Effect of structured diet with exercise education on anthropometry and lifestyle modification in patients with type 2 diabetes: A 12-month randomized clinical trial.

AIMS: Lifestyle modification involving active engagement of specialised dietitian with diet and exercise education, can be effective as first-line treatment for diabetes. METHODS: 192 patients were enrolled with diabetes in a randomised controlled trial and followed up for one year. Ninety-four patients in the intervention group participated in a comprehensive structured diet and exercise education conducted by a specialised dietitian at ambulatory centre in the United Arab Emirates. RESULTS: The mean difference in the change in body mass index between study groups at study exit and baseline was statistically significant (BMI difference = -1.86, 95 % CI -2.68 - -1.04, P < 0.01). The intervention group reported significant decrease in total carbohydrate and daily energy intake compared to baseline (173.7 g vs 221.1 g and 1828.5 kcal vs 2177.9 kcal, respectively). Moreover, the mean metabolic equivalents (METs) in the intervention group increased significantly at study exit from baseline compared to control group METs, with mean difference between all between-group differences after baseline of 0.63 (95 % 0.29 - 0.97, P < 0.01). CONCLUSIONS: Structured diet and exercise counselling by specialised dietitian in ambulatory settings significantly reduced carbohydrate and daily energy intake, with improved anthropometric measurements and physical activity.

Post-natal steroid exposure in very low birthweight neonates and associations with acute kidney injury.

OBJECTIVE: The relationship between adrenal insufficiency (AI), post-natal steroids (PNS) and neonatal acute kidney injury (AKI) remains understudied. We investigated associations between PNS and AKI in very low birthweight (VLBW) neonates, hypothesizing PNS is associated with reduced AKI. STUDY DESIGN: We conducted a single-center retrospective review of VLBW infants comparing those with and without PNS exposure. Associations between PNS exposure and AKI were evaluated using generalized linear mixed-modeling adjusted for confounders. RESULT: Of 567 neonates, 97 (17.1%) were exposed to PNS and 130 (22.9%) experienced AKI. Infants with PNS had lower gestational age, birthweight, Apgar scores, and experienced more AI versus those without PNS (all p < 0.05). PNS was associated with AKI (aRR 1.72, 95% CI 1.09-2.72) though hydrocortisone alone was not. CONCLUSION: PNS exposure, but not hydrocortisone alone, is associated with increased AKI in VLBW neonates. Further analysis is needed to investigate the role of AI and AKI.

The Prevalence and Influence of New or Worsened Neck Pain After a Sport-Related Concussion in Collegiate Athletes: A Study From the CARE Consortium.

BACKGROUND: Neck pain in a concussion population is an emerging area of study that has been shown to have a negative influence on recovery. This effect has not yet been studied in collegiate athletes. HYPOTHESIS: New or worsened neck pain is common after a concussion (>30%), negatively influences recovery, and is associated with patient sex and level of contact in sport. STUDY DESIGN: Cohort study; Level of evidence, 2. METHODS: Varsity-level athletes from 29 National Collegiate Athletic Association member institutions as well as nonvarsity sport athletes at military service academies were eligible for enrollment. Participants completed a preseason baseline assessment and follow-up assessments at 6 and 24 to 48 hours after a concussion, when they were symptom-free, and when they returned to unrestricted play. Data collection occurred between January 2014 and September 2018. RESULTS: A total of 2163 injuries were studied. New or worsened neck pain was reported with 47.0% of injuries. New or worsened neck pain was associated with patient sex (higher in female athletes), an altered mental status after the injury, the mechanism of injury, and what the athlete collided with. The presence of new/worsened neck pain was associated with delayed recovery. Those with new or worsened neck pain had 11.1 days of symptoms versus 8.8 days in those without (P < .001). They were also less likely to have a resolution of self-reported symptoms in ≤7 days (P < .001). However, the mean duration of the return-to-play protocol was not significantly different for those with new or worsened neck pain (7.5 ± 7.7 days) than those without (7.4 ± 8.3 days) (P = .592). CONCLUSION: This novel study shows that neck pain was common in collegiate athletes sustaining a concussion, was influenced by many factors, and negatively affected recovery.

