The presence and predictive capacity of altered cervical kinematics, neuromuscular, and psychological features in individuals with whiplash associated disorders at different stages of pain
Neck pain is a significant source of disability and is associated with reduced quality of life and reduced work productivity. Besides the burden of current neck pain, neck pain disorders are commonly recurring conditions, with episodes of pain reoccurring over the course of months or years. Individuals with Whiplash Associated Disorders (WAD) are more likely to present with higher pain severity and greater physical and psychological impairments than individuals with idiopathic neck pain.
This thesis presents an investigation of features related to cervical kinematic, neuromuscular, and psychological function in individuals with acute, recurrent, and chronic neck pain (CNP) following a whiplash trauma, and assesses their relevance for the presence of persistent pain and disability. Four studies were conducted to investigate this aim.
Study 1 assessed cervical kinematic features in people with acute WAD and assessed their correlations with self-reported outcomes. Compared to healthy participants, cervical range of motion, velocity of movement, and smoothness of movement were altered in people with acute WAD and the extent of these features were associated with the level of neck pain and disability.
Study 2 comprised a systematic review to assess whether the cervical kinematic features identified in Study 1 were predictive of ongoing pain and disability after a whiplash trauma. Low to very low-quality evidence indicates that high levels of pain and disability at baseline as well as a higher WAD grade were associated with poor outcomes. Inconclusive evidence was found on the predictive capacity of neck range of motion, joint position error, activity of the superficial neck muscles, muscle strength/endurance, and perceived functional capacity. No primary studies investigated the association between more contemporary kinematic features such as velocity of neck movement, smoothness of movement, and variability of neck motion with ongoing disability following a whiplash injury. Findings from this review prompted the need for Study 3.
The initial aim of Study 3 was to investigate the predictive ability of cervical kinematic features on pain and disability six months following a whiplash injury. However, this aim was modified due to the small sample of recruited participants as a consequence of the COVID-19 pandemic. The modified aim was to assess the correlation between baseline measures of cervical kinematics and ongoing pain and disability six months later, instead of assessing the predictive ability of such features. Preliminary findings suggest that cervical kinematics in extension were correlated with ongoing pain and disability six months following the injury.
The final study, Study 4, of the thesis investigated similar features that were assessed in the other studies within this thesis, but in individuals with recurrent neck pain (RNP), or CNP following a whiplash injury, and healthy participants. All three groups had been assessed at baseline, with only the RNP group had been followed for up to a 12-months. The existence of altered cervical kinematic features, neuromuscular, and psychological function in individuals with RNP compared to CNP and healthy participants was assessed (cross-sectional design), with their predictive ability investigated in those with RNP (longitudinal design). The results indicated that people with RNP and CNP presented with higher neck disability, greater kinesiophobia, lower quality of life, slower and irregular neck movements, and less neck strength compared to healthy controls. Moreover, a higher number of previous pain episodes within the last 12 months along with lower neck flexion strength were predictive of higher neck disability at a six-month follow-up in those with RNP. These findings have significant implications for rehabilitation and prevention of patients with WAD; this work has identified features which could be targeted in a rehabilitation programme with the aim of preventing recurrent episodes of neck pain.
