Authors: Liu Yin , Tan Huayi , Huang Can , Li Lifeng , Wu Sijie 
Published: January 2021

Background Polyphenols in extra virgin olive oil (EVOO) have been found to reduce the expression of PPARγ2, inhibit adipocyte differentiation, and enhance the formation of osteoblasts from bone marrow stem cells. However, the underlying mechanisms of their action remain unknown. Purpose To determine the sequential effects of EVOO on marrow fat expansion induced by estrogen deprivation using 3.0-T proton magnetic resonance (MR) spectroscopy in an ovariectomy (OVX) rabbit model of postmenopausal bone loss over a six-month period. Material and Methods A total of 45 female New Zealand rabbits were equally divided into sham-operation, OVX controls, and OVX treated with EVOO for six months. Marrow fat fraction was measured by MR spectroscopy at baseline conditions, and three and six months postoperatively, respectively. Serum bone biomarkers, lumbar and femoral bone mineral density, microtomographic parameters, biomechanical properties, and quantitative parameters of marrow adipocytes were studied. Results OVX was associated with marrow adiposity in a time-dependent manner, accompanied with increased bone turnover and impaired bone mass and trabecular microarchitecture. In OVX rabbits, EVOO markedly alleviated trabecular bone loss and reduced the accumulation of lipid droplets including adipocyte size, density, and areas of fat deposits in the bone marrow. EVOO prevented such changes in terms of both marrow adiposity and bone remodeling. Conclusion Early EVOO treatment may exert beneficial effects on bone by modulating marrow adiposity, which would support their protective effect against bone pathologies.

Background While the majority of bleeding complications after a percutaneous kidney biopsy (PKB) occur early (≤24 h), delayed onset bleeding complications (>24 h) have been rarely reported and can be catastrophic for the patient. Purpose To describe the incidence, risk factors, and outcomes of delayed bleeding complications after PKB. Material and Methods We retrospectively studied native and graft kidney biopsies in patients who developed delayed bleeding complications (>24 h) after the biopsy performed in the Department of Nephrology and Renal Transplantation of a tertiary care medical institution in north India between January 2014 to December 2018. Results Of the 4912 renal biopsies reviewed, 20 patients (16 men, 4 women; 0.40%) had a delayed biopsy bleeding complication. Of these patients, 95% had major bleeding complications requiring blood transfusions and 85% needed intervention like gelfoam/coil embolization. Despite intervention, one patient (5%) had mortality due to complications of bleeding and sepsis. When compared to a control group of patients with early biopsy bleed, patients with the delayed biopsy bleed had similar demographic and clinical profiles except for higher pre-biopsy hemoglobin and lower systolic and diastolic blood pressure. Conclusion A post-PKB delayed onset bleed is not uncommon, and the vast majority of these patients had major bleeding complications requiring blood transfusions and/or intervention like embolization. They had a similar demographic and clinical profile presentation as early bleed patients. Meticulous outpatient monitoring and patient education after discharge may be useful to detect this complication promptly and to intervene early to have good patient outcome.

Objective This study aims to investigate the change in quality adjusted life-years (QALYs) after providing oncology pharmacist services to assess its impact on humanistic outcome. Methods It was a prospective, single-centered study conducted for a period of two years at Bharat cancer Hospital and Nirali memorial radiation center, Surat. Patients were recruited into the control group (CG) and the intervention group (IG). The oncology pharmacist services (OPS) were provided only to the IG. The humanistic outcome was measured by incorporating the EQ-5D-5L instrument to calculate quality-adjusted life-years (QALYs) in both the groups. Patients have been provided with the EQ-5D-5L questionnaire at the pre-determined intervals i.e. before the commencement of chemotherapy and then after every chemotherapy cycle till the completion of treatment. The analysis was carried out using descriptive analysis (frequency distribution for categorical variables and measures of central tendency (median and average) and dispersion (std. deviation) for quantitative variables). Results A total of 230 patients were screened and from them 105 patients were recruited, out of which 54 patients were in CG and 51 patients in IG. AC regimen followed by weekly paclitaxel was prescribed in majority of the patients (CG: 59.3%; IG: 60.8%) followed by AC-TRA and AC regimen alone. The majority of patients in the CG were facing improper administration of pre-medication (83.3%), lack of knowledge regarding chemo-mixing, counselling in nursing staff (66.7%) and a sub-therapeutic dose of anti-emetics (37%). The baseline QALY at the inception of chemotherapy was 0.040 and 0.014 in CG and IG, respectively. After the completion of the 6 chemotherapy cycle, the QALY was found to be 0.042 and 0.043 in CG and IG, respectively. Conclusion The study has demonstrated that the improvisation in QALY after provision of oncology pharmacist services reflect the positive impact of oncology pharmacist on humanistic outcomes. The study also provided the opportunity to identify the thrust area where more clinical pharmacy exposure is needed in order to improve patient care.