Phase I-II Trial of Early Azacitidine after Matched Unrelated Donor Hematopoietic Cell Transplantation.

Graft-versus-host disease (GVHD) is a major complication after allogeneic hematopoietic cell transplantation (allo-HCT). The hypomethylating agent azacitidine (AZA) has been shown to be effective in preclinical and clinical studies for the prevention of acute GVHD (aGVHD). We sought to determine the maximum tolerated dose (MTD) of AZA when given on days 1 to 5 of a 28-day cycle for 4 cycles, starting on day +7 after allo-HCT, as well as its impact on aGVHD and chronic GVHD (cGVHD), relapse, and overall survival (OS) in patients undergoing matched unrelated donor allo-HCT. This study was a single-arm, single-center, open-label phase I-II study with a total of 15 and 38 patients enrolled in the phase I and II portions of the trial, respectively. A standard 3+3 study design was used in phase I, and all patients in phase II received AZA at the MTD determined in phase I. The MTD of AZA starting at day +7 post-transplantation was 45 mg/m2. Phase II of the study was halted after enrolling 38 of the planned 46 patients following an interim analysis that suggested futility. Overall, AZA at 45 mg/m2 exhibited a side effect profile consistent with prior reports and had a minimal impact on engraftment. The cumulative incidence of clinically significant aGVHD by day +180 was 39.9% (95% confidence interval [CI], 22% to 53.7%). The incidence of all-grade cGVHD was 61.4% (95% CI, 40.3% to 75%). At 1 year, OS was 73.7% (95% CI, 60.9% to 89.1%), and the disease relapse rate was 11.4% (95% CI, .2% to 21.3%). Our results suggest that early post-allo-HCT AZA has limited efficacy in preventing aGVHD and cGVHD but could have a beneficial effect in preventing disease relapse.

Towards a better understanding between non-Muslim primary care clinicians and Muslim patients: A literature review intended to reduce health care inequities in Muslim patients.

Although Muslims are a growing population within many non-Muslim countries, there are insufficient Muslim clinicians to care for them. Studies have shown that non-Muslim clinicians have limited knowledge and understanding of Islamic practices affecting health, which may lead to disparities in the quality of healthcare delivery and outcomes when caring for Muslim patients. Muslims come from many different cultures and ethnicities and have variations in their beliefs and practices. This literature review provides some insights which may strengthen therapeutic bonds between non-Muslim clinicians and their Muslim patients resulting in improved holistic, patient-centered care in the areas of cancer screening, mental health, nutrition, and pharmacotherapy. Additionally, this review informs clinicians about the Islamic perspective on childbirth, end of life issues, travel for Islamic pilgrimage, and fasting during the month of Ramadan. Literature was sourced by a comprehensive search in PubMed, Scopus, and CINAHL along with hand screening of citations. Title and abstract screening followed by full-text screening excluded studies including less than 30% Muslim participants, protocols, or reporting results deemed irrelevant to primary care. 115 papers were selected for inclusion in the literature review. These were grouped into the themes of general spirituality, which were discussed in the Introduction, and Islam and health, Social etiquette, Cancer screening, Diet, Medications and their alternatives, Ramadan, Hajj, Mental health, Organ donation and transplants, and End of life. Summarizing the findings of the review, we conclude that health inequities affecting Muslim patients can be addressed at least in part by improved cultural competency in non-Muslim clinicians, as well as further research into this area.

Emirates Heart Health Project (EHHP): A protocol for a stepped-wedge family-cluster randomized-controlled trial of a health-coach guided diet and exercise intervention to reduce weight and cardiovascular risk in overweight and obese UAE nationals.

