The Role of Spinal Cord Compression in Predicting Intraoperative Neurophysiological Monitoring Events in Patients With Kyphotic Deformity: A Magnetic Resonance Imaging-Based Study.
OBJECTIVE
To establish a novel classification system for predicting the risk of intraoperative neurophysiological monitoring (IONM) events in surgically-treated patients with kyphotic deformity.
METHODS
Patients with kyphotic deformity who underwent surgical correction of cervicothoracic, thoracic, or thoracolumbar kyphosis in our center from July 2005 to December 2020 were recruited. We proposed a classification system to describe the morphology of the spinal cord on T2-weighted sagittal magnetic resonance imaging: type A, circular/symmetric cord with visible cerebrospinal fluid (CSF) between the cord and vertebral body; type B, circular/oval/symmetric cord with no visible CSF between the cord and vertebral body; type C, spinal cord that is fattened/deformed by the vertebral body, with no visible CSF between the cord and vertebral body. Furthermore, based on type C, the spinal cord compression ratio (CR) < 50% was defined as the subtype C-, while the spinal cord CR ≥ 50% was defined as the subtype C+. IONM event was documented, and a comparative analysis was made to evaluate the prevalence of IONM events among patients with diverse spinal cord types.
RESULTS
A total of 294 patients were reviewed, including 73 in type A; 153 in type B; 53 in subtype C- and 15 in subtype C+. Lower extremity transcranial motor-evoked potentials and/or somatosensory evoked potentials were lost intraoperatively in 41 cases (13.9%), among which 4 patients with type C showed no return of spinal cord monitoring data. The 14 subtype C+ patients (93.3%) had IONM events. Univariate logistic regression analysis showed that patients with a type C spinal cord (subtype C-: odds ratio [OR], 10.390; 95% confidence interval [CI], 2.215-48.735; p = 0.003; subtype C+, OR, 497.000; 95% CI, 42.126- 5,863.611; p < 0.001) are at significantly higher risk of a positive IONM event during deformity correction compared to those with a type A. In further multiple logistic regression analysis, the spinal cord classification (OR, 5.371; 95% CI, 2.966-9.727; p < 0.001) was confirmed as an independent risk factor for IONM events.
CONCLUSION
We presented a new spinal cord classification system based on the relative position of the spinal cord and vertebrae to predict the risk of IONM events in patients with kyphotic deformity. In patients with type C spinal cord, especially those in C+ cases, it is essential to be aware of potential IONM events, and adopt standard operating procedures to facilitate neurological recovery.

Saudi Medical Journal Jul 2024To estimate the incidence of post tonsillectomy bleeding and to identify its predisposing factors among the pediatric population.
OBJECTIVES
To estimate the incidence of post tonsillectomy bleeding and to identify its predisposing factors among the pediatric population.
METHODS
A retrospective cohort study included 1280 pediatric patients (18 years or younger) who underwent tonsillectomy at King Abdullah Specialized Children Hospital, Riyadh, Saudi Arabia between 2019 and 2020. The study sample was divided into 2 groups based on the development of postoperative bleeding and were compared using Chi-square test and independent t-test. Significant variables (-value ≤0.05) were included in the logistic regression model to determine the predictors of bleeding following tonsillectomy.
RESULTS
The bleeding rate following tonsillectomy was 3.4% in 43 (95% confidence interval [CI] 2.4-4.5) patients. In the multivariable logistic regression model, the significant predictors of post tonsillectomy bleeding were age ≥12 years (odds ratio [OR]: 2.685, =0.027), decreased postoperative oral intake (OR: 4.244, =0.042), and single use of postoperative analgesia (OR: 53.124, <0.001). Out of the 43 patients, 39 (90.7%) patients experienced secondary bleeding, and more than half of the patients who developed bleeding required surgical intervention 27 (62.8%).
CONCLUSION
Tonsillectomy is a safe and common surgical procedure but carries risks for postoperative bleeding. Age ≥12 years, poor postoperative oral intake, and the use of a single postoperative analgesic increase the risk of bleeding. We encourage healthcare providers to ascertain early resumption of oral intake and ensure effective pain management. We recommend a dual alternating analgesic regimen with weight-based dosing for optimal pain control. Furthermore, educating caregivers about the importance of adequate oral intake following tonsillectomy may improve patient outcomes.

