The optimal patient panel size (PPS) in primary care and the factors determining it remain unclear. We conducted a meta-narrative review of the literature to evaluate factors influencing PPS and assess its association with patient outcomes. A comprehensive search of electronic databases was performed from inception through December 2023, focusing on original studies reporting factors used to determine PPS and related outcomes (eg, clinical outcomes, process measures, and resource utilization). A total of 48 studies were included, identifying 7 key factors influencing PPS. Smaller panels were associated with improved patient satisfaction, continuity of care, and health promotion, while clinical outcomes, utilization, and costs showed minimal impact by PPS. Panel size was primarily associated with patient age, sex, comorbidities, and practice type and structure. Community-based centers typically managed smaller panels, often staffed by female clinicians and serving socioeconomically disadvantaged populations with greater health needs than hospital-based practices. Female clinicians were also independently associated with managing smaller panels, higher quality care indicators, fewer emergency department visits, and improved patient satisfaction. Determining the ideal PPS is a multifaceted process influenced by practice setting, patient demographics, and clinician characteristics. While practice-related factors showed limited association with PPS, patient-reported outcomes were more closely linked to it. Primary care practices should tailor panel sizes to their patient populations, emphasizing a patient-centered approach and ensuring adequate infrastructure support to optimize care delivery.

BACKGROUND: Complex regional pain syndrome (CRPS) is a debilitating and painful condition accompanied by sensory, autonomic, trophic, and/or motor abnormalities. Although CRPS is rare in the general population, the prevalence among individuals at higher risk, particularly posttraumatic and postsurgical patients, remains unknown. This study aims to provide a benchmark that quantifies CRPS prevalence in high-risk groups, and offers insights on potential predictors of developing CRPS. METHODS: We conducted a systematic review and meta-analysis to identify studies reporting prevalence of CRPS after an inciting event (eg, fracture, surgery), specifically 12-month and 24-month prevalence (primary outcomes), as well as 3-month and 6-month prevalence (secondary outcomes). Estimates from individual studies were transformed using double-arcsine transformation, and the resulting estimates with 95% confidence interval (CI) were pooled in a meta-analysis using a random-effects model. RESULTS: We included 214 articles with data from 2491,378 participants worldwide (35 countries), of which 16,873 had CRPS. The pooled 12-month and 24-month global prevalence was 3.04% (95% CI, 2.64–3.48) and 6.46% (95% CI, 5.46–7.53), respectively. Subgroup analysis and meta-regression were performed to understand the impact of population-dependent (mechanism of injury, type of CRPS), contextual-dependent (socioeconomic status), and methodological-dependent (study design, publication year) factors. The 12-month prevalence was higher in countries with a high human development index (HDI) compared to those with a medium or very high HDI, was higher in participants with a traumatic inciting injury only versus those with surgical injury only or traumatic/surgical injury, and was higher in prospective versus retrospective studies. Meta-regression analysis showed that publication year was a significant moderator, with more recent articles reporting lower 12-month prevalence. CONCLUSIONS: This study provides a benchmark of the global prevalence of CRPS, which anesthesiologists and pain specialists can use to prioritize early diagnosis and identify those at the highest risk for CRPS.