INTRODUCTION: Cardiovascular disease (CVD) is the most common cause of death both globally and in the United Arab Emirates. Despite public health measures and health education, the rates of death from CVD remain stable. Barriers previously identified to lifestyle changes include cultural reasons, boredom, and lack of family support. The Emirates Heart Health Project (EHHP) seeks to support healthy lifestyle changes through a family-based intervention using a health coach and fitness tracker. METHODS AND ANALYSIS: The EHHP is a stepped-wedge cluster-randomized trial with each cluster comprised of members of an extended family. Eligible participants will be ≥ 18 years of age, with BMI ≥ 25, have Emirati citizenship and be able to give informed consent for study participation. The cluster will have 16 weekly teaching sessions in the participants' family home by a health coach who will review individual weight, diet and exercise (monitored by a wearable fitness tracker). The clusters will have pre-intervention assessments of their weight and CVD risk profile and enter the intervention in randomized order. Each cluster will have a post-intervention assessment of the same measures. The primary outcome is weight reduction from baseline. Secondary outcomes will include change in CVD risk factors such as systolic and diastolic blood pressure, hemoglobin A1c, total cholesterol, LDL cholesterol, HDL cholesterol and triglycerides, waist circumference, and BMI. A mixed linear model will be used for analysis, where the parameters measured at the end of each 16-week episode will be the outcome values. These will be analyzed such that baseline values (measured just prior to the start of an episode) will be fixed covariables. Random effects are the family units. This trial has been registered with the NIH at clinicaltrials.gov (NCT04688684) and is being reported using the SPIRIT (Standard Protocol Items: Recommendations for Interventional Trials) and TIDieR (Template for intervention description and replication) framework. TRIAL REGISTRATION: Clinicaltrials.gov NCT04688684.

The Benefits of Utilizing Continuous Glucose Monitoring of Diabetes Mellitus in Primary Care: A Systematic Review.

BACKGROUND: Continuous glucose monitoring (CGM) and intermittently scanned CGM (is-CGM) have shown to effectively manage diabetes in the specialty setting, but their efficacy in the primary care setting remains unknown. Does CGM/is-CGM improve glycemic control, decrease rates of hypoglycemia, and improve staff/physician satisfaction in primary care? If so, what subgroups of patients with diabetes are most likely to benefit? METHODS: A comprehensive search in seven databases was performed in June 2021 for primary studies examining any continuous glucose monitoring system in primary care. We excluded studies with fewer than 20 participants, specialty care only, or hospitalized participants. The National Heart, Lung and Blood Institute and Grading of Recommendations Assessment, Development and Evaluation were used for the quality assessment. The weighted mean difference (WMD) of HbA1c between CGM/is-CGM and usual care with 95% confidence interval was calculated. A narrative synthesis was conducted for change of time in, above, or below range (TIR, TAR, and TBR) hypoglycemic events and staff/patient satisfaction. RESULTS: From ten studies and 4006 participants reviewed, CGM was more effective at reducing HbA1c compared with usual care (WMD -0.43%). There is low certainty of evidence that CGM/is-CGM improves TIR, TAR, or TBR over usual care. The CGM can reduce hypoglycemic events and staff/patient satisfaction is high. Patients with intensive insulin therapy may benefit more from CGM/is-CGM. CONCLUSIONS: Compared with usual care, CGM/is-CGM can reduce HbA1c, but most studies had notable biases, were short duration, unmasked, and were sponsored by industry. Further research needs to confirm the long-term benefits of CGM/is-CGM in primary care.

COVID-19 Infectious Disease Prevention and Mitigation Practices by Chiropractic Physicians and Licensed Massage Therapists in Mississippi: A Needs Assessment to Inform Health Education and Promotion.

