Jung, Y.,Pawlowski, S.D.,Kim, H.W. Butterworths ; Elsevier Science Ltd 2017 INTERNATIONAL JOURNAL OF INFORMATION MANAGEMENT - Vol.37 No.1

There is scant research on the broader outcomes of IT in users' life contexts beyond adoption. This study uses a goal hierarchy approach to deepen our understanding of the relationship between the use of Facebook and psychological well-being (PWB) in young adults. The study applies a mixed-method design that combines means-end analysis and regression analysis to examine data collected from laddering interviews with 161 Facebook users. The means-end chain analysis provided knowledge of the hierarchical goal structure in Facebook (i.e., activities→mediated goals→ultimate goals). Regression analysis was used to identify the relationships between the ultimate goals of Facebook use (e.g., psychological stability, belongingness) and the dimensions of PWB (e.g., self-acceptance, autonomy). The findings explain the significant association of Facebook use with well-being and the dual outcomes of enjoyment (positive in SNS; negative in users' lives). Prior research focused on relationships among abstract factors, but this study delivers a more specific and nuanced explanation of user behavior on SNSs by providing knowledge of how specific Facebook activities relate to goals and PWB.

Understanding consumption in social virtual worlds: A sensemaking perspective on the consumption of virtual goods

Jung, Y.,Pawlowski, S.D. College of Business Administration, University of 2014 Journal of Business Research Vol.67 No.10

Virtual consumption involves consuming virtual goods in cyberspace. Virtual consumption activities are evolving into an essential activity in social virtual worlds. Despite the growing importance of this activity, little research examines this phenomenon. The current study investigates the fundamental question of how users understand the consumption of virtual goods. Using the theory of social representations and core-periphery analysis, this study elicits and analyzes the social representation of virtual consumption. Study participants are 154 Second Life users. Results identify 32 concepts and relationships representing the collective perceptions of virtual consumption in this social virtual world. Social representation map interpretations point to several key themes that provide a foundation for future investigations of virtual economy consumption behavior.

Patel Madhav Rajesh,Jacob Kevin Chacko,Zamanian Cameron,Pawlowski Hanna,Prabhu Michael Clifford,Vanjani Nisheka Navin,Singh Kern 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.2

Study Design: Retrospective study.Purpose: To compare perioperative outcomes, patient-reported outcome measures (PROMs), and minimal clinically important difference (MCID) achievement rates for an obese patient cohort between single-level minimally invasive (MIS) transforaminal lumbar interbody fusion (TLIF) vs. anterior lumbar interbody fusion (ALIF).Overview of Literature: To the best of our knowledge, no study has compared the outcomes of MIS TLIF and ALIF in an obese population.Methods: Obese patients (body mass index [BMI] ≥30.0 kg/m2) who underwent single-level MIS TLIF or ALIF at L5/S1 were included in the study. Demographic/perioperative variables, presenting patient pathology, and 1-year arthrodesis statistics were collected. PROM scores for Visual Analog Scale (VAS) back/leg, Oswestry Disability Index, 12-item Short Form Physical Composite Scale, and Patient-Reported Outcome Measurement Information System Physical Function (PROMIS-PF) were collected from preoperative and postoperative (6 weeks, 12 weeks, 6 months, 1 year, 2 years) PROMIS-PF. The obese patients were classified based on the procedure they underwent (MIS TLIF vs. ALIF).Results: The criteria were met by 210 patients in total. After coarsened exact matching for Charlson comorbidity index score, degenerative spondylolisthesis, isthmic spondylolisthesis, degenerative scoliosis, foraminal stenosis, insurance, male, and ethnicity, 94 obese patients were included in the total cohort, with 59 receiving MIS TLIF and 35 receiving ALIF. ALIF recipients had higher PROMIS-PF scores at 6 weeks (p=0.014) and 12 weeks (p=0.030), as well as a higher VAS leg at 2 years (p=0.017). Following multiple regression accounting for differences in baseline BMI, only the 6-week PROMIS-PF significantly differed (p=0.028), with no other intergroup differences in mean PROMs between fusion types. Aside from a significantly higher 6-week MCID achievement rate for PROMIS-PF among ALIF recipients (p=0.006), no differences in attainment were observed.Conclusions: There were no statistically significant differences in perioperative characteristics, fusion rates, PROMs, or MCID achievement between obese patients receiving MIS TLIF vs. ALIF. As a result, our findings indicate that MIS TLIF and ALIF at L5/S1 are equally effective in an obese patient population.