Overall, this thesis found that altered cervical kinematics together with impaired psychological function are present soon after a whiplash injury and can remain present in people with CNP, and in people with RNP even when assessed during a pain-free period. Furthermore, preliminary findings highlighted the association between altered cervical extension with ongoing pain and disability following a whiplash trauma, and that the number of previous episodes of neck pain over a 12-month period together with lower neck muscle strength were predictive of higher neck disability at a six-month follow up in people with RNP. Greater understanding of the physical and psychological manifestations at different stages of pain and their relevance to ongoing poor outcomes has potential to influence rehabilitation programmes to ensure better patient recovery
Are physical factors associated with poor prognosis following a whiplash trauma?:A protocol for a systematic review and data synthesis
Introduction: Mitigating the transition from acute to chronic whiplash-associated disorders (WAD) is fundamental, and this could be achieved through early identification of individuals at risk. Several physical factors such as angular velocity, smoothness of neck movement and coactivation of neck flexors and extensors, have been observed in patients with WAD, but their predictive ability after a whiplash injury have not been considered in previous reviews. Therefore, the aim of the current protocol is to outline the protocol for a systematic review that synthesises the current evidence of which physical factors can predict ongoing pain and disability following a whiplash trauma. Methods and analysis: Two independent reviewers will search for studies in several electronic databases including MEDLINE, Embase, CINAHL, PsycINFO, Scopus and Web of Science as well as grey literature. Observational cohort studies will be considered if they involve participants with acute WAD followed for at least 3 months post-injury. Studies will be required to assess the prognostic ability of one or more physical factors that directly involve a body function and/or structure and can be measured objectively. Further, patient-reported outcomes of physical function will be considered. The primary outcome for this review is Neck Disability Index, while all other validated measures will be considered as secondary outcomes. Risk of bias across individual studies will be assessed using the Quality In Prognostic Studies tool along with the Grades of Recommendation, Assessment, Development and Evaluation method to assess the quality of evidence. A meta-analysis will be conducted depending on homogeneity and the number of available studies. If appropriate, data will be pooled and presented as odds ratios, otherwise, a qualitative synthesis will be conducted. Ethics and dissemination: Ethical approval is not required for this systematic review. The result from this review will be published in peer-reviewed journals.

Do measures of physical function enhance the prediction of persistent pain and disability following a whiplash injury?:Protocol for a prospective observational study in Spain
INTRODUCTION: Not all factors that predict persistent pain and disability following whiplash injury are known. In particular, few physical factors, such as changes in movement and muscle behaviour, have been investigated. The aim of this study is to identify predictive factors that are associated with the development of persistent pain and disability following a whiplash injury by combining contemporary measures of physical function together with established psychological and pain-related predictive factors.METHODS AND ANALYSIS: A prospective observational study will recruit 150 consecutive eligible patients experiencing whiplash-related symptoms, admitted to a private physiotherapy clinic in Spain within 15 days of their whiplash injury. Poor outcome will be measured using the Neck Disability Index (NDI), defined as an NDI score of 30% or greater at 6 months post injury. Candidate predictors, including demographic characteristics, injury characteristics, pain characteristics, self-reported psychosocial factors and physical factors, will be collected at baseline (within 15 days of inception). Regression analyses will be performed to identify factors that are associated with persistent neck pain and disability over the study period.ETHICS AND DISSEMINATION: The project has been approved by the Ethics Committee of the province of Malaga, Spain (#30052019). The results of this study will be published in peer-reviewed journals.</p
Laparoscopic Cholecystectomy (LC) and the Risk Factors in the Conversion to Open Cholecystectomy (OC) Surgery: Jordan Statistical Review
This study aimed at exploring the risk factors in the conversion from laparoscopic cholecystectomy (LC) to open cholecystectomy (OC) Surgery, and overview the Jordanian statistics for patients over the year 2016 in the Jordanian hospitals. Results show that male gender with symptomatic cholelithiasis was associated with higher conversion rates. And results also showed that the age (>65 years) to be a risk factor for increased perioperative morbidity and conversion rates because of associated acute cholecystitis. Laparoscopic cholecystectomy is a safe procedure in patients, with no increased risk of complications compared with the open procedure. The recovery is faster and the hospital stay, shorter
A network analysis reveals the interaction between fear and physical features in people with neck pain.