Previous studies reporting the association between gut microbiota dysbiosis and maternal obesity were mostly confined at the phylum level or at postpartum period. This study aimed to investigate the dynamic changes in gut microbial communities associated with maternal obesity at different time points of pregnancy. We performed 16S rRNA gene V3-V4 amplicon sequencing on stool samples from 110 women in all three trimesters and 1-month postpartum. Maternal gut microbial communities associated with maternal pre-pregnancy body mass index (BMI) and gestational weight gain (GWG) were explored. The influence of maternal obesity on gut microbiota trajectories was determined based on longitudinal shifts in community clusters across the trimesters. The richness index of alpha diversity decreased with the progression of pregnancy, particularly in women with excessive GWG. The evenness index in 2nd trimester was found inversely associated with GWG. Various taxonomic differences in 1st trimester were associated with excessive GWG, whereas limited taxonomic differences in 2nd and 3rd trimesters were associated with pre-pregnancy BMI or GWG. Meanwhile, the gut microbiota trajectory with especially depleted genus Faecalibacterium in 1st trimester was associated with excessive GWG (adjusted odds ratio 5.7, 95% confidence interval 1.2-28.1). Moreover, the longitudinal abundances of genus Lachnospiraceae ND3007 group across gestations were depleted in women with overweight/obese pre-pregnancy BMI, while genus Bifidobacterium enriched in women with excessive GWG. Our study shows that dysbiosis of the gut microbiota in early pregnancy may have a significant impact on excess GWG. The abundance of the genus Faecalibacterium in 1st trimester may be a potential risk factor. Clinical trial number: NCT03785093 (https://classic.clinicaltrials.gov/ct2/show/NCT03785093).

INTRODUCTION
This study endeavors to decipher the association between Activin A and PRISm, thereby addressing the potential of Activin A as a serum biomarker for early detection and long-term clinical outcome prediction of PRISm and subsequent all-cause mortality.
METHODS
The study sample comprised middle-aged and older adults from the I-Lan Longitudinal Aging Study. Pulmonary function including forced vital capacity (FVC) and forced expiratory volume in one second (FEV) were measured. Demographic data and laboratory data (including serum Activin A levels) were also collected. Multivariate logistic regression and Cox proportional hazards models were used to identify independent predictors of PRISm and all-cause mortality, respectively.
RESULTS
Among 711 eligible participants, 34 % had PRISm. The risk of PRISm elevated with Activin A levels in group quartiles (adjusted odds ratio (aOR), Q2: 1.606 [95 % CI 0.972-2.652], p = 0.064, Q3: 2.666 [1.635-4.348], p < 0.001, Q4: 3.225 [1.965-5.293], p < 0.001). On the other hand, lower hemoglobin (aOR: 1.122, p = 0.041) and higher blood urea nitrogen (BUN) levels (aOR: 1.033, p = 0.048) were associated with increased risk of PRISm. In addition, the PRISm group had a higher all-cause mortality rate (non-PRISm 4.5% vs. PRISm 8.3 %, p = 0.038). Multivariate Cox models also identify a higher level of Activin A as a risk factor of all-cause mortality (aHR: 1.001 [1.000-1.003], p = 0.042).
CONCLUSIONS
Higher Activin A quartiles were linked to increased risk of PRISm, along with lower hemoglobin and higher BUN levels. Additonally, elevated Activin A was a significant risk factor of all-cause mortality.

Review
BACKGROUND
Subarachnoid hemorrhage (SAH) is associated with high rates of mortality and morbidity, particularly among elderly patients. The presence of frailty may impact survival rates in patients with SAH. In this study, we aim to investigate the impact of frailty on the clinical outcomes in SAH patients.
METHODS
We conducted a systematic review and meta-analysis following the Preferred Reporting Items for Systematic reviews and Meta-Analyses (PRISMA) guidelines. Relevant papers through December 2023 were retrieved from PubMed, Scopus, Web of science, and Embase.
RESULTS
A total of 5 studies met inclusion/exclusion criteria with an aggregate 39,221 non-frail patients (mean age 52.4 ± 5.2 yr; 62.1 % Female), and 79,416 frail patients (mean age 61.1 ± 5.4 yr; 69.0 % Female). Frailty was significantly associated with higher mortality ratio (Odds ratio (OR)= 2.09; CI [1.04: 4.20], p= 0.04), and increased length of hospital stay (OR= 1.40; CI [1.07: 1.83], p= 0.015). Additionally, frailty was associated with higher odds of external ventricular drain insertion, the need of tracheostomy/endoscopic gastrostomy, increased risk of deep vein thrombosis, and postoperative neurological complications.
CONCLUSION
Frailty is associated with worse clinical outcomes and higher mortality rates in SAH patients. Our findings highlight that frailty, when considered alongside other established prognostic factors, serves as crucial predictor for peri-operative complications and overall hospital course in SAH patients.

