The Fragility of Statistical Findings in Cervical Disc Arthroplasty: a Systematic Review of Randomized Controlled Trials.

PURPOSE: This study employs both the fragility index (FI) and fragility quotient (FQ) to assess the level of robustness in the cervical disc arthroplasty (CDA) literature. We hypothesize that dichotomous outcomes involving CDA would exhibit statistical vulnerability. METHODS: A PubMed search was conducted to evaluate dichotomous data for randomized controlled trials (RCTs) in CDA literature from 2000 to 2023. The FI of each outcome was calculated through the reversal of a single outcome event until significance was reversed. The FQ was calculated by dividing each fragility index by the study sample size. The interquartile range (IQR) was also calculated for the FI and FQ. RESULTS: Of the 1561 articles screened, 111 met the search criteria, with 35 RCTs evaluating CDA included for analysis. Six hundred and ninety-three outcome events with 130 significant (P < 0.05) outcomes and 563 nonsignificant (P ≥ 0.05) outcomes were identified. The overall FI and FQ for all 693 outcomes were 5 (IQR 3-7) and 0.019 (IQR 0.011-0.043). Fragility analysis of statistically significant outcomes and nonsignificant outcomes both revealed an FI of 5. All of the studies reported loss to follow-up (LTF) data where 65.7% (23) did not report or reported an LTF greater or equal to 5. CONCLUSIONS: The literature regarding CDA RCTs lacks statistical robustness and may misrepresent the conclusions with the sole use of the P value. By implementing the FI and FQ along with the P value, we believe the interpretation and contextualization of the clinical data surrounding CDA will be better understood.

Overparenting and psychological wellbeing among Chinese adolescents: Findings based on latent growth modeling.

Although overparenting is a growing phenomenon across the globe, there is a severe lack of longitudinal studies examining the trajectory of overparenting and its effects on early adolescent development, particularly in non-Western contexts. The study collected three waves of longitudinal data from 1328 early Chinese adolescents in Hong Kong with an interval of 1 year to examine the stability and change of perceived paternal and maternal overparenting and their effects on adolescent psychological wellbeing. The results indicated that perceived paternal and maternal overparenting declined over time. Besides, adolescents reported lower anxiety and depressive symptoms when they perceived a steep decline in maternal overparenting. Adolescent anxiety at earlier time points also predicted a steeper decline in paternal and maternal overparenting trajectories respectively. Furthermore, we identified gender differences in the initial level of paternal overparenting and the trajectory of maternal overparenting, as well as the effects of rates of change of maternal overparenting on adolescent anxiety and depressive symptoms. The findings give support for self-determination theory and the separation-individuation model, suggesting that changes of overparenting may hinder adolescents' desires for autonomy and self-direction, which may increase their psychological morbidity. The study contributes to theoretical development of contemporary Chinese socialization models and provides useful pointers for future studies of overparenting.

Impact of COVID-19 on the Self-Report Assessment of Obsessive-Compulsive Disorder.

Background The COVID-19 pandemic and subsequent guidelines have had a substantial effect on social norms. This likely affected self-report assessment of psychopathology, namely those that assess obsessive-compulsive tendencies routinely used to screen for obsessive-compulsive disorder (OCD). It was hypothesized that self-report assessment of OCD likely produces inflated, non-discriminating scale scores. Methods Data collection occurred prior to the COVID-19 pandemic with the aim of validating a new psychological test; however, data collection was abruptly halted in March 2020. Data collection was allowed to resume in the latter half of the year. Both groups were racio-ethnically and gender diverse. Results Self-report measures of OCD yielded inflated scores. For instance, the total obsessive-compulsive inventory-revised (OCI-R) average score of all participants went from normative levels prior to COVID-19 (M = 13.69, SD = 10.32) to an average score that was above the clinical cut-off on the OCI-R (M = 32.89; SD = 12.95) during the pandemic (t(135) = 9.66, p < 0.001, Cohen's d = 1.66). Conclusions OCD-related scale scores likely produced false positives in research and practice due to COVID-19 health guidelines put in place to protect against infection that may otherwise be considered contamination fears on OCD measures.

Filial responsibilities and psychological wellbeing among Chinese adolescents in poor single-mother families: does parental warmth matter?

