Is cancer risk reduced in multiple sclerosis? Results from a tertiary referral center.

BACKGROUND: Multiple sclerosis (MS) patients may be protected against cancer because of increased immune surveillance. However, aberrant T/B cell functioning in MS may increase the risk of cancer. We aimed to compare the frequency of cancer among patients with MS with an appropriate control group matched by the variables such as age, gender, tobacco smoking history, body mass index (BMI), and family history of cancer. METHODS: The MS patients who were registered and followed up at the MS Center in Hacettepe University Hospitals and appropriately matched with controls were included. A self-administered questionnaire with links to the online survey was delivered. RESULTS: Overall, 1037 responses out of 2074 in MS patients and 506 responses out of 1500 control group were included. Fourteen (1.35%) of MS patients and 18 (3.6%) of the controls were diagnosed with cancer. The odds ratio of having cancer in patients with MS compared to the control group was 0.389 (95% CI = 0.161-0.940, p < 0.05). DISCUSSION: There was no statistically significant difference in age, gender, tobacco smoking, and BMI between the groups after propensity score matching. The odds of having cancer were lower in our MS patients compared to the controls. The autoimmune changes responsible for the pathogenesis of MS may be responsible for the decrease in cancer risk.

Comparison of Drug-Coated Balloons With Drug-Eluting Stents in Patients With In-Stent Restenosis: A Systematic Review and Meta-Analysis.

In-stent restenosis (ISR) is the gradual narrowing of the stented coronary segment, presenting as angina or leading to an acute myocardial infarction. Although its incidence has decreased with the use of newer drug-eluting stents (DES), it still carries significant mortality and morbidity risks. We compared the 2 most common interventions for managing DES-related ISR: drug-coated balloons (DCBs) and DES. Electronic databases were searched to identify all randomized controlled trials comparing DCB with DES in patients with DES-ISR. The Mantel-Haenszel method with a random-effects model was used to calculate pooled risk ratios. Five trials comprising 1,100 patients (577 in DCB and 523 in DES group) were included in the final study. The mean follow-up was 42 months. DCB was found to have a higher risk for target lesion revascularization (risk ratio 1.41, p = 0.02) compared with DES. No difference was observed in all-cause mortality, target vessel revascularization, myocardial infarction, or stroke between the 2 intervention arms. In conclusion, management of DES-ISR with DCB has a higher risk of target lesion revascularization compared with re-stenting with DES. The 2 therapeutic interventions are comparable in terms of efficacy and safety profile.

Assessing the Efficacy of RADPAD Protection Drape in Reducing Radiation Exposure to Operators in the Cardiac Catheterization Laboratory: A Systematic Review and Meta-Analysis.

One of the leading environmental hazards, ionizing radiation, is linked to several detrimental health consequences in the body. RADPAD (Worldwide Innovations & Technologies, Inc., Kansas City, Kansas) is a sterile, lead-free, lightweight, disposable radiation protection shield. We conducted a systematic review and meta-analysis to determine the effectiveness of RADPAD protection drapes in the cardiac catheterization lab and how they can aid interventional cardiologists in becoming subjected to less scatter radiation. PubMed, Embase, and Google Scholar were searched for studies discussing the efficacy of RADPAD protection drapes in reducing radiation exposure to operators in the cardiac catheterization laboratory. A random-effects model was used to pool odds ratios (ORs) and 95% confidence intervals (CIs) for endpoints: primary operator exposure dose, dose area product (DAP), relative exposure, and screening time. Our analysis included 892 patients from six studies. Compared to the No-RADPAD group, primary operator exposure dose (E) was significantly lower in the RADPAD group (OR: -0.9, 95% CI: -1.36 to -0.43, I2 = 80.5%, p = 0.0001). DAP was comparable between both groups (OR: 0.008, 95% CI: -0.12 to -0.14, I2 = 0%, p = 0.9066). There was no difference in the relative exposure (E/DAP) (OR: -0.47, 95% CI: -0.96 to 0.02, I2 = 0%, p = 0.90) and screening time (OR: 0.13, 95% CI: 0.08 to 0.35, I2 = 0%, p = 0.22) between the two groups. The interventional cardiology laboratory is exposed to significantly less scatter radiation during procedures owing to the RADPAD protective drape. Consequently, all catheterization laboratories could be advised to employ RADPAD protective drapes.

Present Knowledge on Direct Oral Anticoagulant and Novel Oral Anti Coagulants and Their Specific Antidotes: A Comprehensive Review Article.

Thromboembolic diseases are one of the leading causes of morbidity and mortality worldwide. For a long time, heparin and Vitamin K antagonist (VKA) drugs were used for treatment and prophylaxis of the thromboembolic diseases. The development of newer direct and novel oral anticoagulant medications (DOACs/NOACs) has changed clinical practice significantly. Lesser monitoring, ease with dosing, less drug interactions have made these drugs useful to the providers and the patients. But these drugs have bleeding as a side effect. There is ongoing research on the specific antidotes of these anticoagulants in case of life-threatening bleeding. Though the use of the DOACs and NOACs have increased, there is still not enough clinical evidence about the specific antidotes of these medications. Unlike heparin or VKA, reversal of life-threatening bleeding in the setting of DOAC use is still a clinical challenge. We need more data on the dose, pharmacokinetics, and clinical efficacy of those antidotes. Authors have reviewed articles on DOACs and their antidotes in Pubmed and also in the clinical trial website. Specific antidotes including Idarucizumab for Dabigatran, Andexanet alfa for factor Xa inhibitors are being used to reverse the actions of the anticoagulants. Ciraparantag is a universal antidote for the DOACs, which is still under investigation. FXaI16L is currently being investigated as a potential universal antidote for multiple anticoagulants, including dabigatran and rivaroxaban. Though mostly safe, the use of DOACs can still carry a risk of severe bleeding in patients. More data on the use of the antidotes is required to reverse the side effect of DOACs if clinically indicated.