BACKGROUND
Exposure to opioids after surgery is the initial contact for some people who develop chronic opioid use disorder. Hence, effective postoperative pain management, with less reliance on opioids, is critical. The Perioperative Opioid Quality Improvement (POQI) program developed (1) a digital health platform leveraging patient-survey-reported risk factors and (2) a postsurgical pain risk stratification algorithm to personalize perioperative care by integrating several commercially available digital health solutions into a combined platform. Development was reduced in scope by the COVID-19 pandemic.
OBJECTIVE
This pilot study aims to assess the screening performance of the risk algorithm, quantify the use of the POQI platform, and evaluate clinicians' and patients' perceptions of its utility and benefit.
METHODS
A POQI platform prototype was implemented in a quality improvement initiative at a Canadian tertiary care center and evaluated from January to September 2022. After surgical booking, a preliminary risk stratification algorithm was applied to health history questionnaire responses. The estimated risk guided the patient assignment to a care pathway based on low or high risk for persistent pain and opioid use. Demographic, procedural, and medication administration data were extracted retrospectively from the electronic medical record. Postoperative inpatient opioid use of >90 morphine milligram equivalents per day was the outcome used to assess algorithm performance. Data were summarized and compared between the low- and high-risk groups. POQI use was assessed by completed surveys on postoperative days 7, 14, 30, 60, 90, and 120. Semistructured patient and clinician interviews provided qualitative feedback on the platform.
RESULTS
Overall, 276 eligible patients were admitted for colorectal procedures. The risk algorithm stratified 203 (73.6%) as the low-risk group and 73 (26.4%) as the high-risk group. Among the 214 (77.5%) patients with available data, high-risk patients were younger than low-risk patients (age: median 53, IQR 40-65 years, vs median 59, IQR 49-69 years, median difference five years, 95% CI 1-9; P=.02) and were more often female patients (45/73, 62% vs 80/203, 39.4%; odds ratio 2.5, 95% CI 1.4-4.5; P=.002). The risk stratification was reasonably specific (true negative rate=144/200, 72%) but not sensitive (true positive rate=10/31, 32%). Only 39.7% (85/214) patients completed any postoperative quality of recovery questionnaires (only 14, 6.5% patients beyond 60 days after surgery), and 22.9% (49/214) completed a postdischarge medication survey. Interviewed participants welcomed the initiative but noted usability issues and poor platform education.
CONCLUSIONS
An initial POQI platform prototype was deployed operationally; the risk algorithm had reasonable specificity but poor sensitivity. There was a significant loss to follow-up in postdischarge survey completion. Clinicians and patients appreciated the potential impact of preemptively addressing opioid exposure but expressed shortcomings in the platform's design and implementation. Iterative platform redesign with additional features and reevaluation are required before broader implementation.

Physical Medicine and Rehabilitation (PM&R) has rapidly been garnering interest as healthcare increases the emphasis on rehabilitation and management for acute and chronic diseases. This study analyzes recent geographical trends of PM&R residents via PM&R residents from 2019 to 2023 which were identified from publicly available data. The relative distribution from medical school to residency, medical school to preliminary program, and preliminary program to residency were analyzed. These locations were categorized as within 100 miles, same state, same region, or different region. Odds ratio (OR) were calculated for the aforementioned relative locations with respect to the presence of a home residency program. A total of 1836 residents were included. The majority of residents (51%) stayed within the same region as their medical school. Residents from medical schools with a home program were more likely to stay within 100 miles (OR: 3.64), the same state (OR: 3.19), and same region (OR: 2.56). Overall, PM&R residents are likely to stay within the same region as their medical school and preliminary year. Additionally, the presence of a home program significantly increases the odds of matching within 100 miles, same state, and same region.