Introduction: Adolescent children raised in single-mother households, particularly those living in poverty, often need to assume more instrumental and emotional familial responsibilities to cope with family challenges. Method: This study examined the relationships between these filial responsibilities and adolescent psychological wellbeing, as well as the moderating effect of maternal warmth on these relationships via survey. The sample comprised 325 Chinese adolescent children (43.3% girls; Mage = 13.5) from economically disadvantaged single-mother families in Hong Kong. Results: The results indicated that adolescents' instrumental filial responsibilities were positively associated with their life satisfaction. Emotional filial responsibilities, on the other hand, were positively linked to life satisfaction and negatively associated with depression. Furthermore, maternal warmth was found to moderate the relationship between emotional filial responsibilities and life satisfaction. Adolescents who perceived higher levels of maternal warmth and performed more emotional filial responsibilities reported greater life satisfaction than those who performed fewer such responsibilities. Furthermore, the moderating effect of maternal warmth on the relationship between instrumental filial responsibilities and life satisfaction varied between boys and girls. Additionally, the age of the adolescent moderated the effect of maternal warmth on the relationship between emotional filial responsibilities and adolescent anxiety. Discussion: These findings suggest that filial responsibilities do not necessarily impede adolescent wellbeing. Instead, maternal warmth appears to be a crucial family factor that influences the nature of the relationship between filial responsibilities and adolescent wellbeing. These insights are valuable for family scholars and practitioners, informing the design of supportive services to enhance the psychological wellbeing of Chinese adolescents from economically disadvantaged single-mother families.

A Core Outcome Set for Intact Abdominal Aortic Aneurysm Repair.

OBJECTIVE: Technology and advances in clinical care have changed the management of abdominal aortic aneurysms (AAAs) but the clinical effectiveness of continuing advances needs to be assessed. To facilitate rapid synthesis of new evidence and improve stakeholder representation, including patients, the concept of core outcome sets (COS) has been developed. COS, reflecting the needs of all stakeholders, have been established across several surgical specialties. This study aimed to develop an international core outcome set for intact AAA repair. METHODS: Following COMET methodology, potential outcomes were identified from a systematic review of published outcomes and focus groups involving patients, carers, and nurses. A 38 question Delphi consensus survey in lay language was developed (with translation to local languages); this included 35 themes identified from the findings of the systematic review and three themes from the focus groups. All three of the themes identified by the focus groups (cognitive, physical, and social functioning) can be evaluated from quality of life instruments, with overall quality of life being identified from the systematic review. The survey was completed by patients, carers or family members, vascular nurses, vascular surgeons, trainees, interventional radiologists, anaesthetists, and industry partners from six European countries. After two rounds of the survey, the top outcomes were discussed at a face to face multistakeholder consensus meeting. RESULTS: The 38 item questionnaire was amended after piloting among all stakeholder groups. After the first round of the Delphi survey (98 respondents) 15 questions were eliminated, and 11 further questions were eliminated after round 2 (90 respondents). This left two outcome questions for discussion at the consensus meeting, where the top six outcomes were unanimously endorsed: death at 30 days (or in hospital if longer), secondary AAA rupture, overall quality of life and retention of cognitive functioning after recovery, five year survival, and continued sac growth. CONCLUSION: Six core outcomes are recommended for use as a minimum framework in all future studies and registries of intact open and endovascular AAA repair. Further work to select instruments for quality of life and to define instruments for cognitive functioning is needed.

Multireceptor phage cocktail against Salmonella enterica to circumvent phage resistance.

Non-Typhoidal Salmonella (NTS) is one of the most common food-borne pathogens worldwide, with poultry products being the major vehicle for pathogenesis in humans. The use of bacteriophage (phage) cocktails has recently emerged as a novel approach to enhancing food safety. Here, a multireceptor Salmonella phage cocktail of five phages was developed and characterized. The cocktail targets four receptors: O-antigen, BtuB, OmpC, and rough Salmonella strains. Structural analysis indicated that all five phages belong to unique families or subfamilies. Genome analysis of four of the phages showed they were devoid of known virulence or antimicrobial resistance factors, indicating enhanced safety. The phage cocktail broad antimicrobial spectrum against Salmonella, significantly inhibiting the growth of all 66 strains from 20 serovars tested in vitro. The average bacteriophage insensitive mutant (BIM) frequency against the cocktail was 6.22 × 10-6 in S. Enteritidis, significantly lower than that of each of the individual phages. The phage cocktail reduced the load of Salmonella in inoculated chicken skin by 3.5 log10 CFU/cm2 after 48 h at 25°C and 15°C, and 2.5 log10 CFU/cm2 at 4°C. A genome-wide transduction assay was used to investigate the transduction efficiency of the selected phage in the cocktail. Only one of the four phages tested could transduce the kanamycin resistance cassette at a low frequency comparable to that of phage P22. Overall, the results support the potential of cocktails of phage that each target different host receptors to achieve complementary infection and reduce the emergence of phage resistance during biocontrol applications.