Objective: The purpose of this study was to assess self-reported infection prevention processes and their effect on businesses of chiropractic doctors (DCs) and licensed massage therapists (LMTs) in Mississippi during the COVID-19 pandemic. Methods: We developed a survey that was electronically delivered to all licensed DCs and LMTs in Mississippi between August and September 2020. Assessments were made using Qualtrics software, with data management and subsequent analysis including Pearson's χ2 test. Results: Responses were based on 32 of 323 DCs and 69 of 934 LMTs that were still seeing patients through the pandemic (n = 101, response rate 8%). The DC and LMT practitioners (94%) used treatment table and/or surface sanitizing (91.8%) and hand washing and/or sanitizing (89.8%) between all patients. Female practitioners reported practicing handwashing for at least 20 seconds, whereas male practitioners reported practicing handwashing for at least 15 seconds (P < .001). DCs were more likely to report using gloves for personal protective equipment, and LMTs were more likely to report using face masks (P < .001). Other COVID-19 procedures included limiting practice to acute care (82.5%), checking all patient temperatures (62.9%), sign-in and wait in the car (53.2% LMT vs 6.5% DC, P < .001), and prohibiting all nonpatient visitors (87.7% LMTs vs 9.4% DCs, P < .001). DCs (96.9%) and LMTs (89.9%) reported making referrals for COVID-19 testing or treatment when indicated. LMTs (82.3%) reported seeing fewer patients (P = .03), and older practitioners reported the most economic impact (P = .003) by the pandemic. Patient concerns and LMTs needing more time to perform infection control (P = .04) were reasons cited by practitioners for the reduced number of visits seen. Conclusion: Most respondents had moderate to high compliance with guidelines on recommended infection prevention processes during fall 2020 of the COVID-19 pandemic. This assessment of compliance may be used to help guide future health education and promotion research of disease prevention and mitigation as well as physical and economic burdens faced by DCs and LMTs in Mississippi during a pandemic.

Integrating Engineering With Nature® strategies and landscape architecture techniques into the Sabine-to-Galveston Coastal Storm Risk Management Project.

Damaging storm events frequently impact the Texas coast. In response, the US Army Corps of Engineers Galveston District (SWG) has undertaken the Sabine-to-Galveston (S2G) Coastal Storm Risk Management (CSRM) Project. This approximately $3.9B project includes numerous measures across several counties of the upper Texas coast, including levees, floodwalls, and pump stations. In June 2019, SWG leadership enlisted a team including the paper authors to integrate Engineering With Nature (EWN) strategies into this infrastructure project. EWN strategies intentionally align natural and engineering processes to efficiently and sustainably deliver economic, environmental, and social benefits through collaboration. The first step in this process was to develop potentially relevant EWN strategies. A collaborative workshop included visits to project sites and working sessions where the project team reviewed challenges associated with each site, generated an array of EWN strategies, and began to test design concepts based on those strategies through collaborative drawing sessions. Afterward, prioritized ideas were refined and evaluated in terms of property acquisition, estimated cost, logistics, stakeholder and sponsor interest, constructability, aesthetics, recreational opportunities, and ecological benefit. Design concepts considered feasible for integration into the broader S2G project included horizontal levees, inland floodwater storage areas that double as wildlife habitat, and strategic placement of sediment berms to reduce storm impacts and provide marsh substrate. All these concepts should achieve intended CSRM outcomes while enhancing environmental and social benefits. This assimilation of EWN strategies and landscape architecture techniques into a large CSRM study illustrates a method for expanding overall project value and producing infrastructure that benefits coastal communities.

A framework for evaluating island restoration performance: A case study from the Chesapeake Bay.