Introduction Although the prevalence of chemotherapy-induced peripheral neuropathy (CIPN) has been reported, the proportion of patients with CIPN who report chronic moderate-to-severe neuropathy or chronic painful neuropathy remains poorly understood, despite its significant impact on patients’ quality of life and treatment outcomes. Methods A systematic review and meta-analysis were conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The primary outcome was the pooled prevalence of chronic (≥3 months) moderate-to-severe CIPN or painful CIPN among patients diagnosed with CIPN. Estimates from each study were transformed using a double-arcsine transformation and pooled in a meta-analysis using an inverse variance heterogeneity model. Subgroup analysis was conducted based on geographical region, sex, chemotherapy regimen, primary cancer type, and funding source; metaregression analysis was conducted based on study design, human development index (HDI), and publication year. Results 76 studies from 29 countries, encompassing 13 635 patients with CIPN, were included. Among patients diagnosed with CIPN, the pooled prevalence of those reporting chronic moderate-to-severe CIPN or painful CIPN was estimated at 47.76% (95% CI 37.50 to 58.08; 95% prediction interval 24.68–71.84). Substantial heterogeneity was observed across studies ( I² =97.45%; 95% CI for I 2 97.15 to 97.72). Subgroup analysis revealed that patients treated with platinum-based agents and taxanes had the highest prevalence of chronic moderate-to-severe CIPN or painful CIPN (44.47% and 55.68%, respectively), and among primary cancers, those with breast cancer, multiple myeloma, and lung cancer reported the highest prevalence of chronic moderate-to-severe CIPN or painful CIPN (61.31%, 53.55%, and 50.85%, respectively). Study design, HDI, and publication year were non-significant moderators of prevalence estimates. Based on our Grading of Recommendations, Assessment, Development, and Evaluation assessment, the certainty of evidence was considered “very low.” Sensitivity analysis restricted to studies explicitly measuring painful CIPN (40.78%; 95% CI 29.08 to 52.74) or moderate-to-severe CIPN (49.04%; 95% CI 37.16 to 60.95) yielded similar prevalence estimates. Conclusion This study provides the first comprehensive global estimate of the prevalence of chronic moderate-to-severe CIPN or painful CIPN, highlighting its significant burden on patients worldwide. The variation in prevalence across geographical regions, chemotherapy regimens, and primary cancers underscores the need for tailored management strategies and further research to address potential disparities.

Abstract Southeast Minnesota is home to a significant population of Anuak individuals who seek care within the Mayo Clinic Health Systems. The city of Austin, MN is home to a population numbering around 450 Anuak individuals who are seen at the Mayo Clinic Austin location as well as the Rochester main campus of Mayo Clinic. In total, more than 3000 Anuak individuals live in Minnesota in what is considered to be the largest Anuak population outside of East Africa. For pediatric patients with SCD, 15 of 20 (75%) are Anuak. The majority of these patients have severe SCD with chronic anemia, frequent pain crises, cardiac ventricular enlargement, acute chest pain, and multiple hospital admissions. The objective of this review is to understand what is known about SCD, the severity of phenotype, and outcomes in the published literature regarding this special population. A scoping review was conducted using primarily OVID databases. Only 2 studies met established criteria. Unfortunately, both sources of literature were dated and not consistent with current trends. Despite communicating with colleagues in Ethiopia, there does not exist accurate or robust data about the incidence or prevalence of SCD among the Anuak people. The local Anuak diaspora in Southeast Minnesota likely represents the best current data and representation in this patient population. There is a need for further research regarding SCD outcomes in this special population.

AbstractHistorically, cementless patellar implants were fraught with issues of fixation and polyethylene wear. However, contemporary cementless patellar implants incorporate modern technologies for implant design and offer the potential for improved biological fixation and longevity. As such, an evaluation of the performance of modern cementless patellae is needed. The purpose of this study was to perform a systematic review and meta-analysis of contemporary cementless patellar implants used during primary total knee arthroplasty (TKA), with a particular focus on aseptic loosening of the patellar component. A systematic review of the literature was performed from January 2000 to February 22, 2024. We included all peer-reviewed studies that reported the number of revisions in patients who had cementless patellae placed in 2000 or later during primary TKA. Reviews and case reports were excluded. Out of 639 studies, 13 were included with a total of 3,005 cementless patellae analyzed. The mean patient age was 64 years and the mean body mass index (BMI) was 31 kg/m2. Meta-analyses were performed to calculate the pooled revision rate per person-year of revision for aseptic loosening of the patellar component and revision for any patellar failure. Upon analysis of 13 studies involving a total of 3,005 cementless patellae, the revision rate for aseptic loosening of the patella was 0.2 per 1,000 person-years and the revision rate for any patellar failure was 1 per 1,000 person-years. Contemporary cementless patellar implants showed an overall revision rate of 1 per 1,000 person-years, demonstrating excellent longevity. The high survivorship, together with a low rate of loosening, show the utility and effectiveness of these implants. Given the nature of biologic fixation, these results are promising for long-term implant stability but additional follow-up is warranted.