A United States-based patient-reported adult polyglucosan body disease registry: initial results.

Background: Adult Polyglucosan Body Disease (APBD) is an ultra-rare, genetic neurodegenerative disorder caused by autosomal recessive mutations in the glycogen branching enzyme gene. Knowledge of the demographic and clinical characteristics of APBD patients and the natural history of the disease is lacking. We report here initial results from a patient-reported registry of APBD patients. Objectives: (1) Maximize the quality of the APBD Registry survey data; (2) provide an initial report on APBD disease progression and natural history using these data; and (3) specify next steps in the process for testing potential new therapies. Design: Data are from members of the APBD Research Foundation (New York), surveyed from 2014 by the Columbia APBD Patient/Family (CAP) Registry. Inclusion criteria are: disease onset at age 18+ and progressive clinical triad of peripheral neuropathy, spasticity, and neurogenic bladder. Methods: Genetic testing results were used when available. Respondents found to not have APBD in clinical records were excluded. All changes and exclusions were recorded in a database edit log. Results are reported in frequency tables, bar graphs, time plots, and heat maps. Results: The 96 respondents meeting inclusion criteria were predominantly (96.8%) White, highly educated (89.3% at least some college education), and mostly (85.1%) of Ashkenazi Jewish descent. 57.1% had at least one parent born in the United States, with at least one grandparent from Europe (excluding Russia; 75.4%), the United States (42.1%), or Russia (33.3%). 37.2% reported a family history of APBD, and 33.3% had an affected sibling. Median APBD onset age was 51 [Interquartile range (IQR) 11], and median age of diagnosis 57 (IQR 10.5). The 75 reported prior misdiagnoses were mainly peripheral neuropathy (43, 60.6%) and spinal stenosis (11, 15.1%). Conclusion: Although from a demographically constricted survey, the results provide basic clinical information for future studies to develop treatments for APBD.

A United States based patient-reported adult polyglucosan body disease registry: initial results Adult Polyglucosan Body Disease, or APBD, is an ultra-rare neurological disorder caused by mutations of the GBE1 gene. While potential therapies exist, to establish if they work we need a "natural history" study that shows the normal path of the disease. Our goal was to provide the first patient-reported natural history study of APBD. We analyzed survey data from 96 patients recruited by the APBD Research Foundation (New York), aged 18 or older, who self-reported having APBD. We maximized data quality by using results from genetic testing when these were available, and by excluding respondents if we could not review clinical records confirming they had APBD. More than 95% of our 96 patients were white. They were highly educated: 89% had at least some college education. Most (85%) were of Ashkenazi Jewish descent. More than half (57.1%) had a parent born in the United States. Many had at least one grandparent from Europe (excluding Russia) (75.4%), the United States (42.1%), or Russia (33.3%). More than a third (37%) reported a family history of APBD, and a third reported that they had a brother or a sister with a history of the disease. Their average age at APBD onset was 51, and their average age at APBD diagnosis was 57. Previous misdiagnoses were common: 75 were reported. Most were for peripheral neuropathy (60.6%) or spinal stenosis (16.7%). Although our data come from a survey of patients who are demographically similar, they provide a report on the characteristics of patients with APBD and basic information that is essential for studies to develop treatments for the disease.

Prevalence of orthostatic intolerance in long covid clinic patients and healthy volunteers: A multicenter study.