The use of natural habitats for coastal protection (also known as Nature-Based Solutions or NBS) in place of engineered structures like breakwaters and seawalls can yield a wide range of ecological and economic benefits. Despite these advantages, NBS are not commonly implemented for shoreline protection due to uncertainty over the amount of protection afforded by each unique feature and how protective capacity and ecological benefits are likely to change over time as NBS mature and adapt to changing environmental drivers. Here, we highlight the recent restoration of Swan Island in the Chesapeake Bay, Maryland, USA, and the collaborative approach used to evaluate post-construction performance, as a framework for quantitative evaluation of NBS projects. At Swan Island, 60 000 cubic yards of dredged sediment were used to elevate and restore the island's footprint with an emphasis on increasing its protective and ecological benefits and long-term resilience to sea-level rise. Five entities have leveraged resources to quantify the benefits and efficacy of island restoration by conducting pre- and post-restoration monitoring, which supports the development of an integrated, simulation model that includes three "measured" system parameters: wave height, vegetative biomass, and island profile (i.e., elevations). The model will be used to predict island performance under a range of different system scenarios and used to inform adaptive management options. Results will demonstrate the efficacy of leveraging natural and engineered processes to restore island systems while providing a framework for quantifying NBS.

Incidence of Neck Pain in Patients With Concussion in a Pediatric Emergency Department.

OBJECTIVES: The aims of the study were (1) to determine the frequency of neck pain in patients diagnosed with mild traumatic brain injury (mTBI) or concussion in a pediatric level 1 trauma center emergency department (ED), (2) to identify variables associated with neck pain in this population, and (3) to report on aspects of care received in the ED including imaging and medication use. METHODS: This is a retrospective chart review of 652 patients presenting to a pediatric ED with diagnosis of concussion/mTBI. Charts were reviewed for the following information: baseline demographic information, mechanism of injury, cause of mTBI, presence or absence of neck pain, point tenderness in the neck on physical examination, and whether the patient followed up within our health system in the 6 months after injury. Charts were also reviewed for other concussion-related symptoms, medication given in the ED, imaging performed in the ED, cervical spine clearance in the ED, and referrals made. For those patients who did have follow-up appointments within our system, additional chart review was performed to determine whether they sought follow-up treatment for symptoms related to concussion/neck pain and the duration of follow-up. Statistical analyses focused on the prevalence of neck pain in the sample. We subsequently explored the degree to which neck pain was associated with other collected variables. RESULTS: Of 652 patients, 90 (13.8%) reported neck pain. Acceleration/deceleration injury and motor vehicle accident were predictive of neck pain. Neck pain was less common in those reporting nausea and vomiting. Direct impact of the head against an object was associated with reduced odds of neck pain, but after adjusting for other variables, this was no longer statistically significant. Patients with neck pain were older than those without neck pain. Patients with neck pain were more likely to receive ibuprofen or morphine and undergo imaging of the spine. They were also more likely to receive a referral and follow-up with neurosurgery. There was no significant difference between groups with respect to concussion-related follow-up visits or follow-up visits to a dedicated concussion clinic. CONCLUSIONS: Neck pain is a common symptom in pediatric patients with mTBI, although it was more likely in older patients and those presenting with acceleration/deceleration mechanisms. Although patients with neck pain were more likely to receive a referral and follow-up with neurosurgery, they were not more likely to have concussion-related follow-up visits. Indeed, most patients had no follow-up visits related to their concussion, which supports the notion that concussion is a self-limiting condition.

Advancing nature-based solutions by leveraging Engineering With Nature® strategies and landscape architectural practices in highly collaborative settings.