Abstract Objective To assess the association of aPL and diffuse alveolar haemorrhage (DAH) in patients with SLE by performing a systematic review and meta-analysis. Methods Multiple databases were systematically searched from inception to February 2024. Studies were eligible if they included patients with SLE (population), reported aPL status (exposure), and DAH (outcome). We pooled the estimates as odds ratio (OR) using fixed-effect models. We examined the association between aPL and DAH, as well as associations based on aPL subtypes or concomitant APS. Results Out of 454 screened studies, nine were included in meta-analysis, encompassing 7746 patients with SLE, of whom 2016 (26.0%) were aPL-positive and 163 (2.1%) had DAH. Patients with SLE and positive aPL (any) were more likely to develop DAH than aPL-negative patients (OR = 1.76, 95% CI 1.24–2.49; I2 = 0%). Patients with SLE and positive LA (OR = 1.76, 95% CI 1.06–2.93, I2 = 35%) or positive anticardiolipin IgG (OR = 1.62, 95% CI 1.13–2.34, I2 = 0%) had a higher likelihood of developing DAH compared with patients that were negative for these aPL. An APS diagnosis was associated with a 2.5-fold increased likelihood of DAH compared with subjects without APS (OR = 2.46, 95% CI 1.23–4.92, I2 = 0%). Positivity of anti-β2 glycoprotein I IgG was not significantly associated with DAH among patients with SLE (OR = 0.78, 95% CI 0.45–1.36, I2 = 0%). Conclusion In patients with SLE, aPL positivity increases the risk of DAH compared with aPL-negative patients, particularly in those positive for LA and anticardiolipin IgG.

Background and Aims: This systematic review and meta-analysis aims to compare the performance of UroVysion® FISH based on the different definitions of a positive result used in published literature with the goal of determining the optimal FISH definition for detecting pancreaticobiliary malignancy. Methods: A systematic literature search identified studies from database inception to Sept 2024 that evaluated the diagnostic performance of FISH in determining malignancy among patients with biliary strictures. All thresholds for positive FISH, as defined by the individual study, were included in this review. Subgroup analysis was performed based on the definitions of positive FISH as follows: (1) polysomy only; (2) polysomy, tetrasomy, or trisomy; and (3) polysomy or 9p deletion. Results: Eighteen studies comprising 2516 FISH specimens were analyzed, including 1133 (45.0%) with malignancy. Using a threshold for positivity as defined in individual studies, the overall sensitivity of FISH was 57.6% (95% confidence interval [CI], 49.4–65.4%), and the overall specificity was 87.8% (95% CI, 79.2–93.2%). Subgroup analysis showed that polysomy as the threshold for positive FISH yielded a sensitivity of 49.4% (95% CI, 43.2–55.5%), with an increased specificity of 96.2% (95% CI, 92.7–98.1%), while polysomy + tetrasomy/trisomy as positive FISH resulted in an increased sensitivity of 64.3% (95% CI 55.4–72.2%) but a decreased specificity of 78.9% (95% CI 64.4–88.5%). The addition of 9p deletion to polysomy as the criteria for a positive test resulted in a non-significant increase in sensitivity (54.7% (95% CI 42.4–66.5%) while maintaining specificity (95.1% (95% CI 84.0–98.6%). Conclusions: Based on these findings, polysomy only or polysomy/9p deletion should be considered as the criterion for defining a positive FISH test to improve diagnostic sensitivity while maintaining high specificity.