Orthostatic intolerance (OI), including postural orthostatic tachycardia syndrome (PoTS) and orthostatic hypotension (OH), are often reported in long covid, but published studies are small with inconsistent results. We sought to estimate the prevalence of objective OI in patients attending long covid clinics and healthy volunteers and associations with OI symptoms and comorbidities. Participants with a diagnosis of long covid were recruited from eight UK long covid clinics, and healthy volunteers from general population. All undertook standardized National Aeronautics and Space Administration Lean Test (NLT). Participants' history of typical OI symptoms (e.g., dizziness, palpitations) before and during the NLT were recorded. Two hundred seventy-seven long covid patients and 50 frequency-matched healthy volunteers were tested. Healthy volunteers had no history of OI symptoms or symptoms during NLT or PoTS, 10% had asymptomatic OH. One hundred thirty (47%) long covid patients had previous history of OI symptoms and 144 (52%) developed symptoms during the NLT. Forty-one (15%) had an abnormal NLT, 20 (7%) met criteria for PoTS, and 21 (8%) had OH. Of patients with an abnormal NLT, 45% had no prior symptoms of OI. Relaxing the diagnostic thresholds for PoTS from two consecutive abnormal readings to one abnormal reading during the NLT, resulted in 11% of long covid participants (an additional 4%) meeting criteria for PoTS, but not in healthy volunteers. More than half of long covid patients experienced OI symptoms during NLT and more than one in 10 patients met the criteria for either PoTS or OH, half of whom did not report previous typical OI symptoms. We therefore recommend all patients attending long covid clinics are offered an NLT and appropriate management commenced.

Sex differences in post-acute neurological sequelae of SARS-CoV-2 and symptom resolution in adults after coronavirus disease 2019 hospitalization: an international multi-centre prospective observational study.

Although it is known that coronavirus disease 2019 can present with a range of neurological manifestations and in-hospital complications, sparse data exist on whether these initial neurological symptoms of coronavirus disease 2019 are closely associated with post-acute neurological sequelae of SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2; PANSC) and whether female versus male sex impacts symptom resolution. In this international, multi-centre, prospective, observational study across 407 sites from 15 countries (30 January 2020 to 30 April 2022), we report the prevalence and risk factors of PANSC among hospitalized adults and investigate the differences between males and females on neurological symptom resolution over time. PANSC symptoms included altered consciousness/confusion, fatigue/malaise, anosmia, dysgeusia and muscle ache/joint pain, on which information was collected at index hospitalization and during follow-up assessments. The analysis considered a time to the resolution of individual and all neurological symptoms. The resulting times were modelled by Weibull regression, assuming mixed-case interval censoring, with sex and age included as covariates. The model results were summarized as cumulative probability functions and age-adjusted and sex-adjusted median times to resolution. We included 6862 hospitalized adults with coronavirus disease 2019, who had follow-up assessments. The median age of the participants was 57 years (39.2% females). Males and females had similar baseline characteristics, except that more males (versus females) were admitted to the intensive care unit (30.5 versus 20.3%) and received mechanical ventilation (17.2 versus 11.8%). Approximately 70% of patients had multiple neurological symptoms at the first follow-up (median = 102 days). Fatigue (49.9%) and myalgia/arthralgia (45.2%) were the most prevalent symptoms of PANSC at the initial follow-up. The reported prevalence in females was generally higher (versus males) for all symptoms. At 12 months, anosmia and dysgeusia were resolved in most patients, although fatigue, altered consciousness and myalgia remained unresolved in >10% of the cohort. Females had a longer time to the resolution (5.2 versus 3.4 months) of neurological symptoms at follow-up for those with more than one neurological symptom. In the multivariable analysis, males were associated with a shorter time to the resolution of symptoms (hazard ratio = 1.53; 95% confidence interval = 1.39-1.69). Intensive care unit admission was associated with a longer time to the resolution of symptoms (hazard ratio = 0.68; 95% confidence interval = 0.60-0.77). Post-discharge stroke was uncommon (0.3% in females and 0.5% in males). Despite the methodological challenges involved in the collection of survey data, this international multi-centre prospective cohort study demonstrated that PANSC following index hospitalization was high. Symptom prevalence was higher and took longer to resolve in females than in males. This supported the fact that while males were sicker during acute illness, females were disproportionately affected by PANSC.

Group peer mentoring is effective for different demographic groups of biomedical research faculty: A controlled trial.