The US Army Corps of Engineers (USACE)'s Engineering With Nature® (EWN® ) initiative consistently promotes the use of collaboration for identifying innovative, nature-based solutions (NBS) that lead to more resilient communities and water-based infrastructure. In recent years, EWN researchers, in partnership with landscape architects (LAs) affiliated with the Dredge Research Collaborative (DRC), have championed an innovative, collaborative strategy that offers traditional planners an opportunity to participate in visioning exercises during the initial phases of coastal storm risk management projects. This has resulted in the identification, development, and incorporation of design concepts that prioritize NBS and the placement of natural and nature-based features (NNBF). These concepts, and their development process, have been documented in reports for the use of both the participating planners and other audiences interested in innovative NNBF. Upon observing these favorable outcomes, it has become clear that the integration of disciplines-landscape architecture, applied science, and engineering-has increased our ability to process, utilize, and communicate complex information. Both groups (i.e., DRC's LAs and EWN engineers and scientists) have considerable experience related to infrastructure design and performance; they elucidate ways to achieve functional engineering criteria while also maximizing ecological value and/or promoting more recreational opportunities. However, this partnership also produces a complementary set of uniquely acquired skills and expertise, which advances the development of NBS through accelerated and more meaningful communications. This study will offer insight into the partnership, collaborative techniques, and resulting products that have fostered innovation as well as advocacy for more sustainable infrastructure.

Beneficial use of dredged sediment as a sustainable practice for restoring coastal marsh habitat.

Coastal Louisiana (USA) continues to sustain immense land and habitat losses due to subsidence, sea-level rise, and storm events. Approximately 65 million m3 (85 million cubic yards) of sediment is dredged annually from Gulf Coast federal navigation channels to maintain safe waterway passage. The beneficial use of these sediments continues to increase, and now this sediment is recognized as a critical resource in large-scale (estimated multibillion dollar) ecosystem restoration efforts to mitigate land and habitat losses along the US Gulf Coast. However, the documentation of restoration benefits where dredged sediments are the primary resource is lacking, which limits the potential for future applications. Therefore, this study documents the progress to restore marsh habitat and the resultant benefits in West Bay, Louisiana, and investigates how the restoration practices align with principles of the US Army Corps of Engineers (USACE) Engineering with Nature® (EWN® ) and UN Sustainable Development Goals (UN SDGs). West Bay, a 4964-ha subdelta adjacent to the Mississippi River, typifies risks of coastal land loss that also threatens the integrity of the adjacent federal navigation channel. To help restore coastal marsh habitat on a large spatial and temporal scale, the USACE constructed an uncontrolled diversionary channel from the Mississippi River and with subsequent direct and strategic placement of dredged sediment. Restoration performance was assessed through remotely sensed methods using data spanning approximately 70 years. To date, placement of dredged sediment in the bay has facilitated the creation of over 800 ha of new land in the formerly open waters of West Bay. The West Bay restoration project aligns with the principles of the EWN initiative, which supports more sustainable practices to deliver economic, environmental, and social benefits through collaborative processes and meaningfully integrates 10 of the UN SDGs designed to achieve a better and more sustainable future.

Spinal manipulative therapy and cervical artery dissection: A retrospective comparison with spontaneous, traumatic, and iatrogenic etiologies at a single academic medical center.

OBJECTIVE: Cervical artery dissection (CAD) has been associated with spinal manipulative therapy (SMT). Although uncommonly reported, SMT-associated CADs hold devastating neurological consequences, warranting further exploration. We endeavored to investigate this association through the comparison of all CAD etiologies at a single academic medical center. METHODS: A retrospective chart review was conducted of patients diagnosed with CAD or transferred to our institution for primary management of CAD during the 10-year period from 2010 to 2020 (n = 578). Patients were divided into SMT-associated (within 1 month of presentation), spontaneous, traumatic, and iatrogenic cohorts. RESULTS: SMT-associated dissections represented 23/578 (4%) of all dissections and 5.9% of vertebral artery dissections specifically. These patients were generally younger than those in the spontaneous (p = .004) and iatrogenic groups (p < .001), and more often non-smokers or former smokers compared to the spontaneous (p = .009), traumatic (p = .001), and iatrogenic (p = .008) groups. Additionally, the SMT group had a higher mean low-density lipoprotein (LDL) than the spontaneous (p = .009) and traumatic (p = .003) types. SMT-associated CADs were more often vertebral and bilateral, compared to the spontaneous (p = .003; p < .001), traumatic (p = .047; p = .004), and iatrogenic (p = .002; p = .002) groups. Outcomes including infarct (p = .112), medical treatment (p = .523), intervention (p = .47), and length of stay (p = .512) were similar between the SMT and spontaneous groups. CONCLUSIONS: In this unique study comparing SMT-associated CADs with other dissection etiologies, SMT-associated CADs were uncommon and not associated with worse clinical outcomes. However, SMT-associated CADs were more likely to be bilateral and affected the vertebral arteries in young, non-smoking patients with high LDL.