Clinical characteristics and factors associated with long COVID among post-acute COVID-19 clinic patients in Zambia, August 2020 to January 2023: A cross-sectional and longitudinal study design.
INTRODUCTION
A number of seroprevalence studies in Zambia document the extent of spread of acute SARS-CoV-2 infection, yet knowledge gaps still exist on symptoms and conditions that continue or develop after acute COVID-19 (long COVID). This is an important gap given the estimated prevalence of long COVID in other African countries. We assessed factors associated with long COVID at the initial visit to a post-acute COVID-19 (PAC-19) clinic and longitudinally among a cohort of patients with ≥2 review visits.
METHODS
We implemented a cross-sectional and longitudinal analysis of PAC-19 clinic patients from Aug-2020 to Jan-2023. The study outcome was long COVID; defined as the presence of new, relapsing, or persistent COVID-19 symptoms that interfere with the ability to function at home or work. Explanatory variables were demographic and clinical characteristics of patients which included sex, age group, presence of new onset medical conditions, presence of pre-existing comorbidities, vaccination status and acute COVID-19 episode details. We fitted logistic and mixed effects regression models to assess for associated factors and considered statistical significance at p<0.05.
RESULTS
Out of a total 1,359 PAC-19 clinic patients in the cross-sectional analysis, 548 (40.3%) patients with ≥2 PAC-19 clinic visits were in the longitudinal analysis. Patients' median age was 53 (interquartile range [IQR]: 41-63) years, 919 (67.6%) were hospitalized for acute COVID-19, and of whom 686 (74.6%) had severe acute COVID-19. Overall, 377 (27.7%) PAC-19 clinic patients had long COVID. Patients with hospital length of stay ≥15 days (adjusted odds ratio [aOR]: 5.37; 95% confidence interval [95% CI]: 2.99-10.0), severe acute COVID-19 (aOR: 3.22; 95% CI: 1.68-6.73), and comorbidities (aOR:1.50; 95% CI: 1.02-2.21) had significantly higher chance of long COVID. Longitudinally, long COVID prevalence significantly (p<0.001) declined from 75.4% at the initial PAC-19 visit to 26.0% by the final visit. The median follow-up time was 7 (IQR: 4-12) weeks.
CONCLUSION
Factors associated with long COVID in Zambia were consistent both cross-sectionally at the initial visit to PAC-19 clinics and longitudinally across subsequent review visits. This highlights the importance of ongoing monitoring and tailored interventions for patients with comorbidities and severe COVID-19 to mitigate the long-term impacts of COVID-19.

IMPORTANCE
Guideline-recommended medications for overactive bladder and urge urinary incontinence (OAB/UUI) are effective but have high costs and side effects. Little is known about patient concerns regarding these medications when prescribed by their primary care providers (PCPs).
OBJECTIVE
The aim of the study was to describe PCP-patient interactions when prescribing medications for OAB/UUI, specifically clinical concerns, cost and authorization issues, and mode of communication for these interactions.
STUDY DESIGN
Using electronic health records, we identified a retrospective cohort of women aged 18-89 years who were prescribed a medication for OAB/UUI during a primary care office visit from 2017 to 2018. We examined the electronic health record from initial prescription through 15 subsequent months for documentation of prior authorization requests and patient concerns about cost, side effects, or ineffectiveness. The association of patient demographics, comorbidity, and medication class with these concerns was examined with logistic regression models.
RESULTS
Overall, 46.2% of patients (n = 123) had 1 or more OAB/UUI medication concerns, and 52 reported outside an office visit. Only higher comorbidity was associated with reduced concern of any type. Although the overall percent age of patients reporting concerns was similar by medication type, the patterns of concern type varied. Compared with those taking short-acting antimuscarinics, patients taking long-acting antimuscarinics other than oxybutynin were less likely to have side effect concerns (adjusted odds ratio 0.35, 95% CI 0.16-0.78) and more likely to have cost concerns (adjusted odds ratio 5.10, 95% CI 1.53-17.03).
CONCLUSIONS
Patient concerns regarding OAB/UUI medications were common in primary care practices and frequently reported outside of office visits. However, the patterns of concerns (cost vs side effects) varied between medication classes.

The prevention paradox describes circumstances in which the majority of cases with a suicide attempt come from a population of low or moderate risk, and only a few from a 'high-risk' group. The assumption is that a low base rate in combination with multiple causes makes it impossible to identify a high-risk group with all suicide attempts. The best way to study events such as first-time suicide attempts and their causes is to collect event history data. Administrative registers were used to identify a group at higher risk of suicidal behaviour within a population of six national birth cohorts (N = 300,000) born between 1980 and 1985 and followed from age 15 to 29 years. Estimation of risk parameters is based on the discrete-time logistic odds-ratio model. Lifetime prevalence was 4.5% for first-time suicide attempts. Family background and family child-rearing factors were predicative of later first-time suicide attempts. A young person's diagnosis with psychiatric or neurodevelopmental disorders (ADHD, anxiety, depression, PTSD), and being a victim of violence or sex offences contributed to the explanatory model. Contrary to the prevention paradox, results suggest that it is possible to identify a discrete high-risk group (<12%) among the population from whom two thirds of all first-time suicide attempts occur, but one third of observed suicide attempts derived from low- to moderate-risk groups. Findings confirm the need for a combined strategy of universal, targeted and indicated prevention approaches in policy development and in strategic and practice responses, and some promising prevention strategies are presented.