INTRODUCTION: Improved mentoring of midcareer researchers in medical schools has been identified as an important potential avenue for addressing low vitality and high burnout rates in faculty, and the scarcity of both underrepresented minority (URM) faculty and women in biomedical research. To address the need for widescale effective mentoring, we sought to determine whether a group peer mentoring intervention (C-Change Mentoring and Leadership Institute) for early midcareer research faculty was effective for different demographic groups in a controlled trial. METHODS AND MATERIALS: Thirty-five diverse early midcareer faculty and 70 propensity-matched (PM) control subjects matched to intervention subjects on a) study inclusion criteria; b) gender, race, and ethnicity, degree, rank, years of experience, publications, grants; and c) pretest survey outcome variables, participated in the intervention. The C-Change Participant Survey assessed vitality, self-efficacy in career advancement, research success, mentoring others, valuing diversity, cognitive empathy, and anti-sexism/anti-racism skills at pretest and intervention completion. Analysis using multiple regression models included outcome pretest values and indicator variables for intervention, gender, URM status, and MD vs. PhD. Hypotheses regarding differential effectiveness of the intervention by demographic group were tested by including cross-product terms between the demographic indicator variables and the intervention indicator. Missing data were addressed using chained equations to create 100 data sets. RESULTS AND DISCUSSION: The intervention participants had significantly higher (favorable) scores than PM controls for: self-assessed change in vitality; self-efficacy for career advancement, research, and mentoring others; cognitive empathy; and anti-sexism/racism skills. The benefits of the intervention were nearly identical across: gender, URM vs non-URM faculty, and degree MD/PhD, except vitality significantly increased for non-URM subjects, and not for URM faculty. Self-assessed change in vitality increased for URM and non-URM. CONCLUSION: The intervention worked successfully for enhancing vitality, self-efficacy and cross-cultural engagement across different demographic groups of biomedical research faculty.

Editor's Choice -- European Society for Vascular Surgery (ESVS) 2024 Clinical Practice Guidelines on the Management of Abdominal Aorto-Iliac Artery Aneurysms.

OBJECTIVE: The European Society for Vascular Surgery (ESVS) has developed clinical practice guidelines for the care of patients with aneurysms of the abdominal aorta and iliac arteries in succession to the 2011 and 2019 versions, with the aim of assisting physicians and patients in selecting the best management strategy. METHODS: The guideline is based on scientific evidence completed with expert opinion on the matter. By summarising and evaluating the best available evidence, recommendations for the evaluation and treatment of patients have been formulated. The recommendations are graded according to a modified European Society of Cardiology grading system, where the strength (class) of each recommendation is graded from I to III and the letters A to C mark the level of evidence. RESULTS: A total of 160 recommendations have been issued on the following topics: Service standards, including surgical volume and training; Epidemiology, diagnosis, and screening; Management of patients with small abdominal aortic aneurysm (AAA), including surveillance, cardiovascular risk reduction, and indication for repair; Elective AAA repair, including operative risk assessment, open and endovascular repair, and early complications; Ruptured and symptomatic AAA, including peri-operative management, such as permissive hypotension and use of aortic occlusion balloon, open and endovascular repair, and early complications, such as abdominal compartment syndrome and colonic ischaemia; Long term outcome and follow up after AAA repair, including graft infection, endoleaks and follow up routines; Management of complex AAA, including open and endovascular repair; Management of iliac artery aneurysm, including indication for repair and open and endovascular repair; and Miscellaneous aortic problems, including mycotic, inflammatory, and saccular aortic aneurysm. In addition, Shared decision making is being addressed, with supporting information for patients, and Unresolved issues are discussed. CONCLUSION: The ESVS Clinical Practice Guidelines provide the most comprehensive, up to date, and unbiased advice to clinicians and patients on the management of abdominal aorto-iliac artery aneurysms.

Event rates and incidence of post-COVID-19 condition in hospitalised SARS-CoV-2 positive children and young people and controls across different pandemic waves: exposure-stratified prospective cohort study in Moscow (StopCOVID).