Benefits of the addition of continuous or flash glucose monitoring versus standard practice using self-monitored blood glucose and haemoglobin A1c in the primary care of diabetes mellitus: a systematic review protocol.

INTRODUCTION: Studies demonstrate that optimal glycaemic control reduces morbidity from diabetes mellitus but remains elusive in a significant portion of patients. Although research shows that continuous glucose monitoring (CGM) and flash glucose monitoring (FGM) improves glycaemic control in selected subsets of patients with diabetes in specialty practices, we found no systematic reviews evaluating the use of CGM/FGM in primary care, where the majority of patients with diabetes are cared for.This systematic review aims to answer the questions: 'compared with usual care of self-monitoring blood glucose and haemoglobin A1c (HbA1c), does the addition of CGM/FGM use in the primary care of patients with diabetes improve glycaemic control, decrease rates of hypoglycaemia, and improve patient and physician satisfaction?' and if so, 'what subgroups of primary care patients with diabetes are most likely to benefit?'. METHODS AND ANALYSIS: Aligning with the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols guidelines, a search will be conducted in PubMed, EMBASE, Scopus, CINAHL, Cochrane Central Register of Controlled Trials and Web of Science. We will include studies investigating CGM/FGM use and reporting the primary outcome measure of HbA1c and secondary outcome measures of hypoglycaemia, time in range, time below range, time above range and patient/staff satisfaction. We will examine which patient populations appear to benefit from CGM/FGM. Three independent researchers will use the Covidence systematic review software for blinded screening and study selection. The National Heart, Lung, and Blood Institute quality assessment tool and Grading of Recommendations Assessment, Development and Evaluation will be used to assess the risk of bias and quality of evidence. ETHICS AND DISSEMINATION: The systematic review methodology does not require ethics approval due to the nature of the study design. Study findings will be publicly available to a wide readership across disciplines and will be published in a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42021229416.

Predictive Value of Creatinine-based Equations of Kidney Function in the Long-term Prognosis in United Arab Emirates Patients.

OBJECTIVES: Chronic kidney disease (CKD) is an independent predictor of mortality. Several creatinine-based equations are used to assess the estimated glomerular filtration rate or creatinine clearance and mortality prediction in various ethnic populations. Similarly, renal insufficiency is associated with poor prognosis of UAE nationals with cardiovascular disease (CVD) risk factors. However, the equation that best assesses prognosis among these patients is unknown. This study aimed to compare the prognostic abilities of different creatinine-based kidney function equations for predicting all-cause mortality in UAE nationals with vascular comorbidities. METHODS: This retrospective observational study analyzed 1186 patients (54.0% men) with CVD risk factors. Multivariable Cox regression analysis was used to evaluate the associations of categorical renal function stages with all-cause mortality. Measures of performance in each equation assessed with respect to all-cause mortality were evaluated and compared to the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equation by calculating the C-index, net reclassification index (NRI), and integrated discrimination index. RESULTS: Over a median follow-up of 8.9 years, the cumulative incidence of all-cause mortality was 9.4% (n = 112). After multivariable adjustment, the discriminative ability for all-cause mortality was significantly higher in the body surface area-adjusted Cockcroft-Gault (BSA-CG) formula than in the CKD-EPI equation (C-indices: 0.869 vs. 0.861, respectively, p = 0.037). NRI was significantly positive and favored the BSA-CG formula (0.54; 95% confidence interval: 0.35-0.64) compared to the CKD-EPI equation. CONCLUSIONS: Our findings suggest that the BSA-CG equation may have the potential to slightly improve mortality prediction compared to the CKD-EPI equation in UAE nationals with vascular risk. Further large multicenter studies are warranted to confirm our findings.

