Multiple sclerosis (MS) and myalgic encephalomyelitis (ME)/chronic fatigue syndrome (CFS) share the symptom of fatigue, and might even coexist together. Specifically focusing on genetics, pathophysiology, and neuroimaging data, the authors discuss an overview of the parallels, correlation, and differences in fatigue between MS and ME/CFS along with ME/CFS presence in MS. Studies have revealed that the prefrontal cortex and basal ganglia regions, which are involved in fatigue regulation, have similar neuroimaging findings in the brains of people with both MS and ME/CFS. Additionally, in both conditions, genetic factors have been implicated, with particular genes known to enhance susceptibility to MS and CFS. Management approaches for fatigue in MS and ME/CFS differ based on the underlying factors contributing to fatigue. The authors also focus on the recent updates and the relationship between MS and sleep disorders, including restless legs syndrome, focusing on pathophysiology and therapeutic approaches. Latest therapeutic approaches like supervised physical activity and moderate-intensity exercises have shown better outcomes.

Background: Abortion is a spontaneous loss of pregnancy before 20 weeks. Approximately 42 million pregnancies end in abortion. The maternal infections that are transmissible from mother to fetus are caused by many pathogens, of which the TORCH complex contributes majorly to neonatal and infant deaths globally. The aim of this study is to detect the prevalence and types of infectious causes of abortion. One hundred aborted women admitted to King Faisal Medical Complex Maternity Hospital in Taif City between the period of 2018 and 2020 were enrolled in this study. The serological test reports (TORCH panel), as well as reports of hematological (CBC) and chemical parameters, were obtained from laboratory management system databases, reviewed, and then analyzed. The H&E-stained microscopic slides of their product of conception (POC) were examined under a microscope and compared with histopathological reports. The prevalence of TORCH infections was 8% in aborted women. Hepatitis B virus (HBV) and mixed TORCH infections constituted the highest percentage of TORCH pathogens in aborted women, constituting 6%. The most detected histopathological finding in seropositive cases (50%) was POC, with mixed inflammatory infiltrates and chronic endometritis, while in seronegative aborted women, POC was normal (64.1%). There is a statistically significant increase in the mean count of white blood cells in seropositive women. Therefore, it is important to provide health campaigns to bring awareness to the population about the risk factors of infectious agents to be avoided, especially during pregnancy.

Background The analgesic effectiveness of contemporary motor-sparing nerve blocks used in combination for analgesia in total knee arthroplasty is unclear. This network meta-analysis was conducted to evaluate the analgesic effectiveness of adding single-injection or continuous adductor canal block (ACB) with or without infiltration of the interspace between the popliteal artery and the capsule of the posterior knee (iPACK) to intraoperative local infiltration analgesia (LIA), compared to LIA alone, after total knee arthroplasty. Methods Randomized trials examining the addition of single-injection or continuous ACB with or without single-injection block at the iPACK to LIA for total knee arthroplasty were considered. The two primary outcomes were area-under-the-curve pain scores over 24 to 48 h and postoperative function at greater than 24 h. Secondary outcomes included rest pain scores at 0, 6, 12, and 24 h; opioid consumption (from 0 to 24 h and from 25 to 48 h); and incidence of nausea/vomiting. Network meta-analysis was conducted using a frequentist approach. Results A total of 27 studies (2,317 patients) investigating the addition of (1) single-injection ACB, (2) continuous ACB, (3) single-injection ACB and single-injection block at the iPACK, and (4) continuous ACB and single-injection block at the iPACK to LIA, as compared to LIA alone, were included. For area-under-the-curve 24- to 48-h pain, the addition of continuous ACB with single-injection block at the iPACK displayed the highest P -score probability (89%) of being most effective for pain control. The addition of continuous ACB without single-injection block at the iPACK displayed the highest P -score probability (87%) of being most effective for postoperative function. Conclusions The results suggest that continuous ACB, but not single-injection ACB and/or single-injection block at the iPACK, provides statistically superior analgesia when added to LIA for total knee arthroplasty compared to LIA alone. However, the magnitude of these additional analgesic benefits is clinically questionable. Editor’s Perspective What We Already Know about This Topic What This Article Tells Us That Is New

Background: The use of bone morphogenic protein and mesenchymal stem cells has shown promise in promoting bone regeneration in calvarial defects. However, a systematic review of the available literature is needed to evaluate the efficacy of this approach. Methods: We comprehensively searched electronic databases using MeSH terms related to skull defects, bone marrow mesenchymal stem cells, and bone morphogenic proteins. Eligible studies included animal studies that used BMP therapy and mesenchymal stem cells to promote bone regeneration in calvarial defects. Reviews, conference articles, book chapters, and non-English language studies were excluded. Two independent investigators conducted the search and data extraction. Results: Twenty-three studies published between 2010 and 2022 met our inclusion criteria after a full-text review of the forty-five records found in the search. Eight of the 23 studies used mice as models, while 15 used rats. The most common mesenchymal stem cell was bone marrow-derived, followed by adipose-derived. BMP-2 was the most popular. Stem cells were embedded in Scaffold (13), Transduction (7), and Transfection (3), and they were delivered BMP to cells. Each treatment used 2 × 104–1 × 107 mesenchymal stem cells, averaging 2.26 × 106. Most BMP-transduced MSC studies used lentivirus. Conclusions: This systematic review examined BMP and MSC synergy in biomaterial scaffolds or alone. BMP therapy and mesenchymal stem cells in calvarial defects, alone, or with a scaffold regenerated bone. This method treats skull defects in clinical trials. The best scaffold material, therapeutic dosage, administration method, and long-term side effects need further study.

Introduction: The COVID-19 pandemic has had major impacts on all healthcare services, including cardiac imaging. In this study, we investigate annual changes in cardiac imaging procedural volume and reimbursement among Medicare Beneficiaries (MB) from 2018 to 2020. Methods: We used the Center of Medicare and Medicaid Services database to identify a 100% sample of MB who underwent cardiac imaging procedures from 2018 to 2020. Using the Current Procedural Terminology (CPT) codes, we identified transthoracic echocardiogram (TTE), transesophageal echocardiogram (TEE), stress echocardiogram, and nuclear stress test procedures. We examined each procedure’s total, inpatient (facility), and outpatient (non-facility) annual volumes per 1,000 MB. We also examined the total annual Medicare reimbursement per imaging type during that period. We compared annual changes in volumes and total reimbursement between two-time intervals: 2018-2019 and 2019-2020. Results: All annual cardiac imaging procedural volumes decreased significantly in 2020 compared to 2019 ( P<0.001 ). The biggest change was observed in TEE, which decreased by 29.20%, followed by stress echocardiography (26.01%), nuclear stress test (22.96%), and TTE (10.68%). The decrease was more evident in the inpatient setting. Inpatient stress echocardiography decreased by 27.04% (vs 23.82% in the outpatient setting), nuclear stress test decreased by 24.82% (vs 20.66%), and TTE decreased by 11.03% (vs 9.58%). There was also a significant reduction in total annual reimbursement for all procedures in 2020 compared to 2019 ( P=0.0015 ). Stress echocardiogram, nuclear stress test, TEE, and TTE reimbursement decreased by 28.08%, 24.00%, 21.11%, and 15.79%, respectively. Conclusions: The COVID-19 pandemic was associated with a significant and abrupt reduction in annual cardiac imaging procedural volumes and total reimbursement among MB in both inpatient and outpatient settings.