BACKGROUND: Long-term health outcomes in children and young people (CYP) after COVID-19 infection are not well understood and studies with control groups exposed to other infections are lacking. This study aimed to investigate the incidence of post-COVID-19 condition (PCC) and incomplete recovery in CYP after hospital discharge and compare outcomes between different SARS-CoV-2 variants and non-SARS-CoV-2 infections. METHODS: A prospective exposure-stratified cohort study of individuals under 18 years old in Moscow, Russia. Exposed cohorts were paediatric patients admitted with laboratory-confirmed COVID-19 infection between April 2 and December 11, 2020 (Wuhan variant cohort) and between January 12 and February 19, 2022 (Omicron variant cohort). CYP admitted with respiratory and intestinal infections, but negative lateral flow rapid diagnostic test and PCR-test results for SARS-CoV-2, between January 12 and February 19, 2022, served as unexposed reference cohort. Comparison between the 'exposed cohorts' and 'reference cohort' was conducted using 1:1 matching by age and sex. Follow-up data were collected via telephone interviews with parents, utilising the long COVID paediatric protocol and survey developed by the International Severe Acute Respiratory and Emerging Infection Consortium (ISARIC). The WHO case definition was used to categorise PCC. RESULTS: Of 2595 CYP with confirmed COVID-19, 1707 (65.7%) participated in follow-up interviews, with 1183/1707 (69%) included in the final 'matched' analysis. The median follow-up time post-discharge was 6.7 months. The incidence of PCC was significantly higher in the Wuhan variant cohort (89.7 cases per 1000 person-months, 95% CI 64.3-120.3) compared to post-infection sequalae in the reference cohort (12.2 cases per 1000 person-months, 95% CI 4.9-21.9), whereas the difference with the Omicron variant cohort and reference cohort was not significant. The Wuhan cohort had higher incidence rates of dermatological, fatigue, gastrointestinal, sensory, and sleep manifestations, as well as behavioural and emotional problems than the reference cohort. The only significant difference between Omicron variant cohort and reference cohort was decreased school attendance. When comparing the Wuhan and Omicron variant cohorts, higher incidence of PCC and event rates of fatigue, decreased physical activity, and deterioration of relationships was observed. The rate of incomplete recovery was also significantly higher in the Wuhan variant cohort than in both the reference and the Omicron variant cohorts. CONCLUSIONS: Wuhan variant exhibited a propensity for inducing a broad spectrum of physical symptoms and emotional behavioural changes, suggesting a pronounced impact on long-term health outcomes. Conversely, the Omicron variant resulted in fewer post-infection effects no different from common seasonal viral illnesses. This may mean that the Omicron variant and subsequent variants might not lead to the same level of long-term health consequences as earlier variants.

International Care programs for Pediatric Post-COVID Condition (Long COVID) and the way forward.

BACKGROUND: Pediatric Post-COVID-Condition (PPCC) clinics treat children despite limited scientific substantiation. By exploring real-life management of children diagnosed with PPCC, the International Post-COVID-Condition in Children Collaboration (IP4C) aimed to provide guidance for future PPCC care. METHODS: We performed a cross-sectional international, multicenter study on used PPCC definitions; the organization of PPCC care programs and patients characteristics. We compared aggregated data from PPCC cohorts and identified priorities to improve PPCC care. RESULTS: Ten PPCC care programs and six COVID-19 follow-up research cohorts participated. Aggregated data from 584 PPCC patients was analyzed. The most common symptoms included fatigue (71%), headache (55%), concentration difficulties (53%), and brain fog (48%). Severe limitations in daily life were reported in 31% of patients. Most PPCC care programs organized in-person visits with multidisciplinary teams. Diagnostic testing for respiratory and cardiac morbidity was most frequently performed and seldom abnormal. Treatment was often limited to physical therapy and psychological support. CONCLUSIONS: We found substantial heterogeneity in both the diagnostics and management of PPCC, possibly explained by scarce scientific evidence and lack of standardized care. We present a list of components which future guidelines should address, and outline priorities concerning PPCC care pathways, research and international collaboration. IMPACT: Pediatric Post-COVID Condition (PPCC) Care programs have been initiated in many countries. Children with PPCC in different countries are affected by similar symptoms, limiting many to participate in daily life. There is substantial heterogeneity in diagnostic testing. Access to specific diagnostic tests is required to identify some long-term COVID-19 sequelae. Treatments provided were limited to physical therapy and psychological support. This study emphasizes the need for evidence-based diagnostics and treatment of PPCC. The International Post-COVID Collaboration for Children (IP4C) provides guidance for guideline development and introduces a framework of priorities for PPCC care and research, to improve PPCC outcomes.