Authors: Manouchehrinia Ali , Kingwell Elaine , Zhu Feng , Tremlett Helen , Hillert Jan , Ramanujam Ryan 
Published: January 2021

Background: Existing severity measurements in multiple sclerosis (MS) are often cross-sectional, making longitudinal comparisons of disease course between individuals difficult. Objective: The objective of this study is to create a severity metric that can reliably summarize a patient’s disease course. Methods: We developed the nARMSS – normalized ARMSS (age-related MS severity score) over follow-up, using the deviation of individual ARMSS scores from the expected value and integrated over the corresponding time period. The nARMSS scales from −5 to +5; a positive value indicates a more severe disease course for a patient when compared to other patients with similar disease timings. Results: Using Swedish MS registry data, the nARMSS was tested using data at 2 and 4 years of follow-up to predict the most severe quartile during the subsequent period up to 10 years total follow-up. The metric used was area under the curve of the receiver operating characteristic (AUC-ROC). This resulted in measurements of 0.929 and 0.941. In an external Canadian validation cohort, the equivalent AUC-ROCs were 0.901 and 0.908. Conclusion: The nARMSS provides a reliable, generalizable and easily measurable metric which makes longitudinal comparison of disease course between individuals feasible.

Published: January 2021

Introduction Assessing costs of an evidence-based health promotion programme is crucial to understand the economic feasibility of adopting or sustaining the programme. This study conducted a cost analysis of a remote patient monitoring (RPM) programme to enhance the post-discharge management of type 2 diabetes. Methods Using retrospective data collected during RPM implementation from September 2014 to February 2018, we estimated the costs of implementing an RPM in the primary care setting. Measures included total and average annual costs, costs per participant who was enrolled or completed the programme, and costs per person-day. We further conducted sensitivity and scenario analyses to examine variations in estimated programme costs associated with varying programme efficiencies and alternative personnel compositions of the RPM team. Results The total RPM implementation costs were estimated at US$4,374,544 with an average annual programme costs of US$1,249,870, which translated to US$3207 per participant ( n = 1364) completing the three-month programme. The per person-day cost was averaged at US$24 (182,932 person-days). Sensitivity and scenario analyses results indicate that the sustainment costs were approximately US$1.6 million annually and the per-person-day costs were between US$21 and US$29 with each nurse coach on average serving a panel of 62–93 patients. Conclusion The implementation and sustainment costs of an RPM programme, estimated under various assumptions of programme efficiency and care team compositions, as exemplified in this study, will help healthcare organizations make informed decisions in budgeting for and sustaining telehealth programmes to enhance diabetes management.

Published: January 2021

Background High-resolution ultrasound (HRU) has demonstrated utility in the diagnosis and treatment of carpal tunnel syndrome (CTS) by measuring the cross-sectional area (CSA) of the median nerve. We investigated whether HRU could be helpful in evaluating outcomes of carpal tunnel release in patients with severe CTS. Methods Patients greater than 18 years of age with severe CTS on electrodiagnostic (EDX) studies and scheduled to have carpal tunnel release were enrolled. At baseline visit within 6 weeks preoperatively, HRU was used to measure median nerve CSA at the carpal tunnel inlet and forearm, and the wrist/forearm ratio (WFR) was calculated. Patients also completed the Boston Carpal Tunnel Questionnaire (BCTQ). Ultrasound and BCTQ were repeated at 6 weeks and 6 months postoperatively. Results Twelve patients completed the study (average age, 69 years; range, 52-80 years). The WFR improved significantly at 6 weeks and reached normal levels at 6 months. The CSA at the wrist also improved at 6 months, although this did not reach statistical significance ( P = .059). Boston Carpal Tunnel Questionnaire symptoms and function scores improved significantly at 6 weeks and 6 months. Conclusions High-resolution ultrasound provides an objective assessment of surgical outcomes in cases of severe CTS, demonstrating normalization of WFR in our series of successful cases. Future study of poor outcomes may help determine whether improvement in WFR and CSA can provide reassurance and support for observation rather than reoperation. Ultrasound also provides anatomical evaluation and may be helpful in cases with medicolegal or psychosocial issues while potentially being less costly and better tolerated than EDX or magnetic resonance imaging.