Patel Madhav Rajesh,Jacob Kevin Chacko,Amin Kanhai S.,Ribot Max A.,Pawlowski Hanna,Prabhu Michael C.,Vanjani Nisheka Navin,Singh Kern 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.1

Study Design: This was a retrospective cohort study.Purpose: This study investigated the influence of preoperative mental health on patient-reported outcome measures (PROMs) and minimal clinically important difference (MCID) among workers’ compensation (WC) recipients undergoing minimally invasive transforaminal lumbar interbody fusion (MIS TLIF).Overview of Literature: No studies have evaluated the impact of preoperative mental functioning on outcomes following MIS TLIF among WC claimants.Methods: WC recipients undergoing single-level MIS TLIF were identified. PROMs of Visual Analog Scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), 12-item Short Form Physical and Mental Composite Scale (SF-12 PCS/MCS), and Patient-Reported Outcomes Measurement Information System Physical Function evaluated subjects preoperatively/postoperatively. Subjects were grouped according to preoperative SF-12 MCS: <41 vs. ≥41. Demographic/perioperative variables, PROMs, and MCID were compared using inferential statistics. Multiple regression was used to account for differences in spinal pathology.Results: The SF-12 MCS <41 and SF-12 MCS ≥41 groups included 48 and 45 patients, respectively. Significant differences in ΔPROMs were observed at SF-12 MCS at all timepoints, except at 6 months (p≤0.041, all). The SF-12 MCS <41 group had worse preoperative to 6-months SF-12 MCS, 12-weeks/6-months VAS back, 12-week VAS leg, and preoperative to 6-months ODI (p≤0.029, all). The SF-12 MCS <41 group had greater MCID achievement for overall ODI and 6-weeks/1-year/overall SF-12 MCS (p≤0.043, all); the SF-12 MCS ≥41 group had greater attainment for 6-month VAS back (p=0.004).Conclusions: Poorer mental functioning adversely affected the baseline and intermediate postoperative quality-of-life outcomes pertaining to mental health, back pain, and disability among WC recipients undergoing lumbar fusion. However, outcomes did not differ 1–2 years after surgery. While MCID achievement for pain and physical function was largely unaffected by preoperative mental health score, WC recipients with poorer baseline mental health demonstrated higher rates of overall clinically meaningful improvements for disability and mental health

History and Evolution of the Minimally Invasive Transforaminal Lumbar Interbody Fusion

Michael C. Prabhu,Kevin C. Jacob,Madhav R. Patel,Hanna Pawlowski,Nisheka N. Vanjani,Kern Singh 대한척추신경외과학회 2022 Neurospine Vol.19 No.3

The minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) is a popular surgical technique for lumbar arthrodesis, widely considered to hold great efficacy while conferring an impressive safety profile through the minimization of soft tissue damage. This elegant approach to lumbar stabilization is the byproduct of several innovations throughout the past century. In 1934, Mixter and Barr’s paper in the New England Journal of Medicine elucidated the role of disc herniation in spinal instability and radiculopathy, prompting surgeons to explore new approaches and instruments to access the disc space. In 1944, Briggs and Milligan published their novel technique, the posterior lumbar interbody fusion (PLIF), involving continuous removal of vertebral bone chips and replacement of the disc with a round bone peg. The following decades witnessed several PLIF modifications, including the addition of long pedicle screws. In 1982, Harms and Rolinger sought to redefine the posterior corridor by approaching the disc space through the intervertebral foramen, establishing the transforaminal lumbar interbody fusion (TLIF). In the 1990s, lumbar spine surgery experienced a paradigm shift, with surgeons placing increased emphasis on tissuesparing minimally invasive techniques. Spurred by this revolution, Foley and Lefkowitz published the novel MIS-TLIF technique in 2002. The MIS-TLIF has demonstrated comparable surgical outcomes to the TLIF, with an improved safety profile. Here, we present a view into the history of the posterior-approach treatment of the discogenic radiculopathy, culminating in the MIS-TLIF. Additionally, we evaluate the hallmark characteristics, technical variability, and reported outcomes of the modern MIS-TLIF and take a brief look at technologies that may define the future MIS-TLIF.

Does Baseline Severity of Arm Pain Influence Outcomes Following Single-Level Anterior Cervical Discectomy and Fusion?