Although neck pain is known to be a complex and multifactorial condition characterised by the interplay between physical and psychological domains, a comprehensive investigation examining the interactions across multiple features is still lacking. In this study, we aimed to unravel the structure of associations between physical measures of neuromuscular function and fear of movement in people with a history of neck pain. One hundred participants (mean age 33.3 ± 9.4) were assessed for this cross-sectional study, and the neuromuscular and kinematic features investigated were the range of motion, velocity of neck movement, smoothness of neck movement, neck proprioception (measured as the joint reposition error), and neck flexion and extension strength. The Tampa Scale for Kinesiophobia was used to assess fear of movement. A network analysis was conducted to estimate the associations across features, as well as the role of each feature in the network. The estimated network revealed that fear of movement and neuromuscular/kinematic features were conditionally dependent. Higher fear of movement was associated with a lower range of motion, velocity, smoothness of neck movement, neck muscle strength, and proprioception (partial correlations between - 0.05 and - 0.12). Strong interactions were also found between kinematics features, with partial correlations of 0.39 and 0.58 between the range of motion and velocity, and between velocity and smoothness, respectively. The velocity of neck movement was the most important feature in the network since it showed the highest strength value. Using a novel approach to analysis, this study revealed that fear of movement can be associated with a spectrum of neuromuscular/kinematic adaptations in people with a history of neck pain

Does Pain Extent Predict Ongoing Pain and Disability in Patients with Chronic Whiplash-Associated Disorders?
This study investigates whether baseline pain extent, extracted from an electronic pain drawing, is an independent predictive factor of pain and disability measured 1 year and 2 years later in people with chronic WAD. Participants completed questionnaires assessing neck pain intensity, disability via the Neck Disability Index (NDI), psychological features, and work ability. Participants also completed electronic pain drawings from which their pain extent was extracted. A two-step modelling approach was undertaken to identify the crude and adjusted association between pain extent and NDI measured at 1-year and 2-year follow-ups. A total of 205 participants were included in the analysis. The univariate analysis showed that pain extent was significantly associated with the NDI score at the 1-year (p = 0.006, 95% CI: 0.159-0.909) and 2-year (p = 0.029, 0.057-0.914) follow-ups. These associations were not maintained when we introduced perceived disability, psychological health, and work ability into the model after 1 year (p = 0.56, 95%CI: -0.28-0.499) and 2 years (p = 0.401, -0.226-0.544). Pain extent, as an independent factor, was significantly associated with perceived pain and disability in patients with chronic WAD for up to 2 years. This association was masked by neck disability, psychological health, and work ability
Post-Transplant Diabetes Mellitus in Renal Transplant Recipients, Single-Centre Data: Incidence, Risk Factors, and Effect on Graft Function and Mortality
Background: De novo post-transplant diabetes mellitus (PTDM) is a frequent complication among renal transplant recipients; it confers a high risk for graft failure and patient mortality. This single-centre study aimed to determine the incidence and risk factors of PTDM and its effects on graft outcome and mortality. Methods: In a single-centre longitudinal cohort analysis of 383 non-diabetic renal transplant follow-up recipients, outcomes were analysed through a detailed chart review. We hypothesized that different donor and recipient characters such as age, gender, and HLA mismatch would affect PTDM development in renal transplant recipients. PTDM is defined on basis of fasting plasma sugar (≥7 mmol/L or ≥126 mg/dL), random plasma sugar (≥11.1 mmol/L or ≥200 mg/dL), and glycated haemoglobin (HBA1C: >6.5% or 48 mmol/mol). We assessed PTDM incidence, risk factors, and its effect on patient mortality and graft outcome using Cox regression. Results: The mean age at the time of transplantation was 35.70 (±14.27) years, and 50.91% were male. PTDM incidence in the study period was 23.30%. Independent risk factors include older age at the time of transplantation, cyclosporine immunosuppression, cytomegalovirus, and hepatitis C virus infection. PTDM is not associated with graft dysfunction, whereas it significantly carries high mortality. Conclusion: PTDM is common among renal transplant recipients. Older age at the time of transplantation, cyclosporine immunosuppression, cytomegalovirus, and hepatitis C virus are risk factors. PTDM carries high mortality but is not associated with graft failure