Introduction Despite the increasingly evidenced positive impacts of green space on human physical and mental health, green spaces remain inequitably distributed across different socioeconomic groups. Urban planning and design should prioritise the development and maintenance of urban green spaces, especially for vulnerable and marginalised populations while thinking about protecting them from the effects of green gentrification. This scoping review will explore how the concepts of equity, diversity and inclusion are integrated into the design, the planning and policy development of urban green spaces. Also, we will explore what are the efforts made to incorporate equity, diversity, and inclusion concepts into the planning, design and policy development of urban green spaces to make them equitable for vulnerable and marginalised populations. Methods and analysis This protocol is based on the methodology developed by Arksey and O’Malley and improved by Levac et al . The search will be done in conjunction with a professional librarian, to include studies in all languages. The review will include multidisciplinary databases: Ovid MEDLINE, Ovid EMBASE, CINAHL, Web of Science and GeoBase. The search will be done from each database’s inception to February 2024. We will present our results narratively and will conduct a thematic analysis using the urban green equity framework. This framework will guide our understanding of the interplay between the spatial distribution of urban green spaces and the recognition of diverse voices in urban greening decision-making. Ethics and dissemination This scoping review will not require ethical approval since it will be collected from publicly available documents. The results of this scoping review will be presented as a scientific article, social media and public health or environmental conferences organised by environmental organisations or academic institutions.

AbstractBackgroundCytomegalovirus (CMV) is a significant cause of morbidity and mortality in solid organ transplant recipients (SOTRs). Secondary prophylaxis (SP) is not routinely recommended by guidelines on the management of CMV in SOTR but may be considered in certain higher‐risk situations.MethodsA comprehensive search of English language publications up to September 2023 was performed. The primary outcome was CMV relapse, defined as the recurrence of DNAemia or disease. Secondary outcomes included graft loss, mortality, and hematological toxicity. Meta‐analysis used the random‐effects model. The study protocol is registered in PROSPERO (no. CRD42022357028).ResultsSix retrospective comparative studies were included. A total of 520/727 (72%) of SOTR received SP with valganciclovir. The meta‐analysis did not demonstrate a significant difference in CMV relapse (odds ratio [OR] 1.15, 95% confidence interval [CI] 0.79–2.63). Heterogeneity between the studies was low (I2 = 0%, p = 0.57). SP was significantly associated with a reduction in mortality (OR 0.2, 95% CI 0.07–0.54) but not graft loss (OR 0.67, 0.17–2.63). There was no significant difference in CMV relapse among kidney‐specific SOTR (OR 1.38, 95% CI 0.65–2.96).ConclusionEvidence from six nonrandomized studies is limited and cannot support a recommendation for or against routine SP in SOTR treated for CMV infection. Awaiting prospective‐controlled trials, the decision about SP should depend on individualized risk‐profile assessments by experienced clinicians. image

Background Randomized clinical trials (RCTs) are considered the gold standard for evaluating the efficacy of healthcare interventions. However, conflicts of interest (COIs) can compromise the scientific integrity in these trials. This study characterized COIs in RCTs on spinal cord stimulation for chronic pain, focusing on the prevalence, disclosure, and monetary value of COIs. Methods This cross-sectional study analyzed RCTs published from January 1, 2013 to July 27, 2023. Primary outcomes included the presence, disclosure, and monetary value of COIs, while secondary outcomes assessed the presence of direct/indirect COIs, sponsor access to data, and associations between COIs and select variables, including journal impact factor, publication year, and study outcomes. Results Of 38 RCTs, 30 (78.9%) reported COIs. On average, 35.6% of authors per RCT had at least one COI, with a mean of 0.7 COIs per author. The mean annual monetary value of COIs was US$41,157.83 per author per RCT. 29 RCTs (76.3%) had undisclosed COIs, with an average of 24.2% of authors per RCT having undisclosed COIs. Sponsor access to data was reported in 67.6% of RCTs. No associations were observed between the mean percentage of authors with COIs and the monetary value of COIs and select dependent variables (impact factor, publication year, and study outcomes). Conclusions A substantial majority of RCTs reported COIs with many authors having undisclosed conflicts, highlighting the need for stringent COI disclosure guidelines to maintain research integrity. Expanding COI registry systems globally and increasing non-industry funding are crucial steps toward enhancing transparency and reducing biases in medical research.
