015–2019 in Sweden, using the Bladder Cancer Data Base Sweden (BladderBaSe 2.0), comprising all patients in the Swedish National Registry of Urinary Bladder Cancer. Risk estimates of IVR, death from urothelial cancer, and all causes was assessed using multivariable Cox regression models.

Results
The study included 536 cases with and 502 without preoperative IDM. IDM was associated with increased risk of IVR (HR 1.24, 95% CI 1.03–1.52) and risk of urothelial cancer death (HR 1.56, CI 1.12–2.18), compared to no IDM after a median follow-up of 1.3 yrs. Stratified analysis for tumor location showed that IDM was associated with risk of IVR in ureteric cancer (HR 1.66, 95% CI 1.21–2.28) but not in renal pelvic cancer (HR 1.07, 95% CI 0.81–1.41). Limitations included the observational setting and the lack of variables such as tumour grade, multifocality and preoperative hydronephrosis.

Conclusions
Worse outcomes for patients subjected to preoperative IDM highlight the need for carefully considering diagnostic decisions for UTUC patients, specifically in tumours located in the ureter.