Twelve-month observational study of children with cancer in 41 countries during the COVID-19 pandemic
Introduction Childhood cancer is a leading cause of death. It is unclear whether the COVID-19 pandemic has impacted childhood cancer mortality. In this study, we aimed to establish all-cause mortality rates for childhood cancers during the COVID-19 pandemic and determine the factors associated with mortality. Methods Prospective cohort study in 109 institutions in 41 countries. Inclusion criteria: children <18 years who were newly diagnosed with or undergoing active treatment for acute lymphoblastic leukaemia, non-Hodgkin's lymphoma, Hodgkin lymphoma, retinoblastoma, Wilms tumour, glioma, osteosarcoma, Ewing sarcoma, rhabdomyosarcoma, medulloblastoma and neuroblastoma. Of 2327 cases, 2118 patients were included in the study. The primary outcome measure was all-cause mortality at 30 days, 90 days and 12 months. Results All-cause mortality was 3.4% (n=71/2084) at 30-day follow-up, 5.7% (n=113/1969) at 90-day follow-up and 13.0% (n=206/1581) at 12-month follow-up. The median time from diagnosis to multidisciplinary team (MDT) plan was longest in low-income countries (7 days, IQR 3-11). Multivariable analysis revealed several factors associated with 12-month mortality, including low-income (OR 6.99 (95% CI 2.49 to 19.68); p<0.001), lower middle income (OR 3.32 (95% CI 1.96 to 5.61); p<0.001) and upper middle income (OR 3.49 (95% CI 2.02 to 6.03); p<0.001) country status and chemotherapy (OR 0.55 (95% CI 0.36 to 0.86); p=0.008) and immunotherapy (OR 0.27 (95% CI 0.08 to 0.91); p=0.035) within 30 days from MDT plan. Multivariable analysis revealed laboratory-confirmed SARS-CoV-2 infection (OR 5.33 (95% CI 1.19 to 23.84); p=0.029) was associated with 30-day mortality. Conclusions Children with cancer are more likely to die within 30 days if infected with SARS-CoV-2. However, timely treatment reduced odds of death. This report provides crucial information to balance the benefits of providing anticancer therapy against the risks of SARS-CoV-2 infection in children with cancer
Global overview of the management of acute cholecystitis during the COVID-19 pandemic (CHOLECOVID study)
Background: This study provides a global overview of the management of patients with acute cholecystitis during the initial phase of the COVID-19 pandemic. Methods: CHOLECOVID is an international, multicentre, observational comparative study of patients admitted to hospital with acute cholecystitis during the COVID-19 pandemic. Data on management were collected for a 2-month study interval coincident with the WHO declaration of the SARS-CoV-2 pandemic and compared with an equivalent pre-pandemic time interval. Mediation analysis examined the influence of SARS-COV-2 infection on 30-day mortality. Results: This study collected data on 9783 patients with acute cholecystitis admitted to 247 hospitals across the world. The pandemic was associated with reduced availability of surgical workforce and operating facilities globally, a significant shift to worse severity of disease, and increased use of conservative management. There was a reduction (both absolute and proportionate) in the number of patients undergoing cholecystectomy from 3095 patients (56.2 per cent) pre-pandemic to 1998 patients (46.2 per cent) during the pandemic but there was no difference in 30-day all-cause mortality after cholecystectomy comparing the pre-pandemic interval with the pandemic (13 patients (0.4 per cent) pre-pandemic to 13 patients (0.6 per cent) pandemic; P = 0.355). In mediation analysis, an admission with acute cholecystitis during the pandemic was associated with a non-significant increased risk of death (OR 1.29, 95 per cent c.i. 0.93 to 1.79, P = 0.121). Conclusion: CHOLECOVID provides a unique overview of the treatment of patients with cholecystitis across the globe during the first months of the SARS-CoV-2 pandemic. The study highlights the need for system resilience in retention of elective surgical activity. Cholecystectomy was associated with a low risk of mortality and deferral of treatment results in an increase in avoidable morbidity that represents the non-COVID cost of this pandemic