Incremental Contribution of the Minnesota Multiphasic Personality Inventory - 3 to Predicting One-Year Postoperative Spinal Cord Surgery/Spinal Cord Stimulation Outcomes.

Pre-surgical psychological assessments are becoming common in the United States and are recommended or required prior to surgical/spinal cord stimulator intervention for chronic back pain. Psychological testing is often recommended for these evaluations and the various versions of the Minnesota Multiphasic Personality Inventory (MMPI) have demonstrated utility for predicting outcomes in this setting. This investigation sought to extend that literature with the newest version of the MMPI, the MMPI-3. The sample comprised of 909 patients (50.5% men, 49.5% women) who consented to participating in an outcome study and took the MMPI-3 along with other self-report measures of pain, functional disability, and emotional functioning prior to surgery as part of their pre-surgical psychological assessment. Self-report measures of pain, functional disability, and emotional functioning were administered again one-year following the intervention. MMPI-3 scale scores accounted for up to 9% of additional variance in the outcomes after controlling for pre-surgical measures. Measures of emotional/internalizing dysfunction, somatic dysfunction, and, to a lesser extent, behavioral/externalizing dysfunction contributed the most to the prediction of poorer outcomes.

Assessment of Subclinical Atherosclerosis in Asymptomatic People In Vivo: Measurements Suitable for Biomarker and Mendelian Randomization Studies.

BACKGROUND: One strategy to reduce the burden of cardiovascular disease is the early detection and treatment of atherosclerosis. This has led to significant interest in studies of subclinical atherosclerosis, using different phenotypes, not all of which are accurate reflections of the presence of asymptomatic atherosclerotic plaques. The aim of part 2 of this series is to provide a review of the existing literature on purported measures of subclinical disease and recommendations concerning which tests may be appropriate in the prevention of incident cardiovascular disease. METHODS: We conducted a critical review of measurements used to infer the presence of subclinical atherosclerosis in the major conduit arteries and focused on the predictive value of these tests for future cardiovascular events, independent of conventional cardiovascular risk factors, in asymptomatic people. The emphasis was on studies with >10 000 person-years of follow-up, with meta-analysis of results reporting adjusted hazard ratios (HRs) with 95% CIs. The arterial territories were limited to carotid, coronary, aorta, and lower limb arteries. RESULTS: In the carotid arteries, the presence of plaque (8 studies) was independently associated with future stroke (pooled HR, 1.89 [1.04-3.44]) and cardiac events (7 studies), with a pooled HR, 1.77 (1.19-2.62). Increased coronary artery calcium (5 studies) was associated with the risk of coronary heart disease events, pooled HR, 1.54 (1.07-2.07) and increasing severity of calcification (by Agaston score) was associated with escalation of risk (13 studies). An ankle/brachial index (ABI) of <0.9, the pooled HR for cardiovascular death from 7 studies was 2.01 (1.43-2.81). There were insufficient studies of either, thoracic or aortic calcium, aortic diameter, or femoral plaque to synthesize the data based on consistent reporting of these measures. CONCLUSIONS: The presence of carotid plaque, coronary artery calcium, or abnormal ankle pressures seems to be a valid indicator of the presence of subclinical atherosclerosis and may be considered for use in biomarker, Mendelian randomization and similar studies.

Genomics for antimicrobial resistance surveillance to support infection prevention and control in health-care facilities.

Integration of genomic technologies into routine antimicrobial resistance (AMR) surveillance in health-care facilities has the potential to generate rapid, actionable information for patient management and inform infection prevention and control measures in near real time. However, substantial challenges limit the implementation of genomics for AMR surveillance in clinical settings. Through a workshop series and online consultation, international experts from across the AMR and pathogen genomics fields convened to review the evidence base underpinning the use of genomics for AMR surveillance in a range of settings. Here, we summarise the identified challenges and potential benefits of genomic AMR surveillance in health-care settings, and outline the recommendations of the working group to realise this potential. These recommendations include the definition of viable and cost-effective use cases for genomic AMR surveillance, strengthening training competencies (particularly in bioinformatics), and building capacity at local, national, and regional levels using hub and spoke models.