Published: January 2021

Background Management of scaphoid fractures often requires advanced imaging to achieve accurate diagnoses and appropriate treatment. Digital tomosynthesis (DTS) is a cross-sectional imaging modality that may be used to substitute magnetic resonance imaging or computed tomographic scans. The purpose of this study is to: (1) determine the diagnostic accuracy of DTS in occult scaphoid fractures; and (2) report on the reduction of other advanced imaging when using DTS. Methods From May 2014 to October 2017, the charts of all patients who underwent scaphoid tomogram were retrospectively reviewed. The diagnostic accuracy of DTS for occult fracture was compared with 2-week follow-up plain films. To measure the reduction in utilization of advanced imaging, it was determined whether DTS eliminated the need for advanced imaging by providing adequate information regarding the clinical question. Results A total of 78 patients underwent scaphoid tomography in this time frame: 39 for occult fracture, 33 for fracture union, 5 for fracture morphology, and 1 for hardware positioning. For the detection of occult fracture, DTS had a sensitivity of 100%, specificity of 83%, positive predictive value of 64%, and negative predictive value of 100%. Advanced imaging was not used in 35 of the remaining 39 patients based on the results obtained by DTS. In patients who did receive advanced imaging, 83% of tomograms provided conclusive diagnostic information. Conclusions Digital tomosynthesis increases the diagnostic sensitivity of occult scaphoid fractures, reducing unnecessary immobilization and advanced imaging. Digital tomosynthesis provides clinical detail beyond plain film, which reduces the need to obtain advanced imaging when assessing union, fracture pattern, and hardware placement.

Objective The aim was to evaluate the utility of frailty, as defined by the modified Frailty Index-1 1 (mFI-11) on predicting outcomes following endovascular revascularisation in Asian patients with chronic limb-threatening ischaemia (CLTI). Methods CLTI patients who underwent endovascular revascularisation between January 2015 and March 2017 were included. Patients were retrospectively scored using the mFI-11 to categorise frailty as low, medium or high risk. Observed outcomes included 30-day complication rate and unplanned readmissions, 1-, 6- and 12-month mortality, and ambulation status at 6- and 12 months post-intervention. Results A total of 233 patients (250 procedures) were included; 137 (58.8%) were males and the mean age was 69.0 (±10.7) years. 202/233 (86.7%) were diabetic and 196/233 (84.1%) had a prior diagnosis of peripheral arterial disease (PAD). The mean mFI-11 score was 4.2 (±1.5). 28/233 (12.0%), 155/233 (66.5%), and 50/233 (21.5%) patients were deemed low (mF-11 score 0–2), moderate (mFI-11 score 3–5) and high (mFI-11 score 5–7) frailty risk, respectively. High frailty was associated with an increased 12-month mortality (OR 8.54, 95% CI 1.05–69.5; p = 0.05), 30-day complication rate (OR 9.41, 95% CI 2.01–44.1; p < 0.01) and 30-day unplanned readmission (OR 5.06, 95% CI 1.06–24.2; p = 0.04). Furthermore, a high score was associated with a significantly worse 6- (OR 0.320, 95% CI 0.120–0.840; p = 0.02) and 12-month (OR 0.270, 95% CI 0.100–0.710; p < 0.01) ambulatory status. Conclusion The mFI-11 is a useful, non-invasive tool that can be readily calculated using readily available patient data, for prediction of medium-term outcomes for Asian CLTI patients following endovascular revascularisation. Early recognition of short- and mid-term loss of ambulation status amongst high-frailty patients in this challenging cohort of patients could aid decision-making for whether a revascularisation or amputation-first policy is appropriate, and manage patient and caregiver expectations on potential improvement in functional outcome.

Authors: MacLean Simon B. M. , Bain Gregory I. 
Published: January 2021

We studied the kinematics of 20 wrists affected by Kienböck’s disease using four-dimensional computed tomography (4-D-CT) scanning. Degenerative changes progressed from the lunate facet to the scaphoid fossa at the radiocarpal articulation, then involved the midcarpal joint. Lunate fracture types included coronal (14/20), sagittal (10/20) and ligament attachment-types (8/20). Findings specific to dynamic scanning included the nutcracker phenomenon (12/20), anterior radiolunate impingement (7/20), internal instability of the lunate (6/20), ulnar styloid triquetral impingement (3/20) and dynamic proximal row instability (2/20). Ulnocarpal translocation was found in 4/20 cases. Dynamic 4-D-CT has helped us to identify a subset of pathology in Kienböck’s disease on assessment of static imaging. Better understanding of these phenomena can improve our understanding of symptoms and may help direct surgical treatment. Level of evidence: IV