Assessment of Stem Cell Transplant Eligibility in Recipients with Oral Foci of Infection: Appropriate Conditioning Regimens.

OBJECTIVES: It is unclear whether patients with oral foci of infection should be approved for hematopoietic stem cell transplant with or without posttransplant cyclophosphamide. We compared the presence of oral foci of infection status on the effects of various conditioning regimens for such patients. MATERIALS AND METHODS: Three groups were classified as autologous (carmustine-etoposide-cytarabinemelphalan, mitoxantrone-melphalan, and melphalan 200 mg/m² groups; n = 502 patients), and 6 groups were classified as allogeneic (busulfan-fludarabinerabbit anti-T-lymphocyte globulin, busulfanfludarabine-posttransplant cyclophosphamide, fludarabine-cyclophosphamide-anti-T-lymphocyte globulin, busulfan-fludarabine-anti-T-lymphocyte globulin-posttransplant cyclophosphamide, total body irradiation-posttransplant cyclophosphamide, and other; n = 428 patients). Data were collected from a database that met international accreditation requirements. We evaluated dental radiological findings and calculated interobserver reliability. RESULTS: Oral foci of infections increased febrile neutropenia and bacterial infection frequencies in both groups but only increased mucositis frequency in patients with allogeneic treatment. The frequencies of oral foci of infection-related complications were similar in both the autologous and allogeneic groups. Rate of graft-versus-host disease was not affected by oral foci of infection status. Periodontitis/cysts and periapical lesions increased the risk of infections at day 100 in the mitoxantrone-melphalan group versus the melphalan 200 mg/m² group. We observed no differences among the autologous transplant groups in terms of early mortality. Similarly, no differences in early mortality were observed among the allogeneic groups. CONCLUSIONS: Transplant is a valid option in patients with oral foci of infections undergoing various autologous and allogeneic transplant protocols when time is of the essence, even at myeloablative dose intensities.

Asymptomatic Hyperuricemia as an Independent Risk Factor for Myocardial Infarction in Adult Population: A Four-Year Follow-Up Study.

Introduction A condition in which uric acid levels are elevated but there are no accompanying symptoms is known as asymptomatic hyperuricemia. As a result of the disparity in opinions and findings between the studies, the guidelines regarding whether or not asymptomatic hyperuricemia should be treated are unclear. Material and methods Between the months of January 2017 and June 2022, this research was carried out in the community in collaboration with the internal medicine unit and the public health unit of Liaquat University of Medical and Health Sciences. After obtaining informed consent from each participant, the researchers enrolled 1,500 patients in the study who had uric acid levels that were greater than 7.0 mg/dL. These patients ranged in age from 40 to 70 years old and were of either gender. As a control group, 1,500 patients were recruited who did not have abnormally high levels of uric acid. Patients were monitored for a total of 48 months or until the occurrence of a major cardiovascular event (MACCE) or death from all causes, whichever occurred first. Death, cardiovascular mortality, non-fatal myocardial infarction, and non-fatal stroke were the four categories that made up the primary outcome, also known as MACCEs. Results In the hyperuricemic group, the incidence of myocardial infarction that did not result in death was significantly higher than in the non-hyperuricemic group (1.6% vs. 0.7%; p-value, 0.04). However, the result was not significant for deaths from all causes, deaths from cardiovascular disease, or strokes that did not result in death. Conclusion Asymptomatic hyperuricemia is a potential threat to one's health that can lead to cardiovascular diseases and may go undiagnosed in some cases. It is important to remember that hyperuricemia can lead to delirious complications, so efforts should be made to perform routine monitoring and management of the condition.

Correlation of Depression and Anxiety With Rheumatoid Arthritis.

Background Psychiatric comorbidity with a chronic disease is linked with poor patient outcomes. Therefore, the current research assessed the correlation of rheumatoid arthritis (RA) with depression and anxiety disorders.  Methodology A prospective observational study was undertaken at a public sector hospital between December 2020 to June 2021. All individuals who presented with rheumatoid arthritis were included in the study. A healthy cohort acted as the control group. Depression and anxiety were assessed using the Hamilton depression rating scale (HDRS) and the Hamilton anxiety rating scale (HAM-A), respectively. The patients were inquired about their gender, age, and duration of RA. Further stratification was done using the Chi-squared test. A p-value of <0.05 was decided as the cut-off for significance. All data from the patients were collected in a predefined pro forma.  Results A total of 169 patients with RA and 85 healthy controls were enrolled in the study. The mean depression score among patients with RA was 19.65 ± 1.44 versus 14.4 ± 1.31 in the control group (p<0.001). Moreover, the mean anxiety score in patients with RA was 19.44 ± 2.4. About 71% of patients with RA were diagnosed with psychiatric issues, while only 7.1% of individuals in the control group had either depression or anxiety (p<0.0001). Furthermore, it was found that the majority of the patients with RA had depression with a frequency of 70 (58.3%), while only six participants in the control group had depression. None of the participants had moderate or severe depression. However, 16 (69.6%) patients with RA had major anxiety issues. In 27 patients, mixed anxiety-depression disease was diagnosed. Out of these, 23 (85.2%) had the depression-dominant mixed disorder.  Conclusion The present study highlighted the alarming incidence of depression and anxiety among patients with RA. Furthermore, it also indicated the relationship between severity of psychiatric comorbidity with chronic rheumatoid arthritis in our population. Further large-scale studies are needed to ascertain the demographic confounders that may help predict psychiatric disorders among patients with RA.