Patel Madhav Rajesh,Jacob Kevin Chacko,Chavez Frank A.,Parsons Alexander W.,Vanjani Nisheka Navin,Pawlowski Hanna,Prabhu Michael Clifford,Singh Kern 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.3

Study Design: Retrospective cohort.Purpose: To assess preoperative arm pain severity influence on postoperative patient-reported outcomes measures (PROMs) and minimal clinically important difference (MCID) achievement following single-level anterior cervical discectomy and fusion (ACDF).Overview of Literature: There is evidence that preoperative symptom severity can affect postoperative outcomes. Few have evaluated this association between preoperative arm pain severity and postoperative PROMs and MCID achievement following ACDF.Methods: Individuals undergoing single-level ACDF were identified. Patients were grouped by preoperative Visual Analog Scale (VAS) arm ≤8 vs. >8. PROMs collected preoperatively and postoperatively included VAS-arm/VAS-neck/Neck Disability Index (NDI)/12-item Short Form (SF-12) Physical Composite Score (PCS)/SF-12 mental composite score (MCS)/Patient-Reported Outcomes Measurement Information System physical function (PROMIS-PF). Demographics, PROMs, and MCID rates were compared between cohorts.Results: A total of 128 patients were included. The VAS arm ≤8 cohort significantly improved for all PROMs excepting VAS arm at 1-year/2-years, SF-12 MCS at 12-weeks/1-year/2-years, and SF-12 PCS/PROMIS-PF at 6-weeks, only (<i>p</i> ≤0.021, all). The VAS arm >8 cohort significantly improved for VAS neck at all timepoints, VAS arm from 6-weeks to 1-year, NDI from 6-weeks to 6-months, and SF-12 MCS/PROMIS-PF at 6-months (<i>p</i> ≤0.038, all). Postoperatively, the VAS arm >8 cohort had higher VAS-neck (6 weeks/6 months), VAS-arm (12 weeks/6 months), NDI (6 weeks/6 months), lower SF-12 MCS (6 weeks/6 months), SF-12 PCS (6 months), and PROMISPF (12 weeks/6 months) (<i>p</i> ≤0.038, all). MCID achievement rates were higher among the VAS arm >8 cohort for the VAS-arm at 6-weeks/12-weeks/1-year/overall and NDI at 2 years (<i>p</i> ≤0.038, all).Conclusions: Significance in PROM score differences between VAS arm ≤8 vs. >8 generally dissipated at the 1-year and 2-year timepoint, although higher preoperative arm pain patients suffered from worse pain, disability, and mental/physical function scores. Furthermore, clinically meaningful rates of improvement were similar throughout the vast majority of timepoints for all PROMs studied.

Geoghegan Cara E.,Mohan Shruthi,Lynch Conor P.,Cha Elliot D. K.,Jacob Kevin C.,Patel Madhav R.,Prabhu Michael C.,Vanjani Nisheka N.,Pawlowski Hanna,Singh Kern 대한척추외과학회 2023 Asian Spine Journal Vol.17 No.1

Study Design: Retrospective cohort. Purpose: To evaluate the validity of established severity thresholds for Neck Disability Index (NDI) among patients undergoing anterior cervical discectomy and fusion (ACDF) or cervical disc arthroplasty (CDA). Overview of Literature: Few studies have examined the validity of established NDI threshold values among patients undergoing ACDF or CDA. Methods: A surgical database was reviewed to identify patients undergoing cervical spine procedures. Demographics, operative characteristics, comorbidities, NDI, Visual Analog Scale (VAS), and 12-item Short Form (SF-12) physical and mental composite scores (PCS and MCS) were recorded. NDI severity was categorized using previously established threshold values. Improvement from preoperative scores at each postoperative timepoint and convergent validity of NDI was evaluated. Discriminant validity of NDI was evaluated against VAS neck and arm and SF-12 PCS and MCS. Results: All 290 patients included in the study demonstrated significant improvements from baseline values for all patient-reported outcome measures (PROMs) at all postoperative timepoints (p<0.001) except SF-12 MCS at 2 years (p=0.393). NDI showed a moderate-to-strong correlation (r≥0.419) at most timepoints for VAS neck, VAS arm, SF-12 PCS, and SF-12 MCS (p<0.001, all). NDI severity categories demonstrated significant differences in mean VAS neck, VAS arm, SF-12 PCS, and SF-12 MCS at all timepoints (p<0.001, all). Differences between NDI severity groups were not uniform for all PROMs. VAS neck values demonstrated significant intergroup differences at most timepoints, whereas SF-12 MCS showed significantly different values between most severity groups. Conclusions: Neck disability is strongly correlated with neck and arm pain, physical function, and mental health and demonstrates worse outcomes with increasing severity. Previously established severity categories may be more applicable to pain than physical function or mental health and may be more uniformly applied preoperatively for cervical spine patients.