Published: January 2021

Background Sex hormones are known to have some influence on nasal functions, but their effect on the decongestive response of the nasal mucosa during menstrual cycle is still undetermined. Objectives The aim of this study was to examine the nasal physiology, the interconnectedness of olfactory and respiratory nasal function and the decongestive response of the nasal mucosa during menstrual cycle. Methods This study included 101 healthy women aged 23.26 ± 4.81 years with a regular menstrual cycle. The nasal respiratory function and the decongestive response of the nasal mucosa were examined by rhinomanometry. Subjective sense of nasal obstruction and the subjective odor intensity were assessed by standardized questionnaires. The odor identification ability was assessed by Sniffin’ Sticks test. Results Statistically significant higher values of nasal resistance (0.311 ± 0.107 Pa/cm3/s) and NOSE score (11.893 ± 13.83) were observed in the ovulatory phase compared to the luteal (0.281 ± 0.084 Pa/cm3/s and 9.029 ± 11.12). An odor identification test score was significantly higher in luteal phase (12.476 ± 1.48) compared to the ovulatory phase (11.971 ± 1.51), opposite of odor intensity. The difference of nasal resistance before and after decongestion was significantly higher in ovulatory phase (0.105 ± 0.097 Pa/cm3/s) compared to the luteal (0.084 ± 0.079 Pa/cm3/s). Correlation between subjective and objective parameters of the examinated nasal functions was not statistically significant in any menstrual phase. Conclusion In the population of women studied, total nasal resistance and NOSE score were significantly lower in the luteal phase of the menstrual cycle. Odor identification was significantly higher in the luteal phase but odor intensity significantly higher in the ovulatory phase. The decongestive response of nasal mucosa was better in the ovulatory phase of the menstrual cycle.

Study Design: Scoping review. Objectives: To identify a practical and reproducible approach to organize Quality of Care Indicators (QoCI) in individuals with traumatic spinal cord injury (TSCI). Methods: A comprehensive literature review was conducted in the Cochrane Central Register of Controlled Trials (CENTRAL) (Date: May 2018), MEDLINE (1946 to May 2018), and EMBASE (1974 to May 2018). Two independent reviewers screened 6092 records and included 262 full texts, among which 60 studies were included for qualitative analysis. We included studies, with no language restriction, containing at least 1 quality of care indicator for individuals with traumatic spinal cord injury. Each potential indicator was evaluated in an online, focused group discussion to define its categorization (healthcare system structure, medical process, and individuals with Traumatic Spinal Cord Injury related outcomes), definition, survey options, and scale. Results: A total of 87 indicators were identified from 60 studies screened using our eligibility criteria. We defined each indicator. Out of 87 indicators, 37 appraised the healthcare system structure, 30 evaluated medical processes, and 20 included individuals with TSCI related outcomes. The healthcare system structure included the impact of the cost of hospitalization and rehabilitation, as well as staff and patient perception of treatment. The medical processes included targeting physical activities for improvement of health-related outcomes and complications. Changes in motor score, functional independence, and readmission rates were reported as individuals with TSCI-related outcomes indicators. Conclusion: Indicators of quality of care in the management of individuals with TSCI are important for health policy strategists to standardize healthcare assessment, for clinicians to improve care, and for data collection efforts including registries.

Published: January 2021

Background: The literature on upper extremity injuries in professional soccer players is scarce, and further insight into the onset and cause of these injuries as well as potential differences between goalkeepers and outfield players is important. Purpose: To investigate the epidemiology of hand, wrist, and forearm injuries in male professional soccer players between 2001 and 2019. Study Design: Descriptive epidemiology study. Methods: Between the 2001-2002 and 2018-2019 seasons, 120 European male soccer teams were followed prospectively for a varying number of seasons (558 team-seasons in total). Time-loss injuries and player-exposures to training sessions and matches were recorded on an individual basis in 6754 unique players. Injury incidence was reported as the number of injuries per 1000 player-hours, and between-group differences were analyzed using Z statistics and rate ratios (RRs) with 95% CIs. Between-group differences in layoff time were analyzed. Results: In total, 25,462 injuries were recorded, with 238 (0.9%) of these affecting the hand (71.4%; n = 170), wrist (16.8%; n = 40), and forearm (11.8%; n = 28), producing an incidence of 0.065 injuries per 1000 hours. A majority of the injuries were traumatic with an acute onset (98.7%; n = 235). Fractures were the most common injuries recorded (58.8%; n = 140), often involving the metacarpal bones (25.2%; n = 60) and phalanges (10.1%; n = 24). The injury incidence was significantly higher for goalkeepers (115 injuries; 0.265 per 1000 hours) compared with outfield players (123 injuries; 0.038 per 1000 hours) (RR, 7.0 [95% CI, 5.4-9.0]). Goalkeepers also had a significantly longer mean layoff time than outfield players (23 ± 27 vs 15 ± 27 days; P = .016). Conclusion: Injuries to the hand, wrist, and forearm constituted less than 1% of all time-loss injuries in male professional soccer players. Fractures were most common and constituted more than half of all injuries. Goalkeepers had a 7-fold higher incidence and an over 1-week longer mean layoff time compared with outfield players.