External validation and clinical usefulness of three commonly used cardiovascular risk prediction scores in an Emirati population: a retrospective longitudinal cohort study.

OBJECTIVES: Cardiovascular disease (CVD) risk prediction models are useful tools for identifying those at high risk of cardiovascular events in a population. No studies have evaluated the performance of such risk models in an Arab population. Therefore, in this study, the accuracy and clinical usefulness of two commonly used Framingham-based risk models and the 2013 Pooled Cohort Risk Equation (PCE) were assessed in a United Arab Emirates (UAE) national population. DESIGN: A 10-year retrospective cohort study. SETTING: Outpatient clinics at a tertiary care hospital, Al-Ain, UAE. PARTICIPANTS: The study cohort included 1041 UAE nationals aged 30-79 who had no history of CVD at baseline. Patients were followed until 31 December 2019. Eligible patients were grouped into the PCE and the Framingham validation cohorts. EXPOSURE: The 10-year predicted risk for CVD for each patient was calculated using the 2008 Framingham risk model, the 2008 office-based Framingham risk model, and the 2013 PCE model. PRIMARY OUTCOME MEASURE: The discrimination, calibration and clinical usefulness of the three models for predicting 10-year cardiovascular risk were assessed. RESULTS: In women, the 2013 PCE model showed marginally better discrimination (C-statistic: 0.77) than the 2008 Framingham models (C-statistic: 0.74-0.75), whereas all three models showed moderate discrimination in men (C-statistic: 0.69‒0.70). All three models overestimated CVD risk in both men and women, with higher levels of predicted risk. The 2008 Framingham risk model (high-risk threshold of 20%) classified only 46% of women who subsequently developed incident CVD within 10 years as high risk. The 2013 PCE risk model (high-risk threshold of 7.5%) classified 74% of men who did not develop a cardiovascular event as high risk. CONCLUSIONS: None of the three models is accurate for predicting cardiovascular risk in UAE nationals. The performance of the models could potentially be improved by recalibration.

Guideline summary review: an evidence-based clinical guideline for the diagnosis and treatment of low back pain.

BACKGROUND CONTEXT: The North American Spine Society's (NASS) Evidence Based Clinical Guideline for the Diagnosis and Treatment of Low Back Pain features evidence-based recommendations for diagnosing and treating adult patients with nonspecific low back pain. The guideline is intended to reflect contemporary treatment concepts for nonspecific low back pain as reflected in the highest quality clinical literature available on this subject as of February 2016. PURPOSE: The purpose of the guideline is to provide an evidence-based educational tool to assist spine specialists when making clinical decisions for adult patients with nonspecific low back pain. This article provides a brief summary of the evidence-based guideline recommendations for diagnosing and treating patients with this condition. STUDY DESIGN: This is a guideline summary review. METHODS: This guideline is the product of the Low Back Pain Work Group of NASS' Evidence-Based Clinical Guideline Development Committee. The methods used to develop this guideline are detailed in the complete guideline and technical report available on the NASS website. In brief, a multidisciplinary work group of spine care specialists convened to identify clinical questions to address in the guideline. The literature search strategy was developed in consultation with medical librarians. Upon completion of the systematic literature search, evidence relevant to the clinical questions posed in the guideline was reviewed. Work group members utilized NASS evidentiary table templates to summarize study conclusions, identify study strengths and weaknesses, and assign levels of evidence. Work group members participated in webcasts and in-person recommendation meetings to update and formulate evidence-based recommendations and incorporate expert opinion when necessary. The draft guideline was submitted to an internal and external peer review process and ultimately approved by the NASS Board of Directors.
